Scaling Individual Tree Transpiration With Thermal Cameras Reveals Interspecies Differences To Drought Vulnerability
Javadian, M., Aubrecht, D. M., Fisher, J. B., Scott, R. L., Burns, S. P., Diehl, J. L., Munger, J. W., Richardson, A. D.

Understanding tree transpiration variability is vital for assessing ecosystem water-use efficiency and forest health amid climate change, yet most landscape-level measurements do not differentiate individual trees. Using canopy temperature data from thermal cameras, we estimated the transpiration rates of individual trees at Harvard …

A New Coupled Biogeochemical Modeling Approach Provides Accurate Predictions of Methane and Carbon Dioxide Fluxes Across Diverse Tidal Wetlands

Tidal wetlands provide valuable ecosystem services, including storing large amounts of carbon. However, the net exchanges of carbon dioxide (CO2) and methane (CH4) in tidal wetlands are highly uncertain. While several biogeochemical models can operate in tidal wetlands, they have yet to be parameterized and validated against high-frequency, …

Performance Evaluation Of Ukesm1 For Surface Ozone Across The Pan-Tropics

Surface ozone monitoring sites in the tropics are limited, despite the risk that surface ozone poses to human health, tropical forest and crop productivity. Atmospheric chemistry models allow us to assess ozone exposure in unmonitored locations and evaluate the potential influence of changing policies and climate on air quality, …

Remote Sensing Of Seasonal Variation Of Lai And Fapar In A Deciduous Broadleaf Forest
Lee, L. X., Whitby, T. G., Munger, J. W., Stonebrook, S. J., Friedl, M. A.

Climate change is affecting the phenology of terrestrial ecosystems. In deciduous forests, phenology in leaf area index (LAI) is the primary driver of seasonal variation in the fraction of absorbed photosynthetically active radiation (fAPAR), which drives photosynthesis. Remote sensing has been widely used to estimate LAI and fAPAR. …

Agriculture Accentuates Interannual Variability In Water Fluxes But Not Carbon Fluxes, Relative To Native Prairie, In The U.S. Corn Belt
Schreiner-McGraw, A. P., Wood, J. D., Metz, M. E., Sadler, E. J., Sudduth, K. A.

To decrease negative environmental impacts associated with row crop agriculture, the conversion of conventional agricultural lands to no-till with cover crops or to restored prairie in the Midwest U.S. has been proposed and has the potential to alter hydrologic behavior. Our understanding of the impacts of this conversion on water …

Warming and drought weaken the carbon sink capacity of an endangered paleoendemic temperate rainforest in South America
Perez‐Quezada, J. F., Barichivich, J., Urrutia‐Jalabert, R., Carrasco, E., Aguilera, D., Bacour, C., Lara, A.

Measurements of ecosystem carbon (C) fluxes in temperate forests are concentrated in the Northern Hemisphere, leaving the functionally diverse temperate forests in the Southern Hemisphere underrepresented. Here, we report three years (February 2018-January 2021) of C fluxes, studied with eddy-covariance and closed chamber techniques, …

The Effect Of Water Management And Ratoon Rice Cropping On Methane Emissions And Yield In Arkansas
Leavitt, M., Moreno-García, B., Reavis, C. W., Reba, M. L., Runkle, B. R.

Sustainable intensification of rice farming is crucial to meeting human food needs while reducing environmental impacts. Rice production represents 8% of all anthropogenic emissions of CH4, a potent greenhouse gas. Cultivation practices that minimize the number of days the rice fields are flooded, such as irrigation using the alternate …
