(...) Sound emissions by odontocetes (toothed whales and dolphins) can be classified into two broad categories of frequency-varying continuous tonal sounds referred to as whistles and broadband clicks (Evans, 1967),…
A yearling male harbor porpoise (Phocoena phocoena) stranded alive on the shores of Avon, North Carolina, and was rehabilitated for nearly 10 mo at the National Aquarium in Baltimore and…
Regular monitoring of the status of cetacean populations is essential for conservation, policy and management. By using a passenger ferry as a scientific research platform, this study provides information on…
With the United Kingdom required to designate Special Areas of Conservation (SACs) under Natura 2000 by 2012, it is important to understand site-specific activity and habitat use in order to…
The harbour porpoise (Phocoena phocoena) is an important top predator and as such an indicator species for its environment. Before the beginning of the 21st century, little data existed on…
The 50% detection hearing thresholds of a harbor porpoise for a 4.0 kHz narrow-band FM signal, presented at the background noise level in a pool and with two masking noise…
To gain insight into the time allocation and diving behaviour of harbour porpoises in Danish and adjacent waters, satellite linked dive recorders were mounted on 14 harbour porpoises. The animals…
The distribution of harbour porpoises Phocoena phocoena in southern Europe and along the Atlantic African coast is poorly understood, with tentative assessments suggesting a discrete West African population with a…
In small birds, mass-dependent predation risk (MDPR) is known to make the trade-off between avoiding starvation and avoiding predation dependent on individual mass. This occurs because carrying increased fat reserves…
We investigated the feeding ecology and habitat use of 32 harbour porpoises by-caught in 4 localities along the Scandinavian coast from the North Sea to the Barents Sea using time-integrative…
