Ammonia tepida is a benthic foraminifer living in the sediment of brackish waters. It is very similar to Ammonia beccarii , but the latter lives on the surface of red algae. [2] Once considered a globally widespread taxon, a recent genetic and morphological study has revealed that many of what were once considered members of A. tepida in fact represent other species of Ammonia, primarily Ammonia veneta , with true specimens of A. tepida only being found in Atlantic waters, off the coast of the Americas.

Ecology

Ammonia tepida is found in the sediment of brackish waters. It is able to tolerate a wide range of temperatures and degrees of salinity, as well as to survive severe environmental conditions. As it is easy to keep in the laboratory, being able to reproduce both asexually and sexually without problem, it considered an ideal organism for laboratory studies. [4]

The diet of A. tepida consists mainly of other microorganisms. Algae form about 80–90% of its diet and the remaining is composed by bacteria. [5] Laboratory experiments showed that it may also prey on small animals, such as nematodes, copepods and mollusk larvae. [6]

Foraminifera are single-celled organisms, members of a phylum or class of Rhizarian protists characterized by streaming granular ectoplasm for catching food and other uses; and commonly an external shell of diverse forms and materials. Tests of chitin are believed to be the most primitive type. Most foraminifera are marine, the majority of which live on or within the seafloor sediment, while a smaller number float in the water column at various depths, which belong to the suborder Globigerinina. Fewer are known from freshwater or brackish conditions, and some very few (nonaquatic) soil species have been identified through molecular analysis of small subunit ribosomal DNA.

<span class="mw-page-title-main">Carterinida</span> Order of single-celled organisms

Carterinida is an order of multi-chambered foraminifera within the Globothalamea. Members of this order form hard tests out of thin calcite rods known as spicules, which are held together by a proteinaceous matrix. As of August 2023, the order contains a single family, Carterinidae.

Elphidium williamsoni is a species of foraminiferans belonging to the family Elphidiidae. Elphidium williamsoni is found in abundance around the coasts of the UK, predominantly in the lower end of the coast.

The Cassidulinacea is a superfamily of benthic amoeboid foraminifera in the order Rotaliida that has been extant from the Paleocene down to the present. Tests are composed of secreted, optically radial or granular, perforate calcite with chambers biserially coiled at least in the early part, Apertures are usually an interiomarginal slit, but may become terminal and may have secondary features.

Globigerinoides is an extant genus of shallow-water planktonic foraminifera of family Globigerinidae. First appearing in the Oligocene these foraminifera are found in all modern oceans. Species of this genus occupy the euphotic zone, generally at depths between 10-50m, in waters which cover a range of salinities and temperatures. They are a shorter lived species, especially when compared to Globorotalia genus. As a genus Globigerinoides is widely used in various fields of research including biostratigraphy, isotope geochemistry, biogeochemistry, climatology, and oceanography.

"Monothalamea" is a grouping of foraminiferans, traditionally consisting of all foraminifera with single-chambered tests. Recent work has shown that the grouping is paraphyletic, and as such does not constitute a natural group; nonetheless, the name "monothalamea" continues to be used by foraminifera workers out of convenience.

Global paleoclimate indicators are the proxies sensitive to global paleoclimatic environment changes. They are mostly derived from marine sediments. Paleoclimate indicators derived from terrestrial sediments, on the other hand, are commonly influenced by local tectonic movements and paleogeographic variations. Factors governing the Earth's climate system include plate tectonics, which controls the configuration of continents, the interplay between the atmosphere and the ocean, and the Earth's orbital characteristics. Global paleoclimate indicators are established based on the information extracted from the analyses of geologic materials, including biological, geochemical and mineralogical data preserved in marine sediments. Indicators are generally grouped into three categories; paleontological, geochemical and lithological.
