Ecosystem Carbon And Water Cycling From A Sky Island Montane Forest
Knowles, J. F., Scott, R. L., Minor, R. L., Barron-Gafford, G. A.

“Sky islands” are characteristic of sequential mountain-valley terrain where mountains form an island archipelago rising from surrounding valleys of desert “sea”. At high elevations in the Madrean sky islands of the southwestern United States (USA) and Mexico, mixed evergreen conifer forests occur near the latitudinal extent …

Experimental Harvesting Of Wetland Plants To Evaluate Trade-Offs Between Reducing Methane Emissions And Removing Nutrients Accumulated To The Biomass In Constructed Wetlands
Kasak, K., Valach, A., Rey-Sanchez, C., Kill, K., Shortt, R., Liu, J., Dronova, I., Mander, Ü., Szutu, D., Verfaillie, J., Baldocchi, D.

Constructed wetlands built for water treatment often need biomass harvesting to remove nutrients from the system. Usually harvesting is done during the peak growing season to maximize the amount of nutrients removed from the system. This, however, can create huge methane fluxes that escape from plant tissues to the atmosphere. We …

Wildfire‐Smoke Aerosols Lead To Increased Light Use Efficiency Among Agricultural And Restored Wetland Land Uses In California’S Central Valley
Hemes, K. S., Verfaillie, J., Baldocchi, D. D.

There are few observational studies measuring the ecosystem‐scale productivity effects of changes in incident diffuse photosynthetically active radiation (PARdiffuse), especially related to wildfire smoke. Climate change‐induced increases to the duration and intensity of fire conditions have made smoke a common occurrence across …

Tidal Wetland Gross Primary Production Across The Continental United States, 2000–2019
Feagin, R. A., Forbrich, I., Huff, T. P., Barr, J. G., Ruiz‐Plancarte, J., Fuentes, J. D., Najjar, R. G., Vargas, R., Vázquez‐Lule, A., Windham‐Myers, L., Kroeger, K. D., Ward, E. J., Moore, G. W., Leclerc, M., Krauss, K. W., Stagg, C. L., Alber, M., Knox, S. H., Schäfer, K. V., Bianchi, T. S., Hutchings, J. A., Nahrawi, H., Noormets, A., Mitra, B., Jaimes, A., Hinson, A. L., Bergamaschi, B., King, J. S., Miao, G.

We mapped tidal wetland gross primary production (GPP) with unprecedented detail for multiple wetland types across the continental United States (CONUS) at 16‐day intervals for the years 2000–2019. To accomplish this task, we developed the spatially explicit Blue Carbon (BC) model, which combined tidal wetland cover and field‐based …

Divergent Carbon Cycle Response Of Forest And Grass‐Dominated Northern Temperate Ecosystems To Record Winter Warming

Fire Behavior, Fuel Consumption, And Turbulence And Energy Exchange During Prescribed Fires In Pitch Pine Forests
Clark, K. L., Heilman, W. E., Skowronski, N. S., Gallagher, M. R., Mueller, E., Hadden, R. M., Simeoni, A.

Prescribed fires are conducted extensively in pine-dominated forests throughout the Eastern USA to reduce the risk of wildfires and maintain fire-adapted ecosystems. We asked how fire behavior and fuel consumption during prescribed fires are associated with turbulence and energy fluxes, which affect the dispersion of smoke and transport …

Spatial Heterogeneity In Co2, Ch4, And Energy Fluxes: Insights From Airborne Eddy Covariance Measurements Over The Mid-Atlantic Region
Hannun, R. A., Wolfe, G. M., Kawa, S. R., Hanisco, T. F., Newman, P. A., Alfieri, J. G., Barrick, J., Clark, K. L., DiGangi, J. P., Diskin, G. S., King, J., Kustas, W. P., Mitra, B., Noormets, A., Nowak, J. B., Thornhill, K. L., Vargas, R.

The exchange of carbon between the Earth’s atmosphere and biosphere influences the atmospheric abundances of carbon dioxide (CO2) and methane (CH4). Airborne eddy covariance (EC) can quantify surface-atmosphere exchange from landscape-to-regional scales, offering a unique perspective on carbon cycle dynamics.Weuse extensive airborne …

Atmospheric Vapour And Precipitation Are Not In Isotopic Equilibrium In A Continental Mountain Environment
Mercer, J. J., Liefert, D. T., Williams, D. G.

Isotopic exchange with atmospheric vapour can strongly influence the isotopic values of evaporating surface water bodies (e.g., lakes), influencing our understanding of hydrological processes across aquatic and terrestrial environments. Rather than measure the isotopic values of the atmosphere directly, it is much more common to …
