Despite the potential power and extensive use of DNA variation for phylogenetic
reconstruction, it has become increasingly apparent that DNA phylogenies are often …

Interpopulation gene flow in plants is mediated by a combination of pollen and seed
dispersal. The effectiveness of pollen and seeds in bringing about gene flow depends upon …

We developed stochastic population genetic theory for mitochondrial and chloroplast genes,
using an infinite alleles model appropriate for molecular genetic data. We considered the …

Although they are among the most abundant of all living things and provide essential
oxygen, food, and shelter to the animal kingdom, few books pay any attention to how and …

Various factors, including taxon density, sampling error, convergence, and heterogeneity of
evolutionary rates, can potentially lead to incongruence between phylogenetic trees based …

Three major tasks confront the molecular-evolutionary biologist. The first and most central of
these is to describe the natural history of a particular genome. This involves determining …

Systematists have long sought methodologies that would facilitate phylogenetic
reconstruction based on at most a few representative collections per species. As a result of …
