Odonata diversity as a Bioindicator of Habitat quality in an urban landscape: Insights from Tripura University campus, Northeast India

Abstract: Odonates (dragonflies and damselflies) are widely recognised as ecological bioindicators due to their sensitivity to environmental conditions and habitat integrity. This study documents the diversity and community structure of Odonata within the semi-urban landscape of Tripura University campus, Northeast India, over a one-year period (April 2024-March 2025). A total of 33 species belonging to 25 genera and 5 families were recorded, comprising 23 species of Anisoptera and 10 of Zygoptera, representing 44% of the known odonate fauna of Tripura. The family Libellulidae was the most dominant, with Rhyothemis variegata identified as the only eudominant species. Diversity indices, the Shannon index (2.335) and the Simpson index (0.8288), indicated moderate to high diversity, whereas low evenness (0.3129) reflected community dominance by a few generalist species. The presence of both pollution-sensitive and pollution-tolerant taxa highlights habitat heterogeneity and potential anthropogenic impacts. Distribution patterns revealed a predominantly clumped assemblage, linked to habitat patchiness and resource concentration. The results underscore the ecological value of urban green spaces in sustaining odonate biodiversity and provide a baseline for long-term monitoring and regional conservation strategies.
