Integration of plant-soil feedbacks with resilience theory for climate change

Area of Science:

• Ecology
• Environmental Science
• Climate Change Research

Background:

• Ecosystem resilience to climate disruption depends on internal feedbacks.
• Plant-soil feedback (PSF) is a key interaction potentially influencing ecosystem stability.
• The precise role of PSF in bolstering or diminishing ecosystem resilience remains unclear.

Purpose of the Study:

• To establish criteria for attributing ecosystem resilience to PSF.
• To investigate how PSF impacts ecosystem resistance and recovery under climate disruption.
• To explore the role of aboveground-belowground interactions in ecosystem resilience.

Main Methods:

• Defining three essential criteria to link PSF manipulation to observed resilience changes.
• Analyzing existing case studies for evidence meeting these criteria.
• Proposing future research designs to rigorously test PSF's impact on resilience.

Main Results:

• No previous study has fully met all criteria required to definitively link PSF to ecosystem resilience.
• Theoretical frameworks suggest PSF can either enhance or reduce ecosystem resilience.
• Case studies provide preliminary evidence but lack conclusive data.

Conclusions:

• Rigorous experimental approaches are needed to meet the established criteria for PSF and resilience.
• Understanding PSF is critical for predicting ecosystem responses to climate change.
• Further research on aboveground-belowground interactions will advance ecosystem resilience science.
