Abstract:	The paper presents the taxonomical and numerical structure of the gamasid populations from four spoilt areas from Retezat and Tarcu-Petreanu mountains. Eighteen species were identified, belonging to 14 genera and 9 families. Species Cheroseius borealis and Hypospis aculeifer were dominant and present in all studied surfaces. The mite populations had structural and dynamical differences, caused by the various environmental conditions (like vegetation, soil humidity and pH). To evidence these modifications were analysed the following statistical parameters: number of species, numerical density, relative abundance, dominance, constancy. Comparative with predator mite populations from the natural ecosystems, the values of these parameters obtained for gamasids from the spolit areas were very low. It shows that in anthropized ecosystems the influence of the specifically biotic and abiotic factors on the mite populations was significant.
Keywords:	spoilt area, mite, population, dominance, constancy
