The Wiley-Blackwell Publishing House Style Guide and its online version have been produced for
the use of editors, production editors, freelances, copy-editors, authors and typesetters. The level
of consistency that this guide promotes is intended to assist all those involved in the production
of Wiley-Blackwell (WB) publications. The WB definition of copy-editing is best described as
technical or mechanical editing, which involves language editing, mechanical style (style related to
content) and format (visual style). Technical or mechanical editing includes applying house style,
technical style, formatting, consistency and correcting grammar. Creative or substantive editing is
not usually within the remit ofthe WB copy-editor and is not commented upon. This guide is not
intended to be a comprehensive account ofall that is necessary for the presentation of research
material, and should be used in conjunction with texts that have greater scope (see recommended
references). Some journals and subject areas employ their own systems and conventions and the
intention is not to impose upon them a rigid style, but rather to establish a framework within
which they can operate.
The online version ofthis guide, available at www.blackwellpublishing.com/housestyle, will
be updated on a regular and on-going basis and should be regarded as the definitive version.A
separate guide is available for US journals.

1.1 Copy-editing
Journals and articles varyin the amount of editing required, depending on the thoroughness
of the editor and the standard ofthe text supplied. Copy-editing usually involves:
•applying journal style
•applying Wiley-Blackwell house style where no specific journal convention exists
• formatting text
•making text consistent
• correcting English to ensure the article is readable
STY L E AND FORM AT T I N G
Check your journal style sheet for the styles of authors’names, addresses and affiliations,
correspondence details,keywords, table and figure captions, etc., and for the formatting of text
(e.g. use of small text in some sections).
C O N S I S T E N C Y
The following should all be usedconsistently:UK/US spellings, alternative spellings, grammar,
punctuation, italics, Greek letters, diacritics, hyphenation, capitalization, abbreviations and
contractions. References and their citations should be consistent and complete. Make sure that all
figures and tables are present and match their legends, and that they are cited in order.
CO RR E C TION OF E NG L I SH
You may need tocorrect spelling, punctuation, grammar and syntax, and to edit for sense. If text is
ambiguous, add a query to the author asking for clarification. Do not rewrite or delete large
sections of text.
1.2 English Usage and Grammar
V O I C E
The tendency to present scientific text in the passive voice is fading.Most Wiley-Blackwell journals
and readers now accept use ofthe active voice. Unless the journal has a strict requirement for the
active or passive voice, follow the authors’preference,as long as this is consistent within the
manuscript.
Be wary ofthe passive voice in the Discussion,as it can sometimes be unclear whether the authors
are talking about their own work or that ofother people. You may need to use phrases such as ‘in
the present study, it was found that …’ to clarify this.
T E N S E
Methods usedand results obtained by the authors should be referred to in the past tense:
•mice were given two types of grain
•mice in group Aate 50 mg of grain
© 2007 John Wiley & Sons Ltd
5
The past tense will therefore generally be employed in the Abstract, Methods and Results sections.
The past tense should also be used to talk about specific findingsof previous work:
•Smith (1990) found that yield decreased by50%
Interpretation of results should be in the present tense:
•the results for groups A and B aresignificantly different
The present tense will therefore generally be employed in the Introduction (except, for example,
when the authors are stating what their hypothesis and aims were before the study commenced).
The present tense should also be used in the Discussion when the results are being interpreted:
•Our studyshows that a significant number ofFinnish people speak Finnish
Findings of previous studies should also be referred to in the present tense if they have become
generally accepted‘facts’:
•treatment X results in Y, as demonstrated by Jones (1978)
•the expression ofclass I genes varies amongst haplotypes
Watch for mistakes in the use oftenses in manuscripts from non-native English speaking authors
(native English speakers tend to use the correct tense instinctively).
SUBJ ECT AND VER B A GREEMEN T
Verbs must agree in number with the sense and form ofthe subject. Check whether a noun is plural
or singular and make sure that the verb agrees.
• Collective nouns, e.g. school, number, family and committee, usually take singular verbs but
can take plural verbs if the emphasis is on the individual rather than on the unit itself, e.g.the
committee has agreed to extend the deadline; the committee have been at odds from the beginning.
•Note the difference between mass nouns (which do not have countable elements) and count
nouns (which identify things that can be counted), when used with pronouns (all, any, none,
some), e.g. some ofthe sky was visible; some ofthe stars were visible.
• Units usually take singular verbs, e.g. 150 mL of blood was sampled.
•Take care with Latin and Greek nouns such as data, media, errata, criteria and phenomena,
which are plurals; singulars are datum, medium, erratum, criterion and phenomenon (an
exception is data processing): data are presented; dual-medium filters were used; two
phenomena were classified using one criterion.
US E OF T H ATAN D W H I C H
That is used for defining or restrictive clauses:
•The patient made a list ofthe symptoms that were most troublesome
A defining clause is specific (limiting) to a particular person or thing; i.e. the patient had to list
only those particular symptoms that were most troublesome.
Which is used in nondefining or nonrestrictive clauses:
•The patient made a list ofthe symptoms, which were most troublesome
A nondefining clause is general (nonlimiting); it provides additional information, and the use of
commas is often important. In this example, all the symptoms were very troublesome.

DA N GL I N G PA R T I C I P L E S
These frequently occur where the passive voice is used, and they can link an action to an agent that
is incapable of performing it. The clause ‘the ribosomes could be observed using a microscope’
should be reworded:‘the ribosomes were observed by using a microscope’or‘using a microscope,
the ribosomes were observed’.
R E D U N D A N C Y
Avoid using a modifying word when the intended meaning is inherent in a word already used.
Redundancy is obvious in examples such as the results were plotted graphically,past history, bright
blue in colour, inactivates its activity and completely filled. Does the term careful monitoring suggest
that the alternative is careless monitoring?
DE FINI TE A ND IN DEFINI T E ART I C L E S
Many non-native English speaking authors have some confusion about when to use the definite
(the) and indefinite (aand an) articles.
✗… to determine effect ofthe salinity on grain yield of wheat
✓… to determine the effect of salinity on the grain yield of wheat
Also be aware that use of definite and indefinite articles in titles can differ from that in ordinary
text:
✓Effect of Salinity on Grain Yield of Wheat
See the recommended usage guides for guidance on the use ofthe indefinite article with words
beginning with ‘h’(e.g. a hotel; an hour).
I N A C C U R ATE P HRA S ES
Be accurate in your word choice. For example, dose is the amount of drug given at one time;
dosage is the regulation or determination of doses.
US E OF ‘O NLY ’
The position of the word ‘only’ can lead to ambiguity, e.g.‘the doctoronly sees patients in the
morning’could mean ‘only the doctor sees patients in the morning’;‘the doctor sees patients in the
morning only’, or‘the doctor sees only patients in the morning’.
BA L AN C I NG A SENTE NCE
It is important to ensure that a sentence balances on either side of certain words (correlatives) that
emphasize similarity or contrast and that are used in parallel:both and and;either and or;neither
and nor;not onlyand but;between and and;whether and or. For example,‘I swam both in the
morning and afternoon’ should be‘I swam both in the morning and in the afternoon’ or‘I swam in
both the morning and the afternoon’. Note the position ofthe preposition in.(See also the section
‘Editing for Sense’.)

