Evidence for Edge Effects on Multiple Levels in Tallgrass Prairie


FIGURE 1.  Frequency of (a) nest survival of artificial nests and (b) predation of artificial nests by mid-sized carnivores, at three distance intervals from a forested edge in southwestern Missouri prairie fragments, 1995. Bars indicate standard errors.


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.
