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)

Balina Şarkısı: Kambur Balina Megaptera Novaeangliae Kültürlerinde Müzikal Pratikler

open access: yesRast Müzikoloji Dergisi, 2021
Erkek kambur balinalar (Megaptera novaeangliae) “şarkı” olarak adlandırılan uzun, karmaşık ve örüntüleşmiş seslendirme pratikleri sergilerler. Şarkıların işlevi henüz tam olarak anlaşılamamış olsa da hem bir kur davranışı hem de diğer erkek bireylere çeşitli mesajlar veren bir iletişim biçimi olma ihtimali yüksektir.

Unveiling Patterns in Cetacean Strandings Along Southern Atlantic Iberia: Temporal and Spatial Trends, Seasonality, and Causes of Death

open access: yesMarine Mammal Science, Volume 42, Issue 2, April 2026.
ABSTRACT We compiled 46 years of cetacean strandings in the Algarve, Portugal, describing temporal–spatial patterns, size–sex structure, and causes of death (COD). We analyzed national records and years with a dedicated regional stranding network (SN) to assess annual/seasonal trends, spatial hotspots, and compare biometrics and COD.

Repellence Effect of the New Sound for Underwater Speaker of Hydrofoil [PDF]

open access: yesTransNav, 2015
In order to prevent hydrofoil colliding with cetaceans, the underwater speaker (UWS) has been installed to repel cetaceans. Yamada et al. (2012) analyzed and devised the UWS sound as it fits the cetaceans' acoustic properties to prevent the collision ...

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 ...

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

Photo-identification confirms that humpback whales (Megaptera novaeangliae) from eastern Australia migrate past New Zealand but indicates low levels of interchange with breeding grounds of Oceania [PDF]

open access: yes, 2014
Recent photo-identification and genetic studies have identified at least five discrete breeding populations in Australia and Oceania: western Australia (D), eastern Australia (E (i)), New Caledonia (E (ii)), Tonga (E (iii)), French Polynesia and the Cook
