Effects of variation in wolf movement rate on occupancy–abundance relationships.

<p>Occupancy–abundance relationships were estimated from the proportion of survey units in which wolf tracks were detected during simulated aerial surveys as a function of wolf pack density (No. packs/1,000 km²). Wolf movements were based on February (short movements) or December (long movements) step length and turn angle distributions from 2-hour GPS locations from 11 wolves, northeastern Alberta, Canada, 2006–2008. Simulations were run for four grids: (a) 36 km², (b) 144 km², (c) 400 km², and (d) 576 km².
