Relation of highly pathogenic avian influenza (H5N1) prevalence to migration patterns of Pacific common eiders nesting in Northwest Alaska
To examine relationships between highly pathogenic avian influenza prevalence and migration patterns of Pacific common eiders (Somateria mollissima v-nigrum) nesting in Northwest Alaska, we marked 25 adult Pacific common eiders (24 females and 1 male) from the Cape Espenberg breeding area (28 June-7 July 2007) with satellite transmitters and sampled individuals for highly pathogenic avian influ...
متن کاملMicrosatellite and mtDNA analysis of lake trout, Salvelinus namaycush, from Great Bear Lake, Northwest Territories: impacts of historical and contemporary evolutionary forces on Arctic ecosystems
Resolving the genetic population structure of species inhabiting pristine, high latitude ecosystems can provide novel insights into the post-glacial, evolutionary processes shaping the distribution of contemporary genetic variation. In this study, we assayed genetic variation in lake trout (Salvelinus namaycush) from Great Bear Lake (GBL), NT and one population outside of this lake (Sandy Lake,...

متن کاملBreeding Ecology of Sympatric Greater and Lesser Scaup (Aythya marila and Aythya affinis) in the Subarctic Northwest Territories
We studied the breeding ecology of greater and lesser scaup on islands of the North Arm of Great Slave Lake, Northwest Territories, and on the nearby mainland during 1990 – 98. The occurrence of nests of both species on the North Arm islands was determined primarily by the distribution of nesting gulls and terns and secondarily by habitat features. Nest parasitism was frequent on the islands, b...
متن کاملReproduction biology of chub living in Lake Hafik
In this study, the reproductive biology of chub population in Hafik Lake was investigated. 242 samples were caught between April and November 2009. The age of S. cephalus samples were found to range between I-VIII in addition, 153 of them were female and 89 were male. Their fork lengths changed between 114-332 mm, and body weights were between 22.5 and 550.3 g. Male specimens were determined t...
