Landscape-Scale Variability In Soil Organic Carbon Storage In The Central Canadian Arctic
Campeau, A. B., Lafleur, P. M., Humphreys, E. R.

Campeau, A. B., Lafleur, P. M. and Humphreys, E. R. 2014. Landscape-scale variability in soil organic carbon storage in the central Canadian Arctic. Can. J. Soil Sci. 94: 477–488. Arctic soils constitute a vast, but poorly quantified, pool of soil organic carbon (SOC). The uncertainty associated with pan-Arctic SOC …

Modeling Respiration From Snags And Coarse Woody Debris Before And After An Invasive Gypsy Moth Disturbance
Renninger, H. J., Carlo, N., Clark, K. L., Schäfer, K. V.

Although snags and coarse woody debris are a small component of ecosystem respiration, disturbances can significantly increase the mass and respiration from these carbon (C) pools. The objectives of this study were to (1) measure respiration rates of snags and coarse woody debris throughout the year in a forest previously defoliated …

Contrasting Effects Of Invasive Insects And Fire On Ecosystem Water Use Efficiency
Clark, K. L., Skowronski, N. S., Gallagher, M. R., Renninger, H., Schäfer, K. V. R.

We used eddy covariance and meteorological measurements to estimate net ecosystem exchange of CO2 (NEE), gross ecosystem production (GEP), evapotranspiration (Et), and ecosystem water use efficiency (WUEe; calculated as GEP / Et during dry canopy conditions) in three upland forests …

Tree-Ring δ 13c Tracks Flux Tower Ecosystem Productivity Estimates In A Ne Temperate Forest
Belmecheri, S., Maxwell, R. S., Taylor, A. H., Davis, K. J., Freeman, K. H., Munger, W. J.

We investigated relationships between tree-ring δ13C and growth, and flux tower estimates of gross primary productivity (GPP) at Harvard Forest from 1992 to 2010. Seasonal variations of derived photosynthetic isotope discrimination (Δ13C) and leaf intercellular CO2 concentration (c i ) showed significant increasing trends for the …

Long-Term Variability And Environmental Control Of The Carbon Cycle In An Oak-Dominated Temperate Forest
Xie, J., Chen, J., Sun, G., Chu, H., Noormets, A., Ouyang, Z., John, R., Wan, S., Guan, W.

Our understanding of the long-term carbon (C) cycle of temperate deciduous forests and its sensitivity to climate variability is limited due to the large temporal dynamics of C fluxes. The goal of the study was to quantify the effects of environmental variables on …

Net Ecosystem Methane And Carbon Dioxide Exchanges In A Lake Erie Coastal Marsh And A Nearby Cropland
Chu, H., Chen, J., Gottgens, J. F., Ouyang, Z., John, R., Czajkowski, K., Becker, R.

Net ecosystem carbon dioxide (FCO2) and methane (FCH4) exchanges were measured by using the eddy covariance method to quantify the atmospheric carbon budget at a Typha– and Nymphaea-dominated freshwater marsh (March 2011 to March 2013) and a soybean cropland (May 2011 to May 2012) in northwestern …
