Abstract: | This paper puts forth a non-linear, post-structural conception of geographical diffusion by utilizing the example of American bison. In doing so, this approach stands in contrast to canonical theories of diffusion (notably neoclassical economics and political economy), which portray diffusion as a steady progression of development. In reviewing the history of bison diffusion during the 20th century, the impact of several factors is evident. These include environmental, cultural, economic, governmental, health and material factors. Each of these variables has taken several distinct forms, thereby enlarging the number of actors involved in the species’ redistribution. The impact of each variable has waxed and waned over the years. Consequently, a series of heterogeneous networks has formed, which have simultaneously undercut the importance of certain variables and formed the basis for new channels of bison diffusion. The non-linear nature of diffusion emerges from the different temporalities of these networks. In an alternating fashion, this process of network-building has guided bison onto public, private, and tribal lands. |
