Sentences with phrase «form calcium carbonate skeletons»

In a separate study, conducted at Australia's ARC Centre of Excellence for Coral Reef Studies, researchers found that organisms that form calcium carbonate skeletons have a mechanism to cope with more acidic environments.

A year - long laboratory study of coccolithophores — an important type of phytoplankton — found they remained capable of forming their calcium carbonate skeletons even in warmer, more acidic water.

«The marine calcifiers that live in polar regions are particularly vulnerable to the effects of ocean acidification, a progress which is reducing their mineralization capacity and forming calcium carbonate (CaCO3) skeletons used as a protective and supporting structure against predators» says Blanca Figuerola, main author of the scientific study.

Acidic waters are corrosive to many larval shellfish, and they reduce the amount of available carbonate, which some marine organisms need to form calcium carbonate shells or skeletons.

But they conclude that marine organisms with skeletons made of high - magnesium calcite may be especially susceptible to ocean acidification because this form of calcium carbonate dissolves more easily than others.

The researchers also observed evidence that the unstable precursors eventually crystallized into aragonite, the stable form of calcium carbonate that makes up mature coral skeletons.

Aragonite is a mineral form of calcium carbonate (CaCO3) that is often used by marine species to form skeletons and shells.

Oysters and other shellfish, including clams and lobsters, and a host of sea creatures that include plankton and corals, need calcium carbonate minerals to form their shells and skeletons.

Acidification increases the corrosiveness of the water and is also driving a decline in the amount of carbonate ion, needed to make aragonite and calcite, two forms of calcium carbonate that many marine organisms use to build their shells and skeletons.

This is significant because coral reefs and shelled marine organisms need carbonate ions to form the lime or calcium carbonate that composes their skeletons and shells.

Aragonite is a form of calcium carbonate that many marine animals use to build their skeletons and shells.

Many organisms require supersaturated conditions to form sufficient calcium carbonate shells or skeletons, and biological calcification rates tend to decrease in response to lower carbonate ion concentrations, even when the ambient seawater is still supersaturated.

This second reaction is important because reduced seawater carbonate ion concentrations decrease the saturation levels of calcium carbonate (CaCO3), a hard mineral used by many marine microbes, plants and animals to form shells and skeletons.

Calcite - A calcium carbonate (limestone) mineral, used by shell - or skeleton - forming, calcifying organisms such as foraminifera, some macroalgae, lobsters, crabs, sea urchins and starfish.

Coral skeletons are composed of aragonite, or calcium carbonate in its crystalline form.

Aragonite - A calcium carbonate (limestone) mineral, used by shell - or skeleton - forming, calcifying organisms such as corals (warm - and coldwater corals), some macroalgae, pteropods (marine snails) and non-pteropod molluscs such as bivalves (e.g., clams, oysters), cephalopods (e.g., squids, octopuses).

Increasingly acidic waters due to buildup of atmospheric carbon dioxide is diminishing Great Barrier Reef corals, robbing sharks of their predatory senses, and hindering sea stars and other calcifiers in their ability to store calcium carbonate, which is crucial in forming their protective skeletons.
