Humpback Whale Movements And Behavior In Response To Whale-Watching Vessels In Juneau, Ak, Alicia Schuler, Sarah Piwetz, Jacopo Di Clemente, David Steckler, Franz Mueter, Heidi C. Pearson

Faculty, Staff, and Students

The whale-watching industry in Juneau, Alaska relies primarily on the presence of North Pacific humpback whales (Megaptera novaeangliae). To meet demands from the rapidly growing tourism industry, the number of whale-watching vessels in this region has tripled over the last 18 years. As a result, increased vessel presence could have negative effects on humpback whales, ranging from short-term behavioral disturbance to long-term impacts. The current humpback whale viewing regulations are outdated and may not be as effective as they were 18 years ago, when both the whale-watching industry and humpback whale population were smaller. The present study assessed how humpback …

Rapid Fabrication Of Custom Microfluidic Devices For Research And Educational Applications, Megan Levis, Fernando Ontiveros, Jonathan Juan, Anthony Kavanagh, Jeremiah J. Zartman

Biology Faculty/Staff Publications

Microfluidic devices allow for the manipulation of fluids, particles, cells, micro-sized organs or organisms in channels ranging from the nano to submillimeter scales. A rapid increase in the use of this technology in the biological sciences has prompted a need for methods that are accessible to a wide range of research groups. Current fabrication standards, such as PDMS bonding, require expensive and time consuming lithographic and bonding techniques. A viable alternative is the use of equipment and materials that are easily affordable, require minimal expertise and allow for the rapid iteration of designs. In this work we describe a protocol …

Territorial Landscapes: Incorporating Density-Dependence Into Wolf Habitat Selection Studies., Shawn T O'Neil, Dean E Beyer, Joseph K Bump

Michigan Tech Publications, Part 1

Habitat selection is a process that spans space, time and individual life histories. Ecological analyses of animal distributions and preferences are most accurate when they account for inherent dynamics of the habitat selection process. Strong territoriality can constrain perception of habitat availability by individual animals or groups attempting to colonize or establish new territory. Because habitat selection is a function of habitat availability, broad-scale changes in habitat availability or occupancy can drive density-dependent habitat functional responses. We investigated density-dependent habitat selection over a 19-year period of grey wolf (

Genotyping-By-Sequencing Of Gossypium Hirsutum Races And Cultivars Uncovers Novel Patterns Of Genetic Relationships And Domestication Footprints, S Zhang, Y Cai, J Guo, K Li, Et Al

School of Biological and Marine Sciences

Determining the genetic rearrangement and domestication footprints in Gossypium hirsutum cultivars and primitive race genotypes are essential for effective gene conservation efforts and the development of advanced breeding molecular markers for marker-assisted breeding. In this study, 94 accessions representing the 7 primitive races of G hirsutum, along with 9 G hirsutum and 12 Gossypium barbadense cultivated accessions were evaluated. The genotyping-by-sequencing (GBS) approach was employed and 146 558 single nucleotide polymorphisms (SNP) were generated. Distinct SNP signatures were identified through the combination of selection scans and association analyses. Phylogenetic analyses were also conducted, and we concluded that the Latifolium, Richmondi, …

Doctrinal Evolution And The Right Against Self-Incrimination, Eliot T. Tracz

The University of New Hampshire Law Review

The Fifth Amendment’s right against self-incrimination is one of the most well-known constitutional protections as it is often referenced in movies, television shows, and in the news. Despite this wide-spread awareness of the right against self-incrimination, the Federal Circuit Courts remain split over whether the right attaches before or during trial. The specific point of contention is when a “criminal case” commences.

This article examines the history of the right against self-incrimination beginning with its common-law origins in Great Britain. The evolution of the right against self-incrimination is explored up to the present-day circuit split, and the cases involved in …

Serum Amyloid A-Mediated Inflammasome Activation Of Microglial Cells In Cerebral Ischemia, Jin Yu, Hong Zhu, Saeid Taheri, William Mondy, Leonardo Bonilha, Gayenell S. Magwood Phd, Rn, Faha, Faan, Daniel Lackland, Robert J. Adams, Mark S. Kindy

Publications

Serum amyloid A (SAA) proteins are acute-phase reactant associated with high-density lipoprotein (HDL) particles and increase in the plasma 1000-fold during inflammation. Recent studies have implicated SAAs in innate immunity and various disorders; however, the precise mechanism eludes us. Previous studies have shown SAAs are elevated following stroke and cerebral ischemia, and our studies demonstrated that SAA-deficient mice reduce inflammation and infarct volumes in a mouse stroke model. Our studies demonstrate that SAA increases the cytokine interleukin-1β (IL-1β), which is mediated by Nod-like receptor protein 3 (NLRP3) inflammasome, cathepsin B, and caspase-1 and may play a role in the pathogenesis …

