Determining The Critical Window Of Influence Of Pcb Perinatally On Behavioral And Hormonal Development In Sprague-Dawley Rat Pups, Natalie Sommerville, Lee A. Meserve, Howard C. Cromwell

Honors Projects

Polychlorinated biphenyls (PCB) had widespread use in the United States in commercial manufacturing in the United States until the late 1970s. Even though they were banned, measurable amounts can still be found in the environment and food sources. PCB has known effects on altering hormone development and behavior in the species Rattus norvegicus. To determine the most crucial developmental time of exposure to PCB in Sprague-Dawley rat pups, rat pups were exposed to PCB at differing weeks of either gestation period or the first postnatal week. Behavioral tests were performed for the different rat pups, as well as blood …

An Optimal Harvesting Strategy Of A Three Species Syn-Ecosystem With Commensalism And Stochasticity, M. N. Srinivas, A. Sabarmathi, K. S. Reddy, M. A. S. Srinivas

Applications and Applied Mathematics: An International Journal (AAM)

In this paper we have studied the stability of three typical species syn-ecosystem. The system comprises of one commensal S₁ and two hosts S₂ and S₃ . Both S₂ and S₂ benefit S₁ without getting themselves affected either positively or adversely. Further S₂ is a commensal of S₃ and S₃ is a host of both S₁ and S₂. Limited resources have been considered for all the three species in this case. The model equations of the system constitute a set of three first order non-linear ordinary differential equations. …

Liminal, Nina Kawar

All Theses

Throughout life everyone experiences both physical and psychological pains and adversities. In time, the body, mind and spirit are capable of healing. It is within this liminal space between infliction and renewal that the self endures an elusive process that is part of the human condition. Within my installation I have constructed a metaphor for the physical and psychological stages of healing through form, materials, color and process. The spatial environment evokes the literal and metaphorical notion of restoration through a visual, olfactory and physical experience. As the viewer navigates the space, it is the fragmentation and suggestion of form …

Collapse Of An Ecological Network In Ancient Egypt, Justin Yeakel, Mathias Pires, Lars Rudolf, Nathaniel Dominy

Dartmouth Scholarship

The dynamics of ecosystem collapse are fundamental to determining how and why biological communities change through time, as well as the potential effects of extinctions on ecosystems. Here, we integrate depictions of mammals from Egyptian antiquity with direct lines of paleontological and archeological evidence to infer local extinctions and community dynamics over a 6,000-y span. The unprecedented temporal resolution of this dataset enables examination of how the tandem effects of human population growth and climate change can disrupt mammalian communities. We show that the extinctions of mammals in Egypt were nonrandom and that destabilizing changes in community composition coincided with …

Effects Of Extreme Climate Events On Tea (Camellia Sinensis) Functional Quality Validate Indigenous Farmer Knowledge And Sensory Preferences In Tropical China, Selena Ahmed, John Richard Stepp, Colin M. Orians, Timothy S. Griffin, Corene Matyas, Albert Robbat, Sean Cash, Dayuan Xue, Chunlin Long, Uchenna Unachukwu, Sarabeth Buckley, Edward J. Kennelly

Publications and Research

Climate change is impacting agro-ecosystems, crops, and farmer livelihoods in communities worldwide. While it is well understood that more frequent and intense climate events in many areas are resulting in a decline in crop yields, the impact on crop quality is less acknowledged, yet it is critical for food systems that benefit both farmers and consumers through high-quality products. This study examines tea (Camellia sinensis; Theaceae), the world’s most widely consumed beverage after water, as a study system to measure effects of seasonal precipitation variability on crop functional quality and associated farmer knowledge, preferences, and livelihoods. Sampling was conducted in …

Role Of Group Ii Metabotropic Glutamate Receptor Subtype 2 (Mglur2) In Appetitive And Consummatory Aspects Of Ethanol Reinforcement, Kyle Allyson Windisch

