The influence of mesoscale habitat conditions on the macroinvertebrate composition of springs in a geologically homogeneous area

Popis výsledku v původním jazyce

We analyzed the composition of spring fauna in relation to the mesoscale variability in environmental conditions in 77 permanent springs. We hypothesized that the species would occur in definite patterns reflecting the differences in factors that operateat the spring-level scale. We used binomial regression to construct single-species environmental models for several of the most abundant taxa. The most important factors explaining the species? occurrence were hydromorphological and substrate characteristics. Results of NMDS ordination on species composition indicated 3 groups of springs. Group 1 separated springs with running water, high substrate heterogeneity, and high taxonomic richness. Groups 2 and 3 included mostly helocrene-like springs differing in slope and substrate composition. The springs from group 3 had lower species abundances. Our study demonstrates the importance of mesoscale differences in habitat conditions for structuring the springassociated benthic assemblages.
