▪ Abstract Many uses of gene trees implicitly assume that nominal species are monophyletic
in their alleles at the study locus. However, in well-sampled gene trees, certain alleles in one …

▪ Abstract The number, size, and scope of phylogenetic analyses using molecular data has
increased steadily in recent years. This has simultaneously led to a dramatic improvement in …

Modern attempts to produce biogeographic maps focus on the distribution of species, and
the maps are typically drawn without phylogenetic considerations. Here, we generate a …