Risky Times And Spaces: Settler Colonialism And Multiplying Genocide Prevention Through A Virtual Indian Residential School, Andrew Woolford, Adam Muller, Struan Sinclair

Genocide Studies and Prevention: An International Journal

In this article, we examine how the logic of genocide prevention aligns with a settler colonial logic of elimination. We examine how the exclusion of cultural techniques of destruction from consideration contributes to the logic of elimination, and we suggest this is, in part, a structural problem built into the logic of genocide prevention. Along these lines, we interrogate linear and molar approaches to genocide prevention and propose, in addition to existing macro-level strategies, a molecular, everyday ethos of genocide prevention that is attuned to genocidal intimacies and seeks to foster anti-genocide habits and practices. In so doing, we argue …

Relation Between Relative Handgrip Strength, Chronological Age And Physiological Age With Lower Functional Capacity In Older Women, W. Souza Saraiva, J. Prestes, S. Schwerz Funghetto, J. W. Navalta, R. A. Tibana, Dahan Da Cunha Nascimento

Kinesiology and Nutrition Sciences Faculty Research

Purpose: Relative handgrip strength (RHGS), Aged Based on Exercise Stress Testing (A-BEST), and chronological age were evaluated as predictors of impaired mobility in older women. Methods: Participants included 88 older women (mean age 68.13±6.02 years) referred for exercise stress testing. Estimated physiological age was computed based on exercise capacity, chronotropic reserve index, heart rate recovery, and medication that could affect heart rate. RHGS was measured using a validated handgrip hydraulic dynamometer and mobility was evaluated by timed up and go test (TUG-test). A hierarchical multiple regression predicted TUG-test performance from A-BEST, chronological age and RHGS. Results: After adjustment for diabetes, …

The Role Of Storytelling In Promoting The Adoptions Of Older Children, Sarah Melody Vaughn

Senior Honors Theses

The need for older children to be adopted out of foster care in the United States is very prevalent. Adoption and foster care organizations are constantly changing and shifting their marketing techniques and promotional materials in order to advocate for the adoption of children out of foster care. One strategy that many organizations employ is a storytelling strategy. These organizations tell the stories of broken children stuck in the foster care system with no hope of finding a forever family. They also tell redemption stories; stories of families that have sacrificed everything to adopt a needy child. Although stories are …

Gravity As A Continuum: Effects Of Altered Gravity On Drosophila Melanogaster Immunity, Amber M. Paul, Joe Olivieri, Sharmila Bhattacharya

Publications

The impact of spaceflight on immune function is undoubtedly a critical focus in the area of space biology and human health research. Heat shock proteins (Hsp) are an evolutionarily conserved family of proteins that are expressed in response to cellular and physiological stressors, experienced during radiation exposure, confinement, circadian rhythm disruption, and altered gravity (hypergravity experienced at launch/landing and microgravity experienced in-flight). In particular, Hsp70 aids in the folding of proteins, facilitates the movement of proteins across the membranes during signal transductions and can stimulate innate immunity. Since Hsp70 is induced during cellular stress, and can act as a stimulator …

Modeled Microgravity Induces Neutrophil Extracellular Trap (Net)Osis Formation And Reduced Phagocytosis Of Polymorphonuclear Neutrophils, Amber M. Paul

Publications

Spaceflight can dysregulate immunity, by way of increasing granulocytes numbers with impaired function. Polymorphonuclear neutrophils (PMN) are granulocytes that are first responders to infection or injury, and consist of the largest pool of immune cells in humans. PMNs function during innate immunity, through phagocytosis and promotion of inflammation, via the release of reactive oxygen species (ROS) mediators and granule-containing enzymes, such as myeloperoxidase (MPO) and NADPH oxidase-2 (NOX-2). In addition, neutrophil extracellular trap (NET) formation is another mechanism of PMN surveillance that works independently of engulfment phagocytosis, and is a last resort function that can induce NETosis or PMN-specific cell …

Social Support, Psychological And Physical States Among Japanese Women With Breast Cancer, Reiko Makabe

Dissertations

In Western cultures, it has been reported that social support has effects on health outcomes among women with breast cancer. However, little is known about social support and the effects on health outcomes among Japanese women with breast cancer. In addition, there are no instruments with established reliability and validity to measure social support specific to Japanese populations giving consideration to cultural differences. A cross-sectional study was designed incorporating quantitative and qualitative approaches for the purposes of: (1) testing the reliability and validity of instruments developed to measure social support with Western populations when used with Japanese women with breast …

