sightings recorded during systematic marine mammal surveys conducted in Cook Inlet, Alaska, 1978-2012.
gattii since 2000 was diagnosed in 15 harbor porpoises
, 10 Dall's porpoises, 2 adult Pacific white-sided dolphins, and 3 unrecorded species (10 females, 15 males, and 5 unknown sex; 24 adults, 4 juveniles, 1 fetus, and 1 undocumented age; S.
Small group sizes and low surfacing profile also made detection of northern right whale dolphins and harbor porpoise
difficult, and northern right whale dolphins were only observed in mixed-species groups.
ceti infection and associated lesions in a harbor porpoise
found on the coast of Belgium in 2008.
2 to produce a correction factor for perception bias that was specific to harbor porpoise
in Alaskan waters and to the surveys presented here and to develop methods to test observer performance, by using data collected during these surveys; and
Total number of linear and square kilometers surveyed in lower Cook Inlet and harbor porpoise
sighting rates during marine bird and mammal surveys, 1995-99.
Blood samples (anticoagulated with EDTA) were obtained from a live, stranded yearling female harbor porpoise
(Phocoena phocoena) that required humane killing in northern North Carolina in May 2005 (MLC 001) and from a yearling male harbor porpoise
We also noted the absence of six regularly observed species: harbor porpoise
, gray whales, Pacific white-sided dolphins (Lagenorhynchus obliquidens), Risso's dolphin (Grampus griseus), harbor seals, and California sea lions (Zalophus californianus).
Today, NMFS recognizes (and manages separately) four stocks of harbor porpoise
along the U.
strandings classified as HI-FI occurred in February (n=3), March (n=3) and April (n=5).
We have examined larger animal population dynamics in considering the effect of the sink gillnet fishery on the Gulf of Maine harbor porpoise
population and are currently seeking funding to analyze the populations of the North Atlantic right whale, the most endangered of the large whales.
Our results could also be used in further risk assessment models for population-level effects where dose-response data are difficult to obtain for free-living marine mammals such as the harbor porpoise
In one case, witnesses report a group of bottlenoses ramming a sole harbor porpoise
with their heads and long snouts, sending it flying into the air.
Additional evidence that harbor porpoise
restrict their movements has been obtained from both contaminant research and satellite tagging studies.
Two marine mammal species that live there year-round are the beluga whale, Delphinapterus leucas, and the harbor porpoise
, Phocoena phocoena.
