Effect of test and acclimation temperature on survival of cohorts of C. imicola and C. bolitinos . Survival was assessed 6 hours after each cohort was exposed to the test temperature for 2 hours. (A) Survival at high temperatures by C. imicola; (B) survival at high temperatures by C. bolitinos; (C) survival at low temperatures by C. imicola; (D) survival at low temperatures by C. bolitinos. In each case, the mean ± 1 S.E. are shown (n = 5) for each test and acclimation temperature combination.
