Hypothesis
Do generalist herbivores prefer native or exotic plants?
Conclusion
Generalist herbivores showed a strong preference for exotic plants over native ones.
Supporting Evidence
- Four of five herbivores showed a preference for exotic plants.
- Three species of South American apple snails preferred North American over South American plants.
- Generalist herbivores may provide biotic resistance to plant invasions.
Takeaway
Some animals that eat plants like to eat new plants that they haven't seen before, which are often from other places.
Methodology
The study tested feeding preferences of five generalist herbivores on nine pairs of native and exotic aquatic plants.
Potential Biases
Potential bias due to the limited number of herbivore and plant species tested.
Limitations
The study was conducted in a lab setting, which may not fully represent field conditions.
Participant Demographics
The study involved generalist herbivores from North and South America.
