Abstract. Methane (CH4) emissions from natural landscapes constitute roughly half of global CH4 contributions to the atmosphere, yet large uncertainties remain in absolute magnitude and seasonality emission quantities drivers. Eddy covariance (EC) measurements flux are ideal for constraining ecosystem-scale due quasi-continuous high-temporal-resolution measurements, coincident carbon dioxide, water, energy lack ecosystem disturbance, increased availability datasets over last decade. Here, we...
Abstract. Riverine wetlands are created and transformed by geomorphological processes that determine their vegetation composition, primary production soil accretion, all of which likely to influence C stocks. Here, we compared ecosystem stocks (trees, downed wood) N different types riverine (marsh, peat swamp forest mangroves) whose distribution spans from an environment dominated river forces estuarine coastal processes. We also estimated sequestration rates mangroves on the basis...
Abstract Coastal salt marshes store large amounts of carbon but the magnitude and patterns greenhouse gas (GHG; i.e., dioxide (CO 2 ) methane (CH 4 )) fluxes are unclear. Information about GHG from these ecosystems comes studies sediments or at ecosystem‐scale (eddy covariance) tidal creeks unknown. We measured concentrations in water, water quality, meteorological parameters, sediment CO efflux, fluxes, plant phenology; all half‐hour intervals over 1 year. Manual creek flux measurements...
Abstract We mapped tidal wetland gross primary production (GPP) with unprecedented detail for multiple types across the continental United States (CONUS) at 16‐day intervals years 2000–2019. To accomplish this task, we developed spatially explicit Blue Carbon (BC) model, which combined cover and field‐based eddy covariance tower data into a single Bayesian framework, used super computer network remote sensing imagery (Moderate Resolution Imaging Spectroradiometer Enhanced Vegetation Index)....
Abstract Mangroves cover less than 0.1% of Earth’s surface, store large amounts carbon per unit area, but are threatened by global environmental change. The capacity mangroves productivity could be characterized their canopy greenness, this property has not been systematically tested across gradients mangrove forests and national scales. Here, we analyzed time series Normalized Difference Vegetation Index (NDVI), mean air temperature total precipitation between 2001 2015 (14 years) to...
Abstract. Over the past decade, Brazil has experienced severe droughts across its territory, with important implications for soil moisture dynamics. Soil variability a direct impact on agriculture, water security and ecosystem services. Nevertheless, there is currently little information how different biomes responds to drought. In this study, we used satellite data from European Space Agency, 2009 2015, analyze differences in responses drought each biome of Brazil: Amazon, Atlantic Forest,...
Abstract. Deforestation and degradation of wetlands are important causes carbon dioxide emissions to the atmosphere. Accurate measurements (C) stocks sequestration rates needed for incorporating into conservation restoration programs with aim preventing emissions. Here, we assessed whole ecosystem C (trees, soil downed wood) N riverine (mangroves, marshes peat swamps) within La Encrucijada Biosphere Reserve in Pacific coast Mexico. We also estimated mangroves on basis accumulation....

Abstract Salt marsh ecosystems are underrepresented in process‐based models due to their unique location across the terrestrial–aquatic interface. Particularly, role of leaf nutrients on canopy photosynthesis (F A ) remains unclear, despite relevance for regulating vegetation growth. We combined multiyear information canopy‐level and eddy covariance measurements with surface hyperspectral remote sensing (CSHRS) quantify spatial temporal variability F a temperate salt marsh. found that showed...
Abstract Measurements of atmospheric ammonia (NH 3 ) concentrations and fluxes are limited in coastal regions the eastern U.S. In this study, continuous high temporal resolution measurements (5s) NH were recorded using a cavity ring‐down spectrometer temperate tidal salt marsh at St Jones Reserve (Dover, DE). Micrometeorological variables measured an eddy covariance system which is part AmeriFlux network (US‐StJ). Soil, plant, water chemistry also analyzed to characterize sources sinks . A...

Information about GHG from these ecosystems comes studies sediments or at ecosystem-scale (eddy covariance) tidal creeks unknown. We measured concentrations in water, water quality, meteorology, sediment CO efflux, fluxes, plant phenology; all half-hour time-steps over one year.

Introduction In the world, 33% of soils are degraded, and 2.9 million people affected by land degradation, with problems associated food security, conflicts over natural resources, migration different impacts on men or women. To support sustainable soil management, it is necessary to include women’s contributions Sciences; their achievements academic performance still need be represented. Women in Science represent 30% worldwide. Mexico, only 24% top positions For commitment Sciences for...

Terrestrial-aquatic interfaces such as salt marshes, mangroves, and similar wetlands provide an optimum natural environment for the sequestration long-term storage of carbon (C) from atmosphere, commonly known coastal blue carbon. There are over 4 million acres marsh in US half these along east coast US. Due to anthropogenic activities, this area presents greatest nitrogen (N) pollution problem ecosystems U.S. part atmospheric N deposition, runoff, riverine export. Ammonia (NH3) is most...
