Integrating, Developing, And Testing Methods To Generate More Cohesive Approaches To Biogeographic Inference, Mallory Elizabeth Eckstut May 2013

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.

Green Roof Biodiversity In Design: Influence Of Local And Contextual Attributes On Bird Usage, Henry Narigon Jan 2013

Green Roof Biodiversity In Design: Influence Of Local And Contextual Attributes On Bird Usage, Henry Narigon

Graduate Theses and Dissertations

This purpose of this research is to identify how species of birds use urban green roofs in Iowa with the intent to eventually develop a set of guidelines for optimizing habitat on green roofs. Ten green roofs were observed for bird usage five times each between May to August, 2013 for a total of fifty observations. Birds were identified by species and their behavior was recorded during the duration of the observations. Data shows that birds use green roofs for a number of uses including foraging and gathering nest material. Bird diversity data was then compared with both green roof ...


Applying The Principles Of Spatial Modelling To The Management Of Biodiversity In The Fragmented Landscapes Of South-Western Australia, Shaun Molloy Jan 2013

Applying The Principles Of Spatial Modelling To The Management Of Biodiversity In The Fragmented Landscapes Of South-Western Australia, Shaun Molloy

Theses: Doctorates and Masters

Biodiversity conservation throughout the world is challenged by the impacts of a changing climate on fragmented landscapes. To mitigate these threats, conservation managers require models which can demonstrate the consequences of both negative impacts and management actions. This need can be addressed through spatial modelling applications. Unfortunately, throughout much of the world, spatial modelling is forgone, being seen as requiring skills and resources beyond the means of many conservation planners and managers. This thesis seeks to address this dilemma by delivering criteria for a successful modelling application and by providing case studies which demonstrate how appropriate modelling can be undertaken ...
