Science and Products
Biological and mineralogical controls over cycling of low molecular weight organic compounds along a soil chronosequence
Low molecular weight organic compounds (LMWOC) represent a small but critical component of soil organic matter (SOM) for microbial growth and metabolism. The fate of these compounds is largely under microbial control, yet outside the cell, intrinsic soil properties can also significantly influence their turnover and retention. Using a...
McFarland, Jack; Waldrop, Mark P.; Strawn, Daniel; Creamer, Courtney; Lawrence, Corey R.; Haw, Monica Warming effects of spring rainfall increase methane emissions from thawing permafrost
Methane emissions regulate the near‐term global warming potential of permafrost thaw, particularly where loss of ice‐rich permafrost converts forest and tundra into wetlands. Northern latitudes are expected to get warmer and wetter, and while there is consensus that warming will increase thaw and methane emissions, effects of increased...
Neumann, Rebecca B.; Moorberg, C.J.; Lundquist, J.D.; Turner, J.C.; Waldrop, Mark P.; McFarland, Jack W.; Euskirchen, E.S.; Edgar, C.W.; Turetsky, M.R. Extreme CO2 disturbance and the resilience of soil microbial communities
Carbon capture and storage (CSS) technology has the potential to inadvertently release large quantities of CO2 through geologic substrates and into surrounding soils and ecosystems. Such a disturbance has the potential to not only alter the structure and function of plant and animal communities, but also soils, soil microbial communities,...
McFarland, Jack W.; Waldrop, Mark P.; Haw, Monica Estimating aboveground biomass in interior Alaska with Landsat data and field measurements
Terrestrial plant biomass is a key biophysical parameter required for understanding ecological systems in Alaska. An accurate estimation of biomass at a regional scale provides an important data input for ecological modeling in this region. In this study, we created an aboveground biomass (AGB) map at 30-m resolution for the Yukon Flats ecoregion...
