Outline of Final Research Achievements

The goal of this study is to explore the diet ages of consumers in three forest ecosystems with different climates. The estimation of diet age can be performed by using natural abundance of radiocarbon. The results showed that diet ages of soil invertebrates did not differ among the studies sites, despite great difference in soil properties, such as soil respiration and radiocarbon concentrations.
