First At‐Sea Identifications of Ginkgo‐Toothed Beaked Whale (Mesoplodon ginkgodens): Acoustics, Genetics, and Biological Observations Off Baja California, México

open access: yesMarine Mammal Science, Volume 42, Issue 1, January 2026.
ABSTRACT In 2024, an expedition was conducted off northwestern Baja California, México, to find and identify the beaked whale species that produced the BW43 echolocation pulse previously recorded in this area and elsewhere in the North Pacific. There were five Mesoplodon sightings and 21 BW43 acoustic detections on both a towed array and drifting pole ...

Occurrence, site‐fidelity and photo‐identification of long‐finned pilot whales in Aotearoa New Zealand

open access: yesNew Zealand Journal of Marine and Freshwater Research, Volume 59, Issue 2, Page 398-417, June 2025.
ABSTRACT Despite frequently stranding, little is known about free‐ranging long‐finned pilot whales (Globicephala melas edwardii) in Aotearoa/New Zealand. This study used long‐term data to determine the occurrence, seasonal site‐fidelity, group size distribution and individual identity of pilot whales off the east coast of New Zealand.

First Record of a Collapsed Dorsal Fin in a White-beaked Dolphin Lagenorhynchus albirostris, with a Gunshot Wound as a Possible Cause [PDF]

open access: yes, 2008
Collapsed dorsal fins are rare in odontocete cetaceans, having been reported for only a few species. We present the first known case in a White-beaked Dolphin (Lagenorhynchus albirostris Gray, 1846), photographed off northern Newfoundland, Canada in ...

Understanding causes of morbidity and mortality in Southern Hemisphere small Odontoceti: a scoping review

open access: yesMammal Review, Volume 55, Issue 2, April 2025.
This review identifies key causes of morbidity and mortality in Southern Hemisphere small Odontoceti, highlighting significant anthropogenic threats and the enhanced need for conservation strategies. Key findings include high rates of entanglements and a diverse range of infectious pathogens. Abstract Marine mammals serve as sentinels for environmental

Predicting time‐at‐depth weighted biodiversity patterns for sharks of the North Pacific

open access: yesEcography, Volume 2025, Issue 3, March 2025.
Depth is a fundamental and universal driver of ocean biogeography but it is unclear how the biodiversity patterns of larger, more mobile organisms change as a function of depth. Here, we developed a predictive biogeography model to explore how information of mobile species' depth preferences influence biodiversity patterns.

Vulnerability of Eastern Tropical Pacific chondrichthyan fish to climate change

open access: yesGlobal Change Biology, Volume 30, Issue 7, July 2024.
This assessment identifies sharks' vulnerability to climate change in a data‐poor tropical region and suggests management actions. Abstract Climate change is an environmental emergency threatening species and ecosystems globally. Oceans have absorbed about 90% of anthropogenic heat and 20%–30% of the carbon emissions, resulting in ocean warming ...

Blubber biopsy in common bottlenose dolphins using a novel biopsy puncher: Evaluation of the impact on living individuals and possibility of applications in cetacean research

open access: yesJournal of Experimental Zoology Part A: Ecological and Integrative Physiology, Volume 341, Issue 5, Page 499-508, June 2024.
Abstract Biopsy has recently become a preferred protocol for sampling the skin and blubber of many cetacean species, although it is desirable to collect as minimally invasive as possible. Here, the effect of biopsy sampling on the captive common bottlenose dolphins was evaluated by analyzing the process of wound healing and changes in hematological and
