Abstract We used a nonintrusive field experiment carried out at six sites – Wales (UK), Denmark (DK), the Netherlands (NL), Hungary (HU), Sardinia (Italy IT), and Catalonia (Spain SP) along climatic latitudinal gradient to examine response of plant species richness primary productivity warming drought in shrubland ecosystems. The treatment raised plot daily temperature by ca. 1 °C, while led reduction soil moisture peak growing season that ranged from 26% SP site 82% NL site. During 7 years...
Abstract Globe-LFMC 2.0, an updated version of Globe-LFMC, is a comprehensive dataset over 280,000 Live Fuel Moisture Content (LFMC) measurements. These measurements were gathered through field campaigns conducted in 15 countries spanning 47 years. In contrast to its prior version, 2.0 incorporates 120,000 additional data entries, introduces more than 800 new sampling sites, and comprises LFMC values obtained from samples collected until the calendar year 2023. Each entry within provides...
Measurements of seasonal patterns live fuel moisture content and ignitability (in terms time to ignition) four Mediterranean shrub species were performed in North Western Sardinia (Italy). Relationships between the two variables evaluated. environmental conditions (i.e. rainfall, air temperature soil moisture) analysed. Two groups identified relation different response meteorological conditions. Seasonal also compared with five drought indices: Duff Moisture Code Drought Canadian Forest Fire...
In the last two decades, several models were developed to provide temporal and spatial variations of fire spread behaviour. The most common (i.e. BEHAVE FARSITE) are based on Rothermel's original equation describe behaviour taking into account influences fuels, terrain weather conditions. use FARSITE areas different from those where simulator was originally requires a local calibration produce reliable results. This is particularly true for Mediterranean ecosystems, plant communities...
The objectives of the present study were (i) to describe seasonal pattern ignition delay (ID time) and moisture content live fine fuel (LFMC) for eight common shrub species Western Mediterranean Basin, (ii) evaluate relationships between LFMC ignitability. experiment was carried out in a shrubland area located Sardinia, Italy. time or ID values determined monthly twice month throughout year. Ignitability by laboratory tests. Meteorological data also collected from weather station area....
Abstract Globe-LFMC is an extensive global database of live fuel moisture content (LFMC) measured from 1,383 sampling sites in 11 countries: Argentina, Australia, China, France, Italy, Senegal, Spain, South Africa, Tunisia, United Kingdom and the States America. The contains 161,717 individual records based on situ destructive samples used to measure LFMC, representing amount water plant leaves per unit dry matter. primary goal calibrate validate remote sensing algorithms predict LFMC....
The development of comprehensive fire management and risk assessment strategies is prominent concern in Southern Europe, due to the expanding scale wildfire risk. In this work, we applied simulation modeling analyze fine-scale (100-m resolution) exposure transmission 24,000 km2 island Sardinia (Italy). contains a variety ecological, cultural, anthropic touristic resources that each summer are threatened by wildfires, represents well Mediterranean Basin environments conditions. Wildfire...
In this paper, we applied landscape scale wildfire simulation modeling to explore the spatiotemporal patterns of likelihood and intensity in island Sardinia (Italy). We also performed exposure analysis for selected highly valued resources on identify areas characterized by high risk. observed substantial variation burn probability, fire size, flame length among time periods within season, which starts early June ends late September. Peak probability were July. found that mainly related...
ABSTRACT Aim To test whether the onset of spring growth in European shrublands is advanced response to warmer conditions projected for next two decades by climate models, and, if there a change, it differs across Europe. Location The studied sites spanned broad north–south gradient with average annual temperatures (8.2–15.6 °C) and precipitation (511–1427 mm). Methods ‘Bud break’ was monitored eight shrub grass species six under control experimentally generated automatic roofs covering...
In Mediterranean agropastoral areas, land abandonment is a key driver of wildfire risk as fuel load and continuity increase. To gain insights into the potential impacts on in fire-prone fire-spread modeling approach to evaluate variations induced by different spatial patterns percentages was applied. The study carried out 1200 km2 area located north-western Sardinia (Italy) mostly covered herbaceous fuels. We compared nine scenarios, which consisted control conditions (NA) eight scenarios...
The last IPCC report predicts warmer and drier conditions for the future European climate Mediterranean basin could be highly sensible to climatic change. In order investigate how forecast more stressing factors affect shrubland ecosystems, an appropriate manipulation of microclimate was carried out in area covered by maquis aimed at extending drought period increasing night-time temperature. Soil cover, plant growth, litterfall, leaf water status, nutritional status were monitored over...
Abstract Dust particles lifting and discharge from Africa to Europe is a recurring phenomenon linked air circulation conditions. The possibility that microorganisms are conveyed across distances entails important consequences in terms of biosafety pathogens spread. Using culture independent DNA-based analyses via next generation sequencing the 16 S genes airborne metagenome, atmospheric microbial community was characterized hypothesis tested shifts species diversity could be recorded...
Despite being computationally more efficient than vector-based approaches, the use of raster-based techniques for simulating wildfire spread has been limited by distortions that affect fire shapes. This work presents a Cellular Automata approach is able to mitigate this problem with redefinition velocity, where equations generally used in approaches are modified means number correction factors. A numerical optimization find optimal values The results compared ones given two well-known...
Surface biomass characterization plays a key role in wildfire management. It allows classifying vegetation fuels flammability for fire risk analysis, to define silvicultural prescriptions hazard reduction, plan prescribed burning, or model behavior and its effects, such as greenhouse gas pollutant emissions. To facilitate fuel classification analysis of potential effects Italy, we harmonized 634 measurements surface wildland from Alpine, temperate Mediterranean environments. The dataset...
Wildfires are known to change post-fire watershed conditions such that hillslopes can become prone increased erosion and sediment delivery. In this work, we coupled wildfire spread prediction modelling assess the benefits of fuel reduction treatments in preventing soil runoff. The study was conducted a 68000-ha forest area located Sardinia, Italy. We compared no-treatment v. alternative strategic performed 15% area. Fire behaviour before after estimated by simulating 25000 wildfires for each...
Wildland fires represent a major threat to Quercus suber L. ecosystems, which provide relevant socioeconomic and ecological services in the Mediterranean Basin. In this work, we analyzed recent wildland fire dynamics cork oak woodlands along fire-prone areas of Sardinia (Italy), Corsica (France) Catalonia (Spain). We first characterized geographic extent main characteristics these regions how environmental (climate elevation) factors (population land uses) vary covered by then evaluated...
