From an ecosystem management perspective, analysis of the functional roles of species is a challenge. It is valuable to determine which species are irreplaceable within a given community based on…
This study presents bioacoustic recordings in combination with movements and diving behavior of three free-ranging harbor porpoises (a female and two males) in Danish waters. Each porpoise was equipped with…
As part of the AMAPPS (Atlantic Marine Assessment Program for Protected Species) project, the Northeast Fisheries Science Center (NEFSC) and Southeast Fisheries Science Center (SEFSC) of NOAA Fisheries Service conducted…
The distribution of marine predators is tightly coupled with that of their prey, and may also be affected by interactions between competing predators. In order to adopt an ecosystem approach…
Cryptococcus gatti is an important infectious disease in the northeastern Pacific. The condition has been associated with significant mortality in harbor porpoise (Phocoena phocoena), Dall’s porpoise (Phocoenoides dalli) and Pacific…
Offshore wind farms (OWF) will soon contribute to significant growth in the renewable energy sector. At present just a few OWF have been built. As of 2012, Germany has an…
The spectacled porpoise (Phocoena dioptrica, Lahille, 1912)is one of the cetacean species about which least is known. Most information on the biology and ecology of this species has been obtained…
Harbour porpoises are the most common small cetaceans in the North Sea and Dutch coastal waters. To study their trophic level and feeding location, stable carbon and nitrogen isotope ratios…
The present study investigated polychlorinated biphenyls (PCBs) and hydroxylated metabolites of PCBs (OH-PCBs) in blood from three porpoise species: finless porpoises (Neophocaena phocaenoides), harbor porpoises (Phocoena phocoena), and Dall’s porpoises…