C O M PA R AT I VE S AN D SU P ERLATI V ES
•If you are comparing two things, or two groups of things, or one thing with a group of things,
you should use a comparative,not a superlative.
✗Jim is tallest compared with David, John and Mike
✓Jim is the tallest ofthe four men
✓Jim is taller than David, John and Mike
•Do not use ‘relatively’ with a comparative,e.g. relatively less. This is tautology;‘relatively’
should be deleted.
•Make sure that it is clear what is being compared with what (e.g.‘in patient 3, there was greater
reactivity for P. gingivalis in dental plaque from the first molar’… Is‘greater’ being used to
compare patients,bacteria or sites in mouth?).
MI S CELLA NEO US PO I NTS
‘Male’and ‘female’ are adjectives, so be careful to use them as such (i.e. a male patient and a female
frog,but a 35-year-old man,a French woman and a group of25 men and 35 women). Many authors
get this wrong.
EXP R ESS IO N S TO AV O I D
•Since should be used only with reference to time,and not for because.
•Although is preferred tothough.
•Done,as in the experiment was done, should be replaced with performed or carried out.
•Parameter should only be used to describe a defining limit, and is not interchangeable with
variable.
•A lot ofshould be replaced with manyor, preferably, should be defined more precisely.
•Avoid get and got.
•As a result ofor because ofare preferred todue to.
•Hopefully should be avoided.
•Try to avoid references in the text tosee belowor in the Results section.
•Use dependency only for foreign territories; otherwise use dependence.
US E WITH CAU TI O N
Be aware of potentially litigious content, for example the naming of patients or criticism of the
actions of individuals, organizations or companies.
P O L I T I C A L LY SEN S I TIVE TER M S
Race and ethnicity
Try to avoid the terms Blacks and Whites;use insteadBlack people,White people, etc. Caucasian,
Mongoloid,Negroid, etc. are generally to be avoided, except in human population studies. Mixed
race is preferable tohalf-casteor coloured.
Disabilities
•People with disabilities not the disabled
•People with learning difficulties not mentally handicapped
© 2007 John Wiley & Sons Ltd

![](asset-9.png)
Gender
Use neutral nouns: avoid the use ofman if not specifically referring tomen; for example, for man
use humans; for mankind use the human race; for manpower use workforce; for manmade fibreuse
synthetic fibre. Use inclusive pronouns: use he or she,or rephrase the sentence (rephrasing to the
plural form often works):
✗Any observer of changes in publishing technology will perceive that he has need of…
✓Observers of… will perceive that they have…
Beware of referring to people with stereotypical pronouns (e.g.‘the doctor treated his patient’;‘the
secretary tidied her desk’). Social classes and age groups should also not be stereotyped.
Disease
Avoid health-determined categorization. Use people with diabetes not diabetics;people with cancer
not cancer sufferers, etc. Avoid phrasing that dehumanizes a patient: many authors use case
(instance ofa disease) when they mean patient (person who is ill with the disease).
Sexuality
Avoid the terms homosexual activities (specify which activity is being referred to) and homosexuals
(specify homosexual men or lesbians).
Geography
The terms ThirdWorld,poor countries and underdeveloped countries should beavoided.Developing
or nondeveloped country/society is better, but it is best to specify countries or regions instead.
Western society and Western World should only be used in relation to geography; otherwise, use
developed world/society or, even better, specify the countries themselves or the region.

AIDS
•Ensure that AIDS is used for the disease and HIV for the virus, e.g. do not use AIDS carrier,
AIDS positive,AIDS virus or catching AIDS.
•AIDS sufferer/victim is inappropriate; use people with AIDS.
•People who practise high-risk activities not high-risk groups.
•The expression full-blown AIDS is unnecessary if the correct distinction has been made
between HIV and AIDS.
Key points
•It is now acceptable touse the active or the passive voice.
•Use the past tense for the author’s methods and results, and the present tense for
interpretation and generally accepted‘facts’.
•The subject and verb must agree in number.
•‘That’is defining;‘which’is not.
•Check that articles (‘a’,‘an’and ‘the’) are used correctly.
•Sentences must balance(e.g. with ‘both… and…’).
•In comparisons (e.g.with lower/higher/less/more), make sure it is clear what is being
compared with what.
• Avoid sexist, dehumanizing and stereotypical language.
![](asset-a.png)
1.3 Editing for Sense
You do not need knowledge ofthe subject matter to be able to edit for sense. Often it will be
obvious what the author is trying to say, in which case you do not need to add a specific query (e.g.
‘with this investigation the effects ofantibiotic treatment were inquired’can safely be changed to
‘in this investigation, the effects of antibiotic treatment were investigated’). However, if you are
having to make substantial changes,add a query to the beginning ofthe article telling the authors
that text has been reworded throughout and asking them to check carefully.
Be very careful not to change the meaning. It should always be your goal to makeonly the changes
that arenecessary. If in doubt, leave unchanged and ask the author for clarification.
AM BIG U O US T EX T
When text is ambiguous, the intended meaning is sometimes obvious from the context and
rewording is straightforward. If this is not the case, you must query the authors. It is best, if you
can, to give them two (or more) choices rather than just asking what they mean.
Phosphorylated hexoses: glucose-6-P and fructose-1-P, repress the expression of many resistance
genes.
Query Do you mean ‘Phosphorylated hexoses, such as glucose-6-P and fructose-1-P, repress the expression of
many resistance genes’ or‘The phosphorylated hexoses glucose-6-P and fructose-1-P repress the expression of
many resistance genes’ or something else?
Misplaced modifiers (words or phrases that limit or qualify the sense oftext) can create ambiguity
about what they are modifying.
✗She continued editing after the meeting finished early because she had to send the issue to the
typesetter
✓Because she had to send the issue to the typesetter,the meeting finished early and she continued
editing
✓After the meeting finished early, she continued editing because she had to send the issue to the
typesetter
NO N SE Q U I TUR S
Look out for text that does not logically follow what goes before (e.g.‘humans and mammals…’
should be changed to‘mammals,including humans, …’ because humans are mammals).
✗Forage turnip is widely grown in northern Europe, but it is distributed over much of
northern Asia, northern North America and southern Oceania.
✓Forage turnip is widely grown in northern Europe and is alsodistributed…
Sometimes it is not clear what the author means to say.
The sensitivity ofbarley seedlings changed after 4 weeks of cold treatment, but decreased after 6
weeks.
Query Do you mean ‘The sensitivity ofbarley seedlings began to decrease after 4 weeks… and decreased further
after 6 weeks’ or ‘The sensitivity ofbarley seedlings increased after 4 weeks…. but decreased after 6 weeks’?
These results are in conformity with the results of Smith et al. (1984). This provides acid
production in vitro observed over a period oftime by Jones (1980) also.

BA L AN C I NG SE NTE NCES
Use parallel grammatical constructions with conjunctions (and, but, etc.) and in comparisons.
✗the titre in week 2 increased by 50% for patient 1, and by 60% for patient 3 in week 4
✓the titre increased by 50% for patient 1 in week 2,and by 60% for patient 3 in week 4
✗… to evaluate the relationships between clinical (e.g. stroke impairment,functional status,
depression, and side of stroke lesion) and sociodemographic (e.g. age, gender, marital status
and emotional support) factors
✓… to evaluate the relationships between clinical (degree ofstroke impairment, functional
status, presence/absence of depression and side of stroke lesion) and sociodemographic (age,
gender, marital status and extent ofemotional support) factors
✗Detection of immunostained proteins by light microscopy is not as clear as electron

✓Detection ofimmunostained proteins by light microscopy is not as clear as that byelectron

P R O N O U N S
Watch out for pronouns that refer back to the wrong noun.
The pellet was dissolved in 100 mL of distilled water.It was then filtered through Whatman no. 41
paper.
Change ‘It’to e.g.‘This solution’(‘the pellet’ can’t be filtered!).
F E W E R / L E S S
Although more can be used for both countable (e.g.more stars) and uncountable (e.g.more rain)
nouns, fewermust be used for countable nouns (e.g.fewer stars,fewer cups of tea,fewer examples)
and less for uncountable nouns (e.g.less rain,less tea,less information).
✗Less people
✓Fewer people

Key points
• If text does not make sense or is likely to cause the reader problems, change it and, if
necessary, add a query to the author.
•Look out for ambiguous text and non sequiturs.
•Make sureparallel grammatical constructions are used with conjunctions and in
comparisons.
• Pronouns must refer back to the correct noun.
• Fewer/less,strong/high/low and weak/low/smallare often used incorrectly.
•Check that subject/verb and noun/adjective pairs make sense (e.g.in ‘the highest patient
for recovery score’,the adjective has been attached to the wrong noun).

