| Abstract: | The community structure of 15 species of the genus Hydroporus was investigated in various pools with the multivariate software DECORANA, TWINSPAN and CANOCO. Abiotic values measured at 22 bog pools were correlated to DECORANA-data. Typical communities in the Ohemoor (near Hamburg) are related to the factors shaddow, absorption, calcium, and sodium. Data of coexisting Hydroporus species (including other small Dytiscidae, Haliplidae, Noteridae) from 93 pools (near Seedorf/Schleswig-Holstein) could be devided into 4 typical communities (bog, wood, sand-pit, agricultural areas). |
