- The xylobiontic beetle fauna of old oaks colonised by the endangered longhorn beetle Cerambyx cerdo Linnaeus, 1758 (Coleoptera: Cerambycidae) (2008)
- In our present-day landscape in Central Europe major parts of the xylobiontic especially of the saproxylic beetle fauna belong to the group of endangered species assemblages (Speight 1989, Geiser 1994). Oaks, in Central Europe mainly Quercus robur and Q. petraea, are well known for their large number of associated insect species and harbour the highest beetle diversity, especially for dead wood inhabiting species, of all broadleaved tree species in this region (e.g. Palm 1959). A characteristic species associated with oaks in its life-cycle is the endangered Great Capricorn Cerambyx cerdo. C. cerdo is one of the protected species explicitly named in the Habitats Directive of the European Union with the goal of maintaining existing populations and establishing long-term survival (Council of the European Communities 1992). The last remaining colonised areas of this longhorn beetle in Central Europe are well known for the enormous number of very rare xylobiontic beetle species. Thus, we are interested in the following research questions: 1) Are there typical species associated with C. cerdo? 2) If so, what kind of relationship do these associated species have to C. cerdo from a nature conservation point of view?
- Zur Bestimmung von Cicindela hybrida LINNÉ 1758 (Coleoptera, Cicindelidae) (1983)
- In Nordwestdeutschland kommen Tiere des Sandlaufkäfers Cicindela hybrida vor, die eine ausgedehntere Behaarung der Stirn aufweisen als andere Vertreter dieser Art. Auch die Form der Mittelbinde auf den Flügeldecken erinnert manchmal sehr an Cicindela maritima. In tabellarischer Form werden Unterscheidungsmerkmale für nordwestdeutsche Käfer beider Arten angegeben.
