Abstract

ORIG CZ

V originále

The distribution patterns of 18 Sphagnum species along base-richness and altitudinal gradients were studied in Bulgarian treeless wetlands. Of 483 spring and mire sites studied, 202 samples contained some Sphagnum species. The significance of Sphagnum responses to environmental gradients was tested by comparing generalized additive models against the null model. Many Sphagnum species displayed a significant response to the altitudinal gradient. Several species were clearly linked to low or to high altitudes, but the realized niche of other species was wide with respect to altitude. Most species significantly responded to water pH, both above and below the timberline. Only a few species had a significant response to conductivity above the timberline.

In Czech

Zkoumali jsme rozšíření rašeliníků podél ekologických gradientů v Bulharsku, zjistili vazbu jednotlivých druhů na nadmořskou výšku a pH a popsali spefické ekologické chování některých mistních populací.
