Hydrologic Response To Precipitation Pulses Under And Between Shrubs In The Chihuahuan Desert, Arizona
Moran, M. S., Hamerlynck, E. P., Scott, R. L., Stone, J. J., Holifield Collins, C. D., Keefer, T. O., Bryant, R., DeYoung, L., Nearing, G. S., Sugg, Z., Hymer, D. C.

Observations of the temporal and spatial distribution of poststorm soil moisture in open shrublands and savannas are limited, yet they are critical to understanding the interaction and feedback between moisture distribution and canopies. The objective of this analysis was to study the hydrologic impacts of precipitation pulses on …

Carbon Dioxide And Methane Fluxes From Arctic Mudboils
Wilson, K. S., Humphreys, E. R.

Climate change is expected to alter the Arctic’s carbon (C) balance and changes in these C-rich ecosystems may contribute to a positive feedback on global climate change. Low-center mudboils, a form of patterned ground in the Arctic, are distinct landforms in which the exchange of greenhouse gases between the atmosphere and soil …

Assimilation Exceeds Respiration Sensitivity To Drought: A FLUXNET Synthesis
Schwalm, C. R., Williams, C. A., Schaefer, K., Arneth, A., Bonal, D., Buchmann, N., Chen, J., Law, B. E., Lindroth, A., Luyssaert, S., Reichstein, M., Richardson, A. D.

The intensification of the hydrological cycle, with an observed and modeled increase in drought incidence and severity, underscores the need to quantify drought effects on …

Tree Species Effects On Ecosystem Water-Use Efficiency In A High-Elevation, Subalpine Forest
Monson, R. K., Prater, M. R., Hu, J., Burns, S. P., Sparks, J. P., Sparks, K. L., Scott-Denton, L. E.

Ecosystem water-use efficiency (eWUE; the ratio of net ecosystem productivity to evapotranspiration rate) is a complex landscape-scale parameter controlled by both physical and biological processes occurring in soil and plants. Leaf WUE (lWUE; the ratio of leaf CO2 assimilation rate to transpiration rate) is controlled at short time …

Evaluation Of Methods For Estimating Soil Carbon Dioxide Efflux Across A Gradient Of Forest Disturbance
Sullivan, B. W., Dore, S., Kolb, T. E., Hart, S. C., Montes-Helu, M. C.

Better understanding of variation in soil carbon dioxide (CO2) efflux caused by measurement techniques is needed, especially over gradients of site disturbance, …

Hydraulic Redistribution Of Soil Water By Roots Affects Whole-Stand Evapotranspiration And Net Ecosystem Carbon Exchange
Domec, J., King, J. S., Noormets, A., Treasure, E., Gavazzi, M. J., Sun, G., McNulty, S. G.
  • Hydraulic redistribution (HR) of water via roots from moist to drier portions of the soil occurs in many ecosystems, potentially influencing both water use and carbon assimilation.
  • By measuring soil water content, sap flow and eddy covariance, we investigated the temporal variability of …

Longer Growing Seasons Lead To Less Carbon Sequestration By A Subalpine Forest
Hu, J., Moore, D. J., Burns, S. P., Monson, R. K.

As global temperatures increase, the potential for longer growing seasons to enhance the terrestrial carbon sink has been proposed as a mechanism to reduce the rate of further warming. At the Niwot Ridge AmeriFlux site, a subalpine forest in the Colorado Rocky Mountains, we used a 9‐year record (1999–2007) of continuous eddy …

A significant fraction of Earth consists of mountainous terrain. However, the question of how to monitor the surface–atmosphere carbon exchange over complex terrain has not been fully explored. This article reports on studies by a team of investigators from U.S. universities and research institutes who carried out a multiscale …
