Competitive Ability and Species Coexistence: A 'Plant's-Eye' View

This paper develops a «plant's-eye» view of avoiding competitive exclusion which interprets coexistence at the species level as a consequence of ongoing selection resulting from genetically-based differences in competitive abilities within local neighborhoods. That competitive ability may change as a consequence of selection is supported by results from a multi-generation competition experiment involving Senecio vulgaris and Phleum pratense
