Explains how critical information about dispersal and gene flow in sage-grouse populations can be obtained from the DNA coded in the sage-grouse feathers collected at their communal breeding grounds, which are called "leks".
Small wetlands in this large area have hosted migratory birds for a long time, but with changes in agricultural practice and regional climate those habitats may not remain hospitable to the wild populations.

Updated summaries of research in the Arctic National Wildlife Refuge, Alaska, on caribou, muskoxen, predators (grizzly bears, wolves, golden eagles), polar bears, snow geese and their wildlife habitats with maps of land-cover and vegetation.
A geologic and oceanographic study of the waters and Continental Shelf of Gulf of the Farallones adjacent to the San Francisco Bay region. The results of the study provide a scientific basis to evaluate and monitor human impact on the marine environment.
Changes in Arctic sea ice and permafrost will likely affect populations of wildlife. Migratory birds such as loons rely on freshwater lakes in the Arctic for nesting and food supply; we are studying how their populations are affected by these changes.
Loss of sea ice has increased ocean wave action, changing coastal habitats. For some geese this has been a positive change, increasing the amount of coastal area that supports vegetation the geese feed on.
Article from Wildlife Monographs no. 100 (1988) on the relationships of wetland habitat dynamics and life history to the breeding distributions of the various species of ducks with information on research methods and references.
Using satellite telemetry and field studies to track pintail ducks during spring migration north from California's Central Valley plus pintails in New Mexico and Texas. Includes links to migration maps, journal, duck calls, and field methods.
Review of the size of breeding populations of Giant Canada geese by states in the Mississippi, Atlantic, Central, and Pacific flyways and the management problems caused by rapid increases of local breeding populations.
