Gradient analysis was used to quantify the relationship between plant community structure, prairie dog density, burrow density and habitation history and to document community-level r sponses of plants ubjected to heavy grazing pressure. The results quantify the type, rate and extent of change which plant populations and communities may undergo in response tothe differential grazing of plants variously tolerant of defoliation. Detrended correspondence analysis indicated that 69 % of the between-sample floristic variance on the site was attributable toprairie dog habitation. Perennial grasses were rapidly displaced from the site within 3 yr of colonization and were replaced by annual forbs. The net result was an increase in species richness and diversi-ty ...

These may have direct and indirect effects that could influence management strategies and landscape response to disturbances associated with natural events and land use. The extent to which forecasted global changes are effective in altering local ecosystem properties will depend upon a variety of factors. In this paper, I address species life history traits and community and landscape properties that can be used by land managers to evaluate potential manifestations of global change on a local scale.

Research paper thumbnail of Ecologial Characterization as a Foundation for Prediction of Plains Village Tradition Site Locations in Central South Dakota

North American Archaeologist 3(4): 311-332, 1982

Randomly selected, non-archaeological sites were similarly described and served to define the universe of sites available for habitation along the east bank of the Missouri River/Lake Francis Case Reservoir. Physiographic differences between actual and “simulated” archaeological sites suggested that several factors were important in predicting the location of upland archaeological sites. These included location in the Agropyron smithii dominated plant communities with less than 5° of slope and southern exposure. The model accounts for nearly 70% of all variability associated with location and distribution of archaeological sites.
