| FIGURE 2. Visitation frequencies of mammals at three distance intervals from a forested edge in fragments of native tallgrass prairie in southwestern Missouri, 1996-1997. Data are shown separately for all mammals combined, mid-sized carnivores, and small mammals. Least squares means and their standard errors are shown to control for confounding variation due to fragment size. |
