ScienceMag.org: To the untrained eye, real animal sponges may seem as boring as synthetic kitchen sponges. But the evolution of these highly porous creatures has long been a mystery, with major implications for the early evolution of animals. 56 more words


Ocean acidification enhances the bioerosion of a common coral reef sponge: implications for the persistence of the Florida Reef Tract

The increase in anthropogenic carbon dioxide in seawater, termed ocean acidification (OA), depresses calcification rates of coral and algae, and may contribute toward reef ecosystem degradation. 219 more words


Acidification effects on biofouling communities: winners and losers

How ocean acidification affects marine life is a major concern for science and society. However, its impacts on encrusting biofouling communities, that are both the initial colonizers of hard substrata and of great economic importance, are almost unknown. 217 more words

Natural volcanic CO2 seeps reveal future trajectories for host–microbial associations in corals and sponges

Atmospheric carbon dioxide (CO2) levels are rapidly rising causing an increase in the partial pressure of CO2 (pCO2) in the ocean and a reduction in pH known as ocean acidification (OA). 263 more words
