A negative trend in abundance and an exceeded mortality limit call for conservation action for the Vulnerable Belt Sea harbour porpoise population

open access: yesFrontiers in Marine Science
The management and conservation of biodiversity relies on information on both the abundance of species and the potential impact of threats. Globally, one of the largest threats towards marine biodiversity is bycatch in fisheries.

Harbor Porpoise (Phocoena phocoena) Reaction to a 3D Seismic Airgun Survey in the North Sea

open access: yesFrontiers in Marine Science, 2020
The most common cetacean in the North Sea is the harbor porpoise (Phocoena phocoena). Underwater noise is increasingly recognized as a source of impact on the marine environment and seismic airguns were one of the first man-made high intensity sound ...

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

open access: yesEvolutionary 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 ...

The Importance of Individual Body Condition in Mammalian Behavioural Responses to Disturbance

open access: yesMammal Review, Volume 56, Issue 2, June 2026.
Body condition, shaped by the balance between energy demands and reserves, predictably shapes mammalian disturbance responses. Poor‐condition individuals adopt needs‐based strategies, accepting greater risks to meet immediate energetic needs, while good‐condition individuals follow asset‐protection strategies, minimizing risks to protect their survival

Whole‐Genome‐Sequencing Reveals Demographic History and Patterns of Parallel Adaptive Evolution in Indo‐Pacific Bottlenose Dolphins (Tursiops aduncus) Across Coastal Australian Seascapes

open access: yesMolecular Ecology, Volume 35, Issue 11, June 2026.
ABSTRACT Understanding how demographic dynamics interact with environmental heterogeneity is central to explaining patterns of genomic variation in the marine realm. Indo‐Pacific bottlenose dolphins (Tursiops aduncus) occur along most of the Australian coastline, from tropical to temperate waters, encompassing pronounced differences in temperature ...

Bartonella henselae in Porpoise Blood

open access: yesEmerging Infectious Diseases, 2005
We report detection of Bartonella henselae DNA in blood samples from 2 harbor porpoises (Phocoena phocoena). By using real-time polymerase chain reaction, we directly amplified Bartonella species DNA from blood of a harbor porpoise stranded along the ...

Clicking for supper

open access: yeseLife, 2015
When close to prey, porpoises actively widen their sonar beam, which may make it harder for the prey to escape.