Open Access Dissertations

Background: Group II metabotropic glutamate receptors (mGluR2/3) are predominately presynaptically located G_i/o coupled receptors that are highly expressed in the cortex, nucleus accumbens, amygdala, and hippocampus. Previous studies suggest that group II mGluRs are involved in regulating ethanol (EtOH) consumption and seeking following extinction (Backstrom and Hyytia, 2005; Kufahl, et al., 2011). The sipper tube model, which allows for procedural separation of seeking and consumption, was used to further clarify the role of mGluR2/3 in EtOH-seeking and consumption. The non-selective group II mGluR agonist LY379268 (LY37) and selective mGluR2 positive allosteric modulator (PAM) BINA were used to determine the …

Associated Behavioral, Genetic, And Gene Expression Variation With Alternative Life History Tactics In Salmonid Fishes, Ashley Chin-Baarstad

Open Access Dissertations

Individual differences in behavior can have potential fitness consequences and often reflect underlying genetic variation. My research focuses on three objectives related to individual level variation: 1) evaluating the innate behavioral variation within and between individuals, families, and progeny of different life-history types across time; 2) testing for differences in gene expression within the brain associated with this behavioral variation; and 3) using genetic polymorphisms to test for associations with ecotype, as well as population structure, in polymorphic populations. First, we evaluated the variation in a suite of ecologically relevant behaviors across time in juvenile progeny produced from crosses within …

Multidimensional Approach To Comparative Avian Visual Systems, Bret Alan Moore

Open Access Dissertations

Since the birth of visual ecology, comparative studies on how birds see their world have been limited to a small number of species and tended to focus on a single visual trait. This approach has constrained our ability to understand the diversity and evolution of the avian visual system. The goal of this dissertation was to characterize multiple visual dimensions on bird groups that are highly speciouse (e.g., Passeriformes), and test some hypotheses and predictions, using modern comparative tools, on the relationship between different visual traits and their association with visual information sampling behaviors. First, I developed a novel method …

The Ecology Of Infancy And Early Childhood In Rural Senegal; A Five Year Old Can Boot But Not Foot, An Exploration Of Where Biology Meets Culture, Heather Mills

Independent Study Project (ISP) Collection

This research project explores the life stages of infancy and early childhood in the village of Ndiane in the Thies region of Senegal. I will discuss how biology meets culture to influence children, parenting styles, and expectations of the life stage. How does ecology, the interaction of physical, biological and cultural landscapes, characterize childhood and the intertwined belief systems that influence parenting? The information was gathered using a combination of participant observation and free list interviews.

Park Rangers' Behaviors And Their Effects On Tourists And Tibetan Macaques (Macaca Thibetana) At Mt. Huangshan, China, Rie Usui, Lori K. Sheeran, Jin-Hua Li, Lixing Sun, Xi Wang, Alexander J. Pritchard, Alexander S. Duvall-Lash, R. Steven Wagner

Biology Faculty Scholarship

Previous studies have reported the negative impacts of tourism on nonhuman primates (NHPs) and tourists and advocated the improvement of tourism management, yet what constitutes good quality management remains unclear. We explored whether rates of macaque aggression and self-directed behaviors (SDBs) differed under the supervision of two park ranger teams at the Valley of the Wild Monkeys (VWM) in Mt. Huangshan, Anhui Province, China. The two ranger teams provisioned and managed a group of macaques on an alternating monthly basis. Monkey, tourist and ranger behaviors were collected from August 16–September 30, 2012. Macaque aggression and SDB rates did not differ …

Hla Class Ii Alleles In The Otomi Population Of The Mezquital Valley. A Genetic Approach To The History Of Interethnic Migrations In The Mexican Central Plateau, Ana Itzel Juárez-Martín, Blanca Zoila González-Sobrino, Ángel Eduardo Camarena Olvera, Ramcés Falfán-Valencia

Human Biology Open Access Pre-Prints

From a historic and genetic point of view, the Otomi of the Mezquital Valley are a frontier people that have played an important role in the making of the population dynamics of the Mexican Central Plateau. Due to their antiquity in the area, the Otomi may be bearers of ancient genetic variability, shared mainly today with other groups belonging to the Otomanguean linguistic family and with the Nahua.

