A deep-sea agglutinated foraminifer tube constructed with planktonic foraminifer shells of a single species [PDF]

Journal of Micropalaeontology, 2018
Abstract. Agglutinated foraminifera are marine protists that show apparently complex behaviour in constructing their shells, involving selecting suitable sedimentary grains from their environment, manipulating them in three dimensions, and cementing them precisely into position.

Foraminiferal marker taxa and their correlation potential for definition of the lower Serpukhovian boundary in the Urals

Литосфера, 2020
Research subject. The choice of the marker and the GSSP (Global Boundary Stratotype Section and Point) of the base of the Serpukhovian is currently one of the most urgent tasks of international stratigraphy.

Nitrate storage and dissimilatory nitrate reduction by eukaryotic microbes

Frontiers in Microbiology, 2015
The microbial nitrogen cycle is one of the most complex and environmentally important element cycles on Earth and has long been thought to be mediated exclusively by prokaryotic microbes.

Response of Pelagic Calcifiers (Foraminifera, Thecosomata) to Ocean Acidification During Oligotrophic and Simulated Up-Welling Conditions in the Subtropical North Atlantic Off Gran Canaria

Frontiers in Marine Science, 2018
Planktonic Foraminifera and thecosome pteropods are major producers of calcite and aragonite in the ocean and play an important role for pelagic carbonate flux.

Foraminifers associated with macroalgae on a wave-cut platform off Abu Qir coastal area, Egypt

Egyptian Journal of Aquatic Research, 2022
Since their earliest history, benthic foraminifers have diversified to inhabit a vast array of habitats, from semi-terrestrial to the deep-sea floor. Epiphytic foraminifers developed morphologies that have allowed them to inhabit macroalgal fronds and ...

Palaeobiogeographical constraints on the distribution of foraminifers and rugose corals in the Carboniferous Tindouf Basin, South Morocco

Journal of Palaeogeography, 2013
The northern flank of the Tindouf Syncline in southern Morocco exhibits a continuous, well exposed Carboniferous succession with limestones of Late Asbian to Early Bashkirian age containing rich and diverse foraminiferal and rugose coral assemblages ...
