          Abstract

          <p class="first" id="d7104142e163">Recent phylogenetic advances have uncovered remarkable biogeographic histories that have challenged traditional concepts of dispersal, vicariance and diversification in the Greater Antilles. Much of this focus has centred on vertebrate lineages despite the high diversity and endemism of terrestrial arthropods, which account for 2.5 times the generic endemism of all Antillean plants and non-marine vertebrates combined. In this study, we focus on three Antillean endemic praying mantis genera, <i>Callimantis</i>, <i>Epaphrodita</i> and <i>Gonatista</i>, to determine their phylogenetic placement and geographical origins. Each genus is enigmatic in their relation to other praying mantises due to their morphological affinities with both Neotropical and Old World groups. We recovered the three genera as a monophyletic lineage among Old World groups, which was supported by molecular and morphological evidence. With a divergence at approximately 107 Ma, the lineage originated during the break-up of Gondwana. Ancestral range reconstruction indicates the lineage dispersed from an African + Indomalayan range to the Greater Antilles, with a subsequent extinction in the Old World. The profound ecomorphic convergence with non-Caribbean groups obscured recognition of natural relationships within the same geographical distribution. To the best of our knowledge, the lineage is one of the oldest endemic animal groups in the Greater Antilles and their morphological diversity and restricted distribution mark them as a critical taxon to conserve. </p>

          SequenceMatrix: concatenation software for the fast assembly of multi-gene datasets with character set and codon information

          We present SequenceMatrix, software that is designed to facilitate the assembly and analysis of multi-gene datasets. Genes are concatenated by dragging and dropping FASTA, NEXUS, or TNT files with aligned sequences into the program window. A multi-gene dataset is concatenated and displayed in a spreadsheet; each sequence is represented by a cell that provides information on sequence length, number of indels, the number of ambiguous bases ("Ns"), and the availability of codon information. Alternatively, GenBank numbers for the sequences can be displayed and exported. Matrices with hundreds of genes and taxa can be concatenated within minutes and exported in TNT, NEXUS, or PHYLIP formats, preserving both character set and codon information for TNT and NEXUS files. SequenceMatrix also creates taxon sets listing taxa with a minimum number of characters or gene fragments, which helps assess preliminary datasets. Entire taxa, whole gene fragments, or individual sequences for a particular gene and species can be excluded from export. Data matrices can be re-split into their component genes and the gene fragments can be exported as individual gene files. SequenceMatrix also includes two tools that help to identify sequences that may have been compromised through laboratory contamination or data management error. One tool lists identical or near-identical sequences within genes, while the other compares the pairwise distance pattern of one gene against the pattern for all remaining genes combined. SequenceMatrix is Java-based and compatible with the Microsoft Windows, Apple MacOS X and Linux operating systems.

            RASP (Reconstruct Ancestral State in Phylogenies): a tool for historical biogeography.

            We announce the release of Reconstruct Ancestral State in Phylogenies (RASP), a user-friendly software package for inferring historical biogeography through reconstructing ancestral geographic distributions on phylogenetic trees. RASP utilizes the widely used Statistical-Dispersal Vicariance Analysis (S-DIVA), the Dispersal-Extinction-Cladogenesis (DEC) model (Lagrange), a Statistical DEC model (S-DEC) and BayArea. It provides a graphical user interface (GUI) to specify a phylogenetic tree or set of trees and geographic distribution constraints, draws pie charts on the nodes of a phylogenetic tree to indicate levels of uncertainty, and generates high-quality exportable graphical results. RASP can run on both Windows and Mac OS X platforms. All documentation and source code for RASP is freely available at http://mnh.scu.edu.cn/soft/blog/RASP.

              The conditioned reconstructed process.

              We investigate a neutral model for speciation and extinction, the constant rate birth-death process. The process is conditioned to have n extant species today, we look at the tree distribution of the reconstructed trees--i.e. the trees without the extinct species. Whereas the tree shape distribution is well-known and actually the same as under the pure birth process, no analytic results for the speciation times were known. We provide the distribution for the speciation times and calculate the expectations analytically. This characterizes the reconstructed trees completely. We will show how the results can be used to date phylogenies.
