ESR Specials are integrated multiauthor syntheses initiated and coordinated by acknowledged experts. They highlight cutting-edge research areas or problems and/or bring together cogent bodies of literature on key taxa. Typically they are led by one or more members of the ESR Editorial Board, sometimes including Guest Editors. We welcome additional suggestions for Specials; contact ESR Editor in Chief, Prof. Brendan Godley.

Forensic methods have been used to trace the origin of marketed shark fins. Scalloped hammerhead sharks Sphyma lewini are particularly vulnerable to capture for the fin trade because of their predictable schooling behaviour, especially at seamounts. This photograph was taken at Cocos Island in the eastern Pacific.

Longhorn beetles Leptura maculata are individually marked with ink to study the population size and structure of the species. Population size is one of the key criteria for completing an IUCN Red List assessment, but baseline data are lacking for saproxylic insects (see Komonen et al. this Theme Section).

A gentoo penguin Pygoscelis papua in Antarctica equipped with a prototype ‘Daily Diary’ in 1992. This system, now hugely enhanced, provides details on travel routes, behaviour, energy expenditure and the environmental conditions encountered by free-living animals (see Wilson et al. this Theme Section)
