Evaluating A Lagrangian Inverse Model For Inferring Isotope Co2 Exchange In Plant Canopies
Santos, M., Santos, E., Wagner-Riddle, C., Brown, S., Stropes, K., Staebler, R., Nippert, J.

Thermal Imaging In Plant And Ecosystem Ecology: Applications And Challenges
Still, C., Powell, R., Aubrecht, D., Kim, Y., Helliker, B., Roberts, D., Richardson, A. D., Goulden, M.

Temperature is a primary environmental control on ecological systems and processes at a range of spatial and temporal scales. The surface temperature of organisms is often more relevant for ecological processes than air temperature, which is much more commonly measured. Surface temperature influences—and is influenced by—a range …

Precipitation Mediates Sap Flux Sensitivity To Evaporative Demand In The Neotropics
Grossiord, C., Christoffersen, B., Alonso-Rodríguez, A. M., Anderson-Teixeira, K., Asbjornsen, H., Aparecido, L. M., Carter Berry, Z., Baraloto, C., Bonal, D., Borrego, I., Burban, B., Chambers, J. Q., Christianson, D. S., Detto, M., Faybishenko, B., Fontes, C. G., Fortunel, C., Gimenez, B. O., Jardine, K. J., Kueppers, L., Miller, G. R., Moore, G. W., Negron-Juarez, R., Stahl, C., Swenson, N. G., Trotsiuk, V., Varadharajan, C., Warren, J. M., Wolfe, B. T., Wei, L., Wood, T. E., Xu, C., McDowell, N. G.

Transpiration in humid tropical forests modulates the global water cycle and is a key driver of climate regulation. Yet, our understanding of how tropical trees regulate sap flux in response to climate variability remains elusive. With a progressively warming climate, atmospheric evaporative demand [i.e., vapor pressure deficit (VPD)] …

Effects Of Disturbance On The Carbon Dioxide Balance Of An Anthropogenic Peatland In Northern Patagonia
Valdés-Barrera, A., Kutzbach, L., Celis-Diez, J. L., Armesto, J. J., Holl, D., Perez-Quezada, J. F.

Peatlands are characterized by their large carbon (C) storage capacity and represent important C sinks globally. In southern Chile, young peatlands (few centuries old) have originated due to clearcutting or fire at forest sites with high precipitation on poorly drained soils. These novel ecosystems are called anthropogenic peatlands …

Contrasting Temperature Sensitivity Of CO2 Exchange In Peatlands Of The Hudson Bay Lowlands, Canada
Helbig, M., Humphreys, E. R., Todd, A.

It remains uncertain how the net ecosystem CO2 exchange (NEE) of diverse peatlands will respond to warming. Here we compare five years of eddy covariance measurements of NEE and estimates of gross primary productivity and ecosystem respiration between a fen dominated by deciduous vegetation and an adjacent bog with evergreen vegetation …

Actual evapotranspiration and the pattern of soil water extraction of a soybean (Glycine max) crop
Curto, L., Covi M., Gassmann, M.I.

Crop evapotranspiration knowledge during different phenological stages helps determine crop water requirements and water use efficiency. This study was intended to estimate evapotranspiration of soybean grown under field conditions using the water balance equation and to characterize root water extraction across …

Extremely Dry Environment Down-Regulates Nighttime Respiration Of A Black Spruce Forest In Interior Alaska
Nagano, H., Ikawa, H., Nakai, T., Matsushima-Yashima, M., Kobayashi, H., Kim, Y., Suzuki, R.

A Novel Correction For Biases In Forest Eddy Covariance Carbon Balance

Merging a mechanistic enzymatic model of soil heterotrophic respiration into an ecosystem model in two AmeriFlux sites of northeastern USA
Sihi, D, Davidson, E.A., Chen, M, Savage, K.E., Richardson, A.D., Keenan, T.F., Hollinger, D. Y.

Heterotrophic respiration (Rh), microbial processing of soil organic matter to carbon dioxide (CO2), is a major, yet highly uncertain, carbon (C) flux from terrestrial systems to the atmosphere. Temperature sensitivity of Rh is often represented with a simple Q10 function in ecosystem models and earth system models (ESMs), sometimes …

The Effect Of Land Cover Type And Structure On Evapotranspiration From Agricultural And Wetland Sites In The Sacramento–San Joaquin River Delta, California
Eichelmann, E., Hemes, K. S., Knox, S. H., Oikawa, P. Y., Chamberlain, S. D., Sturtevant, C., Verfaillie, J., Baldocchi, D. D.

Water is a limited and valuable resource in California. A large proportion of the fresh water for southern California is supplied by the Sacramento and San Joaquin rivers. With recent efforts to restore large areas of land in the Sacramento–San Joaquin Delta region from farmland to managed wetlands, it is important to investigate …
