Facilitation and plant phenotypic evolution

While antagonistic interactions between plants have been a major topic of eco-evolutionary research, little evidence exists on the evolution positive plant (i.e., facilitation). Here, we first summarize existing empirical role facilitation as selection pressure plants. Then, develop theoretical framework based fitness-trait functions and interaction effectiveness that provides predictions for how facilitation-related traits may evolve. As act at levels beyond individual (such groups or species), discuss subject units evolutionary through facilitation. Finally, use proposed formal to identify areas future research knowledge gaps detected.
