Abstract
This study deals with the habitat preferences of medicinal leech Hirudo medicinalis Linnaeus, 1758 in the Czech Republic. Division of localities based on aquatic vegetation (TWINSPAN) formed groups of localities which corresponded to the population sizes of H. medicinalis. According to the abiotic factors localities with H. medicinalis were rich in carbon, poor in oxygen and situated in an area with warm climate. In this study four different ventral color patterns were described. During the ontogenetic development ventral side becomes darker, as indicated by the significant relationship between the percentage of dark color and leech size.
Abstract (in Czech)
Studie se zabývá habitatovými preferencemi pijavky lékařdké Hirudo medicinalis Linnaeus, 1758 v České republice. Rozdělní lokalit založené na vodní vegetaci (TWINSPAN)vytvořilo skupiny odpovídající velikosti populací pijavky lékařeké. Podle abiotických faktorů byly lokality s pijavkou bohaté na uhlík, chudé na kyslík a ležely v malých nadmořských výškách. V této studii byly popsány 4 vzory břišního zbarvení. Během ontogenze břišní strana tmavne.
