Does sociality affect the evolution of chromosome number? Such a collective effort is needed to fill in details about sexual systems across the Tree of Life. Tree structure is derived from taxonomy, where each tip represents all species in a single genus. For plants, the database includes genera with data on sexual systems , although we concentrated our data collection on 77 clades primarily genera , which were known to be variable for sexual system. Full size image Figure 2: Examples of the type of questions that are being addressed using the database are: Diploid chromosome number is indicated by the height of the innermost ring; all other rings indicate the presence or absence of the trait named at the base of the ring. Vertebrate traits Data for fish, non-avian reptiles, amphibians, mammals, and birds were compiled from literature searches. For many species, data were obtained from the initial taxonomic description of the species or from subsequent primary literature about the species. Do hermaphrodites diversify more rapidly than species with separate sexes dioecy? What factors influence loss of Y chromosomes? The database will also facilitate rapid identification of suitable taxonomic groups that contain variation in traits of interest for future studies of sexual systems and sex determination. Distribution and sample of plant data from the Tree of Sex Database. By synthesizing existing data on sexual systems, the database will allow biologists to identify the evolutionary and ecological processes that underlie the remarkable diversity in sexual systems across the tree of eukaryotic life. The sexual trait data displayed in the rings is based on 11, invertebrate entries. Distribution and sample of invertebrate data from the Tree of Sex Database. For these 77 clades, the database has high coverage of the available information, enabling users to address questions about the impact of sexual system on evolutionary and ecological processes. Furthermore, some data are not available in English or require expert interpretation, reducing the usability of the data.

The database will also facilitate rapid identification of suitable taxonomic groups that contain variation in traits of interest for future studies of sexual systems and sex determination. Information in the database, coupled with phylogenetic information, is being used to determine the impact of dioecy on speciation and extinction rates across multiple genera of plants. For each species and trait, state values and data sources were entered in the database. By synthesizing existing data on sexual systems, the database will allow biologists to identify the evolutionary and ecological processes that underlie the remarkable diversity in sexual systems across the tree of eukaryotic life. By mapping changes in sexual systems to the tree of life, we are assessing whether some transitions are more likely to happen than others e. Does sociality affect the evolution of chromosome number? While the database is not complete, it provides a framework within which additional data can be added by the community. Distribution and sample of invertebrate data from the Tree of Sex Database. Tree structure is derived from taxonomy, where each tip represents all species in a single genus. Eusocial lifestyles may create selection pressure for increased recombination and indirectly increase the number of chromosomes; we are performing a comparative analysis to test this hypothesis.

Does environmental sex determination place species at heightened risk of extinction, especially in the face of a changing climate? The sexual trait data displayed in the rings is based on 2, vertebrate entries. Full size table To build the database, we surveyed the literature, on-line databases, and expert scientists to obtain species-level descriptions of the traits listed in Tables 1 and 2. Full size image Figure 3: The sexual trait data displayed in the rings is based on 11, invertebrate entries. Remaining features as in Figure 1. Such a collective effort is needed to fill in details about sexual systems across the Tree of Life. We avoided using generic information about higher-level taxa e. What factors influence loss of Y chromosomes? The data are being used to assess which taxa are most likely to undergo fusions between autosomes and sex chromosomes to test ideas about the drivers of fusion events. For some taxa Coleoptera, Hymenoptera, Diptera, Acari , we have endeavored to make our database comprehensive, representing nearly all known data about the sexual traits compiled. Complex SCS indicates species with complex sex chromosome karyotypes e. Full size image The Tree of Sex database facilitates comparative analyses exploring hypotheses about the evolutionary factors driving transitions among sexual systems.

Are some sexual systems more transient than others? For each species and trait, state values and data sources were entered in the database. While these data are readily available in hard copy in many libraries, it is prohibitively time consuming to track down information species-by-species for use in analyses across broad taxonomic scales. The Tree of Sex consortium set out to build a database that would make the data accessible and downloadable, using a common ontology describing the traits of interest Tables 1 and 2. For vertebrates, our coverage has focused on species with information about the mechanism of sex determination.
