Résumé

Using data from 8 published competition experiments with diallel designs, and a new method of analyzing such data, presents evidence that competition among herbaceous plants has 2 general properties: pairwise interactions are predominantly asymmetric, and competitive hierarchies exist, ie competitive networks are primarily transitive. This empirical evidence is compared with what is known about the mechanisms of plant competition. A hypothesis explains some of the variability in the degree to which competitive networks display asymmetry and transitivity, and explores some of the consequences of this in terms of developing a predictive theory of plant competition. -from Authors
