Snake Translocation Policies And Practices Within The United States, Robin E. Bedard, Megan Rottenborn, Emily Taylor

Human–Wildlife Interactions

Human–wildlife conflict with nuisance snakes (Serpentes) is rapidly increasing with human population growth and development rates. Translocation of nuisance snakes has become a widespread practice, aided by social media pages connecting people to volunteer and for-profit snake translocators. However, translocators often struggle to find information and resources from wildlife agencies about the policies required, and some may unintentionally use translocation procedures that disregard the health and survival of the snakes. The goals of this study were to (1) obtain data on policies, permitting, and training required for translocating nuisance snakes in each U.S. state that has snakes and (2) compare …

Reducing Food Scarcity: The Benefits Of Urban Farming, S.A. Claudell, Emilio Mejia

Journal of Nonprofit Innovation

Urban farming can enhance the lives of communities and help reduce food scarcity. This paper presents a conceptual prototype of an efficient urban farming community that can be scaled for a single apartment building or an entire community across all global geoeconomics regions, including densely populated cities and rural, developing towns and communities. When deployed in coordination with smart crop choices, local farm support, and efficient transportation then the result isn’t just sustainability, but also increasing fresh produce accessibility, optimizing nutritional value, eliminating the use of ‘forever chemicals’, reducing transportation costs, and fostering global environmental benefits.

Feminist Biology: Towards Gender Equity In The Biology Curriculum, Nicole Danos, Carla Y. Bonilla, Sofia Leung

Feminist Pedagogy

The current curriculum in STEM is a product of historically unequal representation of genders in the science community. As a result, most attention has been given to male biology, creating a knowledge gap that has affected our social and political perspectives, such as an underinvestment in women’s health research. Feminist biology seeks to provide equal time and weight to the impact of sex as a biological factor, using inclusive definitions of biological sex that go beyond the male/female binary. Feminist pedagogy is a method of teaching that involves engaged learning and reflection in order to create a community of learners …

Effects Of Seasonal Environment On Abundance, Behavior, Visual Signaling, And Perception In Prairie Butterflies, Grace Elizabeth Hirzel

Graduate Theses and Dissertations

Phenotypic plasticity is a widespread mechanism that allows animals to respond quickly to seasonal changes in their environment. However, the depth and complexity of these plastic responses is still being discovered. One aspect of seasonal physiology that is relatively unstudied is changes to sensory physiology and how it may explain changes in behavior. To determine how changes in seasonal conditions affect behavior, coloration, and vision, I examined populations of wild butterflies in Northwest Arkansas. Focusing on a single species, the common buckeye Junonia coenia, I found that seasonal coloration covaries with thermoregulating behavior and is accompanied by changes in visual …

Seagrass Epibiont Biodiversity In The Northern Gulf Of Mexico, Kathryn Wyssmann

LSU New Orleans Theses and Dissertations

Epibionts on seagrass leaves contribute substantially to productivity and trophic interactions in seagrass ecosystems. Differences in epibiont assemblages and factors that contribute to epibiont diversity have been little studied on the seagrass Halodule wrightii in the northern Gulf of Mexico (nGoM). We used a metabarcoding approach to describe epibiont assemblages on H. wrightii leaves in four bays across the nGoM and to test whether epibiont assemblages differed spatially at local levels (within bays) or regional levels (from west to east). Furthermore, we tested if epibiont diversity was related to environmental conditions and/or seagrass productivity. Epibiont assemblages differed significantly between bays …

Exploring The Interrelationships Among Structural Complexity, Multi-Trophic Biodiversity, And Ecosystem Productivity In Forested Ecosystems., Ayanna St. Rose

Graduate Theses and Dissertations

Forests play a pivotal role in sustaining global biodiversity and mitigating the global climate, as they serve as the primary refuge for terrestrial biodiversity and effectively capture and store atmospheric carbon dioxide. However, changing climate and land use are altering the geographic distribution, physical structure, and productivity of forested ecosystems that can have profound impacts on biodiversity conservation, forest productivity, and global climate. This dissertation contributes to our understanding of multifaceted interactions between the physical and biological structural complexity and ecosystem functions in forested landscapes across the United states by using openly available data from two national networks: the National …

