| postsealing genetic variation and population structure of two species of fur seal (arctocephalus gazella and a. tropicalis). | commercial sealing in the 18th and 19th centuries had a major impact on the antarctic and subantarctic fur seal populations (arctocephalus gazella and a. tropicalis) in the southern ocean. the intensive and unrestricted nature of the industry ensured substantial reductions in population sizes and resulted in both species becoming locally extinct at some sites. however, both species are continuing to recover, through the recolonization of islands across their former range and increasing populatio ... | 2000 | 10736028 |
| entanglement of antarctic fur seals at bouvetøya, southern ocean. | entanglements of antarctic fur seals arctocephalus gazella were recorded during four summers from 1996 to 2002 at the subantarctic island, bouvetøya. rates of entanglement varied between 0.024% and 0.059%. these rates are low for a pinniped population and might be because of the geographic isolation of the haulout site. an apparent decrease in the levels of entanglement over the course of the study was likely due, at least in part, to the removal of entanglements by observers. at least two-third ... | 2006 | 16797599 |
