The rapid pace of environmental change in the Anthropocene necessitates the development
of a new suite of tools for measuring ecosystem dynamics. Sentinel species can provide …

About 62,000 dead or dying common murres (Uria aalge), the trophically dominant fish-
eating seabird of the North Pacific, washed ashore between summer 2015 and spring 2016 …

During the Pacific marine heatwave of 2014–2016, abundance and quality of several key
forage fish species in the Gulf of Alaska were simultaneously reduced throughout the …

Mercury (Hg) is a natural trace element found in high concentrations in top predators,
including Arctic seabirds. Most current knowledge about Hg concentrations in Arctic …

Acute anomalous ocean warming events, including marine heatwaves (MHWs), have
significant effects on reproduction and survival of piscivorous seabirds. Additionally, MHWs …

Climatic factors drive changes in forage fish communities and may influence the productivity
of piscivorous predators, but specific mechanisms of response remain poorly known …

Legacy persistent organic pollutants (POPs), such as organochlorine pesticides (OCs) and
polychlorinated biphenyls (PCBs), are known to persist in the marine environment; however …

Multi-colony studies of breeding seabirds may provide insights into the mechanistic links
between large-scale climate variability and local changes in prey availability. In the North …

The foraging ecology of breeding seabirds is largely influenced by prey availability and
energy demands related to reproduction which, in combination with other factors, can affect …

Ecological theory predicts that closely related species can coexist if they segregate in space,
time, or diet to reduce competitive overlap when resources are limited. These differences in …
