Description
| - Práce popisuje vliv chvostoskoků na aktivitu nematod a mikroorganismů a význam těchto interakcí pro mineralizaci C a N. (cs)
- We manipulated Collembola Folsomia candida Willem density and observed the density effect on carbon and nitrogen mineralization and on nematodes in microcosms filled with mineral soil. Collembolan densities were 0 (control), 25 (low), 100 (medium), and 400 (high) individuals per microcosm. The Collembola enhanced soil respiration and nitrogen mineralization rate in a density-dependent manner (p<0.05). The correlation between collembolan density and the metabolic quotient of microbes, qCO2, was weakly positive (r=0.44, p<0.05). Collembola did not affect microbial biomass. These results suggested that enhanced carbon and nitrogen mineralization was an indirect effect of Collembola mediated by increased microbial activity. Collembola changed the Cnema/Cmic ratio, but only when present at the low density. Thus, Collembola had both positive and negative effects on the nematode population.
