About the Journal
The Bulletin of the Society of Systematic Biologists will publish manuscripts that advance our understanding of the Earth's biodiversity, with a special focus on investigations that describe how species are related (i.e., phylogeny), identified (i.e., species delimitation or taxonomic practice) or have evolved (e.g., phylogeography, biogeography, or phylogenetic comparative methods). BSSB will also publish manuscripts that advance the theory or methods used in data analysis. Manuscripts will be evaluated on two criteria: the quality of the science and their contribution to our collective understanding of the focal species or clade. BSSB aims to publish investigations that utilize state of the art data analyses and high-quality data sets to achieve these goals.
