The temporal and spatial dimensions of plant-soil feedbacks

Area of Science:

• Ecology
• Microbiology
• Soil Science

Background:

• Plant-soil feedbacks (PSFs) are fundamental to terrestrial ecosystems.
• Traditional views assumed well-mixed microbial communities and rapid microbial dynamics.
• Recent work highlights spatial and temporal mismatches in PSFs.

Purpose of the Study:

• To challenge assumptions about PSF dynamics.
• To emphasize the importance of spatiotemporal scales in PSFs.
• To propose a new research framework for PSFs.

Main Methods:

• Reviewing recent advances in understanding PSF spatial and temporal dynamics.
• Identifying limitations of current assumptions.
• Proposing a synthetic spatiotemporal framework.

Main Results:

• PSFs are not based on spatially uniform or rapid microbial dynamics.
• PSFs arise from interactions mismatched in space and time.
• Considering spatiotemporal dynamics is essential for ecological understanding.

Conclusions:

• A synthetic spatiotemporal framework is proposed for future PSF research.
• Integrating experimental and modeling approaches is key.
• This framework aims to enhance predictability and generalizability of PSFs.
