The carbon balance pivot point of southwestern U.S. semiarid ecosystems: Insights from the 21st century drought
Scott, R.L., Biederman, J.A., Hamerlynck, E.P., Barron-Gafford, G.

Global-scale studies indicate that semiarid regions strongly regulate the terrestrial carbon sink.
However, we lack understanding of how climatic shifts, such as decadal drought, impact carbon sequestration across the wide range of structural diversity in semiarid ecosystems. Therefore, we used eddy covariance measurements to quantify …

Variations in the influence of diffuse light on gross primary productivity in temperate ecosystems
Bohrer, G., Steiner, A.L., Hollinger, D.Y., Suyker, A., Phillips, R.P., Nadelhoffer, K.J.

The carbon storage potential of terrestrial ecosystems depends in part on how atmospheric conditions influence the type and amount of surface radiation available for photosynthesis. Diffuse light, resulting from interactions between incident solar radiation and atmospheric aerosols and clouds, has been postulated to increase carbon …

Carbon Exchange Over Four Growing Seasons For A Subarctic Sedge Fen In Northern Manitoba, Canada
Hanis, K. L., Amiro, B. D., Tenuta, M., Papakyriakou, T., Swystun, K. A.

Net ecosystem exchange of carbon was measured using eddy covariance for four growing seasons at a subarctic hummocky fen in northern Manitoba, Canada. Over a 115 day measurement period each year, cumulative net ecosystem exchange of carbon ranged from a gain of 49 g C m−2 to a loss of 16 g C m−2 with a mean loss of 6 g C m−2 …

Evapotranspiration Of Annual And Perennial Biofuel Crops In A Variable Climate
Abraha, M., Chen, J., Chu, H., Zenone, T., John, R., Su, Y., Hamilton, S. K., Robertson, G. P.

Eddy covariance measurements were made in seven fields in the Midwest USA over 4 years (including the 2012 drought year) to estimate evapotranspiration (ET) of newly established rain-fed cellulosic and grain …

Long-Rotation Sugarcane In Hawaii Sustains High Carbon Accumulation And Radiation Use Efficiency In 2nd Year Of Growth
Anderson, R. G., Tirado-Corbalá, R., Wang, D., Ayars, J. E.

Sugarcane has been a major agronomic crop in Hawaii with an unique, high-yield, two-year production system. However, parameters relevant to advanced, cellulosic biofuel production, such as net ecosystem productivity (NEP) and radiation use efficiency (RUE), have not been evaluated in Hawaii under commercial production. Recent demand …
