Although such models can be extended to model the geographic spread of infectious diseases on patches [7], when it is not clear which spatial scales are most important, it is difficult to use compartmental approaches with confidence.
Finally, the geographic coordinates of each county were taken as the geometric centre of the county and were used to model the geographic variations of incidence and mortality.
We modelled the geographic distributions of 435 endemic plants and all 347 endemic vertebrate species, from existing museum and herbaria specimens at a regional conservation practitioner's scale (1 250,000-1 1,000,000), based on the best available tools and geographic data.
With 15 recognized subspecies [ 20] and genetically structured populations, P. polionotus is an excellent model species for developing new methods of data partitioning to overcome the problems associated with modeling the geographic distributions of widely distributed species.
To model the geographic distribution of the generated requests, the set includes an occurrence counter for each location, which then can assign locations to created requests via roulette wheel.
To represent a diverse suite of species, we modelled the geographic distributions of all bird, mammal, and amphibian species that are endemic to our study area [ 7- 9] (Table 1).
We used a database of anthrax outbreak locations in Kazakhstan and a subset of genotyped isolates to model the geographic distribution and ecological associations of B. anthracis in Kazakhstan.
For this study, we modeled the current geographic distribution of B. anthracis using three different scenarios at two different resolutions.
The presence-only ENM approach has been successfully employed to model the potential geographic distribution of a number of taxa [17] [21], including disease vectors [22] [27] and disease organisms [8], [28].
Another study from Kazakhstan also used GARP to model the potential geographic distribution of environments that likely support long-term persistence of B. anthracis and confirmed that repeat livestock anthrax epizootics occur within that predicted geographic range of the organism (Aikembayev unpublished manuscript).
