Density Estimation--We estimated Sigmodon hispidus population density using abundance (minimum number of individuals known alive) in effective trapping areas, where effective trapping area is equal to the area of a trapping grid plus a boundary strip of half the mean maximum distance moved (MMDM) by recaptured animals (Wilson and Anderson, 1985; Krebs et al.
