Killer whale presence drives bowhead whale selection for sea ice in Arctic seascapes of fear

Proceedings of the National Academy of Sciences of the United States of America, 2020
Significance Behavioral responses of prey to perceived predation risk are now recognized as important components of predator−prey interactions, but have rarely been quantified in marine vertebrates.

Comparative organization of the claustrum: what does structure tell us about function?

Frontiers in Systems Neuroscience, 2014
The claustrum is a subcortical nucleus present in all placental mammals. Many anatomical studies have shown that its inputs are predominantly from the cerebral cortex and its outputs are back to the cortex.

Satellite tracking reveals novel migratory patterns and the importance of seamounts for endangered South Pacific humpback whales [PDF]

Royal Society Open Science, 2015
The humpback whale population of New Caledonia appears to display a novel migratory pattern characterized by multiple directions, long migratory paths and frequent pauses over seamounts and other shallow geographical features.

A record of fossil shallow-water whale falls from Italy [PDF]

, 2014
Twenty-five Neogene-Quaternary whales hosted in Italian museum collections and their associated fauna were analysed for evidence of whale-fall community development in shallow-water settings.

Predicting global killer whale population collapse from PCB pollution

Science, 2018
PCB—still a problem Until they were recognized as highly toxic and carcinogenic, polychlorinated biphenyls (PCBs) were once used widely. Their production was banned in the United States in 1978, though they are still produced globally and persist in the ...

Memory and resource tracking drive blue whale migrations

Proceedings of the National Academy of Sciences of the United States of America, 2019
Significance The causes and consequences of animal migration have received substantial research attention, yet the mechanisms underlying this global phenomenon remain largely untested in marine systems. By combining 10 years of satellite tracking data on

Ecological succession of a Jurassic shallow-water ichthyosaur fall. [PDF]

, 2014
After the discovery of whale fall communities in modern oceans, it has been hypothesized that during the Mesozoic the carcasses of marine reptiles created similar habitats supporting long-lived and specialized animal communities.

Survival Rates and Capture Heterogeneity of Bottlenose Dolphins (Tursiops truncatus) in the Shannon Estuary, Ireland

Frontiers in Marine Science, 2021
Adult survival is arguably the most important demographic parameter for long-lived species as it has a large impact on population growth, and it can be estimated for cetacean populations using natural markings and mark-recapture (MR) modelling.
