Diving on damage—the muscle transcriptome of parasitic infested harbor porpoises (Phocoena phocoena) hints at oxidative stress but not hypoxia

Frontiers in Marine Science, 2023
The only native cetacean in German waters, the harbor porpoise (Phocoena phocoena), is impacted by numerous pathological lesions in the respiratory tract mainly caused by parasites or bacteria.

Spatio-Temporal Variability of Harbor Porpoise Life History Parameters in the North-East Atlantic

Frontiers in Marine Science, 2020
Harbor porpoises exhibit early maturation, relatively short gestation/lactation periods and a faster rate of reproduction as compared to other cetacean species.

Histochemical and Immunohistochemical Characterizations of Hepatic Trematodiasis in Odontocetes

Frontiers in Veterinary Science, 2020
Hepatic trematodiasis is a common condition in a number of free-ranging cetacean species, which occasionally result in severe hepatic and/or pancreatic lesions.

Counting cases, conserving species: addressing highly pathogenic avian influenza in wildlife

Biological Reviews, EarlyView.
ABSTRACT Highly pathogenic avian influenza (HPAI) has become a critical threat to wildlife, shifting from a seasonal epizootic to a persistent, year‐round panzootic with global consequences. Here, we summarise the origin, evolutionary mechanisms, and expanding host range of the current H5N1 virus (clade 2.3.4.4b) and assess its impact on wildlife. Over

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

Resident Harbor Porpoises (Phocoena phocoena vomerina) in the Salish Sea: Photo-Identification Shows Long-Term Site Fidelity, Natal Philopatry, and Provides Insights into Longevity and Behavior

Oceans
Harbor porpoises have been well studied in locations worldwide, but relatively little research has focused on site fidelity of individuals, which influences population structure and determines appropriate management and conservation measures.

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.

Yulendji Bunwurrung Walagunh With Western Science: Ecological Insights, Emerging Research Questions and Future Directions From Bunurong Stories of Marine Mammals

Ecology and Evolution, Volume 16, Issue 8, August 2026.
Indigenous Knowledge systems contain deep, place‐based ecological insights developed over generations but remain underrepresented in biodiversity assessments and conservation planning. This study explores yulendji Bunwurrung (Bunurong knowledge) through five Stories shared by a Bunurong Elder, using thematic analysis and comparison with contemporary ...

Predicting Harbor Porpoise Strandings Based on Near-Shore Sightings Indicates Elevated Temporal Mortality Rates

Frontiers in Marine Science, 2021
The increase in anthropogenic activities and their potential impact on wildlife requires the establishment of monitoring programs and identification of indicator species. Within marine habitats, marine mammals are often used as ecosystem sentinels, which

Mapping Seasonal Interaction Risk Between Harbour Porpoises and Gillnet Fisheries to Inform Management Thresholds

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 7, July 2026.
ABSTRACT When empirical bycatch data are limited, risk‐based assessments offer a valuable tool for identifying areas where marine mammals and fisheries are most likely to interact. The harbour porpoise (Phocoena phocoena) is among the most vulnerable to incidental capture in gillnet fisheries.