Human-Bat Interactions In A Disease Emergence Hotspot: Implications For Human Health And Bat Conservation, Reilly Tempest Jackson

Graduate Theses and Dissertations

Bats are an ecologically important taxon that can host zoonotic pathogens. Globally, many bat species are synanthropic and live closely with humans, often roosting in man-made structures. The spatial overlap between humans and bats creates opportunities for human-bat contact, which can lead to human exposure to bat-borne pathogens and conflicts that cause bat mortality. Despite this risk, little is known about the drivers and characteristics of these human-bat interactions in buildings and work is needed to understand this aspect of the wildlife-urban interface. In Chapter I, I present a literature review that identifies the geographic and taxonomic trends in reported …

Controlled Radiation Capsule For Precision And Rapid Cancer Treatment, Hoseon Lee, Zsolt Kollar, Bailey R. White, Junia Nguyen, David Roque, Sowjanya Palagani

Symposium of Student Scholars

This research aims to transform cancer treatment through the optimization of brachytherapy, with a focus on reducing treatment duration, setup complexities, and financial burdens, all while emphasizing patient safety. Patients living at a distance from radiation clinics, particularly those undergoing extended Low Dose Radiation brachytherapy, often struggle with the formidable financial challenges associated with securing nearby accommodations. In response to these issues, the research introduces a radiation capsule designed to condense the conventional six-month treatment period to approximately just one week, thereby significantly reducing the duration of required accommodations. This capsule is especially relevant considering the construction cost of $40 …

Quantifying The Role Of Water Quality On Nitrogen Cycling In A Trophic Estuary, Kayla Gonzalez-Boy

Symposium of Student Scholars

Jobos Bay Estuary is an intertidal, tropical estuary located in southern Puerto Rico. The estuary covers about 12 km² and has a variety of habitats, such as seagrass beds, mangroves, mud flats, and coral reefs, which play important roles in sediment trapping and water quality maintenance. Seagrasses also serve as nursery and feeding grounds and provide shelter for macrofauna. Currently, the role of seagrasses and water quality on nitrogen (N) cycling in trophic estuaries is not well constrained. Understanding variations in sediment-based effects on N cycling rates and transformations, and how they are associated with water quality, is an …

Book Review: Kings, Conquerors, Psychopaths: From Alexander To Hitler To The Corporation, Tim Bakken

Genocide Studies and Prevention: An International Journal

The book Kings, Conquerors, Psychopaths is a survey of a vast amount of human wrongdoing. It lays bare the motivations of aggressors who wish to subjugate nations or groups of people and corporate executives and government bureaucrats who make discretionary decisions that harm people. Along with cataloging mass killings by despots and soldiers, the book includes stories about Ponzi-schemers and the deaths of automobile drivers and passengers who were killed by vehicle defects known to the manufacturer. The book posits that “[p]owerful, elite forces are trying to force us backward toward a non-democratic state, one where power, wealth, and prerogative …

Biofilm Formation In Bath Toys, Kelsey Daniels

Harrisburg University Research Symposium: Highlighting Research, Innovation, & Creativity

Biofilms are a collective of microorganisms and matrixes that can grow on a variety of surfaces. Depending on the environment, the growth of biofilm formation can vary. These environmental factors may include temperature or access to nutrients. Overtime unkept bath toys can form a biofilm layer, which can be hard to remove and hazardous to children. It is important to understand biofilms so that a variety of methods can be successfully used against them.

