Table 2 Results of mixed-effects models (Fish ID as random effect) testing for the effects of robotic predator attack, period (before and after triggering the robotic predato), population (glacial Þristikla and spring-fed Galtaból fish), effect of parasites and all interactions on swimming activity (Total Traveled Distance, Angular Velocity, and Mean Velocity) and the tank use (Center Duration, and Distance to Predator) in stickleback fish

From: Interplay between antipredator behavior, parasitism, and gut microbiome in wild stickleback populations
