Fig. 2: Comparison of swimming activity and tank use behavior before and after the simulated predatory attack on predator-exposed fish, in non-parasitized and parasitized groups.

Fig. 2

A Total traveled distance in mm. B Mean velocity in body length (BL) per second. C Angular velocity in degrees per second. D Time (s) spent in the center zone, an indicator of boldness. Samples are grouped by parasite status, population (glacial Þristikla and spring-fed Galtaból), and time period (before (BT) and after (AT) the simulated predatory attack). P values from significant (p < 0.05) post-hoc comparisons are shown above square brackets (full results are provided in Supplementary Table 2). Note: control fish which were never exposed to the predator are not shown in this figure. Significance was assessed by a post hoc of multiple comparison test on the population by Period by Parasite interaction.
