Abundance and biodiversity of Odonata (dragonflies and damselflies) at Lata Renyuk, Jeli, Kelantan

This study focuses on analyzing the abundance and diversity of Odonata (dragonflies and damselflies) Lata Renyuk, Jeli, Kelantan. The main objectives of the study are to assess the diversity of Odonata and to provide a checklist of species present in the area. Sampling was carried out opportunistically using sweep nets along the banks of the Renyuk River at two specific sites, labeled as A and B, throughout a period of one month. A total of 11 species and 174 individuals were noted from the selected study sites. Additionally, Lata Renyuk was found to be home to 7 species and 2 families. The evaluation of the conservation status using the IUCN Red List determined that the populations are currently classified as least concern. After determining how many individuals were examined using the Shannon-Wiener diversity index, it was discovered that Site A had a maximum potential diversity of H'max = 3.97 and a low species diversity of H' = 0.931. Site B, on the other hand, showed a peak diversity value of H'max = 4.097 and a medium level of species diversity with H' = 1.410, suggesting stable environmental circumstances suitable for the evaluation of species diversity. Environmental aspects such as exposure to sunlight and water flow dynamics were identified as factors influencing the distribution of Odonata. The results emphasize the significance of habitat characteristics in shaping Odonata diversity and stress the importance of implementing conservation strategies in similar ecosystems. Further research is strongly recommended to delve into additional taxa and to evaluate the impact of human activities on Odonata populations.
