dcterms:description
V oligo-mesotrofním jezeře Piburger (Rakousko) jsme studovali vliv žraní prvoků a dostupnost fosforu na početnost a biomasu bakterií z různých fylogenetických skupin. Zvýšení predační tlak způsobil pokles počtů bakterií s vysokým obsahem nukleových kyselin a vedl k nižší detekci bakterií pomocí fluorescenční in situ hybridizace. Predace ovlivnila zejména skupinu Betaproteobacteria, méně pak již skupiny Alphaproteobacteria a Cytophaga-Flavobacterium-Bacteroides. Betaproteobacteria byla dominantní skupinou za zvýšené dostupnosti fosforu a účinně kompetovala o fosfor. Přídavek živin naproti tomu nevyvolal růstovou odezvu u skupiny Actinobacteria, která navíc díky velmi malé velikosti představovala pouze nepatrnou část celkové biomasy bakterií. Během pokusu došlo ke zvýšení podílu bakterií s vysokým obsahem nukleových kyselin, což poukazuje na celkově vyšší aktivitu bakteriálního společenstva. We studied the impact of protistan grazing and phosphorus availability on the numbers and biomasses of bacteria from various phylogenetic lineages, and on their growth and activity parameters in the oligo-mesotrophic Piburger See, Austria. Enhanced grazing resulted in decreased proportions of bacteria with high nucleic acid content (HNA bacteria) and lower detection rates by FISH. Betaproteobacteria were heavily grazed while Alphaproteobacteria and Cytophaga-Flavobacterium-Bacteroides were less affected by predators. In the treatments enriched with phosphorus, Betaproteobacteria became dominant and successful opportunistic competitors for nutrients. In contrast, Actinobacteria did not respond to surplus phosphorus by population growth, and maintained their small size, which resulted in a very low biomass contribution. In addition, significant relationships between HNA bacteria and several bacterial phylogenetic clades were found, indicating an enhanced activity status.
