Developing Immune Profiles of Endangered Australian Sea Lion (Neophoca cinerea) Pups Within the Context of Endemic Hookworm (Uncinaria sanguinis) Infection [PDF]

Frontiers in Veterinary Science, 2022
As a top predator, the endangered Australian sea lion (Neophoca cinerea) is a sentinel of ecosystem change, where population trends can reflect broader shifts in the marine environment.

Mitigating disease risk in an endangered pinniped: early hookworm elimination optimizes the growth and health of Australian sea lion pups [PDF]

Frontiers in Veterinary Science, 2023
The Australian sea lion (Neophoca cinerea) experiences high pup mortality of seasonally alternating severity, partly attributed to endemic hookworm (Uncinaria sanguinis) infection.

Gut microbiota of endangered Australian sea lion pups is unchanged by topical ivermectin treatment for endemic hookworm infection [PDF]

Frontiers in Microbiology, 2022
The gut microbiota is essential for the development and maintenance of the hosts’ immune system. Disturbances to the gut microbiota in early life stages can result in long-lasting impacts on host health.

Topical ivermectin is a highly effective seal ‘spot-on’: A randomised trial of hookworm and lice treatment in the endangered Australian sea lion (Neophoca cinerea) [PDF]

International Journal for Parasitology: Parasites and Wildlife, 2021
The Australian sea lion (Neophoca cinerea) is an endangered and declining otariid species, with a high rate of pup mortality associated with endemic hookworm (Uncinaria sanguinis) infection a suspected contributor to this decline.

Cytokine RT-qPCR and ddPCR for immunological investigations of the endangered Australian sea lion (Neophoca cinerea) and other mammals [PDF]

PeerJ, 2020
Measurement of cytokine gene expression by reverse transcription quantitative polymerase chain reaction (RT-qPCR) is used widely to assess the immune system of animals and to identify biomarkers of disease, but its application is limited in wildlife ...

In-Air Behavioral Audiograms of Two Australian Sea Lions (Neophoca cinerea) [PDF]

Animals
The Australian sea lion (Neophoca cinerea) is an endangered species with threats including bycatch, prey depletion, pollution, and habitat loss. Coastal and offshore industrial development causes disturbance—largely mediated by noise.

High nutrient transport and cycling potential revealed in the microbial metagenome of Australian sea lion (Neophoca cinerea) faeces. [PDF]

PLoS ONE, 2012
Metagenomic analysis was used to examine the taxonomic diversity and metabolic potential of an Australian sea lion (Neophoca cinerea) gut microbiome. Bacteria comprised 98% of classifiable sequences and of these matches to Firmicutes (80%) were dominant,

Population Structure and Genetic Diversity Analyses Reveal Isolation That May Imperil the Northernmost Colony of the Endangered Australian Sea Lion [PDF]

Ecology and Evolution
Marine environments are experiencing rapid warming, substantially altering ecosystems. Populations at the edge of a species' range are more vulnerable to environmental change as they are first affected and may have limited dispersal opportunities.

Rapid onset of maternal vocal recognition in a colonially breeding mammal, the Australian sea lion. [PDF]

PLoS ONE, 2010
BACKGROUND: In many gregarious mammals, mothers and offspring have developed the abilities to recognise each other using acoustic signals. Such capacity may develop at different rates after birth/parturition, varying between species and between the ...

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.
