Abstract

This study was conducted to describe the morphology, habitat preference, diet, and population density estimates of Woodworth's fanged frog (Limnonectes woodworthi, Taylor) in the Mudspring area, Mt. Makiling. Field observations were focused on morphometry, preferred habitat types, diet using Bull's method, and population density using Bailey's triple-catch method and Petersen's method. The average adult Limnonectes woodworthi measures about 64.1mm (range: 42mm-84mm) in SVL; ED-6.8mm (3mm-10.1mm); SnL-11.3mm (5mm-20mm); FILL-96.7mm (62mm-125mm); FLL-35.8mm (20mm-49.5mm); TiL-72.3mm (49mm-92mm) in tibia length (average:); TyD-4.2mm (2.5mm-8.5mm); HL-25.7mm (11mm-39mm); and HB-20.9mm (11mm-31mm). Limnonectes woodworthi prefers to inhabit rock boulders and leaf litter compilations near the river banks. They consume mainly ants, termites, mites, and caterpillar larvae, which are commonly available on their preferred habitat. The estimated population density is 33 individuals per month per 21,600 meters. There were close correlational trends between morphometry and diet, diet and population density, and rainfall and population density. These parameters studied are essential for the management of conservation programs for future benefit of the species. A more detailed follow-up study is to complete a one-year period or more is recommended.
