    • Abstract


      Gravimetric estimation of absorption efficiency in amphibians is a timeconsuming process and still subject to technical errors. The need for the application of indirect methods requiring no quantitative recovery of feces is indicated. From 41 values reported for 11 amphibian species, it is observed that nitrogen content of food is significantly (P<0·001) and positively correlated (>0·9) with absorption efficiency. From the obtained regression equation (absorption efficiency=49·615+4·596 nitrogen), the per cent efficiency can be predicted with 3·748 standard error.
