Description Trichodrilus strandi Hrabě, 1936, likewise other congeners, belongs to the stygophilous species. There was little known about this species in the Czech Republic and Slovakia, but recent field research of treeless spring fens (with various geographical position, size, altitude, vegetation, mineral richness of water, substrate etc.) in the Western Carpathians showed that Trichodrilus strandi prefers mineral-rich fens with tufa formation and its populations reach high abundances replacing other oligochaete species there. Later research of nearby brooks revealed that this species inhabited also adjacent brooks but only in waters with alkaline reaction. The aim of our study was to compare populations of Trichodrilus strandi living in spring fens and in nearby brooks. Material was collected in spring and autumn seasons (2006–2013), in spring fens at two mesohabitats (standing water and flowing water), in brooks at three mesohabitats (riffle, pool, mosses). Main factors determining the presence of Trichodrilus strandi were identified. Some differences between these two main types of habitat and also between individual mesohabitats were observed.
