The Effects Of Prenatal Exposure Of Valproic Acid On Cranial Nerve Nuclei: A Rat Model For An Autistic Phenotype, Shannon Pickup May 2009

The Effects Of Prenatal Exposure Of Valproic Acid On Cranial Nerve Nuclei: A Rat Model For An Autistic Phenotype, Shannon Pickup

Renée Crown University Honors Thesis Projects - All

Autistic spectrum disorder is a term referring to five pervasive developmental disorders characterized by impairment in social interaction, deficits in verbal and non-verbal communication and stereotyped repetitive behaviors and interests. The underlying brain injury that leads to autism is also unknown. The cause is also unknown but appears to be a combination of genetic and environmental factors. A study on prenatal thalidomide exposure found patients exposure on days 20-24 of gestation lead to a 1/3 rate of autism, a huge increase from the 1/150 rate of the general population. The thalidomide data suggests the initial injury leading to autism occurs …


United States Food Law Update: Pasteurized Almonds And Country Of Origin Labeling, A. Bryan Endres May 2009

United States Food Law Update: Pasteurized Almonds And Country Of Origin Labeling, A. Bryan Endres

Journal of Food Law & Policy

The last six months of 2008 found the nation occupied with a heated presidential election campaign and the transition to a new party's control of the executive branch. The outgoing president, as is often the case in the waning months of an administration's time in office, attempted to finalize several policy initiatives. This version of the Food Law Update will discuss two major developments with significant long-term impact on the law of food: the implementation of mandatory country of origin labeling (COOL) for most unprocessed agricultural commodities; and the increasing use of the United States Department of Agriculture's (USDA) Agricultural …


Effects Of Targeted Grazing And Prescribed Burning On Fire Behavior And Community Dynamics Of A Cheatgrass (Bromus Tectorum)-Dominated Landscape, Joel M. Diamond May 2009

Effects Of Targeted Grazing And Prescribed Burning On Fire Behavior And Community Dynamics Of A Cheatgrass (Bromus Tectorum)-Dominated Landscape, Joel M. Diamond

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Studies were conducted to determine the effectiveness of using targeted grazing and prescribed burning as tools to reduce fire hazards and cheatgrass (Bromus tectorum) dominance on rangelands in the northern Great Basin. A field study, with four grazing-burning treatments (graze and no-burn, graze and burn, no-graze and burn, and no-graze and no-burn), was conducted on a B. tectorum-dominated site near McDermitt, Nevada from 2005-2007. Cattle removed 80-90% of standing biomass in grazed plots in May 2005 and 2006 when B. tectorum was in the boot (phenological) stage. Grazed and ungrazed plots were burned in October 2005 and …


Consequences Of Vegetation Change On The Dynamics Of Labile Organic Matter And Soil Nitrogen Cycling In A Semiarid Ecosystem, Toby D. Hooker May 2009

Consequences Of Vegetation Change On The Dynamics Of Labile Organic Matter And Soil Nitrogen Cycling In A Semiarid Ecosystem, Toby D. Hooker

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Sagebrush-dominated ecosystems are being transformed by wildfire, rangeland improvement techniques, and exotic plant invasions. These disturbances have substantial effects on the composition and structure of native vegetation, but the effects on ecosystem C and N dynamics are poorly understood. To examine whether differences in dominant vegetation affect the quantity and quality of plant organic matter inputs to soil, ecosystem C and N pools and rates of plant turnover were compared among historically grazed Wyoming big sagebrush, introduced perennial crested wheatgrass, and invasive annual cheatgrass communities. Since low soil moisture during the summer may inhibit the microbial colonization of plant detrital …


Application Of Electrified Fladry To Decrease Risk Of Livestock Depredation By Wolves (Canis Lupus), Nathan J. Lance May 2009

Application Of Electrified Fladry To Decrease Risk Of Livestock Depredation By Wolves (Canis Lupus), Nathan J. Lance

