The Foe You Know: Observations of Interspecific Interactions Between Small Cetaceans and Northern Resident Killer Whales (Orcinus orca) in the Northeast Pacific [PDF]

Ecology and Evolution
We documented the first aerial observations of interspecific interactions of fish‐eating, northern resident killer whales (Orcinus orca) with two small cetacean species, Dall's porpoises (Phocoenoides dalli) and Pacific white‐sided dolphins ...

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 ...

What’s at Play: Humpback Whale Interaction with Seaweed Is a Global Phenomenon

Journal of Marine Science and Engineering, 2023
The use of objects by cetaceans is well known, and their ability to interact with their environment in complex behaviours has been demonstrated previously.

An HMM-DNN-Based System for the Detection and Classification of Low-Frequency Acoustic Signals from Baleen Whales, Earthquakes, and Air Guns off Chile

Remote Sensing, 2023
Marine passive acoustic monitoring can be used to study biological, geophysical, and anthropogenic phenomena in the ocean. The wide range of characteristics from geophysical, biological, and anthropogenic sounds sources makes the simultaneous automatic ...

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 ...

The role of aquaria in beluga research and conservation

Polar Research, 2021
Aquaria that care for and maintain belugas (Delphinapterus leucas) under professional care have the opportunity to contribute to the conservation of wild belugas through research, expertise in animal care and husbandry, and engaging and educating the ...

Modeling Fine-Scale Cetaceans’ Distributions in Oceanic Islands: Madeira Archipelago as a Case Study

Frontiers in Marine Science, 2021
Species distributional estimates are an essential tool to improve and implement effective conservation and management measures. Nevertheless, obtaining accurate distributional estimates remains a challenge in many cases, especially when looking at the ...

The prelude to industrial whaling: identifying the targets of ancient European whaling using zooarchaeology and collagen mass-peptide fingerprinting

Royal Society Open Science, 2023
Taxonomic identification of whale bones found during archaeological excavations is problematic due to their typically fragmented state. This difficulty limits understanding of both the past spatio-temporal distributions of whale populations and of ...

The essential role of AMPA receptor GluR2 subunit RNA editing in the normal and diseased brain

Frontiers in Molecular Neuroscience, 2012
AMPA receptors are comprised of different combinations of GluR1-GluR4 (also known as GluA1-GluA4 and GluR-A to GluR-D) subunits. The GluR2 subunit is subject to Q/R site RNA editing by the ADAR2 enzyme, which converts a codon for glutamine (Q), present ...
