Large Uptake Of Atmospheric Ocs Observed At A Moist Old Growth Forest: Controls And Implications For Carbon Cycle Applications
Rastogi, B., Berkelhammer, M., Wharton, S., Whelan, M. E., Itter, M. S., Leen, J. B., Gupta, M. X., Noone, D., Still, C. J.

Diurnal and vertical patterns of carbonyl sulfide (OCS) and CO2 mixing ratios above and within a 60‐m‐tall old‐growth temperate forest are presented. Canopy air from four different heights was sampled in situ using a continuous integrated cavity output spectroscopy analyzer during August–September 2014. Measurements revealed …

Ecosystem Fluxes Of Carbonyl Sulfide In An Old-Growth Forest: Temporal Dynamics And Responses To Diffuse Radiation And Heat Waves
Rastogi, B., Berkelhammer, M., Wharton, S., Whelan, M. E., Meinzer, F. C., Noone, D., Still, C. J.

Carbonyl sulfide (OCS) has recently emerged as a tracer for terrestrial carbon uptake. While physiological studies relating OCS fluxes to leaf stomatal dynamics have been established at leaf and branch scales and incorporated into global carbon cycle models, the quantity of data from ecosystem-scale field studies remains limited. …

Using Imaging Spectroscopy To Detect Variation In Terrestrial Ecosystem Productivity Across A Water-Stressed Landscape
DuBois, S., Desai, A. R., Singh, A., Serbin, S. P., Goulden, M. L., Baldocchi, D. D., Ma, S., Oechel, W. C., Wharton, S., Kruger, E. L., Townsend, P. A.

A central challenge to understanding how climate anomalies, such as drought and heatwaves, impact the terrestrial carbon cycle, is quantification and scaling of spatial and temporal variation in ecosystem gross primary productivity (GPP). Existing empirical and model‐based satellite broadband spectra‐based products have been …

The Physics And Ecology Of Mining Carbon Dioxide From The Atmosphere By Ecosystems
Baldocchi, D., Penuelas, J.

Reforesting and managing ecosystems have been proposed as ways to mitigate global warming and offset anthropogenic carbon emissions. The intent of our opinion piece is to provide a perspective on how well plants and ecosystems sequester carbon. The ability of individual plants and ecosystems to mine carbon dioxide from the atmosphere, …

Members of the genus Methylobacter are inferred to account for the majority of aerobic methane oxidation in oxic soils from a freshwater wetland
Smith, G. J., Angle, J. C., Solden, L. M., Borton, M. A., Morin, T. H., Daly, R. A., Johnston, M. D., Stefanik, K. C., Wolfe, R., Bohrer, G., Wrighton, K. C.

Microbial carbon degradation and methanogenesis in wetland soils
generate a large proportion of atmospheric methane, a highly potent greenhouse
gas. Despite their potential to mitigate greenhouse gas emissions, knowledge about
methane-consuming methanotrophs is often limited to lower-resolution single-gene
surveys that fail to …

Microtopography Alters Hydrology, Phenol Oxidase Activity and Nutrient Availability in Organic Soils of a Coastal Freshwater Forested Wetland
Minick, K., Kelley, A., Miao, G., Li, X., Noormets, A., Mitra, B., King, J.S.

Hummock-hollow microtopography is a unique feature ofwetland ecosystems, but our understanding ofits effects on soil carbon and nutrient cycling is limited. We investigated effects of microtopography on hydrology, phenol oxidase activity (POX) and nutrient availability in a freshwater forested wetland of coastal North Carolina. Water …

Upscaling Transpiration In Diverse Forests: Insights From A Tropical Premontane Site
Moore, G. W., Orozco, G., Aparecido, L. M., Miller, G. R.

Upscaling water use of individual trees to stands using sap flux techniques is a common method for partitioning site water balance, but few such studies have occurred in the tropics. Increasing interests in the role of tropical forests in global cycles have spurred upscaling studies in natural tropical forests, which present challenges …
