Red-backed salamander ( Plethodon cinereus, Green) populations in the spruce-fir forest region of northern Maine were studied. during the summers of 1971 and 1972 to obtain information on nesting ecology and. to determine the effects of low level DDT residues on reproductive parameters. Study areas received 3 applications of DDT at 1.12 kg per hectare between 1958 and. 1964 and, residues of 70 to 270 ppb of DDT and its metabolites persisted in salamanders in 1972.
