Abstract
Since the establishment of the first populations in Buenos Aires province, forests of Celtis ehrenbergiana have been exposed to a severe degradation, yielding a landscape highly fragmentated. The aim of this paper is a) to describe the community of oribatid mites in fragmented forests of C. ehrenbergiana and b) to analyze and compare the structure and composition of oribatid mites community, considering abundance, richness and species distribution in the forest patches versus the surrounding grassland matrix. Samples were collected in two different size patches (M and m) and in the matrix in Nahuel Rucá farm, Buenos Aires. Diversity (H’), species richness (S), evenness (J’) and density were calculated. Species distribution were evaluated through rank-abundance distributions. A total of 59 species, grouped in 50 genera and 34 families, were identified. Hemileius suramericanus was the dominant species in all three sites. Oribatid mites density was 14, 100 ind./m2 in patch M, 4,800 ind./m2 in patch m and 8,800 ind./m2 in the matrix. Species diversity was higher in patches (H’ = 1.3) comparing with the matrix. Evenness was higher in patch m (J’ = 0.8). While in both patches there was no variation in the community structure throughout the year, in the matrix the community structure of spring differed from the rest. Community composition, pattern of species distribution and its relationship with environmental conditions are discussed.
