Heavy metals contamination and distribution of benthic foraminifera from the Red Sea coastal area, Jeddah, Saudi Arabia

Oceanologia, 2015
The distribution of benthic foraminifera was studied in two stations in the coastal area, located around Jeddah, Red Sea coast, Saudi Arabia. Thirty-three species belonging to 15 genera, 14 families and three suborders were recorded in twenty samples ...

Biological evolution of the carbonate platform of the Taleh Zang Formation in Kermanshah region [PDF]

Journal of Stratigraphy and Sedimentology Researches, 2021
In this paper, the biological evolution of the carbonate platform of the Taleh Zang Formation with Paleocene age in the Kermanshah region has been investigated in two stages (time interval) concentrating on fossil debris (such as algae, corals, and ...

Unique Habitat for Benthic Foraminifera in Subtidal Blue Holes on Carbonate Platforms

Frontiers in Ecology and Evolution, 2021
Dissolution of carbonate platforms, like The Bahamas, throughout Quaternary sea-level oscillations have created mature karst landscapes that can include sinkholes and off-shore blue holes.

The role of benthic foraminifera in the benthic nitrogen cycle of the Peruvian oxygen minimum zone [PDF]

Biogeosciences, 2013
The discovery that foraminifera are able to use nitrate instead of oxygen as an electron acceptor for respiration has challenged our understanding of nitrogen cycling in the ocean.

Multiple Ecological Parameters Affect Living Benthic Foraminifera in the River-Influenced West-Central Bay of Bengal

Frontiers in Marine Science, 2021
The huge riverine influx and associated processes decrease the ambient salinity, stratify the water column, modulate the oxygen-deficient zone, and are also responsible for the recent acidification in the Bay of Bengal.

Renewal of planktonic foraminifera diversity after the Cretaceous Paleogene mass extinction by benthic colonizers

Nature Communications, 2022
Planktonic foraminifera are key to understanding paleoclimate and plankton evolution, but their origins are unclear. Here, the authors use a molecular clock to suggest that benthic foraminifera dispersed in plankton and renew planktonic foraminifera ...

Benthic Foraminifera of the Upper Jurassic Platform Carbonate Sequence in the Aydincik (Içel) Area, Central Taurides, S Turkey

Geologia Croatica, 2001
The Upper Jurassic sequence of the Aydincik (Içel) area consists of platform limestones which were deposited in a subtidal, restricted lagoon environment. Stratigraphic distribution of benthic foraminifera and calcareous algae, examined in thin-sections,

Biostratigraphy and paleoenvironment of Maastrichtian foraminiferal assemblages from a succession located NW of Tuxtla Gutiérrez, Chiapas (SE Mexico)

Revista Mexicana de Ciencias Geológicas, 2021
During the Maastrichtian, two lithostratigraphic units were deposited in the central Chiapas region; the Ocozocoautla and Angostura formations. The first unit crops out northwest of the city of Tuxtla Gutiérrez in central Chiapas.

Pliocene and Pleistocene chronostratigraphy and paleoenvironment of the Central Arctic Ocean, using deep water agglutinated foraminifera [PDF]

, 1998
Deep-water agglutinated foraminifera (DWAF) were studied from Cores PS2177-5, PS2200-5, PS2212-3 and PS2185-6; from the R/V POLARSTERN ARK-VIII/3 Cruise in the central Arctic Ocean.
