Mercury Accumulation And Effects In The Brain Of Atlantic Sharpnose Sharks (Rhiszoprionodon Terranovae), Samantha L. Ehnert Jan 2017

Mercury Accumulation And Effects In The Brain Of Atlantic Sharpnose Sharks (Rhiszoprionodon Terranovae), Samantha L. Ehnert

UNF Graduate Theses and Dissertations

Sharks often bioaccumulate mercury (Hg) concentrations in their muscle to levels that threaten the health of human consumers. However, few published studies have examined if the high Hg levels seen in shark muscle also occur in the shark brain, or if Hg accumulation affects shark neurophysiology. Therefore, this study examined if shark brains accumulate significant levels of Hg, if Hg accumulation occurs in certain subcomponents of the brain, and if Hg accumulation is associated with oxidative stress effects on the shark central nervous system, with special focus on the Atlantic sharpnose shark (Rhizoprionodon terraenovae). Sharks were collected along …


Prosociality And Risk: How Risky Decision-Making In Young Adults Relates To Altruistic Tendencies, Empathic Concern, And Prosocial Peer Affiliation, Sarah J. Beard Jan 2017

Prosociality And Risk: How Risky Decision-Making In Young Adults Relates To Altruistic Tendencies, Empathic Concern, And Prosocial Peer Affiliation, Sarah J. Beard

UNF Graduate Theses and Dissertations

Adolescence involves an increase in risky decisions, such as reckless driving and illicit substance use, but prosocial characteristics and peer affiliation have yet to be investigated as protective factors. The present study assessed altruistic tendencies, prosocial peer affiliation (PPA), and empathic concern as predictors and moderators of risk-taking, including both self-reported health risks and riskiness in a behavioral task. Young adults from ages 20 to 25 (M = 22.55, SD = 1.38) completed a battery of behavioral tasks (including the Balloon Analogue Risk Task and the Dictator Game) and questionnaires on Amazon MTurk, measuring risk-taking (drunk driving, texting while …


Behavioral And Physiological Assessment Of Zoo-Housed Heterosexual Gorilla (Gorilla Gorilla Gorilla) Troops With Multiple Silverbacks, Kaylin S. Tennant Jan 2017

Behavioral And Physiological Assessment Of Zoo-Housed Heterosexual Gorilla (Gorilla Gorilla Gorilla) Troops With Multiple Silverbacks, Kaylin S. Tennant

UNF Graduate Theses and Dissertations

Based on recognized life history traits and ecology, zoos strive to house their gorillas (Gorilla gorilla gorilla) in mixed-sex groups with one mature male or silverback, multiple females, and their offspring. However, successful captive breeding programs and a nearly 50:50 birth sex ratio has created the need to house surplus males in solitary conditions or all-male groups. It is commonly believed that male western gorillas will not tolerate one another in the presence of females; however, multi-male, mixed-sex groups have been observed in the wild. For this reason, some zoos have begun experimenting with this scenario. At the …


Effects Of Group Selection With Yellow Birch (Betula Alleghaniensis) Retention On The Understory And Sapling Layer In Northern Hardwood Forests, Megan A. Petras O'Neil Jan 2017

Effects Of Group Selection With Yellow Birch (Betula Alleghaniensis) Retention On The Understory And Sapling Layer In Northern Hardwood Forests, Megan A. Petras O'Neil

Dissertations, Master's Theses and Master's Reports

Gap partitioning theory predicts that changes in microenvironment conditions found within a forest opening promote diversity in forest ecosystems. Under this theory we would expect to see variations in tree and understory diversity throughout and surrounding a forest opening. In order to test this theory, we examined manmade openings with legacy-tree retention in a northern hardwood forest located in the Upper Peninsula of Michigan. This work is part of an ongoing study that was started in 2003 with the creation of 49 openings centered on a reserve dominant or co-dominant yellow birch (Betula alleghaniensis Britt.). The primary objective of …


