Occurrence and Whistle Characteristics of Small Odontocetes in Two Coastal Regions of the Sea of Japan

Marine Mammal Science, Volume 42, Issue 3, July 2026.
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 ...

Feeding ecology of harbour porpoises Phocoena phocoena stranded on the Galician coast (NW Spain) between 1990 and 2018

Endangered Species Research
Diet studies on the endangered and genetically distinct Iberian population of the southern harbour porpoise Phocoena phocoena are scarce. The present study provides updated information on the feeding ecology of this cetacean along the Galician coast (NW ...

Summer Abundance of Harbour Porpoises (Phocoena phocoena) in the Coastal Waters of Iceland and the Faroe Islands

NAMMCO Scientific Publications, 2020
This study presents the first fully corrected abundance estimates for the harbour porpoise (Phocoena phocoena) for Iceland and the Faroe Islands. In both regions reliable estimates are needed to assess the impact of by-catch and other threats to harbour ...

The Inside Waters of Vancouver Island Are Critical Foraging Habitat for West Coast Transient Killer Whales

Marine Mammal Science, Volume 42, Issue 3, July 2026.
ABSTRACT West Coast Transient (WCT) killer whales (Orcinus orca rectipinnus) hunt marine mammals along the west coast of North America from California to southeastern Alaska. However, little information is available on their seasonal use of nearshore areas and the relative importance of different parts of their range.

Intraspecific variation of cochlear morphology in bowhead and beluga whales

The Anatomical Record, Volume 309, Issue 6, Page 1514-1529, June 2026.
Abstract The bony labyrinth of the petrosal bone, a distinctive feature of mammal skulls, is often identified in micro‐computed tomography imaging to infer species' physiological and ecological traits. When done as part of a comparative study, one individual specimen is normally considered representative of a species, and intraspecific variation is ...

Climate change causing starvation in harbour porpoises? [PDF]

Biology Letters, 2007
Recently, [MacLeod et al . (2007)][1] analysed data from harbour porpoises ( Phocoena phocoena ) stranded on Scottish North Sea coasts in March–May of 1993–2003. Comparing 2002–2003 data against baseline data from previous years, they suggest that reductions in sandeel prey have increased ...

Temporal changes in the dietary niche of sympatric seals provides insight into the role of competition in population declines

Oikos, Volume 2026, Issue 6, June 2026.
Competition theory suggests that interspecific prey competition can result in changes to the dietary niche, but obtaining timeseries of data from sympatric species experiencing temporal variation in competition is challenging. Scotland is an important area for two species of seals, but over the past 20 years, populations of harbour seals Phoca vitulina

Whole Genome Analyses of the Endangered Northern Abalone (Haliotis kamtschatkana) Reveal Population Differentiation and a Genomic Signature of a Dramatic Population Decline

Evolutionary Applications, Volume 19, Issue 6, June 2026.
ABSTRACT Despite widespread declines of many wildlife species, the effects of population decline on the genome and the recovery potential of affected species are still poorly understood, especially beyond a few charismatic species. The Northern abalone (or Pinto abalone; Haliotis kamtschatkana) is a marine gastropod mollusk of social, cultural and ...

Harbour porpoises (Phocoena phocoena) in the North Atlantic: Biological parameters

NAMMCO Scientific Publications, 2003
Biological parameters for harbour porpoises are reviewed throughout their range in the North Atlantic. Most information is based on studies of a combination of directed catches, bycatches and strandings.
