Influence of Timber Harvesting Alternatives on Forest Soil Respiration and Its Biophysical

We investigated the variability of soil respiration and several potential regulatory factors and mod-eled their interrelationships from May to August over a 5-year period in oak forests subjected to alternative harvesting treatments as part of the Missouri Ozark Forest Ecosystem Project (MOFEP). Treatments included even-aged management (EAM), uneven-aged management (UAM), and no-harvest management (NHM) and were imple-mented 7–8 years prior to this study. Summer mean soil respiration did not differ among the treatments, possibly because of changes in treat-ment differences in the separate months and years that tended to cancel each other out when aver
