  1. Pair-wise tests of the effects of season and treatment (mayfly taxon or insect-exclusion) on the algal communities on the insect-excluded bricks (control) and in the gut contents of the two mayflies (Baetis and Rhithrogena). p (perm), possible permutations. p (MC), Monte Carlo p values. Statistically significant p values (<0.05) are highlighted in bold font.
