Abstract
Total surface respiration (Rs) was measured over a diurnal cycle in precommercially thinned and unthinned western Newfoundland balsam fir (Abies balsamea (L.) Mill.) on 15–16 July 2002. Soil temperatures (Ts), soil moisture potentials (Psi s), and Rs were recorded hourly. Average hourly Rs in the thinned stand was significantly lower than in the unthinned stand. Differences in Rs between thinned and unthinned stands changed with time. Only thinned stand hourly Rs was significantly related to Ts and Psi s.
