Assessing the Effects of Banana Pingers as a Bycatch Mitigation Device for Harbour Porpoises (Phocoena phocoena)

Frontiers in Marine Science, 2020
Bycatch is a significant cause of population declines of marine megafauna globally. While numerous bycatch mitigation strategies exist, acoustic alarms, or pingers, are the most widely adopted strategy for small cetaceans.

Emergence, spread, and impact of high‐pathogenicity avian influenza H5 in wild birds and mammals of South America and Antarctica

Conservation Biology, Volume 40, Issue 1, February 2026.
Abstract The currently circulating high‐pathogenicity avian influenza (HPAI) virus of the subtype H5 causes variable illness and death in wild and domestic birds and mammals, as well as in humans. This virus evolved from the Goose/Guangdong lineage of the HPAI H5 virus, which emerged in commercial poultry in China in 1996, spilled over into wild birds,

The nightscape of the Arctic winter shapes the diving behavior of a marine predator

Scientific Reports
Predator–prey interactions in marine ecosystems are dynamically influenced by light, as demonstrated by diel vertical migrations of low-trophic level organisms.

Clicking for supper

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

Seasonal Abundance and Distribution of Cetaceans in a High Traffic Shipping Corridor

Marine Mammal Science, Volume 42, Issue 1, January 2026.
ABSTRACT The recovery of many cetacean species coincides spatially and temporally with intensifying anthropogenic threats. We undertook multi‐year systematic surveys to quantify seasonal abundance and document the distribution of at‐risk cetaceans, which is needed to assess the impacts of increasing human activities in the Canadian portions of the ...

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

Frontiers 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.

Growth of the harbour porpoise (Phocoena phocoena) in eastern Newfoundland, Canada

NAMMCO Scientific Publications, 2003
Although the stock relationships among harbour porpoise (Phocoena phocoena) in the Northwest Atlantic are unknown, it has been postulated that there are 4 local populations: Bay of Fundy/Gulf of Maine, Gulf of St.

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

Frontiers 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 ...

Tracing Time's Footprints: Exploring Feeding Ecology and Historical Changes of Mediterranean Common Dolphin (Delphinus delphis) Over Two Centuries

Marine Mammal Science, Volume 42, Issue 1, January 2026.
ABSTRACT The Mediterranean common dolphin (Delphinus delphis) presents an enigmatic natural history during the past centuries. Widely prevalent in the 19th and early 20th centuries, it faced a significant decline across most of the basin by the late 1960s caused by multiple anthropogenic threats, including culling, bycatch, prey depletion, and habitat ...
