Marine microbial gene abundance and community composition in response to ocean acidification and elevated temperature in two contrasting coastal marine sediments

Marine ecosystems are exposed to a range of human-induced climate stressors, in particular changing carbonate chemistry and elevated sea surface temperatures as a consequence of climate change. 292 more words

The survival, recovery, and diversification of metazoan reef ecosystems following the end-Permian mass extinction event

The Triassic Period records important ecological transitions in the aftermath of the end-Permian mass extinction and is a key interval in the evolution of modern coral reefs. 351 more words

Ocean acidification of a coastal Antarctic marine microbial community reveals a critical threshold for CO2 tolerance in phytoplankton productivity

High-latitude oceans are anticipated to be some of the first regions affected by ocean acidification. Despite this, the effect of ocean acidification on natural communities of Antarctic marine microbes is still not well understood. 320 more words

Solar UVR sensitivity of phyto- and bacterioplankton communities from Patagonian coastal waters under increased nutrients and acidification

The effects of ultraviolet radiation (UVR) under future expected conditions of acidification and increase in nutrient inputs were studied on a post-bloom phytoplankton and bacterioplankton community of Patagonian coastal waters. 280 more words

Faunal succession and geochemical analysis of carbonate facies changes along the late Permian mass extinction boundary in the Nanpanjiang Basin, South China: a potential argument for ocean acidification and its implications

The late Permian mass extinction is considered the largest extinction event in Earth’s history with over 90% of marine and 70% of terrestrial species becoming extinct as a result (Lehrmann et al., 2015). 157 more words

Ocean acidification changes the structure of an Antarctic coastal protistan community

Antarctic near-shore waters are amongst of the most vulnerable in the world to ocean acidification. Microbes occupying these waters are critical drivers of ecosystem productivity, elemental cycling and ocean biogeochemistry, yet little is known about their sensitivity to ocean acidification. 239 more words

Low pH reduces the virulence of black band disease on Orbicella faveolata

Black band is a deadly coral disease found worldwide, which may become more virulent as oceanic conditions continue to change. To determine the effects of climate change and ocean acidification on black band disease virulence, Orbicella faveolata corals with black band were exposed to different temperature and pH conditions. 101 more words
