Allocation and use of body energy reservoirs in striped dolphins and Blainville's beaked whales: Snowball effect in negative energetic balance

open access: yesMarine Mammal Science, Volume 41, Issue 2, April 2025.
Abstract Climate change, overfishing, and other anthropogenic activities can negatively impact the energetic balance and body condition of cetaceans. Still, cetaceans must meet their energetic demands for survival, which are more expensive to maintain in the marine environment.

Acoustic occurrence of deep‐diving cetaceans in the southern Adriatic Sea

open access: yesMarine Mammal Science, Volume 41, Issue 2, April 2025.
Abstract Goose‐beaked whale (Ziphius cavirostris) and sperm whale (Physeter macrocephalus) are two deep‐diving odontocete species known to occur in the southern Adriatic Sea, based on intermittent stranding and sighting data. To get a better understanding of their presence in this region, we studied the occurrence of echolocation clicks produced by ...

Killer whale (Orcinus orca) occurrence in Icelandic waters revealed by passive acoustic monitoring

open access: yesMarine Mammal Science, Volume 41, Issue 2, April 2025.
Abstract The distribution and occurrence of killer whales around Iceland are primarily studied in coastal herring grounds, with limited knowledge beyond these areas. This study employed opportunistic passive acoustic monitoring (PAM) data from four regions across Icelandic inshore and offshore waters to investigate killer whale distribution between ...

First Photo-Identification Study of the Sperm Whale (Physeter macrocephalus) in the Aeolian Archipelago and the Northern Coast of Sicily (Southern Tyrrhenian Sea, Italy)

open access: yesDiversity
(1) While photo-identification has been used to study sperm whales worldwide, no long-term photo-id studies are available from the Southern Tyrrhenian Sea for the Mediterranean endangered population.
