Genetic and morphological divergence in the warm-water planktonic foraminifera genus Globigerinoides. [PDF]

PLoS One, 2019
The planktonic foraminifera genus Globigerinoides provides a prime example of a species-rich genus in which genetic and morphological divergence are uncorrelated.

Influence of surface ocean density on planktonic foraminifera calcification. [PDF]

Sci Rep, 2019
This study provides evidence that ambient seawater density influences calcification and may account for the observed planktonic foraminifera shell mass increase during glacial times.

The Foraminiferal Response to Climate Stressors Project: Tracking the Community Response of Planktonic Foraminifera to Historical Climate Change

Frontiers in Marine Science, 2022
Planktonic Foraminifera are ubiquitous marine protozoa inhabiting the upper ocean. During life, they secrete calcareous shells, which accumulate in marine sediments, providing a geological record of past spatial and temporal changes in their community ...

ForCenS, a curated database of planktonic foraminifera census counts in marine surface sediment samples. [PDF]

Sci Data, 2017
Census counts of marine microfossils in surface sediments represent an invaluable resource for paleoceanography and for the investigation of macroecological processes. A prerequisite for such applications is the provision of data syntheses for individual

Eocene planktonic foraminifera from the north Eastern Desert, Egypt: Biostratigraphic, paleoenvironmental and sequence stratigraphy implications

, 2021
The Eocene succession at Beni Suef -El Zaafarana District in north Eastern Desert is rich in planktonic foraminiferal assemblages. The main objectives of this work are to use the planktonic foraminifera to recognize the biostratigraphy for the Middle ...

Sixty-one thousand recent planktonic foraminifera from the Atlantic Ocean. [PDF]

Sci Data, 2018
Marine microfossils record the environmental, ecological, and evolutionary dynamics of past oceans in temporally expanded sedimentary archives. Rapid imaging approaches provide a means of exploiting the primary advantage of this archive, the vast number ...

Surface ocean metabarcoding confirms limited diversity in planktonic foraminifera but reveals unknown hyper-abundant lineages. [PDF]

Sci Rep, 2018
Since the advent of DNA metabarcoding surveys, the planktonic realm is considered a treasure trove of diversity, inhabited by a small number of abundant taxa, and a hugely diverse and taxonomically uncharacterized consortium of rare species.

Calcification intensity in planktonic Foraminifera reflects ambient conditions irrespective of environmental stress [PDF]

Biogeosciences, 2013
Planktonic Foraminifera are important marine calcifiers, and the ongoing change in the oceanic carbon system makes it essential to understand the influence of environmental factors on the biomineralization of their shells.

Changes in biogeographic distribution patterns of southern mid-to high latitude planktonic foraminifera during the Late Cretaceous hot to cool greenhouse climate transition

Cretaceous research (Print), 2020
The biogeographic distribution of planktonic foraminifera from southern mid-to high latitudes region are discussed to identify links between species distribution patterns and the changes in Late Cretaceous climate.
