| Description
| - Abundance and activities of the major bacterial groups in the two compartments of experimentally divided Lake Grosse Fuchskuhle (Germany) were examined. Water from the basins were incubated in dialysis bags, which allowed for a relatively free exchange of nutrients, limiting solutes and low molecular organic matter but fully prevented exchange of organisms. To investigate the effect of top-down and bottom-up manipulations three size fractions of water samples were produced: (i) unfiltered, (ii) pre-filtered through 5.0 µm pore size membranes to remove large particles, as well as grazers and (iii) pre-filtered through 0.8 µm filters to remove all potential bacterivores. One set of dialysis bags was either incubated in acidic SW (rich in humic matter) or in almost neutral NE basin whereas a second set was transferred from the SW to the NE basin and vice versa. Our study revealed pronounced differences in growth rates among the major bacterial groups in relation to the treatments.

- Abundance a aktivita hlavních skupin bakterií ve dvou částech experimentálně rozděleného jezera Grosse Fuchskuhle (Německo) byla zkoumána. Voda z obou částí byla inkubována v dialyzačních sáčcích, které umožňují relativně volnou výměnu nutrientů, limitujících rozpuštěných látek a nízkomolekulárních organických látek, ale kvantitativně zabraňují výměně organismů. Tři různé velikostní frakce byly připraveny : Nefiltrovaná voda, přefiltrovaná přes 5 µm a přefiltrovaná přes 0,8 µm filtr, za účelem manipulace predačního tlaku prvoků. Každý set dialyzačních sáčků byl inkubován v kyselém SW (bohatém na humické látky) kompártmentu jezera a zároveň v téměř neutrální NE části a naopak. Naše studie odhalila zajímavé rozdíly v růstových rychlostech u ruzných skupin bakterií v závislosti na nutrientech. (cs)
