Ungulate Ecology,tality, population growth and structure, and resource availability (Andrewarth 1961; Moss . 1982), anthropologists use the term . to refer almost exclusively to seasonal differences in herd sizes and movement patterns. In addition, Reher and Frison (1980) stress another important aspect of bison ecology, the density of animals in an area.

Patterns of Forage Production on the Great Plains, adaptations there. As Chapter 4 shows, patterns of forage production are the most important of these determinants, and forage production is largely controlled in turn by climatic factors. This chapter therefore considers the differences in modern climate across the Plains and demonstrates the effect of these differences on forage production.

Resource Structure and Human Organization,ines a basis for evaluating, first, important characteristics of the resources available in a region and, second, the degree of human social complexity there. Given this outline, it then discusses a general relationship between resources and complexity, with a specific emphasis on the Great Plains.

The major subjects of this chapter are the effects of climate, soils, and grazing on the amount and quality of forage a grassland can produce.
