Tabla de Contenidos:
- Introduction
- Which traits vary within plants? many different features vary across reiterated structures of the same plant
- Continuous within-plant variation of reiterated structures: the extent of subindividual variation in continuously varying leaf, flower, fruit, and seed traits is assessed
- Distribution of subindividual variability in time and space: how are variants of reiterated structures organized along temporal, spatial, and architectural axes?
- Causes of subindividual variability: mutations within individuals and organ-level responses to environmental cues are the main classes of remote causes of within-plant variability in reiterated structures
- 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
- Subindividual variability as an individual property: the Haldane-Roy conjecture is verified and extended: individual plants have not only their characteristic means, but also their characteristic standard deviations and characteristic spatial patterns of within-plant variation
- Consequences of within-plant variation for interacting animals: phytophagous animals' discrimination among organs of the same plant can lead to the most profitable choice but has attendant costs that may influence their overall performance and promote among-plant selectivity
- 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
- 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.
