Using energetic models to investigate the survival and reproduction of beaked whales (family Ziphiidae) [PDF]

, 2012
Mass stranding of several species of beaked whales (family Ziphiidae) associated with exposure to anthropogenic sounds has raised concern for the conservation of these species.

Drone-based photogrammetry reveals differences in humpback whale body condition and mass across North Atlantic foraging grounds

Frontiers in Marine Science
Baleen whales are key consumers in marine ecosystems and can serve as ecosystem sentinels. Body condition, defined as an individual’s energy stores relative to its structural size, can provide a useful proxy for health in baleen whales.

Underwater Ambient Noise in a Baleen Whale Migratory Habitat Off the Azores

Frontiers in Marine Science, 2017
Assessment of underwater noise is of particular interest given the increase in noise-generating human activities and the potential negative effects on marine mammals which depend on sound for many vital processes.

Humpback Highs and Lows Amid Shifting Seas and a Northeast Pacific Marine Heatwave: Whale Demographics in the Main Hawaiian Islands, 2002–2023

Marine Mammal Science, Volume 42, Issue 4, October 2026.
ABSTRACT North Pacific humpback whales are a celebrated conservation success, rebounding from extensive commercial whaling. Yet they remain vulnerable to the impacts of climate change, a multifaceted stressor that can exacerbate existing threats. During 2013–2016, a Northeast Pacific marine heatwave severely reduced forage availability in their feeding

Stable isotopes infer the diet and habitat of the enigmatic pygmy right whale (Caperea marginata) off southern Australia

Frontiers in Marine Science, 2023
In the Southern Hemisphere, baleen whales generally undertake migrations between productive feeding grounds at high latitudes and breeding grounds at lower latitudes. Pygmy right whales (Caperea marginata) (PRW) are the smallest and most enigmatic baleen

Status of the world's baleen whales

Marine Mammal Science, 2015
AbstractNo global synthesis of the status of baleen whales has been published since the 2008IUCNRed List assessments. Many populations remain at low numbers from historical commercial whaling, which had ceased for all but a few by 1989. Fishing gear entanglement and ship strikes are the most severe current threats.

Group‐Specific Variation in Heterodyne Frequencies of Biphonic Calls in Resident (R‐Type) Killer Whales Orcinus orca ater

Marine Mammal Science, Volume 42, Issue 4, October 2026.
ABSTRACT Biphonation—the simultaneous production of two independent fundamental frequencies within a single vocalization—is a prominent feature of killer whale calls, yet the factors influencing the presence and intensity of heterodyne frequencies, which arise from interactions between these fundamentals, remain poorly understood. We analyzed long‐term
