Observed and simulated distribution of stenobiomic bovid species (BSI = 1) across biomes.

sp., number of species; %, proportion of species with BSI = 1 in relation to total number of species in each biome; p, probability in each biome of the proportion of species with BSI = 1 being greater than or equal to (plain) or lower than or equal to (italics) the observed proportion in Bovidae.
