Increasing Efficiency of Detection and Validation of Baleen Whale Call Presence on Large Acoustic Datasets: A Case Study Using Sei Whale Downsweeps Recorded in Atlantic Canada

open access: yesMarine Mammal Science, Volume 42, Issue 2, April 2026.
ABSTRACT As passive acoustic monitoring (PAM) datasets expand, studies increasingly use automated detectors to analyze baleen whale presence. However, detector errors like false positives (impacting precision, P; proportion of detected calls that are correct), and false negatives (impacting recall, R; proportion of available calls successfully detected)

Correcting Lipid Extraction Effects on Nitrogen Isotopic Values (δ15N) in Cetacean Skin

open access: yesMarine Mammal Science, Volume 42, Issue 2, April 2026.
ABSTRACT Stable isotopes of carbon (δ13C) and nitrogen (δ15N) are widely used to study the feeding ecology of cetaceans, as they provide critical insights into diet and migratory behaviors. Lipids in tissues may bias the interpretation of δ13C. Because of this, lipids need to be extracted before measuring stable isotope ratios, but their removal may ...

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.

Applying the Ecological Trap Concept to Cetaceans

open access: yesMarine Mammal Science, Volume 42, Issue 2, April 2026.
ABSTRACT Wild animals may select poor‐quality habitats due to mismatches between perceived and actual habitat quality, creating ecological traps. Although well explored in terrestrial systems, this concept remains underutilized for marine species.

Population Demographics of Killer Whales (Orcinus orca) in Western Australia

open access: yesMarine Mammal Science, Volume 42, Issue 2, April 2026.
ABSTRACT Understanding population demographics is crucial for the effective conservation of species. This is particularly important for apex predators, such as the killer whale (Orcinus orca), which play important roles in maintaining the structure and function of ecosystems. In this study, we used capture‐mark‐recapture (CMR) modeling to assess killer

Timing is everything: Drivers of interannual variability in blue whale migration. [PDF]

open access: yes, 2020
Blue whales need to time their migration from their breeding grounds to their feeding grounds to avoid missing peak prey abundances, but the cues they use for this are unknown.

A Multi‐Taxa Approach to Estuarine Biomonitoring: Assessing Vertebrate Biodiversity and Ecological Continuity Using Environmental DNA Metabarcoding in the Rance River (Brittany, France)

open access: yesEcology and Evolution, Volume 16, Issue 3, March 2026.
We applied eDNA metabarcoding to assess vertebrate diversity in the Rance Estuary, France, across five stations spanning marine to freshwater environments, including areas upstream and downstream of a tidal power plant dam. A total of 124 vertebrate MOTUs were detected, with community composition reflecting the estuarine gradient and species turnover ...

A Note on Suckling Behavior and Laterality in Nursing Humpback Whale Calves from Underwater Observations

open access: yesAnimals, 2017
We investigated nursing behavior on the Hawaiian breeding grounds for first year humpback whale (Megaptera novaeangliae) calves. We observed and video-documented underwater events with nursing behavior from five different whale groups.
