Summary 1 Abundant mid‐trophic pelagic fish often play a central role in marine
ecosystems, both as links between zooplankton and top predators and as important fishery …

Climate regime shifts force fish communities through rapid transitions between alternate
species assemblages, but little is known about the role that biochemical ecology plays in …

A climatic regime shift during the mid-1970s in the North Pacific resulted in decreased
availability of lipid-rich fish to seabirds and was followed by a dramatic decline in number of …

In the relatively simple Baltic Sea ecosystem, zooplankton-feeding sprat Sprattus sprattus is
a major food source for breeding seabirds and piscivorous fish, and an important resource …

The junk-food hypothesis attributes declines in productivity of marine birds and mammals to
changes in the species of prey they consume and corresponding differences in nutritional …

We investigated the relative roles of bottom-up and top-down factors in limiting productivity
of an upper trophic level marine predator. Our primary working hypothesis was that the …

Disruption of natural food webs is becoming a commonplace occurrence as a result of
human activities. Considering this, there is a need to improve our ability to define food web …

Food availability comprises a complex interaction of factors that integrates abundance,
taxonomic composition, accessibility, and quality of the prey base. The relationship between …

Human activities affect all trophic levels of marine food webs and threaten numerous
species. The status of such populations can be assessed via monitoring of their size …

We assessed by using a bomb calorimeter the energy density of the main species of
Patagonian freshwater ecosystems, including fish, crustaceans, gastropods, oligochaetes …
