New paper - synthetic evidence showing that intraspecific competition is stronger than interspecific competition in plant communities

By andrew, June 25, 2018

Our new paper – a collaborative effort of several USU Wildland Resources and Ecology Center researchers, led by Peter Adler – shows that the preponderance of evidence from published studies suggests that intraspecific competition is greater than interspecific competition in terrestrial plant communities. This is a key ingredient for stable coexistence, but empirical evidence for this theoretical necessity was previously found to be weak. Our analysis resolves a longstanding mismatch between theory and data, and shows that mechanisms that promote coexistence at local scales are common.
