Organismal Mechanisms of Subindividual Variability: Ontogenetic contingency, the interplay between inherent architecture and environmental milieu, and developmental stochasticity are mechanisms responsible for within-plant variability of reiterated structures.

This chapter describes the organization of the response of the organism to its changing environment as well as the organization that it generates in and of itself. The author finds that the ... More


Evolutionary Implications of Within-Plant Variability in Organ Traits: Subindividual multiplicity of organs can affect the evolutionary trajectory of organ traits by setting upper limits on responses to selection, opening the possibility of selection by animals on plant-level variability, and conditioning the size of realized phenotypic space at the individual and population levels.

Fitness Consequences of Subindividual Variability in Organ Traits for Plants: Subindividual variation in the characteristics of reiterated organs may influence the fecundity or vegetative performance of plants, and through this mechanism, individual fitness differences may arise as a consequence of variation in the extent and organization of variability.
