<p>Freshwater rock pools formed due to erosion and weathering in outcrops are known to act as essential frog breeding habitats. In the northern part of the Western Ghats-Sri Lanka biodiversity hotspot, large freshwater rock pools are shown to be important for adult stage of three species of frogs: Jaladhara Skittering Frog (<i>Euphlyctis jaladhara</i>), Nilphamari Narrow-mouthed Frog (<i>Microhyla nilphamariensis</i>), and Common Indian Treefrog (<i>Polypedates maculatus</i>). Previous studies have thus recommended conservation of existing rock pools and restoration or creation of rock pools for amphibian conservation, in light of reduced rock pool availability due to rapid conversion of outcrops to orchards. To this end, knowledge of tadpole ecology in the rock pools is essential for further research and conservation actions. We assessed the influence of abiotic (pool size, monsoon progression) and biotic (predator abundances) factors on occurrence and abundance of tadpoles of the three species by periodically monitoring the ephemeral freshwater rock pools in lateritic plateaus of the northern Western Ghats. Tadpole occurrences and abundances were negatively associated with monsoon progression, and not associated with predator abundances for all species, while they were positively associated with rock pool size, species-specifically.</p>
