Spontaneous Plant Colonization Of Newly Established Green Roofs: An Experimental Approach, Braden Matthew Coats

Masters Theses

Urban Heat Island Effect (UHI) increases heat risks in densely developed environments. Ecosystem services provided by green spaces are known to mitigate UHI. Green roofs, designed as novel ecosystems, transform less-utilized spaces like rooftops into functional areas, executing ecosystem functions in densely populated urban environments where traditional green spaces are less common. Research has examined ways to reduce the obstacles of implementing green roofs to maximize accessibility and efficiency of the performed ecosystem services. Research involving plant community dynamics found that maximizing biodiversity on green roofs enhances the ecosystem services provided. Utilizing spontaneous colonizing species, or species that are not …

Effects Of Switchgrass Related Land-Use Changes On Aquatic Macroinvertebrates, Latha Malar Baskaran

Doctoral Dissertations

This research examines if switchgrass-based land-management practices have the potential to influence aquatic macroinvertebrates through changes in stream flow and water quality. The number of taxa in Ephemeroptera, Plecoptera, and Trichoptera orders (EPT taxa richness/EPT-TR) is analyzed as an aquatic macroinvertebrate bioindicator in the context of regional environmental effects, and changes in stream flow and water quality. This dissertation is structured as three manuscripts that link together to address the overall research question.

The first manuscript focuses on identifying regional environmental variables that influence EPT-TR across ecoregions in Tennessee. The influences of temperature, precipitation, geology, soil, stream flow and velocity …

Communicating Sustainable Design Through Visual Dynamics, Phillip Walter Zawarus

Masters Theses

My thesis is the exploration of dynamic methods to eff ectively visualize and communicate sustainable designpractices. Every site consists of temporal conditions (climate, vegetation growth, hydrology, comfort, aesthetics)that require dynamic representation of it’s progressive state. By understanding both the quantitative and qualitivemeasures of a site’s content, designers can begin to create guidelines and adaptive responses to the changingconditions. Th is can be achieved by fi rst understanding the intergrated relationship of those conditions, as oneelement has a direct or indirect impact on another. Th e design, in turn, cannot be a static implimentation butrather an evolutionary application.
