Killer Whales in the Central Tropical Pacific: Occurrence, Resightings, Morphology, and Acoustics
ABSTRACT Compared to their well‐studied coastal temperate counterparts, killer whales (Orcinus orca) in tropical‐subtropical and oceanic areas are under‐documented. We used sighting, photo‐identification, and acoustic data of killer whales in the central tropical Pacific (CTP), collected from multiple platforms between 2002 and 2023, to assess their ...

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 ...

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

Demographics of the Disappearing Bottlenose Dolphin in Argentina: A Common Species on Its Way Out?
Populations of the once common bottlenose dolphin (Tursiops truncatus) in Argentina have precipitously declined throughout the country in the past decades. Unfortunately, local declines of common species are easily overlooked when establishing priorities for conservation.

Stacks analysis of common bottlenose dolphin RAD sequences
Results of Stacks analysis of RAD sequencing data generated from pooled genomic DNA from common bottlenose dolphins sampled along the Florida Gulf of Mexico coastline. Sample pools include live coastal dolphins from the Florida Panhandle (PLC, N=17) and

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
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 ...

Serological Evidence of Cetacean Morbillivirus Infection in Common Bottlenose Dolphins in Japan
ABSTRACT This study revealed that 41.9% of wild‐born Japanese captive dolphins (18 out of 43 dolphins) have neutralizing antibodies specific to cetacean morbillivirus (CeMV). This finding indicates a widespread yet undetected CeMV infection among wild dolphins in the waters around Japan, occurring without notable epidemic or mass ...