1.4 Spelling
Spelling should beconsistent within an article.When two or more spellings ofa word are given in a
dictionary,the first listed is generally the one preferred.

Accents and diacritical marks
These are marks attached toletters of the alphabet that show (i) how the pronunciation differs
from that ofthe unmarked letter,(ii) where the stress falls in a polysyllabic word or (iii) what tone
or pitch goes with a particular word.
• German Use ß (eszett) for ss, but only in lower case (and note that not all ss are ß); in caps
(and small caps), SS is always used. Use umlauts over ä, ö and ü rather than using the
respective diphthongs ae, oe and ue. Remember that, in German, all nouns have initial caps
(e.g. ein Haus, das Sein) and they should retain these when italicized.
• French Upper-case letters carry accents, e.g. RÉSUMÉ.The exception is the preposition à,
e.g. A la porte.
• Scandinavian characters should be alphabetized as follows:
…Z, Æ, Ø, Å (Danish, Norwegian)
…Z, π, Æ, Ö (Icelandic)
…Z, Å, Ä, Ö (Finnish, Swedish)
Foreign names
Take care with the capitalization of particles in foreign names (e.g.Philippe Du Puy de
Clinchamps,Vasco da Gama, Vincent van Gogh). These appear in lower case except at the start of a
sentence or when the name is anglicized. Generally, just use what the author provides. In reference
lists, lower case particles are listed under the letter ofthe name proper but upper case particles
under the letter ofthe particle (e.g.da Silva under‘S’but Von Trapp under‘V’). Do not abbreviate
‘Saint’and ‘Sainte’in French surnames. Some Japanese and Chinese names are presented with the
surname first, so be careful when filing these in a reference list. Spanish and Portuguese names are
sometimes composed of two family names (mother’s and father’s) and should be listed under the
penultimate element (e.g. Federico Gutierrez Granier should be listed under Gutierrez).
Hyphenated Asian names do not take a full point after the first initial (e.g. Jen-Yi Hwang is J-Y.
Hwang not J.-Y. Hwang; cf. Jean-Marc Lafayette,which is J.-M. Lafayette).

Context
Not essential where a conjunction is used between
two clauses unless there is a change of subject
Used to isolate a word, phrase or subordinate
clause
Used to isolate nondefining clauses
Not used to separate sentences
Used in lists
‘Therefore’ should not be enclosed within commas
when used as an adverb
Used to clarify a sentence
Examples
We tried to resuscitate the patient but to no avail.
Resuscitation is possible, but brain damage is likely.
Resuscitation, although dangerous, is possible.
On revival, the patient was monitored regularly.
… days 3, 4 and 10, respectively.
Therefore, the experiment was….
The cells, which were infected, were excised.
The commas help to isolate the nondefining clause
(see differences between ‘that’ and ‘which’above).
✗The cells produced more lactate, however they
did not produce acetate.
✓The cells produced more lactate; however, they
did not produce acetate.
The solution contained 200 mg of glucose, 100 g of
ascorbic acid and 500 mL ofdistilled water.
UK English: a comma before ‘and’ (known as the
Oxford comma or serial comma) is unnecessary in
the above example, but it may be used in lengthy
lists or to avoid ambiguity.
US English: authors prefer to place a comma before
the ‘and’ here.
These samples were therefore discounted.
The precipitate formed after shaking on the bottom
makes more sense with the addition of commas,
thus:
The precipitate formed, after shaking, on the bottom.

AP OST R OP HE S AN D PRI ME S
Apostrophes should be used to identify possessive nouns, e.g. the body’s defence system,the girls’
hats. Such words ending in ‘s’should still be followed with an apostrophe ‘s’, e.g. Claudius’s reign.
An apostrophe should not be used where an acronym, abbreviation, date or number is pluralized:
ANOVAs, 1980s, etc. Where apostrophes are used to indicatemissing letters in informal English
(e.g. I’m, we’re, he’s; it’s not clear; there’re many patients; it’s been found), it is usually preferable to
write the words out in full (e.g.it is not clear; there are many patients; it has been found).
Look out for its (possessive; e.g.its tail) and it’s (‘it is’or‘it has’; e.g.it’s got a tail).
St Thomas’ Hospital
Queens’ College, Cambridge
The Queen’s College, Oxford
Primes (´) are used to denotederivatives of mathematical variables (e.g.aand a´) and for minutes
of angle (e.g. 12°14´N). They should not be used instead ofthe standard abbreviation‘min’ for
minutes of time.
H Y P H E N S
Journals will often have a specific hyphenation style, for which you should refer to your journal
style sheet. Also check the relevant dictionaryif necessary. Make a decisionabout hyphenation
and apply it throughout the typescript, taking into account the author’s style, the likely readership,
and the meaning of individual words and phrases. Minimal hyphenation is generally preferred.
Prefixes
DO hyphenate… prefixes that stand as words in their own right (e.g. cross, half, all); these are
usually hyphenated when used as adjectives (e.g. cross-section,half-life, all-inclusive). There are,
however, more than a few exceptions (e.g. outpatient, crosshatched, overexposed). Hyphens are
also needed when a prefix is attached to a word or phrase starting with a capital letter (e.g. anti-
HLA,non-Euclidean,sub-Alpine).
DO NOT hyphenate… prefixes that cannot stand as words in their own right (e.g. anti, bi, co,
hyper, hypo,infra, inter, intra, micro, multi, palaeo, peri, pre, pseudo,re, sub, supra, ultra, uni);
these are usually closed up when used as adjectives, unless two vowels or the same consonants abutt
(e.g. hyper-reactive, pre-operative, anti-inflammatory, co-opted,re-election; NB US authors are
less inclined to use hyphens in such cases). Note, however, that this rule may need to be broken (e.g.
ultra-high-vacuum environment, pseudo-first-order distribution, re-create). If in doubt,follow
the author’s style.
Compound terms
DO hyphenate… many compound terms and adjectives (e.g. iron-rich sediments; salt-leached
water; 19-year-old boy but boy aged 19 years; T-cell receptorbut T cell), particularly where the
meaning would otherwise be ambiguous. In more complex examples, the second hyphen normally
has priority over the first (e.g.‘T cell-receptor expression’ would often be preferred to‘T-cell-
receptor expression’; but ‘10-cm-diameter pots’, not ‘10 cm-diameter pots’). The second part of a
compound term used in a book case heading should not be capitalized (e.g. Subject-specific
Conventions).

