Currently, atmospheric CO2 levels fluctuate around 390 ppm and continue to rise at an accelerating rate (Caldeira and Wickett 2003, 2005); projected scenarios indicate that levels will approach 450–600 ppm by 2050 and 750– 1,000 ppm by the end of the twenty-first century (IPCC 2007; gattuso and lavigne 2009). The resultant increase in dissolved seawater CO2(More)
Ocean acidification will disproportionately impact the growth of calcifying organisms in coral reef ecosystems. Simultaneously, sponge bioerosion rates have been shown to increase as seawater pH decreases. We conducted a 20-week experiment that included a 4-week acclimation period with a high number of replicate tanks and a fully orthogonal design with two(More)
Over the past decade, development along the northern coast of Jamaica has accelerated, resulting in elevated levels of sedimentation on adjacent reefs. To understand the effects of this development on sponge community dynamics, we conducted surveys at three locations with varying degrees of adjacent coastal development to quantify species richness,(More)
Coral rubble communities are an important yet often overlooked component of a healthy reef ecosystem. The organisms inhabiting reef rubble are primarily bioeroders that contribute to the breakdown and dissolution of carbonate material. While the effects of ocean acidification on calcifying communities have been well studied, there are few studies(More)
