Energy Availability And Leaf Area Dominate Control Of Ecosystem Evapotranspiration In The Southeastern U.S.
Aguilos, M., Sun, G., Liu, N., Zhang, Y., Starr, G., Oishi, A. C., O'Halloran, T. L., Forsythe, J., Wang, J., Zhu, M., Amatya, D., Baniya, B., McNulty, S., Noormets, A., King, J.

Evapotranspiration (ET) links water, energy, and carbon balances, and its magnitude and patterns are changing due to climate and land use change in the southeastern U.S. Quantifying the environmental controls on ET is essential for developing reliable ecohydrological models for water resources management. Here, we synthesized eddy …

Contrasting Carbon Cycle Responses to Dry (2015 El Niño) and Wet (2008 La Niña) Extreme Events at an Amazon Tropical Forest
Restrepo-Coupe, N., Campos, K. S., Alves, L. F., Longo, M., Wiedemann, K. T., de Oliveira, R. C., Aragao, L. E., Christoffersen, B. O., Camargo, P. B., Figueira, A. M., Ferreira, M. L., Oliveira, R. S., Penha, D., Prohaska, N., da Araujo, A. C., Daube, B. C., Wofsy, S. C., Saleska, S. R.

Land surface models diverge in their predictions of the Amazon forest’s response to climate change-induced droughts, with some showing a catastrophic collapse of forests, while others simulating resilience. Therefore, observations of tropical ecosystem responses to real-world droughts and other extreme events are needed. We report …

Dynamics of evapotranspiration from concurrent above- and below-canopy flux measurements in a montane Sierra Nevada forest
Wolf, S., Paul-Limoges, E., Sayler, D., Kirchner, J. W.

Evapotranspiration (ET) from the land surface to the atmosphere is a major component of Earth’s water cycle, and comprises both transpiration (T) of xylem water from plants and evaporation (E) of water from soils and vegetation surfaces. These two component fluxes respond differently to changes in temperature, water availability …

Higher Phosphorus And Water Use Efficiencies And Leaf Stoichiometry Contribute To Legume Success In Drylands
Acuña‐Acosta, D. M., Castellanos, A. E., Llano‐Sotelo, J. M., Sardans, J., Peñuelas, J., Romo‐Leon, J. R., Koch, G. W.

Legumes are essential plants in dryland ecosystems worldwide because they increase nitrogen availability, so their understanding is vital for improving knowledge and modelling in the face of climate change.
This work studies the differences in resource use efficiency and their relationship with photosynthetic, photochemical, bioelemental, …

Anomalous Wet Summers And Rising Atmospheric Co 2 Concentrations Increase The Co 2 Sink In A Poorly Drained Forest On Permafrost
Ueyama, M., Iwata, H., Nagano, H., Kukuu, N., Harazono, Y.

At the northern high latitudes, rapid warming, associated changes in the hydrological cycle, and rising atmospheric CO2 concentrations, [CO2], are observed at present. Under rapid environmental changes, it is important to understand the current and future trajectories of the CO2 budget in high-latitude ecosystems. In this …

Methane And Carbon Dioxide Emissions From The Forest Floor Of A Black Spruce Forest On Permafrost In Interior Alaska
Ueyama, M., Iwata, H., Endo, R., Harazono, Y.

High-latitude warming has stimulated CO2 and CH4 emissions from permafrost peatland. This study evaluated growing season CH4 and CO2 emissions from a forest floor of a lowland black spruce forest on permafrost in interior Alaska using automated-closed chambers, anaerobic incubation of peat soils and next-generation sequencing. The …

Martínez-Núñez, E., Castellanos, A. E., Basant, S., Ortega, C., Wilcox, B. P., Yépez, E. A., Rodríguez, J. C., Romo-León, J. R.

Background: Plants in arid ecosystems exhibit adaptive traits to periodic droughts. It is predicted that droughts will become more frequent and intense due to global change. Studying plant ecophysiological traits will help understand their adaptations to water limitations. In arid ecosystems of northwestern Mexico, evergreen and …

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. …
