Anthropological Knowledge and Native American Cultural Practice in the Liberal Polity

U.S. Indian policy is caught between two incommensurable theories or paradigms. First, liberal theory extended the worldviewof early physical science to understand human nature. Providing the conceptual foundation for liberal polities, it largely underwrote U.S. Indian policy into the mid-20th century. Liberal theory recently has been superceded, as theory , by anthropological culture theory, which better accounts for variations between peoples and the realities of human life. The advent of culture theory marks a major paradigm shift within science and public consciousness. Liberal theory, however, remains the foundation for the powerful ideology of liberalism and the institutional practices of Western capitalism and democracy. Thus arise uncomfortable disjunctions—first, between incommensurable theories that both remain vital forces in public life, and, secondarily, between knowledge and practice. This article explores these contending theoretical formations, disjunctions between them, and illustrates how these disjunctions translate into contemporary argument in U.S. Indian policy.     

Dynamics of Cultural Transmission in Native Americans of the High Great Plains

Culture is a phenomenon shared by all humans. Attempts to understand how dynamic factors affect the origin and distribution of cultural elements are, therefore, of interest to all humanity. As case studies go, understanding the distribution of cultural elements in Native American communities during the historical period of the Great Plains would seem a most challenging one. Famously, there is a mixture of powerful internal and external factors, creating-for a relatively brief period in time-a seemingly distinctive set of shared elements from a linguistically diverse set of peoples. This is known across the world as the “Great Plains culture.” Here, quantitative analyses show how different processes operated on two sets of cultural traits among nine High Plains groups. Moccasin decorations exhibit a pattern consistent with geographically-mediated between-group interaction. However, group variations in the religious ceremony of the Sun Dance also reveal evidence of purifying cultural selection associated with historical biases, dividing down ancient linguistic lines. The latter shows that while the conglomeration of “Plains culture” may have been a product of merging new ideas with old, combined with cultural interchange between groups, the details of what was accepted, rejected or elaborated in each case reflected preexisting ideological biases. Although culture may sometimes be a “melting pot,” the analyses show that even in highly fluid situations, cultural mosaics may be indirectly shaped by historical factors that are not always obvious.

Plains History and Cultural Anthropology

Abstract

Recent cutbacks in research funding and the burgeoning population of anthropology graduate departments may soon force cultural anthropologists to recognize what their archaeological colleagues have long known: their own “backyard” is a field for fertile research. Specifically, cultural anthropologists may turn increasingly to using long-neglected data sources - rich in documentation - on Anglo-Saxon America. This paper briefly investigates some reasons for the study of American historical data and presents a preliminary analysis of some data.     

Native Language Teachers in a Struggle for Language and Cultural Survival

Language shift among New Mexico Pueblo Indians threatens the loss of their oral-based cultures. Language revival for many Pueblos has resulted in school programs in which students are easily accessible and teachers are accountable to tribes rather than the state. Finding "Pueblo space" for the Native language in school, where it was previously targeted for extinction, poses unique challenges. Personal histories and ethnographic interviews provide language teacher perspectives on teaching in four separate school programs.     

Teaching and the Life History of Cultural Transmission in Fijian Villages

Much existing literature in anthropology suggests that teaching is rare in non-Western societies, and that cultural transmission is mostly vertical (parent-to-offspring). However, applications of evolutionary theory to humans predict both teaching and non-vertical transmission of culturally learned skills, behaviors, and knowledge should be common cross-culturally. Here, we review this body of theory to derive predictions about when teaching and non-vertical transmission should be adaptive, and thus more likely to be observed empirically. Using three interviews conducted with rural Fijian populations, we find that parents are more likely to teach than are other kin types, high-skill and highly valued domains are more likely to be taught, and oblique transmission is associated with high-skill domains, which are learned later in life. Finally, we conclude that the apparent conflict between theory and empirical evidence is due to a mismatch of theoretical hypotheses and empirical claims across disciplines, and we reconcile theory with the existing literature in light of our results.

Effects of Competition and Life History Stage on the Expression of Local Adaptation in Two Native Bunchgrasses

Concerns about the use of genetically appropriate material in restoration often focus on questions of local adaptation. Many reciprocal transplant studies have demonstrated local adaptation in native plant species, but very few have examined how interspecific competition affects the expression of adaptive variation. Our study examined regional scales of adaptation between foothill and coastal populations of two California native bunchgrasses (Elymus glaucus and Nassella pulchra). By combining competitive manipulations with reciprocal transplants, we examined the importance of the vegetation at a site as a selective factor in the process of local adaptation. By monitoring survival and reproduction of reciprocally transplanted populations over the course of 3 years, we also studied the effect of life history stage on the expression of local adaptation. For most of the fitness components we measured, local adaptation was detected and interspecific competition consistently amplified its expression. Expression of local adaptation was especially apparent in the more inbreeding species E. glaucus and suggests that with weaker gene flow, selection may be more effective in creating ecotypes within this species. Local adaptation was detected at all life history stages but was most strongly expressed in traits associated with adult reproduction and the viability of seeds produced by the transplants. Taken together, our results indicate that the importance of local adaptation will become more apparent in the later stages of a restoration project as the plants at a site begin to reproduce and as they experience greater interspecific competition from the maturing vegetation at the site.     

Native Alternatives for Non-Native Turfgrasses in Central Florida: Germination and Responses to Cultural Treatments

Little information exists about the establishment of native longleaf pine flatwoods species for use in restoration efforts and as buffers around natural areas in the southeastern United States. Composition of groundcover in these systems is dominated by perennial graminoid species. Vegetation in current buffers is generally non‐native turfgrass that can escape into natural areas, often reducing establishment and survival of native species. Where management objectives involve actively restoring native groundcover or reducing the probability of invasion by these non‐native turfgrasses, identification of native species and restoration methods is needed. We investigated seed germination and establishment of four species native to longleaf pine flatwoods in central Florida and one species native to the adjacent wetland communities. Paspalum setaceum, Panicum anceps, Eustachys petraea, and Eragrostis refracta were directly seeded, and P. distichum was planted as sprigs into three former P. notatum pastures. Irrigation, fertilization, weed control, and mowing treatments were assessed in terms of cover development of the sown species. Paspalum distichum developed the highest percent cover—over 80% in wet areas after 1 year. Mowing had mixed impacts depending on the species, and fertilization never significantly increased cover. Directly seeded species developed sparse cover (0–40%), probably as a result of drought conditions. However, E. petraea and E. refracta appeared more promising for use on rights‐of‐way when using high sowing rates. A second experiment conducted on a roadside included these two species and sprigged P. distichum. Both E. petraea and P. distichum developed more than 45% cover on the roadside. Establishment of these natives from seed or sprigs was significantly enhanced when site preparation effectively reduced the seedbank of other species present in the soil.
