The short-tailed albatross () is a threatened seabird whose present-day range encompasses much of the North Pacific. Within this species, there are two genetic clades (Clades 1 and 2) that...

Theory and field studies suggest that long-term individual foraging site fidelity (IFSF) may be an important adaptation to competition from increasing population. However, the driving mechanisms and extent of long-term ...

Fisheries encompass complex interplays between social, economic, and environmental factors, but limitations on historical fisheries data can hamper efforts to identify and contextualize the long-term spatiotemporal patterns that shape them....

Isotopic studies of archived fish scales have tremendous potential to develop long-term retrospectives that provide important insights into how humans have altered aquatic ecosystems. However, fish specimens in museum archives...

Rationale: Stable sulfur isotope compositions (δ S values) are a useful marker of terrestrial (lower δ S) versus marine (higher δ S) diets. In coastal areas, S-enriched sea spray can...

Lake Ontario once supported a large complex of Atlantic Salmon (Salmo salar) populations that became extinct prior to scientific study. Since the 1860s, research efforts to conserve and reintroduce a...

Rationale: Fish bone collagen isotopic measurements are increasingly important in palaeodietary and paleoenvironmental studies yet differences in the chemical and physical properties of fish relative to other vertebrate bones are...
