Wood biophysical properties and the dynamics of water storage discharge refilling were studied in trunk canopy tree species with diverse life history functional traits subtropical forests northeast Argentina. Multiple techniques assessing capacitance capacity used simultaneously to improve our understanding significance internal sources trunks large trees. Sapwood capacitances 10 characterized using pressure–volume relationships sapwood samples obtained from trunk. Frequency domain...
The canopy photosynthesis and carbon balance of the subtropical forests are not well studied compared to temperate tropical forest ecosystems. main objective this study was assess seasonal dynamics Normalized Difference Vegetation Index (NDVI) potential in relation changes leaf area index (LAI), chlorophyll concentration, air temperatures NE Argentina throughout year. We included analysis several tree plantations (Pinus, Eucalyptus Araucaria species) that known have high productivity. Field...
Abstract Grazing is the predominant land use practice in arid environments; however, there are relatively few studies of grazing effects on ecosystem functioning. We assessed impact soil moisture, evapotranspiration (ET), canopy conductance (G c ), and root water uptake Patagonian steppe. Studies were done 3 sites along a gradient intensity. High intensity increased storage by 24% decreased amount extracted from deep layers compared to low affected ET its partitioning into transpiration (T)...
Abstract The fraction of intercepted photosynthetic active radiation (fPAR) is a key variable used by the Monteith model to estimate net primary productivity (NPP). This can be assessed vegetation indices (VIs) derived from spectral remote sensing data but several factors usually affect their relationship. objectives this work were analyse fPAR dynamics and describe relationships between (normalized difference index (NDVI), optimized soil adjusted (OSAVI), Green NDVI (GNDVI), visible...
Afforestation has been proposed as an effective tool for protecting primary and/or secondary forests and mitigating atmospheric CO2. However, the dynamics of productivity differs between plantations natural forests. The objective this work was to evaluate potential carbon storage a commercial pine plantation by determining its balance. Measurements started when trees were aged 6 ended they older than 8 years. We measured CO2 water vapor concentrations using Eddy covariance method. Gross in...
Abstract Absorbed solar radiation and use efficiency ( RUE ) can be used to estimate net primary productivity of terrestrial ecosystems. In ecosystems dominated by grasses, belowground cannot neglected in terms carbon balance because the high proportion biomass allocated roots. The objective this study was quantify total tRUE ), which includes both below aboveground two C 3 L olium perenne D actylis glomerata one 4 ynodon dactylon grass species, under four treatments with contrasting water...
Abstract The radiation use efficiency (RUE) model is one of the most used tools to generate large spatial and temporal scale net primary productivity (NPP) estimations by remote sensing. It involves two key issues make accurate NPP: estimation fraction photosynthetically active (PAR) intercepted vegetation (fPAR) plant RUE. objectives this work were quantify above‐ground RUE under optimal water nutrient conditions in C 3 4 grass species analyse effect restrictions these factors upon...
Wood density (WD) and other wood mechanical structural properties may have a strong functional relationship with demographic patterns allometry of trees. We analyzed the influence WD, properties, architectural traits, community-level attributes on growth rates (GRs) mortality modes canopy tree species in subtropical forest Argentina. Stem WD strength, stiffness, toughness, hardness branches were measured 10 species. Architectural traits liana load also determined. Strength linearly...
Accurate estimates of seasonal evapotranspiration (ET) at different temporal and spatial scales are essential for understanding the biological environmental determinants ecosystem water balance in arid regions patterns utilization by vegetation. For this purpose, remote sensing ET a Patagonian desert Southern Argentina were verified with field measurements soil evaporation plant transpiration using an open top chamber. Root distribution variation volumetric content also analysed. There was...

The talares represent the main native forest of Buenos Aires province; however, they are in danger. Given their extreme vulnerability, it is not only necessary to promote conservation, but also restoration. plant nurseries a key link restoration projects. In this work, first survey distribution area was carried out characterize and evaluate them as possible nodes. During 2019, surveys these were either person or online. More than 70% concentrated Metropolitan Area objectives comprise...
The Argentine Native Plant Nursery Network (REVINA) links different social actors involved in native plant production, their valorization and the restoration of Argentina’s ecosystems. It is essential to strengthen network order meet country’s goals, considering that nursery community will generate species be primary inputs for projects. In this paper we study network, plants they produce, projects Argentina through survey participants annual meetings REVINA period 2016-2020. We observed has...