![](asset-11.png)
DO NOT hyphenate… compound adjectives consisting ofa past participle preceded by an adverb
ending in ‘-ly’ (e.g. dermatologically tested soap). It is not necessary to use hyphens for well-
established compound terms whose meaning is clear (e.g.amino acid residues, freezing point
determination). Avoid floating hyphens (e.g. phosphorus- or sulphur-containing compounds).
Try to reword the sentence to eliminate the need for the floating hyphen, but be careful not to
change the sense (e.g. if the hyphen is removed after ‘phosphorus’ in the sentence above, the sense
changes).
Chemical names
Hyphens are often used in chemical names (e.g. 2-mercaptoethanol, a1-antitrypsin).
Miscellaneous
•Avoid bad word breaks at the ends oflines (e.g.pseud-obedding;the-rapist)
•10-fold but twofold
•Two-thirds, thirty-seven
•North-west
•Inpatient and outpatient (not hyphenated)

S E M I C O L O N S
•The semicolon is stronger than a comma but not as decisive as a full point. It can be used to
separate sentences (whereas a comma cannot).
•Use a semicolon before, and a comma after,the conjunctive adverbs however, that is,
nevertheless, etc.
C O L O N S
Colons are used to introduce material that restates, explains, enlarges upon or summarizes
previous material. They also introduce items in a list set off from text (but a colon is not needed in
run-on lists introduced by the words for example,namely,including, etc.; e.g. in the sentence ‘The
pavlova looks nice with red fruit on it, for example: strawberries, raspberries and redcurrants’the
colon should not be there).
•In UK spelling,a capital letter is not used after a colon (except in titles and subtitles). In US
spelling, if the material introduced by a colon consists of more than one sentence, or if it is a
formal statement, quotation or speech in dialogue it should take a capital after the colon.
• Ratios containing words should have a thin space on each side ofthe colon (e.g.the light : dark
cycle) but ratios containing numbers should be closed up (e.g. 16:8 h).

Key points
•Use commas to clarify sentences.
•Do not use a comma to separate sentences;use a semicolon (this is a particularly common
error before‘however’and ‘nevertheless’).
•Do not use apostrophes with plural abbreviations (e.g. ANOVAs, not ANOVA’s).
•For hyphenation, refer to your journal style sheet.
•Do not hyphenate adverbs ending in -ly(e.g. dermatologically tested soap).
•Use hyphens in compound terms to clarify meaning (e.g. six-well plates).
•Use en rules,not hyphens, for associations (e.g. dose–response curve).
For You should use Example
Complex associations Hyphen and en rule oak-forest–hazel-scrub interaction

1.6 Units
Check your journal style sheet for the use ofunits (e.g.some journals use a negative index and
some use a solidus to indicateper).
DO USE
• Abbreviations for seconds (s), milliseconds (ms), minutes (min), hours (h), million years
(Myr), million years ago (Ma) and billion years ago (Ga).(Exceptions in running text are e.g.
5 minutes’ walk and five-minute start.)
•Ahyphen with units as adjectives (e.g.30-cm ruler, 2-min test, 5-kb fragment), unless this is
not journal style.
•Either a solidus (/) or a negative index (–1,–3,etc.) for per (e.g. 5 m/s or 5 m s–1).
•Figures for quantities that are measured in units, but words for numbers of objects less than
10 (e.g.5 years but five dogs; also fifth but 15th). However, it may be better to break this rule if
an inventory of objects is presented (e.g.13 cats,8 dogsand 24 mice).
•En rules for ranges of values (e.g. 15.4–27.6 g), except for values used with linked prepositions
(e.g. between…and).
•Système International (SI) units,unless instructed otherwise.
•Closed-up figures for numbers in the single-digit thousands (1000–9999), and thin spaces in
UK English for numbers of five figures and over (US English uses commas not spaces) (e.g.
12 624, 200 000 000).However, it is usually preferable to express large numbers using factors
of 10 (e.g. 3.75 ×107cells/L).
•A unit term as a singular entity when considering subject–verb agreement (e.g. 5 g was…).
•Numbers and their units in full at the start ofa sentence (e.g. Fifty-eight kilograms ofgrain…).
•Thin spaces between numbers and units, and between units (e.g.10 min, 6.5 W,20 °C,
47.6 m/s 5 mg mL–1,but 4% and sometimes 20°C).
DO NOT USE
• Abbreviations for days, weeks, months and years.
• Acre;use hectare (1 acre = 0.4047 ha).
•Ångström;use nanometres (1 Å = 0.1 nm).
• Calorie;use joules (1 cal = 4.186 J).
•×before gravitational force(e.g. 15 000 gnot 15 000 ×g). Also, do not use r.p.m. as the unit for
gravitational force, except for ultracentrifugation, where r.p.m. is usually given together with
the centrifuge model and manufacturer and the rotor code (e.g. SS34).
•En rules with linked prepositions (from and to; or between and and) (e.g.between 10 and 15
days,not between 10–15 days).
•m for micron;use µm.
•N orN(small caps) for normal concentration:ask authors to provide the molar
concentration.
•p.p.b. for parts per billion;use ng/g.
•p.p.m. for parts per million;use mg/g.
• Percent. Use either % or per cent.
•A unit term as a plural (e.g. 10 mL was… not 10 mL were…).
© 2007 John Wiley & Sons Ltd
19
![](asset-14.png)
• Repeated units (e.g.between 10 days and 15 days should be written between 10 and 15 days).
• Superfluous material in units. For example, in the expression‘organic carbon at a
concentration of 56 mg C/L’ the symbol for carbon is superfluous in the unit;‘organic carbon
at a concentration of 56 mg/L’is sufficient.
•Lots ofzeros in numbers. Add unit prefixes so that values are≥1 and <1000 (e.g. 0.081 g/L
should be changed to 81 mg/L, and 1.67 ×10–7 m to 167 nm). However, always inform the
author/editor of such changes and seek their approval.
•Expressions such as 20 mg/100 mL;use 200 mg/L.
MI S CELLA NEO US UN I TS
CFU colony-forming units
Da daltons (do not use d)
IU international units
L litre; this is now preferred to l
(lower-case L)
mL = millilitre = cm3(do not use cc)
mmHg millimetres of mercury only in medical work; otherwise, use pascals (1 mmHg = 133 Pa)
MO L E A ND M O L AR
It is recommended that you use mol for mole and mol/L or mol L–1 for molar. However,some
styles use M for mole and M(small caps) for molar.

Key points
•There should be a thin space between numbers and units (e.g.10 days), or a hyphen in
compound adjectives (e.g.10-day cycle).
•For per,use a solidus or a negative index, depending on journal style.
•For quantities,use figures (e.g.5 mL); for numbers of objects less than 10, use words (e.g.
five patients).
•A unit term is singular (e.g. 10 mL was added…).
•Do not use en rules with linked prepositions (e.g. between 10 and 15 days,not between
10–15 days).
•Do not repeat units unnecessarily (e.g.not 10 days and 15 days).
•L for litre is now preferred to l.
•Use Da for daltons,not d.
Unit prefixes
m milli (10–3) k kilo (103)

