Contribution of ant and microbial respiration to CO2 emission from wood ant (Formica polyctena) nests

Popis výsledku v původním jazyce

As ecosystem engineers, wood ants (Formica s. str.) influence many processes in forest ecosystems. Their nests are "hot spots" for CO2 production, and some nests are relatively wet (>35% moisture content) while others are dry (<20% moisture content). Inthis study, we compared CO2 production, the contribution of ant and nest material respiration to the overall CO2 production, and the rate of decomposition in dry vs. wet nests of wood ants (Formica polyctena). We also determined whether ants increase microbial respiration in nest material. Respiration in ant nests was higher than in the surrounding soil and was higher in wet nests than in dry nests. Ant contribution to the overall respiration was significantly higher than that of nest material respiration: the average ratio of the contributions (ants:nest material) was 75:25%. Litter mass loss (determined with litter bags buried in the nests) was significantly higher in wet nests than in dry nests. In a laboratory experiment, respiratio
