Individual variability in seabird foraging and migration

In seabirds, individuals show remarkable variation in foraging and migration strategies due to a combination of intrinsic state and environmental conditions experienced. Technological advances in recent years have seen an explosion of studies tracking individuals for extended periods, enabling among- and within-individual variation to be quantified in unprecedented detail.  These studies are providing fundamental insights into key factors such as individual specialisation, plasticity in response to environmental change, seasonal carry-over effects, navigation, habitat connectivity and the genetic basis of behaviour. Quantifying the intrinsic and environmental factors underpinning individual variation in foraging and migration is critical for understanding population dynamics and implementing effective conservation programmes. This Theme Section will showcase the latest research in this fast moving field, using a range of approaches including bio-logging, experimental manipulations and advanced modelling. Anyone interested in submitting to the TS should contact Jacob González-Solís.

 

Editors: J. González-Solís, R. A. Phillips, F. Daunt, S. Lewis, R. Wilson
Deadline for ms submission: end of April




Individual Theme Section articles are published 'Advance View' as soon as they are ready. Once the Theme Section is completed, they will be fully published in a regular volume of MEPS and given a volume number and page range. Theme Section literature cites within the articles will also be updated.
