Author Information

Primary Institution: Department of Biology, University of Bergen
Hypothesis
We hypothesize that Xyleborus pfeilii, which has always been treated as indigenous, is an alien species from Asia.
Conclusion
The study identifies 19 alien bark beetle species established in Europe, with significant implications for forest ecosystems.
Supporting Evidence
- There are 19 alien species established in continental Europe.
- Seventeen species are naturalized.
- Eleven species are native to Asia, six to the Americas, and one is from the Canary Islands.
- The Mediterranean is especially favorable for invasives, hosting a large proportion of the aliens.
- Low numbers for some countries are likely due to under-reporting.
Takeaway
This study looks at bark beetles that are not originally from Europe but have moved there and are causing problems for forests.
Methodology
The study is a review based on primary literature and databases of invasive species in Europe.
Potential Biases
The reliance on databases that may contain errors introduces risks of bias in the reported species.
Limitations
The study acknowledges that many records of alien species are incomplete or misleading due to under-reporting.