1.7 Italics
To find out whether a word should be italicized, check the latest edition ofthe recommended
dictionary.You should also refer to your journal style sheet for journal-specific usage (e.g. for et al.
and variables such as P).
E X A M P L E S
© 2007 John Wiley & Sons Ltd
21
DO italicize
Foreign language phrases that arenot in common
usage (e.g.ad libitum,en bloc,sensu lato). These are
better presented in italics than in inverted commas.
Book and journal titles
Names of parties in legal cases
Genus and species names
(e.g. Homo sapiens)
Abbreviations for genes
(e.g. ced-3 for the C. elegans cell-death gene)
Symbols and abbreviations that represent variables
(e.g. x-axis, n)
Parentheses (like these) within italic text.
DO NOT italicize
Foreign language phrases that arein common
usage (e.g. alias, per annum, vice versa). The fact
that a word has made it into an English dictionary is
a good indication that it is familiar (or at least can
be looked up), so it can be set in roman.
Names ofpeople (except in legal cases), places or
institutions
Family, order and class names
(e.g. Hominidae, Primates, Mammalia)
Modifiers to species names (e.g. cv., var., ex., ssp.),
and authorities (e.g.L.)
Abbreviations for gene products
(enzymes/ protein) (e.g.CED-3)
Symbols, abbreviations and whole words that
represent constants (e.g. e, π), functions
(e.g. f, exp,log) or modifiers (e.g.na,nair).
Parentheses around italic text (like these).
Italic words used in italic headings

1.8 Quotations
Every quotation should be accompanied by a reference to its source (e.g.Author 2003).
Short quotations (< 30 words) ‘should run on within the normal sentence structure’(Author
2003). Use quotation marks to distinguish the quote, and,if appropriate, precede by a comma (for
shorter quotations) or a colon (for longer quotations).
Long quotations (>30 words) should be displayed.
Displayed quotations do not require quotation marks. They should be set smaller than normal text type
and indented by the normal paragraph indent, with no extra space above or below.
(Author 2003)
The spelling, grammar, etc. of direct quotations is not edited. Check that direct quotations have
not been changed by any macros that have been run on the paper. Use ‘[sic]’(always in square
brackets and italic) to signify a direct quote ofan error.
Direct speechis the exact quotation ofanother person’s words. Punctuation should be placed
inside the quote marks when it belongs to the quotation or before mention ofthe speaker.
•‘This is an important finding,’ the Director-General said.
•He asked,‘Why did you do it?’
Punctuation should be placed outside the quote marks when it does not belong to the quotation.
•WHO declared TB ‘a global emergency’.
SIN GL E O R D OU BLE?
It is UK and Australian style to use ‘single’quotation marks, with closing punctuation outside
marks (unless it belongs to the quoted material), and “double” marks for quotes within quotes.
It is US style to use “double”quotation marks, with closing punctuation (except colons and
semicolons) inside marks, and ‘single’marks for quotes within quotes.
Use a thin space between single and double quotation marks if they occur next to each other.
1.9 Lists
An itemized list that is part ofthe text should continue the punctuationof the sentence that
precedes it, so:
•if preceded by a colon the list should begin with a lower case letter;
•there should be a full point at the end ofthe sentence.
For long,complicated lists with internal sentences, each item ofthe list should start with an initial
capital, in which case the sentence preceding the list should be rewritten toend in a full point.
1Check your journal style sheet for the style of numbered lists.Often, a bold number followed
by a tab is used. Lists within lists should be indented, and have a different style of numbering
from the main list (e.g. Roman numerals).
2Some styles have extra space above and below lists, but some do not.
3Lists ofdefinitions ofabbreviations should be displayed or, if set in continuous text, should
have individual entries separated by commas and semicolons,not equals signs (e.g.Y, young;
M, middle-aged; O, old; VO, very old).

1.10 Footnotes
•See your journal style sheet for the formatting of footnotes. On the title page, there may be a
mixture of footnotes using numbers and symbols (e.g.for author affiliations or
‘correspondence’ details), depending on the journal style.
•Check for consistency of footnote links in text/tables with the footnotes themselves.
•Footnote links should be placed after punctuation.
•The preferred order of footnote symbols (which should not be superscripted) is *,†,‡,§,¶
(these are doubled up if more footnotes are required, e.g.††).
•When superscript numbers or letters are used, beware of potential confusion with other
superscripts (e.g.2for‘squared’).
IN TE XT
Footnotes in the text are not encouraged for journals that are full text online. Sometimes it may be
possible to eliminate a footnote by moving the text it contains to the main body ofthe article,
especially if the footnote is short and just adds extra details.
✗We randomly selected 24 individuals from each ofsix groups.1
[Footnote: 1. Groups 3,5, 11, 28, 30 and 34.]
✓We randomly selected 24 individuals from each ofsix groups (groups 3, 5, 11, 28, 30 and 34).
• Numbers in the text indicating footnotes should be superscripts (do not use parentheses,
punctuation or slash marks). Numbers for the notes themselves should be on the line and
followed by a full point.
•When a footnote is continued on the next page, there should be a hairline rule above it.Avoid
beginning a continued footnote with a full sentence, as this will make it look like a separate
footnote.
•If the first mention ofan abbreviation occurs in a footnote, it should be defined there.
UN D ER TA B L E S
Footnote links. Notes about the table as a whole can be left unlinked (i.e. no linking
letters/numbers/symbols) or linked to, for example, a relevant column heading. Notes about
specific parts ofthe table should be linked using superscript lower case letters (preferred),
superscript numbers or symbols (see Table 1 for examples). If lower case letters could be confused
with the table data, use symbols or numbers instead.Avoid the use of superscript numbers in
parentheses.
© 2007 John Wiley & Sons Ltd
23
![](asset-18.png)
If an abbreviation is mentioned for the first
time in a table (e.g.‘CE’in Table 1), it must be
defined in a footnote to that table.
Asterisk footnotes are reserved for probability
values in tables and usually signify the following
values: *,P≤0.05; **,P≤0.01; ***,P≤0.001.
The asterisk is often used in mathematics and
should therefore be avoided as a footnote
symbol.
Order
Footnote links within the table itself should
be ordered, according to first mention, across
columns by row (seea,b,cin Table 1).
The actual footnotes should appear in the
following order:
•source notes
•other general notes
•notes on specific parts ofthe table
(following the order in the table itself)
•notes on level of probability
1.11 Abbreviations
Keep the number of abbreviations in an article (particularly in the Abstract) to a minimum. If a
term is not used often, do not use its abbreviation: it will not help readers if they have to search
back through the article for its definition.
Use of abbreviations such as etc., i.e. and e.g.is best avoided in running text and is more suitable for
use with parentheses.
DE FINI N G ABBR E VIAT I O N S
Some abbreviations are so common that they do not need defining (e.g. DNA, PCR, d.f.).Whether
to spell out or not will depend on the subject matter ofyour journal.

Abbreviations are shortened forms of words or phrases.
Acronyms are abbreviations formed from the initial letter(s) of individual words in phrases. True acronyms
serve as pronouncable words (e.g. QANTAS, ANZAC, radar); others are technically called ‘initialisms’ (e.g.
ECG, LDL).
Contractions are abbreviations that include the first and last letters ofa word (e.g.Ltd)
Define all other abbreviations (term in full followed by abbreviation in parentheses) onfirst
mention in the Abstract, text, figure legends and table legends or footnotes; thereafter, use the
abbreviation only, except at the beginnings ofparagraphs (it is acceptable to use abbreviations at
the beginnings of sentences). If abbreviations are defined in an Abstract, they must beredefined at
first mention in the main body ofthe text. Do not define or use abbreviations in titles or headings.
When defining a series of abbreviations in legends, use commas and semicolons (e.g.Y, young; M,
middle-aged; O, old). Never use equals signs in definitions.
P U N C T U AT I O N
Full points
•Abbreviations that areall caps generally do not take full points (e.g. USA, NSW), but
abbreviations that are alllower case or end with a lower case letter do (e.g. i.v., b.i.d., Co., Ed.).
•When referring to authors by their initials,use full points and thin spaces [e.g.‘One of the
authors (D. M. D.)…’].
•Full points arenot used at the end ofcontractions (e.g. St, Mr, Dr, Natl, Figs, Ltd) in UK
English, but they are used in US English.
•When an abbreviation that takes a full point comes at the end ofa sentence, another full point
is not necessary.
Apostrophes
An apostrophe should not be used when an abbreviation is pluralized, but it can be used to indicate
possession.
F O R M AT T I N G
Roman type is generally used for scholarly Latin abbreviations (see below for some common
examples). The notable exception is et al., which is usually italicized.
There is no need to use capital letters in the full term (unless it is a proper name), even though the
abbreviation might be in capital letters.
N A M E S
Abbreviations should not be used for given names (e.g. William not Wm). When a person is
referred to by initials only (e.g. JFK), do not use full points. Titles should be spelt out before last
names (e.g.General Washington) but abbreviated before full names (e.g. Sen. Robert A. Taft).
‘Reverend’and ‘Honourable’are only spelt out when preceded by‘the’.‘Jr’and ‘Sr’ are set off by
commas after the name.
Agencies and organizations can be abbreviated in running text, in all caps with no periods (e.g.
NAACP). They should be defined at first mention as usual.

