Complete genome sequences from a genus of Gammaproteobacteria, Shewanella, are used to generate a genome-wide exploration of the gene-tree species-tree dichotomy. A number of datasets were constructed
The conceptualization and coding of characters is a difficult issue in phylogenetic systematics, no matter which inference method is used when reconstructing phylogenetic trees or if the characters ar
The hemipteroid insect orders (Hemiptera, Psocodea, and Thysanoptera) are a diverse group among the insects, including over 120,000 described species. This group contains many species of ecological,
Enormous effort has been put into assembling the tree of life. This progress toward a complete phylogeny of living things has been accomplished through analysis of molecular data. Some lineages are po
