Journal ArticleDOI
Positive interactions in communities.
TL;DR: Evidence for the importance of positive interactions - facilitations - in community organization and dynamics has accrued to the point where it warrants formal inclusion into community ecology theory, as it has been in evolutionary biology.
Journal ArticleDOI
Competition and facilitation: a synthetic approach to interactions in plant communities
TL;DR: The roles of life stage, physiology, indirect interactions, and the physical environment on the balance of competition and facilitation in plant communities are discussed.
Journal ArticleDOI
Positive interactions among alpine plants increase with stress.

TL;DR: It is shown that the biomass, growth and reproduction of alpine plant species are higher when other plants are nearby, and that competition generally, but not exclusively, dominates interactions at lower elevations where conditions are less physically stressful.
Journal ArticleDOI
Positive interactions among plants
TL;DR: The evidence for facilitation, the mechanisms by which facilitation operates, and the effects facilitation has on community structure are reviewed.
Journal ArticleDOI
Facilitation in plant communities: the past, the present, and the future

TL;DR: There is substantial scope for exploring indirect facilitative effects in plant communities, including their impacts on diversity and evolution, and future studies should connect the degree of non-transitivity in plant competitive networks to community diversity and facilitative promotion of species coexistence.
