摘要：Numerous ecological services provided by a system tend to change over time, thus, making it tougher for policy makers/managers to evaluate trade-offs while estimating the cost-benefit analysis. Learning the resilience, threshold level and lag times allows us to gauge the strength and weakness of our technological advances and policies that might help us to cope with nonlinear impacts of global climatic change in ecosystems such as freshwater wetlands. Aquatic ecosystems can be very sensitive to changes induced by global climate change, e.g., water quality and quantity, and temperature. Thus, any mitigating strategies should try to take into account the nonlinear behaviors of the ecosystem processes and components, and begin planning to minimize effects of the changes.
