Title: Biogeography Research of Conophymacris Willemse
Abstract: Conophymacris Willemse lived only in Yunnan and Sichuan provinces in China.Using cladogram biogeography methods,the biogeography of Conophymacris Willems was researched.The results showed that areas separated two parts obviously;the time maybe in the interval iceage between the second and third iceage,and at the same time there had four separating events totally.Baosan,Gejiou and Zhaotong were earlier areas where separated from other areas.Basing on the areas cladogram,paleogeography,paleogeology,and paleoclimate,the analysis showed genus Conophymacris Willemse had come into being in the first iceage,and the origin area of the genus at the east of Hengduan Mountains,between Sichuan and Yunnan provinces.The species differentiation time was late for the third iceage,mainly before or the late for the Fairy event.The reason of the species differentiation was the temperature fluctuation because of the iceage alternating with the interval frequently.Basing on the biogeography history of Conophymacris Willemse,ecology,the distribution pattern and the development tendency of air temperature today,the conclusion could be inferred that Conophymacris Willemse will go from low height to higher mountain areas,and the distribution areas will narrow.Basing on this fact,the protection of Conophymacris Willemse is very important and urgent today.
