ABSTRACT Sediment transport during flood events often reveals hysteretic patterns because flow discharge can peak before (counterclockwise hysteresis) or after (clockwise the of bedload. Hysteresis in sediment has been used literature to infer degree availability. Counterclockwise and clockwise hysteresis have fact interpreted as limited unlimited supply conditions, respectively. mainly explored for case suspended transport, but it was rarely reported bedload mountain streams. This work...
Abstract To understand how diversity is distributed in space a fundamental aim for optimizing future species and community conservation. We examined parallel richness beta components of nine taxonomic groups along finite space, represented by pastured grasslands an elevational gradient. Beta diversity, which assumed to bridge local alpha regional gamma was partitioned into the two turnover nestedness analyzed at levels: from lowest elevation all other elevations, between neighboring...
A synergic integration of Synthetic Aperture Radar (SAR) and optical time series offers an unprecedented opportunity in vegetation phenology monitoring for mountain agriculture management. In this paper, we performed a correlation analysis radar signal to soil conditions by using Sentinel-1 C-band dual-polarized (VV VH) SAR images acquired the South Tyrol region (Italy) from October 2014 September 2016. Together with images, exploited corresponding Sentinel-2 ground measurements. Results...
Abstract Background and aims A better understanding of plant carbon assimilation, water status photosystem performance responses to combined heat drought stress would help optimize grapevine management under such limiting conditions. Methods Gas exchange chlorophyll fluorescence parameters were measured in potted grapevines, cv Sauvignon Blanc, before, during after simulated six-day (T max = 40 °C) wave using heated well-watered (HW), drought-stressed (HD), non-heated (CW) dry (CD) vines....
This paper presents an approach for retrieval of soil moisture content (SMC) from different satellite sensors with a focus on mountain areas. The novelties the are: extension already developed method to coarse resolution data (150 m) in environment high land heterogeneity, only VV polarization and proper selection input features. During result analysis, several algorithm characteristics were clearly identified: 1) performances showed be strongly related features such as topography vegetation...
In complex, sloping terrain, horizontal measurements of net radiation are not reflective the radiative energy available for conductive and convective heat exchange underlying surface. Using data from a grassland site on mountain slope characterised by spatial heterogeneity in inclination aspect, we tested hypothesis that correction which accounts individual footprint contributions various surfaces to measured sensible latent eddy covariance fluxes will yield more realistic slope-parallel...
Lower atmospheric pressure affects biologically relevant physical parameters such as gas partial and concentration, leading to increased water vapor diffusivity greater soil content loss through evapotranspiration. This might impact plant photosynthetic activity, resource allocation, relations, growth. However, the direct of low air on physiology is largely unknown. study examined effects pressure, alone combined with two inputs, different functional traits three species transplanted from...
ABSTRACT The effects of elevation on surface water fluxes in dry alpine grassland ecosystems were investigated along an elevational transect between 1000 and 2000 m above sea level established the Vinschgau/Venosta valley, a relatively region Italian Alps. GEOtop‐dv hydrological model was employed point‐scale mode to gradient snow equivalent ( SWE ), soil content θ evapotranspiration ET aboveground biomass B ag ) use efficiency WUE different climatic conditions.

In this work, the polarimetric capability of RADARSAT-2 images is exploited in aim soil moisture content retrieval Alpine meadows and pastures. Three feature extraction methods are investigated: simple intensity phase processing, H/A/α decomposition, Independent Component Analysis (ICA). The features extracted according to these strategies were assessed for their improve estimation by considering both quantitative performance on a set reference samples qualitative analysis corresponding...
Grasslands cover up to 40% of the mountain areas globally and 23% European Alps affect numerous key ecological processes. An increasing number optical sensors offer a great opportunity monitor address dynamic changes in growth status grassland vegetation due climatic anthropogenic influences. Vegetation indices (VI) calculated from sensor data are powerful tool analyzing dynamics. However, different have their own characteristics, advantages, challenges monitoring over space time that...
Soil moisture retrieval is one of the most challenging problems in context biophysical parameter estimation from remotely sensed data. Typically, microwave signals are used thanks to their sensitivity variations water content soil. However, especially Alps, presence vegetation and heterogeneity topography may significantly affect signal, thus increasing complexity retrieval. In this paper, effectiveness RADARSAT2 SAR images for soil an alpine catchment investigated. We first carry out a...
Detailed knowledge of agricultural soil properties is a key element for high-quality food production. However, high-resolution data covering large region are generally unavailable. This study explores demand-driven cooperative framework sourcing that connects individual farmers to several stakeholders by means centralised database containing more than 16,000 records information collected within the an integrated production program intensively managed permanent crops in Adige/Etsch and...
Summary This paper presents the results of a two‐year experiment carried out in mountain areas on soil moisture retrieval from remotely sensed images. In particular, fully polarimetric synthetic aperture radar ( SAR ) RADARSAT and single polarization ASAR images were used. During acquisitions over test area Alto Adige, Südtirol region, n orthern Italy, extensive field measurements to characterize terms variability, vegetation cover properties.
