Sentences with phrase «calcified shells»

This hinders the ability of organisms such as molluscs, sea urchins, coralline algae and cold - water corals to produce their calcified shells and skeletons, affecting their survival.

During the Ediacarans» latter days, the first tiny organisms with calcified shells began to populate the oceans.

These little organisms are central to the global carbon cycle, a role that could be disrupted if rising levels of atmospheric carbon dioxide and warming temperatures interfere with their ability to grow their calcified shells.

Most studies have concluded that sea animals with calcified shells or skeletons, such as starfish, will suffer as carbon dioxide from burning fossil fuels dissolves in the sea, making the water more acidic and destroying the calcium carbonate on which the creatures depend.

Not exact matches

This process, termed ocean acidification, makes it energetically more costly for calcifying organisms to form their calcareous shells and skeletons.

Additionally, calcifying organisms incorporate the inorganic carbon in their calcium carbonate shells directly.

Exactly these elements are needed by calcifying organisms — plankton, mussels, snails, crabs or corals — to build their shells and skeletons.

The shells of the eggs appeared heavily calcified and were abnormally thick.

On the effects on calcification: It is expected that calcifying organisms will find it more difficult to produce and maintain their shells and hard structures.

«Southern Ocean acidification via anthropogenic CO2 uptake is expected to be detrimental to multiple calcifying plankton species by lowering the concentration of carbonate ion (CO32 − to levels where calcium carbonate (both aragonite and calcite) shells begin to dissolve.

«More acidic waters make it difficult for corals and other calcifying organisms, such as animals with shells, to form their skeletons, which are ultimately responsible for building the physical structure of the reef,» says Australian Institute of Marine Science research scientist, Dr Janice Lough.»

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.

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).
