The effects of different temperature treatments on the sediment reworking by Ruditapes decussatus and R. philippinarum (cm, mean ± SE): (a) Surface boundary roughness (SBR), (b) mean mixed depth of luminophores’ redistribution (f-SPILmean), (c) median mixed depth of luminophores’ redistribution (f-SPILmedian), and (d) maximum mixed depth of luminophores’ redistribution (f-SPILmax), at day 12. For clarity, jitter has been applied to the × = argument of the plot function to avoid overplotting. For comparison, measurements in the absence of animals are presented (grey, control). constant temperature; heat wave; n = 20.
