The final paper from our Konkan lateritic plateau fieldwork in 2022 is out now in the journal Aquatic Ecology!

We found presence of tadpoles and their 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.
We found presence of tadpoles and their 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.

In this work, we looked at the freshwater rockpools on the rocky outcrops, to see how their size, monsoon progression and presence of predators influence the tadpoles in them.


These pools, formed due to erosion and weathering in outcrops are critical frog breeding habitats. We observed tadpoles of three species of frogs: Jaladhara Skittering Frog (Euphlyctis jaladhara), Nilphamari Narrow-mouthed Frog (Microhyla nilphamariensis), and Common Indian Treefrog (Polypedates maculatus).


Our previous studies have 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. This necessitated more knowledge of tadpole ecology for further research and conservation actions.

We found presence of tadpoles and their 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.
