Humpback whales feed on hatchery-released juvenile salmon [PDF]

open access: yesRoyal Society Open Science, 2017
Humpback whales are remarkable for the behavioural plasticity of their feeding tactics and the diversity of their diets. Within the last decade at hatchery release sites in Southeast Alaska, humpback whales have begun exploiting juvenile salmon, a ...

Comparative review of entanglement risk assessments for cetacean conservation and management

open access: yesConservation Biology, EarlyView.
Abstract Cetacean entanglement in fishing gear remains a major global threat that exposes persistent gaps in how fisheries management frameworks manage risk to nontarget species. Ecological risk assessment (ERA) offers a structured way to link exposure and consequences to an explicit statement of risk, but entanglement risk assessments vary widely in ...

Incorporation of Humpback whale song in an electroacoustic concert piece [PDF]

open access: yes, 2013
Inclusion and usage of humpback whale song within the context of an electroacoustic or acoustic ensemble has been used in recent twentieth and twenty-first century literature such as George Crumb's Vox Balaenae.

Comparing the underwater soundscape of the Hawaiian Islands Humpback Whale National Marine Sanctuary and potential influences of the COVID-19 pandemic

open access: yesFrontiers in Marine Science
Passive acoustic monitoring is an effective technique for long-term monitoring of the soundscape in marine protected areas. Ocean noise is a key concern for the U.S.

Multi-year presence of humpback whales in the Atlantic sector of the Southern Ocean but not during El Niño

open access: yesCommunications Biology, 2021
Schall et al. use passive acoustic recordings of humpback whale calls to report the presence of humpback whales in the Atlantic sector of the Southern Ocean between 2011 and 2018. This serves as the first long-term report of humpback whales on a Southern

The Greenland–Scotland Ridge in a Changing Ocean: Time to Act?

open access: yesMarine Ecology, EarlyView.
ABSTRACT The Greenland–Scotland Ridge is a submarine mountain that rises up to 500 m below the sea surface and extends from the east coast of Greenland to the continental shelf of Iceland and across the Faroe Islands to Scotland. The ridge not only separates deeper ocean basins on either side, that is, the North Atlantic and Arctic oceans, but also ...

Stable Isotope Composition of Skin Layers Confirms Trophic Differentiation of Baird's and Sato's Beaked Whales (Berardius spp.) in the Western North Pacific

open access: yesRapid Communications in Mass Spectrometry, Volume 40, Issue 17, 15 September 2026.
ABSTRACT Rationale Closely related whale species can appear similar yet occupy distinct ecological niches. Sato's beaked whale (Berardius minimus) was only recently recognized as a separate species and was previously grouped with Baird's beaked whale (Berardius bairdii), limiting our understanding of their ecological differences.

Applicability of Information Theory to the Quantification of Responses to Anthropogenic Noise by Southeast Alaskan Humpback Whales

open access: yesEntropy, 2008
We assess the effectiveness of applying information theory to the characterization and quantification of the affects of anthropogenic vessel noise on humpback whale (Megaptera novaeangliae) vocal behavior in and around Glacier Bay, Alaska.

Ecological implications and lessons from high pathogenicity avian influenza H5N1 2.3.4.4b in Antarctica

open access: yesEcological Solutions and Evidence, Volume 7, Issue 3, July–September 2026.
HPAI H5N1 was confirmed in 22 South Polar Skuas and one Kelp Gull on Dismal and Horseshoe Islands, Marguerite Bay, Western Antarctic Peninsula in early 2025, with high mortalities consistent with global trends. Rapid antigen tests showed 90% agreement with rRT‐PCR, supporting their utility for early detection in remote environments.

A contribution to the anatomy of two rare cetacean species: The hourglass dolphin (Cephalorhynchus cruciger) and the spectacled porpoise (Phocoena dioptrica)

open access: yesThe Anatomical Record, Volume 309, Issue 7, Page 1797-1820, July 2026.
Abstract The anatomical description of the hourglass dolphin (Cephalorhynchus cruciger) and the spectacled porpoise (Phocoena dioptrica) remains largely unexplored, due to limited specimen availability and preservation challenges. This study employed digital imaging techniques, conventional histology, and computed tomography to provide visualization of
