Social delphinids employ a vocal repertoire of clicks for echolocation and whistles for communication. Conversely, the less social and acoustically cryptic harbour porpoises (Phocoena phocoena) only produce narrow-band high-frequency (NBHF)…

The harbour porpoise (Phocoena phocoena) is a highly mobile cetacean found across the Northern hemisphere. It occurs in coastal waters and inhabits basins that vary broadly in salinity, temperature and…

...In the course of the pioneer virtopsy-driven stranding response program in Hong Kong (HK) waters, virtopsy using postmortem computed tomography (PMCT) has been implemented to augment conventional necropsy. A growing…

Cetaceans are an important component of marine biodiversity, as apex predators, cetacean abundance and distribution are key indicators of environmental status, such as food web integrity. Five species of cetacean…

Harbour porpoises Phocoena phocoena are common in continental shelf areas of the North Atlantic, but little information is available on their occurrence outside coastal areas. In this study, 30 harbour…

Seasonal changes in food consumption, respiration rate, and body condition in a healthy captive male harbor porpoise (Phocoena phocoena) from the North Sea were recorded over 8 y. He was…
Methods in Ecology and Evolution (2018)
Passive acoustic monitoring (PAM) is used for many vocal species. However, few studies have quantified the fraction of vocalisations captured, and how animal distance and sound source level affect detection…

Harbor porpoises (Phocoena phocoena) are commonly observed in Oregon's nearshore marine environment yet knowledge of their ecosystem use and behavior remains limited, generating concerns for potential impacts on this species…

The Golden Gate Bridge in San Francisco Bay provides a non-invasive aerial platform where harbor porpoises (Phocoena phocoena) can be observed mating. We photographed 144 mating events over an eight-year…

Naval sonar signals may affect the behavior of harbor porpoises (Phocoena phocoena). The 53C sonar system produces 1,600 ms sonar signals in the 3.5 to 4.1 kHz band, each consisting…
