Figure 6

Individual surface sediment reworking (mm³ indiv⁻¹ day⁻¹) of H. germanica under different thermal regime. Letters above plots (‘a’, ‘b’, ‘c’) indicate significant differences among measurements (Dunn test, p < 0.05). The box represents the first, second and third quartiles and the whiskers extend to 1.5 times the interquartile range; values outside this range are represented by open circles.
