Context examples:
Anthropogenic carbon dioxide gas released into the atmosphere is also making sea water more acidic, affecting the calcification of coral and invertebrates, and so decreasing the habitat and food of reef-associated fish.
(Pacific island fish migrating to cooler seas, SciDev.Net)
Although one overarching conclusion of ocean acidification studies is that different species respond differently to elevated CO2 conditions, similar results have been reported in studies with different coral reef species.
(Fish larvae lose their way to safety in acidified oceans, SciDev.Net)
A record of climatic events found by examining the natural environment (tree rings, coral growth bands, layers of ice in glaciers).
(Natural climate record, NOAA Paleoclimate Glossary)
The absorption alters the water's chemistry, lowering its pH and reducing the amount of available carbonate, which organisms such as corals and pteropods (mollusks) use to construct their calcium carbonate shells.

Emerging fungal pathogens pose a greater threat to biodiversity than any other parasitic group, scientists say, causing population declines of amphibians, bats, corals, bees and snakes.
(Amphibians can acquire resistance to deadly fungus, NSF)
An environmental stress indicator for coral; if conditions for corals are not optimum, the corals will expel the algae that live among the living polyps, therefore giving the colony a bleached appearance.
(Coral bleaching, NOAA Paleoclimate Glossary)
The study was conducted at the NSF Kellogg Biological Station Long-Term Ecological Research site, one of 28 NSF LTER sites around the world in ecosystems from grasslands to forests, coral reefs to the open sea.
