Spatial And Temporal Distributions Of Dust And Ammonia Concentrations In A Swine Building, Sheryll B. Jerez, Yuanhui Zhang, X Wang

Faculty Publications

Pollutants, especially dust, are rarely uniformly distributed within ventilated air spaces due to non‐uniform flow fields, particle inertia, gravitational settling, and diffusion. Thus, selecting suitable sampling locations for representative sampling is a challenge. The objective of this study was to determine the spatial and temporal distributions of dust and ammonia concentrations(NH3) in a swine building. Results of this study are useful in the design of sampling strategies that require limited sampling locations and in studying pollutant transport. This study was conducted in a commercial swine building in Illinois. The total suspended particulate (TSP) matter and ammonia concentrations were measured at …

Abstract

Background

Microinversions are cytologically undetectable inversions of DNA sequences that accumulate slowly in genomes. Like many other rare genomic changes (RGCs), microinversions are thought to be virtually homoplasy-free evolutionary characters, suggesting that they may be very useful for difficult phylogenetic problems such as the avian tree of life. However, few detailed surveys of these genomic rearrangements have been conducted, making it difficult to assess this hypothesis or understand the impact of microinversions upon genome evolution.

Results

We surveyed non-coding sequence data from a recent avian phylogenetic study and found substantially more microinversions than expected based upon prior information about …

Rediscovering The Maryland Darter (Etheostoma Sellare), Tyler Russell Hern

Theses, Dissertations and Capstones

The Maryland darter has not been observed since 1988. Historic populations were located in Deer Creek, Swan Creek, and Gashey’s Run all of which occur in the lower Susquehanna drainage. At these locations, specimens were collected or observed at the lowest riffle of the stream. Some researchers suggest this may be a large river darter. The Conowingo Dam complicates surveying below the facility due to the rapid fluctuations in water levels caused by regulation for power production. Surveying efforts included trawling in the mainstem, and visual surveys in the mainstem, and searching/sampling all historically known locations of Etheostoma sellare. During …

Plesiosaur Body Shape And Its Impact On Hydrodynamic Properties, Courtney D. Richards

Theses, Dissertations and Capstones

Despite the variability of cross-sectional body shape within Plesiosauria, its impact on plesiosaur buoyancy and stability has never been investigated. This study focused on Tatenectes, Cryptoclidus, and Muraenosaurus due to their variable body morphologies. Reconstructions were created based on measurements and photographs from fossil remains. The ability of computer models, based upon the reconstructions, to reach equilibrium after submersion, sink via lung deflation, and recover from a lateral roll was tested. For the computer models, Muraenosaurus was replaced with Thalassomedon, which had a similar morphology. Cryptoclidus and Thalassomedon recovered from submersion faster than Tatenectes. All models achieved negative buoyancy with …

Phylogenetic Analysis Of Blacknose Dace (Rhinichthys) In West Virginia Streams, Samantha Taylor

Theses, Dissertations and Capstones

Blacknose dace (Rhinichthys) are one of the most common cyprinid fishes in eastern North America. They also have been a topic of debate for over 30 years because morphology-based systematics has failed to clearly define their taxa. Taxonomists classify the complex into two species and one subspecies: the eastern form, R. atratulus atratulus; and the western form R. obtusus obtusus, and southern form R. obtusus meleagris. This research uses the mitochondrial cytochrome b gene and genomic RAG 2 gene in a phylogenetic analysis to help clarify species relations according to differences between each current species. Maps have been created to …

Plastron Reduction And Associated Myology In Turtles, And Its Implications For Functional Morphology And Natural History, He Zhu

Theses, Dissertations and Capstones

This study seeks to understand the locomotor implications of plastron reduction in turtles through dissection, description and qualitative and quantitative analysis of muscle masses. A comparative study will be conducted between a turtle species with a reduced plastron (Chelydra serpentina) and a species with a full plastron (Trachemys scripta elegans) to gain a better understanding of how the reduced plastron in snapping turtles affects their myology and gait. Quantitative data on muscular mass and length will be obtained for statistical comparison between the two clades. Data collected will be used to make inferences on gait, stance and natural history.

Nest-Site Selection By Sharp-Shinned Hawks In Kentucky, Tyler Edmonson Rankin

Online Theses and Dissertations

Because Sharp-shinned Hawks (Accipiter striatus) are the most secretive of North America's forest-breeding raptors, little is known about their breeding biology, including their preferred nesting habitat. In 2009 and 2010, I searched 248 forest stands in Kentucky and found 11 nests, all located in pines (Pinus spp.). Nests were at a mean height of 18.6 ± 1.4 m in trees with a mean height of 23.7 m and mean dbh of 38.2 cm. Nests were in mixed coniferous/deciduous forests, with a mean canopy cover of 77.6%.

Rapid Reservoir Inundation Causes Complete Extirpation Of The Eastern Collared Lizard (Crotaphytus Collaris) Along The Shoreline Of Bull Shoals Lake In Northern Arkansas, S. E. Trauth

Journal of the Arkansas Academy of Science

The eastern collared lizard (Crotaphytus collaris) is a large saxicolous predatory lizard, which dwells in patchy, cedar glade environments characteristic of much of the Ozarks. The species can also be found in scattered populations along rocky shoreline habitats of large impoundment reservoirs of northern Arkansas. These lizards time their entrance into and exit from underground, overwintering retreats with decreasing and increasing ambient temperatures of the fall and spring months. During an average spring, several sustained days of warm temperatures from mid-March into April are the primary environmental cues for collared lizards to exit their shelters. Excessive winter/spring precipitation in the …
