Bird banding is used to study the movement, survival and behavior of birds. The Bird Banding Laboratory Site has links to the value, procedure and history of bird banding, how to report bird bands (English & Spanish), and resources for birders.
Geographical access to multiple bird checklists developed by others that indicate the seasonal occurrence of birds in a given area. A Record Documentation Form to document supporting details of rare bird observations is also available.
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".
Combining genetic data with current and predicted climate scenarios, we are modeling the predicted future distributions of wildlife populations in the Arctic and identifying key environmental variables that determine important animal habitat.
Polar bears are endangered by reduction in Arctic sea-ice concentration and by reduction in their supply of prey for food. Models shown here indicate anticipated effects on polar bear populations of several climate change scenarios.
