Hydrochemical and hydrological conditions of localities invaded by Bryozoans pectinatella magnifica (Leidy, 1851). A case study from BR Trebonsko, Czech repulic

Popis výsledku v původním jazyce

Preceeding in: SEFS 9 - Symposium for European Freshwater Sciences. Abstract book. Geneva, Switzerland. Pp. 181. During 2012 and 2013, 21 localities of invasive bryozoans Pectinatella magnifica ocurrence were found in Trebon region. These localities included waterbodies from eutrophic fishponds to oligotrophic sand-pits. Physical, hydrochemical and hydrobiological parameters werestudied. Control localities (with absence of P. magnifica) significantly differed from localities with P.m. in the most of parameters. P. magnifica forms colonies in large numbers on localities with above-average qualitative parameters: balanced oxygen and pH regime, low concentration of suspended solids (Secchi depth over 1m, turbidity to 9 NTU) and nitrogen forms (TN to 1.5 mg L-1), chlorophyll-a concentration to 36 ?g L-1, zooplankton density to 30 ind L-1 and biomass to 1 mg of wet weight L-1. P. magnifica was also found in brown humic waters. While sites with P. m. occurrence often include lakes under natu
