Abstract

Plant transpiration links physiological responses of vegetation to water supply and demand with hydrological, energy, and carbon budgets at the land-atmosphere interface. However, despite being the main land evaporative flux at the global scale, transpiration and its response to environmental drivers are currently not well constrained by observations. Here we introduce the first global compilation of whole-plant transpiration data from sap flow measurements (SAPFLUXNET, https://sapfluxnet.creaf.cat/, last access: 8 June 2021). We harmonized and quality-controlled individual datasets supplied by contributors worldwide in a semi-automatic data workflow implemented in the R programming language. Datasets include sub-daily time series of sap flow and hydrometeorological drivers for one or more growing seasons, as well as metadata on the stand characteristics, plant attributes, and technical details of the measurements. SAPFLUXNET contains 202 globally distributed datasets with sap flow time series for 2714 plants, mostly trees, of 174 species. SAPFLUXNET has a broad bioclimatic coverage, with woodland/shrubland and temperate forest biomes especially well represented (80% of the datasets). The measurements cover a wide variety of stand structural characteristics and plant sizes. The datasets encompass the period between 1995 and 2018, with 50% of the datasets being at least 3 years long. Accompanying radiation and vapour pressure deficit data are available for most of the datasets, while on-site soil water content is available for 56% of the datasets. Many datasets contain data for species that make up 90% or more of the total stand basal area, allowing the estimation of stand transpiration in diverse ecological settings. SAPFLUXNET adds to existing plant trait datasets, ecosystem flux networks, and remote sensing products to help increase our understanding of plant water use, plant responses to drought, and ecohydrological processes.

11. New insights into tire-recycling using Micro X-Ray Fluorescence Analysis

Abstract

Synopsis: Recycling of end of life rubber products is a challenging task. One possibility is to re-use ground rubber particles (GRP) as a filler for virgin material. However, this recycled material leads to a reduction of rubber properties in comparison to new compounds. One reason is that sulfur is migrating from the matrix into the GRP, which most likely reduces the crosslink density of the surrounding matrix material. The Micro X-Ray Fluorescence Analysis (µ-XRF) reveals this diffusion effect and illustrates chemical element distributions on a scale of several square centimeters. Additionally, these concentration differences can be quantified with newly developed methods.

Abstract

Forests are major components of the global carbon (C) cycle and thereby strongly influence atmospheric carbon dioxide (CO2) and climate. However, efforts to incorporate forests into climate models and CO2 accounting frameworks have been constrained by a lack of accessible, global-scale synthesis on how C cycling varies across forest types and stand ages. Here, we draw from the Global Forest Carbon Database, ForC, to provide a macroscopic overview of C cycling in the world's forests, giving special attention to stand age-related variation. Specifically, we use 11 923 ForC records for 34 C cycle variables from 865 geographic locations to characterize ensemble C budgets for four broad forest types—tropical broadleaf evergreen, temperate broadleaf, temperate conifer, and boreal. We calculate means and standard deviations for both mature and regrowth (age < 100 years) forests and quantify trends with stand age in regrowth forests for all variables with sufficient data. C cycling rates generally decreased from tropical to temperate to boreal in both mature and regrowth forests, whereas C stocks showed less directional variation. Mature forest net ecosystem production did not differ significantly among biomes. The majority of flux variables, together with most live biomass pools, increased significantly with the logarithm of stand age. As climate change accelerates, understanding and managing the carbon dynamics of forests is critical to forecasting, mitigation, and adaptation. This comprehensive and synthetic global overview of C stocks and fluxes across biomes and stand ages contributes to these efforts.

