Amphibians and reptiles represent an important group of vertebrates in Mexico; on a global scale 10% of the biodiversity of these groups is found in the country, attaining extraordinarily high levels of endemism (60.7% and 53.7%, respectively). Species accumulation curves for the three vertebrate taxa (Fig. Mammals, although presenting a flat accumulation curve, were sampled in a small area, and the true fauna is doubtless larger. inventories for plants, reptiles and amphibians, birds, and mammals. 3) indicate that inventories for birds are likely complete.
