Round Goby, Neogobius Melanostomus, Abundance And Productivity In The Rocky Nearshore Zone Of Lake Michigan, Graceanne Kay Tarsa
Theses and Dissertations
Few organisms are well adapted to efficiently feed on invasive dreissenid mussels, a dominant primary consumer in Lake Michigan and other lower Great Lakes. As a result, these mussels represent a potential trophic dead-end. However, round gobies (Neogobius melanostomus), an invasive species introduced to the Great Lakes region at the end of the 20th century, possess several adaptive advantages that allow them to make dreissenid mussels a significant portion of their diet. Since their invasion, round gobies have become the predominant shallow nearshore fish in Lake Michigan and their success, along with the success of dreissenid mussels, has caused major …
Transcriptomics And Toxcast Data Identify Bioeffects In Zebrafish Embryos Exposed To Chemical Mixtures In An Effluent-Dominated Stream, Emma Meade
Theses and Dissertations
Wastewater treatment plant (WWTP) effluent-dominated streams provide critical habitat for aquatic organisms but also continually expose them to complex mixtures of pharmaceuticals and other contaminants of emerging concern (CECs) that can potentially impair growth, behavior, and reproduction. Limited toxicity data on the adverse biological impacts of in vivo exposure to these mixtures make it difficult to assess risk for aquatic organisms, particularly with respect to pharmaceuticals whose designed bioactivity often extends beyond conventionally monitored biological pathways. To address this knowledge gap, the goal of this thesis was to identify biomarkers of exposure to complex CEC mixtures relevant to specific chemicals …
