Mechanisms of deaths in captive juvenile New Zealand fur seals (Arctocephalus forsteri).
Juvenile seals are sometimes encountered in waters around South Australia with injuries and/or diseases that require veterinary treatment. Two cases are reported where apparently stable animals died soon after being rescued due to quite disparate conditions. In Case 1 a juvenile male New Zealand fur seal (Arctocephalus forsteri) was found unexpectedly dead in its enclosure. A necropsy examinati...
متن کاملIdentification of a Novel Circular DNA Virus in New Zealand Fur Seal (Arctocephalus forsteri) Fecal Matter
Fur seal feces-associated circular DNA virus (FSfaCV) is a novel virus isolated from the fecal matter of New Zealand fur seals. FSfaCV has two main open reading frames in its 2,925-nucleotide (nt) genome. The replication-associated protein (Rep) of FSfaCV has similarity to Rep-like sequences in the Giardia intestinalis genome.

متن کاملTop-down and bottom-up influences on demographic rates of Antarctic fur seals Arctocephalus gazella.
Two major drivers in population dynamics are bottom-up processes, such as environmental factors that affect foraging success, and the top-down impacts of predation. Many populations of marine mammal and seabird species appear to be declining in response to reductions in prey associated with the bottom-up effects of climate change. However, predation, which usually occurs at sea and is difficult...
