The Evolutionary Biology Of Vision In Daphnia, Christopher S. Brandon Jan 2015

The Evolutionary Biology Of Vision In Daphnia, Christopher S. Brandon

Theses and Dissertations

Eyes have attracted the attention of evolutionary biologist since the field’s infancy. In On the Origin of Species, in fact, Darwin famously remarked on the proposition that natural selection could engineer the eye, saying “[it is] absurd in the highest possible degree.” Though, he goes on to explain, beautifully and simply, how his theory of evolution by natural selection could produce such an organ. Indeed, eyes are remarkable examples of complex information acquisition systems that have evolved from simple beginnings. Eyes allow animals to extract environmental information from light, which informs physiological and behavioral responses to resources, predation, and mates. …

Potential Range Expansion Of The Invasive Lionfish In The Western Atlantic Ocean, Brian Grieve Jan 2015

Potential Range Expansion Of The Invasive Lionfish In The Western Atlantic Ocean, Brian Grieve

Theses and Dissertations

Lionfish (Pterois volitans) are an invasive, predatory fish native to the reefs of the Indo-Pacific. In the mid-1980s, lionfish were introduced off the coast of Miami, FL and have since transformed many of the reef ecosystems throughout the Western Atlantic Ocean. Although lionfish are found year-round as far north as Cape Hatteras, NC, they are confined to the warm Gulf Stream during winter months. Seasonal inshore expansion is possible in the summer, and further poleward expansion is limited by cold bottom-water temperatures in winter. Here, I use an ensemble of 17 different climate models to project lionfish habitat by the …

Patterns Of Selection Amongst Dengue Virus Serotypes And Efficacy Of Computational Epitope Prediction Applications, April Christina Hall South

Theses and Dissertations

Dengue virus (DENV) is a mosquito-borne virus of global concern that leads to infections with symptoms ranging from high fevers and headaches to death. Current estimates place almost half the world’s population living in areas that are at-risk for infection by dengue and that area continues to expand over time. There are four distinct serotypes of dengue (DENV1, DENV2, DENV3, and DENV4). Disease severity from dengue infection is significantly worse if there is a secondary infection by a heterotypic serotype. The problems of increased severity with secondary infection as well as host immune response evasion by the virus itself have …

Marine Population Connectivity: Range Boundaries And Climate Change, Rhiannon Leigh Rognstad Dec 2014

Marine Population Connectivity: Range Boundaries And Climate Change, Rhiannon Leigh Rognstad

Theses and Dissertations

Population connectivity, particularly in open systems, is an important metric for understanding population-level processes on both ecological and evolutionary timescales. In coastal marine systems, adults are typically sedentary and dispersal occurs primarily during a larval stage when individuals are transported in ocean currents. Because coastal marine populations exist as networks of interconnected subpopulations, variation in the magnitude and extent of population connectivity can have profound effects on population dynamics and species distribution limits. Connectivity is a complex process, affected by a multitude of factors, including adult inputs and physical dispersal, which operate at multiple scales and may interact. This dissertation …

Global Climate Change And The Southern Ocean: How Antarctic Fishes Physiologically Respond To A Changing Environment From The Cellular To The Organismal Level, Laura A. Enzor

Theses and Dissertations

Studies have projected that future changes in sea surface temperature and pCO2 levels will impact higher latitudes to a greater extent than in temperate regions. For notothenioid fishes of the Southern Ocean, evolution in extremely stable, cold waters has resulted in several adaptations which have left these fishes poorly prepared for global climate change. I have analyzed the metabolic and cellular response of Trematomus bernacchii, Pagothenia borchgrevinki and Trematomus newnesi to a long-term, multi-stressor scenario relevant to the predicted changes in the Southern Ocean. By combining whole animal respirometry with cellular level analysis of energy allocation, osmoregulatory mechanisms and cellular …


The Roles Of Gsk-3ss And Apc In Cytoplasmic Dynein Regulation, Feng Gao Dec 2014

The Roles Of Gsk-3ss And Apc In Cytoplasmic Dynein Regulation, Feng Gao

Theses and Dissertations

Dynein is a microtubule minus-end directed molecular motor, participating in a broad range of cellular functions, such as organelle transport, cell migration and mitosis. Dynein dysfunction is linked to many diseases including ALS, schizophrenia, Alzheimer’s disease, Parkinson’s disease and cancer. The mechanism of dynein regulation is largely unknown. We have provided evidence that glycogen synthase kinase 3β (GSK-3β) directly regulates dynein in both neurons and non-neuronal cells. GSK-3β interacts with and phosphorylates dynein in vitro. Dynein phosphorylation by GSK-3β reduces its interaction with Ndel1, a regulator contributing to dynein force generation. Dynein motility is stimulated both by pharmacological GSK-3β inhibitors …
