Efficacy of native grassland barriers at limiting prairie dog dispersal in Logan county, Kansas

Eddy, Zachary January 1900 (has links)
Master of Arts / Department of Geography / J. M. Shawn Hutchinson / Prairie dogs (Cynomys spp.) are social, ground-dwelling rodents native to North American short- and mixed-grass prairie. They are also the main prey of the Federally-endangered black-footed ferret (Mustela nigripes). At the same time, prairie dog colonization is highly opposed by most agricultural landowners. Therefore nonlethal population management techniques must be investigated. This paper presents the results of research on the effectiveness of ungrazed vegetative barriers composed of native plants at limiting prairie dog dispersal away from a ferret reintroduction site in northwest Kansas. Data was collected on barrier quality and condition as well as estimates of population densities of immigrant prairie dogs, dispersing through the vegetative barrier to reoccupy previously extirpated colonies on properties surrounding the ferret reintroduction site. Using strip transects and aboveground visual counts to estimate population densities and visual obstruction ranking techniques to sample barrier condition, statistical analysis of the data indicated that while barrier condition increased over time, it was not effective at limiting prairie dog emigration from the black-footed ferret reintroduction site.

Conflitos territoriais no Brasil e o Movimento Indígena contemporâneo /

Santos, Gilberto Vieira dos. January 2019 (has links)
Orientador: Antonio Thomaz Junior / Resumo: Este estudo resulta de uma Pesquisa-Ação sobre o fenômeno “Movimento Indígena” no Brasil. Tem como objetivo apresentar as faces e aspectos mais recentes da constituição do Movimento Indígena no Brasil, com o propósito de analisar as incidências, as alianças, as estratégias e as repercussões de suas ações para o avanço ou no barramento dos retrocessos no tocante aos direitos destes povos. Tal pesquisa teve por base os quinze anos de convivência e atuação junto aos povos indígenas, os elementos apreendidos a partir da revisão bibliográfica e as contribuições de pesquisas de diferentes áreas do conhecimento, como História, Sociologia e Antropologia, além das reflexões e contribuições próprias da Geografia. Ao longo de sua efetivação, acompanhamos ações de lideranças indígenas de diferentes regiões do Brasil na cidade de Brasília (DF) e em outros estados brasileiros. A questão que permeou todo o processo de pesquisa foi, qual o lugar dos povos indígenas no campo da Geografia? Recorri, portanto, a análise da história recente do país a partir da década de 1960, desvelando aspectos da territorialidade própria dos povos, os conflitos estabelecidos na implantação dos projetos de desenvolvimento pelo Estado brasileiro, a resistência e o protagonismo indígena a estes projetos. O estudo nos apontou para a necessidade de que a ciência geográfica aprofunde seu entendimento sobre as dinâmicas próprias do Movimento Indígena, entenda o conceito de território para estes povos e as lutas para m...

This research was based on the fifteen years of coexistence and actions with indigenous peoples, on the elements derived from the bibliographic review, and on the contributions of studies in different areas of knowledge, such as History, Sociology and Anthropology, as well as on the reflections and contributions of Geography itself. Throughout its implementation, we followed actions taken by indigenous leaders from different regions of Brazil in the city of Brasília (Federal District) and in other Brazilian states. The question that permeated the entire research process was, “What is the place of indigenous peoples in the field of Geography?” For this purpose, an analysis of the country’s recent history since the 1960s was undertaken that revealed aspects of the indigenous peoples’ territoriality, the conflicts involved in the implementation of development projects by the Brazilian State, and the resistance of these peoples to these projects and the key role they played in opposing them. The study pointed to the need for geographical science to deepen its understanding of the indigen...
