While harbor porpoises currently enter San Francisco Bay year‐round, evidence suggests a disappearance that spanned approximately 65 yr. The range of energetic costs of basal metabolism, locomotion, thermoregulation, and reproduction…
Unlike terrestrial mammals that have unambiguous aerial sound transmission pathways via the outer ear and tympanum, sound reception pathways in most odontocetes are not well understood. Recent studies have used…
This study was carried out to determine stranding levels, dead reasons and some reproduction features and diet of the Black Sea’ cetacean species (harbour porpoise, Phocoena phocoena and common dolphin,…
It is a tradition that regular overviews are published of strandings of cetaceans. The last overviews for Belgium covered the period 1975 to 1989 and 1990 to 1994. This overview…
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…
Determining management units for natural populations is critical for effective conservation and management. However, collecting the requisite tissue samples for population genetic analyses remains the primary limiting factor for a…
The effects of tagging on small cetaceans are difficult to assess due to logistical difficulties in recapturing the whales. In this study two narwhals, Monodon monoceros, and five harbor porpoises,…
B-cell lymphoma, a common morphologic variant of non-Hodgkin lymphoma, has been associated with persistent pollutants in humans, but this association is not well-characterized in top-level predators sharing marine resources with…
The ecological value of the stranding record is often challenged due to the complexity in quantifying the biases associated with multiple components of the stranding process. There are biological, physical…
(...)The occurrence of solitary dolphins (i.e., those in isolation from conspecifics) is well-documented in the case of bottlenose dolphins (Tursiops truncatus) along the western seaboard of northern Europe (Lockyer, 1990);…
