Selection of prey that are small and in poor body condition is a widespread phenomenon in
terrestrial predator–prey systems and may benefit prey populations by removing …

Identifying factors determining the performance of individuals is an essential part of
resolving what drives population dynamics. For species undergoing ontogenetic shifts in …

Due to spatio-temporal variability of lower trophic-level productivity along the California
Current Ecosystem (CCE), predators must be capable of switching prey or foraging areas in …

Atlantic salmon are vulnerable to predators at every stage of their incredible life cycle. To
some extent, selective pressure by predators is likely to have played a role in the very …

Overfishing of predatory fish has contributed to an increase in forage-fish stocks. At the same
time, a rising demand for forage fish to supply fishmeal markets, in combination with climate …

Predator–prey interactions must be considered when aiming to enhance populations by
releasing artificially reared individuals into natural environments. Released individuals …

Parent birds must be able to recognize and provide for the energetic demands of their
chicks. In semiprecocial species, including many seabirds, the en-ergy requirements of …

Summary 1 We studied chick diet in a known‐age, sexed population of a long‐lived seabird,
the Brünnich's guillemot (Uria lomvia), over 15 years (N= 136; 1993–2007) and attached …

The response of marine predators to changes in fine-scale prey distribution is poorly
understood. Precipitous declines in marine apex predators necessitate a better …

Body size is a critical feature of the ecology of most organisms and has been used to
describe and understand predator–prey interactions in both terrestrial and aquatic …
