Last Update: 2016-05-24
Larus Gull Microsatellite DNA Data, 2006-2009

This data set describes nuclear microsatellite genotypes derived from eleven autosomal loci (Hg16, Hg18, Hg25, K16, Lar12, Lar19, Lar24, Lar26, Rbg13, Rbg18, and Rbg29). A total of 651 Larus gulls were examined for this study with samples collected throughout North America, Europe, Russia, and South America.

Waterfowl Counts and Wildfire Burn Data from the Western Boreal Forest of North America, 1955-2014

The project utilized data from the Waterfowl Breeding Population and Habitat Survey, which is an annual survey conducted since 1955 by the governments of the United States and Canada to monitor waterfowl populations. These survey data were spatially and temporally layered onto long-term databases of fire perimeters for Alaska and western Canada, providing a record of waterfowl transects which had burned over the last 60 years. The project modelled abundance of dabbler and diver pairs in relation to time since fire, looking at short-term (e.g., 13 years) versus long-term timeframes (e.g., >5 years), and in relation to fire extent, defined as the percent of transect which had burned.

Stable Isotope Data from Diets and Tissues of Captive Bears Fed Experimental Diets

This dataset contains stable isotope incorporation and discrimination results for several sets of feeding experiments with captive brown and polar bears. Experiments were designed to determine the effects of dietary lipid content and fasting behavior on discrimination in blood, hair, and fat. Data are divided into three components of the study: one to estimate isotopic discrimination with varying dietary lipid content, one to estimate the potential effects of fasting on tissue isotope values, and one to determine incorporation rates of isotopes in various tissues. The experiments were conducted between 2009 and 2013 with captive grizzly bears at Washington State University and captive polar bears at the Oregon and Alaska zoos.
