Figure 2. Changes in A). oxidative damage (d-ROMs) andB). non-enzymatic antioxidant capacity (OXY) in the plasma (means ± standard error) in relation to flight-training. Background (BG) levels of d-ROMs and OXY (solid horizontal line ± standard error, dotted lines) were not significantly different for flight-trained and untrained birds (see text) and so were combined. Dietary antioxidants significantly affected only plasma d-ROMs measured after flight (AF) so we discriminate between the two diets (filled or open triangles) for only this time point. Different lower-case letters for the 4 timepoints (BG, PF, AF, RC) for d-ROMs or OXY denote significant pairwise comparisons (Table S1).
