Review of Hydrobiology RESEARCH ARTICLE www.reviewofhydrobiology.com 4,1: 47-58 (2011) 47 Species records of order Odonata (Insecta) and their habitat quality from Turkey NİLGÜN KAZANCI 1* 1 Hacettepe University, Science Faculty, Biology Department, Hydrobiology Section, Beytepe, Ankara, Turkey [ * Corresponding author: Prof. Dr. Nilgün Kazancı, nilgunkazanci@gmail.com] ABSTRACT 1. Ten odonate species were recorded from various lentic and lotic aquatic ecosystems in different parts of Turkey. Two of them, Caliaeschna microstigma and Cordulegaster picta are in threatened categories. 2. Information on the ecology of ten species are lacking in literature. The quality of habitats of ten species were given with physicochemical variables and with results of metrics based on benthic macroinvertebrates. 3. All recorded species deserve special attention due to habitat destruction caused by pollution, residential and industrial developments, agriculture, aquaculture, energy production, natural system modiications, hydrological alterations, severe weather conditions, invasive species and climate change.
