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 930 total…

…showed last 75 words of 930 total…the presence of alternative prey reduced predation on both. The observations show that environmental context modifies biotic interactions between stream dwelling, insects and that cold season interactions (Pennuto 2003). Literature Cited Abrahams, M. and L.M.
