Hypothesis
Does phenotypic plasticity affect the process of invasion?
Conclusion
Phenotypic plasticity can act as a barrier to species invasions by altering the fitness landscape.
Supporting Evidence
- Phenotypic plasticity increases the steepness of the fitness surface, making invasion more difficult.
- Plastic species invaded habitats with non-plastic residents more quickly than vice versa.
- Invasion success is influenced by the evolutionary history of the resident and invader species.
Takeaway
Some animals can change how they behave based on their surroundings, which can make it harder for new animals to move in and take over their space.
Methodology
A computational model was developed to investigate the effects of phenotypic plasticity on species invasions in a tri-trophic food chain.
Limitations
The model may not capture all complexities of real-world ecosystems.
