The Effect Of Water Table Fluctuation On Soil Respiration In A Lower Coastal Plain Forested Wetland In The Southeastern U.S.
Miao, G., Noormets, A., Domec, J., Trettin, C. C., McNulty, S. G., Sun, G., King, J. S.

Anthropogenic and environmental pressures on wetland hydrology may trigger changes in carbon (C) cycling, potentially exposing vast amounts of soil C to rapid decomposition. We measured soil CO2 efflux (Rs) continuously from 2009 to 2010 in a lower coastal plain forested wetland in North Carolina, U.S., …

Consequences Of Cool-Season Drought-Induced Plant Mortality To Chihuahuan Desert Grassland Ecosystem And Soil Respiration Dynamics
P. Hamerlynck, E., L. Scott, R., Barron-Gafford, G. A.

Predicted reductions of cool-season rainfall may expand and accelerate drought-induced plant mortality currently unfolding across the Southwest US. To assess how repeated plant mortality affects ecosystem functional attributes, we quantified net ecosystem CO2 exchange (NEE), ecosystem respiration (Journal: Ecosystems, Volume 16 (7): 1178-1191 (2013), ISBN .

Biological And Physical Influences On Soil 14CO2 Seasonal Dynamics In A Temperate Hardwood Forest
Phillips, C., McFarlane, K.J., Risk, D., Desai, A.R.

While radiocarbon (14C) abundances in standing stocks of soil carbon have been used to evaluate rates of soil carbon turnover on timescales of several years to centuries, soil-respired 14CO2 measurements are an important tool for identifying more immediate responses to disturbance and climate change. …

Extreme Late-Summer Drought Causes Neutral Annual Carbon Balance In Southwestern Ponderosa Pine Forests And Grasslands
Kolb, T., Dore, S., Montes-Helu, M.

We assessed the impacts of extreme late-summer drought on carbon balance in a semi-arid forest region in Arizona. To understand drought impacts over extremes of forest cover, we measured net ecosystem production (NEP), gross primary production (GPP), and total ecosystem respiration (TER) with eddy covariance over five years (2006–10) …

Initial Carbon Dynamics Of Perennial Grassland Conversion For Annual Cropping In Manitoba
Fraser, T. J., Amiro, B. D.

Fraser, T. J. and Amiro, B. D. 2013. Initial carbon dynamics of perennial grassland conversion for annual cropping in Manitoba. Can. J. Soil Sci. 93: 379–391. Sequestering atmospheric carbon in agricultural soil is an attractive option for mitigation of rising atmospheric carbon dioxide concentrations. Perennial crops …

Eddy Covariance Measurements With A New Fast-Response, Enclosed-Path Analyzer: Spectral Characteristics And Cross-System Comparisons
Novick, K., Walker, J., Chan, W., Schmidt, A., Sobek, C., Vose, J.

A new class of enclosed path gas analyzers suitable for eddy covariance applications combines the advantages of traditional closed-path systems (small density corrections, good performance in poor weather) and open-path systems (good spectral response, low power …

Characteristics Of Evapotranspiration From A Permafrost Black Spruce Forest In Interior Alaska
Nakai, T., Kim, Y., Busey, R. C., Suzuki, R., Nagai, S., Kobayashi, H., Park, H., Sugiura, K., Ito, A.

Here, the year 2011 characteristics of evapotranspiration and the energy budget of a black spruce forest underlain by permafrost in interior Alaska were explored. Energy balance was nearly closed during summer, and the mean value of the daily energy balance ratio (the ratio of turbulent energy fluxes to available energy) from June …

Sustained Carbon Uptake And Storage Following Moderate Disturbance In A Great Lakes Forest
Gough, C. M., Hardiman, B. S., Nave, L. E., Bohrer, G., Maurer, K. D., Vogel, C. S., Nadelhoffer, K. J., Curtis, P. S.

Carbon (C) uptake rates in many forests are sustained, or decline only briefly, following disturbances that partially defoliate the canopy. The mechanisms supporting such functional resistance to moderate …

Extreme Drought Effects On Carbon Dynamics Of A Semiarid Pasture
Rajan, N., Maas, S. J., Cui, S.

Environmental and management factors are critical in determining the C source or sink status of agroecosystems. Information on the C dynamics of an ecosystem from source to sink and vice versa are critical in determining the role of that ecosystem in regional and global C balances. We investigated the impact of the 2011 mega-drought …

Landscape And Environmental Controls Over Leaf And Ecosystem Carbon Dioxide Fluxes Under Woody Plant Expansion
Barron-Gafford, G. A., Scott, R. L., Jenerette, G. D., Hamerlynck, E. P., Huxman, T. E.
  1. Many regions of the globe are experiencing a simultaneous change in the dominant plant functional type and regional climatology. We explored how atmospheric temperature and precipitation control leaf- and ecosystem-scale carbon fluxes within a pair of semi-arid …
