An Exceptionally Small New Polycotylid Plesiosaur (Reptilia: Sauropterygia) With Raptorial Eyes From The Western Interior Seaway Of North America, Robert O’Brien Clark
An Exceptionally Small New Polycotylid Plesiosaur (Reptilia: Sauropterygia) With Raptorial Eyes From The Western Interior Seaway Of North America, Robert O’Brien Clark
Theses, Dissertations and Capstones
Polycotylidae is a family of plesiosaurian marine reptiles that evolved during the Early Cretaceous and radiated into multiple genera during the Late Cretaceous, achieving a worldwide distribution. Derived polycotylids of the subclade Polycotylinae have a gracile and elongated rostrum, homodont dentition, an extended mandibular symphysis, and foreshortened temporal fenestrae. In this thesis, I describe a small and highly derived new polycotylid taxon based on three specimens from the Campanian of the Western Interior Seaway in North America. A high number of maxillary teeth, fused neural arches, propodials with well-defined facets, and heavily remodeled cortical bone indicate the specimens are adults, …
Modeling Chlorophyll Concentrations On The Ohio River Using Remotely Sensed Data, Thaddaeus Stephen Tuggle
Modeling Chlorophyll Concentrations On The Ohio River Using Remotely Sensed Data, Thaddaeus Stephen Tuggle
Theses, Dissertations and Capstones
Traditional direct water quality methodologies limit the ability to spatially and temporally predict algal blooms in lotic systems due to the size and characteristics of large river systems. Algal blooms potentially can be predicted by knowing the spatial and temporal patterns of change in cyanobacteria concentrations at large scales. Remote sensing studies investigating freshwater algal blooms, some known to secrete harmful toxins, are primarily conducted on lentic systems while large lotic systems are greatly ignored. In this study I developed a chlorophyll concentration estimation model for the Ohio River using a satellite remote sensing approach. Ground-truth water quality measures, including …
The Life History Of Faxonius Rusticus (Girard, 1852) In Sunfish Creek, Monroe County, Ohio, Kyle Mcgill

Theses, Dissertations and Capstones
Crayfish are among the most imperiled faunal groups globally. The continued spread of invasive species is a major impact to crayfish. Invasive species, much like the native species, are often understudied. As declines continue, invasive species spread, and new species are discovered; additional life history studies are as important as ever for crayfish conservation. Life history data was collected for rusty crayfish (Faxonius rusticus) from October 2017 to September 2018 in Sunfish Creek, Monroe County, Ohio. Faxonius rusticus are native to the Ohio River drainage around Cincinnati, Ohio but have extensively expanded their range over the past 30 years. Sunfish …
Diversity Of The Ohio River Bacterial Communities Using Next-Generation Sequencing Techniques, Emily Michele Anneken
Diversity Of The Ohio River Bacterial Communities Using Next-Generation Sequencing Techniques, Emily Michele Anneken
Theses, Dissertations and Capstones
The ability to sequence bacterial genetic material directly from environmental samples has unlocked the field of metagenomics. Next-generation sequencing techniques, such as pyrosequencing, have been instrumental in providing knowledge about bacterial communities. This study focused on identifying the bacterial diversity of the Ohio River via pyrosequencing and compared the diversity of cultivable bacteria versus the entire river community. To ensure the maximum number of cultivable bacteria was obtained, cultures were grown on nonselective media and incubated at river temperature. Bacterial DNA was extracted, sequenced, and classified. The dominant phyla for the Ohio River included Cyanobacteria (38-66% of the total), Actinobacteria …
Chronic Toxicity Testing In Mining Influenced Streams Of West Virginia, Leah J. Bitzer
Chronic Toxicity Testing In Mining Influenced Streams Of West Virginia, Leah J. Bitzer
Theses, Dissertations and Capstones
Whole effluent toxicity (WET) tests have become a common tool in the evaluation of effluent for discharge acceptability. In this study, four years of toxicity data from 119 sampling locations were analyzed to determine relationships with ions and conductivity as indicators of toxicity. West Virginia Stream Condition Index (WVSCI) scores were also examined to evaluate correlations between stream scores, conductivity, and IC25 endpoints from toxicity results. Conductivity was not an indicator of toxicity in the range of conductivities tested. Streams dominated by mining effluent sometimes exhibited toxicity to Ceriodaphnia dubia; however, toxicity was not found to be related to ionic …
Dopamine Modulates The Lateral Giant Neuron And Serotonergic Facilitation In Crayfish, Joshua Scott Titlow
Dopamine Modulates The Lateral Giant Neuron And Serotonergic Facilitation In Crayfish, Joshua Scott Titlow
Theses, Dissertations and Capstones
The lateral giant (LG) neural circuit is a model system used to study the function of individual neurons. The LG circuit is part of a tail flip escape reflex that is a defensive behavior for crayfish. This thesis begins by addressing the effects of dopamine (DA), a neurotransmitter involved in normal and abnormal behaviors of most animals. Here it is shown that dopamine decreases the excitability of the LG neuron, a trigger for the escape reflex. An electrophysiology protocol was used to mimic sensory input to the LG neuron. Stimulating a sensory nerve in the last ganglion with an electrode …

