Multi‐Platform Deployments of Low‐Cost Devices for Cetacean Passive Acoustic Monitoring
Recent advances in affordable, user‐friendly devices offer new opportunities to overcome cost constraints of underwater passive acoustic monitoring (PAM) and expand acoustic data collection. In this study, we deployed low‐cost acoustic recorders and underwater cameras across a range of platforms in the Western Mediterranean, including fishing gear ...

This study established the first fecal hormonal reference values (P4/E2) for the Greater Caribbean manatee. Using non‐invasive ELISA, the authors found no significant differences between mature and immature females, highlighting that long‐term monitoring and ultrasounds are essential to fully understand their complex reproductive cycles.

The Greenland–Scotland Ridge in a Changing Ocean: Time to Act?
ABSTRACT The Greenland–Scotland Ridge is a submarine mountain that rises up to 500 m below the sea surface and extends from the east coast of Greenland to the continental shelf of Iceland and across the Faroe Islands to Scotland. The ridge not only separates deeper ocean basins on either side, that is, the North Atlantic and Arctic oceans, but also ...

Abstract The anatomical description of the hourglass dolphin (Cephalorhynchus cruciger) and the spectacled porpoise (Phocoena dioptrica) remains largely unexplored, due to limited specimen availability and preservation challenges. This study employed digital imaging techniques, conventional histology, and computed tomography to provide visualization of

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 ...

During a survey in June 2025, researchers recorded a presumed Risso's dolphin calf swimming in echelon position within a bottlenose dolphin group off the Catalan coast (north‐eastern Iberian Peninsula). Two possible interpretations are discussed: (1) it may represent the first hybrid calf reported in the Mediterranean, or (2) it may be the first ...

Seven new dolphin mitochondrial genomes and a time-calibrated phylogeny of whales
Background The phylogeny of Cetacea (whales) is not fully resolved with substantial support. The ambiguous and conflicting results of multiple phylogenetic studies may be the result of the use of too little data, phylogenetic methods that do not ...
