What is Assemblages of Dytiscid Predators and Culicid Prey in Relation to Environmental Factors in Natural and Clear-cut Boreal Swamp Forest Pools about?

Assemblages of diving beetles (Dytiscidae) and mosquito immatures (Culicidae) were studied during 1987-1988 in 40 small, more or less temporary, snowmelt pools in spruce swamp forest and clearings at the Arctic Circle in Sweden. Larger pools were warmer than smaller ones, and clearing pools were warmer than forest pools. Temperature differences between pools remained high until late July. Twenty-one dytiscid species, representing three guilds, occurred in the pools, and individual pools had 1-13 species. Ten species occurred in both habitats. A few stenotopic species of boreal swamp forests had in clearing pools apparently been replaced by some species with a preference for more productive, often man-made habitats. Six Aedes species were collected in the clearing pools. Five of these were found in the forest pools, of which three had no mosquito larvae. Dytiscid assemblages in both habitats and culicid assemblages in clearing pools showed strong nested patterns. Abundance and species richness of both culicids and dytiscids were higher in clearing than in forest pools with an area <2 m 2 after that the effects of pool area had been accounted for (MANCOVA). In both habitats, abundanc
