Radiocarbon-Based Partitioning of Soil Respiration in an Old-Growth Coniferous Forest

Creator:

Taylor, Adam J., Lai, Chun-Ta, Hopkins, Francesca M., Wharton, Sonia, Bible, Ken, Xu, Xiaomei, Phillips, Claire, Bush, Susan, and Ehleringer, James R.

Abstract:

Temperate forests play an important role in the global carbon cycle, and are thought to currently be a sink for atmospheric CO₂. However, we lack understanding of the drivers of forest carbon accumulation and loss, hampering our ability to predict carbon cycle responses to global change. In this study, we...

A Numerical Examination of ¹⁴CO₂ Chamber Methodologies for Sampling at the Soil Surface

Creator:

Egan, Jocelyn, Nickerson, Nick, Phillips, Claire, and Risk, Dave

Abstract:

Radiocarbon is an exceptionally useful tool for studying soil-respired CO₂, providing information about soil carbon turnover rates, depths of production, and the biological sources of production through partitioning. Unfortunately, little work has been done to thoroughly investigate the possibility of inherent biases present in current measurement techniques, like those present...
