Evolutionary Expansions And Neofunctionalization Of Ionotropic Glutamate Receptors In Cnidaria, Ellen G. Dow
Evolutionary Expansions And Neofunctionalization Of Ionotropic Glutamate Receptors In Cnidaria, Ellen G. Dow
FIU Electronic Theses and Dissertations
Reef ecosystems are composed of a variety of organisms, transient species of fish and invertebrates, microscopic bacteria and viruses, and structural organisms that build the living foundation, coral. Sessile cnidarians, corals and anemones, interpret dynamic environments of organisms and abiotic factors through a molecular interface. Recognition of foreign molecules occurs through innate immunity via receptors identifying conserved molecular patterns. Similarly, chemosensory receptors monitor the environment through specific ligands. Chemosensory receptors include ionotropic glutamate receptors (iGluRs), transmembrane ion channels involved in chemical sensing and neural signal transduction. Recently, an iGluR homolog was implicated in cnidarian immunological resistance to recurrent infections of …

Quantifying Anthropogenic Indicators And Changes In Dissolved Organic Matter In Coastal Urban Aquatic Ecosystems Exposed To High Tidal Flooding, Gonzalo E. Eyzaguirre

Sea-level rise is causing an increase in tidal flooding in coastal urban areas. Extreme high tides, also known as king tides, are peak tide moments in which tidal amplitude is increased and shallow groundwater flows from the underlying water table are introduced. During tidal flooding in urban areas, accumulated anthropogenic indicators of different water sources are released from groundwater to surface waters, but how these tidal events affect the contributions of different water sources to urban flood waters is uncertain. We quantified tracers of anthropogenic origin including fluoride, fecal coliform bacteria, as well as dissolved organic carbon (DOC) concentrations and …
