Diversity of Belowground Carabid Beetles in the Western Palaearctic
Author Information

Primary Institution: Leuphana University Lüneburg
Hypothesis
There are weak links between belowground diversity and current climatic conditions, with a strong signal of history in the distribution patterns of belowground carabids.
Conclusion
The study found that species richness of belowground carabids is strongly influenced by historical processes and elevation range rather than current climate.
Supporting Evidence
- Species richness of belowground carabids showed a clear latitudinal gradient, highest in southern Europe.
- Richness was most strongly related to range in elevation.
- Current climate variables explained less variation in species richness than historical factors.
Takeaway
This study looked at beetles that live underground and found that where they live is more about history and how high the land is than the current weather.
Methodology
The study analyzed country-level species and environmental data using regression modeling and variation partitioning.
Limitations
The study excluded Iceland and small countries, which may limit the generalizability of the findings.
