             abstract = "An animal's home-range can be expected to encompass the resources 
                         it requires for surviving or reproducing. Thus, animals inhabiting 
                         a heterogeneous landscape, where resource patches vary in size, 
                         shape and distribution, will naturally have home-ranges of varied 
                         sizes, so that each home-range encompasses a minimum required 
                         amount of a resource. Homerange size can be estimated from 
                         telemetry data, and often key resources, or proxies for them such 
                         as the areas of important habitat types, can be mapped. We propose 
                         a new method, Resource-Area-Dependence Analysis (RADA), which uses 
                         a sample of tracked animals and a categorical map to i) infer in 
                         which map categories important resources are accessible, ii) 
                         within which home range cores they are found, and iii) estimate 
                         the mean minimum areas of these map categories required for such 
                         resource provision. We provide three examples of applying RADA to 
                         datasets of radio-tracked animals from southern England: 15 red 
                         squirrels Sciurus vulgaris, 17 gray squirrels S. carolinensis and 
                         114 common buzzards Buteo buteo. The analyses showed that each red 
                         squirrel required a mean (95% CL) of 0.48 ha (0.24-0.97) of pine 
                         wood within the outermost home-range, each gray squirrel needed 
                         0.34 ha (0.11-1.12) ha of mature deciduous woodland and 
                         0.035-0.046 ha of wheat, also within the outermost home-range, 
                         while each buzzard required 0.54 ha (0.35-0.82) of rough ground 
                         close to the home-range center and 14 ha (11-17) of meadow within 
                         an intermediate core, with 52% of them also relying on 0.41 ha 
                         (0.29-0.59) of suburban land near the homerange center. RADA thus 
                         provides a useful tool to infer key animal resource requirements 
                         during studies of animal movement and habitat use.",