Maternal Attitudes, Feeding Practices And Child Weight-For-Length Percentiles: Maternal Participation Vs. Non-Participation In A Prenatal Infant Nutrition Education Session, Connie S. Lewis

Dissertations

Obesity has reached epidemic proportions nationally and internationally. All ages are affected resulting in physiological and psychological health consequences. Obesity-related habits that begin in childhood may continue into adulthood suggesting the need for developmentally targeted approaches. Efforts to reduce obesity should begin early in life with interventions targeting infants and young children. Is there a difference in infant feeding attitudes, the initiation of breastfeeding practice, the introduction of solid foods practice, and child weight-for-length percentiles at 12, 18, and 24 months between mothers who participated in a prenatal infant nutrition education session and mothers who did not participate? The purpose …

The "Statutory Rape" Myth: A Case Law Study Of Sexual Assaults Against Adolescent Girls, Isabel Grant, Janine Benedet

All Faculty Publications

This article examines three years of Canadian case law involving sexual offences against adolescent girls between the ages of twelve and seventeen inclusive, with a view to identifying the types of cases that are making it to court, whether these cases are resulting in convictions, and what are the types of sentences being imposed on individuals convicted of these offences. A significant majority of cases under review involved men considerably older than the complainant. The average age difference between the accused and the complainant was nineteen years and, where family members were excluded, 15.6 years. The small number of cases …

Reconstructing Geographic And Trophic Histories Of Fish Using Bulk And Compound-Specific Stable Isotopes From Eye Lenses, Amy A. Wallace

USF Tampa Graduate Theses and Dissertations

The present research examined the viability and utility of eye lenses as a source of lifetime stable-isotope records in fish. It is presented in three sections. The first section compared bulk isotopic variation (bulk analysis) within fish eye-lenses at two temporal resolutions and compared patterns obtained from left and right eyes. The first temporal resolution was lower in an attempt to expose broad-scale isotopic changes during life while reducing effort and cost. This approach did reveal lifetime patterns, but tended to miss certain life events, particularly during early life. The second resolution was higher and provided detail that was missed …

Changing Environments And Genetic Variation: Natural Variation In Inbreeding Does Not Compromise Short-Term Physiological Responses, James Buckley, Rónán Daly, Christina A. Cobbold, Karl Burgess, Barbara K. Mable

School of Biological and Marine Sciences

Selfing plant lineages are surprisingly widespread and successful in a broad range of environments, despite showing reduced genetic diversity, which is predicted to reduce their long-term evolutionary potential. However, appropriate short-term plastic responses to new environmental conditions might not require high levels of standing genetic variation. In this study, we tested whether mating system variation among populations, and associated changes in genetic variability, affected short-term responses to environmental challenges. We compared relative fitness and metabolome profiles of naturally outbreeding (genetically diverse) and inbreeding (genetically depauperate) populations of a perennial plant,Arabidopsis lyrata, under constant growth chamber conditions and an outdoor common …

Feasibility Of Multi-Year Forecast For The Colorado River Water Supply: Time Series Modeling, Brian Plucinski, Yan Sun, Shih-Yu (Simon) Wang, Robert R. Gilies, James Eklund, Chih-Chia Wang

Mathematics and Statistics Faculty Publications

The future of the Colorado River water supply (WS) affects millions of people and the US economy. A recent study suggested a cross-basin correlation between the Colorado River and its neighboring Great Salt Lake (GSL). Following that study, the feasibility of using the previously developed multi-year prediction of the GSL water level to forecast the Colorado River WS was tested. Time-series models were developed to predict the changes in WS out to 10 years. Regressive methods and the GSL water level data were used for the depiction of decadal variability of the Colorado River WS. Various time-series models suggest a …

Abstract: At present, the research of the interactive process between plants and the flame mainly focuses on the visual simulation of forest fire scenario, but it is lack of the study on description of the interaction of individual plants and flame in detail. Aiming at this issue, this paper proposed a visual solution to model the process of a single plant burning. We established a plant model based on the branch node relationship and used particle system to model the flame. We set up a distance temperature field around a flame by using bounding sphere, and used a collision …

Recognition Method On Two-Phase Flow Regime Based On Cross Recursive Analysis, Yongbo He, Yushan Dong, Rongrong Xue