Theses, Dissertations and Capstones
The Ohio River extends 981 miles from Pittsburgh, PA to Cairo, Ill providing drinking water to over three million people, a natural habitat for aquatic life, a public recreation resource, a major transportation route, and a source of water for industry. The Guyandotte River is a highly impacted tributary emptying into the Ohio River in Huntington, WV. The objectives of this study were to determine if sediment load is correlated to the number of antibiotic resistant bacteria (ARB) and determine if a single surface sample is a sufficient representative measurement of ARB populations in a large river. In 2007, subsurface …
Developing A Monitoring Protocol For The Monkey River Watershed, Belize, Central America, Sean Elliott Collins
Developing A Monitoring Protocol For The Monkey River Watershed, Belize, Central America, Sean Elliott Collins
Theses, Dissertations and Capstones
The study of tropical aquatic systems has been limited. Research in developing countries can be challenging due to inadequate resources and cultural variety. Generally, efforts are concentrated on developing and maintaining economic stability rather than ecological sustainability. The aim of this project was to preliminarily develop and utilize a rapid bioassessment protocol (RBP) for the Monkey River watershed in Belize by determining which metrics best described overall stream health. Like biomonitoring protocols already established for temperate systems, a regional tropical aquatic watershed monitoring program should provide information including stream and watershed health. These protocols score systems on a variety of …

Application Of Remote Sensing To Examine Changes In Bird Communities Over A Gradient Of Urbanization, John E. Northeimer
Theses, Dissertations and Capstones
Interest in urban ecology and the impact of urbanization on natural resources has increased over the last decade. Studies have related degradation of water quality and loss of biodiversity to increased urbanization. Avian species comprise an important part of the urban ecology. Surveys of bird populations can provide insight into the effects of urbanization on species composition, diversity, and distribution. A search of available literature revealed no published comprehensive avian surveys completed during the breeding season within the city of Huntington, West Virginia. The purpose of this study was to provide an initial characterization of land bird populations during the …
Characterization Of Unusual Gymnamoebae Isolated From The Marine Environment, Margaret Wacera Mbugua
Characterization Of Unusual Gymnamoebae Isolated From The Marine Environment, Margaret Wacera Mbugua
Theses, Dissertations and Capstones
Amoebae are important heterotrophic protists (protozoa) and this study focuses on three unusual forms from the marine environment. Amoebae are ubiquitous and play an important role as consumers in microbial communities. A common coastal ctenophore (Mnemiopsis sp.) is known to harbor an undescribed naked amoeba on the comb plate surface. The nature of the symbiotic association is unknown although electron microscopy suggests these micrograzers are degrading comb plates (Moss et al., 2001). A second amoeba isolate from mangrove waters is new to science by virtue of its distinctive trophic form that does not conform to any described species. …
