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 …

Gross Primary Production, Ecosystem Respiration, And Net Ecosystem Production In A Southeastern South American Salt Marsh
Bautista, N. E., Gassmann, M. I., Pérez, C. F.

Identifying ecosystems with high carbon uptake is essential to establish protection policies that mitigate the increase of greenhouse gasses due to human activities. Although salt marshes cover small continental areas, they assimilate atmospheric CO2 more efficiently than other terrestrial ecosystems. An atmospheric CO2 flux data …

Tree water fluxes across Panama

Tree water use is the dominant terrestrial hydrologic flux globally, and has a dominant regulatory influence over the carbon cycle. Sap flow through the tree is also a useful model diagnostic for FATES-Hydro. Our objective is to quantify variation in tree water use at three sites across a rainfall gradient in Panama. Our ultimate …

Remote Sensing Products Validated by Flux Tower Data in Amazon Rain Forest
Victor Hugo da Motta Paca, Gonzalo E. Espinoza-Dávalos, Rodrigo da Silva,Raphael Tapajós, Avner Brasileiro dos Santos Gaspar

This work compares methods of climate measurements, such as those used to measure evapotranspiration, precipitation, net radiation, and temperature. The satellite products used were compared and evaluated against flux tower data. Evapotranspiration was validated against the SSEBop monthly and GLEAM daily and monthly products, respectively, …

Heat and drought impact on carbon exchange in an age‑sequence of temperate pine forests
Arain, M.A., Xu, B., Brodeur, J.J., Khomik, M., Peichl, M., Beamesderfer, E., Restrepo‑Coupe, N., Thorne, R.

Most North American temperate forests are plantation or regrowth forests, which are actively managed. These forests are in different stages of their growth cycles and their ability to sequester atmospheric carbon is affected by extreme weather events. In this study, the impact of heat and drought events on carbon sequestration in …

Effects Of Variable Retention Harvesting On Canopy Transpiration In A Red Pine Plantation Forest
Bodo, A. V., Arain, M. A.

Variable Retention Harvesting (VRH) is a forest management practice applied to enhance forest growth, improve biodiversity, preserve ecosystem function and provide economic revenue from harvested timber. There are many different forms and compositions in which VRH is applied in forest ecosystems. In this study, the impacts of four …
