Using genetic data to resolve the evolutionary relationships of species is of major interest in evolutionary and systematic biology. However, reconstructing the sequence of speciation events, the so c
Individuals of Pediomelum tenuiflorum, “wild alfalfa”, from disjunct populations in Nebraska vary extensively in their overall gestalt. Those in the western and central part of the state have a very s
Species tree methods are now widely used to infer the relationships among species from multi-locus datasets. Many methods have been developed, which differ in whether gene and species trees are estima
