Parameter sets used for the simulations of the late Pleistocene dispersal in the Americas.

K is the carrying capacity of every cell. Ntot is the total number of individuals in the Americas at the end of the corresponding simulation. For all parameter sets, the resulting growth rate is 0.06/yr, the diffusion coefficient is D ∼ 180 km2/yr, and the deterministic speed is vdet ∼ 6.57km/yr. Δx is the distance between two neighboring nodes, i.e., the spatial resolution.K为每个单元格的环境容纳量（carrying capacity）。Ntot为对应模拟结束时美洲地区的个体总数量。针对所有参数集，所得增长率为0.06/年，扩散系数D≈180 km²/年，确定性传播速度vdet≈6.57 km/年。Δx为相邻两个节点间的距离，即空间分辨率。
