Variations in oxygen uptake with variations in temperature were measured on undisturbed salt‐marsh muds taken from Georgia, the Bay of Fundy, and the eastern shore of Nova Scotia. Mud temperatures were measured in the marsh. Natural temperature variations were about twice as great in Georgia as in Nova Scotia. Q 10 values for respiration determined in any one season varied from 1 to 4, tending to be lower in southern marshes and marshes located nearer low water level. In all marshes, seasonal changes of mud respiration were correlated with changes in energy supply and with temperature. Considering periods of days or weeks rather than months, the southern mud organisms show more stability under conditions of changing temperature than the northern ones. This may be due to better stirring by large animals and the absence of freezing in the south.
