Science Lecture: Waves of Change: How Ocean Acidification is Reshaping Coral Reefs” at Stony Brook Southampton
December 4, 2015 @ 7:00 pm - 8:30 pmFree
The increase in dissolved seawater CO2, commonly referred to as ocean acidification, is directly threatening the persistence of coral reef ecosystems. The biological and physiological impacts of acidification have been well documented for many hermatypic corals; however, the potential effects on bioerosion processes remain largely unknown and underappreciated by both scientists and the general public. Acidification will likely modify the direct interactions between corals and bioeroders, such as boring sponges, with broad implications for the balance between growth and erosion in reef communities. The effects of acidification and temperature on the interaction between a boring sponge, Cliona varians, and a Caribbean coral, Porites furcata will be presented, along with a study of the bioeroding community response to acidification. The broad scale impacts of increased bioerosion will be discussed, and the lecture will explore how ocean acidification is reshaping coral reefs.
