“…Cessation of movement (or moribundity) is frequently used as an indicator of mortality in ecotoxicology studies and is practical with fish and sometimes cnidarians (e.g. jellyfish ephyrae bell pulsing) but is not applicable to N. vectensis [35]. In addition, organisms which appear dead, may recover when placed in clean control media water.…”

I dedicate this dissertation to my parents. Without their love, patience, support, understanding, and a poke every now and then, I never would have gotten through this. You have always been there for me and encouraged me to push for what I wanted. Well, it is about time isn't it? And R…thank you for being there for me. Thank you for your kindness, sharing your humor and reminding me to laugh, and listening to all of my stories and graduate school woes. You are the best. v ACKNOWLEDGMENTS This dissertation was possible thanks to the help and support of many people. First, I would like to thank Dr. Rand for giving me a position in his lab and allowing me to talk him into supporting me as a PhD student. My dissertation committee, Drs. Michael Heithaus, Jose (Chema) Eirin-Lopez, Heather Bracken-Grissom, and Kevin Boswell provided valuable guidance. A large portion of my graduate research was supported through a contract with British Petroleum but I also received a teaching assistantship from the Biology Department and a fellowship from the NSF CREST CAChE program. Drs. Todd Crowl and Rita Teutonico have done an awesome job bringing students together from a variety of fields and supporting their work and collaboration. We appreciate all your efforts. Also, thank you to my parents. Thank you for your support and encouragement and gentle prodding at times. I couldn't have done it without you, and I am thankful for everything you do. Thank you to a long list of everyone else at FIU who helped me at some time:

Polyps of the Jellyfish Aurelia aurita Are Unaffected by Chronic Exposure to a Combination of Pesticides

Pesticides are a major contaminant in coastal waters and can cause adverse effects in marine invertebrates such as jellyfish. Most studies have investigated short‐term responses of organisms to unrealistically high concentrations of pesticides; however, chronic exposure to persistent low concentrations, which are more likely to occur in the environment, are rarely analyzed. We tested the response of polyps of the moon jellyfish Aurelia aurita to environmental concentrations of the herbicide atrazine and the insecticide chlorpyrifos, individually and in combination, over 9 wk. We hypothesized that exposure to individual pesticides would reduce rates of asexual reproduction and alter polyps' metabolite profiles, and that the results would be more severe when polyps were exposed to the combined pesticides. Polyps survived and reproduced (through budding) in all treatments, and no differences among treatments were observed. Proton nuclear magnetic resonance spectroscopy revealed no difference in profiles of polar metabolites of polyps exposed to the individual or combined pesticides. Our results suggest that A. aurita polyps are unaffected by chronic exposure to atrazine and chlorpyrifos at concentrations recommended as being protective by current Australian water quality guidelines.

Coral Ecotoxicological Data Evaluation for the Environmental Safety Assessment of Ultraviolet Filters

There is growing interest in the environmental safety of ultraviolet (UV) filters found in cosmetic and personal care products (CPCPs). The CPCP industry is assessing appropriate environmental risk assessment (ERA) methods to conduct robust environmental safety assessments for these ingredients. Relevant and reliable data are needed for ERA, particularly when the assessment is supporting regulatory decision‐making. In the present study, we apply a data evaluation approach to incorporate nonstandard toxicity data into the ERA process through an expanded range of reliability scores over commonly used approaches (e.g., Klimisch scores). The method employs an upfront screening followed by a data quality assessment based largely on the Criteria for Reporting and Evaluating Ecotoxicity Data (CRED) approach. The method was applied in a coral case study in which UV filter toxicity data was evaluated to identify data points potentially suitable for higher tier and/or regulatory ERA. This is an optimal case study because there are no standard coral toxicity test methods, and UV filter bans are being enacted based on findings reported in the current peer‐reviewed data set. Eight studies comprising nine assays were identified; four of the assays did not pass the initial screening assessment. None of the remaining five assays received a high enough reliability score ( R n ) to be considered of decision‐making quality (i.e., R1 or R2). Four assays were suitable for a preliminary ERA (i.e., R3 or R4), and one assay was not reliable (i.e., R6). These results highlight a need for higher quality coral toxicity studies, potentially through the development of standard test protocols, to generate reliable toxicity endpoints. These data can then be used for ERA to inform environmental protection and sustainability decision‐making. Environ Toxicol Chem 2021;40:3441–3464. © 2021 Personal Care Products Council.
