Abstract:The selection of different spatial scales is critical when investigating ecological processes, because different patterns emerge in spatial data at different scales. The wintering habitat selection of Brown-eared Pheasant Crossoptilon mantchuricum was studied on four spatial scales (10m, 100m, 300m and distance scale) in Luyashan Nature Reserve of Shanxi from 1998 to 2000. At the 300m scale, the area of coniferous forests around selected sites was larger than that of unselected sites (F=(-3.116,)P=0.002), a...
