Abstract. Using an experimental approach, this study addresses the following two questions for the perennial herb Paeonia broteroi (Paeoniaceae) at a location in southeastern Spain. (1) What are the relative magnitudes of the effects of pollinators and herbivores (invertebrates and vertebrates feeding on flowers and developing fruits) on maternal fecundity (total seed production per plant)? (2) Are the effect...

Effects of pollinators, herbivores, and seed predators on flowering phenology.
Ecology ; INTRODUCTION Darwin's (1862) treatise On the various contrivances by which British and foreign orchids are fertilized by insects set the stage for the study of the evolution of floral design. Most work since has addressed the reciprocal effects of pollinators and their hosts. Research has focused
Floral characters link herbivores, pollinators, and plant fitness.
Ecology ; INTRODUCTION Both herbivores and pollinators have been shown to have large effects on plant fitness (e.g., references in Crawley 1983, Jones and Little 1983, Marquis 1992). Although much is known about the individual effects of herbivores and pollinators, relatively few studies have examined the

Whole Earth ; As I camp alone in a narrow canyon, waiting for a nocturnal pollinator to visit an endangered wildflower, I recite the names of threatened pollinators from around the world: Golden-manteled saddle-backed tamarins, moss-forest blossom bats, little wood-stars, turquoise-throated pufflegs, dibblers,
