Comparison Of Tree-Ring Growth And Eddy Covariance-Based Ecosystem Productivities In Three Different-Aged Pine Plantation Forests
McKenzie, S. M., Pisaric, M. F., Arain, M. A.

Forests play a major role in the global carbon cycle. Understanding the dynamics of the forest carbon cycle and its driving factors is challenging. This study utilized dendrochronology and long-term (2003 to 2017) eddy covariance (EC) carbon flux data to investigate the relationships between tree growth and gross and net ecosystem …

Temporal Trends In Methane Emissions From A Small Eutrophic Reservoir: The Key Role Of A Spring Burst
Waldo, S., Beaulieu, J. J., Barnett, W., Balz, D. A., Vanni, M. J., Williamson, T., Walker, J. T.

Waters impounded behind dams (i.e., reservoirs) are important sources of greenhouses gases (GHGs), especially methane (CH4), but emission estimates are not well constrained due to high spatial and temporal variability, limitations in monitoring methods to characterize hot spot and hot moment emissions, and the limited number of studies …

Spring Onsets Of A Young Forest In Interior Alaska Determined Based On Time‑Lapse Camera And Eddy Covariance Measurements
KAWASHIMA, S., UEYAMA, M., OKAMURA, M., HARAZONO, Y., IWATA, H., KOBAYASHI, H.

Spring phenology is essential in modeling the carbon balance of high‑latitude ecosystems and is possibly sensitive to climate change. In the present study, we evaluated the onset of the growing season for three species (paper birch, bog blueberry, and bog Labrador tea) in interior Alaska from 2012 to 2019 using photos taken using …

Relative humidity gradients as a key constraint on terrestrial water and energy fluxes
Kim, Y., Garcia, M., Morillas, L., Weber, U., Black, T. A., Johnson, M. S.

Earth’s climate and water cycle are highly dependent on terrestrial evapotranspiration and the associated flux of latent heat. Although it has been hypothesized for over 50 years that land dryness becomes embedded in atmospheric conditions through evaporation, underlying physical mechanisms for this land–atmosphere coupling remain …

Long Term Effects Of Fire On The Soil Greenhouse Gas Balance Of An Old-Growth Temperate Rainforest
Perez-Quezada, J. F., Urrutia, P., Olivares-Rojas, J., Meijide, A., Sánchez-Cañete, E. P., Gaxiola, A.

Forest fires can cause great changes in the composition, structure and functioning of forest ecosystems. We studied the effects of a fire that occurred >50 years ago in a temperate rainforest that caused flooding conditions in a Placic Andosol to evaluate how long these effects last; we hypothesized that the effects of fire on …

Turbulent Momentum Flux Behavior Above A Fire Front In An Open-Canopied Forest
Heilman, W. E., Clark, K. L., Bian, X., Charney, J. J., Zhong, S., Skowronski, N. S., Gallagher, M. R., Patterson, M.

Atmospheric turbulent circulations in the vicinity of wildland fire fronts play an important role in the transfer of momentum into and out of combustion zones, which in turn can potentially affect the behavior and spread of wildland fires. The vertical turbulent transfer of momentum is accomplished via individual sweep, ejection, …

Effects Of Land-Use Change And Drought On Decadal Evapotranspiration And Water Balance Of Natural And Managed Forested Wetlands Along The Southeastern Us Lower Coastal Plain
Aguilos, M., Sun, G., Noormets, A., Domec, J., McNulty, S., Gavazzi, M., Minick, K., Mitra, B., Prajapati, P., Yang, Y., King, J.

Forested wetlands are important in regulating regional hydrology and climate. However, long-term studies on the hydrologic impacts of converting natural forested wetlands to pine plantations are rare for the southern US. From 2005-2018, we quantified water cycling in two post-harvest and newly-planted loblolly pine (Pinus taeda) …
