Global-scale studies suggest that dryland ecosystems dominate an increasing trend in the magnitude and interannual variability of land CO2 sink. However, such analyses are poorly constrained by measured exchange drylands. Here we address this observation gap with eddy covariance data from 25 sites water-limited Southwest region North America observed ranges annual precipitation 100-1000 mm, temperatures 2-25°C, records 3-10 years (150 site-years total). Annual fluxes were integrated using...
Soil moisture control on evapotranspiration is poorly understood in ecosystems experiencing seasonal greening. In this study, we utilize a set of multi‐year observations at four eddy covariance sites along latitudinal gradient vegetation greening to infer the ET ‐θ relation during North American monsoon. Results reveal significant seasonal, interannual and ecosystem variations observed directly linked particular, monsoon‐dominated adjust their relation, through changes unstressed plant...
Abstract. Instantaneous evapotranspiration rates and surface water stress levels can be deduced from remotely sensed temperature data through the energy budget. Two families of methods defined: contextual methods, where are scaled on a given image between hot/dry cool/wet pixels for particular vegetation cover, single-pixel which evaluate latent heat as residual balance one pixel independently others. Four models, two (S-SEBI modified triangle method, named VIT) (TSEB, SEBS) applied over...
In the North American monsoon (NAM) region, in‐phase seasonality in precipitation and radiation should lead to corresponding changes catchment hydrologic response its spatiotemporal variability. Nevertheless, relatively little is known on NAM region because of paucity observations. Numerical watershed models, tested against field remote sensing data, can aid identifying patterns controls exerted by climate, soil, vegetation, terrain properties. this study, we utilize a distributed model...
Erythropoietin (EPO) is a cytokine known to have effective cytoprotective action in the brain, particularly ischemic, traumatic, inflammatory, and neurodegenerative conditions. We previously reported neuroprotective effect of low sialic form EPO, Neuro-EPO, applied intranasally roden t models stroke or cerebellar ataxia non-transgenic mouse model Alzheimer's disease (AD). Here we analyzed protective Neuro-EPO APPSwe mice, reference transgenic AD. Mice were administered 3 times day, days week...
Abstract Relatively little is currently known about the spatiotemporal variability of land surface conditions during North American monsoon, in particular for regions complex topography. As a result, role played by land–atmosphere interactions generating convective rainfall over steep terrain and sustaining monsoon still poorly understood. In this study, variation hydrometeorological along large-scale topographic transect northwestern Mexico described. The field experiment consisted daily...
Regional analysis of water use efficiency (WUE) is a relevant method for diagnosing the performance irrigation systems in water-limited environments. In this study, we investigated potential FORMOSAT-2 images to provide spatial estimates WUE over irrigated wheat crops cultivated within semi-arid Yaqui Valley, northwest Mexico. provided us with unique dataset 36 at high resolution (8 m) encompassing growing season from November 2007 May 2008. Time series green leaf area index were derived...
Abstract Due to their large extent and high primary productivity, tropical dry forests (TDF) are important contributors atmospheric carbon exchanges in subtropical regions. In northwest Mexico, a bimodal precipitation regime that includes winter derived from Pacific storms summer the North American monsoon (NAM) couples water availability with ecosystem processes. We investigated net production of TDF using 4.5 year record fluxes obtained eddy covariance method complemented remotely sensed...
Abstract Seasonal vegetation changes during the North American monsoon play a major role in modifying water, energy, and momentum fluxes. Nevertheless, most models parameterize plants as static component or with averaged seasonal variations that ignore interannual differences their potential impact on evapotranspiration ( ET ) its components. Here parameters derived from remote sensing data were coupled hydrologic model at two eddy covariance (EC) sites observations spanning multiple...
This study explores how three distinct preservation techniques affect the microstructure and rheological properties of natural rubber latex. Traditional ammoniated systems were compared against two emerging eco-friendly preservatives developed by AFLatex Technologies, which demonstrated enhanced latex reported in Ammonia-Free Latex Compositions, US Patent Application 63/267,167.2022. 2023. Rheological data modeled using Cross model to capture non-linearity viscosity Krieger–Dougherty...
Abstract The vegetation in the core region of North American monsoon (NAM) system changes dramatically after onset summer rains so that large may be expected surface fluxes radiation, heat, and moisture. Most this lies rugged terrain western Mexico very few measurements these have been made past. Surface energy balance were at seven sites Sonora, Mexico, Arizona during intensive observation period (IOP) Monsoon Experiment (NAME) 2004 to better understand how land change alters flux...
Abstract Water‐limited ecosystems occupy nearly 30% of the Earth, but arguably, controls on their ecosystem processes remain largely uncertain. We analyzed six site years eddy covariance measurements evapotranspiration (ET) from 2008 to 2010 at two water‐limited shrublands: one dominated by winter precipitation (WP site) and another summer (SP site), with similar solar radiation patterns in Northern Hemisphere. determined how physical forcing factors (i.e., net ( R n ), soil water content...

Para entender los procesos de ecosistemas desde un punto vista funcional es fundamental las relaciones entre la variabilidad climática, ciclos biogeoquímicos y interacciones superficie-atmósfera. En últimas décadas se ha aplicado manera creciente el método covarianza flujos turbulentos (EC, por sus siglas en inglés) terrestres, marinos urbanos para medir gases invernadero (p.ej., CO 2 , H O ) energía calor sensible latente).En diversas regiones han establecido redes sistemas EC que aportado...