Impacts To Biodiversity And Ecosystem Services From Bioenergy Development: A Pan American Experience, Colin Phifer Jan 2017

Impacts To Biodiversity And Ecosystem Services From Bioenergy Development: A Pan American Experience, Colin Phifer

Dissertations, Master's Theses and Master's Reports

As part of a broader project that evaluated the social and ecological sustainability of bioenergy, I studied the effects of bioenergy associated land-use change and management on native bees and birds in two bioenergy-producing countries, the United States and Argentina. In Argentina, I worked in Entre Ríos province where eucalyptus (Eucalyptus spp.) plantations are being planted. These fast-growing trees are replacing pasture and annual crops, the current dominant land use. I surveyed for native bees and birds in pastures/annual crops and large-scale eucalyptus plantations, as well as mixed-use farms and native espinal savannas. Both birds and bees declined in …


Feasibility & Discovery Using Fox System To Generate Gain-Of-Function Mutations With Hybrid Poplars, James Rauschendorfer Jan 2017

Feasibility & Discovery Using Fox System To Generate Gain-Of-Function Mutations With Hybrid Poplars, James Rauschendorfer

Dissertations, Master's Theses and Master's Reports

The Full-length complementary DNA OvereXpression (FOX) system is an approach to generating gain-of-function (GF) plants predominantly used for studying Arabidopsis. This approach inserts T-DNAs containing random full-length complementary DNA (fl-cDNA) with upstream promoter and downstream terminator into the host plant genome. Studies using this method report the success generating overexpression populations with high mutation rates. We choose to investigate the feasibility and effectiveness of this method using poplars. We suspected using a succulent xylem specific fl-cDNAs library would enrich the transformant poplars with mutants affected in traits specific to woody tissue development. We observed a characteristically high mutation rate …

Dissertations, Master's Theses and Master's Reports

Quercus is important ecologically and economically because it provides food and habitat for wildlife, wood and paper products for humans. Oaks are endangered due to various factors like shifting climates, habitat loss, drought, pathogens and genetic swamping. Quercus georgiana (M.A. Curtis) is an endangered and restricted oak species which is remaining only in the southeastern part of the US. Efforts are required to conserve this endangered species from extinction. Conservation of this species can be done through these methods: ex-situ conservation (arboretum and botanical garden) and in-situ conservation strategies which protect the species in its natural habitat. For this conservation …


Assessing Growth, Yield, And Carbon Dynamics In Upper Great Lakes Jack Pine And Hybrid Poplar Managed For Biomass Production, Ashlee Baker Lehner Jan 2017

Assessing Growth, Yield, And Carbon Dynamics In Upper Great Lakes Jack Pine And Hybrid Poplar Managed For Biomass Production, Ashlee Baker Lehner

Dissertations, Master's Theses and Master's Reports

Woody biomass for use as coal-replacing bioenergy has garnered increasing interest as federal and local governments require larger portions of energy production to come from renewable sources. Woody biomass can be produced from dedicated plantations grown and harvested solely for biomass production, or non-dedicated sources such as harvest residues from traditional timber operations. The creation of site index curves for hybrid poplar were established from the Michigan Technological University Hybrid Poplar Network in the upper Great Lakes Region. These site index models are to be used for landowners to assess the predicted yield at established plantations, or possibly within spatial …

Characterization Of Ecological Water Stress In The U.S. Great Lakes Region Using A Geospatial Modeling Approach, Sara Alian Jan 2017

Characterization Of Ecological Water Stress In The U.S. Great Lakes Region Using A Geospatial Modeling Approach, Sara Alian

