<p class="MsoNormal"><b>Identifying Chemical Controls and Signatures of Coral Reef Health<o:p></o:p></b></p>
<p class="MsoNormal">The physiology and health of corals are intimately tied to the concentration and flux of<o:p></o:p></p>
<p class="MsoNormal">chemicals within their tissues and in the surrounding waters. Reactive oxygen species<o:p></o:p></p>
<p class="MsoNormal">(ROS) are a group of oxygen intermediates that are tightly regulated by organisms as<o:p></o:p></p>
<p class="MsoNormal">they can be both essential and detrimental. Our research has highlighted the potential<o:p></o:p></p>
<p class="MsoNormal">role for the ROS hydrogen peroxide to serve as an indicator of stress within corals and<o:p></o:p></p>
<p class="MsoNormal">other reef organisms, such as macroalgae. While identifying early-stage diagnostics of<o:p></o:p></p>
<p class="MsoNormal">organismal health is critical for assessing and predicting reef health, chemicals may also<o:p></o:p></p>
<p class="MsoNormal">provide a means of preserving and restoring reefs. For instance, metal micronutrients<o:p></o:p></p>
<p class="MsoNormal">are essential for a suite of metalloenzymes and metabolic processes involved in growth<o:p></o:p></p>
<p class="MsoNormal">and immunity in coral reef organisms. Yet, corals often exist in oligotrophic regions<o:p></o:p></p>
<p class="MsoNormal">typified by low macro- and micro-nutrients. We are therefore researching the potential<o:p></o:p></p>
<p class="MsoNormal">to increase coral growth and resilience via metal micro-nutrient supplementation. We<o:p></o:p></p>
<p class="MsoNormal">are creating recruitment and growth substrates specifically formulated with mineral<o:p></o:p></p>
<p class="MsoNormal">mixtures that will release nutrients at optimal rates. We hope that by designing novel<o:p></o:p></p>
<p class="MsoNormal">monitoring tools and nature-inclusive substrates we can contribute to the protection<o:p></o:p></p>
<p class="MsoNormal">and restoration of coral reef ecosystems.<o:p></o:p></p>
