Abstract. Plant transpiration links physiological responses of vegetation to water supply and demand with hydrological, energy, carbon budgets at the land–atmosphere interface. However, despite being main land evaporative flux global scale, its response environmental drivers are currently not well constrained by observations. Here we introduce first compilation whole-plant data from sap flow measurements (SAPFLUXNET, https://sapfluxnet.creaf.cat/, last access: 8 June 2021). We harmonized...
Abstract. Globally, coffee has become one of the most sensitive commercial crops, being affected by climate change. Arabica (Coffea arabica) grows in traditionally shaded agroforestry systems tropical regions and accounts for ∼70 % production worldwide. Nevertheless, interaction between plant soil water sources these plantations remains poorly understood. To investigate functional response dominant shade tree species (C. arabica var. typica) plants to different availability conditions, we...

The provision and regulation of water flows in catchments is probably the most important ecosystem service cloud forests; however, its hydrological behavior impacts associated with forest conversion remain very poorly understood.The present study aimed at evaluating effects land use change for a region on volcanic soils Veracruz, Mexico.For this, micrometeorological, ecophysiological measurements combined stable isotope data were used.The findings showed higher annual yields pasture, as well...
Abstract Coastal settings variations are linked to composition, structural, and functional differences among mangrove ecotypes. Basin mangroves undergo larger flooding salinity fluctuations, yet remain understudied, compared other We evaluated the effect of air temperature ( T a ) on surface energy balance eddy covariance‐derived net CO 2 ecosystem exchange (NEE) basin with sporadic freshwater flooding. During study period (June 2017–November 2018) site was more frequently not flooded. Under...
Abstract Carbon storage values in the Amazon basin have been studied through different approaches last decades order to clarify whether rainforest ecosystem is likely act as a sink or source for carbon near future. This water balance, dissolved organic (DOC) and nutrient export study were carried out micro‐scale heath forest ( Campina ) catchment central Amazonia, Brazil. For 1‐year period (18 March 2007 until 19 2008), rainfall amounted 3054 mm; of which, 1532 mm was evaporated by (4.1 day...
Background Land use is a major factor determining stream water physicochemistry. However, most streams move from one land type to another as they drain their watersheds. Here, we studied three scenarios in tropical cloud forest zone Mexico. We addressed main goals, to: (1) assess how generate different patterns physicochemical characteristics; (2) explore seasonality ( i.e ., dry, dry-to-wet transition, and wet seasons) might result changes those over the year; (3) whether resulted effects...
Land surface evapotranspiration (ET) data is required accurately and in near-real time for operational applications such as regional drought monitoring. Satellitederived ET products are promising this purpose, particularly poorly gauged areas south-eastern Mexico. Products (and algorithms) MODIS Global Evaporation Project (MOD16) readily publicly available but require evaluation prior to its local application. Here, we present a comparison of MOD16 annual potential (PETMOD) with that...
This paper presents a containerized service for clustering and categorization of weather records in the cloud. considers scheme microservices containers organizations end-users to manage/process from acquisition, passing through prepossessing processing stages, exhibition results. In this service, specialized crawler acquires that are delivered microservice distributed records, which performs acquired data (the temperature precipitation) by spatiotemporal parameters. The clusters found...
Los manglares son ecosistemas costeros estratégicos frente al cambio climático, pero aún existen vacíos de conocimiento sobre la dinámica del gran reservorio carbono que contienen. Se presenta un análisis cienciométrico el ciclo en manglares, con especial interés los flujos CO2 y CH4. El término “carbono azul” es actualmente distintivo literatura científica, sobresaliendo como palabra clave publicaciones 380 revistas. La geografía dicha revisión muestra mayoría las presentan resultados...
Knowledge of temporal variations in radial profiles sap flux density (J s ) and its relation to canopy water vapour exchange would help improve our understanding plant relations.In this study we aimed test if there is a consistent profile J olive trees under optimal soil availability severe stress conditions.Furthermore, the not through time assess whether variability can be explained differential response evaporative demand (D) sun-exposed, new foliage shade, old foliage.We measured trunk...
The relative importance of allochthonous and autochthonous carbon (C) as sources energy for tropical stream food webs remains an open question. Allochthonous C might be the main source small shaded forest streams, while is more likely to fuel draining land uses with less dense vegetation. We studied in cloud streams watersheds forests, coffee plantations, pastures. Our goal was assess effects those on structure webs. study took place montane La Antigua Watershed, eastern Mexico. selected...
This paper presents Kawak, a GIS-bigdata model for merging retrospective meteorological data with ground-based observations to achieve comprehensive territorial coverage. identifies areas without active stations and creates virtual these areas. Kawak incorporates AI algorithms conducting spatio-temporal studies, enabling seamless exploration of climate patterns. We implemented in prototype conducted an exploratory case study by fusing temperature records from MERRA-2 EMAS Mexico over 33...
Abstract Sap flow measurements are fundamental to understanding water use in trees and could aid predicting climate change effects on forest function. Deriving knowledge from such requires empirical calibrations upscaling methods translate thermometric recordings tree use. Here, we developed a user‐friendly open‐source application, the Flow Analyzer (SFA), which estimates sap rates heat field deformation (HFD) instruments. The SFA incorporates four key features ensure maximum accuracy...
Rehabilitating flooding dynamics and modifying soil elevation to achieve mangrove restoration has become increasingly common, but their effects on hydroperiod characteristics have yet be studied. This study assessed how microtopography influences the inundation regime, chemical properties, seedling growth in a restored at Tampamachoco Lagoon Gulf of Mexico. Water flow disruption affected about 352 ha this ecosystem, resulting level collapse. Restoration efforts involved construction 0.3-0.4...
