Abstract

In this study we document the spatial and temporal variation in the density of two orb-web spiders (Argiope lobata and A. bruennichi) in the Natural Park of Columbretes islands (Castellón, Spain) during 3 consecutive years (2004-2006). The masive presence of these species was detected for the first time in 2004 in the main island Columbrete Grande (13 ha). From then, we followed their population size. It is very important to document temporal fluctuations in the density of invader species, mainly in small islands occupied by endemic vertebrate and invertebrate species that may suffer higher predation and competition for food.
