Investigating The Spatial Distribution And Effects Of Nearshore Topography On Acropora Cervicornis Abundance In Southeast Florida, Nicole D'Antonio, David S. Gilliam, Brian K. Walker Sep 2016

Investigating The Spatial Distribution And Effects Of Nearshore Topography On Acropora Cervicornis Abundance In Southeast Florida, Nicole D'Antonio, David S. Gilliam, Brian K. Walker

Marine & Environmental Sciences Faculty Articles

Dense Acropora cervicornis aggregations, or patches, have been documented within nearshore habitats in Southeast Florida (SE FL) despite close proximity to numerous anthropogenic stressors and subjection to frequent natural disturbance events. Limited information has been published concerning the distribution and abundance of A. cervicornis outside of these known dense patches. The first goal of this study was to conduct a spatially extensive and inclusive survey (9.78 km2) to determine whether A. cervicornis distribution in the nearshore habitat of SE FL was spatially uniform or clustered. The second goal was to investigate potential relationships between broad-scale seafloor topography and …


A Physiologically-Based Pharmacokinetic Model For The Antibiotic Levofloxacin, Paezha M. Mccartt May 2016

A Physiologically-Based Pharmacokinetic Model For The Antibiotic Levofloxacin, Paezha M. Mccartt

Undergraduate Honors Theses

Levofloxacin is in a class of antibiotics known as fluoroquinolones, which treat infections by killing the bacteria that cause them. A physiologically-based pharmacokinetic (PBPK) model was developed to investigate the uptake, distribution, and elimination of Levofloxacin after a single dose. PBPK modeling uses parameters such as body weight, blood flow rates, partition coefficients, organ volumes, and several other parameters in order to model the distribution of a particular drug throughout the body. Levofloxacin is only moderately bound in human blood plasma, and, thus, for the purposes of this paper, linear bonding is incorporated into the model because the free or …

A Lobed Argiope Spider On Its Most Eastern Distribution – First Record Of Argiope Lobata (Pallas, 1772) For The Sub-Family Argiopinae (Arachnida: Araneidae) In Mongolia, Oliver Lindecke, Marcus Wall Jan 2016

A Lobed Argiope Spider On Its Most Eastern Distribution – First Record Of Argiope Lobata (Pallas, 1772) For The Sub-Family Argiopinae (Arachnida: Araneidae) In Mongolia, Oliver Lindecke, Marcus Wall

Erforschung biologischer Ressourcen der Mongolei / Exploration into the Biological Resources of Mongolia, ISSN 0440-1298

The subfamily Argiopinae SIMON, 1890 is reported for Mongolia the first time by Argiope lobata (PALLAS, 1772). Furthermore, we herein highlight the most eastern distribution of this species, which is widespread in the Mediterranean, African and in some Asian countries. The obtained specimen was found in the Eastern Gobi, a landscape of semi-desert character. Despite numerous studies with arachnological background in the past, even larger species new for Mongolia could be found. Findings like this show the on-going need for basic biodiversity research in the Gobi ecoregions. We further discuss previous, but doubtful reports of A. lobata in South-east Asia …

Erforschung biologischer Ressourcen der Mongolei / Exploration into the Biological Resources of Mongolia, ISSN 0440-1298

In November 2009, we conducted a countrywide survey for wild sheep or argali and Siberian ibex. Field survey teams sampled in total 134 argali distribution units within Mongolia, which are estimated to occupy approximately 46,603 km² of the whole area of 60,237 km² that been previously mapped as populated by argali. They observed 385 groups of argali, totaling 3.373 individuals. Our point estimate of argali is 18,140 with a lower 95% confidence limit of 9,193 and an upper 95% confidence limit of 43,135.

