The species composition and seasonal dynamics of rat-shaped animal communities on the campus of Zhanjiang Normal College were preliminarily investigated by trapping method from March 2008 to February 2009.The result showed that the dominant species in three different habitats on the campus were Suncus murinus,Rattus norvegicu and Mus musculus,falling into 2 families of 2 orders.The density of S.murinus was the highest in autumn,and that of R.norvegicu was the highest in summer.The percentage of S.murinus was the highest in classrooms,and that of R.norvegicu was the highest in dormitories.The populations of rat-shaped animals were somewhat different in different habitats and seasons but not significantly different.They could be controlled by taking appropriate measures according to seasonal dominant species and density variation.
From March 2008 to February 2009,we used Night trapping method to investigate the ecology of Suncus murinus in Zhanjiang Rormal University.The results showed that the means capture rate of Suncus murinus was 15.40%,the peak was in August.The amphoteric ratio was 1.25∶1.Whole year average pregnancy rate of Suncus murinus was 32.41%,the average enbryo was 3.5.Density and species proportion of Suncus murinus were influenced by some factors,such as environmental condition,climate and poison.Pregnancy rate of Suncus murinus was closely related to climate.
From Match 2008 to Febrary 2009,the research was operated.First,the small animals were caught by ways of night trapping method at 27 spots of 6 kinds of habitats,including the teaching buildings of ZhanJiang normal college,office buildings,dormitories,canteens,greenswards and bushes.Second,the species of the small animals trapped were classified and studied.Conclusion:there live three species of small animals,Rattus norvegicus,Mus musculus and Suncus murinus,in Zhanjiang normal college.Totally,Suncus murinus 485,account for 89.65%,Rattus norvegicus 54,accounting for 9.98% and Mus musculus 2,accounting for 0.37%.Rattus norvegicus is the dominant species.The kinds of min-animals varied in different habitats and months.
