The usefulness of water quality simulation models for environmental management is explored with a focus on prediction uncertainty. Ecological risk and environmental analysis often involve scientific assessments that are highly uncertain. Still, environmental management decisions are being made, often with the support of a mathematical simulation model. In the area of pollutant transport and fat...

These properties sometimes are crucial ...

This chapter addresses two issues. The first concerns the integration of dynamic and spatial modelling: there are numerous tools available for doing one or the other, but very little for supporting both. The second concerns the flexibility of available tools for representing space: most spatial modelling systems and GIS tend to constrain the user to a limited number of spatial representation fr...

Efforts to relate empirical measurements of population growth dynamical models can be traced back the origins ecology. For example, in his famous study proposing logistic model, Verhulst (1838) presented fitted time-series for human France and Belgium. Interest contrasting data with dynamics has only grown through years (Gilpin, 1973; Powell & Steele, 2012), development sophisticated approaches...

Modelling of economic and ecological impacts of genetically modified crops is a demanding task. We present some preliminary attempts made for the purpose of the ECOGEN project “Soil ecological and economic evaluation of genetically modified crops”. One of the goals of the project is to develop a computer-based decision support system for the assessment of economic and ecological impacts of usin...

The main goal of this study was to predict, through the use of GIS tool as ecological niche modelling, potentially suitable ecological niche and defining the conditions of such niche for the representatives of the cosmopolitan genus Sirthenea. Among all known genera of the subfamily Peiratinae, only Sirthenea occurs on almost all continents and zoogeographical regions. Our research was based on...

Abstract Recent extreme wildfire seasons in several regions have been associated with exceptionally hot, dry conditions, made more probable by climate change. Much research has focused on fire weather and its drivers, but natural regimes—and their interactions human activities—are far from being comprehensively understood. There is a lack of clarity about the ‘causes’ wildfire, how ecosystems c...
