Hypothesis
How do habitat-mediated facilitation and counteracting ecosystem engineering influence ecosystem responses to disturbance?
Conclusion
The study found that interactions between seagrass and lugworms can significantly affect the recovery of ecosystems after disturbances.
Supporting Evidence
- Seagrass recolonization was unaffected by lugworm addition.
- Lugworm densities increased in larger clearings.
- The risk of disturbance to seagrass increased with hollow size.
Takeaway
This study shows that when seagrass is disturbed, lugworms can make it harder for the seagrass to come back, especially if the disturbance is big.
Methodology
The study used field surveys and removal-addition experiments to assess the effects of seagrass and lugworm interactions on ecosystem recovery.
Potential Biases
Potential biases may arise from the specific environmental conditions of the study site.
Limitations
The study did not identify the specific additional disturbances affecting seagrass recovery.
