Title : Evidence for edge enhancements of soil respiration in temperate forests
Journal : Geophysical Research Letters
Comment :
Forest fragmentation impacts carbon uptake and storage, however, the magnitude and direction of fragmentation impacts on soil respiration remain poorly characterized. They quantify soil respiration rates along edge-to-interior transects in two temperate broad-leaf forests in the eastern US that vary in climate, species composition, and soil type. They observe average soil respiration rates 15-26% higher at the forest edge compared to the interior, corresponding to large gradients in soil temperature. These results suggest that estimates of soil respiration in the temperate forest region may be underestimating biological emissions of carbon dioxide.