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Wolf (Canis lupus) predation on livestock can cause economic and emotional hardships for livestock producers, complicating the balance of wolf conservation with other human interests. New management tools that decrease risk of predation may offer additional flexibility or efficiency for both livestock producers and management agencies. I examined 1) the efficacy of electrified fladry compared to fladry at protecting a food source from wolves in captivity, 2) the efficacy of electrified fladry for reducing wolf use of pastures and preventing depredations, and 3) the applicability of electrified-fladry. In captivity I tested the reaction from 15 groups (46 wolves) …


Taste Sensitivity To 6-N-Propylthiouracil (Prop) As A Biological Marker For Vulnerability To Stress In Mothers And Children, Deann Jones May 2009

Taste Sensitivity To 6-N-Propylthiouracil (Prop) As A Biological Marker For Vulnerability To Stress In Mothers And Children, Deann Jones

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Some people are genetically more vulnerable to stress than others, leading them towards poorer outcomes following stressful events. Mothers' vulnerability to stress may, in turn, influence their children, leading their children towards poor outcomes as well. A biological marker of vulnerability to stress may indicate mothers who are at greater risk for experiencing parenting stress, depression, and less support of the infant's emotional development, and infants who are at greater risk for development of poor emotion regulation and behavior problems. Taste sensitivity to propylthiouracil (PROP) is proposed as a biological marker of stress vulnerability in mothers and children. This research …


Microbial Growth Inhibition And Decomposition Of Milk Mineral And Sodium Tripolyphosphate Added To Media Or Fresh Ground Beef, Rossarin Tansawat May 2009

Microbial Growth Inhibition And Decomposition Of Milk Mineral And Sodium Tripolyphosphate Added To Media Or Fresh Ground Beef, Rossarin Tansawat

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Milk mineral (MM) is a type II antioxidant (metal chelator) that can bind iron and prevent iron catalysis of lipid oxidation. Thus, MM might have microbial growth inhibition effects on iron-dependent bacteria. Objective 1 was to evaluate effects of MM on growth of non-pathogenic iron-dependent bacterial strains (Listeria innocua, Eschericia coli, Pseudomonas fluorescens). MM (1.5 % w/v) did not significantly inhibit growth of Listeria and E. coli. However, growth of Pseudomonas fluorescens was consistently and significantly reduced by ~1 log colony forming units per ml (CFU/ml) with all levels of MM (0.5, 0.75, 1.5 % …


The Effects Of Dolphin Education Programs On Visitors' Conservation-Related Knowledge, Attitude And Behavior, Lance Joseph Miller May 2009

The Effects Of Dolphin Education Programs On Visitors' Conservation-Related Knowledge, Attitude And Behavior, Lance Joseph Miller

Dissertations

Zoological institutions typically exhibit dolphins in educational programs such as dolphin shows and interaction programs. The goal of these programs is to entertain visitors while increasing their conservation-related knowledge, attitude and behavior towards dolphins and the marine environment. The purpose of the current study was to examine dolphin shows and interaction programs in terms of their effectiveness in meeting these goals. A multi-institutional study was conducted at six different facilities throughout the United States. A repeated measures design was used to examine the knowledge, attitude and behavior of visitors before, immediately after and three months following participation in dolphin shows …

Same-Sex Social Behavior In Meadow Voles: Multiple And Rapid Formation Of Attachments, Annaliese K. Beery, David M. Routman, Irving Zucker Apr 2009

Same-Sex Social Behavior In Meadow Voles: Multiple And Rapid Formation Of Attachments, Annaliese K. Beery, David M. Routman, Irving Zucker

Neuroscience: Faculty Publications

Adult meadow voles (Microtus pennsylvanicus) are solitary in the spring–summer reproductive season, but during winter months, females and males are socially tolerant and aggregate in groups. This behavioral difference is triggered by day length: female meadow voles housed in short, winterlike day lengths form same-sex partner preferences, whereas those housed in long, summer-like day lengths are less social. The present study demonstrates that same-sex social attachments in short day lengths are not exclusive; females formed concurrent attachments with more than one individual, and with non-kin as well as siblings. Partner preferences between females were established within one day of cohousing …

