Half a Century of Per‐ and Polyfluoroalkyl Substances in Northern Gannet Eggs: Impact of Regulations

Journal of Applied Toxicology, EarlyView.
ABSTRACT Per‐ and polyfluoroalkyl substances (PFAS), known as “forever chemicals”, are persistent organic pollutants that have been widely used in the industry across the globe for many decades. Their chemical stability, bioaccumulation, and toxicity pose major environmental and health risks. This study examines temporal trends in the concentrations of

Scalable low‐cost seabed landers: the missing link for sustained, integrated, long‐term observations in dynamic shallow seas

Remote Sensing in Ecology and Conservation, EarlyView.
Seabed landers, when equipped with a range of biotic and abiotic sensors, offer a non‐invasive and cost‐effective solution for ecosystem‐scale monitoring of Essential Biodiversity Variables (EBVs) and Essential Ocean Variables (EOVs) in dynamic shallow seas.

First Evidence of Retrospective Findings of Microplastics in Harbour Porpoises (Phocoena phocoena) From German Waters

Frontiers in Marine Science, 2021
Microplastic ingestion by lower trophic level organisms is well known, whereas information on microplastic ingestion, egestion and accumulation by top predators such as cetaceans is still lacking.

Fishing Activity Affected Odontocete Cetacean Distribution in a Marine Protected Area in the East China Sea

Integrative Zoology, EarlyView.
Spatiotemporal distribution of odontocete cetaceans within China's Jiushan Archipelago National Nature Reserve was investigated. Fishing vessels significantly reduced both cetacean acoustic detections and feeding activity, whereas gillnets selectively suppressed cetacean feeding behavior without affecting overall cetacean detection rates.

Observer coverage and interaction rates determine the choice between design‐based and machine learning bycatch estimators for rare species

Conservation Biology, EarlyView.
Abstract Robust estimates of the magnitude of protected species bycatch are essential for effective fisheries management and marine conservation. Existing bycatch estimation methods typically struggle to accurately and precisely estimate the bycatch of rare species as a result of the statistical assumptions necessary to overcome infrequent encounters ...

Reading between the lines: Novel insights on wild Pacific harbour porpoise (Phocoena phocoena vomerina) social communication through narrow-band high frequency click trains.

PLoS ONE
For cetaceans that produce narrow-band high-frequency click trains such as the Pacific harbour porpoise (Phocoena phocoena vomerinae), social acoustic behavior is poorly understood.

A review of methods for defining population structure in the harbour porpoise (Phocoena phocoena)

NAMMCO Scientific Publications, 2003
Wide-ranging methods that have been used to determine population structure, including distribution, life history, biology, ecological factors such as diet and contaminant loads, morphology and genetics, are reviewed.

Homozygosity Accumulated Through Genetic Drift and Inbreeding Underpins High Mutation Load in an Endangered Beluga Whale Population

Molecular Ecology, Volume 35, Issue 16, August 2026.
ABSTRACT Isolated populations are susceptible to decline through the accumulation of deleterious mutations and inbreeding depression. As a consequence of habitat alteration, isolated populations are also expected to become increasingly prevalent.

Echosounders for fish detection disturb harbour porpoises

Environmental Pollution
Abstract The marine world is an acoustic world that has become noisier with the increasing diversity and intensity of human activities at sea. The harbour porpoise ( Phocoena phocoena ) is one of the best-studied cetaceans regarding hearing and responses to human-made underwater ...

Follow-up study after four years shows reduced deterrence effect of pingers on harbour porpoises in Norwegian gillnet fishery

NAMMCO Scientific Publications
We report results from follow-up field trials testing acoustic deterrents (pingers) as a measure to reduce harbour porpoise (Phocoena phocoena) by-catch rates in coastal gillnet fisheries in Norway.
