Genetic polymorphism varies among species and within genomes, and has important
implications for the evolution and conservation of species. The determinants of this variation …

Hybridization has long been recognized as a fundamental evolutionary process in plants
but, until recently, our understanding of its phylogenetic distribution and biological …

A completely revised and rewritten edition of this comprehensive survey of the botanical
problems of pollination ecology approached from both a theoretical and a practical …

The influence of genetic variation on invasion success has captivated researchers since the
start of the field of invasion genetics 50 years ago. We review the history of work on this …

The Ecology of Natural Disturbance and Patch Dynamics brings together the findings and
ideas of researchers studying such varied systems as marine invertebrate communities; …

▪ Abstract Polyploidy is widely acknowledged as a major mechanism of adaptation and
speciation in plants. The stages in polyploid evolution include frequent fertility bottlenecks …

The transition from outcrossing to self-fertilization is one of the most common evolutionary
changes in plants, yet only about 10–15% of flowering plants are predominantly selfing. To …

Grasslands, in particular managed pastures and rangelands, are widespread, covering
approximately 40%(52 million km²) of the Earth's land surface. They are dominated by …

The overwhelming majority of biologists who have studied both the origin of races and
species and major trends of evolution in animals have reached the conclusion, in agreement …

The amounts of inbreeding depression upon selfing and of heterosis upon outcrossing
determine the strength of selection on the selfing rate in a population when this evolves …
