Table 4.
Summary of the numbers of species shared between Chihuahua and neighboring Mexican and American states (not including introduced species). The percent of Chihuahuan species shared by a neighboring state are given in parentheses. Total refers to the total number of species found in Chihuahua and all the neighboring states (i.e., regional species pool) and the number in parentheses in this column is the percent of the regional species pool found in Chihuahua. -- indicates either Chihuahua or the neighboring state has no species in the taxonomic group, thus no value for shared species is provided.