Abstract

Tree rings provide an invaluable long-term record for understanding how climate and other drivers shape tree growth and forest productivity. However, conventional tree-ring analysis methods were not designed to simultaneously test effects of climate, tree size, and other drivers on individual growth. This has limited the potential to test ecologically relevant hypotheses on tree growth sensitivity to environmental drivers and their interactions with tree size. Here, we develop and apply a new method to simultaneously model nonlinear effects of primary climate drivers, reconstructed tree diameter at breast height (DBH), and calendar year in generalized least squares models that account for the temporal autocorrelation inherent to each individual tree's growth. We analyze data from 3811 trees representing 40 species at 10 globally distributed sites, showing that precipitation, temperature, DBH, and calendar year have additively, and often interactively, influenced annual growth over the past 120 years. Growth responses were predominantly positive to precipitation (usually over ≥3-month seasonal windows) and negative to temperature (usually maximum temperature, over ≤3-month seasonal windows), with concave-down responses in 63% of relationships. Climate sensitivity commonly varied with DBH (45% of cases tested), with larger trees usually more sensitive. Trends in ring width at small DBH were linked to the light environment under which trees established, but basal area or biomass increments consistently reached maxima at intermediate DBH. Accounting for climate and DBH, growth rate declined over time for 92% of species in secondary or disturbed stands, whereas growth trends were mixed in older forests. These trends were largely attributable to stand dynamics as cohorts and stands age, which remain challenging to disentangle from global change drivers. By providing a parsimonious approach for characterizing multiple interacting drivers of tree growth, our method reveals

Abstract

Plant transpiration links physiological responses of vegetation to water supply and demand with hydrological, energy, and carbon budgets at the land-atmosphere interface. However, despite being the main land evaporative flux at the global scale, transpiration and its response to environmental drivers are currently not well constrained by observations. Here we introduce the first global compilation of whole-plant transpiration data from sap flow measurements (SAPFLUXNET, https://sapfluxnet.creaf.cat/, last access: 8 June 2021). We harmonized and quality-controlled individual datasets supplied by contributors worldwide in a semi-automatic data workflow implemented in the R programming language. Datasets include sub-daily time series of sap flow and hydrometeorological drivers for one or more growing seasons, as well as metadata on the stand characteristics, plant attributes, and technical details of the measurements. SAPFLUXNET contains 202 globally distributed datasets with sap flow time series for 2714 plants, mostly trees, of 174 species. SAPFLUXNET has a broad bioclimatic coverage, with woodland/shrubland and temperate forest biomes especially well represented (80% of the datasets). The measurements cover a wide variety of stand structural characteristics and plant sizes. The datasets encompass the period between 1995 and 2018, with 50% of the datasets being at least 3 years long. Accompanying radiation and vapour pressure deficit data are available for most of the datasets, while on-site soil water content is available for 56% of the datasets. Many datasets contain data for species that make up 90% or more of the total stand basal area, allowing the estimation of stand transpiration in diverse ecological settings. SAPFLUXNET adds to existing plant trait datasets, ecosystem flux networks, and remote sensing products to help increase our understanding of plant water use, plant responses to drought, and ecohydrological processes.

Abstract

Allometric equations for calculation of tree aboveground biomass (AGB) form the basis for estimates of forest carbon storage and exchange with the atmosphere. While standard models exist to calculate forest biomass across the tropics, we lack a standardized tool for computing AGB across boreal and temperate regions that comprise the global extratropics. Here we present an integrated R package, allodb, containing systematically selected published allometric equations and proposed functions to compute AGB. The data component of the package is based on 701 woody species identified at 24 large Forest Global Earth Observatory (ForestGEO) forest-dynamics plots representing a wide diversity of extratropical forests. A total of 570 parsed allometric equations to estimate individual tree biomass were retrieved, checked, and combined using a weighting function designed to ensure optimal equation selection over the full tree size range with smooth transitions across equations. The equation dataset can be customized with built-in functions that subset the original dataset and add new equations. Although equations were curated based on a limited set of forest communities and number of species, this resource is appropriate for large portions of the global extratropics and can easily be expanded to cover novel forest types.

