Multiple microbial guilds mediate soil methane cycling along a wetland salinity gradient
Estuarine wetlands harbor considerable carbon stocks, but rising sea levels could affect their ability to sequester soil carbon as well as their potential to emit methane (CH4). While sulfate loading from seawater intrusion may reduce CH4 production due to the higher energy yield of microbial sulfate reduction, existing studies suggest other factors are likely at play. Our study of 11 wetland complexes spanning a natural salinity and productivity gradient across the San Francisco Bay and Delta found that while CH4 fluxes generally declined with salinity, they were highest in oligohaline wetlands (ca. 3-ppt salinity). Methanogens and methanogenesis genes were weakly correlated with CH4 fluxes but alone did not explain the highest rates observed. Taxonomic and functional gene data suggested that other microbial guilds that influence carbon and nitrogen cycling need to be accounted for to better predict CH4 fluxes at …

AmeriFlux: Its Impact on our understanding of the ‘breathing of the biosphere’, after 25 years
For over two decades, the AmeriFlux network has quantified the breathing of the biosphere, as defined by measuring the flux densities of carbon dioxide and water vapor exchange between ecosystems and the atmosphere. The network includes natural and managed ecosystems that span broad climatic and ecological gradients. In this review, we provide an overview of key discoveries by this network and highlight important open questions. Such discoveries are possible through the network's shared and open access database that is used to interpret these fluxes; it includes a comprehensive set of carbon dioxide and water vapor flux measurements and a complementary set of biophysical variables, including meteorological and soil conditions, along with structural and functional properties of the ecosystems. Topics covered in this paper include interannual variability, trends and magnitude of carbon dioxide fluxes …

Towards sharing water better with near real-time maps on evaporative water use by crops and natural vegetation
The combination of advancements in evapotranspiration theory, eddy covariance flux measurements of water vapour and satellite remote sensing are putting technology on the verge of producing information on evapotranspiration with unprecedented coverage and resolution. The OpenET project provides this information to farmers and land and water managers for better water practice.

Comparison between the trapezoid method and two energy balance models (TSEB and 3SEB) to estimate evapotranspiration of a tree-grass ecosystem
Tree-grass ecosystems (TGEs) comprise nearly 1/6th of Earth's surface in many climates while being biodiversity hotspots. These transitory landscapes dominate global biogeochemical cycles and are one of the most sensitive to global climate change. Indeed, these issues, combined with increasing pressures from agricultural land conversion, livestock grazing, and wildfires, require better characterization of these ecosystems.Actually, the performance of evapotranspiration (ET) remote sensing algorithms tends to have more significant uncertainties in these landscapes due to the poor representation of both (i) the vertical multiple-layered vegetation strata (ie, overstory with tree/shrub canopies over a herbaceous understory) having distinct phenological variations and bare soil, and (ii) the openness of the horizontally distributed high vegetation, causing inherent pixel heterogeneity at the conventional satellite scale.

On the Relationship Between Aquatic CO2 Concentration and Ecosystem Fluxes in Some of the World’s Key Wetland Types
To understand patterns in CO2 partial pressure (PCO2) over time in wetlands’ surface water and porewater, we examined the relationship between PCO2 and land–atmosphere flux of CO2 at the ecosystem scale at 22 Northern Hemisphere wetland sites synthesized through an open call. Sites spanned 6 major wetland types (tidal, alpine, fen, bog, marsh, and prairie pothole/karst), 7 Köppen climates, and 16 different years. Ecosystem respiration (Reco) and gross primary production (GPP), components of vertical CO2 flux, were compared to PCO2, a component of lateral CO2 flux, to determine if photosynthetic rates and soil respiration consistently influence wetland surface and porewater CO2 concentrations across wetlands. Similar to drivers of primary productivity at the ecosystem scale, PCO2 was strongly positively correlated with air temperature (Tair) at most sites. Monthly average PCO2 tended to peak …

Alternating Conditional Expectations: Introducing A non‐parametric statistical method to interpret long‐term greenhouse gas flux measurements over semi‐arid and wetland ecosystems
We explore the potential of using a non‐parametric statistical method called Alternating Conditional Expectations, ACE, to quantify functional relationships in biogeosciences. Here, ACE is used to quantify the non‐linear and multi‐faceted responses of greenhouse gas fluxes to a set of biophysical forcings, when the shapes of those response surfaces are unknown. We evaluated the statistical method over two contrasting ecosystems and two contrasting time steps. One case involved quantifying the biophysical controls of water vapor and carbon dioxide (CO2) fluxes over a semi‐arid oak savanna using daily integrated fluxes. The other case evaluated the responses of CO2 and methane (CH4) flux measurements to a set of biophysical forcings at a restored tidal wetland using thirty‐minute averages. The statistical model, based on 4 independent variables, explained up over 90% of the variation in daily integrated …

Net fluxes of broadband shortwave and photosynthetically active radiation complement NDVI and near infrared reflectance of vegetation to explain gross photosynthesis …
A significant challenge in global change research is understanding how vegetation interacts with the environment to influence ecosystem gross primary productivity (GPP) through carbon assimilation. One emerging objective is to consistently predict GPP fluctuations worldwide by establishing a robust scaling relationship between GPP measured at flux towers and satellite spectral reflectance data. However, a major hurdle in achieving this goal is the discrepancy in spatial resolution between early satellite measurements and eddy flux measurements. By using a large set of growing season data covering 100 site-years in North and Central America, we explored the potential of transforming incident and reflected shortwave (Rg) and photosynthetically active radiation (PAR) measurements into a broadband normalized difference vegetation index (NDVI) and near-infrared (NIR) reflectance of vegetation (NIRv) which …
