Nitrogen addition and drought impose divergent effects on belowground bud banks of grassland community: a meta-analysis.

ABSTRACT:

Introduction

Belowground bud banks (or bud-bearing organs) underlie grassland regeneration and community succession following ecosystem perturbations. Disturbances of nitrogen (N) enrichment, overgrazing, wildfire, and drought substantially affect grassland ecosystem succession and aboveground productivity.

Methods

To understand the magnitude and direction of the disturbances on the belowground bud banks, we conducted a meta-analysis on 46 peer-reviewed studies published from 1980 to 2023. The meta-analysis comprises 231 observations of bud bank density per unit area and 410 observations of bud bank density per tiller.

Results

Results indicate that N addition remarkably promotes bud banks densities and plant functional groups of grass in the belowground bud banks. Whi
