Submissions

Author Guidelines

Manuscripts must not previously have been published or offered simultaneously elsewhere. All authors must have read and approved the manuscript. Submissions are done by the electronic submission system. In case of problems, please contact the editor (arild.johnsen@nhm.uio.no).

Both pages and lines should be numbered consecutively. Separate pages should be used for (1) title page with name(s) and full postal and e-mail address(es) of the author(s), and a suggestion for a running head and up to five keywords, (2) abstract, (3) text, (4) references, (5) tables with headings, (6) figure legends, (7) numbered figures. The approximate position of tables and figures in the text should be indicated in the margin. The body of the article should be organized in sections labelled Introduction, Materials and Methods, Results, Discussion, Acknowledgements, and References.  

Short communications need not be subdivided into sections, but must include an abstract.

Cite each figure and table in the text. Tables and figures must be sequenced in the order cited. Use “Figure” and “Table”, not “Fig.” and “Tab.”

Dating and time, use: e.g. 20 January 2004; the 24-hour clock: e.g. 07:00 and 22:00. Proper names of birds should be capitalized, but not the English names of other organisms. Use the following abbreviations: s (second), min (minute), h (hour), designate temperature as °C. Do not abbreviate day, week, month, year.

Use the following statistical abbreviations: ANOVA, SD, SE, df, CV, ns, n, p, r, rs, F, G, t-test, U-test. Write out numbers one to nine except for measurements (e.g. three birds, 4 mm, 5 min, 10 days). Use 30% instead of 30 percent.

Each reference cited in the text must be listed in the References section, and vice versa.

Cite literature in text as follows:

• One author: Haftorn (1971) or (Haftorn 1971).
• Two authors: Haftorn and Hailman (1990) or (Haftorn & Hailman 1990).
• Three or more authors: Aarvak et al. (1996) or (Aarvak et al. 1996).
• Work where author(s) name(s) and year are identical should be placed in the order when first mentioned in the text (e.g. 1990a, 1990b).
• Manuscripts that are accepted for publication but not yet published: Mortensen (in press) or Mortensen (2007) if date known.
• Unpublished materials: (Mortensen unpubl. data), (Mortensen pers. obs.), Mortensen  pers. comm.). Cite references in alphabetical order by first author’s name. References by a single author precede multiauthored works by same author, regardless of date.   

Citations should follow formats below
