Journal ArticleDOI
Using stable isotopes to determine seabird trophic relationships
TL;DR: Stable isotopes of nitrogen and carbon analyses suggest that lower trophic-level organisms are more important to several seabirds than was recognized previously and may be a good indicator of inshore versus offshore feeding preference.
Journal ArticleDOI
Global Seabird Response to Forage Fish Depletion-One-Third for the Birds

TL;DR: A threshold in prey abundance is identified below which seabirds experience consistently reduced and more variable productivity and provides an indicator of the minimal forage fish biomass needed to sustain seabird productivity over the long term.
Journal ArticleDOI
Community reorganization in the Gulf of Alaska following ocean climate regime shift
Paul J. Anderson,John F. Piatt +1 more
TL;DR: A shift in ocean climate during the late 1970s triggered a reorganization of community structure in the Gulf of Alaska ecosystem, as evidenced in changing catch composi- tion on long-term (1953-1997) small-mesh trawl surveys.
Journal ArticleDOI
Dynamics of food availability, body condition and physiological stress response in breeding Black‐legged Kittiwakes
TL;DR: The results suggest that, in addition to a seasonal change in bird physiology during reproduction, local ecological factors such as food availability affect circulating levels of corticosterone and adrenal response to acute stress.
Journal ArticleDOI
Corticosterone facilitates begging and affects resource allocation in the black-legged kittiwake
TL;DR: Two functional implications are suggested of the increased corticosterone secretion during food shortages in the black-legged kittiwake: it facilitates begging in chicks, and it affects time allocated by parents to guarding young at the nest.
