Duration of stay (ln(1 + x) transformed) for individual GPS-tracked dabbling ducks of three species, recorded at each lake used in the Yangtze River floodplain, eastern China, in relation to a lake inundation area (ln(1 + x) transformed km2, upper graphs) and b water area (ln(1 + x) transformed km2, lower graphs) in winter
