- repeated modeling for target area (range + buffer)

 - stepwise change of thresholds

 - (the example shows up to 25 iterations, with offset of 0,5%) per iteration

 - calculation of the Jaccard-Index (J) per iteration

 - formlula:

  - J = C / (A+B+C)

   - C = number of raster cells with 100% climatic agreement or prediction with home range

   - A = number of raster cells of underestimation of home range within the prediction

   - B = number of raster cells of overestimation of home range within the prediction

 - abort, after Jaccard-Index reaching its optimum third time
