Pollinator parasites and the evolution of floral traits [PDF]
The main selective force driving floral evolution and diversity is plant–pollinator interactions. Pollinators use floral signals and indirect cues to assess flower reward, and the ensuing flower choice has major implications for plant fitness. While many

Evolution of Floral Fragrance Is Compromised by Herbivory [PDF]
Despite the paramount role of floral fragrance in pollinator attraction and reproduction in flowering plants, we know little about its evolution under natural conditions.

The ABCs of Floral Evolution [PDF]
Because eudicots and monocots are on separate deep branches of the angiosperm phylogenetic tree, the strong genetic and molecular evidence supporting the conservation of the ABC model suggests that this model represents an ancient regulatory network and is likely to be generally applicable to most, if not all, angiosperms.

The Evolution of Diverse Floral Morphologies [PDF]
The angiosperm flower develops through a modular programme which, although ancient and conserved, provides the flexibility that has allowed an almost infinite variety of floral forms to emerge. In this review, we explore the evolution of floral diversity, focusing on our recent understanding of the mechanistic basis of evolutionary change.

The evolution of imperfect floral mimicry [PDF]
The theory of mimicry predicts that selection favors signal refinement in mimics to optimally match the signals released by their specific model species. We provide here chemical and behavioral evidence that a sexually deceptive orchid benefits from its mimetic imperfection to its co-occurring and specific bee model by triggering a stronger response in

The evolution of floral guides: using a genetic algorithm to investigate the evolution of floral cue arrangements [PDF]
Many floral displays incorporate complex contrasting stimuli patterns in visual, olfactory and other sensory modalities. These ‘floral guides’ can increase pollen transfer rates and visitation rates for flowers while reducing the search times of pollinators.

Evolution of floral symmetry [PDF]
Abstract Flowers can be classified into two basic types according to their symmetry: regular flowers have more than one plane of symmetry and irregular flowers have only a single plane of symmetry. The irregular condition is thought to have evolved many times independently from the regular one: most commonly through the appearance of ...

The effect of experimental pollinator decline on pollinator‐mediated selection on floral traits
Human‐mediated environmental change, by reducing mean fitness, is hypothesized to strengthen selection on traits that mediate interactions among species.
