1. The numbers in this row represent the number of species found at this latitude across all five longitudes. Thus, a total of 135 species are found at the latitude 32o 00’ N. Some species are found at only one transect, others may be found at multiple transects, but only one entry (X) is made in the table.

2 Does note include aquatic (Order Cetaceae) or terrestrial (Order Carnivora Families Odobenidae and Phocidae) marine mammals. The two easternmost points are the only locations in the entire matrix with a marine environment.
