 en Ecological distribution and spatial niche of pheasants in the Karst mountains of southwest Guangxi Province, China
YU, Chen-Xing; YANG, Gang; LI, Dong & ZHOU, Fang

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 check for this species in other resources ), Bar-backed Partridge ( Arborophila brunneopectus check for this species in other resources ), Mountain Bamboo Partridge ( Bambusicola fytchii check for this species in other resources ), Chinese Bamboo Partridge ( Bambusicola thoracica check for this species in other resources ), Red Junglefowl ( Gallus gallus check for this species in other resources ), Silver Pheasant ( Lophura nycthemera check for this species in other resources ) and Common Pheasant ( Phasianus colchicus check for this species in other resources ). 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.
