With the worldwide decline of amphibians, captive breeding is vital for the long-term conservation of many endangered species. Spindly leg syndrome is a musculoskeletal abnormality commonly associated with captive rearing that results in underdeveloped limbs in newly metamorphosed frogs. Researchers will investigate if calcium or phosphate concentrations in water used to rear tadpoles are factors that limit limb development. A clearer understanding of the causes of this developmental abnormality will improve survival rates in captive amphibians reared for conservation.
