Patent Dirofilaria immitis infection in Galapagos sea lion rookeries in San Cristóbal Island [PDF]

Parasitology
The Galapagos sea lion (Zalophus wollebaeki) is an endemic and endangered species that plays a vital role in the ecosystem dynamics of the archipelago. In recent decades, they have faced a significant population decline, related to the effects of climate

The First Population Simulation for the Zalophus japonicus (Otariidae: Sea Lions) on Dokdo, Korea

Journal of Marine Science and Engineering, 2022
The Japanese sea lion (Z. japonicus) has been regarded as an extinct species since the last report on Dokdo in 1951. Not much ecological information on the Z. japonicus on Dokdo (hereafter Dokdo sea lion) is currently available.

Assessment of Australian Sea Lion Bycatch Mortality in a Gillnet Fishery, and Implementation and Evaluation of an Effective Mitigation Strategy

Frontiers in Marine Science, 2022
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.

Assessment of Competition between Fisheries and Steller Sea Lions in Alaska Based on Estimated Prey Biomass, Fisheries Removals and Predator Foraging Behaviour. [PDF]

PLoS ONE, 2015
A leading hypothesis to explain the dramatic decline of Steller sea lions (Eumetopias jubatus) in western Alaska during the latter part of the 20th century is a change in prey availability due to commercial fisheries.

Quantifying the linkages between California sea lion (Zalophus californianus) strandings and particulate domoic acid concentrations at piers across Southern California

Frontiers in Marine Science, 2023
Domoic acid-producing blooms of the diatom genus Pseudo-nitzschia are pervasive in coastal environments globally. Domoic acid, a neurotoxin, accumulates via trophic transfer into marine food webs and is often associated with mass marine mammal mortality ...

Local disconnects in global discourses—The unintended consequences of marine mammal protection on small‐scale fishers

Conservation Letters, 2021
Global commitments prioritize protection of wildlife and improvements to human wellbeing. Local disconnects in these commitments are rarely acknowledged—or their implications assessed—preventing the development of effective solutions.

Galápagos and Californian sea lions are separate species: Genetic analysis of the genus Zalophus and its implications for conservation management

Frontiers in Zoology, 2007
Background Accurate formal taxonomic designations are thought to be of critical importance for the conservation of endangered taxa. The Galápagos sea lion (GSL), being appreciated as a key element of the Galápagos marine ecosystem, has lately been listed

Lipoproteins in pinnipeds: analysis of a high molecular weight form of apolipoprotein E.

Journal of Lipid Research, 1991
We have examined the apolipoprotein content of the lipoproteins of several marine mammals by sodium dodecyl sulfate-polyacrylamide gel electrophoresis. Their apolipoprotein (apo) B-100, apoB-48, and apoA-I migrated to virtually the same position as the ...

A 500 kyr record of global sea-level oscillations in the Gulf of Lion, Mediterranean Sea: new insights into MIS 3 sea-level variability [PDF]

Climate of the Past, 2012
Borehole PRGL1-4 drilled in the upper slope of the Gulf of Lion provides an exceptional record to investigate the impact of late Pleistocene orbitally-driven glacio-eustatic sea-level oscillations on the sedimentary outbuilding of a river fed continental
