Porpoises after dark: Seasonal and diel patterns in Pacific harbour porpoise (Phocoena phocoena vomerina) aggregations at one of North America’s fastest growing ports

Frontiers in Marine Science, 2022
Pacific Harbour Porpoise (Phocoena phocoena vomerina) occupy a large range throughout coastal waters of British Columbia. Despite their wide distribution, they remain largely data-deficient regarding abundance and population trends, and as such are ...

Distribution of Cetaceans in the Canary Islands (Northeast Atlantic Ocean): Implications for the Natura 2000 Network and Future Conservation Measures

Frontiers in Marine Science, 2021
The waters of the Canary Islands are considered a hotspot for marine biodiversity, especially regarding cetacean species. Based on this fact, this study pays attention to the spatial distribution pattern of cetacean species and the conservation role of ...

Applying flukeprint environmental DNA to detect skin-associated bacteria from free-ranging West Coast Transient killer whales Orcinus orca rectipinnus [PDF]

Metabarcoding and Metagenomics
Globally, vessel strikes, entanglements, and ocean pollution negatively impact cetaceans by compromising skin integrity and health through direct injury or disease and by increasing susceptibility to chronic bacterial, viral, or fungal infections ...
