Forest fragmentation is a prevalent issue both globally and in temperate forests of the Northeast US, forming edges with warmer, drier, and windier microclimates that alter carbon storage potential. In particular, soil respiration, the largest terrestrial to atmospheric carbon flux, varies along edge-to-interior gradients. However, current literature on forest edge soil respiration often overlooks the distinct responses of autotrophic and heterotrophic respiration. While autotrophic respiration by plant roots releases recently sequestered carbon, heterotrophic respiration by microbes releases carbon from soil organic matter, potentially reducing long-term carbon storage. Using Harvard Forest’s CLimate Interactions with Forest Fragmentation (CLIFF) experiment, I explored both components of soil respiration in a temperate forest edge-to-interior gradient under drought, ambient, and irrigated conditions. I measured soil respiration across six plots using a LI-COR 8100/7810 alongside soil moisture and soil temperature taken by handheld probes. At 0m and 30m from the edge, I measured untrenched collars for total soil respiration and trenched collars for heterotrophic soil respiration. I hypothesized that (1) changes in soil respiration along the edge-to-interior gradient would be driven by changes in heterotrophic respiration and (2) the ambient plot would have the greatest percent heterotrophic respiration. Across all treatments, total and heterotrophic soil respiration both declined from the forest interior to the edge, with the strongest responses in the irrigated plots and weakest responses in the drought plots. I also modeled Q10 values, a measure of temperature sensitivity, finding that 0m collars had lower Q10s than 30m collars and trenched collars had slightly lower Q10s than their untrenched counterparts. These findings on heterotrophic and autotrophic soil respiration at forest edges can help make carbon storage models more precise and dynamic as they continually include data on how each kind of respiration responds to different conditions such as those tested at CLIFF.
