Eristalis Tenax Movement Behavior In Response To Light, Temperature, And Food, Jeffery J. Zheng, Zdena M. Janderova, Jason D. Lang
Georgia Journal of Science
Drone flies, Eristalis tenax (Diptera: Syrphidae), are important generalist pollinators and visit flowers globally that range widely in color. The flies’ photoreceptors allow them to sense light wavelengths between 300-600 nm and E. tenax exhibit a positive phototactic response. To understand the effects of light on E. tenax movement, we conducted two-choice behavioral tests to determine their phototactic response to different wavelengths of light across the spectrum (ultraviolet to red light, plus full spectrum white light). The drone flies moved most and quickest toward sunlight, with almost twice the percentage of flies moving toward sunlight than toward black and …

Students’ Acquisition Of Agricultural And Entrepreneurship (Agripreneurship) Knowledge And Skills: Does Instructional Approach And Their Sex Matter?, Stephen C. Mukembo, M. Craig Edwards, J. Shane Robinson
Journal of International Agricultural and Extension Education
Agricultural and Entrepreneurship education are interdisciplinary due to amalgamating the natural sciences and social sciences. These disciplines have gained the interest of those looking to equip youth with skills for self-reliance. Teachers employ various instructional approaches, including student-centric approaches such as project-based learning (PjBL) and teacher-centric methods, for example, the lecture method, to facilitate learning. Existing research, however, suggests that students’ learning can be influenced by other factors, for example, learning styles, socio-cultural norms, sex stereotypes, and the instructional approach(es) used. We examined the impact of using the lecture method (counterfactual group) versus PjBL (treatment group) approaches on student acquisition …

After a semester of learning, both in class and in nature, my writing honed in further on this human-nature divide. To me, I see humans as part of nature – as we are mammals, animals, part of the food chain, biological beings no higher than others on our planet. We have simply constructed this false narrative around us within our societies, minds and media that embeds this division between us and nature, between us and wildlife. Humans have been managing, stewarding, living off and within landscapes for thousands of years. As time and technology evolved, a lot of people began …

Does Social Organization, Litter Size, Sexual Dimorphism, And Phylogeny Influence Multiple Paternity In Mammals?, Madison Roberts
Honors Theses
Animal social systems are complex and the dynamics of one component could influence the dynamics of another. The aim of this literature search research was to determine the interrelatedness between mammalian social organization and mating system, two components of social systems. The mating system was represented by multiple paternity, the number of litters with more than one father, as genetic analysis tells which individuals reproduced with who. Variables that might influence multiple paternity amongst extant mammalian species included in this study are variable social organization, male social organization, mean litter size, sexual dimorphism, and phylogenetics. Analysis was conducted using 56 …

Electronic Theses, Projects, and Dissertations
Serotonin has been found to regulate several cognitive and physiological functions, and its role in depression and other neuropsychiatric disorders has been a focus of research. More specifically, a wealth of research regarding serotonin focuses on serotonergic medications in the treatment of neuropsychiatric disorders, such as depression and anxiety, and stimulates the 5-HT1A and 5-HT1B receptors. Within the last decade, there has been an increase in prescriptions of psychotropic medication for children, however, the efficacy and adverse effects of these drugs have not been evaluated in younger populations. While antidepressants reduce symptoms of depression in adults, they are …

Classification Of Large Scale Fish Dataset By Deep Neural Networks, Priyanka Adapa
Electronic Theses, Projects, and Dissertations
The development of robust and efficient fish classification systems has become essential to preventing the rapid depletion of aquatic resources and building conservation strategies. A deep learning approach is proposed here for the automated classification of fish species from underwater images. The proposed methodology leverages state-of-the-art deep neural networks by applying the compact convolutional transformer (CCT) architecture, which is famous for faster training and lower computational cost. In CCT, data augmentation techniques are employed to enhance the variability of the training data, reducing overfitting and improving generalization. The preliminary outcomes of our proposed method demonstrate a promising accuracy level of …

Investigating Monodelphis Domestica As An Alternative To The Mus Musculus As An Animal Model, Cristian M. Botello, John L. Vandeberg, Mario Gil
Research Symposium
Background: Mus Musculus is one of the first and one of the most widely used animal models in current neuroscience literature (Phifer-Riley & Nachmann, 2015). However, the research community needs alternatives to rodent models to study the mammalian brain. Research is needed to see if antibodies that target tyrosine hydroxylase, which are well researched in mice, can also be used to study the Monodelphis domestica brain.
Methods: Following transcardial perfusions and brain extractions, mouse and opossum brains were processed and stained for tyrosine hydroxylase (and with Nissl). Opossum brains will then be sliced and processed using IHC methods to compare …

The Implications Of Solidarity For Food Ethics, John Sniegocki
The Journal of Social Encounters
This essay examines numerous ways in which commitments to solidarity have relevance in the area of food ethics. Among the topics explored are food insecurity and hunger, workers’ rights, ecology, and the treatment of animals. Particular attention is paid to the impacts of the production and consumption of animal products. These issues are examined through the lens of the developing understanding of solidarity present in the tradition of Catholic social teaching (CST). The ethical framework provided by CST, it is suggested, could be further enhanced by insights drawn from the growing tradition of “Black veganism” and its holistic, intersectional understanding …