Microsaccade Rate Varies With Subjective Visibility During Motion-Induced Blindness, Po-Jang Hsieh, Peter U. Tse Apr 2009

Microsaccade Rate Varies With Subjective Visibility During Motion-Induced Blindness, Po-Jang Hsieh, Peter U. Tse

Dartmouth Scholarship

Motion-induced blindness (MIB) occurs when a dot embedded in a motion field subjectively vanishes. Here we report the first psychophysical data concerning effects of microsaccade/eyeblink rate upon perceptual switches during MIB. We find that the rate of microsaccades/eyeblink rises before and after perceptual transitions from not seeing to seeing the dot, and decreases before perceptual transitions from seeing it to not seeing it. In addition, event-related fMRI data reveal that, when a dot subjectively reappears during MIB, the blood oxygen-level dependent (BOLD) signal increases in V1v and V2v and decreases in contralateral hMT+. These BOLD signal changes observed upon perceptual …

Wild Justice - Honor And Fairness Among Beasts At Play, Marc Bekoff, Jessica Pierce Apr 2009

Wild Justice - Honor And Fairness Among Beasts At Play, Marc Bekoff, Jessica Pierce

Social Cognition Collection

This essay challenges science’s traditional taboo against anthropomorphizing animals or considering their behavior as indicative of feelings similar to human emotions. In their new book Wild Justice: The Moral Lives of Animals, the authors argue that anthropomorphism is alive and well, as it should be. Here they describe some activities of animals, particularly animals at play, as clear signs that they have recognizable emotions and moral intelligence. Based on years of behavioral and cognitive research, the authors discuss in their book that animals exhibit a broad repertoire of moral behaviors, including empathy and cooperation, but here they concentrate on the …


Assessing Lameness In Cows Kept In Tie-Stalls, K. A. Leach, S. Dippel, J. Huber, S. March, C. Winckler, H. R. Whay Apr 2009

Assessing Lameness In Cows Kept In Tie-Stalls, K. A. Leach, S. Dippel, J. Huber, S. March, C. Winckler, H. R. Whay

Housing and Confinement of Farm Animals Collection

Identifying lame cows and quantifying the prevalence of lameness are important elements of cattle welfare assessment that are generally achieved by methods involving observations of each animal walking. There is no published method for assessing lameness in cows confined in tie-stalls. The objective of this study (carried out within the European Commission’s Welfare Quality® project) was to develop a suitable method and validate it for lameness detection against a published locomotion score. A series of indicators of lameness visible in tied cows was formalized into a stall assessment protocol. This was validated against a traditional locomotion score and tested for …


Research Choice And Finance In University Bioscience, David E. Ervin, Steven T. Buccola, Hui Yang Apr 2009

Research Choice And Finance In University Bioscience, David E. Ervin, Steven T. Buccola, Hui Yang

Economics Faculty Publications and Presentations

Academic bioscience's rising importance for downstream technology and growing private sector relationships have evoked substantial policy attention. We contribute to the scrutiny by asking how university bioscientists design and finance their research, with particular attention to the mutuality of research portfolio choice and funding success. The analysis requires consideration of other major influences on academic science, including scientific norms, human capital, and institutional environment. Drawing on a national survey of university bioscientists, we find that public financial support encourages more basic investigation and private support encourages more applied investigation. Yet downstream research is only moderately more excludable than upstream. Once …

A Bio-Optical Model For Syringodium Filiforme Canopies, Margaret A. Stoughton Apr 2009

A Bio-Optical Model For Syringodium Filiforme Canopies, Margaret A. Stoughton

OES Theses and Dissertations

Seagrasses are significant ecological and biogeochemical agents in shallow water ecosystems throughout the world. In many regions, seagrass meadows occupy a sufficient fraction of the coastal zone, and generate optical signatures that can be observed from space. Bio-optical models of light absorption and scattering by submerged plant canopies for certain species such as Thalassia testudinum and Zostera marina have successfully modeled the plane irradiance distribution and photosynthesis within the submerged canopies. Syringodium filiforme differs &om T. testudinttm and Z marina, in leaf morphology and canopy architecture. The objective of this study was to develop a radiative transfer model that …


