“…This, in turn, affects different ecological processes (e.g., disruption in food webs, nutrient cycling, and energy flow) with a widespread effect on the overall ecosystem. Globally, oxygen levels in the ocean have decreased approximately 2% since the 1950s and are expected to decrease another 3-5% by the year 2100 due to climate change caused by anthropogenic activities (Bakun, 2017;Poppick, 2019;Goodkin and Pullen, 2019;Altieri et al, 2021;Triana et al, 2022). Hypoxia affects the biodiversity of the ocean by sublethal stresses, including reproductive and habitual complications and subsequently affecting species networks in each environment (Vaquer-Sunyar and Duarte, 2008;Khan et al, 2018).…”

Hypoxia as a stressor has physiological implications that have been a focal point for many physiological studies in recent years. In some studies, hypoxia had large effects on the organ tissue degeneration, which ultimately effects multiple ecological processes. These organ tissue studies played a part in the development of new fields like neurocardiology, a specialty that studied the relationship between the brain and the heart. This thesis focuses on how hypoxia-induced cardiac arrest alters the amounts of GLYT2, a glycine reuptake transporter, in the central nervous system of zebrafish, Danio rerio. At 7 days post-fertilization (dpf), zebrafish were exposed to acute, severe hypoxia until they lost equilibrium, and minutes later, subsequent cardiac arrest occurred. Zebrafish were then placed into recovery groups to measure the GLYT2 levels at multiple points in zebrafish recovery. Fish were then sacrificed, and their brains dissected. Using immunofluorescence, the outer left optic tectum of the zebrafish was imaged, and mean image pixel fluorescent intensity was taken. There were significant changes (one-way ANOVA) in the levels of GLYT2 compared to that of the control groups during the course of recovery. GLYT2 levels continued to rise through the 24-hour recovery mark but did not show significant difference after 3 hours of recovery. This suggest that GLYT2 levels increased rapidly in the first 3 hours of recovery and continued to increase through 24 hours at a slower rate. Changes in GLYT2 levels may affect motor and sensory information, movement, visualization, and audition in these zebrafish. Further research should be conducted to determine how long it takes for GLYT2 levels to return to baseline, as well as behavioral measurements through each recovery period as it relates to glycine function.
