Richness and distribution of reptiles and amphibians in the tropical lowland habitats of Mt. Agad-Agad, Iligan City, Southern Philippines

Knowledge of Philippine herpetofauna is progressively increasing. However, there are still areas in the country that are poorly understood and remain unexplored, particularly in the southern Philippines. Mt. Agad-Agad in Iligan City (Lanao del Norte Province) is a secondary lowland evergreen tropical rainforest in the southern portion of the northern Mindanao region, popular with the general public and a biologically important mountain ecosystem. Herein, we present the species richness and distribution of herpetofauna using standardized sampling methods. We documented 37 species of amphibians and reptiles, recording 20 Philippine-endemic species, three exotic anurans, two threatened reptiles, and one unidentified species of lizard. Species richness was higher in a mixed agricultural area (18 species, n = 108 individuals) compared to secondary growth forest (17 species, n = 86 individuals). This research provides baseline information on the herpetofauna from Mt. Agad-Agad, and additional herpetological knowledge on the distribution and ecology of amphibians and reptiles from the northern Mindanao region

Species Composition and Assessment of Sphingidae in Mt. Agad-Agad, Iligan City, Philippines

Sphingidae (Hawkmoth or Sphinxmoth) is a known bioindicator that is naturally af-fected by environmental issues such as deforestation and pollution. Members of this family are widely distributed in Southeast Asia and play vital roles as indicators of habitat quality and biomass degradation. This study highlights the diversity and as-sessment of hawkmoths of Mt. Agad-Agad (Sitio Langinlanon, Barangay Puga-an) on Iligan City. Two sampling stations were established, the upper and lower Mt. Agad-Agad. Light trap sampling using 2 ×3 m2white silk cloth and 500 watts light bulb was established in selected points of the sampling stations. Six species belong-ing to four genera were recorded of which two species, Acosmeryx socratesand Pol-yptychus trilineatusphilippinensis, were found very rare in the area. Station 2 (lower Mt. Agad-Agad) had the highest number of species recorded compared to Station 1 (upper Mt. Agad-Agad). However, there is no significant difference between the two (t=0.59, critical t=2.2281, p=0.56) sampling stations in terms of species composi-tion. Moreover, two species from the genus Ambulyxare the endemic species ob-served, viz, A. bakeriand A. wilemani
