Determinants of individual foraging specialization in large marine vertebrates, the Antarctic and subantarctic fur seals
The degree of individual specialization in resource use differs widely among wild
populations where individuals range from fully generalized to highly specialized. This …

From video recordings to whisker stable isotopes: a critical evaluation of timescale in assessing individual foraging specialisation in Australian fur seals
Estimating the degree of individual specialisation is likely to be sensitive to the methods
used, as they record individuals' resource use over different time-periods. We combined …
