| Description
| - Uspořádali jsme manipulační pokus k objasnění vlivu různé míry dostupnosti živin, zejména fosforu, predace prvoků a vlivu virů na složení společenstva bakterioplanktonu v meso-eutrofní nádrži. Vzorek odebrabý z přítokové části nádrže bohaté na živiny byl filtrací rozdělen do velikostních frakcí a poté inkubován v dialyzačních sáčcích v přítoku a u hráze nádrže. Složení bakteriálního společenstva bylo sledováno pomocí fluorescenční in situ hybridizace s využitím oligonukleotidových sond. Přenos vzorků k hrázi nádrže chudé na živiny vyvolal pouze velmi málo významných změn ve složení společenstva bakterií. Byly pozorovány významné změny v morfologii a biomase bakterií. U některých skupin bakterií vedla zvýšená predace prvoků ke vzniku vláken, vloček a vibrio morfotypů. Dopad virů na společenstvo bakterií byl v porovnání s prvoky zanedbatelný. (cs)
- We conducted a transplant experiment to elucidate the effects of different levels of grazing pressure, nutrient availability, especially phosphorus, and the impact of viruses on the changes in the structure of bacterioplankton assemblage in a meso-eutrophic reservoir. A sample taken from the nutrient-rich inflow part of the reservoir was size-fractionated and incubated in dialysis bags in both inflow and dam area. The structure of bacterial assemblage was examined by fluorescence in situ hybridization using oligonucleotide probes with different levels of specificity. We found very few significant changes in the bacterioplankton composition after transplanting the treatments to the nutrient-poor dam area. We observed marked shifts in morphology and biomass towards the development of filaments, flocs and “vibrio-like morphotypes induced by increased grazing pressure. Impact of viruses on bacterioplankton was rather negligible.