Dissertations, Master's Theses and Master's Reports

Anthropocentric water resources management affects aquatic habitats by changing streamflow regime. Understanding the impacts of water withdrawal from different sources and consumption by various economic sectors at different spatial and temporal scales is key to characterizing ecologically harmful streamflow disturbances. To this end, we developed a generic, integrative framework to characterize catchment scale water stress at annual and monthly time scales. The framework accounts for spatially cumulative consumptive and non-consumptive use impacts and associated changes in flow due to depletion and return flow along the stream network. Application of the framework to the U.S. Great Lakes Region indicates that a …

The main aim of this study was to investigate the effects of Portulaca oleracea extract on tumor formation in colon cancer stem cells and chemotherapy sensitivity. In addition, this study analyzed the genetic changes within the Notch signal transduction pathway associated with the effects of the extracts. Serum-free cultures of colon cancer cells (HT-29) and HT-29 stem cells were treated with the chemotherapeutic drug 5-FU to assess sensitivity. Injections of the stem cells were also given to BALB/c mice to confirm tumor growth and characteristics. In addition, the effect of different concentrations of P. oleracea extract was tested on the …


The Effects Of Early Pruning On The Near-Ground Branch Density Of Four Live Fencing Species, Aric Devens Jan 2017

The Effects Of Early Pruning On The Near-Ground Branch Density Of Four Live Fencing Species, Aric Devens

Dissertations, Master's Theses and Master's Reports

Crop losses in home gardens greatly impact the wellbeing of rural West African families. Herbivory by migratory or local livestock represents a significant source of crop loss. Live-fencing gardens with thorny hedges is a low-cost and sustainable strategy for reducing losses due to herbivory. However, guidance on the establishment of thorny hedges is inconsistent, poorly publicized, and often anecdotal. Therefore, this study evaluated the effects of three early pruning treatments on near-ground branch density of four thorny species: Vachellia nilotica, Senegalia laeta, Senegalia mellifera, and Prosopis juliflora. Physical measurements and photographic data indicated that after one growing season, V. …


Development Of Gene-Based Microsatellite Markers In Acer Saccharum Marsh., Monica Harmon Jan 2017

Development Of Gene-Based Microsatellite Markers In Acer Saccharum Marsh., Monica Harmon

Dissertations, Master's Theses and Master's Reports

Sugar maple (Acer saccharum Marsh) is an important ecological and economic resource. Despite its significance, there are few molecular genetic resources available to date. This study used previously developed EST libraries generated for sugar maple and other hardwood species to develop and characterize EST-SSRs in sugar maple and test their transferability to other Acer species. Out of 58 markers tested, 22 showed amplification in the expected size range. From these, 16 polymorphic markers were selected to test transferability and 13 of these showed amplification in at least one other Acer species.

Heterologous Expression And Purification Of Full-Length Human Polybromo-1 Protein, Sarah Hopson Jan 2017

Heterologous Expression And Purification Of Full-Length Human Polybromo-1 Protein, Sarah Hopson

Dissertations, Master's Theses and Master's Reports

Over the past decade, it has become apparent that the human polybromo-1 protein (BAF180) has a critical role in cancer. BAF180 is known to be a driver mutation in clear cell renal cell carcinoma, where it has been found to be mutated in approximately 40% of cases. Mutations have also been found in several other cancers, including intrahepatic cholangiocarcinomas and epithelioid sarcomas. BAF180 is the chromatin targeting subunit of the PBAF (Polybromo-associated BRG1-associated factor) chromatin remodeling complex, a role facilitated by its nine domains: six bromodomains, which recognize and bind to acetylated lysines on histones; two BAH (bromo-adjacent homology) domains, …


Neutral And Adaptive Genetic Variation In North American Hardwood Tree Species, Sudhir Khodwekar Jan 2017

Neutral And Adaptive Genetic Variation In North American Hardwood Tree Species, Sudhir Khodwekar

