Predation of N. melanostomus on amphipods within a 3 h time-period where either single species (white, n = 11) or a combination of both species (grey, n = 22) were tested. a Substratum absent. b Substratum present. [Asterisks indicate significant differences at p < 0.05 (*), p < 0.01 (**), p < 0.001 (***)]. Boxplots represent 25 to 75 % (boxes) and 5 to 95 % percentiles (whiskers). Circles represent outliers (exceeding 1.5 interquartile range)
