Species richness and endemism of anurans in lake Duminagat, Mt. Malindang range natural park, Mindanao, Philippines
Abstract
Taking into account that amphibian, specifically Anurans (frogs and toads), are the most threatened group of vertebrates on the planet, a study of Anuran species diversity was conducted in Lake Duminagat, Mt. Malindang Range Natural Park, Misamis Occidental, Philippines. Anurans were collected using random sampling, and the visual encounter technique was used to determine the species richness of amphibians present in the area. With an initial goal of establishing an update about amphibian species diversity in this area, we conducted surveys that resulted in records documenting the occurrence of five species in five genera and five families. All the species (100 %) collected are endemic to the archipelago; these additionally include a Mindanao Faunal Region endemic, Pulchrana grandocula and one Mindanao Island endemic, Ansonia mcgregori. Among the recorded endemic species, two are classified as vulnerable to extinction. The mossy forest had highest species richness (N=4) and calculated species diversity (H’= 1.149) were recorded in the mossy forest. The presence of endemic and formally classified endangered species indicates the need to protect this forest ecosystem as an important habitat resource for endemic western Mindanao amphibian populations.
