Pup Vibrissae Stable Isotopes Reveal Geographic Differences in Adult Female Southern Sea Lion Habitat Use during Gestation

Creator:

Baylis, Alastair M. M., Kowalski, Gabriele J., Voigt, Christian C., Orben, Rachael A., Trillmich, Fritz, Staniland, Iain J., and Hoffman, Joseph I.

Abstract:

Individuals within populations often differ substantially in habitat use, the ecological consequences of which can be far reaching. Stable isotope analysis provides a convenient and often cost effective means of indirectly assessing the habitat use of individuals that can yield valuable insights into the spatiotemporal distribution of foraging specialisations within...

Disentangling the cause of a catastrophic population decline in a large marine mammal

Creator:

Baylis, Alastair M. M., Orben, Rachael A., Arnould, John P. Y., Christiansen, Fredrik, Hays, Graeme C., and Staniland, Iain J.

Abstract:

Considerable uncertainties often surround the causes of long-term changes in population abundance. One striking example is the precipitous decline of southern sea lions (SSL; Otaria flavescens) at the Falkland Islands, from 80 555 pups in the mid 1930s to just 5506 pups in 1965. Despite an increase in SSL abundance over...
