"This paper presents a part of the results from studies of springs. The abiotic conditions and fauna composition of 68 oligotrophic springs in the Blanice river catchment were investigated with a focus on their relationship to the Pisidium species occurrence. We attempted to determine the habitat requirements of individual pea clam species. Species of genus Pisidium generally preferred unshaded springs with fine substrate, the most favourable were the helocrene springs. Although they were the second most numerous taxonomical group in the springs, only two species were represented there: Pisidium casertanum and Pisidium personatum. The occurrence of both species strongly positively correlated with each other. While Pisidium casertanum was found to be the most abundant in vegetation, Pisidium personatum preferred humolite substrate. The occurrence of Pisidium casertanum was further influenced by nutrients compared to Pisidium personatum, whose occurrence positively correlated with the common minerals."@en . .
