Plant functional traits often vary across space, particularly when species encounter contrasting environmental conditions throughout their range. Such phenotypic variation is determined by both genetic and environmental...
In speciation, the formation of new lineages can be driven by two basic evolutionary processes—lineage divergence and lineage fusion. Lineage divergence can happen through differential adaptation or genetic drift, with...
Speciation is often described as a continuum, from minor divergence of populations to complete reproductive isolation between species. Within-species population divergence can shed light on the first steps of speciation...
