Size matters: wintering ducks stay longer and use fewer habitats on largest Chinese lakes
Abstract Background Evidence suggests that wintering waterbirds have become conspicuously more concentrated at two largest lakes of the Yangtze River Floodplain, East Dong Ting Lake (Hunan Province, 29°20′N, 113°E) and Poyang Lake (Jiangxi Province, 29°N, 116°20′E), relative to other lakes, despite...
