Cultural Evolutionary

Native American communities occupying the western Great Plains during the postcontact period exemplify the highly contingent relationships between artifactual data and cultural processes. Here, cultural evolutionary theory and quantitative analyses are used to approach this challenge. Two sets of artif actual products were examined: parfleche attributes and moccasin decorative features, both products of female craftswomen.A model of “isolation by distance “ drawn from population genetics is used as a baseline expectation. This model predicts that, all else being equal, between-group geographic relationships will correlate with intergroup patterns of artif actual variation. Linguistic affinity and known patterns of intertribe alliance and hostility were also examined. The analyses reveal the operation of differing degrees of social transmission and differing patterns of selective bias in each artif actual case. In the case of parfleches, their potential to act as visible signals led to a patterned distribution reflecting intertribe alliance and hostility. The analyses reiterate the necessity of a cultural evolutionary approach to material culture, not only because this method facilitates the requisite flexibility toward particular historical trajectories of artifactual lineages, but also because evolutionary principles provide a range of theoretical models and practical tools of analysis, which facilitate an empirical and quantitatively analytical approach to this problem.

Wheat is an important food grain worldwide and the primary dryland crop in the western Great Plains. A complex of three wheat curl mite (WCM)-transmitted viruses (Wheat streak mosaic virus, High plains virus, and Triticum mosaic virus [TriMV]) is a cause of serious loss in winter wheat production in the Great Plains. TriMV was first reported in Kansas in 2006 and later found in most other Great Plains states. Currently, three populations of WCM have been identified by genetic characterization and differential responses to mite resistance genes in wheat. In this study, we examined TriMV transmission by these three WCM populations: ‘Nebraska’ (NE), ‘Montana’ (MT), and ‘South Dakota’ (SD). Mite transmission using single-mite transfers revealed that the NE WCM population transmitted TriMV at 41%, while the MT and SD WCM populations failed to transmit TriMV. In multi-mite transfers, the NE WCM population transmitted TriMV at 100% level compared with 2.5% transmission by MT and SD WCM populations. Interestingly, NE mites transferred during the quiescent stages following the first and second instar transmitted TriMV at a 39 to 40% rate, suggesting that immature mites were able to acquire the virus and maintain it through molting. In addition, mite survival for single-mite transfers was significantly lower for NE mites when transferred from TriMV-inoculated source plants (60%) compared with mock-inoculated source plants (84%). This demonstrates potentially negative effects on WCM survival from TriMV. TriMV transmission differences demonstrated in this study underscore the importance of identification of mite genotypes for future studies with TriMV.
