摘要: The aim of this study was to evaluate whether anthropogenic disturbance in tropical rainforests, the form alteration lower vegetation structure, affects patterns interspecific and intraspecific microhabitat segregation small mammals. We chose two areas a Kenyan rainforest: one disturbed other relatively undisturbed. Rodents were live-trapped with Sherman traps 30 variables measured around each trapping site. Due sample sizes we concentrated our analysis on most abundant species: Praomys jacksoni (De Winton 1897) Hylomyscus stella (Thomas 1911). structured data examine various spatio-temporal scales. First, all available (696 captures — sessions grids both areas) pooled. Step by step large divided into comparisons concerning single areas, (merging sessions) finally grids. species segregate structurally different microhabitats are vertically stratified. In forest there is higher overlap between microhabitats, different, suggesting response reduction variability occurring forest. Intraspecific differential use also found for . discuss juveniles, subadults males segregated poorer quality hypothesize that dynamic.
