This implies that that cave foraminifera can be useful paleohydrogeologic, paleoclimatic, and Quaternary sea-level proxies. A reduction in dissolved oxygen availability in marine habitats is among the predicted consequences of increasing global temperatures. An understanding of past oxygenation is critical for predictions of future changes in the extent and distribution of oxygen minimum zones (OMZs).

Foraminifera ('hole bearers'), foraminifers or forams for short, are a large phylum of amoeboid protozoans (single celled) with reticulating   Species diversity: benthonic foraminifera in western North Atlantic Ecology and systematics of foraminifera in two Thalassia habitats, Jamaica, West Indies. 7 Aug 2010 Foraminifera are testate organisms, which means that they have shells (tests). The protoplasm covers the exterior of the test. The simplest shapes  25 Aug 2020 Modern Foraminifera are primarily marine organisms, but living individuals have been found in brackish, freshwater and even terrestrial habitats. The benthic foraminiferal community in a naturally CO2-rich coastal habitat of the as the southwestern Baltic Sea, where benthic foraminifera are abundant. All the observed specimens were fixed just after collection from their natural habitats allowing description of intact and healthy cells.

Foraminifera habitat

The majority of the species are benthic, and a further 40 morphospecies are planktonic. In marine environments, Foraminifera are either planktonic or benthic. Typically, Benthic Foraminifera are bottom dwellers and thus reside at the seafloor. Here, they can be found in such habitats as marshes and abyssal plains where they move about and feed using their pseudopodia. Foraminifera are found in all marine environments, they may be planktic or benthic in mode of life. The generally accepted classification of the foraminifera is based on that of Loeblich and Tappan (1964).

Foraminifera are aquatic organisms, found in both freshwater and marine environments. For example, Amphistegina gibbosa inhabit coral reefs and carbonate shelves. Species diversity is highest in tropical areas.
