What are ecosystem feedbacks?
Ecosystem feedbacks are cause-and-effect loops where a change in one part of an ecosystem creates responses that either amplify the change or help restore balance.
What is a positive feedback loop in ecology?
A positive feedback loop reinforces the original change. For example, drought can reduce vegetation, which can increase heat and water loss, making drought stress worse.
What is a negative feedback loop in ecology?
A negative feedback loop helps stabilize a system. Forest regrowth, soil recovery, water retention, and biodiversity can all reduce disturbance and support ecosystem resilience.
Why are ecosystem feedbacks important?
They help explain how forests, soils, microbes, water, climate, and biodiversity respond to change. Feedbacks determine whether ecosystems move toward resilience, recovery, instability, or collapse.
How do mycelial networks relate to ecosystem feedbacks?
Mycelial networks are fungal systems that connect roots, microbes, water, nutrients, and carbon. They are one of the clearest examples of living feedback networks beneath the soil.
Can humans improve ecosystem feedbacks?
Yes. Regenerative agriculture, soil restoration, wetland protection, reforestation, biodiversity support, and reduced disturbance can strengthen stabilizing feedback loops.