The Role Of Serotonin In The Estradiol-Dependent Selectivity Of Auditory Regions In Songbirds, Calista J. Henry
Electronic Thesis and Dissertation Repository
Breeding-typical levels of estradiol in songbirds has been shown to lead to selective auditory processing and induce a release of serotonin in auditory regions of the forebrain. These findings triggered the question of whether auditory discrimination is driven by estradiol directly, or by the associated release of serotonin. I treated non-breeding female white-throated sparrows (Zonotrichia albicollis) with either blank implants, 17β-estradiol, serotonin enhancer and blank implants, or serotonin antagonist and 17β-estradiol implants. Birds then heard male conspecific songs or control tones, and ZENK-immunoreactivity was quantified in the caudomedial nidopallium (NCM) and caudomedial mesopallium (CMM). While I did not …

A Four-Pronged Approach To Addressing A Wild Pig Invasion In A Bottomland And Upland Forested Landscape, Tyler Scott Evans
Theses and Dissertations
Among exotic species that are capable of invading, establishing, and reaching pest status, few pose the range of impacts to biotic (e.g., competition with native species, predation, herbivory, introduction of other exotics) and abiotic (e.g., soil, hydrology) ecosystem components that can be attributed to the wild pig (Sus scrofa). Despite the presence of wild pigs throughout the southeastern United States for centuries, new invasions continue to occur in previously uninhabited and often under-investigated landscapes, including bottomland and upland forests. The recent invasion of the Sam D. Hamilton Noxubee National Wildlife Refuge (hereafter, NNWR) in east-central Mississippi represents an …

Shark-Diving Tourism In The Macaronesian Archipelagos: Challenges And Opportunities, Pedro Gonzáles Mantilla
ITSA 2022 Gran Canaria - 9th Biennial Conference: Corporate Entrepreneurship and Global Tourism Strategies After Covid 19
The Macaronesian region is typically heavily exploited by fisheries; however, in recent years, marine wildlife tourism has become popular and a shark-diving industry has emerged, potentially presenting an alternative for the sustainable use of sharks. Combining a literature review with interviews with dive operators conducting shark encounters in the Macaronesian archipelagos, we provide an overview of the challenges and conservation potential of shark-diving tourism for these territories. Owing to the regular presence of important shark species for tourism and the growth of the scuba-diving industry, shark-diving has potential to expand over the region. Yet, the overlap between European industrial fishing …

Liquid Border, Yingfan Jia
Masters Theses
A River is a mighty and constantly-evolving force, leaving behind an intricately designed and constantly changing system. Not just a river, the Rio Grande stretches all the way from Colorado before intersecting with the US-Mexico Border in southern Texas - a point where the powerful forces of nature now merge with a clearly-defined political boundary. The outcome of this is a unique ecological niche, which may often go unnoticed despite its distinctiveness.
Texas is famous for its farms and ranches, and the Rio Grande Valley of South Texas was once an agricultural hub. However, urbanization and the depletion of water …

Statistical And Biological Analyses Of Acoustic Signals In Estrildid Finches, Moises Rivera
Dissertations, Theses, and Capstone Projects
Acoustic communication is a process that involves auditory perception and signal processing. Discrimination and recognition further require cognitive processes and supporting mechanisms in order to successfully identify and appropriately respond to signal senders. Although acoustic communication is common across birds, classical research has largely disregarded the perceptual abilities of perinatal altricial taxa. Chapter 1 reviews the literature of perinatal acoustic stimulation in birds, highlighting the disproportionate focus on precocial birds (e.g., chickens, ducks, quails). The long-held belief that altricial birds were incapable of acoustic perception in ovo was only recently overturned, as researchers began to find behavioral and physiological evidence …

Towards Urban Biodiversity: Simulating Design Parameters For Wildlife-Inclusive Green Infrastrcuture, Alisa Abdulghany, Baher Farahat
BAU Journal - Creative Sustainable Development
As of 2021, more than half of the global population resides in urban areas. This resulted in an overwhelming footprint affecting species habitat areas leading to biodiversity loss. By definition, urban biodiversity is the diversity of living things within the urban realm. By providing chances for habitat as part of new developments, preserving on-site habitats, and attempting to connect with the local ecosystems, we can help promote biodiversity. Green infrastructure (GI), which includes all semi-natural areas in the urban context, can serve as a vessel for biodiversity. Therefore, the problem can be defined by the urban footprint that expands on …

Gpr75 Deficiency Attenuates High Fat Diet-Driven Obesity And Glucose Intolerance, Sakib Hossain
NYMC Student Theses and Dissertations
Recently, a collaboration between Regeneron Pharmaceuticals and the Schwartzman-Garcia labs at New York Medical College published an exome sequencing study of individuals across the United Kingdom, United States, and Mexico which concluded that individuals possessing non-functioning, truncated mutations to the orphan g protein coupled receptor (GPCR), GPR75, had lower BMI and 54% reduced likelihood of obesity. The present study was undertaken to fully characterize the metabolic phenotype of Gpr75 deficient mice when fed a high fat diet (HFD) and explore potential mechanisms by which GPR75 activation links to increased adiposity and decreased glucose tolerance. After 14 weeks of HFD-feeding we …
