(Thick Black Line) Estimate of N
from equation (2). (Dashed Thin Lines) Census population in domain. The squares (□) are for a domain 1024 km in size, the circles (○) are for a domain 4096 km in size, and the diamonds (◇) for a domain 16384 km in size. (Solid Lines) Estimates of Ne from a numerical model with varying Ladv and a constant Ldiff of 200 km. For the purposes of simulation, the carrying capacity of the domain is about 0.5 individuals per kilometer.
