Freshwater Foraminifera Biodiversity in New England (USA): Evaluation of Field Sites and a Botanical Garden [PDF]

open access: yesEcology and Evolution
Despite textbook definitions of foraminifera as marine organisms, foraminifera also occur in freshwater habitats, with first reports from ~150 years ago.

Biomineralization in perforate foraminifera [PDF]

open access: yesEarth-Science Reviews, 2014
In this paper, we review the current understanding of biomineralization in perforate foraminifera. Ideas on the mechanisms responsible for the flux of Ca2 + and inorganic carbon from seawater into the test were originally based on light and electron microscopic observations of calcifying foraminifera.

Environmental DNA sheds new insight on molecular adaptation of foraminifera to temperature from laboratory‐controlled culture experiment [PDF]

open access: yesEcology and Evolution
Foraminifera is the most important temperature proxy of the ocean on long time scales. However, the absence of temperature‐controlled experiments at different water depths hinders the advancement of paleotemperature reconstruction with foraminifera from ...

Mitochondrial cytochrome c oxidase subunit I (COI) metabarcoding of Foraminifera communities using taxon-specific primers [PDF]

open access: yesPeerJ, 2022
Foraminifera are a species-rich phylum of rhizarian protists that are highly abundant in most marine environments. Molecular methods such as metabarcoding have revealed a high, yet undescribed diversity of Foraminifera. However, so far only one molecular

COMMUNITY STRUCTURE OF BENTHIC FORAMINIFERA IN EASTERN WATERS OF SEGARA ANAK LAGOON IN CILACAP

open access: yesBiotropia: The Southeast Asian Journal of Tropical Biology, 2022
Benthic foraminifera are types of organisms that are sensitive to environmental changes, so they are often used as a bioindicator for aquatic environmental conditions.

Distribution patterns of foraminifera in paleotsunami layers: A review

open access: yesNatural Hazards Research, 2023
The presence of foraminifera is one of the main criteria for identifying paleotsunami. However, many paleotsunami studies reported the absence of foraminifera, even in the very young paleotsunami layers.

Smaller benthic foraminifera Analysis of Kudat Formation, Kudat, Sabah: Preliminary Interpretation. [PDF]

open access: yesGeological Behavior, 2017
Small benthic foraminifera have been fully extracted from the mudstone of Kudat Formation, Kudat, Sabah. The Kudat Formation comprise thick-bedded, quartzose to feldspathic, locally calcareous sandstone, an overall abundance of lignitic and ...

Biocalcification in porcelaneous foraminifera

open access: yeseLife, 2023
Living organisms control the formation of mineral skeletons and other structures through biomineralization. Major phylogenetic groups usually consistently follow a single biomineralization pathway. Foraminifera, which are very efficient marine calcifiers, making a substantial contribution to global carbonate production and global carbon sequestration ...

Origin of the foraminifera. [PDF]

open access: yesProceedings of the National Academy of Sciences, 1995
We report nuclear small-subunit rDNA sequences for two species of the benthic foraminifer Ammonia. Because of their abundance in present and past seas, the foraminifera are a very important group of organisms used in a wide range of geologic studies; however, the ancestry of this group was, until now, unknown.

Identifying organic-rich layers and reconstructing trophic levels in the Dalichai Formation in north Damghan [PDF]

open access: yesJournal of Stratigraphy and Sedimentology Researches, 2023
The Dalichai Formation in the Ahvanu section, north of Damghan city, with a thickness of 78 meters, comprises alternations of bluish-gray marls and limestones.