Journal of System Simulation

Abstract: Aiming at the problems that the two-phase flow regime recognition speed is slow and the recognition accuracy is low, a flow regime recognition method is proposed based on cross recursive analysis (CRA) without imaging. The false nearest neighbors are used to analyze flow regime capacitance values measured by capacitance sensor to obtain an optimal embedding dimension; and the embedding dimension of cross recursive plot is established for several typical flow patterns. The capacitance values of the simulation flow regimes and the reference flow regimes are analyzed using cross recursion to get a set of cross recursive plots. The similarity …

Modeling And Simulations Of Peptoids, Pu Du

LSU Doctoral Dissertations

Polypeptoids, or poly-N-substituted glycines, are a class of sequence defined polymers that are structural mimics of polypeptides. Polypeptoids currently have received a growing interest due to their improved thermal stability, larger chemical diversity, and easier synthetic pathways as compared to peptides. Their lack of backbone hydrogen bonding and stereochemistry coupled with their easily tunability make them an ideal prototypical model system to study the effect of secondary/non-covalent interactions on self-assembly in solution. In order to develop a molecular level understanding of the effect of secondary interactions on polypeptoid self-assembly, systematic studies were carried out using molecular dynamics simulations on several …

Lake Variations On Tibetan Plateau Of Recent 40 Years And Future Changing Tendency, Zhu Liping, Zhang Guoqing, Yang Ruimin, Liu Chong, Yang Kun, Qiao Baojin, Han Boping

Bulletin of Chinese Academy of Sciences (Chinese Version)

The Tibetan Plateau lakes, with more than 50% area of the total lakes in China, are an important part of the Asia Water Tower. From 1970s to 2018, the number and area of lakes increased obviously, but the changing rate was not uniform. Before 1990, the negative balance of lake water storage was caused by low temperature inhibition of melting water. From 1990 to 2000, lake water storage increased associated with increased melting water due to the rising of temperature. After 2000, precipitation was the main factor leading to the increase of lake water storage, but the continuous temperature rising …

Effects Of Changed Asian Water Tower On Tibetan Plateau Ecosystem: A Review, Di Yangping, Zhang Yangjian, Zeng Hui, Tang Ze

Bulletin of Chinese Academy of Sciences (Chinese Version)

As the "water tower" of Asia, the Tibetan Plateau provides basic water resources for the regional ecosystems. Among the variety of water resources, natural precipitation is most relevant to ecosystems, and temperature also affects soil moisture availability by regulating evapotranspiration, thus affecting ecosystem process. From the aspects of community composition and structure, vegetation phenology, coverage and productivity, and water conservation function by ecosystems, this paper reviewed the series of impacts caused by changed water resources on the Tibetan Plateau ecosystems in recent years, and the underlying mechanism was further revealed. The shifted water conditions led to changes in community coverage, …

Determinants Of Campylobacter Infection And Association With Growth And Enteric Inflammation In Children Under 2 Years Of Age In Low-Resource Settings, Md Ahshanul Haque, James A. Platts-Mills, Estomih Mduma, Ladaporn Bodhidatta, Pascal Bessong, Sadia Shakoor, Gagandeep Kang, Margaret N. Kosek, Aldo A M Lima, Zulfiqar Ahmed Bhutta

Department of Pathology and Laboratory Medicine

Campylobacter species infections have been associated with malnutrition and intestinal inflammation among children in low-resource settings. However, it remains unclear whether that association is specific to Campylobacter jejuni/coli. The aim of this study was to assess the association between both all Campylobacter species infections and Campylobacter jejuni/coli infections on growth and enteric inflammation in children aged 1-24 months. We analyzed data from 1715 children followed from birth until 24 months of age in the MAL-ED birth cohort study, including detection of Campylobacter species by enzyme immunoassay and Campylobacter jejuni/coli by quantitative PCR in stool samples. Myeloperoxidase (MPO) concentration in stool, …

Breaking Coastal Hypoxia: Destratification Of Gulf Of Mexico Deadzone To Encourage Oxygen Transport Downwards To Maintain Marine Fauna, Veda Thipparthi

LSU Master's Theses

As a consequence of seasonal eutrophication and human input, a vast hypoxic area termed The Dead Zone develops every year in the Gulf of Mexico (GOM) during summer along the Louisiana coastline characterized by vertical seawater density-stratification with oxygen concentrations less than 2 mg.l^-1 at the seafloor. It poses a threat to bottom-dwelling faunae and their environment which has negative ecological and economic consequences. This project aims to mitigate hypoxia by employing mechanical impellers placed at strategic water depths and locations in the Gulf. Enhanced transport of oxygen results by mixing oxygen-enriched seawater at the surface, downward into the …
