| influence of physical stress, distress cues, and predator kairomones on the foraging behavior of ozark zigzag salamanders, plethodon angusticlavius. | an animal's response to environmentally induced stress can have important fitness consequences. for example, an animal may reduce activity in response to stress related to increased predation risk, but this response carries the potential cost of missed foraging or mating opportunities. we used laboratory bioassays to determine whether ozark zigzag salamanders, plethodon angusticlavius, decreased their feeding behavior following increased levels of threat-related stress. stress level was manipula ... | 2004 | 15222967 |
