Genomic analyses reveal trans-generational haul out site fidelity in leopard seals [PDF]

Scientific Reports
As top predators, leopard seals (Hydrurga leptonyx) have a key role in Southern Ocean ecosystems. For example, this species has driven the local collapse of Antarctic fur seals (Arctocephalus gazella) at Cape Shirreff, in the northern Antarctic Peninsula.

Isolation of Toxoplasma gondii from the placenta of northern fur seals (Callorhinus ursinus) and potential transplacental transmission of the parasite [PDF]

Parasite
Toxoplasma gondii infects almost all warm-blooded animals, including marine mammals. Toxoplasmosis has been reported in wild and captive marine mammals in North America; however, no viable T. gondii strains have been isolated from northern fur seals.

Pathobiology of Highly Pathogenic Avian Influenza A (H5N1 Clade 2.3.4.4b) Virus from Pinnipeds on Tyuleniy Island in the Sea of Okhotsk, Russia [PDF]

Viruses
Highly pathogenic avian influenza (HPAI) A(H5N1) clade 2.3.4.4b has recently emerged as a major threat to wildlife, agriculture, and public health due to its expanding host range and the increasing frequency of spillover into mammals. In July–August 2023,

Current and future habitat suitability of northern fur seals and overlap with the commercial walleye pollock fishery in the eastern Bering Sea [PDF]

Movement Ecology
Background Understanding the abiotic and biotic drivers of species distribution is critical for climate-informed ecosystem management. We aimed to understand habitat selection of northern fur seals in the eastern Bering Sea, a declining population that ...

Systemic inflammation impairs recovery from hookworm-associated anemia in a wild marine mammal host [PDF]

Frontiers in Immunology
Inflammation is a critical defense against pathogens but can impair iron metabolism and erythropoiesis, potentially causing or exacerbating anemia during infection.

Effects of New Seal Introductions on Conspecific and Visitor Activity

Animals, 2022
Modern zoos and aquariums are defined by several primary goals, which include improving the welfare of their animals, public education, and inspiring visitors to develop an interest in conservation. Animal-Visitor Interactions (AVIs) (i.e., the impact of
