Abstract

AbstractThe epigeic spider communities of the Western Carpathians are characterised by a high number of species. The great influence of Pannonian elements on the coenoses of the Carpathian hills is evident. The habitats of the Western Carpathians differ from each other, and several types of microclimatic conditions are there. These facts affect the spider fauna. The epigeic spider communities of the western part of the Carpathians, represented by the Devínska Kobyla hill, were characterized by the constant presence of four species at all study sites — Dysdera erythrina, Agroeca cuprea, Pardosa lugubris and Trochosa terricola. Principal components analysis confirmed the high proportion of Trochosa terricola, Eresus moravicus and Scotina celans in the epigeic spider community of the steppe. In contrast, the presence of Coelotes inermis, Histopona torpida and Haplodrassus silvestris was important in the oak forest. Bray-Curtis analyses confirmed that the spider community of the oak forest differed. The migration and penetration of the species with high vagility was an important fact that affected the spider community in the ecotones. Based on the analysis of the araneocoenoses in the Western Carpathians, spiders were grouped into four categories — leaders, typical spiders, specific spiders and tourist species.
