Effects Of Exotic Invasive Vegetation On Breeding Birds Along The North Chickamauga Creek, Shannon Elaine Hatmaker

Masters Theses and Doctoral Dissertations

The invasion of exotic plants into riparian areas of southeastern United States is a conservation concern not only for native plant communities, but also for wildlife. Breeding bird community structure could be particularly affected by such invasions and subsequent habitat changes as birds respond quickly to changes in habitat resources. During the 2007 breeding season, bird communities were surveyed using the line transect census method at four sites along the North Chickamauga Creek in Hamilton County, Tennessee. Two of the sites were regarded as being highly invaded by exotic understory plant species, while the other two sites remain relatively free …

Identification Of Two Distinct Glutaminyl Cyclase Isoforms In Drosophila Melanogaster, Amanda Thigpen Parker

Dissertations

Sequence analyses revealed two putative glutaminyl cyclase genes in Drosophila melanogaster with greater than 60% amino acid sequence identity to previously identified glutaminyl cyclase in humans. Expression, purification, and characterization of both putative proteins revealed two enzymatically active glutaminyl cyclase enzymes. Comparison of the Drosophila melanogaster glutaminyl cyclase enzymes to the published human glutaminyl cyclase revealed the enzymes were very similar. The Km values obtained were identical to those of human glutaminyl cyclase for three different substrates tested. However, the Drosophila glutaminyl cyclases demonstrated lower turnover numbers. Both Drosophila glutaminyl cyclase isoforms were inhibited by imidazole, imidazole derivatives, and metal …

An Evolutionary Expressed Sequence Tag Analysis Of Drosophila Spermatheca Genes, Adrianne Prokupek, Federico G. Hoffmann, Seong-Il Eyun, Etsuko N. Moriyama, Min Zhou, Lawrence G. Harshman

Papers in Genetics

This study investigates genes enriched for expression in the spermatheca, the long-term sperm storage organ (SSO) of female Drosophila. SSO genes are likely to play an important role in processes of sexual selection such as sperm competition and cryptic female choice. Although there is keen interest in the mechanisms of sexual selection at the molecular level, very little is known about the female genes that are involved. In the present study, a high proportion of genes enriched for expression in the spermatheca are evolving rapidly. Most of the rapidly evolving genes are proteases and genes of unknown function that …

Diet Influences Mate Choice Selectivity In Adult Female Wolf Spiders, Eileen Hebets, Jennifer Wesson, Paul S. Shamble

Eileen Hebets Publications

Most studies of female choice have assumed that mating preferences are shared within a population or species. However, variation both within and among females exists in natural populations, and foraging history is among the many ways in which females may vary. Here, we used diet manipulations in an effort to understand how foraging history influences female mate choice. Immature Schizocosa wolf spiders collected from a mixed population of brush-legged and non-ornamented males were reared in the laboratory on two diets that varied in both quality and quantity (low/high diet). For low- and high-diet individuals, we recorded data on rates of …

The Aryl Hydrocarbon Receptor Binds To E2f1 And Inhibits E2f1-Induced Apoptosis., Jennifer L Marlowe, Yunxia Fan, Xiaoqing Chang, Li Peng, Erik S Knudsen, Ying Xia, Alvaro Puga

Kimmel Cancer Center Faculty Papers

Cellular stress by DNA damage induces checkpoint kinase-2 (CHK2)-mediated phosphorylation and stabilization of the E2F1 transcription factor, leading to induction of apoptosis by activation of a subset of proapoptotic E2F1 target genes, including Apaf1 and p73. This report characterizes an interaction between the aryl hydrocarbon (Ah) receptor (AHR), a ligand-activated transcription factor, and E2F1 that results in the attenuation of E2F1-mediated apoptosis. In Ahr(-/-) fibroblasts stably transfected with a doxycycline-regulated AHR expression vector, inhibition of AHR expression causes a significant elevation of oxidative stress, gammaH2A.X histone phosphorylation, and E2F1-dependent apoptosis, which can be blocked by small interfering RNA-mediated knockdown of …

Recent Advances In The Management Of Hypertension, Mansour M. Al-Nozha, Mohamed Z. Khalil

Saudi Medical Journal

Hypertension is a worldwide prevalent disease that leads to considerable morbidity and mortality. While its underlying basis of genetics and pathology as well as its complications are universally agreed upon, management of hypertension remains to be controversial. In this article, we will present clear evidence of the recent advances in the management of hypertension that include newer therapeutic agents replacing old strategies. Moreover, a suggested approach that is evidence based is provided to help in establishing agreement in line of therapy.

Capillary Electrophoresis-Based Immunoassays: Principles & Quantitative Applications, Annette C Moser, David S. Hage

David Hage Publications

The use of capillary electrophoresis as a tool to conduct immunoassays has been an area of increasing interest over the last decade. This approach combines the efficiency, small sample requirements, and relatively high speed of CE with the selectivity of antibodies as binding agents. This review examines the various assay formats and detection modes that have been reported for these assays, along with some representative applications. Most CE immunoassays in the past have employed homogeneous methods in which the sample and reagents are allowed to react in solution. These homogeneous methods have been conducted as both competitive binding immunoassays and …

Pasteurellosis Transmission Risks Between Domestic And Wild Sheep, Michael W. Miller, Donald P. Knowles, Marie S. Bulgin, Billy R. Clay, Walter E. Cook, Subramaniam Srikumaran, A. David Scarfe, Dale Layfield

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Disease has contributed significantly to the decline of bighorn sheep (Ovis Canadensis) populations throughout much of western North America, decreasing many native herds to less than 10% of their historical size and imperiling some populations and subspecies (Valdez and Krausman 1999). According to historical accounts (e.g., Grinnell 1928; Honess and Frost 1942; Shillinger 1937; Warren 1910), epidemics in some locations coincided with the advent of domestic livestock grazing in bighorn ranges, suggesting that novel pathogens may have been introduced into some bighorn populations beginning in the 1800s.

