Reproductive Tactics in Baleen Whales
, 2023 AbstractWhile a variety of reproductive tactics are readily witnessed in odontocetes, such behaviors can be far more elusive in baleen whales and in some cases are yet to be observed. This leads researchers to study the reproductive behaviors in mysticetes using a variety of research methods which have improved greatly in recent years.

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

Oral cavity hydrodynamics and drag production in Balaenid whale suspension feeding. [PDF]
PLoS ONE, 2017 Balaenid whales feed on large aggregates of small and slow-moving prey (predominantly copepods) through a filtration process enabled by baleen. These whales exhibit continuous filtration, namely, with the mouth kept partially opened and the baleen ...

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

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.

Seasonal and Diel Acoustic Occurrence of Sei Whales in Oregon, USA
Marine Mammal Science, Volume 42, Issue 4, October 2026.ABSTRACT The behavior, distribution, and life history of sei whales (Balaenoptera borealis) are largely unknown in the North Pacific. We analyzed data from three bottom‐mounted acoustic recorders deployed 25 (shelf; depth = 300 m), 45 (slope; depth = 630 m), and 65 (abyssal; depth = 2860 m) nautical miles off of Newport, Oregon, USA that recorded ...