Abstract

Introducción: Las opciones terapéuticas en las pacientes con vejiga dolorosa asociada a cistitis intersticial están poco estudiadas. Se pretende verificar la seguridad y eficacia del tratamiento con hialuronato de sodio a través de instilación intravesical en pacientes portadoras de síndrome de vejiga dolorosa. Material y métodos: Se presenta una serie de 18 pacientes femeninas, con edad media de 51 años y diagnóstico previo de síndrome de vejiga dolorosa, que fueron tratadas mediante la infusión de una solución intravesical semanal de 40mg de hialuronato de sodio en solución estéril, durante 8 semanas. Las pacientes fueron evaluadas clínica y urodinámicamente antes de su inclusión en el estudio y 8 meses después de haber finalizado las instilaciones. Resultados: Se observó una mejora estadísticamente significativa en los parámetros urodinámicos y en la sintomatología medida cuantitativamente mediante el cuestionario Pelvic Pain and Urgency/Frequency entre la situación basal y después de la instilación vesical de hialuronato de sodio en paciente con síndrome de vejiga dolorosa. La toxicidad derivada del tratamiento fue nula, puesto que no se registró efecto adverso relacionado con el tratamiento. Conclusión: Se demuestra la utilidad clínica del ácido hialurónico intravesical en pacientes con síndrome de vejiga dolorosa posiblemente asociado a cistitis intersticial. La mejoría clínica se asocia también con aumento de la capacidad y mejora de la sensibilidad vesical. La tolerancia fue excelente. Se necesitan ensayos clínicos que evalúen en profundidad el potencial terapéutico de este fármaco en este tipo de pacientes. Introduction: Few studies have been carried out on therapeutic options in patients with painful bladder syndrome associated with interstitial cystitis. The aim is to verify the safety and effectiveness of treatment with sodium hyaluronate through intravesical instillation in patients with painful bladder syndrome. Materials and methods: A series of 18 female patients is presented, with a mean age of 51 years and prior diagnosis of painful bladder syndrome, who were treated by means of the weekly infusion of an intravesical solution of 40mg of sodium hyaluronate in sterile solution, over a period of eight weeks. The patients were examined clinically and urodynamically prior to their inclusion in the study and eight months after the instillations had concluded. Results: There was a statistically significant improvement in the urodynamic parameters and in the symptoms measured quantitatively by means of the questionnaire "Pelvic Pain and Urgency/Frequency" between the baseline situation and after the vesical instillation of sodium hyaluronate in patients with painful bladder syndrome. There was no toxicity arising from the treatment, given that no adverse effects were recorded in relation to it. Conclusion: The clinical use of intravesical hyaluronic acid in patients with painful bladder syndrome possibly associated with interstitial cystitis has been demonstrated. The clinical improvement is also associated both with increased bladder capacity and improved bladder sensitivity. Tolerance was excellent. Clinical tests that more profoundly evaluate the therapeutic potential of this drug in this type of patients are required.

Abstract

The nucleon-nucleon(NN) bremsstrahlung reaction is studied in the framework of a potential model. We investigate and explain the behavior of the most important corrections to the purely non-relativistic model considering only the external current; i. e. we include the relativistic spin correction, the one-body rescattering contribution and the Coulomb-effect, where it is needed. The important contribution of the two-body or meson-exchange current is treated in the soft-photon-approximation. In addition to the usual coplanar NN$_{\gamma}$ cross section we also study non-coplanar cross sections and spin observables like the analyzing power and spin correlation coefficients. It is shown that the behavior of the relativistic spin correction is governed by the $^{1}$S$_{0}$ partial-wave state, is almost energy independent and reduces the NN$_{\gamma}$ cross section by roughly 20 - 30%. The one-body rescattering contribution enhances the pp$\gamma$ cross section for the geometry of the last TRIUMF experiment by about 20% and thus almost compensates the effect of the relativistic spin corrections. The effects of each part of the NN interaction on the pp$\gamma$ observables is studied in the coplanar geometry. We find that these effects depend on the proton scatteringangles as well as on the considered observable. However, the tensor component of the NN interaction is important in all geometries. The comparison of different NN potential models yields that the NN$_{\gamma}$ reaction is not able to discriminate these potentials in their off-shell behavior, although the corresponding T-matrices deviate from each other off the energy shell. It is concluded that the occuring differences originate already from deviations on the energy shell or from the fact that the approximations made in the calculations for the two-body current are not of the same quality for all NN potential models.
