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 …

Background In angiosperm evolution, autogamously selfing lineages have been derived
from outbreeding ancestors multiple times, and this transition is regarded as one of the most …

Understanding why some species have more genetic diversity than others is central to the
study of ecology and evolution, and carries potentially important implications for …

The shift from outcrossing to selfing is common in flowering plants,, but the genomic
consequences and the speed at which they emerge remain poorly understood. An excellent …

Geographic characters—traits describing the spatial distribution of a species—may both
affect and be affected by processes associated with lineage birth and death. This is …

Dated molecular phylogenies are the basis for understanding species diversity and for
linking changes in rates of diversification with historical events such as restructuring in …

Over the past 20 y, many studies have examined the history of the plant ecological and
molecular model, Arabidopsis thaliana, in Europe and North America. Although these …

Understanding the phenotypic and molecular mechanisms that contribute to genetic
diversity between and within species is fundamental in studying the evolution of species. In …

Mimulus guttatus and M. nasutus are an evolutionary and ecological model sister species
pair differentiated by ecology, mating system, and partial reproductive isolation. Despite …

Studies of plants have been instrumental for revealing how new species originate. For
several decades, botanical research has complemented and, in some cases, challenged …
