Globally, the bycatch of marine mammals in fisheries represents the greatest source of human-caused mortality that threatens the sustainability of many populations and species. The Australian sea lion (Neophoca cinerea) is an endangered species, whos

The endangered Australian sea lion extensively overlaps with and regularly becomes by-catch in demersal shark gill-nets in South Australian shelf waters

Publikováno v: Biological Conservation. 157:386-400

Australian sea lions ( Neophoca cinerea ) have typically small breeding colonies, many of which are genetically distinct populations due to female philopatry (i.e. breeding site fidelity). This situation may increase the vulnerability of the species

Odontocete bycatch and depredation in longline fisheries: A review of available literature and of potential solutions

Autor: Simon Childerhouse, Derek J. Hamer, Nick Gales

Publikováno v: Marine Mammal Science. 28:E345-E374

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 viability of longline fisheries. This review attempts to defin

Assessing the effectiveness of the Great Australian Bight Marine Park in protecting the endangered Australian sea lion Neophoca cinerea from bycatch mortality in shark gillnets

Autor: T. M. Ward, P. D. Shaughnessy, Derek J. Hamer, S. R. Clark

Publikováno v: Endangered Species Research. 14:203-216

The Endangered Australian sea lion Neophoca cinerea occurs in low numbers, exhibits low fecundity, extreme philopatry and substantial population genetic structure at the breeding colony level. These traits may increase susceptibility to population de

Telomere length and age in pinnipeds: The endangered Australian sea lion as a case study

Autor: Christopher Izzo, Stephen C. Donnellan, Bronwyn M. Gillanders, Terry Bertozzi, Derek J. Hamer

Publikováno v: Marine Mammal Science. 27:841-851

Telomeres are the protective caps at the ends of all eukaryotic chromosomes. Because DNA replication of chromosome ends is incomplete, telomeres undergo sequence loss with each cell division resulting in the progressive shortening of their lengths. T

Measurement, management and mitigation of operational interactions between the South Australian Sardine Fishery and short-beaked common dolphins (Delphinus delphis)

Autor: Richard McGarvey, Derek J. Hamer, Tim M. Ward

Publikováno v: Biological Conservation. 141:2865-2878

This study arose from recommendations given in response to a legislated ecological assessment of the South Australian Sardine Fishery in 2004, urging it to: (i) attempt to mitigate operational interactions with marine mammals if excessive levels were

Seal–fishery operational interactions: Identifying the environmental and operational aspects of a trawl fishery that contribute to by-catch and mortality of Australian fur seals (Arctocephalus pusillus doriferus)

Autor: Simon D. Goldsworthy, Derek J. Hamer

Publikováno v: Biological Conservation. 130:517-529

Australian fur seals are known to interact directly (i.e. operational interactions) with trawlers fishing in the winter blue grenadier trawl fishery of western Tasmania, Australia. The purpose of this study was to identify the environmental and opera

Assessing the use of milk fatty acids to infer the diet of the Australian sea lion (Neophoca cinerea)

Autor: Alastair M. M. Baylis, Peter D. Nichols, Derek J. Hamer

Publikováno v: Wildlife Research. 36:169

Information on the diet of threatened species is important in devising appropriate management plans to ensure their conservation. The Australian sea lion (Neophoca cinerea) is Australia’s only endemic and globally one of the least numerous pinniped
