Temporal scales of foraging in a marine predator
Read more of: Temporal scales of foraging in a marine predatorThe pattern of prey distribution can profoundly affect the foraging behavior and success of a predator. In pelagic marine ecosystems, where prey is often patchily distributed, predators must be able […]

Individual variation in the duration of pregnancy and birth date in Antarctic fur seals: the role of environment, age, and sex of fetus
Read more of: Individual variation in the duration of pregnancy and birth date in Antarctic fur seals: the role of environment, age, and sex of fetusThe duration of 506 pregnancies in Antarctic fur seals (Arctocephalus gazelld) was measured 1983–1993. On average, pregnancy lasted 359 days, with a range of 340–390 days, representing 20% of the […]
