Bioerosion matters – trends of coral reef carbonate cycling by sponges : SESE and Oceans Institute Seminar Other events...
Bioeroding sponges are the most important internal bioeroders on many coral reefs, but are often overlooked because of their cryptic habit. In comparison with extensive research into reef calcification, bioerosion in general is critically understudied, and the mechanisms of reef degradation by sponges are still not fully understood. While calcifying organisms are routinely surveyed in monitoring programs, the distribution and abundance of bioeroding sponges is rarely assessed. We do not have comprehensive data on the rate of bioerosion by sponges through time or on sponge bioerosion rates before and after disturbance events. However, it does appear that environmental changes will critically shift the natural balance between reef accretion and bioerosion. This presentation will summarise what is known about the biology of bioeroding sponges and address questions regarding their likely impacts on coral reef health. It will examine the effects they are currently having on reefs and whether these effects are expected to change through time. A special focus will be provided on recent results on effects of ocean acidification. The talk will also discuss how we can control and monitor sponge bioerosion and what research is needed to help us protect our reefs. It will further address important knowledge gaps, create greater awareness, provide useful tools for future studies and encourage research into this ecologically significant group.
