Before you start: Symbiodinium are dinoflagellates that are housed in take down building red coral tissues. The importance of Symbiodinium in reef formation is to provide energy for corals through photosynthesis for successful maturation (Anderson 2009). Not only are corals one of the oldest ecosystems on the planet but they also support several species with shelter and viands (Pandey, 2011). Corals in return protect and provide a food rich environment for Symbiodinium (Anderson 2009).
Question: Symbiotic relationships between coral and Symbiodinium are necessary for the subsistence of coral. Coral bl each(prenominal)ing is a result of the cut down physiological function of Symbiodinium. Are the periodic low saltwater temperatures, due to Arctic cold fronts, adversely impacting a all-important(a) element of the corals of the Florida Keys?
Experiment: Dustin W. Kemp and others* conducted their research to prove whether low brine temperatures negatively affect the Symbiodinium. They assert that these low temperatures reduce the cellphone density, light chlorophyll a content and triggering photoinhibition in Symbiodinium. This sample was conducted on the Caribbean reef-building corals, Monotastraea faveolata, Siderastrea siderea, and Porites astreoides.
Mimicking the temperature of two past cold fronts (12-20 °C) the Keys experienced, mass wipeouts of many an(prenominal) corals occurred. Coral pieces were collected and held in temperature-controlled tanks to observe the physiological responses of the corals. Tissues were examined, chlorophyll a extracted, and Symbiodinium genome and density identified.
