For more than five decades, research has been conducted at Ny-Ålesund, in Svalbard, Norway, to understand the structure and functioning of High-Arctic ecosystems profound impacts on them environmental change. Terrestrial, freshwater, glacial marine are accessible year-round from providing unique opportunities for interdisciplinary observational experimental studies along physical, chemical, hydrological climatic gradients. Here, we synthesize terrestrial freshwater Ny-Ålesund review current...
The satellite monitoring of vegetation moisture content (VMC) and soil (SMC) in Southern European Atlantic mountains remains poorly understood but is a fundamental tool to better manage landscape dynamics under climate change. In the humid Portugal, we investigated an empirical model incorporating (Sentinel-1 radar, S1; Sentinel-2 optical, S2) ancillary predictors (topography cover type) monitor VMC (%) SMC (%). Predictors derived from S1 (VV, HH VV/HH) S2 (NDVI NDMI) are compared field...
Abstract Enhancing the capacity of social‐ecological systems (SES) to adapt climate change is crucial importance. While gradual impacts have been main focus much recent research, less known about how SES are impacted by extremes and they adapt. Here, based on an advanced conceptualization resilience, performed interdisciplinary group scientists, we outline three major challenges for operationalizing resilience concept with particular extremes. First, discuss necessary steps required identify...
Non-steady-state closed dynamic accumulation chambers are widely used to measure the respiration of terrestrial ecosystems, thanks their low cost, energy consumption and simple transportability, that allow measurements even in hostile remote environments. However, assessment accuracy precision associated with measurement system (independently possible disturbances due chamber-soil interactions) is rarely reported. This information instead necessary for basic quality control, compare data...
High-Arctic ecosystems are strongly affected by climate change, and it is still unclear whether they will become a carbon source or sink in the next few decades. In turn, such knowledge gaps on drivers processes controlling CO2 fluxes storage make future projections of Arctic budget challenging goal. During summer 2019, we extensively measured at soil-vegetation-atmosphere interface, together with basic meteoclimatic variables ecological characteristics Bayelva river basin near Ny Ålesund,...
The dynamics of carbon dioxide fluxes in the high-altitude Alpine Critical Zone is only partially understood. complex geomorphology induces significant spatial heterogeneity, and a strong interannual variability present often-extreme climatic environmental conditions ecosystems. To explore relative importance temporal CO2 fluxes, we analysed set in-situ measurements obtained during summers from 2018 to 2021 four sampling plots, characterised by soils with different underlying bedrock within...
We introduce a georeferenced dataset of Net Ecosystem Exchange (NEE), Respiration (ER) and meteo-climatic variables (air soil temperature, air relative humidity, volumetric water content, pressure, solar irradiance) collected at the Nivolet Plain in Gran Paradiso National Park (GPNP), western Italian Alps, from 2017 to 2023. NEE ER are derived by measuring temporal variation CO
Mountain ecosystems are particularly sensitive to the effects of climate change and require a detailed understanding how their components respond varying environmental conditions. However, knowledge crucial biogeochemical variables, such as carbon dioxide (CO2) fluxes in Critical Zone high-altitude grassland Alpine tundra, is still patchy. In this framework, two methods typically adopted measure CO2 exchanges between atmosphere underlying ecosystem: eddy covariance accumulation chambers....
Conservation and policy agendas, such as the European Biodiversity strategy, Aichi biodiversity (target 5) Common Agriculture Policy (CAP), are overlooking progress made in mountain grassland cover conservation by 2020, which has significant socio-ecological implications to Europe. However, because existing data near 2020 is scarce, shifting character of grasslands remains poorly characterized, even less known about outcomes different governance regimes map uncertainty. Our study used...
Abstract. Gross primary productivity (GPP) is a crucial variable for ecosystem dynamics, and it can significantly vary on the small spatial scales of vegetation environmental heterogeneity. This especially true mountain ecosystems, which pose severe difficulties to field monitoring. In addition, specificity such ecosystems extreme abiotic conditions that they experience often make global regional models unsuited predictions. this case, remote sensing products offer opportunity explore...
Svalbard (Norway) is a "hotspot" of climate change. There, various research activities are taking place, most them located at the Ny-Ålesund Research Station, on shore Kingsfiord, mainly focused understanding change dynamics and its effects Arctic marine terrestrial ecosystems, including their interconnections. In fact, fiord unique environment where atmosphere, sea, land ecosystems strictly connected. Among other ones, Ny Ålesund hosts Italian Station "Dirigibile Italia", multidisciplinary...
