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.

This chapter elaborates myriad mechanisms in subindividual variability in organ traits that might in the long run have some nontrivial evolutionary consequences for the plants. It is seen that the fitness effects of within-plant variation in organ traits are not much better established to date for discrete than for continuous variation. It is shown that “division of labor” exploitation of environmental patchiness or partitioning of environmental gradients need not be restricted either to discontinuous variation or to the partitioning of the physical, abiotic environment. The biotic environment represented by pollinators or seed dispersers is also susceptible to partitioning, or “division of labor,” by structures borne on the same plant performing the same function but differing slightly in their phenotypic characteristics.

Keywords:   subindividual variability, within-plant variation, division of labor, phenotypic characteristics, discontinuous variation, organ traits
