ABSTRACT

The order Odonata ("toothed ones") includes some of the most ancient and beautiful insects that ever roamed Earth, as well as some of the largest flying invertebrates ever to have lived. The distribution of various groups and species of Odonata is highly variable. Some genera and species are widespread while others are highly local in their distribution. Some families are restricted to cool streams or rivers, others to ponds or still clear waters, and some to marshy places. The presence of dragonflies and damselflies may be taken as an indication of good ecosystem quality. The odonata fauna sampling is conducted in the period from January-March 2014 including its habitat characteristics, vegetation structure, air temperature and atmospheric humidity. The results will show that the distribution and abundance of odonata will be an indicative increased numbers of species that are found in the three different vegetation sites that offer a wide variety of microhabitats, though dragonflies tend to be much more sensitive to pollution than damselflies.

INTRODUCTION

The order Odonata represents one set of insects that is being widely studied for its potential in indicating environmental quality base on its vegetation types. Studies have included Odonata relationships with water quality (Azrina et al. 2006), biotope quality (Clark &Samways 1996; Clausnitzer 2003) and general species richness (Sahlen&Ekestubbe 2001, Briers & Biggs 2003).

Odonata (dragonflies & damselflies) are attractive insects that are considered important indicators for water quality as well as for general species richness (Corbet 1993; Dolný 2000; Chovanec&Waringer 2001; Sahlén&Ekestubbe 2001; Timmetal. 2001; Mustow 2002). Dragonflies and damselflies are a flagship group, and an important component of ecosystems, in which they can often be top predators.

Their sensitivity to environmental conditions makes odonata excellent biological indicators of environmental conditions (Brown 1991; Clark &Samways 1996; Samways, et al. 2010). The ecological requirements of adults, which are associated with aquatic habitats and terrestrial landscapes, their selectivity of oviposition sites, and the influence of aquatic processes on the larval phase, which leads to their persistence in water, give rise to the familiar associations between each species and its characteristic habitat (Corbet 1993, 1999), making Odonata susceptible to specific types of habitat changes (Corbet 1993; Clark and Samways 1996; Schindler, Fesl, and Chovanec 2003; Foote & Rice Hornung 2005). Many ecosystems have been subjected to great stress from increasing human activity, resulting in many species disappearing before any conservation actions are taken. Since organisms require certain habitats, the knowledge of their relation to their habitat and vegetation is critical for establishing conservation and management plans (Maleque et al. 2006).

By determining number of species or groups of species of odonata, this will be an indication whether it will be a good or poor quality living for odonata on the three different types of vegetation in Ozamiz City: the agro-forested ecosystem, agricultural ecosystem and mangrove ecosystem. The distribution of various groups and species of Odonata is highly variable. Some genera and species are widespread while others are highly local in their distribution. Some families are restricted to cool streams or rivers, others to ponds or still clear waters, and some to marshy places. The presence of dragonflies and damselflies may be taken as an indication of good ecosystem quality (R. M. Olberg, K. R. Venator, & A. M. Worthington,...
