Abstract

In Preble County, Ohio, 36 Desmognathus fuscus were tagged subcutaneously with Co60 and monitored between April 1969 and June 1970. Between April and November 1969 salamanders had an average home range of 1.4 m2 (0.1 m2-3.6m2. Average weekly movement during this period was 0.49 m (0.3 m-10.2 m). No significant changes in movement were noted when the salamanders were monitored at 24 hr intervals. Salamanders began to move into winter retreats when the stream temperature dropped below 7.0 C. Within these retreats as many as 15 salamanders were found within an area of 30.0 cm2. All salamanders were active and feeding through the winter. In April 1970 5 gravid D. fuscus were radioactively tagged and their movements monitored but the data obtained were inconclusive regarding nesting behavior.
