Drought In Georgia: Water Scarcity Issues And Implications, Samantha Kay Chaisson

LSU Master's Theses

Population growth and hydrological drought threaten the water supply of Atlanta, Georgia. In Georgia, water policy changed rapidly due to stress on the resource, regulation increased, and the state promoted a “culture of conservation” to combat water scarcity. This study examines how regulatory measures, including legislative acts and Governor’s executive orders, have impacted the population’s attitudes and behaviors towards water consumption. Furthermore, public spaces are used to measure public perception of water policy, and serve as a physical representation of the culture shift.

Paved With Good Intentions: The Fate Of Strict Liability Under The Migratory Bird Treaty Act, Kalyani Robbins Jan 2012

Paved With Good Intentions: The Fate Of Strict Liability Under The Migratory Bird Treaty Act, Kalyani Robbins

Akron Law Faculty Publications

The Migratory Bird Treaty Act (MBTA) contains a very broad ban on harming migratory birds, as well as a strict liability standard for misdemeanor violations. Without further limitation, the MBTA would theoretically apply to countless ordinary life activities, such as driving a car or having windows on one’s home. Naturally, there are due process concerns with such a scenario, so Congress expressly left it to the Department of the Interior to draft more detailed implementing regulations. Unfortunately, the existing regulations fail to adequately address the potential overbreadth of the MBTA’s misdemeanor application, forcing the courts to do so on an …

The Effects Of Spinosad On Culex Quinquefasciatus (Diptera: Culicidae) And Non-Target Insect Species, Owen Mcbride Jones Jan 2012

The Effects Of Spinosad On Culex Quinquefasciatus (Diptera: Culicidae) And Non-Target Insect Species, Owen Mcbride Jones

LSU Master's Theses

Spinosad is a relatively new insecticide with a unique mode of action that is being evaluated for control of larval mosquitoes. Whereas a number of toxicological studies have measured effects of spinosad on various mammals, fish, birds, and terrestrial arthropods, fewer studies have been conducted on the effects of spinosad on non-target aquatic insect species. Such studies are important as these species might be found in the same environments as mosquito larvae targeted for control. A neighborhood pond was surveyed to find a representative species of mosquito as well as other common aquatic insects with which to examine susceptibility to …

Using Ecological Niche Modeling To Resolve Cryptic Taxa Within The Greenside Darter Species Complex, Jack Alphonse Kosmicki Jan 2012

Using Ecological Niche Modeling To Resolve Cryptic Taxa Within The Greenside Darter Species Complex, Jack Alphonse Kosmicki

Honors Program Theses

A major challenge for systematists is clearly identifying species early after a speciation event (Frost and Kluge, 1994; Wiens and Servedio, 2000; Coyne and Orr, 2004). Traditionally species delimitation is made based on morphological characteristics, behavioral differences, and/or genetic data. However, for cryptic species lineages, these approaches do not work as well because the lineages have subtle overlapping morphological and behavioral differences and lineage sorting may not be complete (Raxworthy et al., 2007). A far less common approach is to use ecological niche models (ENMs) to help identify new species. This approach holds strong potential for cryptic species in which …

An Evaluation Of The Species Status Of Physaria Intermedia (Brassicaceae), Katie Arp Jan 2012

An Evaluation Of The Species Status Of Physaria Intermedia (Brassicaceae), Katie Arp

Honors Program Theses

The taxonomy of the genus Physaria (Brassicaceae) has been continually under revision as many species groups have proved difficult to resolve. Physaria intermedia (S. Watson) O'Kane Al-Shehbaz, has been a species whose circumscription has more recently been questioned and in need of clarification. The uncertainty surrounding the species stemmed from a combination of its geographical distribution, inhabiting two disjunct locations, as well as some minor differences in morphology that warranted a closer look. The species had been described as occupying southern Utah, northern and eastern (in northern 2/3) Arizona and southwest New Mexico with the remaining specimens inhabiting an isolated …

The Biodiversity Of Thermoduric Bacteria Isolated From Whey, Joseph Meade, Seamus Fanning, Kevinia Mcgill, Ciara Walsh Jan 2012

The Biodiversity Of Thermoduric Bacteria Isolated From Whey, Joseph Meade, Seamus Fanning, Kevinia Mcgill, Ciara Walsh

Articles

Thermoduric gram-positive bacteria are indigenous in milk, cheese, whey and other dairy products. They are capable of surviving heat processes and can result in quality defects and a shortened product shelf life. In Ireland, premium products such as whey protein concentrate (WPC) are often adversely affected by these microorganisms, particularly during the winter months.A high bacterial count in the WPC can result in the product being sold at a lower grade, with an overall loss of revenue for the manufacturer. This study recovered thermoduric bacterial isolates (n = 140) from an Irish WPC process during the months of November–February.Using molecular …
