Molecular scatology as a tool to study diet: analysis of prey DNA in scats from captive Steller sea lions
TLDR
A captive feeding trial to test whether prey DNA could be reliably detected in scat samples from Steller sea lions highlighted an approach that can accurately identify prey species and is not dependent on prey hard parts surviving digestion. Expand
Historical and modern distribution and abundance of the New Zealand sea lion Phocarctos hookeri
TLDR
Although the authors have no direct estimate of pristine abundance, the present population size is clearly reduced and subsistence and commercial killing of sea lions is the most likely cause of historical changes in distribution and abundance. Expand
Population structure in an inshore cetacean revealed by microsatellite and mtDNA analysis: Bottlenose dolphins (Tursiops sp.) in Shark Bay, Western Australia
TLDR
The results indicate that dispersal in female dolphins in Shark Bay is more restricted than that of males, and analysis of genetic differentiation between sampling localities showed a pattern of isolation-by-distance. Expand
Summer diving behaviour of lactating New Zealand sea lions, Phocarctos hookeri
TLDR
The diving behaviour of 14 female New Zealand sea lions was recorded during early lactation in January and February 1995 on the Auckland Islands, New Zealand and showed no diel pattern overall. Expand
Studying Seabird Diet through Genetic Analysis of Faeces: A Case Study on Macaroni Penguins (Eudyptes chrysolophus)
TLDR
The ability of the DNA-based approach to detect temporal variation in the diet of macaroni penguins indicates this non-invasive method will be generally useful for monitoring population-level dietary trends in seabirds. Expand
Odontocete bycatch and depredation in longline fisheries: A review of available literature and of potential solutions
Operational interactions between odontocetes (i.e., toothed whales) and longline gear are a global phenomenon that may threaten the conservation of odontocete populations and the economic viabilityExpand
ENERGETICS OF A BENTHIC DIVER: SEASONAL FORAGING ECOLOGY OF THE AUSTRALIAN SEA LION, NEOPHOCA CINEREA
TLDR
The foraging behavior of Neophoca cinerea indicated that it works hard to exploit benthic habitats in the waters around its breeding site. Expand
Aerobic dive limit: how often does it occur in nature?
TLDR
It appears that benthic foraging requires these animals to reach or exceed their aerobic dive limit, similar to how two sea lions forage on the benthos while the fur seals feed shallow in the water column. Expand
Winter habitat use and foraging behavior of crabeater seals along the Western Antarctic Peninsula
We quantified the winter and spring movement patterns and foraging behavior of adult crabeater seals (Lobodon carcinophagus), and the influence of sea ice and bathymetry on their foraging behavior.Expand
Abundance, distribution and status of the New Zealand sea lion, Phocarctos hookeri
TLDR
The abundance of the New Zealand sea lion, Phocarctos hookeri, was estimated using a model that incorporated estimated pup production and is among the smallest reported for a species within the Otariidae. Expand
