Database with biogeographic and mating system information

The datafile contains all of the data on biogeography and outcrossing rates. The column heading definitions are as follows: year: Year in which the study was published reference: Reference containing estimates of outcrossing rate family: Plant family name of the species studied genus: Genus-level name of the species studied species: species-level name of the species studied m.d.g: Broad taxonomic category; m = monocot, d = dicot, g = gymnosperm latitude: Degree of latitude (range from 0 – 90) for the population in which outcrossing rate was measured. If multiple populations were studied for a given species this value is the average of the population-level latitudes. Latitudes are expressed as decimal degrees and the absolute value from the equator. hemisphere: N = northern hemisphere; S = southern hemisphere biome: Biome categories ordered by net ecosystem productivity: 1 = Desert/arid scrub; 2 = Temperate grasslands; 3 = Shrubland/chaparral; 4 = Taiga; 5 = Tropical savannah; 6 = Temperate deciduous forest and rainforest; 7 = Tropical seasonal forest; 8 = Tropical rainforest growth: Growth form categories: 1 = Herbaceous; 2 = Vine; 3 = Schrub; 4 = Tree; 5 = Varies life.history: Life history categories: 1 = Annual; 2 = Biennial; 3 = Semelparous perennial; 4 = Iteroparous perennial; 5 = Varies si: 0 = Self-incompatible; 1 = Self-compatible mean.tm: Outcrossing rate. If multiple populations were studied for a given species this value is the average of the population-level outcrossing rates. References: A list of references used to gather biological data on species
