The integration of phylogenetic, ecological and population-genetic studies have provided new insights into the selective mechanisms that are responsible for major evolutionary transitions between reproductive modes. Expand
A comparative analysis of pollen limitation in flowering plants
The results suggest that the influence of phylogenetic history on the intensity of pollen limitation was not particularly strong, and significant variation in the degree of pollen limitations was demonstrated among seven angiosperm families suggesting some phylogenetic component to the phenomenon. Expand
Wind of change: new insights on the ecology and evolution of pollination and mating in wind-pollinated plants.
These findings challenge the explanation that the evolution of few ovules in wind-pollinated flowers is associated with low pollen loads and it is proposed that geitonogamous selfing may alleviate pollen limitation in many wind- pollinated plants with unisexual flowers. Expand
The Reproductive Biology and Genetics of Island Plants
Stochastic forces play a major role in governing patterns of genetic variation in island populations and appear to be a factor involved in the evolution of sexual dimorphisms. Expand
The Ecological and Evolutionary Consequences of Clonality for Plant Mating
Evidence for the correlated evolution of clonality and sexual systems, particularly self-incompatibility, is reviewed, and several floral mechanisms that function to reduce mating costs by limiting selfing and pollen discounting are identified. Expand
Plant reproductive systems and evolution during biological invasion
Evidence is provided that evolutionary modifications to reproductive systems promote the colonizing ability of invading populations and that reproductive timing is an important target of selection during range expansion. Expand
Common garden comparisons of native and introduced plant populations: latitudinal clines can obscure evolutionary inferences
The results indicate that unrecognized geographic clines in phenotypic traits can confound inferences about the causes of evolutionary change in invasive plants. Expand
Heterostylous Genetic Polymorphisms: Model Systems for Evolutionary Analysis
Heterostyly is reported from approximately 25 angiosperm families and has usually been viewed as a floral device that promotes outcrossing, hence reducing the harmful effects of close inbreeding in plant populations. Expand
The comparative biology of pollination and mating in flowering plants
This work addresses three topics in reproductive biology: floral allocation strategies, mating systems and life history, and the origin of complex reproductive syndromes using various comparative methods. Expand
Rapid Adaptation to Climate Facilitates Range Expansion of an Invasive Plant
Examination of local adaptation along a climatic gradient in the North American invasive plant Lythrum salicaria shows that the evolution of earlier flowering is adaptive at the northern invasion front, demonstrating that local adaptation can evolve quickly during range expansion, overcoming environmental constraints on propagule production.
