Impact of Rabbit Disease on Partridge Predation
Author Information

Hypothesis
The RHD outbreak can potentially impact the dynamics of the red-legged partridge through hyperpredation.
Conclusion
The study provides evidence that a viral outbreak can lead to increased predation pressure on secondary prey species.
Supporting Evidence
- The RHD outbreak caused a significant decline in rabbit populations.
- Predators shifted their diet towards partridges after the rabbit population collapse.
- The study found synchronized population dynamics between rabbits and partridges.
Takeaway
When a disease makes rabbits sick and fewer in number, predators start eating more partridges instead, which can hurt the partridge population.
Methodology
The study analyzed long-term hunting bag records and population dynamics data of rabbits and partridges in Spain.
Potential Biases
Potential biases from hunting practices and the artificial release of partridges into the wild.
Limitations
The estimates of cross-species correlation may be conservative due to the artificial increase in partridge populations from captive breeding.
Participant Demographics
The study focused on the European rabbit and red-legged partridge populations in continental Spain.
