             abstract = "We present preliminary results concerning a central problem in 
                         Ecology with applied implications: to mechanistically predict 
                         animal population abundance and distribution within a real 
                         landscape. We approach it by combining Resource-Area-Dependence 
                         Analysis (RADA) with individual-based modeling (IBM). Common 
                         buzzards Buteo buteo in lowland UK were used to exemplify it. RADA 
                         determined that a buzzard requires, on average, a tree for 
                         roosting, 0.56ha of rough-ground and 15ha of grassland (good 
                         habitats for small mammals). This information was used to define, 
                         in the IBM, virtual animals with realistic resource-related 
                         parameters and their values. Rules concerning maximum foraging 
                         distances and territorial behavior were then included. The model 
                         was run on the 1990 Land Cover Map of Great Britain. Its outputs 
                         were: at the individual-level, home-range area, perimeter and 
                         proportion of overlap (proxy for territoriality), and, at the 
                         population-level, overall range, local density and carrying 
                         capacity of the landscape for buzzards. Virtual buzzards 
                         home-ranges and their pattern of overlap were indistinguishable 
                         from those of wild buzzards. When compared with two independent 
                         field-based estimates, predictions for carrying capacity of 
                         211-226 individuals (100 model runs) suggested buzzards had 
                         recovered from previous low levels and reached equilibrium density 
                         in the area. As our approach relies on remote sensing for data 
                         acquisition, it allows for modeling animals roaming over areas 
                         that are huge, dangerous or difficult to access, and for using 
                         historical and contemporary datasets and techniques. Future 
                         advancements should allow for modeling of social or 
                         non-territorial species, and for considering landscape management 
                         scenarios in a climate change context.",
