Becoming The Donkey Derby’S ‘Karen’: A Humane Educator’S Autoethnographic Journey Toward Anti-Speciesist Communication, Jesika Keener

Antioch University Dissertations & Theses

Language not only carries oppression as an educative force, but research indicates that language is inherently speciesist and highly pervasive (Ethical Globe, 2021; Guevara Labaca, 2017; Hamlett, 2024; Leach et al., 2023). However, the ontological commitment to speciesism is historically foundational, which makes the total eradication of speciesist communication only viable through an unemerged hypothetical future society (Kahn, 2011). For the possibilities of such a world to come into being, pivotal steps must first be taken to critically engage with the communicated forms of speciesism in order to better understand it and actively resist its reproduction—with the aspiration for this …

The Role Of Heterotrophy In The Response Of Oculina Arbuscula To Ocean Acidification, Alejandra E. Daniel

College of Graduate Studies: Theses & Dissertations

On both tropical and temperate reefs, the calcium carbonate skeletons produced by scleractinian corals provide habitat that supports a high biodiversity of fishes and invertebrates. Ocean acidification (OA), driven by excess anthropogenic CO₂ uptake, causes declines in seawater pH and carbonate ion concentration and can compromise coral calcification by causing increased energetic demands. Deciphering how corals meet this increased energetic demand is critical to predicting their future persistence. Oculina arbuscula is a facultatively symbiotic temperate coral common on subtropical reefs of the South Atlantic Bight. This coral has demonstrated calcification resilience to reduced pH conditions in both symbiotic and …

Lactate's Role In Appetite Suppression, Seth Mccarthy

Theses and Dissertations (Comprehensive)

Once considered metabolic waste produced during exercise, lactate is now known to have diverse roles in biology. Muscle-derived lactate can travel through the bloodstream and be taken up by other tissues and i) oxidized, ii) converted to glucose via gluconeogenesis, or iii) bind to its receptor to trigger molecular signaling cascades. Lactate has been described as a “myokine” capable of inter-organ crosstalk and compelling evidence demonstrates lactate’s role as a signalling molecule in pathways related to the regulation of appetite. The purpose of this dissertation was to further elucidate lactate’s role in appetite regulation using series of studies aimed at …

Timing Of Migration And Seasonal Movements Of Arctic Grayling (Thymallus Arcticus) In Relation To Water Temperature In The Kakisa River And Upper Mackenzie River, Nwt: Results From An Acoustic Telemetry Study., Levi Snook

Theses and Dissertations (Comprehensive)

Arctic grayling (Thymallus arcticus) are a cold-water salmonid that inhabit waterbodies throughout the circumpolar regions of the northern hemisphere. In the last decade, Ka'a'gee Tu First Nation members as well as local sport fishers, have observed lower catches of Arctic grayling during their annual spawning run in the Kakisa River, NWT. Many potential causes of this decline have been hypothesized including climate change and over harvesting. Outside of the general annual spawning activity in the headwaters of the Kakisa River, the ecology of the population, including post-spawn habitat use and migratory patterns, remained understudied. To address these knowledge gaps, acoustic …

Husbandry Of Jellyfish And Ctenophores: Why Gelatinous Forms Thrive In Their Natural Habitat And Yet Often Struggle To Survive In Aquaria, Regina Garza Ramirez

Undergraduate Theses and Capstone Projects

Recent observations in the behaviors of several gelatinous forms in the wild have demonstrated that human impacts to their environment have likely accelerated growth of their populations tremendously. Interestingly enough, population growth of jellyfish and ctenophores in aquariums and artificial habitats is less often observed under controlled conditions, while they often bloom in rapidly changing environments of nature. Seeking the knowledge of aquarists and researchers that have worked directly with gelatinous animals through interviews, and documenting the experiences of each individual, allowed acquisition of data that can be used to compare the reproductive success of these animals in captivity and …

Parasitism By The Twisted-Winged Parasite Xenos Peckii (Strepsiptera), And Its Effects On The Ovary Development In Their Host Paper Wasp, Polistes Metricus (Hymenoptera), Alex K. Snyder

College of Graduate Studies: Theses & Dissertations

Strepsiptera are generally described as parasitic castrators as they cause the reproductive death of the hosts. In southeast Georgia, only a handful of paper wasps are hosts for twisted-winged parasites. One such species, Polistes metricus, is parasitized by a twisted-winged parasite, Xenos peckii. Previous studies document that host survivorship at most developmental stages was not largely influenced by the presence of X. peckii. To determine if X. peckii can affect their host’s ability to survive and reproduce, we dissected P. metricus to determine ovary development and the presence of X. peckii parasites. Parasite presence had no effect on the host’s …
