This research is designed to test how sublethal exposure to copper affects tadpole
predator-escape behavior and how quickly tadpoles recover. After exposure, tadpoles were
separated. Escape behavior was recorded for two-thirds of exposed tadpoles while one-third of
the exposed population was measured weekly to determine growth and recovery.
Control tadpoles were consumed within 15 minutes whereas those exposed to higher
concentrations were consumed at a slower rate, which does not support the hypotheses.
Although the rate of predation was lower, tadpoles exposed to higher Cu concentrations were on
average, 1.47 cm in total body length. Those exposed to 0.93 mg/L averaged 0.86 cm. After
being placed into clean water, treatment tadpoles recovered after 20 days.