Dissertations, Master's Theses and Master's Reports

'Northern Hardwoods,’ are a characteristic composition of multiple tree species and a part of the rich and diverse northeastern forests. Hardwoods e.g. oaks (Quercus: Fagaceae and Sugar maple), serve as foundation species and offer ecological and economical gains to wildlife and humans. Most of the forest trees go through many biotic and abiotic stresses, for example climate change in their long life span. To overcome these threats and to adapt to changing conditions, tree species need to maintain variation especially in adaptive genes. Therefore, it is necessary to analyze genetic diversity within forest tree populations and take appropriate …


The Spatial Ecology Of Gray Wolves In The Upper Peninsula Of Michigan, 1994–2013, Shawn O'Neil Jan 2017

The Spatial Ecology Of Gray Wolves In The Upper Peninsula Of Michigan, 1994–2013, Shawn O'Neil

Dissertations, Master's Theses and Master's Reports

All natural processes are dynamic in space and time. Establishing the links between spatiotemporal patterns and ecological processes is critical for improving our understanding of natural systems. Empirical data representing wildlife populations is accumulating and increasingly involves spatiotemporal components. Wildlife monitoring programs for threatened, endangered, or other species of interest often involve radio-tracking of a sample of individual animals combined with census data. Such data are valuable both for conservation and management of populations and for testing ecological theories about species distribution and what influences patterns over time. We used 20 years of radio telemetry and snow tracking data to …


Blossomsttm Hub – An Online Tool For Designing Sttm Vectors And Visualizing Phenotypic Changes Of Sttm Transgenic Lines, Avinash Subramanian Jan 2017

Blossomsttm Hub – An Online Tool For Designing Sttm Vectors And Visualizing Phenotypic Changes Of Sttm Transgenic Lines, Avinash Subramanian

Dissertations, Master's Theses and Master's Reports

Small RNAs including microRNAs (miRNAs) and short interfering RNAs (siRNAs) are widely present in plants. They are transcribed from non-coding small RNA genes and then play as regulators to modulate the levels of messenger RNAs (mRNAs) of protein-coding genes via sequence pairings. This is because a paired complementary double sequence helix structure can trigger mRNA degradation or interfere with mRNA translation. Short Tandem Target Mimic (STTM) is a recently developed technology that can be used to produce a complementary sequence to a miRNA and destroy it or reduce the expression level of this miRNA via the formation of paired double-strand …


Dynamics Of Wild Red Raspberry (Rubus Idaeus L.) And The Influence On Tree Regeneration Within Silvicultural Openings In A Northern Hardwood Stand, Matthew J. Widen Jan 2017

Dynamics Of Wild Red Raspberry (Rubus Idaeus L.) And The Influence On Tree Regeneration Within Silvicultural Openings In A Northern Hardwood Stand, Matthew J. Widen

Dissertations, Master's Theses and Master's Reports

Previous studies have investigated how the abundance of raspberries (Rubus idaeus L.) impacts tree regeneration, but few have linked these impacts to location within canopy openings with a legacy tree. To fill this knowledge gap, we investigated the presence, abundance, and location of raspberries within openings containing legacy trees and the resulting impacts on tree regeneration. During the winter of 2003, 49 openings were created of three sizes: small, medium, large and 20 reference single-tree selection sites in a northern hardwood stand in Ford Forest near Alberta, Michigan. Tree regeneration and vegetative species cover were recorded in 2005 and …


Methane Fluxes And Porewater Dissolved Organic Carbon Dynamics From Different Peatlands Types In The Pastaza-Marañon Basin Of The Peruvian Amazon., Jhon Del Aguila-Pasquel Jan 2017

Methane Fluxes And Porewater Dissolved Organic Carbon Dynamics From Different Peatlands Types In The Pastaza-Marañon Basin Of The Peruvian Amazon., Jhon Del Aguila-Pasquel

