Abstract

The seasonal dynamics of Bythonomus lemani (Lumbriculidae) were studied for the first time and the knowledge of Bothrioneurum vejdovskyanum (Tubificidae) was extended in the Rokytná River (Czech Republic) during April 1999 – April 2001. The influence of water temperature, velocity, depth, discharge, pH, conductivity, dissolved oxygen amount and biochemical oxygen demand (BOD) on their life cycles was evaluated. Habitat preferences of the juvenile and adult stages were recorded. Time series analysis was used to determine the worm densities, seasonality and trends. For Byth. lemani one distinct reproduction cycle per year was found and this was regulated by temperature, while Both. vejdovskyanum showed a one-year cycle not significantly dependent on measured environmental variables. Byth. lemani showed a significant negative correlation between the trend of its density and BOD concentration.

Abstract (in Czech)

Sezónní dynamika druhu Bythonomus lemani (Lumbriculidae) byla vyhodnocena poprvé a dále byly rozšířeny znalosti o rozmnožování Bothrioneurum vejdovskyanum (Tubificidae) v řece Rokytné (ČR) během období duben 1999 - duben 2001. Byl vyhodnocen vliv teploty vody, rychlosti proudění, hloubky, průtoku, pH, vodivosti, koncentrace rozpuštěného kyslíku a BOD na jejich životní cykly. Byly sledovány habitatové preference juvenilních a adultních stádií. Pro vyhodnocení denzity červů, sezonality a trendů byla použita analýza časových řad. U Byth. lemani byl nalezen jednoletý cyklus regulovaný změnami teploty, zatímco Both. vejdovskyanum měl také jednoletý cyklus, ale bez vztahu ke sledovaným proměnným prostředí. Byth. lemani prokázal negativní korelaci mezi denzitou a BOD koncentrací.
