Sperm competition in the scorpionfly Panorpa communis (Mecoptera, Insecta)
(2007)
The aim of the present study was to investigate the basal mechanism of sperm competition in the European scorpionfly Panorpa communis. Within three laboratory experiments, I used five newly developed microsatellite ...
Nuptial feeding in the scorpionfly Panorpa vulgaris: ultimate and proximate causes
(2005)
In my thesis I was concerned with ultimate as well as with proximate aspects of nuptial feeding in the scorpionfly Panorpa vulgaris (Mecoptera: Panorpidae). Chapter I begins with the attempt to verify the ultimate function ...
