Enhancement of total sediment carbon oxidation due to increased microbial degradation in the presence of irrigated burrows (E1 = Ciox/Cdox) and reworking (Er = Crox/Cdox) as a function of abundance of Nereis diversicolor and Arenicola marina. Other variables are fixed: L = 20 cm, Lb = 20 cm, Lox = 0.3 cm, r = 0.3 cm, Box = 0.2 cm, A1 = 20 and A2 = 10. See text for further details (modified from Kristensen and Homier[59]).
