Toward A Thomistic Environmental Ethic: How Aquinas's Metaethic Provides The Groundwork For An Environmentally And Zoologically Responsible Moral System, William Merle Green

Masters Theses

While the trend in contemporary discussions of environmental ethics is often to dispense with traditional anthropocentric conceptions of morality in favor of more biologically and ecologically inclusive perspectives, I will argue that Natural Law Theory and Virtue Ethics, both integral components of the moral philosophy of Thomas Aquinas, provide the groundwork for an ecologically and zoologically responsible ethic. Thus, utilizing the core of Aquinas’s ethical system, I will attempt to construct a robust moral framework that is Thomistic in every important sense while at the same time satisfies the sufficiency conditions for a successful environmental code of conduct.

From Land To Lake: Contrasting Microbial Processes Across A Great Lakes Gradient Of Organic Carbon And Inorganic Nutrient Inventories, Deborah K. Dila

Masters Theses

Freshwater ecosystems have strong linkages to the terrestrial landscapes that surround them, and contributions of carbon and inorganic nutrients from soil, vegetation and anthropogenic sources subsidize autochthonous water body productivity to varying degrees. Abundant freshwater phytoplankton and bacterioplankton are key to linking the planet's geosphere and atmosphere to the food webs in the hydrosphere through their growth and respiration. Rich resources that move through land margin waterways make them active sites for cycling organic carbon and thus important, but understudied, contributors to global climate. During 2010-2011, we examined seasonal changes in carbon and nutrient inventories, plankton community composition and metabolism …

Trophic Transfer Of A Naturally Occurring Algal Toxin From A Freshwater Lake To Little Brown Bats, Devin Jones

Masters Theses

Microcystis aeruginosa is a species of cyanobacteria capable of producing a hepatotoxin called microcystin. As toxic M. aeruginosa overwinters in the sediments of lakes, it is ingested by some mayfly larvae, such as those of Hexagenia spp., and thus

microcystin bioaccumulates in these insects. When Hexagenia emerge from lakes to

reproduce, they provide an abundant, albeit temporary, food source for many terrestrial

organisms such as bats. Little brown bats, Myotis lucifugus, likely feed opportunistically

on aquatic insects. To test if microcystin moves from aquatic to terrestrial ecosystems via trophic transfer, we 1) tested bat feces for the presence of …

Examining The Effect Of Climate Change On The Upper Mesophotic Coral Montastrea Cavernosa (Linnaeus 1767), John Skutnik

Masters Theses

Coral reefs are under increasing pressure from global climate change. In particular, ocean warming is having a deleterious effect on many of the world’s shallow reefs. Some authors suggest that acute exposure is more detrimental than chronic, versus others who indicate the opposite. However, little knowledge exists regarding heat induced stress on deeper mesophotic reefs. Here, I examined the effect of acute (72 hrs.) and chronic (480 hrs.) heat stress using laboratory experiments on coral Montastraea cavernosa (Linnaeus 1767) collected from an upper mesophotic (~30 m) reef off Islamorada Florida. I examined a variety of putative immune and stress genes …

Sequestered Alkaloid Defenses In The Dendrobatid Poison Frog Oophaga Pumilio Provide Variable Protection From Microbial Pathogens, Kyle Hovey

Masters Theses

Amphibians produce the majority of their defensive chemicals, however alkaloid defenses in poison frogs are sequestered from dietary arthropods. Alkaloids function as a defense against predators, and certain types appear to inhibit microbial growth. However, alkaloid defenses vary considerably among populations of poison frogs, reflecting geographic differences in availability of dietary arthropods. Consequently, environmentally driven differences in poison frog alkaloid defenses may have significant implications regarding their protection against pathogens. While natural alkaloid mixtures in poison frogs have recently been shown to inhibit growth of non-pathogenic microbes, no studies have examined the effectiveness of alkaloids against microbes that infect frogs. …

Die Phantasie Gottes: An Analysis Of The Divine Ideas In Deity Theories And Brian Leftow, With A Proposed Synthesis, Nathaniel Dowell
