Aspecte ale structurii și diversității comunităților de mamifere din rezervaţia ştiinţifică „Pădurea Domnească” [Articol]

Abstract

Aspects of the structure and diversity of communities of mammals from the scientific reserve "Padurea Domneasca". Research in the "Pădurea Domnească" reserve was carried out during the years 1995-2023. A rich diversity of the mammal fauna was confirmed, consisting of about 30 species. In the reserve, the value of the edge effect index in the meadow biotope is 0.19, and in the forest - 0.41. The following share of rodents was established according to the predilection for the biotope: meadow – 30.4%, ecotone – 47.4% and forest – 22.2%. If in spring the Simpson index was respectively in the meadow – 0.312; ecotone – 0.404 and forest – 0.379, later, in the autumn period, an increase in this index was recorded, the diversity being respectively 0.578; 0.852; 0.422.The diversity of mammals during the last 30 years decreases from 1.97 to 1.62. It was established that both the specific composition and the spatial distribution of mammals on the territory of the reserve demonstrate a wealth of ecological niche diversity. The reserve has a special social and economic value, and its protection measures need to be intensified.
