Integrating, Developing, And Testing Methods To Generate More Cohesive Approaches To Biogeographic Inference, Mallory Elizabeth Eckstut

UNLV Theses, Dissertations, Professional Papers, and Capstones

As a fundamental component of the developing discipline of conservation biogeography, broadscale analyses of biotic assembly and disassembly across multiple temporal and spatial scales provide an enhanced understanding of how geologic transformations and climate oscillations have shaped extant patterns of biodiversity. As with any scientific field, there are limitations in the case of biogeographic historical reconstructions. Historical reconstructions are only as robust as the theoretical underpinnings of the methods of reconstruction (including data collection, quality, analysis, and interpretation). Nevertheless, historical reconstructions of species distributions can help inform our understanding of how species respond to environmental change.

Defining Neighborhood: Social Disorganization Theory, Official Data, And Community Perceptions, Jeremy Waller

UNLV Theses, Dissertations, Professional Papers, and Capstones

While the theory of social disorganization has been refined through research and critique, data and methods used to measure key concepts related to the theory have largely remained the same. This study examines the extent to which resident perceptions of neighborhoods are reflected similarly in official data provided by the U.S. Census, in terms of both neighborhood boundaries and neighborhood conditions. It consists of a combination of respondent-identified data and official data gathered on neighborhoods, their condition, and crime. Comparisons between perceptual indicators of neighborhood boundary and characteristics and corresponding official data at the block, block group, and Census tracts …
