Asymmetric and Spiraled Genitalia Coevolve with Unique Lateralized Mating Behavior

Scientific Reports, 2020
Asymmetric genitalia and lateralized mating behaviors occur in several taxa, yet whether asymmetric morphology in one sex correlates or coevolves with lateralized mating behavior in the other sex remains largely unexplored.

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

Seal Bomb Noise as a Potential Threat to Monterey Bay Harbor Porpoise

Frontiers in Marine Science, 2020
Anthropogenic noise is a known threat to marine mammals. Decades of research have shown that harbor porpoises are particularly sensitive to anthropogenic noise, and geographic displacement is a common impact from noise exposure.

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.

Programmed unmanned aerial vehicles show great potential for monitoring marine megafauna in specific areas of interest

Remote Sensing in Ecology and Conservation, EarlyView.
Targeted conservation measures are contingent on robust knowledge of spatio‐temporal animal distribution in areas of interest. We explore unmanned aerial vehicle (UAV) transect monitoring as a novel method for standardized digital aerial surveys of marine megafauna by investigating the fine‐resolution spatio‐temporal distribution of harbour porpoises ...