•In UK English,dates are given in the form 24 August 1964 (24/8/64). In US English,the form
August 24, 1964 (8/24/64) is used.
•Do not use ordinal numbers in dates (e.g.
1st, 11th, 22nd or 23rd). For year ranges, use
an en rule and do not elide (e.g.1995–1999
not 1995–99). Decades should be written as
e.g. 1960s not 1960’s or ’60’s.
•For centuries,use the form 18th century.

Key points
• Define all abbreviations (except very common ones such as DNA) at first mention in the
Abstract and again in the main text.
• Punctuate lower case (e.g.b.i.d.) but not upper case (e.g.USA) abbreviations.
•Do not use capitals in the full term (e.g.LSD stands for least significant difference).

1.13 Special Characters
Special characters are characters that arenot found on a conventional keyboard.These include

1.15 Currency
• Symbols (and abbreviations for non-US/UK
currencies) for units of currency generally
precede the figure (e.g. £58.00, $4580, €120,
EUR 350). The exceptions are those written in
full (e.g. 12 rupees). Use $ for $US unless other
dollar types are mentioned (e.g. $A, $HK).
•In book reviews etc., prices should be given
with values for the two decimal units after a
decimal point (e.g.$A38.00 not $A38).
•For ‘million’use ‘m’(e.g. £75m); for ‘billion’use ‘bn’ (e.g. £75bn). Note that ‘billion’ means ‘a
million million’ in UK English, but‘a thousand million’ in US English.
•Use whole figures and decimals consistently (e.g. $4.25 and $7.00, not $4.25 and $7).
•The following EU countries are now using the euro (former currency in parentheses): Austria
(schilling), Belgium (franc), Finland (markkaa), France (franc), Germany (mark), Greece
(drachma),Ireland (punt), Italy (lira), Luxembourg (franc), the Netherlands (guilder),
Portugal (escudo) and Spain (peseta).
1.16 Qualifications

1 Academic qualifications, in ascending order (e.g.BA MA PhD)
2 Professional qualifications (e.g.RN RM)
3 Honorary/fellowship qualifications (e.g. FAAN OBE)
Note that some qualifications automatically supersede others (e.g.to be a fellow ofa college you
must already be a member,so there is no point in putting MRCP if someone is also FRCP).

•North-west, south-southeast, etc. should beabbreviated if used extensively, particularly if
used as part ofa compound adjective (e.g.SW-facing slope,NNE-trending escarpment). Note
that north–south comes before east–west in the abbreviations.
• Adjectives using north, south, east or west take the forms north-east, north-eastern, northerly,
northeasterly, northward and northernmost.
L A TI T UD E AND LONG I T U DE
Use the form 44º56´N, 71º45´E (north–south first then east–west). There is no reason to use the
abbreviations ‘lat.’ and ‘long.’ in front ofthe coordinates because the compass directions show
which ofthe two is being given. Coordinates are usually given with an altitude (not elevation),
which should be given in metres above sea level (m a.s.l.).

UK GRID R EFE REN CES
Use the form‘NZ 684 018’.
C O U N T R I E S
•Avoid the terms America and North America unless it is clear that the continent is being
referred to; otherwise, use USA (always abbreviate; do not use U.S.A. or the States). US is used
as the adjectival form ofUSA (e.g.‘US aircraft carriers stationed in the Persian Gulf’).
•Use UK (always abbreviate).Note that UK = Great Britain plus Northern Ireland; Great
Britain = England, Scotland and Wales; the British Isles = UK plus the Irish Republic. UK can
be used as an adjective (e.g.‘UK harrier jets flying over the Falkland Islands’).
•Use the Netherlands not The Netherlands (although a capital Tis usually used in addresses –
this rule also applies for the Phillipines) orHolland (a region).
• Republics. Use China not People’s Republic of China/PRC (and Taiwan not Republic of
China); Korea not Republic of Korea/ROK; Germany not Federal Republic of Germany/FRG;
Ireland not Republic of Ireland (nor Eire); South Africa not Republic ofSouth Africa/RSA.
• Other. Use Russia,the Ukraine, Belarus, Georgia, Latvia, Lithuania, Estonia, etc., not the USSR
(use the former USSR if countries are not specified).Use the Czech Republic and Slovakia, not
Czechoslovakia. Use Bosnia and Herzegovina,Croatia, Serbia and Montenegro,and Slovenia
(or the former Yugoslavia if in doubt). Check the latest edition ofan atlas to confirm any recent
changes.
AU T HO R AD DRESS E S
Institutes,street names, etc. are better given in the native tongue ofthe author (e.g.Université de
Lyon should be preferred toLyon University,and Universität München to Munich University).
However, the names ofcities and countries should be given in the language in which the paper is to
be published.
C A P I T A L I Z A T I O N
•Use initial caps for e.g.Western Australia,South West Africa and Northern Ireland (proper
names) but not for e.g.southern Scotland or eastern India (descriptive terms).
•When climates or regions are described using an adjective that is a proper name, the name is
capitalized (e.g.Mediterranean climate, Alpine region, sub-Saharan desert).
•Northern Hemisphere, Southern Hemisphere (caps).
MI S CELLA NEO US PO I NTS
•Use Asia–Pacific (en rule; not Asian-Pacific) and South-East Asia (initial caps; hyphen).
•Use Island(s) (do not abbreviate toIs.) and River(s) (do not abbreviate toRiv.).
•Use Mount (not Mt). Note that ‘yama’,‘dake’ and several other suffixes mean mountain in
Japanese; however, they should not be removed from the name unless it has been anglicized;
check with the author or leave as supplied (e.g. Mount Tanakami-yama but Mount Fuji).

