Hypothesis
Can molecular methods detect predation of endangered species by invasive predators?
Conclusion
The study provides evidence of predation on the endangered Iberian desman and Mediterranean water shrew by the American mink.
Supporting Evidence
- Positive desman DNA was confirmed in two faecal samples.
- Predation on the Iberian desman was detected in the study area.
- American mink is identified as a significant threat to the desman population.
Takeaway
Scientists used special tests to find out if American minks are eating endangered animals like the Iberian desman and water shrews.
Methodology
The study used RT-PCR and DNA sequencing to analyze faecal and stomach content samples for predator and prey identification.
Limitations
The study relied on a small sample size and the need for further confirmation of results.
