5. CURRENT ABUNDANCE OF ADÉLIE PENGUIN BREEDING POPULATIONS ALONG THE KEMP AND MAC.ROBERTSON LAND COASTS, EAST ANTARCTICA: APPLICATION OF NEW SURVEY AND ESTIMATION METHODS FOR BROAD-SCALE POPULATION ASSESSMENT

   Abstract:  Application of new methods for estimating the abundance of breeding Adélie penguin ... populations along the Kemp and Mac.Robertson Land coasts of east Antarctica are described. Methods include use ... availability using ICESCAPE software. The surveys revealed a considerably larger population of Adélie penguins ... breeding in this region than was previously known.
