N2O Emissions From Two Agroecosystems: High Spatial Variability And Long Pulses Observed Using Static Chambers And The Flux‐Gradient Technique
Waldo, S., Russell, E. S., Kostyanovsky, K., Pressley, S. N., O'Keeffe, P. T., Huggins, D. R., Stöckle, C. O., Pan, W. L., Lamb, B. K.

With the addition of nitrogen (N), agricultural soils are the main anthropogenic source of N2O, but high spatial and temporal variabilities make N2O emissions difficult to characterize at the field scale. This study used flux‐gradient measurements to continuously monitor N2O emissions at two agricultural fields under different …

The Spatial Variability Of Actual Evapotranspiration Across The Amazon River Basin Based On Remote Sensing Products Validated With Flux Towers
Paca, V. H., Espinoza-Dávalos, G. E., Hessels, T. M., Moreira, D. M., Comair, G. F., Bastiaanssen, W. G.

Actual evapotranspiration (ET) is a major component of the water balance. While several international flux measurement programs have been executed in the tropical rain forest of the Amazon, those measurements represent the evaporative process at a few selected sites only. The aim of this study is to obtain the spatial distribution …

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 …