Dissertations, Master's Theses and Master's Reports

Relevant components of the carbon budget such as methane fluxes and porewater dissolved organic carbon (DOC) are poorly characterized in the Peruvian Pastaza Marañon basin (PMB). PMB is associated with a tropospheric hotspot for methane and therefore it may represent a significant methane source. We aimed to quantify the magnitude of CH4 fluxes and porewater DOC; and to determine their predictors across different peatland types in the PMB (open peatland, palm swamp, and pole forest). The study was conducted in two peatland sites covering the three main vegetation types in PMB. We collected gas and water samples using chamber-based …

Effects Of Post-Fire Salvage Logging On Compaction, Infiltration, Water Repellency, And Sediment Yield And The Effectiveness Of Subsoiling On Skid Trails, Iskender Demirtas

Dissertations, Master's Theses and Master's Reports

Post-fire salvage logging operations can induce environmental problems. This study assessed the effects of different disturbances from post-fire salvage logging on soil bulk density, water repellency, field saturated hydraulic conductivity (Kfs), ground cover, and sediment yields after the 2013 Rim Fire in California. Hillslope plots were installed in three locations (Sawmill, lower Femmons, and upper Femmons). The plot-scale disturbances were burned and untrafficked (low and high slope controls and logged only with no traffic), or burned and trafficked (few and many pass skid trails). Additional measurements were made in nearby areas that included the plot-scale disturbances as well as feller …


Differential Gene Expression Analysis Of Metolachlor Treated Human Liver Cells By Microarray, Navinder Paul Kaur Brar Jan 2017

Differential Gene Expression Analysis Of Metolachlor Treated Human Liver Cells By Microarray, Navinder Paul Kaur Brar

Dissertations and Theses @ UNI

Metolachlor is one of the most common pre-emergent pesticides used by Iowa farmers. It is used to control broadleaf weeds and grasses in the fields of corn and soybean. It is a frequent contaminant of groundwater and surface water due to runoff after application. It has been shown to inhibit protein and chlorophyll synthesis in plant cells, but its effect on mammalian cells has not been consistently conclusive. As metolachlor and other herbicides have been shown to be associated with harmful health effects in non-target organisms it is very important to determine a mechanism of action on non-target cells, especially …


In Silico Screening Of Chalcones Against Epstein-Barr Nuclear Antigen 1 Protein In Epstein-Barr Virus (Ebv), Nitchakan Darai Jan 2017

In Silico Screening Of Chalcones Against Epstein-Barr Nuclear Antigen 1 Protein In Epstein-Barr Virus (Ebv), Nitchakan Darai

Chulalongkorn University Theses and Dissertations (Chula ETD)

Epstein-Barr Nuclear Antigen 1 (EBNA1), a crucial protein encoded by the Epstein-Barr virus (EBV), plays an important role in the replication and transcriptional regulator of EBV virus latent gene expression. Therefore, it is associated with several diseases especially human malignancies. The previous studies have demonstrated that chalcone derivatives can potentially inhibit the EBV virus. In this study, a series of designed chalcones were in silico screened toward EBNA1 using molecular docking. The docking results show that the interaction energies of 3a, 3b, 3d, 4g and 4h are better than those of the known anti-EBV agents, 1335528, 2122620 and 4-hydroxyderricin. The …


The Maculoprotective Effect Of A Thiol Antioxidant In Retinal Degeneration Models, Hsiu-Jen Wang Jan 2017

The Maculoprotective Effect Of A Thiol Antioxidant In Retinal Degeneration Models, Hsiu-Jen Wang

Doctoral Dissertations

"Age-related macular degeneration (AMD) is a leading cause of irreversible blindness among adults, age 60 and older, in developed countries. While oxidative stress is implicated in the pathogenesis of AMD, clinical studies have shown that dietary antioxidants can delay progression of AMD. Currently, there is no FDA-approved treatment for AMD. Therefore, we hypothesized that N-acetylcysteine amide (NACA), a thiol antioxidant, would protect retinal pigment epithelium and impede the progression of retinal degeneration. The goal of this work was to evaluate the efficacy of NACA in preventing retinal pigment epithelial cell and photoreceptor death in AMD models. To achieve this, we …


