Welton, who also wrote scientific papers extensively about the lizards in the Philippines, including the discovery of the new species Varanus bitatawa, said the discovery highlights the uniqueness and conservation priority of the Cordillera faunal region
Of the seven species recorded through key informant interviews (KII), four are endemic of which two are Philippine endemic and two Mindanao Faunal Region
Middle Ordovician conodonts from the Atlantic Faunal Region
and the evolution of key conodont genera.

"The Visayan spotted deer is the largest endemic species of the Western Visayas faunal region

This is in accordance with Wallace's (1876) criteria that faunal regions
