Bluefish Caves (Figure 1), located 54 km southwest of the village of Old Crow in northern Yukon has yielded evidence of episodic human activity from about 25,000 to 12,000 BP (radiocarbon years before present). It may be the most significant of Late Pleistocene Eastern Beringian and Canadian cave faunas because the caves contain: (1) in situ evidence for the earliest people in North America; (2) a well-marked transition between Pleistocene (approximately 2 million to 10,000 years ago) and Holocene (about the last 10,000 years) sediments, flora and fauna; and (3) remains of a substantial variety of both smaller and larger mammals adapted to northern conditions, as well as migratory birds, that lived during the last...

An ecological assessment of the Sambaa K'e Candidate Protected Area (SKCPA) and vicinity is required as part of the Northwest Territories Protected Area Strategy. This report presents the results of an aerial survey that was conducted in March 2009 as part of the Phase 2 ecological assessment. It includes observations of moose, boreal caribou, beaver, wolf, and wolverine.--Includes text from document.

Estimates of gene correlations among individuals within and among populations are frequently derived from statistical analyses of genetic data (e.g., F statistics). These measures can be important tools in molecular ecology and conservation, and offer important insights into population breeding structure. Using recently derived theory developed for group-structured populations, we show that fixation indices, when combined with basic population ecological and demographic data can be used to investigate population mating systems and to predict dispersal rates, trajectories and asymptotic levels of fixation indices, and effective population size. Four case studies of poikilothermic vertebrates are used to demonstrate...