Canine Emotions As Seen Through Human Social Cognition, Miiamaaria V. Kujala Jan 2017

Canine Emotions As Seen Through Human Social Cognition, Miiamaaria V. Kujala

Animal Sentience

It is not possible to demonstrate that dogs (Canis familiaris) feel emotions, but the same is true for all other species, including our own. The issue must therefore be approached indirectly, using premises similar to those used with humans. Recent methodological advances in canine research reveal what dogs experience and what they derive from the emotions perceptible in others. Dogs attend to social cues, they respond appropriately to the valence of human and dog facial expressions and vocalizations of emotion, and their limbic reward regions respond to the odor of their caretakers. They behave differently according to the …


Dogs Consciously Experience Emotions: The Question Is, Which?, Ralph Adolphs Jan 2017

Dogs Consciously Experience Emotions: The Question Is, Which?, Ralph Adolphs

Animal Sentience

I discuss three themes related to Kujala’s target article. First, the wealth of emerging data on cognitive studies in dogs will surely show that dogs have a very rich repertoire of cognitive processes, for most of which we find homologues in humans. Second, understanding the internal states that mediate social behaviors, such as emotions, requires us to consider both a dog’s behaviors with other dogs, and the emergence of new behavioral patterns in interaction with humans. Third, all of this will certainly narrow the range of justifications for denying that dogs have subjective experiences of emotions.


The Study Of Emotion In Animals, Thomas R. Zentall Jan 2017

The Study Of Emotion In Animals, Thomas R. Zentall

Animal Sentience

The responsiveness of dogs to humans encourages us to attribute human-like emotions to them. Indirect evidence for emotions in other animals can be obtained but one must be careful to find means of distinguishing what we believe to be evidence for such emotions from simpler mechanisms. For example, is a dog’s growl an indication of anger, fear, or possibly an unemotional defense of territory? By carefully designing experiments, we may be able to rule out alternative accounts and show better evidence for underlying emotions.


Emotion In Dogs: Translational And Transformative Aspects, Silvan R. Urfer Jan 2017

Emotion In Dogs: Translational And Transformative Aspects, Silvan R. Urfer

Animal Sentience

Kujala (2017) provides an excellent overview of most aspects of emotion in dogs; however, she does not cover a few fields of research that I think are also relevant to the topic. In this commentary, I discuss the current state of our knowledge regarding cognitive decline and behavioral disorders in dogs as potential models for human neurodegenerative disease and mental illness; how emotion and cognition in dogs interact with sex, gonadectomy, and sexual behavior; as well as the transformative potential of functional MRI imaging of the conscious dog brain in the study of comparative neurophysiology.


Direct Perception Of Animal Mind, Paul Morris Jan 2017

Direct Perception Of Animal Mind, Paul Morris

Animal Sentience

Kujala’s (2017) target article is ostensibly focused on how everyday folk (fail to) make sense of canine emotions. However, the theories outlined in the article apply to making sense of all aspects of the mentality of both human and non-human animals. The target article neglects the fundamental arguments surrounding the problem of other minds. I explore the relevant arguments and briefly review approaches suggesting that our everyday-life sense that both human and non-human animals are thinking, feeling, emotional beings has a secure epistemological basis.


Canine Emotions And The Bond Between Humans And Dogs, Robert G. Franklin Jr. Jan 2017

Canine Emotions And The Bond Between Humans And Dogs, Robert G. Franklin Jr.

Animal Sentience

I explore how the findings reviewed by Kujala (2017) influence our understanding of the human-dog bond. The special social cognitive abilities of dogs may be unique among animal species, probably influenced by the circumstances surrounding canine domestication. The bond has influenced animal welfare policies, giving dogs a privileged place among animals. To determine what protections other species should have in a rational animal welfare policy, more research is needed on whether other species have similar social cognitive abilities.
