Abstract

Amphibians are important ecological indicators due to their sensitivity to environmental changes and habitat disturbances. The present study assessed the diversity and population dynamics of amphibians in Bulandshahr district, Uttar Pradesh, India. Field surveys were conducted across agricultural lands, wetlands, ponds, grasslands, riverbanks, and semi-urban habitats from March 2024 to February 2025 using visual encounter surveys, call count surveys, and transect sampling methods. A total of 11 amphibian species belonging to 4 families and 8 genera were recorded during the investigation. The family Dicroglossidae showed maximum dominance, followed by Bufonidae and Microhylidae. Species richness and population density were highest during the monsoon season due to increased breeding activity and moisture availability. Shannon-Wiener diversity index indicated moderate to high amphibian diversity across study sites. The Indian Bullfrog (Hoplobatrachus tigerinus) and Skittering Frog (Euphlyctis cyanophlyctis) were the most abundant species, while the Marbled Balloon Frog (Uperodon systoma) showed relatively lower abundance. Habitat destruction, pesticide use, wetland degradation, urban expansion, and water pollution were identified as major threats affecting amphibian populations in the region. Seasonal fluctuations significantly influenced species abundance and reproductive activities. Amphibians were found to play important ecological roles in pest control and nutrient cycling within agroecosystems. The present study highlights the ecological importance of amphibians in Bulandshahr and emphasizes the need for habitat conservation, sustainable agricultural practices, and long-term biodiversity monitoring programs. Effective conservation strategies involving local communities and governmental agencies are essential for protecting amphibian diversity in rapidly changing agricultural landscapes of western Uttar Pradesh.