•For consistency and ease of reading, always type URLs and email addresses in lower case
letters (e.g. www.blackwellpublishing.com; person@wiley.com). Both URLs and email
addresses are case-insensitive, but there is a clear international trend to present both in
all lower case text. In many other electronic contexts (e.g.Web searches),a capital letter
represents only the capital letter, whereas the lower case letter represents both, so it seems
sensible to retain the distinction for URLs and email addresses.
•There may beexceptions when the capitals have been used extensively in branding a website
(e.g. www.GastroHep.com).
PREF E R RE D ADDR E SSES
•‘http://’is needed in URLs in articles so that the link becomes live on Wiley InterScience.
•The ScholarOne Manuscripts URLs do not start with ‘www’, so the URL should be written in full;
e.g. http://mc.manuscriptcentral.com/ejn
•The ‘www’part ofa URL doesn’t appear at the start of all Web addresses,so when writing a
URL that does start with ‘www’, it cannot be left out.
•There are a few variants ofthe Companywebsite URLs, but the preferred versions are as
follows:
www.wiley.com
www.blackwellpublishing.com
www.blackwellpublishing.com/<journal acronym>
www3.interscience.wiley.com/
BR E A K IN G A UR L
•When a URL must be broken over a line in a printed work, breaking after a slash or double
slash is preferable.
•Try not to break after a dot, leaving the dot at the end ofthe line of text. Do not use hyphens to
break long words at the end ofa line.
•A hyphen within a URL shouldn’t appear at the end ofa line.
SET TI NG O FF URLS F RO M SU RROUN DING T EX T
•Do not set off URLs with angle brackets, because angle brackets are used in some markup

2.1 Electronic Submission
P R E PA R AT I ON OF EL E C TR ON I C A RT W O R K
•Authors should be asked tosubmit EPS (line art) or TIFF (half-tone/photographs) files only.
•For scanned images, the scanning resolution(at final image size) should be as follows to
ensure adequate reproduction: > 800 dots per inch (d.p.i.) for line art; > 300 d.p.i. for half-
tones; > 600 d.p.i. for figures containing both half-tone and line images.
•EPS files should be saved with fonts embedded (and with a TIFF preview if possible).
• Black and whiteimages should be supplied as grayscale.
• Colour images should be supplied as CMYK, not RGB.
• Multipart figures should be supplied in the final layout in one file.
•For further details, see http://www.blackwellpublishing.com/bauthor/digill.asp
•The following artwork packages give suitable quality formats when dealing with electronic
artwork and allow you to‘save as’ or ‘export’ as TIFF and EPS, the preferred standardized
formats:
Adobe Illustrator 7.0 and above (EPS)
Adobe Illustrator 9.0 (EPS; also export as TIFF)
CorelDRAW 7.0 and above (EPS)
Deneba Canvas 6.0 and above (EPS)
Adobe Photoshop 4.0 and above (TIFF)
2.2 Disks
• CDs and floppy disks are both OK, but there is no current facility to process optical disks.
•Any word-processing format can be handled.
•The author must check that the final version of the hard copy and the file on the disk are the
same.
2.3 Artwork
There are many journal-specific requirements for artwork, so refer to your journal style sheet and,
if necessary, the ‘Instructions for Authors’guidelines (usually on the inside back cover of the
journal). See ‘Electronic Submission’ for information on electronic artwork.
GE NE RA L C H EC K L I ST
•Do the figures match the legends?
•What level of intervention is appropriate for figures in this journal? (There is always a ‘cost
versus quality’trade-off.)
•What reductionis appropriate for the figure? Consider (1) the size of any lettering and line
art, and (2) the column width ofthe journal.

![](asset-23.png)
•Do you need to add (a),(b),etc. to the various parts ofthe figure?
•Is the text in the figurelegible and error-free?
•Do anytints,areas of shading, etc. have to be redrawn? After reproduction, fine tints may
become solid black, and light shading may disappear.A crude way to check whether this could
be a problem is to photocopy the figure at the appropriate reduction.
•Is the figure to be processed as colour? If so, special attention needs to be paid to the authors’
and editor’s requirements as money is often involved! There is a requirement in some journals
to minimize colour – please consult the Wiley-Blackwell production editor if you are unsure
whether or not colour is acceptable.
2.4 Tables
WHE N IS A TAB L E NOT A TA B L E ?
Atable concisely presents numerical or factual information in a grid format. A table usually
contains at least two rows (including the column headings) and two columns; otherwise the
information may be better presented as a list.A ‘table’containing graphics (e.g. arrows in a
flowchart) is probably better treated as a figure, although occasionally figures may be embedded in
tables (e.g. chemical structures); in this case, alert the typesetter to the fact that graphics need to be
dropped into the table.
F O R M AT T I N G
•Make sure column headings arealigned (using tabs) with the entries below them.
•The first word ofan entry should normally have an initial capital.
•Complex tables may benefit from extra spaces between groups of rows (see example overleaf).
E D I T I N G
•The table legend should usually be treated as a title,and should stand on its own as a
description ofthe content. It should contain only a brief, general description of what is shown
in the table. Details about methods, statistics and specific parts ofthe table (e.g.‘Standard
errors are given in parentheses’) should be confined to footnotes.
• Units should be given in column headings, rather than repeated for every entry in the body of
the table.
•Define anyabbreviations in a footnote.
•See‘Footnotes’ (1.10) for how to deal with table footnotes.
•Make sure that rules in hierarchical column headings are correct (i.e. that they span the
appropriate text).
•In the column or row headings, authors sometimes neglect to include the top level of the
hierarchy (i.e.they do not tell you what the numbers in the table actually are!).You may find
that this information has been included in the legend (e.g.‘leaf dry weight’in the example
table overleaf).

2.5 References
Check your journal style sheet for how to style references in the list and their citations in the text.
In general, there are two main systems, Harvard and Vancouver, although there are some hybrids
with features ofboth styles (e.g. alphabetical Vancouver).
H A R VA R D
Citations in the text take the form ofauthor names and dates (e.g. Smith et al. 1990), and
references in the list are sorted alphabetically byauthor name.
In the text
Sort references in the text chronologically (e.g. Smith 1990; Jones 1995), and then alphabetically
within dates (e.g.Smith 1990; Brown 2001; Walton 2001).
For references with three or more authors,use the first author’s name and ‘et al.’ in the text (e.g.
Smith et al. 1990).
In the list
Sort references in the list alphabetically by first author, then bynumber of authors (one; two; three
or more), then chronologically within the one-author group,alphabetically within the two-author
group, and chronologically within the ≥three-author group:
Smedley, P. (2002)
Smith, G. (1983)
Smith, G. (2001)
Smith, G. and Jones, B.N. (1997)
Smith, G. and Stevens, D. (1996)
Smith, G., Wheeler, A., Lawrie, S. and von Hoffman, C. (1992)
Smith, G., McDonald, D.W. and Jones, B.N. (1994)
If two or more references have the same first author and date,you must use ‘a’,‘b’, etc.after the date
to distinguish them (e.g.Smith et al. 1990a). NB For two-author references, you need only do this if
both authors are the same.
Lower case particles are listed under the letter ofthe name proper but upper case particles under
the letter ofthe particle (e.g.da Silva under ‘S’ but Von Trapp under ‘V’).
VA N C O U V E R
•In straight Vancouver, references are numbered sequentially as they occur in the text.
Citations in the text take the form of superscript or parenthetical numbers,which refer the
reader to the references in the list. References in the list are ordered according to these
numbers.
•In alphabetical Vancouver,the references are ordered alphabetically in the list and then
numbered,and it is these numbers that appear in the text (so they will be out ofsequence in
the text; e.g. reference 51 might come before reference 6).
© 2007 John Wiley & Sons Ltd
37
In the text
Reference numbers are set as superscripts or within brackets (usually square brackets), depending
on the journal style. Superscripts should appear after,1and square brackets within [1],
punctuation. Use en rules for ranges; e.g. [1,2,3,4] becomes [1–4] and 24,25,26 becomes 24–26.

