Bird Observations at Rankin Inlet, Northwest Territories

Radar Observations of Arctic Bird Migration at the Northwest Passage, Canada

Bird migration was recorded by tracking radar and visual observation at 23 sites in the region of the Northwest Passage, between Baffin Island and Herschel Island in the Beaufort Sea. The studies took place during a ship-based expedition from 29 June to 3 September 1999. A total of 692 tracks (average duration 160 s) of bird flocks on postbreeding migration were recorded. Eastward migration was...

Bird territories: A key to understanding bird behavior

Amphibian chytrid fungus and ranaviruses in the Northwest Territories, Canada.

Pathogens can cause serious declines in host species, and knowing where pathogens associated with host declines occur facilitates understanding host-pathogen ecology. Suspected drivers of global amphibian declines include infectious diseases, with 2 pathogens in particular, Batrachochytrium dendrobatidis (Bd) and ranaviruses, causing concern. We explored the host range and geographic distributi...

New olenelloid trilobites from the Northwest Territories, Canada.

The Olenelloidea are a superfamily of early Cambrian trilobites, which have been the subject of several phylogenetic analyses and also used to address macroevolutionary questions regarding the nature and timing of the Cambrian radiation. The Sekwi Formation of the Mackenzie Mountains, Northwest Territories, Canada, has yielded numerous species from this clade, and here we present new informatio...

The site appears to date to within the second half of the 19th century, following European contact but before acculturative processes and population decline, which brought about the extinction of traditional Mackenzie Inuit culture.
