Trait compensation and cospecialization in a freshwater snail: size, shape and antipredator behaviour

  title={Trait compensation and cospecialization in a freshwater snail: size, shape and antipredator behaviour},
  author={Thomas J Dewitt and Andrew Sih and Jeffrey A. Hucko},
  journal={Animal Behaviour},
We examined relationships between individual differences in antipredator behaviour and prey morphological characters (size, shape) that influence prey vulnerability. Behavioural responses of Physa gyrina to chemical cues associated with predation by crayfish Orconectes rusticus, were assayed in the laboratory for 6 days over a 13-day period. Snails displayed consistent, individually repeatable responses to the predation cues, including hiding (refuge use) and substratum avoidance (crawling to… CONTINUE READING
