Sažetak
Colonization of aquatic insect larvae was investigated in a second order woodland stream using trays filled with natural substrate. Patterns of colonization differed significantly between seasons in terms of number of taxa, density and biomass of aquatic insects assemblages. Larvae of first (out of five) size class made up 35, 5 % of all colonizers during the spring, highest share of 54, 1 % during the summer, 40, 8% and 17, 5% during the autumn and winter. Many peak values in density during spring and summer matched with single-species mass colonization of first or second size classes, explained by “distributional drift” of newly-hatched insects, or direct oviposition on a substrate. Size structure of the whole community did not change with time of exposition ; however it reflected life history features of aquatic insects, which led to seasonal changes in colonization patterns.