When Old-Order Amish Meet New Order Science: Genetic Maladies And The Amish Dilemma, Kelley Downey Mar 2009

When Old-Order Amish Meet New Order Science: Genetic Maladies And The Amish Dilemma, Kelley Downey

Undergraduate Research Conference

The Old World Amish, an Anabaptist Christian domination in the United States and Canada are know for their plain dress, avoidance of modern technology, and separation from the mainstream society.

A traditional agricultural religious group, the Old World Amish maintains isolation from the rest of the community. Financially well-off, they are homogeneous on education, occupation by gender, age at marriage, religion/ethnicity, and health care.

Although the Amish strongly discourage marriage between close cousins, the Lancaster Amish genealogy is described as mutational - inbreeding from multiple, remote connections rather than close consanguinity (first-cousin marriages).

Amish settlements have been identified with certain …


Adult-Young Ratio, A Major Factor Regulating Social Behaviour Of Young: A Horse Study, Alice De Boyer Des Roches, Martine Hausberger Mar 2009

Adult-Young Ratio, A Major Factor Regulating Social Behaviour Of Young: A Horse Study, Alice De Boyer Des Roches, Martine Hausberger

Social Behavior Collection

Background: Adults play an important role in regulating the social behaviour of young individuals. However, a few pioneer studies suggest that, more than the mere presence of adults, their proportions in social groups affect the social development of young. Here, we hypothesized that aggression rates and social cohesion were correlated to adult-young ratios. Our biological model was naturally-formed groups of Przewalski horses, Equus f. przewalskii, varying in composition.

Methodology/Principal Findings: We investigated the social interactions and spatial relationships of 12 one- and two-yearold Przewalski horses belonging to five families with adult-young ratios (AYR) ranging from 0.67 to 1.33. We found …


To See Or Not To See: Prestimulus Α Phase Predicts Visual Awareness, Kyle E. Mathewson, Gabriele Gratton, Monica Fabiani, Diane M. Beck, Tony Ro Mar 2009

To See Or Not To See: Prestimulus Α Phase Predicts Visual Awareness, Kyle E. Mathewson, Gabriele Gratton, Monica Fabiani, Diane M. Beck, Tony Ro

Publications and Research

We often fail to see something that at other times is readily detectable. Because the visual stimulus itself is unchanged, this variability in conscious awareness is likely related to changes in the brain. Here we show that the phase of EEG α rhythm measured over posterior brain regions can reliably predict both subsequent visual detection and stimulus-elicited cortical activation levels in a metacontrast masking paradigm. When a visual target presentation coincides with the trough of an α wave, cortical activation is suppressed as early as 100 ms after stimulus onset, and observers are less likely to detect the target. Thus, …

Effect Of Noxious Stimulation Upon Antipredator Responses And Dominance Status In Rainbow Trout, Paul J. Ashley, Sian Ringrose, Katie L. Edwards, Emma Wallington, Catherine R. Mccrohan, Lynne U. Sneddon Feb 2009

Effect Of Noxious Stimulation Upon Antipredator Responses And Dominance Status In Rainbow Trout, Paul J. Ashley, Sian Ringrose, Katie L. Edwards, Emma Wallington, Catherine R. Mccrohan, Lynne U. Sneddon

Aquaculture Collection

A potentially painful experience may modify normal behavioural responses. To gauge the importance of pain relative to predation or social status, we presented competing stimuli, a predator cue or an unfamiliar social group, to two groups of noxiously treated rainbow trout, Oncorhynchus mykiss. In the predator cue experiment, fish were classified as bold or shy. Noxiously stimulated fish did not show antipredator responses, suggesting that pain is the imperative. In the social status experiment, noxiously stimulated fish held individually and undisturbed showed an increase in respiration rate and plasma cortisol. As a comparison, we used the dominant or subordinate fish …
