Abstract The wildland-urban interface (WUI) is the spatial manifestation of human communities coupled with vegetated ecosystems. Spatial delineation WUI important for wildfire policy and management, but typically defined according to relationships between housing development wildland vegetation without explicit consideration fire risk. A risk-based definition can enable a better distribution management investment so as maximize social return. We present novel methodological approach...
Abstract Distinguishing between natural forests from exotic tree plantations is essential to get an accurate picture of the world’s state forests. Most support lower levels biodiversity and have less potential for ecosystem services supply than forests, differencing them still a challenge using standard tools. We use novel approach in south-central Chile differentiate cover dynamics among plantations. has one most competitive forestry industry region global hotspot. Our collaborative visual...
To determine whether the treatment with oseltamivir improves outcome of children confirmed influenza infection and no other underlying disease.Multicentric, retrospective study performed in 10 hospitals Madrid between September 2010 June 2012. All admitted to infections were eligible. Children risk factors for serious disease nosocomial excluded. Asthma was not considered an exclusion factor. The compared patients treated untreated oseltamivir. Fever duration, oxygen support, antibiotics...
Cell2Fire is a new cell-based wildland fire growth simulator designed to integrate data-driven landscape management planning models. The environment modeled by partitioning the into cells characterized fuel, weather, moisture content, and topographic attributes. model can use existing spread models such as Canadian Forest Fire Behavior Prediction System growth. structured facilitate its for predicting of individual fires or embedding it in simulation Decision-making fuel treatment/harvesting...
The use of fire simulation tools has become a regular feature support systems for fuel management decisions at landscape level. Considering the spatial nature in evaluation risk and definition mitigation goals is an ongoing research topic forest planning. By combining tool, growth yield simulator optimization module, it possible to minimize negative impact over time maximize various ecosystem services. Specific requirements adapted tactical planning include level accuracy, possibility...
Monitoring wildfires is an essential step in minimizing their impact on the planet, understanding many negative environmental, economic, and social consequences. Recent advances remote sensing technology combined with increasing application of artificial intelligence methods have improved real-time, high-resolution fire monitoring. This study explores two proposed approaches based U-Net model for automating optimizing burned-area mapping process. Denoted 128 AllSizes (AS), they are trained...
In practical applications, it is common that wildfire simulators do not correctly predict the evolution of fire scar. Usually, this caused due to multiple factors including inaccuracy in input data such as land cover classification, moisture, improperly represented local winds, cumulative errors growth simulation model, high level discontinuity/heterogeneity within landscape, among many others. Therefore practice, necessary adjust propagation obtain better results, either support suppression...
Abstract Ecosystem collapse in direct response to climate change is a critical but poorly documented phenomenon. By assessing the context and productivity trends Mediterranean ecosystems worldwide, we found large-scale, abrupt forest decline Chile (>90% <100 days) as sustained, acute drought unprecedented recent history of Mediterranean-type ecosystems. These extreme conditions were projected for 2070-2090, suggesting that impacts are accelerating.

<title>Abstract</title> Bat boxes are a key element in bat conservation policies being very popular. However, it is biased action that only favourable for few species. In this manuscript, we hypothesize the installation of these elements and an extensive proliferation them could threaten other species more vulnerable due to niche competition. For this, calculated overlapping degree between use those do not, specifically: 1) To determine favourability area through habitat suitability models...
Over the past decades, increase in both frequency and intensity of large-scale wildfires due to climate change has emerged as a significant natural threat. The pressing need design resilient landscapes capable withstanding such disasters become paramount, requiring development advanced decision-support tools. Existing methodologies, including Mixed Integer Programming, Stochastic Optimization, Network Theory, have proven effective but are hindered by computational demands, limiting their...
Cell2Fire is a new cell-based forest and wildland landscape fire growth simulator that open-source exploits parallelism to support the modelling of cross large spatial temporal scales in timely manner. The environment characterized by partitioning into number cells each which has specified fuel, weather, fuel moisture topography attributes. Fire spread within cell assumed be elliptical governed rates predicted model such as Canadian Forest Behavior Prediction (FBP) System. includes powerful...
This paper presents an open-source computational tool that simulates the growth of fires which may occur in any region Chile, and is also capable estimating burn probability maps through iterative concatenated process simulating spatially explicit fire ignition scenarios. tool, known as C2F+K, based on Cell2Fire simulator KITRAL, Chilean behaviour system. It incorporates new equations for calculation rate spread length-to-breadth ratio a function wind speed are elliptical shape model. C2F+K...
Abstract Traditional Species Distribution Models (SDMs) may not be appropriate when examples of one class (e.g. absence or pseudo-absences) greatly outnumber the other presences observations), because they tend to favor learning observations more frequently. We present an ensemble method called R andom U nder S ampling and Boost ing (RUSBoost), which was designed address case where number presence records are imbalanced, we opened “black-box” algorithm interpret its results applicability in...
One way to mitigate the uncontrolled effect of fires and, at same time, protect our communities and ecological values, is through forest fuel management. Theses activities constitute a means fire prevention, involving planned changes living or dead wildland fuels (prescribed burning, pruning, firebreaks, etc.) in order lessen behaviour potential. In this study, we propose an integrated optimization simulation approach locate firebreaks on landscape, so that damage resulting from removal...
The problem of firebreak placement is crucial for fire prevention, and its effectiveness at landscape scale will depend on their ability to impede the progress future wildfires. To provide an adequate response, it therefore necessary consider stochastic nature fires, which are highly unpredictable from ignition extinction. Thus, firebreaks can be considered a optimization where: (1) objective function minimize expected cells burnt landscape; (2) decision variables being location firebreaks;...
&lt;p&gt;The Wildland-Urban Interface (WUI) is the spatial manifestation of coupling human communities and ecosystems, wildfire most prominent issue. The WUI accounts for large percentages fire prevention suppression expenditures because it where fatalities structure losses occur. Therefore a fire-risk based definition delimitation may be critical to properly distributing action management investments obtain maximum social return. We present first methodological approach that can...
