| Popis | Dactylogyrid species communities were studied in roach, Rutilus rutilus, collected from two localities in the basin of Morava River. Dactylogyrid species were found to co-occur on the gills of roach with up to six species found on the same host individual. Nine dactylogyrid species were identified with abundance of each reaching a very low level. Niche size was considered to increase with species abundance even when water temperature was high. There was strong effect of water temperature on abundance of the commpon dactylogyrid species as well as of the rare species. The temporary occurence of the rare species was found without any temperature effect. Water temperature did not affect the relationship between abundance and niche size. Niche size increased with abundancem even when the water temperature was high, which suggests that negative interpecific interactions aer not important within dactylogyrid communities. |
