Introduction
The purpose of Pennuto's (2003) experiment is to show seasonal changes in insect and predator behavior. Pennuto (2003) determines whether seasons, predator existence or alternative prey, availability affected prey patch use when faced with a sit-and-wait predator from streams in southern Maine. In addition to the abrupt morality rate of predator, movement is assessed as a possible mechanisms, explaining patch use by prey in different seasons. What Pennuto (2003) is trying to prove is; can seasons control …showed first 75 words of 968 total…
