Ermittlung charakteristischer Spinnengemeinschaften von Biotoptypen am Beispiel der nordwestdeutschen Küstenregion

A classification method for ascertaining characteristical spider communities of different biotope types is presented. Based on a current list of biotope types all data available from a certain area about the spatial distribution of spiders were fed into a data bank an analysed. A largely standardized method has been developed which allows to classify the spider community of each biotope type. The classification is based on a presence/absence matrix and a comparison between the grades of presence in different biotope types.
