What is included in the 2500 word limit?
Biology Letters considers articles of up to 2500 words including all text (references, legends, acknowledgements, cover page etc) and up to 4 displays (ie figures and tables), of which no more than 2 should be figures. This would be equivalent to four published journal pages. Authors have the option to include electronic supplementary material, such as additional figures or datasets. However, the article should stand alone. Electronic supplementary material should not exceed 10Mb, and should be submitted along with the main article via our online submission system.
