TL;DR: Testing the hypothesis that herbaceous plant species losses caused by eutrophication may be offset by increased light availability due to herbivory demonstrates that nutrients and herbivores can serve as counteracting forces to control local plant diversity through light limitation, independent of site productivity, soil nitrogen, herbivore type and climate.

TL;DR: This article conducted a standardized sampling in 48 herbaceous-dominated plant communities on five continents and found no clear relationship between productivity and fine-scale (meters−2) richness within sites, within regions, or across the globe.
Life‐history constraints in grassland plant species: a growth‐defence trade‐off is the norm
Eric M. Lind,Elizabeth T. Borer,Eric W. Seabloom,Peter B. Adler,Jonathan D. Bakker,Dana M. Blumenthal,Michael J. Crawley,Kendi F. Davies,Jennifer Firn,Daniel S. Gruner,W. Stanley Harpole,Yann Hautier,Yann Hautier,Helmut Hillebrand,Johannes M. H. Knops,Brett A. Melbourne,Brent Mortensen,Anita C. Risch,Martin Schuetz,Carly J. Stevens,Peter D. Wragg +20 more
TL;DR: A growth-defence trade-off appears to be the norm within plant life-history groups and within the majority of individual sites, and mechanisms maintaining grassland biodiversity may operate within this constraint.

McCulley,Brett A. Melbourne,Charles E. Mitchell,Joslin L. Moore,John W. Morgan,Brent Mortensen,Lydia R. O'Halloran,David A. Pyke,Anita C. Risch,Mahesh Sankaran,Martin Schuetz,Anna K. Simonsen,Melinda D. Smith,Carly J. Stevens,Lauren L. Sullivan,Elizabeth M. Wolkovich,Peter D. Wragg,Justin P. Wright,Louie H. Yang +64 more
TL;DR: It is suggested that species origin has functional significance, and that eutrophication will lead to increased exotic dominance in grasslands.
