Modified from the Animal Behaviour writing guidelines.
Scientific Integrity
Animal Behaviour publishes papers by scientists conducting
research at locations around the globe. Publication is, therefore, based upon
mutual trust between publisher and authors. Professional integrity in the
conduct and reporting of research is an absolute requirement as is a
willingness to share information with other members of the scientific
community. Consequently, as a condition of publication in Animal Behaviour, authors must agree both to honour any reasonable request for materials or methods
needed to verify or replicate experiments reported in the journal and to make
available, upon request, any data sets upon which published studies are based.
Students failing to meet ethical standards of science can face failing grades
in the course for which the work is presented.
Instructions for
Authors
Animal Welfare
If
ethical considerations arose in the course of the study, the author should
describe in the manuscript (see Methods) how those considerations were
addressed. For example, information needs to be provided on the following
areas: housing and general maintenance, disposal of animals including release
of wild-caught animals, culling of litters, techniques causing desertion,
aggression, predation, use of live animals as food, parasitism, techniques or
manipulations (e.g. physiological, pharmacological, genetic, blood and tissue
sampling, use of anaesthetics and restraints, plumage
alterations), trapping, marking, radiotagging, food
or water deprivation, manipulation of diets and access to food, social
deprivation, brood manipulations, environmental manipulations, conservation
implications, details of licenses/permissions obtained for the study. If
authors fail to include relevant information, we shall request a revision and
resubmission of the paper. In exceptional cases, where unresolved ethical
questions remain, the manuscript may be sent to review by the Institutional
Animal Care and Use Committee. In such cases, the decision as to whether the
manuscript is accepted for publication remains with the Editor or, in the final
instance, the Executive Editor.
Formatting of Text
Headings
Headings
in the body of the manuscript should be brief. The usual main headings for
Research papers are: Methods, Results, Discussion, Acknowledgments and
References (Introduction is not used). Papers should not be forced to fit into
this pattern of headings, however, if they do not naturally do so. Type main
headings in capitals on a separate line and centre them on the page (note that
Commentaries and Forum articles lack this heading type). Type subheadings at
the left of the page and on a separate line, and begin the main words with a
capital letter. Start sub-subheadings on a new line, aligned full left, and underline
them. Start the text on a new line after subheadings and sub-subheadings. When
presenting multiple experiments, authors may use main headings for the titles
of each experiment, with the Methods and Results of each experiment listed as
subheadings. Try to keep subheadings short enough to fit within a single
column.
Parts of the Manuscript
Arrange
manuscripts in the following order: title page, abstract, text,
acknowledgments, references, appendices, tables, figure legends, figures.
Title page
The
title page must include the following information.
Abstract
The
Abstract should describe the purpose of the study, outline the major findings
and state the main conclusions. It should be concise, informative, explicit and
intelligible without reference to the text. Abstracts should usually be limited
to 250 words. Use both common and scientific names of animals at first mention
in the Abstract unless they are given in the title. Avoid using references; if
used, give the journal name, volume and page numbers.
Introduction
The
Introduction should be brief, not normally exceeding two manuscript pages. It
should explicitly state the aims of the study and place it within the context
of existing work. Keep references to a minimum by citing reviews rather than
primary research papers where appropriate.
Methods
The
Methods should be sufficiently detailed to allow someone else to replicate the
study. Repetition of methodological details can sometimes be avoided by
referring to previous studies, however. Give the names and addresses of
companies providing trademarked products. Always state sample sizes (the number
of animals used in the study) and the age, sex, breed/strain and source of animals.
Full details of testing or observational regimes should be given. If captive
animals were used, include details of housing conditions relevant to the study
(e.g. cage size and type, bedding, group size and composition, lighting,
temperature, ambient noise conditions, maintenance diets) both during the study
and during any period before the study that might bear on the results. The
Methods section may also contain a description of the kinds of statistics used
and the activities that were recorded.
Results
This
section should include only results that are relevant to the hypotheses
outlined in the Introduction and considered in the Discussion. The text should
complement material given in Tables or Figures but should not directly repeat
it. Give full details of statistical analysis either in the text or in Tables
or Figure legends. Include the type of test, the precise data to which it was
applied, the value of the relevant statistic, the sample size and/or degrees of
freedom, and the probability level. Number Tables and Figures in the order to
which they are referred in the text.
Discussion
It
is often helpful to begin the Discussion with a summary of the main results.
The main purpose of the Discussion, however, is to comment on the significance
of the results and set them in the context of previous work. The Discussion
should be concise and not excessively speculative, and references should be
kept to a minimum by citing review articles as much as possible.
References
For
references in the text, give full surnames for papers by one or two authors,
but only the surname of the first author, followed by 'et al.' for three or
more (note that 'et al.' is not underlined). Check that all references in the
text are in the reference list and vice versa, that their dates and spellings
match, and that complete bibliographical details are given, including page
numbers, names of editors, name of publisher and full place of publication if
the article is published in a book. Check foreign language references
particularly carefully for accuracy of diacritical marks such as accents and
umlauts.
Cite
references in the text as, for example, Fagen &
Young (1978) or, if in parentheses, as (Murton 1963).
Do not use commas to separate the author's name from the date. Use lower-case
letters to distinguish between two papers by the same authors in the same year
(e.g. Packer 1979a). List multiple citations in chronological order (e.g. Zahavi 1972; Halliday 1978;
Arnold 1981a, b), using a semicolon to separate each reference. Cite references
in the reference list in alphabetical, and then chronological, order according
to the authors' surname and date. To help readers locate 'et al.' citations
with the same first authors in the reference list, list references with three
(or more) names after those with two, by date, as in the following sequence:
Marin
& Silva 1992
Marin,
Silva & Lopez 1986

Because
of the ephemeral nature of many Web sites, other Web citations will be reviewed
by the Editors to ensure they are appropriate.
