Nutrient enrichment and herbivore exclusion disrupt the climate-driven balance between C3 and C4 plants in grasslands

Joe Atkinson, Jodi Price, Robert Buitenwerf, Nicholas G. Smith, Ezinwanne Ezekannagha, Elizabeth T. Borer, Cynthia S. Brown, Lars Andrew Brudvig, Yvonne Maria Buckley, Miguel N. Bugalho, Maria C. Caldeira, Sofía Campana, Clinton Carbutt, Chris R. Dickman, Ian Donohue, , Jens‐Christian Svenning

The paper shows that nutrient enrichment, especially with nitrogen and phosphorus, reduces C4 plant cover in grasslands, disrupting climate-driven C3-C4 balance globally.

Local nutrient addition drives plant biodiversity losses but not biotic homogenization in global grasslands

Qingqing Chen, Shane A. Blowes, William Stanley Harpole, Emma R. Ladouceur, Elizabeth T. Borer, Andrew MacDougall, Jason P. Martina, Jonathan D. Bakker, Pedro M. Tognetti, Eric W. Seabloom, Pedro Daleo, Sally A. Power, Christiane Roscher, Peter B. Adler, Ian Donohue, , Jonathan M. Chase

This study shows nutrient addition reduces plant diversity at local and larger scales equally, without causing biotic homogenization in global grasslands.