Field-Based Selenium Partitioning Coefficients, Trophic Transfer Factors, And Otolith Time-Series Analyses For A Walleye Community From An Ecotonal Plains Reservoir, Colorado. Iii., Scott J. Herrmann, Del Wayne R. Nimmo, Lynn M. Herrmann-Hoesing, Igor V. Melnykov, Norman M. Halden

Western North American Naturalist

Little is known about partitioning coefficients, tissue bioaccumulation, trophic transfer, and otolith timeseries analyses of selenium (Se) in a fishery dominated by walleye (Sander vitreus) that consume multiple prey species and occur in a Se-rich reservoir. Concentrations of dissolved total Se in Pueblo Reservoir water consistently exceeded the current EPA criterion benchmark for lentic aquatic ecosystems. The major objectives of this study were to analyze Se in diet-borne consumables of a walleye fishery and perform time-series trend tests of 21 walleye sagittae. In contrast to previous reports, we proposed investigating Se partitioning from water to subsequent trophic levels …

Potentially Adaptive Significance Of Genome Size Diversity Across Ecological Gradients And Seed Size In Ivesia (Rosaceae), Israel T. Borokini, Shaun R. Broderick, Zhi Gao, Joshua M. Hallas, James A. Birchler, Mary M. Peacock

Western North American Naturalist

Variation in genome size across taxa has been explained using neutral and nonadaptive theories; however, genome size variation among taxonomic groups can also be shaped by natural selection if it correlates with functional traits. This study investigated the potential adaptive significance of genome size in Ivesia, a radiating genus distributed in the western North American desert ecosystems. We estimated the genome size of 34 taxa (including 31 Ivesia taxa, 2 Potentilla taxa, and 1 Horkelia taxon) using flow cytometric methods. For each taxon, leaf samples were collected from 6 individuals in 1 location each; intraspecific genome size variation was …

Effects Of Fire On Kangaroo Rats In The San Joaquin Desert Of California, David J. Germano, Lawrence R. Saslaw, Brian L. Cypher, Linda Spiegel

Western North American Naturalist

Fire can alter ecological communities, particularly those that are not fire-adapted, such as desert communities. We examined the effects of fire on rodent communities in the San Joaquin Desert of central California. Of particular interest were the effects on kangaroo rats (Dipodomys spp.) including 2 rare species, the giant kangaroo rat (D. ingens) and the short-nosed kangaroo rat (D. nitratoides brevinasus). Lightning caused multiple fires in arid scrub habitat in western Kern County in 1993. We trapped rodents at 7 sites along paired transects, with one transect in a burned area and one in a …

The world recognition of Seafood nutritional value for human consumption remain consistent throughout the time. Different informations and aspects have been studied and considered and generated various data sets but limited informations found about the biochemical concentration of various fishery species caught in the Pakistan. Therefore, the recent study design to evaluate the proximate levels of components in the edible component (flesh) of commercial shrimp species were studied. Four shrimp species; Fenneropenaeus indicus, Metapenaeopsis stridulans, Metapenaeus stebbingi, and Parapenaeopsis stylifera were selected for the assessment of proximate composition. The selected shrimp species were collected from the fishery catch of Korangi …

Using Μct Scans To Create 3d Skull Puzzles As Open-Access Pedagogical Tools For Anatomy And Comparative Osteology Classes., Alexis Slack

Honors Thesis

As access to affordable 3D printing technologies increases, the use of Computed Tomography (CT) technologies is well positioned to contribute to the advancement of pedagogical experiences through the creation of physical models for teaching. Such complementary efforts may enhance broader impacts by simultaneously boosting the education system with a unique hands-on experience for students and providing an alternative to expensive osteological and other artificial models. Two 3D printed skull puzzles were created to aid in teaching human and vertebrate anatomy, and comparative osteology courses. After segmenting all the bones from each respective skull, the individual skeletal elements were 3D printed, …

Hedgehog Signaling As An Underlying Mechanism For Midline Modification During Asexual Reproduction In Convolutriloba Longifissura Acoels, James M. Sikes Ph.D., Jaclyn Cherry

Master's Theses

The mechanisms that control midline specification and modification during post-embryonic development are some of the least understood in developmental biology.  Because acoel flatworms have varied modes of asexual reproduction which can involve the dramatic modification of their orthogonal axes and midline, we have chosen the acoel species Convolutriloba longifissura as a model to study the mechanisms behind midline modification.  C. longifissura asexually reproduces through a double fission process where novel midlines arise within laterally located tissues while the adult midline is destroyed prior to an initial transverse fission event, which is then followed by a second longitudinal fission.  Previous work …
