瑞士西部农田周围生态保留带中小型兽类种群结构特征及数量动态的初步研究
The Population Structure and Dynamics of Small Mammals in Set Aside Areas in Western Switzerland
摘要
Abstract
In this paper in order to assess the effect of set aside to small mammal populations, one year field study using mark and recapture method was performed in set aside fields in Salavaux, Chevroux and Montbrelloz in western Switzerland. There are 3 species were regularly caught in the set asides: the common vole(Microtus arvalis), the white toothed shrew(Crocidura russula), and the wood mouse(Apodemus sylvaticus). The common vole was the most numerous species in the three set aside fields. Population size of common voles was different between the set aside, but fluctuations in animal numbers were similar, showing a rapid increase as cover and food abundance increased in the set asides during late spring, leading to peak in midsummer. The age structure differed between males and females, most individuals captured during this study are adults and subadults. There were more subadult males than female and more adult females than males (x2 =44.09, df=10,P＜0.001,N=203). There was a significant difference in body mass between the sexes among common voles, males were significantly heavier than females(t-test unequal variances: t=5.011, df= 162, P＜0.05,N=213). The sex ratio was very different for the different months, females being more frequently captured than males and there was no similarity between the set asides. The home range size of common voles lied between 350 and 400 m2; the individuals move only short distances and there were no significant differences between males and females.关键词
