| Abstrak/Abstract |
Odonata acts as a natural enemy in the paddy field ecosystem. The Odonata diversity is highly related to habitat conditions. This research analyzed the effect of altitude on the diversity of Odonata in paddy field ecosystems in Sleman Regency, Special Region of Yogyakarta. This research was conducted in Palagan and Cangkringan at four different altitude levels: 160-250 masl, 260-350 masl, 360-450 masl, and 460-550 masl. The Odonata sample was obtained from purposive sampling and identified using the Wendit Flying Dragon reference book. The specimens
obtained were 2,342 individuals, consisting of 13 species, 11 genera, three families, and two suborders. The Shannon-Wiener index showed the highest Odonata diversity index at an altitude of 360-450 masl. In contrast, the evenness index analysis showed that they varied in each altitude coordinate. Correlation analysis showed that the altitude coordinate of the paddy fields was positively correlated with the biodiversity index and evenness index of Odonata, with the correlation value obtained less than 0.5. |
