A Survey Of Ionoregulatory Responses To Extended Exercise And Acute Hypoxia In Freshwater Amazonian And Southern Ontarian Teleosts: Investigating The Osmorespiratory Compromise, Lisa M. Robertson Msc
Open Access Dissertations and Theses
The osmorespiratory compromise is the trade-off between high gill permeability for oxygen uptake and low gill permeability for conservation of ions in fish. The fundamental purpose of this study was to examine facets of the osmorespiratory compromise in freshwater fish under conditions of extended exercise and acute hypoxia, in light of previous research identifying very different gill morphometric and ionoregulatory modifications in the hypoxia-tolerant Amazonian oscar (Astronotus ocellatus) and the hypoxia-intolerant rainbow trout (Oncorhynchus mykiss). A technique using [3H]polyethylene-4000 ([3H]PEG-4000) for branchial paracellular permeability measurement was developed, and then applied to investigate the osmorespiratory compromise during ...

An Investigation Of The Look Away Behavior In Domestic Dogs, Sarah Scott
Undergraduate Review
The unique phylogenetic and ontogenetic history of domestic dogs has had an effect on the way they communicate with one another. Research suggests that domestic dogs’ ability to communicate through visual signals may vary by breed (Goodwin, Bradshaw, & Wickens 1997; Kerswell, Bennet, Butler, & Hemsworth 2009). In the current study, we investigate the effect of a visual communication signal, the look away, observed in both domestic dogs and their ancestor, the wolf, in order to examine whether or not domesticated dogs respond to this visual signal. Research indicates that domestic dogs respond appropriately to artificial dog models (Leaver & Reimchen, 2008). Therefore, we allowed ...

Exploring The Sulfide Tolerance Of Ectosymbiotic Niphargus Amphipods From The Frasassi Caves, Central Italy, Jan Bauermeister, Karoline Assig, Sharmishtha Dattagupta
International Journal of Speleology
Two species of the crustacean amphipod genus Niphargus inhabit the sulfidic groundwaters of the Frasassi caves in central Italy, and both harbor filamentous, sulfide-oxidizing Thiothrix ectosymbionts. As sulfide is toxic to most aerobic organisms, it appeared possible that the ectosymbionts could help their Niphargus hosts with detoxification processes. In this study, mortality due to sulfide was compared between Niphargus individuals with ectosymbionts and individuals whose ectosymbionts had been killed by antibiotic treatment. Both Frasassi-dwelling Niphargus species revealed exceptionally high tolerances to sulfide compared to other amphipod species studied so far. Niphargus individuals without viable ectosymbionts tolerated sulfide levels exceeding those ...

Characterization And Potential Utility Of Porcine Trophoblast-Derived Stem-Like Cells, Edison A. Suasnavas
All Graduate Theses and Dissertations
In mammals, the trophoblast lineage of the embryo is specified before implantation. It is restricted to become the fetal portion of the placenta. We have isolated and cultured trophoblast-derived cells from day 10 and day 13 porcine embryos. These cells demonstrate morphological and biological characteristics that make them unique. We have demonstrated that these cells can grow in vitro in a defined, serum-replacement medium for over a year without showing any signs of senescence. Trophoblast-derived cells placed into serum-containing medium, however, rapidly senesce and fail to proliferate. Gene expression analysis by RT-PCR and Fluidigm analysis of cells in culture from ...
Cougar Predation Behavior In North-Central Utah, Dustin L. Mitchell Utah State University
Cougar Predation Behavior In North-Central Utah, Dustin L. Mitchell
All Graduate Theses and Dissertations
Cougar (Puma concolor) predation has been identified as being one of several factors contributing to the decline of mule deer (Odocoileus hemionus) throughout the Western United States. In order to better understand how these elusive felines utilize their surroundings and prey, I examined and analyzed cougar predation behavior in North-Central Utah, using global positioning systems (GPS) data from 2002-2010. Twenty-three cougars were fitted with GPS collars and monitored for prey caching behavior. In total 775 potential cache sites were visited and 546 prey remains found. Mule deer comprised the majority of prey at cougar cache sites, but 11 other species ...
Comparison Of Topographic Surveying Techniques In Streams, Sara G. Bangen Utah State University
Comparison Of Topographic Surveying Techniques In Streams, Sara G. Bangen
All Graduate Theses and Dissertations
Fine-scale resolution digital elevation models (DEMs) created from data collected using high precision instruments have become ubiquitous in fluvial geomorphology. They permit a diverse range of spatially explicit analyses including hydraulic modeling, habitat modeling and geomorphic change detection. Yet, the intercomparison of survey technologies across a diverse range of wadeable stream habitats has not yet been examined. Additionally, we lack an understanding regarding the precision of DEMs derived from ground-based surveys conducted by different, and inherently subjective, observers. This thesis addresses current knowledge gaps with the objectives i) to intercompare survey techniques for characterizing instream topography, and ii) to characterize ...