At the same time the authors observed 162 groups of ibex, totaling 2,541 individuals and our point …


Geographical Distribution Of The Genus Mesobuthus (Scorpiones: Buthidae) In Mongolia, Mike Heddergott, Michael Stubbe, W. Stubbe, P. Steinbach, Annegret Stubbe Jan 2016

Geographical Distribution Of The Genus Mesobuthus (Scorpiones: Buthidae) In Mongolia, Mike Heddergott, Michael Stubbe, W. Stubbe, P. Steinbach, Annegret Stubbe

Erforschung biologischer Ressourcen der Mongolei / Exploration into the Biological Resources of Mongolia, ISSN 0440-1298

In the present study, we surveyed the diversity of scorpions in six provinces of Mongolia (Bayankhongor, Khovd, Dundgovi, Dornogovi, Govisümber and Ömnögovi) between 2001 and 2012. A total of 385 individuals were collected at 17 different sites. In addition to opportunistic sampling, animals were collected after detection with ultraviolet light. Only species from the genus Mesobuthus have been reported from Mongolia thus far. It was possible to confirm the occurrence of the species Mesobuthus eupeus mongolicus and report the presence of M. martensii martensii for the first time. We could not confirm the presence of M. caucasicus przewalskii and suggest …


Dentine Oxygn Isotopes (Δ18o) As A Proxy For Odontocete Distributions And Movements., Cory J.D. Matthews, Fred J. Longstaffe, Steven H. Fergispm Jan 2016

Dentine Oxygn Isotopes (Δ18o) As A Proxy For Odontocete Distributions And Movements., Cory J.D. Matthews, Fred J. Longstaffe, Steven H. Fergispm

Earth Sciences Publications

Spatial variation in marine oxygen isotope ratios ( δ18O) resulting from differential evaporation rates and precipitation inputs is potentially useful for characterizing marine mammal distributions and tracking movements across δ18O gradients. Dentine hydroxyapatite contains carbonate and phosphate that precipitate in oxygen isotopic equilibrium with body water, which in odontocetes closely tracks the isotopic composition of ambient water. To test whether dentine oxygen isotope composition reliably records that of ambient water and can therefore serve as a proxy for odontocete distribution and movement patterns, we measured δ18O values of dentine structural carbonate (δ18 …

Species Discovery And Diversity In Lobocriconema (Criconematidae: Nematoda) And Related Plant-Parasitic Nematodes From North American Ecoregions, Tom Powers, Ernest C. Bernard, T. Harris, Robert Higgins, M. Olson, S. Olson, M. Lodema, Julianne N. Matczyszyn, P. Mullin, L. Sutton, K.S Powers

Department of Statistics: Faculty Publications

There are many nematode species that, following formal description, are seldom mentioned again in the scientific literature. Lobocriconema thornei and L. incrassatum are two such species, described from North American forests, respectively 37 and 49 years ago. In the course of a 3-year nematode biodiversity survey of North American ecoregions, specimens resembling Lobocriconema species appeared in soil samples from both grassland and forested sites. Using a combination of molecular and morphological analyses, together with a set of species delimitation approaches, we have expanded the known range of these species, added to the species descriptions, and discovered a related group of …


Der Mönchsgeier Aegypius Monachus (L., 1766) Und Seine Mallophagen (Insecta, Phthiraptera) In Der Mongolei = Cinereous Vulture Aegypius Monachus (L., 1766) And Its Chewing Lice (Insecta, Phthiraptera) In Mongolia, Eberhard Mey, Michael Stubbe, Davaa Lchagvasuren, Annegret Stubbe Jan 2016

Der Mönchsgeier Aegypius Monachus (L., 1766) Und Seine Mallophagen (Insecta, Phthiraptera) In Der Mongolei = Cinereous Vulture Aegypius Monachus (L., 1766) And Its Chewing Lice (Insecta, Phthiraptera) In Mongolia, Eberhard Mey, Michael Stubbe, Davaa Lchagvasuren, Annegret Stubbe

Erforschung biologischer Ressourcen der Mongolei / Exploration into the Biological Resources of Mongolia, ISSN 0440-1298

During a series of studies on the population, ecology, and biology of the Cinereous Vulture in Mongolia, fully feathered nestlings of the species from 9 nests were examined, without the use of chemical methods, for Mallophaga infestation from 2010 to 2015. The collection resulted in several first records for Mongolia of three species: Laemobothrion vulturis (J. C. FABRICIUS, 1775) sensu lato (Amblycera, Laemobothriidae), Neocolpocephalum aegypii (TENDEIRO, 1989) (Amblycera, Menoponidae s. l.) sp. inq., and Falcolipeurus quadripustulatus (BURMEISTER, 1838) (Ischnocera, Philopteridae s. l.). Despite being expected, there has still been no record of Agypoecus brevicollis (BURMEISTER, 1838) in Mongolia.

