title: [Ecological distribution and spatial niche of pheasants in the Karst mountains of southwest Guangxi Province, China].
abstract: The Karst mountain area along the Sino-Vietnam border of southwest Guangxi has been designated a "Global Biodiversity Hotspot" since 2003. We conducted a survey of pheasant species in this area, with seven species recorded, namely Chinese Francolin (Francolinus pintadeanus), Bar-backed Partridge (Arborophila brunneopectus), Mountain Bamboo Partridge (Bambusicola fytchii), Chinese Bamboo Partridge (Bambusicola thoracica), Red Junglefowl (Gallus gallus), Silver Pheasant (Lophura nycthemera) and Common Pheasant (Phasianus colchicus). Analysis and comparison of the distribution and spatial niche of these seven pheasant species revealed that Red Junglefowl had the widest spatial niche, while Chinese Francolin had the narrowest. The spatial niche overlap index was high between Chinese Francolin and the Common Pheasant, Chinese Bamboo Partridge, and Red Junglefowl. With narrow distribution range, small population, and lower ecological adaptability, it is likely that the Bar-backed Partridge is the most vulnerable pheasant species in this area. The results suggest more research and conservation measures are required for pheasant habitat protection in the Karst areas of southwest Guangxi.
