摘要:

2008年至2014年对河南伏牛山区进行野外考察,陆续发现、采集一批臭蛙属(Odorrana)标本,经形态学比较、系统聚类分析及12SmtDNA序列比对,分别为花臭蛙(O.schmackeri)与合江臭蛙(O.hejiangensis).河南南召为合江臭蛙已知分布北限,与模式产地四川合江相距近5个纬度,与合江臭蛙已知分布区呈间断分布,这种分布格局的形成与地质结构变迁、气候及水系演变的关系值得探讨.河南南召合江臭蛙繁殖季节较模式产地四川合江种群晚一个月左右,与同域分布的近缘种花臭蛙存在明显的繁殖季节隔离.两个近缘物种同域分布,其同域和物种分化的机制有待进一步研究.

Field surveys were conducted in Funiu Mountain during 2008 to 2014,and specimens of the genus Odorrana were collected.Analysis of morphological features,systematic clustering and alignment of 12 S mtDNA data suggested the specimens were O.schmacheri and O.hejianggensis,respectively.Nanzhao County,Henan province,is the northmost distribution boundary of O.hejianggensis,far away from its type locality Hejiang County,Sichuan province,near five latitude.In addition,it is also suggested the discontinuous distribution pattern of O.hejianggensis based on their documented distribution range.And further studies should be to explore the relationship between the formation of this distribution pattern and the geological tectonic events,climate fluctuation and drainage rearrangements.Furthermore,it is also suggested the breeding season for O.hejianggensis in Nanzhao was a month later than those from the type locality,and different breeding season were observed obviously between them and O.schmacheri in their sympatric distribution areas,whereas the mechanism underlying the sympatric distribution and speciation within the related species remain unknown.
