Hypothesis
With preceding succession, the characteristics of the carabid fauna change from those typical for open land to those typical for forest habitats.
Conclusion
The study found that the contribution of forest species and large zoophages increased significantly with the age of the forest stands, while the number of species and Mean Individual Biomass did not show significant changes.
Supporting Evidence
- The share of forest species increased significantly from below 50% in young stands to almost 90% in older stands.
- The share of large zoophages also increased significantly with the age of the stands.
- No significant correlation between Mean Individual Biomass values and the age of the stands was observed.
Takeaway
As forests get older, the types of beetles living there change from those that like open spaces to those that prefer forests.
Methodology
Carabid beetles were collected using pitfall traps across 24 plots in different forest age and moisture conditions over three years.
Limitations
The study may not fully account for all environmental factors influencing carabid assemblages.
