Abstract Previous studies showed that Fejervarya cancrivora tadpoles were salt-tolerant (up to 24 parts per thousand [ppt] in the field and 35 ppt in the laboratory) but metamorphosed only at or below 6.6 ppt. We hypothesized that the discrepancy in salt tolerance of tadpoles is due to a mixture of results drawn from short- and long-term experiments and different acclimation procedures, which needed to be re-examined. We compared the salinity tolerance of acclimated and nonacclimated tadpoles and assessed salinity effects on growth, development, and metamorphosis among tadpoles of F. cancrivora throughout larval period. In Experiment 1, we determined 48-h tadpole survivorship by assigning 40 tadpoles to one of the 24 treatments ranging from 3-ppt to 30-ppt salinity. In Experiment 2, we assigned tadpoles to 3–15-ppt salinity at intervals of 3 ppt and monitored tadpole growth and development through metamorphosis. In Experiment 3, we exposed 15 tadpoles to a stepwise increase of salinity (i.e., 2 ppt every ...
