四川青川县地震灾后鼠类群落结构及其动态
Community Structure and Dynamics of Rodents After Great Earthquake in Qingchuan of China's Sichuan
摘要
Abstract
[Objective] The objective of this study is to detect population dynamics and community structure of rodents in Qingchuan County after earthquake happened on May 12,2008,and to prevent pest outbreak in this county.[Method] Regular quarterly surveys were conducted on rodents by the night trapping method in woodland and farmhouse in Qingchuan County of Sichuan Province from October 2009 to October 2011.[Result] A total of 190 individuals from 5570 traps were collected,which were identified to 11 species and belonged to two categories (Rodentia and Soricomorpha).The trapped rodent species in Qingchuan County were Rattus norvegicus,R.nitidus,R.tanezumi,Niviventer confucianus,Leopoldamys edwardsL Mus musculus,Apodemus draco,A.chevrieri,Micromys minutus,Eothenomys melanogaster,Crocidura attenuate.Succession of rodent community was characterized by the change of dominant species from R.nitidus to R.tanezumi in the farmhouse.The relative population density of R.nitidus presented a descend trend before April 2010,and for the R.tanezumi,the relative population density increased continuously after July 2010.C.attenuata and A.draco were two dominant species in woodland.The A.draco density varied periodically during the whole investigating period.The C.attenuata density declined before April 2010,and then varied periodically with a low density.L.edwardsi and A.chevrieri were captured for the first time in October of 2010,and then A.chevrieri became one of the dominant species in the woodland.Shannon,Simpson,Pielou and Margalef indices of rodent community in farmhouse changed greater than those in woodland.[Conclusion] The rodent community structure in farmhouse changed greater than that in woodland after the great earthquake.The R.tanezumi density in farmhouse showed an increasing tendency after July 2010.Long-term monitoring of house mouse,especially R.tanezumi,will likely need to be carried out in farmhouse.关键词
