Honest Signaling in Aggressive Contests Between Ozark Zigzag Salamanders (Plethodon Angusticlavius)
… behavior that occurs in territorial contests in terrestrial salamanders, is an honest indicator of aggressive intent. In staged contests between pairs of Ozark zigzag salamanders (Plethodon angusticlavius), individuals that performed bites spent more time exhibiting ATR prior to biting than …
