Abstract:Study was made of the effect exerted on the reproduction of spider Enoplognatha ovata (Clerck) by forest island ecotones and their differentiation resulting from island size, type of vegetation and exposure (southern and northern ecotones). Evaluation was made of female density and numbers of cocoons, as well as of female fecundity characterized by the following indices: cocoon size (number of eggs laid), cocoon validity (percentage of fertilized eggs) and cocoon viability (percentage of young spiders which left the cocoon). Reproduction losses at the embryonic development stage in the cocoon, caused by embryo mortality, were calculated. The birch-aspen woodlot ecotones and ecotones with southern exposure, as compared with the Pino-Quercetum forest island ecotones, were characterized by higher individual fecundity and smaller losses in E. ovata reproduction. The differences between the ecotone and forest island interior in spider reproduction were more clear-cut in the case of the larger islands (13.5 ha).
