Figure 2

The influence of temperature on (A) the activity (B) the distance travelled (over 24 h), (C) the velocity and (D) the fractal dimension of H. germanica. The box represents the first, second and third quartiles and the whiskers extend to 1.5 times the interquartile range; values outside this range are represented by open circles. Number of replicates are 30, 23, 30, 25, 15, 69, 28 and 26 for 6, 12, 18, 24, 30, 32, 34 and 36 °C respectively. Due to the absence of motion it was impossible to estimate fractal dimension at 32, 34 and 36 °C. Letters above the boxes (‘a’, ‘b’, ‘c’ and ‘d’) identify significant different groups (Dunn test, p < 0.05).
