Movements and Winter Behavior of Eurycea bislineata (Amphibia, Urodela, Plethodontidae)

In Preble County, Ohio, 20 Eurycea bislineata were tagged subcutaneously with Co60 and monitored between April, 1969 and February, 1970. Average movement between April and November, 1969 was 5.27 m. The inability to locate individuals frequently did not permit the plotting of home ranges, but the average area in which movement took place was less than 14 m2. Salamanders began moving to winter retreats when the stream temperature dropped below 7.0 C. Within these retreats as many as 27 salamanders were found in an area of 30.0 cm2. All salamanders were active and feeding during the winter.
