Report on the Ohio State University workshops in phylogenetic methods.

A three-part series of workshops in phylogenetic methods was held at the Ohio State University in September and December 2005. The first two were sponsored by the OSU Mathematical Biosciences Institute (MBI), and focused on phylogeography and phylogenetic data, and phylogenetic analysis of large data sets respectively. These workshops highlighted theoretical and practical aspects of phylogeographic inferences using model-based approaches (e.

Molecular systematic analysis reveals cryptic tertiary diversification of a widespread tropical rain forest tree.

The broad geographic range of many Neotropical rain forest tree species implies excellent dispersal abilities or range establishment that preceded the formation of current dispersal barriers. In order to initiate historical analyses of such widespread Neotropical trees, we sequenced the nuclear ribosomal spacer (ITS) region of Symphonia globulifera L. f.