2.7 Permissions
•Authors must have written permission to reproduce figures, tables or any other material from
another source.This also applies todata from which a figure or table has been produced. If
you suspect that an author has taken material from another source, but either has not
acknowledged this or has supplied incomplete information, add a query (we assume that
authors have followed their responsibility to seek permission – refer them to our Copyright
Assignment Form).
• Acknowledge sources in figure and table legends in the format ‘Reproduced from Smith et al.
(1990), with permission from Mercat Press’. Some publishers may require the use of a
particular copyright line. Make sure that there is a reference to the source ofthe material – ask
the author to supply one if there is not.
• Photographs of equipment or company products should be checked for reference to the
manufacturer. It may be necessary to obtain permission for their use, particularly if the
product is referred to in a negative light.
2.8 Appendices
Appendices contain extra material (usually tables, lists, equations or lengthy sections of text) and
should be placed at the very end ofthe article.
•The style of appendices varies from journal to journal, but generally they are headed e.g.
‘Appendix 1’ and cited in the main body ofthe text as you would cite a figure or table.
Equations in appendices are numbered separately (e.g. Eqn A1, etc.).
•An appendix may have its own reference list.
•Supporting information (in the online publication) is now replacing appendices in many
journals.

3.1 Scientific Names
The scientific name ofa species is known as a binomen (zoology) orbinomial (botany). There are
differences in the naming conventions of animals, plants, bacteria and viruses (seeScientific Style
and Format for detailed naming conventions and style for each kingdom, or the individual codes –
listed below),but below are the basic guidelines.
International Code ofZoological Nomenclature
International Code ofBotanical Nomenclature
International Code of Nomenclature for Cultivated Plants
International Code of Nomenclature of Bacteria
International Code of Virus Classification and Nomenclature
• Genus and species names are presented in italics (e.g.Caenorhabditis elegans) and they have
singular endings. Higher taxa (i.e.family, order, class, phylum and kingdom) are set in roman
type with an initial capital (e.g. Coleoptera,
Insecta and Rosaceae). These taxa have plural
endings.
• Modifiers to species names are presented in
roman after the species name and are always
abbreviated.
•Spell outgenus and species names in full at
the first citation in the Abstract and text
(e.g. Bufo marinus); abbreviate genus names thereafter (e.g.B. marinus – note the full point
and thin space after the abbreviated genus name). However, use the full name at the start of
paragraphs, in tables, and whenever there could be ambiguity if the abbreviated name is used.
If two genera with the same initial letter are referred to, it may be beneficial to use partial
genus abbreviations (e.g.Picea abies ➝Pi. abies and Pinus sylvestris ➝P. sylvestris;
Staph. aureus and Strep. faecalis). Alternatively, use the full name to make it clear which genus
each species belongs to. If a new species ofthe same genus as another, already cited species is
introduced,the full name ofthe new species (i.e. repeat the genus name) should be given at its
first citation (e.g. if Xenopus laevis has already been named, you still need to spell outXenopus
at the first mention ofXenopus tropicalis).
•Adjectives and nouns derived from genus names become roman with a lower case initial (e.g.
Felis ➝feline, Libellula ➝libellulids, Streptococcus ➝streptococcal infection).Those derived
from higher taxonomic groups also begin with a lower case letter and are presented in roman
(e.g. Ostracoda ➝ostracods, Cactaceae ➝cacti).
•A scientific name given at its first mention after a vernacular name should be separated from
it by a comma if the two names are exact synonyms (e.g.…the two-spotted cricket, Gryllus
bimaculatus,…) but not if the vernacular name may apply to more than one species (e.g.the
starfish Asterina pectinifera,the medaka Oryzias latipes).
•The genus name is sometimes referred toalone,even in titles (e.g.Xenopus, Asterina), but the
species name cannot be (laevis, pectinifera). Species within a genus can be referred to in
general terms by the abbreviations sp.(singular) or spp. (plural) after the genus name (e.g.
Xenopus sp.).

A U T H O R I T I E S
The ‘authority’of a scientific name is the name ofthe personwho originally classified the species.
It is particularly important to include the authority if there is some controversy about the
classification.
•The authority should be given at first
mention of the species,set in roman after
the scientific name (e.g.Anthomyza elbergi
Andersson).Alternatively, a reference
may be cited.
•If a date of classification is given with the
authority, it should be separated from the
authority by a comma (e.g.Anthomyza bellatrix Roháçek, 1984).
•When a species or subspecies is transferred to a genus other than that in which it was first
classified, the original authority is placed in parentheses. In botany and microbiology, the
authority ofthe new combination follows and is not placed in parentheses [e.g.Calluna
vulgaris (L.) Hull, Shigella dysenteriae (Shiga) Castellani & Chalmers]. In zoology, the
authority ofthe new combination is not given [e.g.Lepomis gulosus (Cuvier)].
BA C T E R IA NA MES
•Names ofall bacterial taxa areitalicized [e.g. Pseudomonadales (order),Pseudomonadaceae
(family), Pseudomonas (genus), etc.].
•Some organisms that cannot be differentiated taxonomically at the level of subspecies are
given the infrasubspecific designations pathovars (pv.), biovars (b.), serovars (sv.), phagovars,
chemovars and morphovars.
• Vernacular names ofbacteria are always set in roman lower case (e.g. mycobacteria,
salmonella, klebsiellae).
VIR US NAM ES
•Virus names end in virales (order), viridae (family) virinae (subfamily) and virus (genus).
They donot follow normal binomial naming.
• Approved (by the International Committee on Taxonomy of Viruses) international names for
orders, families, subfamilies and genera are set in italics with initial capitalization. The name
of the taxon should precede the term in formal use (e.g.the familyParamyxoviridae,the genus
Orthopoxvirus).
•Names that have not yet been approved and vernacular names are set in lower case roman
(e.g. maize dwarfmosaic virus,herpes simplex virus type I, rhabdovirus,yellow fever virus).
Virus names are also set in roman when used in an adjectival form. Be careful not to jump
hierarchical levels in vernacular usage (because it is not always easy to identify which level is
being referred to): add taxon identification wherever needed.
•The first letter of a proper noun or proper adjectiveincorporated into the name ofa virus is
capitalized (e.g.West Nile virus). If part ofthe vernacular name incorporates a Latin name,
the Latin name is capitalized and italicized.

Names oforganisms should be given in full, i.e. common name and Latin name with authority,
when cited for the first time.Latin names should be given in italics.
Use ofparentheses in scientific names follows strict protocols, and generally what is supplied will

•The order ofbrackets should be <{[( )]}>.
•If an equation (displayed) runs over more than one line, line breaks should occur before a
relational sign (i.e. =, >, ⊃,∉,∝, etc.). The turnover line should then be aligned with previous
relational signs. Breaks can also occur before operational signs (i.e. +, –, ±, ×,÷,∑, etc.); the
turnover line then aligns to the right ofthe relational sign.
•Operational and relational signs have fixed thin spaces on either side ofthem (e.g.x+y).
• Fractions in run-on equations can be represented by use ofa solidus [e.g.x/(y+1)] to prevent
disruption to the line oftext above. Parentheses often need to be added when converting
fractions to the solidus form.
•The radical (root sign) is set using the symbol (√) or a superscript index (–1/2), rather than
taking a line (vinculum) across the whole equation. This is most important in run-on
equations to prevent disruption to the line of text above.

In general, use units based onenergy for heat or energy balance; use units based onphotons for
photochemical processes such as photosynthesis or photomorphogenesis.The waveband over
which measurements are made should be specified [e.g. energy fluence rate (irradiance) of
650 W m–2 over the waveband 300–1000 nm; photosynthetic photon fluence rate (PPFR) of
720 µmol m–2 s–1 over the waveband 400–700 nm].
