Abstract
The relationships between physico-chemical parameters and the taxonomic and functional structure of benthic macroinvertebrate communities were investigated in streams and rivers of the Hindu Kush-Himalayan region. 190 stream and river reaches distributed along the gradient of eutrophication and water pollution, and located in a wide range of altitude were sampled in two different seasons. Many environmental parameters including the catchments geology, land use, channel morphology and water chemistry were recorded. Family-level identifications of macroinvertebrates were used in statistical analyses. Multivariate statistical methods were used to analyze the large data set. Although the results indicate strong relationship between the macroinvertebrate taxonomic structure and the altitude of the sampling sites, the largest variance in the biological data could be found on the functional-feeding gradient. The differences in the functional structure of the macroinvertebrate communities could be explained by some chemical parameters and eutrophication.
Abstract (in Czech)
Vztah mezi fyzikálně-chemickými parametry and taxonomickou a funkční strukturou bentických bezobratlých byl analyzován na tocích Hindu Kush-Himalájského regionu. Celkem 190 úseků toků bylo analyzováno. Zaznamenány byly proměnné charakterizující geologii, využití krajiny, morfologii koryta a vodní chemii. Ačkoliv výsledky vicerozměrných metod indikují silný vztah mezi biotou a nadmořskou výškou, směr hlavní variability byl nalazen ve funkčně-potravním gradientu. Odlišnosti ve funkčně-potravní struktuře společenstev je vysvětlován chemickými parametry a eutrofizací.
