Ecology of Ticks (Acari: Ixodidae) in Shelterbelts of Southeastern Nebraska

Shelterbelts in the agricultural landscape provide valuable habitat to a variety of animals that in turn may be hosts to ixodid ticks. The purpose of this study is to determine if shelterbelt associated factors influence tick ecology. In 2010 and 2011, ticks were collected from several shelterbelts in southeast Nebraska in Lancaster and Saunders counties. Four tick species were identified. Adjacent land use, shelterbelt composition, and time of day were all factors which did not influence the number of questing ticks collected. Differences in relation to aspect and distance from the shelterbelt were significant. The east side had continually higher numbers of questing ticks than the north, south and west. The duration of tick activity was reduced on the north side. Solar radiation, soil moisture and soil temperature could influence tick emergence from diapause resulting in the first cohort of the year. Based on my findings, the entomological risk for land management can be augmented, tick control strategies can become more effective and less wasteful, and knowledge of the presence of the various species of ticks can impact policies on public health and education.

Liberal Government and the Practical History of Anthropology

This paper explores the implications of Foucault's perspective of liberal government for approaches to the practical history of anthropology. It also draws on assemblage theory to consider the changing relations between field, museum and university in relation to a range of early twentieth-century anthropological practices. These focus mainly on the development of the Boasian paradigm in the USA during the inter-war years and on the anthropological practices clustered around the Musée de l'Homme in the 1930s. Key steps in the argument focus on the role of what Foucault called "transactional realities" in mediating the practical applications of anthropology in colonial contexts and in "anthropology at home" projects. Special consideration is also given to the increasingly archival properties of anthropological collections in the early twentieth century and the consequences of this for anthropology's relations to practices of governing
