Testing for the relative contribution of patch neighborhood, patch internal structure, and presence of predators and competitor species in determining distribution patterns of rodents in a fragmented landscape

摘要: Factors affecting the distribution of species in fragmented landscapes, and their relative importance, are often unclear. Few studies have deliberately compared various hypotheses relatively controlled conditions. Moreover, most to date not incorporated false absences modeling. Following a multiple testing framework, we tested role landscape structure, patch neighborhood configuration, internal presence or absence predators, abundance potential competitor on occupancy patterns three rodent (Myodes glareolus (Schreber, 1780), Apodemus flavicollis (Melchior, 1834), sylvaticus (L., 1758)) highly Tuscany, central Italy. Distribution dynamics were affected by characteristics, as well vicinity other patches occupied species. However, found no relev...
