中国壁虎属的地理分布、形态学和分子系统学研究进展

壁虎属(Gekko)世界报道有47种,中国是壁虎属物种多样性最为丰富的国家,已记载16种.中国壁虎属物种多分布在秦岭以南的热带和亚热带地区,北方种类较少,少数物种可分布至温带,其中11种为中国特有种,荔波壁虎、太白壁虎、文县壁虎、海南壁虎、兰屿壁虎则为分布范围狭窄的地区特有种.目前基于部分线粒体基因和核基因分子标记对中国壁虎属的分子系统学研究已解决许多分类问题,但仍存在较大分歧,种下关系及分类问题尚有待解决.因此,广泛收集中国壁虎属样本,尤其是广布种各地理种群样本,运用多基因联合分析,可有效解决中国壁虎属目前存在的分类和系统关系问题.

Geographical Distribution,Morphology and Phylogeny of Gekko Laurenti in China

According to reports,Gekko genus has 47species around the world and 16species in China which is the most diverse region of Gekko species.The Gekko species in China are distributed most in the tropical and subtropical regions in the south of Qinling mountains,fewer in northern regions of the temperate zone,where there are eleven Chinese endemic species, including G.liboensis、G.taibaiensis、G.wenxianensis、G.similignum and G.Kikuchii in a narrow distribution range.Now, the classification and phylogenetic relationships of Chinese gecko has been made based on partial mitochondrial genes and nuclear molecular markers.However,there is still some controversy concerning taxonomy and relationships among subspecies on genus Gecko.A broader sampling strategy and evidence from additional molecular markers are required to decisively resolve the taxonomy and phylogeny of Chinese gecko.
