Diversity of Insects in Mount Daguma, Mindanao Island, Philippines: A Multivariate Analysis on the Community Structure of Class Coleoptera and Odonata

The conduct of this study aimed to survey the communities of class insecta in Mount Daguma, Mindanao Island. The specific objective of the study was to Evaluate the Species composition and abundance of Coleoptera and Odonata in the area; (2) Evaluate the Species Richness, Species Diversity, Relative abundance, and Evenness; and (3) examine the relationship of the abundance and diversity of insects and the physicochemical factors in the area and identify factors that pose as threat to the status of Coleoptera and Odonata in the area. The results have shown that Mount Daguma has high levels of biodiversity (1 - D = 0.9372, D = 3.031) and the most ecologically diverse site was Kamengan Falls ( 1 - D = 0.09207 H = 2.696 ) . 10 (32.25%) of the 31 observed species are endemic to the Philippines and 8 (25.80%) are oriental species. The multivariate analysis has shown that the physicochemical parameters of the area influence the community structure of Coleoptera and Odonates in the area. In conclusion, Mount Daguma is a biodiversity-rich ecosystem which is home to several endemic species of Coleoptera and Odonata. The conditions of the habitat within Mount Daguma plays a major role in the community structure of Coleptera and Odonata.