Manipulation Of Nanoscale Domain Switching Using An Electron Beam With Omnidirectional Electric Field Distribution, Zi-Bin Chen, Xiaolin Wang, Simon Peter Ringer, Xiaozhou Liao Jan 2016

Manipulation Of Nanoscale Domain Switching Using An Electron Beam With Omnidirectional Electric Field Distribution, Zi-Bin Chen, Xiaolin Wang, Simon Peter Ringer, Xiaozhou Liao

Australian Institute for Innovative Materials - Papers

Reversible ferroelectric domain (FD) manipulation with a high spatial resolution is critical for memory storage devices based on thin film ferroelectric materials. FD can be manipulated using techniques that apply heat, mechanical stress, or electric bias. However, these techniques have some drawbacks. Here we propose to use an electron beam with an omnidirectional electric field as a tool for erasable stable ferroelectric nanodomain manipulation. Our results suggest that local accumulation of charges contributes to the local electric field that determines domain configurations.


Small-Scale Biogeographic Patterns Of Benthic Bacterial And Ciliate Communities In The Saline Ponds Of Lake Macleod, North-Western Australia, Christopher Kavazos Jan 2016

Small-Scale Biogeographic Patterns Of Benthic Bacterial And Ciliate Communities In The Saline Ponds Of Lake Macleod, North-Western Australia, Christopher Kavazos

Theses: Doctorates and Masters

This biogeographical thesis tests for the presence of taxa-area and distance-decay relationships, which are common among macrobionts, in prokaryotic (bacterial) and micro-eukaryotic (ciliate) communities. Microbial biogeographical patterns may be distinct because of the high abundances, diversity and dispersal capabilities of microbes, in comparison to macrobionts. The Northern Ponds of Lake MacLeod, north-western Australia, provide an ideal location to address this topic, because the ponds are effectively hydrogeomorphologically identical, other than in surface area, and biotic histories can be assumed to differ only according to distance of separation. This means that hypotheses concerning species-sorting and neutral processes on microbial assemblages can …


The Reflected-Shifted-Truncated-Gamma Distribution For Negatively Skewed Survival Data With Application To Pediatric Nephrotic Syndrome, Sophia D. Waymyers Jan 2016

The Reflected-Shifted-Truncated-Gamma Distribution For Negatively Skewed Survival Data With Application To Pediatric Nephrotic Syndrome, Sophia D. Waymyers

Theses and Dissertations

Negatively skewed survival data arise occasionally in public health fields and in statistical research. Standard distributions such as the exponential, generalized F, generalized gamma, Gompertz, log-logistic, lognormal, Rayleigh, and Weibull distributions are not always well suited to this data. The primary goal of this dissertation is to find a viable alternative for modeling negatively skewed survival data such as the time to first remission for pediatric patients with frequently relapsing or steroid dependent nephrotic syndrome.

We begin with a brief introduction of survival analysis and the nature of pediatric nephrotic syndrome. A meta-analysis on atopy and pediatric nephrotic syndrome using …


Invasive Plant Ecology In Vermont: Insights From Spatial Analysis And Interactions Of Garlic Mustard (Alliaria Petiolata) With Native Plants And Invertebrates, Chenin Kathleen Limback Jan 2016

Invasive Plant Ecology In Vermont: Insights From Spatial Analysis And Interactions Of Garlic Mustard (Alliaria Petiolata) With Native Plants And Invertebrates, Chenin Kathleen Limback

Graduate College Dissertations and Theses

Causes and patterns of invasive plant species establishment and success depend broadly upon their ecology, including habitat suitability and interactions with other plants and animals. Here I examine the traits and distribution of invasive plants in Vermont, using spatial analysis, laboratory and field studies. I used GIS to investigate environmental factors correlated with presence of 19 invasive plant species in Vermont campgrounds. My results support the assumption that human dispersal of invasive plant seed and stock may be more important than natural dispersal of these plant species to new sites. I also investigate in-depth the relationships of invasive herbaceous garlic …