This study analyzes the HLA class II allele frequencies reported in Mexican indigenous populations, in order to provide an intra-regional level historical perspective of the genetic relationships between the Otomi of the …

The Ontogeny Of Whistle Production In Infant Atlantic Bottlenose Dolphins (Tursiops Truncatus) During The First Thirty Days Of Life, Brittany Leigh Jones

Master's Theses

The manner in which dolphin calves acquire their whistle repertoire is largely unknown. This paper focuses on whistle development in four bottlenose dolphin calves during the first thirty days of life in order to increase our understanding of the early emergence of whistles and whistle-like vocalizations. The acoustic parameters of whistle-type vocalizations (i.e., whistles and whistlesquawks) that coincided with a bubblestream emission from the focal calf and/or its mother were analyzed, as were the behavioral states of the mother-calf pair during the emission of such vocals. Mother and calf whistle rates are inversely related, with the mother whistling more often …

The Effects Of Radar On Avian Behavior: Implications For Wildlife Management At Airports, Eleanor R. Sheridan

Open Access Theses

Airports are areas with a high availability of resources for wildlife to forage, breed, and roost. Airports also have different types of radars to assist with air traffic control as well as tracking of wildlife that could become a risk for aircraft. The effect of radar electromagnetic radiation on wildlife behavior is not well understood. The goal of this study was to determine if bird behavior is affected by radar in two contexts: static radar (e.g., surveillance radar) and approaching radar (e.g., aircraft weather radar). We used brown-headed cowbirds as a model species. In the static radar context, we performed …

Habitat Effects On Chick-A-Dee Call Complexity, Jacqueline Renee Lynch

Open Access Theses

Past studies on the communication systems of species in urban environments (such as Common Starlings (Sturnus vulgaris), nightingales (Luscinia megarhynchos Brehm), brown-headed cowbirds ( Molothrus ater), Southern brown tree frogs (Litoria ewingii )) have shown multiple ways that species change vocal signaling behavior to adjust to urban habitats (e.g. alarm calls and singing). This study further investigates the changes in signaling in relation to the chick-a-dee call of the Carolina chickadee (Poecile carolinensis). A secondary goal of this study was to compare both the amount of information and rate of calling across …

Across-Year Social Stability Shapes Network Structure In Wintering Migrant Sparrows, Daizaburo Shizuka, Alexis S. Chaine, Jennifer Anderson, Oscar Johnson, Inger Marie Laursen, Bruce E. Lyon

School of Biological Sciences: Faculty Publications

Migratory birds often form flocks on their wintering grounds, but important details of social structure such as the patterns of association between individuals are virtually unknown. We analysed networks of co-membership in short-term flocks for wintering golden-crowned sparrows (Zonotrichia atricapilla) across three years and discovered social complexity unsuspected for migratory songbirds. The population was consistently clustered into distinct social communities within a relatively small area (~ 7 ha). Birds returned to the same community across years, with mortality and recruitment leading to some degree of turnover in membership. These spatiotemporal patterns were explained by the combination of space …

Early Developmental Impacts On Male Traits And Female Preference In Zebra Finches (Taeniopygia Guttata), Martyna Boruta

USF Tampa Graduate Theses and Dissertations

Some male sexually selected traits are sensitive to stressors early in life and provide females with information to discriminate among males with different developmental experiences. Moreover, female early life experiences could also impact which males they choose. Females might either choose honest traits indicative of male quality, no matter their own experiences, or they might choose mates to match or compensate for their own experiences. To determine how developmental stressors alter male sexually-selected traits and female preference thereof, I exposed zebra finches (Taeniopygia guttata, ZEFI) to i) lipopolysaccharide (LPS), an immunogenic, Gram-negative bacterial component, ii) corticosterone (CORT), an avian stress …

Dreams And Learning, Cody Mebane Gibbons

Symposium

Project Summary: This study is being done to test one aspect of how paying attention to one’s dreams may influence our waking lives. The idea was inspired by research linking the brain processes involved in long-term memory storage to qualities of dreaming, as well as the potential for learning in lucid dreams. It is hypothesized that the more conscious one is of one’s dreams and dream world, the better one will be at learning. In order to test this, the dreaming ability of 300 Cal Poly students will be analyzed via dream questionnaires with the purpose of seeing if any …

Associations Between Hypothalamic-Pituitary-Adrenal Axis System Gene Variants And Cortisol Reactivity In Preschoolers: Main Effects And Gene-Environment Interactions, Haroon I. Sheikh

