Repeated freeze-thaw cycles increase extractable, but not total, carbon and nitrogen in a Maine coniferous soil
This dataset contains processed data for the publication Patel et al. 2021. "Repeated freeze-thaw cycles increase extractable, but not total, carbon and nitrogen in a Maine coniferous soil". Geoderma. https://doi.org/10.1016/j.geoderma.2021.115353. Northeastern North America has been experiencing warmer winters with reduced snow accumulation, with more frequent winter freeze-thaw cycles. We conducted a laboratory experiment to investigate how increased frequency of freeze-thaw cycles (FTC) would alter soil C and N availability. Organic (O) and mineral (B) horizon soils were collected from a coniferous forest in Maine, processed to exclude roots, and then frozen in the laboratory (-10 °C) with one (FTC-1), two (FTC-2), or six (FTC-6) thaw periods (+5 °C). Soils were analyzed for extractable ammonium (NH4-N), water extractable organic carbon (WEOC), carbon dioxide flux (respiration), and total C and N. Extractable NH4-N increased following FTC (all levels), for both horizons. While WEOC concentrations did not change for FTC vs. control, the WEOC in O horizons had a lower SUVA254 in FTC soils compared to control, indicating a stronger microbial influence (i.e., microbial cell lysis) in these soils after FTC. Respiration in O horizon soils decreased post-incubation and did not differ between FTC and Control soils. In the B horizon, however, FTC soils showed greater respiration than Control soils, suggesting that the newly available nutrients may have stimulated microbial activity. In contrast to these results, total C and N remained unaltered by FTC, presumably because the FTC disturbances represented mostly a translocation of C and N from one pool into another, and losses due to respiration were too small to significantly influence the large TC and TN pools. The effect of FTC on NH4-N did not change with FTC frequency, suggesting that a single FTC is sufficient to alter both C and N availability and/or quality, and that additional FTC may not have a significant further
Variability in soil and litter arthropod populations in the Soil Freezing Study plots at the Hubbard Brook Experimental Forest, 2009-2010
Climate models for the northeastern United States (U.S.) over the next century project an increase in air temperature between 2.8 and 4.3 °C and a decrease in the average number of days per year when a snowpack will cover the forest floor. Warmer temperatures may benefit some litter arthropods by allowing them to expand their ranges and to increase their rates of reproduction. However, a reduction in snowpack depth and duration could offset these changes and lead to increased arthropod mortality because the snowpack plays an important role in insulating arthropods from freezing temperatures. We evaluated these potential changes by measuring arthropod abundance in the Soil Freezing Study plots at the Hubabard Brook Experimental Forest. These data were gathered as part of the Hubbard Brook Ecosystem Study (HBES). The HBES is a collaborative effort at the Hubbard Brook Experimental Forest, which is operated and maintained by the USDA Forest Service, Northern Research Station.
