The Effect Of Landscape Variables On Adult Mosquito (Diptera:Culicidae)Diversity And Behavior, Caitlyn Debevec
The Effect Of Landscape Variables On Adult Mosquito (Diptera:Culicidae)Diversity And Behavior, Caitlyn Debevec
Electronic Theses and Dissertations
Diseases vectored by mosquitoes cause millions of deaths each year. In modern times Florida*s disease risk has been reduced due to efforts to lessen the prevalence of mosquitoes through habitat modification of non-adults. With emerging diseases (i.e. Dengue and Chikunguya) encroaching into Florida from the Caribbean, this traditional approach may not be enough. Alternatively, we can better understand the ecology of how disease works in an ecosystem. One possible way is through the Dilution Effect, which states that the more species that are in a system the lower the chance for zoonosis. This project models mosquito diversity across regions, land …
Quantifying The Effects Of Boat Wakes On Intertidal Oyster Reefs In A Shallow Estuary, Donna Campbell
Quantifying The Effects Of Boat Wakes On Intertidal Oyster Reefs In A Shallow Estuary, Donna Campbell
Electronic Theses and Dissertations
There have long been concerns about the negative impacts of recreational boating activity in the Indian River Lagoon system (IRL), especially in Mosquito Lagoon (ML), the northernmost part of the IRL. My research is focused on the impacts of boat wakes on intertidal reefs formed by the eastern oyster, Crassostrea virginica. There has been a 24% loss of oyster habitat in ML since 1943, where natural oyster reefs have been replaced by dead oyster reefs which do not serve the same ecological function. While there is anecdotal and correlative evidence that this loss is a result of boat wakes, no …

Development Of Circadian Oscillators In Neurosphere Cultures During Adult Neurogenesis, Astha Malik, Roudabeh J. Jamasbi, Roman V. Kondratov, Michael Eric Geusz
Biological Sciences Faculty Publications
Circadian rhythms are common in many cell types but are reported to be lacking in embryonic stem cells. Recent studies have described possible interactions between the molecular mechanism of circadian clocks and the signaling pathways that regulate stem cell differentiation. Circadian rhythms have not been examined well in neural stem cells and progenitor cells that produce new neurons and glial cells during adult neurogenesis. To evaluate circadian timing abilities of cells undergoing neural differentiation, neurospheres were prepared from the mouse subventricular zone (SVZ), a rich source of adult neural stem cells. Circadian rhythms in mPer1 gene expression were recorded in …
Polychlorinated Biphenyl Exposure Alters Oxytocin Receptor Gene Expression And Maternal Behavior In Rat Model, E Nicole Dover, David E. Mankin, Howard C. Cromwell, Lee Meserve
Polychlorinated Biphenyl Exposure Alters Oxytocin Receptor Gene Expression And Maternal Behavior In Rat Model, E Nicole Dover, David E. Mankin, Howard C. Cromwell, Lee Meserve
Biological Sciences Faculty Publications
Polychlorinated biphenyl (PCB) is a persistent organic pollutant known to induce diverse molecular and behavioral alterations. Effects of PCB exposure could be transmitted to future generations via changes in behavior and gene expression. Previous work has shown that PCB-exposure can alter social behavior. The present study extends this work by examining a possible molecular mechanism for these changes. Pregnant rats (Sprague-Dawley) were exposed through diet to a combination of non-coplanar (PCB 47 - 2,20,4,40-tetrachlorobiphenyl) and coplanar (PCB 77 - 3,30,4,40- tetrachlorobiphenyl) congeners. Maternal care behaviors were examined by evaluating the rate and quality of nest building on the last 4 …

Low-To-Moderate Nitrogen And Phosphorus Concentrations Accelerate Microbially Driven Litter Breakdown Rates, John S. Kominoski, Amy D. Rosemond, Jonathan P. Benstead, Vladislav Gulis, John C. Maerz, David W. P. Manning
Biology Faculty Publications
Particulate organic matter (POM) processing is an important driver of aquatic ecosystem productivity that is sensitive to nutrient enrichment and drives ecosystem carbon (C) loss. Although studies of single concentrations of nitrogen (N) or phosphorus (P) have shown effects at relatively low concentrations, responses of litter breakdown rates along gradients of low‐to‐moderate N and P concentrations are needed to establish likely interdependent effects of dual N and P enrichment on baseline activity in stream ecosystems. We established 25 combinations of dissolved inorganic N (DIN; 55–545 μg/L) and soluble reactive P (SRP; 4–86 μg/L) concentrations with corresponding N:P molar ratios of …
Toxicity Of Leaf Extract Of Acer Spp. On Equine Erythrocytes, Bailey Katherine Dye
Toxicity Of Leaf Extract Of Acer Spp. On Equine Erythrocytes, Bailey Katherine Dye
Undergraduate Honors Thesis Projects
Red maple toxicosis is a phenomenon that occurs in equines after the consumption of dried or wilted red maple (Acer rubrum L.) leaves. Within the erythrocytes, it causes hemolysis, methemoglobinemia, and Heinz body development. The toxic agent of red maple leaves has not yet been identified; however, the development of hemolytic anemia and methemoglobinemia in equines after ingestion of the leaves, suggests that the toxin is acting as a strong oxidant. Some studies have noted that not only are wilted red maples leaves toxic to equines, but that wilted leaves of other maple species may also be toxic. Therefore, …
The Effects Of Hibernation On The Hemostatic Properties Of The American Bullfrog, Rana Catesbeiana, Kiana Cullinan
The Effects Of Hibernation On The Hemostatic Properties Of The American Bullfrog, Rana Catesbeiana, Kiana Cullinan
Honors Program Theses
It is known that hibernating animals display a drastic reduction in metabolic rate, accompanied by reduced heart rate and rate of blood flow through vessels. Sluggish blood flow increases the risk for developing clots, yet it has been observed that hibernators conclusively display elongated clotting times. This observed impairment may be caused by the decrease in body temperature, due to a negative impact on the functioning of the enzymes involved in coagulation. Some hibernating endotherms, or “warm-blooded” animals, employ biological mechanisms as preventative means to prevent clotting during hibernation, such as the down-regulation of certain clotting factors or the production …
