Do autumn leaf colors serve as a reproductive insurance against sucking herbivores?
Article Abstract:
The coevolution hypothesis of autumn leaves is modified to suggest that much of the within-population variation in autumn leaf colors can be explained in the allocation of resources to sexual reproduction. While earlier hypotheses on the reasons for autumn color changes of deciduous woody plants consider physiological necessities and the effect of herbivory on plant growth, the reproductive insurance hypothesis focuses on plant's need to optimize their reproduction.

Dissecting components of population-level variation in seed production and the evolution of mating behavior
Article Abstract:
The interrelationships of components from species exhibiting strong masting to others with little annual variability in seed production are examined. The potential for fine-tuned selection on seed production patterns are described.
