I produced current and future distributions using Ensemble.Forecasting, but now I would like to add more realism using the Migration() function and the dispersal parameter MaxMigr. I understand that the MaxMigr units have to be in decimal degrees, but no matter if MaxMigr = 1000 or MaxMigr = 0.16667, the resulting objects (Future20a1b.Migration in my case) are completely identical in terms of probability values.</div>

</div><div><br></div><div>Moreover, when trying to plot the Current, Limited Dispersal and Unlimited Dispersal distributions, the latter 2 look identical (again, regardless of the value given to MaxMigr) </div><div><div>

Also, does the information from Migration feed into the RangeSize function? If so, it is not clear to me how...</div>
