The food of the Pacific white-sided dolphin, Lagenorhynchus obliquidens, and Dali's porpoise, Phocoenoides dalli -- collected off California and Washington in 1958-72 -- is compared with food of the northern…
The liver can be an indicator of the health of an individual or of a group, which can be especially important to identify agents that can cause disease in multiple…
Harbour porpoises in the Bay of Fundy and Gulf of Maine feed primarily on Atlantic herring. Herring stocks have undergone dramatic fluctuations in abundance over the past three decades due…
Harbor porpoise bycatch estimates for federally managed gillnet fisheries in northwestern Atlantic US waters were calculated for a nine-year period (1999–2007) using two new methods, and the results were compared…
Morphology of the modern cetaceans represents the results of adaptation of the ancestral terrestrial mammals to aquatic life through their evolutional processes. Some of the primitive fossil cetaceans are known…
During the evolutionary transition from land to water, cetaceans have undergone numerous critical challenges, with osmoregulation being the major one. Two subspecies of the narrow-ridged finless porpoise (Neophocaena asiaeorientalis), the…
Examination of 95 Dall's porpoise specimens incidentally caught in gill nets, and 4 collected as beach strandings, indicate significant sexual dimorphism and developmental variation in several aspects of external morphology…
Testicular and ovarian development in neonatal and juvenile harbour porpoises Phocoena phocoena was examined, using tissue from animals (males n= 65 and females n= 10) stranded or caught off the…
Knowledge about parasitism in harbour porpoises and their health status around Greenland is scarce. This study provides knowledge about the poorly studied cetacean in its rapidly changing environment. Parasites and…
Hearing sensitivity, during trials in which a warning sound preceding a loud sound, was investigated in two harbor porpoises (Phocoena phocoena). Sensitivity was measured using pip-train test stimuli and auditory…
