In this study we showed that the previously unstudied 'eunuch phenomenon' in spiders is adaptive. Males of the sexually dimorphic species Nephilengys malabarensis break their copulatory organ during copulation and thus become sterile and this behavior correlates with eunuch's enhanced aggression. Eunuchs thus monopolize a female, which hints at adaptation in response to sperm competition.

In this publication, which attracted media attention, we reported on behavioral adaptations for riverbridging webs in the spider Caerostris darwini (Araneae: Araneidae) from Madaagscar.

The work deals with the confrontation of two approaches in vegetation science: gradient analysis and classification of communities. In several case studies it was tested whether samples are arranged along gradients according to the individualistic or the integrative concept. The results show that, in most cases, the turnover of species composition along the gradient, according to the integrative concept, is due to species interactions. This enables us to detect and describe discrete plant communities in terms of the central European Braun-Blanquet method.