Electronic Thesis and Dissertation Repository

Exposure to stressful events during early development has consistently been shown to produce long lasting effects on the hypothalamic-pituitary-adrenal (HPA) axis, which may increase vulnerability to mood and anxiety disorders. Recently reported genetic association studies indicate that these disorders may be influenced, in part, by gene-environment interactions (GxE) involving polymorphisms within the corticotrophin-releasing hormone and monoaminergic system genes. However, little is known about how genetic variants and life stress work to shape children’s neuroendocrine reactivity and emerging symptoms. Therefore, the aim of this thesis is to examine main effects of candidate genes and GxE on the neuroendocrine stress response and …

Craniometric Ancestry Proportions Among Groups Considered Hispanic: Genetic Biological Variation, Sex-Biased Asymmetry, And Forensic Applications, Meredith L. Tise

USF Tampa Graduate Theses and Dissertations

Today, groups considered Hispanic in the United States consist of populations whose complex genetic structures reflect intermixed diverse groups of people who came in contact during Spanish colonization in Latin America. After coming in contact and wiping out most of the Native Americans who occupied North and Latin America, the Spanish also introduced West African individuals for labor to begin developing crops to be shipped back to Europe, resulting in the Trans-Atlantic African slave trade. These migration events and differential gene flow among males and females that occurred throughout Latin America have led to populations that have been genetically transformed …

Cardiovascular Health Among Us And Argentine University Students: A Comparative Study Of Behaviors And Risk Factors, Gina Fitzgerald, Gabriella Smith

Seaver College Research And Scholarly Achievement Symposium

Cardiovascular disease for some time has been the leading cause of death in the Western world. Primary prevention is the only way to halt the onset of cardiovascular disease, yet there is little information on the prevalence of risk factors for cardiovascular disease in young adults. This study seeks to evaluate students from the Catholic University of Argentina and Pepperdine University of America for the prevalence of CVD risk factors, as well as knowledge of CVD and daily habits that contribute to heart health. Thus we compared two cultures with very different lifestyles and prevalence of risk factors. We hypothesized …

Levels Of Altruism, Martin Zwick, Jeffrey Alan Fletcher

Systems Science Faculty Publications and Presentations

The phenomenon of altruism extends from the biological realm to the human socio-cultural realm. This paper sketches a coherent outline of multiple types of altruism of progressively increasing scope that span these two realms and are grounded in an ever-expanding sense of"self." Discussion of this framework notes difficulties associated with altruisms at different levels. It links scientific ideas about the evolution of cooperation and about hierarchical order to perennial philosophical and religious concerns. It offers a conceptual background for inquiry into societal challenges that call for altruistic behavior, especially the challenge of environmental and social sustainability.

Fishery Co-Management Opportunities Between Tribal And State Agencies: Conflict To Collaboration, J. Marty Holtgren

Dissertations, Master's Theses and Master's Reports - Open

Over the past 40 years global recognition has occurred for indigenous groups to be represented and have input in how natural resources are managed. This has largely occurred because of how management decisions have consequences to indigenous groups that reach beyond natural resource issues but into cultural, spiritual, social and political elements including sovereignty, legitimacy, justice, equity and empowerment and using indigenous paradigms to meet indigenous needs. In the United States numerous legal agreements have been reached that pair state and tribal agencies into co-management. This project concerns a recent co-management agreement between the State of Michigan and five Native …

Assessing Perceived And Documented Crop Damage In A Tanzanian Village Impacted By Human-Elephant Conflict (Hec), Rebekah R. Hoffmeier-Karimi, Bruce A. Schulte

Biology Faculty Publications

In sub-Saharan Africa human-wildlife conflict (HWC) is a growing conservation issue and human-elephant conflict (HEC) is of special concern. Crop loss to wildlife comprises a main component of HWC. Deterrent methods for crop loss are numerous and such schemes could be more effective by an improved understanding of how farmers’ perceptions align with actual causes of crop loss. Our objective was to compare the perception by farmers of the causes and extent of crop damage to the measured crop damage in fields of maize (Zea mays) using different deterrent methods. We interviewed agriculturalists in the farming village of Miti Mirefu …
