Abstract Details

2007, Master of Science, Miami University, Zoology.
This study investigated the responses of red-backed salamanders ( Plethodon cinereus) to chemical cues from a predator (garter snake, Thamnophis sirtalis) and a competitor (centipede, Scolopocryptops sexspinosus). A trade-off was discovered between avoidance of both chemical cues and thermal preference. In a thermal gradient, presence of either cue caused P. cinereusto alter their thermal preference to avoid the cue. Forced locomotor speeds were increased and feeding rates were decreased by the presence of either chemical cue. Voluntary locomotor speeds and activity were not affected by the presence of either chemical cue, but an increase in temperature, from 15 °C to 25 °C, caused an 86% increase in voluntary speed. P. cinereustends to avoid both predator and competitor cues and favors predator and competitor avoidance over thermal selection when these two demands conflict.
