A meta-analysis on decomposition quantifies afterlife effects of plant diversity as a global change driver

A. S. Mori, J. H. C. Cornelissen, et al.

This global-scale meta-analysis reveals how plant litter diversity significantly enhances decomposition rates across various ecosystems, including forests, grasslands, and wetlands, a finding that parallels projected increases in decomposition due to climate change. This important research highlights the role of biodiversity changes in shaping future biogeochemical cycles and climate feedbacks, conducted by Akira S. Mori, J. Hans C. Cornelissen, Saori Fujii, Kei-ichi Okada, and Forest Isbell.

Abstract

This global-scale meta-analysis quantifies how plant litter diversity affects decomposition rates. The study finds significant and substantial positive effects of plant diversity on decomposition across forests, grasslands, and wetlands. The magnitude of this effect is comparable to projected increases in decomposition rates due to climate change over the next 50 years. This highlights the importance of considering biodiversity changes as a significant driver of future biogeochemical cycles and climate feedbacks.
