GELAM.m runs the simulation both at the state level, and for the Casper example.</p> <p>Location2West.txt contains the data we used in the MATLAB simulations, with the following columns: (1) ID number (FID), (2) number of animals harvested, (3) golden eagle abundance in hunting unit, and (4) size of hunting unit in 100 km² blocks. Information was compiled from publicly available data for Wyoming’s 2012 big game harvest (Wyoming Game and Fish Department 2013, <i>public communication: 2012 annual report of big and trophy game harvest. http://wgfd.wyo.gov/web2011/Departments/Wildlife/pdfs/HR2012_FULLREPORT0005408.pdf accessed 13 May 2014</i>) and preliminary, unpublished estimates of late summer Golden Eagle abundance provided by Ryan Nielson (<i>personal communication</i>, <i>Western EcoSystems Technology, Inc., Cheyenne, WY, February 2014</i>).</p> <p>The eagle density data are from ongoing work that may be revised, using methods reported in two publications: </p> <p>Nielson, R. M. and H. Sawyer. 2013. Estimating resource selection with count data. Ecology and Evolution 3:2233–2240.</p> <p>Neilson, R., L. McManus, T. Rintz, L. L. McDonald, R. K. Murphy, W. H. Howe, and R. E.
