Importanța structurii și stabilității ecosistemelor în contextul relațiilor biocenotice și a menținerii diversității comunităților de mamifere

Abstract

The purpose of the paper is to elucidate the importance of the structure and stability of ecosystems and biocenotic relationships in maintaining the diversity of mammal communities. In the ecotone zone of forests at the edge of perennial plantations, in orchards and vineyards, the index of diversity of rodent mammals is maximum (H '= 1.43). The most affected by the anthropogenic factor, but also by the climate changes of the last decades, natural ecosystems are the marshy and aquatic biotopes (H '= 0.42). An increased value of the diversity parameter was determined for the mammal communities in the natural shrub-tree ecosystems (H '= 1.75-2.46).
