    The relative role of interference competition in regulation of a rotifer community during spring development in a eutrophic reservoir

  • Original language description

    The relative importance of interference and exploitative competition from Daphnia was tested in contrast to known role of Cyclops vicinus predation, influencing the rotifer community in Římov Reservoir during spring period. The abundances of five dominant rotifer species and their birth and death rates were analysed, together with changes in chl-a concentration, HNF, bacteria biomass and the abundances of predator and competitor species, from high frequency sampling. Development of loricated species (Keratella cochlearis, K. quadrata, Kellicottia longispina) was driven predominantly by food availability. The dominant soft-bodied species Polyarthra spp. and Synchaeta lakowitziana were affected predominantly through C. vicinus predation. The role of mechanical interference from D. galeata, although may be important in a limited periods was overclouded by predation and exploitative competition in general.

    Relativní význam interferenční kompetice v regulaci společenstva vířníků během jarního maxima v eutrofní nádrži

  • Czech description

    Relativní význam interferenční a exploatativní kompetice Daphnia byl testován v porovnání s predaci Cyclops vicinus v Římovské nádrži. Byla sledována natalita, mortalita a změny abundancí pěti hlavních druhů vířníků v závislosti na potravně predačních akompetičních charakteristikách nádrže. Rozvoj lorikátních druhů vířníků (Keratella cochlearis, K. quadrata, Kellicottia longispina) byl řízen především dostatkem vhodné potravy, zatímco vířníci s měkkým tělem (Polyarthra spp., Synchaeta) predací C. vicinus. Význam mechanické interference s D. galeata byl minoritní.