For
papers in the course of publication, use 'in press' to replace the date and
give the journal name in the references. Cite unpublished manuscripts
(including those in preparation or submitted), talks and abstracts of talks in
the text as 'unpublished data' following a list of all authors' initials and
surnames. Do not include these in the reference list.
Digital Object Identifiers
To
facilitate cross-referencing of articles on the Web, the digital object
identifier (DOI) for papers in Elsevier journals will now be included in their
reference citation as follows:
Bradbury, J. W. & Vehrencamp,
S. L.
In press. Economic models of animal communication. Animal
Behaviour, doi:
10.1006/anbe.1999.1330.
Jirotkul, M. 1999. Population density influences
male-male competition in guppies. Animal Behaviour,
58, 1169-1175. doi:
10.1006/anbe.1999.1248.
The
DOI of a cited paper can be found at the top of its title page. If authors are
aware of a paper's DOI, it would be helpful if they could include it in their
citation list.
Tables
Keep
Tables as simple as possible and make them understandable without reference to
the text. Type each table on a separate page. In addition:
Figures
Electronic supplementary material
Material
that aids in the understanding or clarification of the printed article, such as
video clips (AVI or MPEG), colour photographs (GIF or
JPEG), sound recordings (WAV), or large data tables, may be provided to the
professor with electronic access details provided in the text. The material
will be considered to be part of a manuscript and will be reviewed as such.
Footnotes
Use
footnotes only to add information below the body of a Table.
Numerals
Write
numbers of 10 or more as numerals except at the beginning of a sentence. Write
the numbers one to nine in words, unless they precede units of measure or are
used as designators. Quote times of day using the 24-hour clock without a break
or point in the middle and followed by 'hours'; e.g. '1515 hours'. Give years
in full; e.g. '1986-1987' and dates as
Abbreviations
Units
and abbreviations should conform to the Systeme
International d'Unites. Avoid acronyms.
Statistical conventions
Means
and standard errors/standard deviations (and medians and interquartile
ranges/confidence limits), with their associated sample sizes, are given in the
format X
SE = 10.20
1.01 g, N
= 15, not X = 10.20, SE = 1.01, N = 15.
For
significance tests, give the name of the test followed by a colon, the test
statistic and its value, the degrees of freedom or sample size (whichever is
the convention for the test) and the P value (note that F values
have two degrees of freedom). The different parts of the statistical quotation
are separated by a comma.
If
the test statistic is conventionally quoted with degrees of freedom, these are
presented as a subscript to the test statistic. For example:
ANOVA:
F1,11 = 7.89, P = 0.017
Kruskal-Wallis test: H11 = 287.8, P
= 0.001
Chi-square
test: x22 = 0.19, P=0.91
Paired
t test: t12 = 1.99, P=0.07
If
the test is conventionally quoted with the sample size, this should follow the
test statistic value. For example:
Spearman
rank correlation: rS = 0.80, N = 11, P
0.01
Wilcoxon signed-ranks test: T = 6, N = 14, P < 0.01
Mann-Whitney
U test: U = 74, N1 = N2 = 17,
P < 0.02
P values for significant outcomes can be quoted as below a
threshold significance value (e.g. P < 0.05, 0.01, 0.001), but
wherever possible should be quoted as an exact probability value. Departure
from a significance threshold of 0.05 should be stated and justified in the
Methods. Nonsignificant outcomes should be indicated
with an exact probability value, not as NS or P
0.05. Marginally
nonsignificant outcomes can be indicated as exact
probability values or as P < 0.1.
State whether a test is one tailed or two tailed (or specific or nonspecific in
the case of Meddis' nonparametric ANOVAs). One-tailed
(or specific) tests should be used with caution. Their use is justified only
when there are strong a priori reasons for predicting the direction of a
difference or trend and results in the opposite direction can reasonably be
regarded as equivalent to no difference or trend at all. Authors are referred
to Kimmel (1957, Psychological Bulletin, 54, 315-353).
Do
not quote decimals with naked points, for example quote 0.01, not .01, or
normally to more than three decimal places (the exception being P values
for significance tests, which may be quoted to four decimal places where
appropriate, e.g. 0.0001).
Regressions and analyses of variance. The significance of
regressions should be tested with F or t but not the correlation
coefficient r. R2 should be quoted with both regressions and
parametric analyses of variance.
Multiple range tests. Unplanned multiple
range tests following ANOVA should be avoided unless their appropriateness for
the comparisons in question is verified explicitly. Authors are referred to the
review by Day & Quinn (1989, Ecological Monographs, 59, 433-463).
Power tests. Where a significance test based on a small
sample size yields a nonsignificant result, explicit
consideration should be given to the power of the data for accepting the null
hypothesis. Authors are referred to Thomas & Juanes
(1996, Animal Behaviour, 52, 856-859) and Colegrave & Ruxton (2003, Behavioral
Ecology, 14, 446-447) for guidance on the appropriate use of power tests.
Providing a value for power based on a priori tests is preferred. Values of
observed power are not appropriate. Authors should consider effect sizes and
their confidence intervals in drawing conclusions regarding the null
hypothesis.
Transformations. Where data have been transformed for
parametric significance tests, the nature of the transformation and the reason
for its selection (e.g. log x, x2, arcsine) should be stated.