The Effect Of Medetomidine On The Burying Speed Of Corbicula Fluminea, Andrew K. Schmucker '14
Student Publications
A new anti-fouling drug, medetomidine, was tested to determine if it reduced the burying speed of a freshwater alien-invasive bivalve species, Corbicula fluminea. Corbicula are known to damage underwater structures and must be managed with chemical paints. The burying speeds of Corbicula were measured both before and after exposure to two different concentrations of medetomidine. The burying speed of Corbicula before exposure to a 1x10-6 M medetomidine solution was not significantly different from the burying speed after exposure (t=.55, df=21, p=.588). The burying speed of Corbicula was significantly slower after exposure to a 1x10-5 M ...

Impact Of Direct-Fed Microbials On Nutrient Utilization In Beef Cattle, Nicole Kenney
Theses and Dissertations--Animal and Food Sciences
The impact of lactate producing direct-fed microbial (DFM) on growth performance and rumen fermentation in beef cattle was explored in four studies. Experiment 1 studied the interaction between DFM and degradable intake protein (DIP) supply in receiving cattle. No differences (P≥0.06) in intake, morbidity, or immune response were observed; however, during the first 28 d gain and efficiency responses to DFM were dependent on DIP (DIP×DFM P≤0.05). Experiment 2 showed that in vitro gas production and select endpoint metabolites differed (P≤0.04) with DFM application. Experiment 3 compared lactate producing DFM to a lactate ...

Avian pathogenic Escherichia coli (APEC) causes morbidity in chickens and exhibits zoonotic potential. Understanding host transcriptional responses to infection aids the understanding of protective mechanisms and serves to inform future colibacillosis control strategies. Transcriptomes of spleen and peripheral blood leukocytes (PBLs) of the same individual birds in response to APEC infection were compared to identify common response patterns and connecting pathways. More than 100 genes in three contrasts examining pathology and infection status were significantly differentially expressed in both tissues and similarly regulated. Tissue-specific differences in catalytic activity, however, appear between birds with mild and severe pathology responses. Early expression ...

Assessment Of Sea Lice Infestations On Wild Fishes Of Cobscook Bay, Alexander Jensen
Honors College
Sea lice are ectoparasitic copepods on fishes and can negatively impact aquaculture operations. Little work on sea lice, specifically Lepeophtheirus salmonis and Caligus elongatus, has occurred in the northwest Atlantic. This project characterized sea lice infestations on wild fishes in Cobscook Bay during 2012. Trawling, seine netting, and fyke netting occurred from March to November. Netting sites were selected to sample the bay’s three regions: Outer, Central, and Inner Bay. Visual examinations of fish were used to identify wild hosts and characterize sea lice life stage abundances, attachment locations, and infection prevalence and intensity. DNA sequencing was used to ...

Avian pathogenic Escherichia coli (APEC) leads to economic losses in poultry production and is also a threat to human health. The goal of this study was to characterize the chicken spleen transcriptome and to identify candidate genes for response and resistance to APEC infection using Solexa sequencing. We obtained 14422935, 14104324, and 14954692 Solexa read pairs for non-challenged (NC), challenged-mild pathology (MD), and challenged-severe pathology (SV), respectively. A total of 148197 contigs and 98461 unigenes were assembled, of which 134949 contigs and 91890 unigenes match the chicken genome. In total, 12272 annotated unigenes take part in biological processes (11664), cellular ...

The objective of this study was to develop a validated, transient, chemically induced lameness model in sows using subjective and objective lameness detection tools. Experiment 1 determined an effective joint injection technique based on volume and placement of dye using feet collected from 9 finisher pigs and 10 multiparity cull sow carcasses. Experiment 2 confirmed the injection technique in live animals and produced a transient clinical lameness in 4 anesthetized sows injected with amphotericin B (15 mg/mL) in the distal interphalangeal joints of the claw. Clinical lameness was assessed by a categorical lameness scoring system, and a postmortem visual ...