Species Of Coccidia (Apicomplexa: Eimeriidae) In Shrews From Alaska, U.S.A., And Northeastern Siberia, Russia, With Description Of Two New Species, A. J. Lynch, Donald W. Duszynski

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Fecal samples (n = 636) from 10 species of shrews collected in Alaska (n = 540) and northeastern Siberia (n = 96) were examined for the presence of coccidia (Apicomplexa: Eimeriidae). Five distinct oocyst morphotypes were observed. Three types were consistent with oocysts of previously recognized coccidia species from other shrew hosts. These were Eimeria inyoni, E. vagrantis, and Isospora brevicauda, originally described from the inyo shrew (Sorex tenellus), dusky shrew (S. monticolus), and northern short-tailed shrew (Blarina brevicauda), respectively. We found 5 new host records for E. …

Optical And Electrochemical Molecular And Nanoscale Sensors For The Selective Detection Of Organophosphorus Based Pesticides, Chandrima De

Masters Theses

Organophosphorus based pesticides are highly toxic and represent serious environmental concerns. These compounds tend to easily enter ground water and cause drastic pollution. The toxicity levels of the organophosphorus pesticides however are based on their structures, and hence methods for their selective detection are in high demand. The creation of new materials for sensing and actuation requires careful manipulation of the responsive units required to control analyte selectivity. We have successfully designed and synthesized a molecular sensor based on the family of stilbenes that not only can detect organophosphorus pesticides, but also distinguish between them. Four different pesticides have been …

Simulating A Smartboard By Real-Time Gesture Detection In Lecture Videos, Feng Wang, Chong-Wah Ngo, Ting-Chuen Pong

Research Collection School Of Computing and Information Systems

Gesture plays an important role for recognizing lecture activities in video content analysis. In this paper, we propose a real-time gesture detection algorithm by integrating cues from visual, speech and electronic slides. In contrast to the conventional "complete gesture" recognition, we emphasize detection by the prediction from "incomplete gesture". Specifically, intentional gestures are predicted by the modified hidden Markov model (HMM) which can recognize incomplete gestures before the whole gesture paths are observed. The multimodal correspondence between speech and gesture is exploited to increase the accuracy and responsiveness of gesture detection. In lecture presentation, this algorithm enables the on-the-fly editing …

Vibration Causes Acute Vascular Injury In A Two-Step Process: Vasoconstriction And Vacuole Disruption, Sandya R. Govindaraju, James L. W. Bain, Thomas J. Eddinger, Danny A. Riley

Biological Sciences Faculty Research and Publications

Hand–arm vibration syndrome is a vasospastic and neurodegenerative occupational disease. In the current study, the mechanism of vibration- induced vascular smooth muscle cell (SMC) injury was examined in a rat-tail vibration model. Tails of male Sprague Dawley rats were vibrated continuously for 4 hr at 60 Hz, 49 m/s2 with or without general anesthesia. Ventral tail arteries were aldehyde fixed and embedded in epoxy resin to enable morphological analysis. Vibration without anesthesia caused vasoconstriction and vacuoles in the SMC. Anesthetizing rats during vibration prevented vasoconstriction and vacuole formation. Exposing tail arteries in situ to 1 mM norepinephrine (NE) for 15 …

Fish Distributions And Nutrient Cycling In Streams: Can Fish Create Biogeochemical Hotspots, Peter B. Mcintyre, Alexander S. Flecker, Michael J. Vanni, James M. Hood, Brad W. Taylor, Steven A. Thomas

Dartmouth Scholarship

Rates of biogeochemical processes often vary widely in space and time, and characterizing this variation is critical for understanding ecosystem functioning. In streams, spatial hotspots of nutrient transformations are generally attributed to physical and microbial processes. Here we examine the potential for heterogeneous distributions of fish to generate hotspots of nutrient recycling. We measured nitrogen (N) and phosphorus (P) excretion rates of 47 species of fish in an N-limited Neotropical stream, and we combined these data with population densities in each of 49 stream channel units to estimate unit- and reach-scale nutrient recycling. Species varied widely in rates of N …

Decline In A Dominant Invertebrate Species Contributes To Altered Carbon Cycling In A Low-Diversity Soil Ecosystem, Byron J. Adams, J. E. Barrett, Ross A. Virginia, Diana H. Wall

Faculty Publications

Low-diversity ecosystems cover large portions of the Earth's land surface, yet studies of climate change on ecosystem functioning typically focus on temperate ecosystems, where diversity is high and the effects of individual species on ecosystem functioning are difficult to determine. We show that a climate-induced decline of an invertebrate species in a low-diversity ecosystem could contribute to significant changes in carbon © cycling. Recent climate variability in the McMurdo Dry Valleys of Antarctica is associated with changes in hydrology, biological productivity, and community composition of terrestrial and aquatic ecosystems. One of the greatest changes documented in the dry valleys is …

Male Out-Migration And The Women Left Behind: A Case Study Of A Small Farming Community In Southeastern Mexico, Jamie P. Mcevoy

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Until recently, rural households in southeastern Mexico have survived on subsistence and chili farming. But over the last decade, male out-migration to the United States has also become a popular livelihood strategy. This case study used data from semi-structured qualitative interviews to assess the effects of male out-migration on women's lives in three areas: households' financial and material situation, issues of infidelity and women's vulnerability to abandonment, and the gendered division of labor.

Overall, this study found that male out-migration had both positive and negative effects on the women left behind. First, the financial outcomes of migration were mixed. A …
