Occurrence and Whistle Characteristics of Small Odontocetes in Two Coastal Regions of the Sea of Japan

Marine Mammal Science, Volume 42, Issue 3, July 2026.
ABSTRACT This study investigated the occurrence and whistle characteristics of small odontocetes in Wakasa Bay and Aso Bay, located in the coastal waters of the Sea of Japan, where ecological data are limited. Passive acoustic monitoring using A‐tag and SoundTrap was conducted from 2022 to 2024, with detections on 8.8% and 12.4% of monitoring days at ...

Challenges of collecting blow from small cetaceans

Ecosphere, 2019
We trialed the collection of blow samples using a waterproof electric multirotor (quadcopter) drone from two free‐ranging dolphin species, the abundant and approachable bottlenose dolphin (Tursiops aduncus) and the less common and boat shy humpback ...

Foraging Ecology and Fisheries Interactions of Common Bottlenose Dolphins (Tursiops truncatus) Inferred From Strandings in Western Iberian Atlantic Waters

Marine Mammal Science, Volume 42, Issue 3, July 2026.
ABSTRACT The common bottlenose dolphin (Tursiops truncatus) is a resident species along the Portuguese mainland coast, yet knowledge of its stranding patterns and feeding ecology is scarce. This study presents a comprehensive assessment of strandings (n = 264, from 1980 to 2019) and feeding ecology based on stomach content analysis (n = 43 from 1997 to

Exploring Progesterone Levels and Scaled Mass Index as Predictors of Pregnancy in Free‐Ranging Belugas

Marine Mammal Science, Volume 42, Issue 3, July 2026.
ABSTRACT Monitoring pregnancy rates can provide vital information regarding a population's viability and trajectory. This study combined drone‐based photogrammetry with biopsy darting to determine if the Scaled Mass Index (SMI) estimated from aerial images can be used to identify pregnant, free‐ranging St.

Machine Learning Detection of Scarring Events in Killer Whales

Marine Mammal Science, Volume 42, Issue 3, July 2026.
ABSTRACT Detection and analysis of body scars using photo‐identification data of cetaceans can provide insights into life history, behavior, and exposure to threats, but such analyses typically require manual examination of large image datasets. To explore whether machine learning can assist this process, we developed a pipeline for automatically ...

Vulnerability to Global Environmental Change? Isotopic Inference of a Resident Population of Common Bottlenose Dolphins, Tursiops truncatus, in a Coastal Lagoon in the Southern Gulf of Mexico

Marine Mammal Science, Volume 42, Issue 3, July 2026.
ABSTRACT Through the isotopic composition of 211 samples of six different tissues (muscle, liver, heart, kidney, spleen, and lung) obtained from 51 Tursiops truncatus strandings over nearly a decade (2013–2022), this study evaluated the impact of environmental variations on a resident population in a coastal lagoon in the southern Gulf of Mexico ...

Identification of Lactobacillus strains with probiotic features from the bottlenose dolphin (Tursiops truncatus)

Journal of Applied Microbiology, 2013
In order to develop complementary health management strategies for marine mammals, we used culture‐based and culture‐independent approaches to identify gastrointestinal lactobacilli of the common bottlenose dolphin, Tursiops truncatus.
