| Abstrakt: | Abstract: Between 2000 and 2005 the epedaphic collembolan community on different islands and in different riverbank habitats of the nature protection area "Inselrhein near Mainz", Germany, were investigated. Altogether 53,915 individuals belonging to 11 families and 43 species were caught using pitfall traps. In contrast to the periodic flooding in spring 2001 and 2002 the extremely dry and hot summer of 2003 caused an immediate decrease in the number of species and average numbers of individuals. The mesophilic and more xerotolerant species, like Pogonognathellus flavescens (Tullberg, 1871), Orchesella cincta (Linnaeus, 1758) and Orchesella villosa (Geoffroy, 1762), showed a rapid recovery. These species are better adapted to drought conditions and in the absence of the other species rapidly increased in abundance. The species composition of the communities on the islands and riverbanks were clearly different before the extreme drought in 2003. After this event the communities were very similar. Compared to the effects of periodic spring floods the extreme summer drought in 2003 had a greater and longer lasting effect on the whole collembolan community. |
