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.

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 ...

Lévy Flight Trajectory-Based Whale Optimization Algorithm for Global Optimization
IEEE Access, 2017 The whale optimization algorithm (WOA) has been shown to be powerful in searching for an optimal solution. This paper proposes an improvement to the whale optimization algorithm that is based on a Lévy flight trajectory and called the Lévy flight ...

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.

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

The International Whaling Commission—Beyond Whaling [PDF]
Frontiers in Marine Science, 2016 Since its establishment in 1946 as the international body intended to manage whaling, the International Whaling Commission (IWC) has expanded its areas of interest to ensure the wider conservation of whales. Several key conservation topics have been taken forward under its auspices including climate change, chemical and noise pollution, marine debris ...

Animals, 2022 Gray whales (Eschrichtius robustus) show high site fidelity to feeding and breeding areas. The whales’ annual cycle could be learned or be driven by factors such as prey abundance or ocean conditions. Long-term line transect and photo-identification data
