Millennial-scale ocean acidification and late Quaternary decline of cryptic bacterial crusts in tropical reefs

Ocean acidification by atmospheric carbon dioxide has increased almost continuously since the last glacial maximum (LGM), 21 000 years ago. It is expected to impair tropical reef development, but effects on reefs at the present day and in the recent past have proved difficult to evaluate. 212 more words

The future of coral reef algae: how ocean acidification, elevated temperatures and nutrient enrichment affect algae

Benthic algae are an important part of coral reef ecosystems, providing food and shelter for many organisms. However, algae are also powerful competitors for space. Their interactions with reef-building corals are of particular interest, as coral reef health is influenced by both herbivores and the dynamics of coral-algal interactions. 796 more words

Stimulated bacterial growth under elevated pCO2: results from an off-shore mesocosm study

Marine bacteria are the main consumers of freshly produced organic matter. Many enzymatic processes involved in the bacterial digestion of organic compounds were shown to be pH sensitive in previous studies. 282 more words

Intertidal epilithic bacteria diversity changes along a naturally occurring carbon dioxide and pH gradient

Intertidal epilithic bacteria communities are important components of coastal ecosystems, yet few studies have assessed their diversity and how it may be affected by changing environmental parameters. 222 more words
