Geographical and Seasonal Distribution of Australian Pygmy Right Whales (Caperea marginata) Based on Passive Acoustics

Marine Mammal Science, Volume 42, Issue 2, April 2026.
ABSTRACT The pygmy right whale (Caperea marginata) is one of the least studied mysticete species. To shed light on its geographic and seasonal distribution, we compiled archival acoustic recordings from 26 sites across southern Australia and developed a deep‐learning detector for pygmy right whale “doublet” vocalizations.

Long‐Term Demographic Trends of Near Threatened Coastal Dolphins Living in an Urban Estuary

Ecology and Evolution
Understanding population demography of threatened species and how they vary in relation to natural and anthropogenic stressors is essential for effective conservation. We used a long‐term photographic capture‐recapture dataset (1993–2020) of Indo‐Pacific

Cetacean diversity on the Parnaiba Delta, Maranhão state, northeastern Brazil

Brazilian Journal of Biology
The increase in the research of cetacean surveys on the Brazilian coast has brought new data on the distribution of species never reported before. The present work reviews the current knowledge on cetaceans species and extends this knowledge with an ...

Why do dolphins form mixed-species associations in the Azores ?

, 2008
Mixed-species associations are temporary associations between individuals of different species that are often observed in birds, primates and cetaceans.

Using ANIMAL‐SPOT Deep Learning Framework to Identify Call Types in Killer Whales

Marine Mammal Science, Volume 42, Issue 2, April 2026.
ABSTRACT Killer whales use complex vocalizations to maintain social structure and coordinate behavior, yet automated classification of call types remains challenging due to overlapping calls and structural similarity among call types. I evaluated the performance of the deep learning framework ANIMAL‐SPOT for identifying killer whale call types from raw

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

Marine 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)

The marine mammals of the Dutch Caribbean: a comparison between EEZ sectors, contrasts and concerns [PDF]

We here provide a synoptic overview and preliminary update of the marine mammals of the Dutch Caribbean EEZ based on 279 cetacean sighting and stranding records. The Dutch Caribbean EEZ is composed of two distinct sectors.

Sharing Is Caring?—Pathogens and Pathogen‐Specific Antibodies in Arctic Endemic Seal Species and the Newly Sympatric Harbor Seals in Kongsfjorden, Svalbard

Marine Mammal Science, Volume 42, Issue 2, April 2026.
ABSTRACT Climate change associated transformations of Arctic marine ecosystems are having detrimental impacts on Arctic endemic marine mammals. However, warming conditions are providing new habitats for temperate marine mammals, some of which are expanding into Arctic regions, posing a threat of novel pathogen introduction and disease transmission.
