Long-tailed Duck (Clangula hyemalis) Microsatellite DNA Data; Alaska, Canada, Russia, 1994-2002
This data set describes nuclear microsatellite genotypes derived from twelve autosomal loci (6AB, Aph02, Aph08, Aph19, Aph23, Bca10, Bca11, Hhi5, Sfi11, Smo07, Smo09, and CRG), and two Z-linked microsatellite loci (Bca4 and Smo1). A total of 111 Long-tailed Ducks were examined for this genotyping with samples coming from the two primary breeding locales within Alaska (Arctic Coastal Plain of Alaska and the Yukon Delta, Western Alaska) and a representative locale in the central Canadian Arctic (Queen Maud Gulf Bird Sanctuary, Nunavut, Canada). The sex of most samples was determined in the field by plumage and later confirmed by using the CHD molecular sexing protocol (Griffiths et al., 1998).

Recreation Survey Results in Brown Bear Habitats, 2013
These data are the results of a modified Delphi survey in which expert opinion was solicited on the occurrence and frequency of recreational activities in brown bear habitats and their potential impacts. Twelve bear experts were surveyed and identified by either 1) their scientific publications on the impacts of one or more human recreational activity on bears, or 2) their experience in managing bear populations impacted by human recreational activities. Respondents were asked to estimate the frequency of each identified recreational activity for the bear populations they have experience with, estimate the proportion of each specific bear population exposed to each activity, and indicate the potential impacts of recreational activities in those bear populations. The frequency of occurrence of a recreational activity category and the proportion of the bear population exposed are reported from the final survey. We report the percentage of experts that noted potential for an impact on reduced survival, decreased nutritional intake, displacement, and reduced reproduction.

Chukchi Sea Polar Bear Location Data 1985-1996
These data are the raw location data collected from satellite radio-collars fitted on adult female polar bears in the Chukchi Sea, between 1985-1996. The collars were worn by adult female polar bears ranging within the Chukchi Sea subpopulation boundaries as identified by the International Union for the Conservation of Nature’s Polar Bear Specialist Group. ARGOS collars were programmed to transmit for 8 hours centered on 0:00 UTC once every three days. Thus, for two consecutive days the ARGOS collar did not transmit location data.
