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 ...

Comparison of nephrolithiasis prevalence in two bottlenose dolphin (Tursiops truncatus) populations

Frontiers in Endocrinology, 2013
In humans, ammonium urate nephrolithiasis is rare in the Western hemisphere and more common in Japan and developing countries. Among a variety of risk factors, insulin resistance has been associated with urate nephrolithiasis in people.

Identifying Dolphin Whistle Producers With Deep Learning: Moving Beyond Signature Whistles

Marine Mammal Science, Volume 42, Issue 3, July 2026.
ABSTRACT Bottlenose dolphins produce several types of whistle contours, including signature whistles, shared whistles, copies of conspecifics' signature whistles, and variant whistles. While signature whistles as individual identifiers are well studied, less has been demonstrated for identifying dolphins from non‐signature whistle types.

Comparative Immunopathology of Cetacean morbillivirus Infection in Free-Ranging Dolphins From Western Mediterranean, Northeast-Central, and Southwestern Atlantic

Frontiers in Immunology, 2019
Cetacean morbillivirus (CeMV; Paramyxoviridae) causes epizootic and interepizootic fatalities in odontocetes and mysticetes worldwide. Studies suggest there is different species-specific susceptibility to CeMV infection, with striped dolphins (Stenella ...

Chronic interaction between humans and free-ranging bottlenose dolphins near Panama City Beach, Florida

, 2004
‘Swim-with’ activities, in which humans enter the water to interact with free-ranging cetaceans, are a popular form of nature tourism; however, there is considerable disagreement as to whether these encounters constitute a threat to the animals.

Investigating the Predation Risk of Coastal Dolphins via the Presence of Shark Bite Scars Across Southeast Queensland, Australia

Ecology and Evolution, Volume 16, Issue 6, June 2026.
Shark bite scars were analysed on coastal dolphins in southeast Queensland, Australia to compare the predation risk between species and habitats. Australian humpback dolphins (Sousa sahulensis) exhibited the highest bite rates and individuals found in sheltered waters had higher shark bite scar prevalence than open waters.
