Which population density affects home ranges of co-occurring rodents?

摘要: Abstract Animal space use patterns can be affected by the intra- and interspecific density of individuals competing for resources, with home ranges generally decreasing increasing population density. By applying spatially explicit capture–recapture models implemented in R package secr, we study whether co-occurring yellow-necked mice, Apodemus flavicollis, bank voles, Myodes glareolus, are related to (a) conspecifics (intraspecific density), (b) other sympatric species, A. flavicollis or M. glareolus (interspecific (c) total rodent (A. plus glareolus). Home both species were negatively intraspecific density, not Given that rodents tend reduce if resources abundant, this pattern may merely result from higher abundance associated high populations, two responding different subsets resources. However, could directly ranges, because more likely interfere each due overlapping patterns. Therefore, results suggest complementary resource between consequent weak competition niche differentiation. Across several years densities, thus appear only, suggesting coexist area owing limited overlap.
