Upper Eocene planktonic foraminifera from northern Saudi Arabia: implications for stratigraphic ranges [PDF]

Journal of Micropalaeontology, 2021
The Rashrashiyah Formation of the Sirhan Basin in northern Saudi Arabia contains diverse assemblages of planktonic foraminifera. We examined the biostratigraphy, stratigraphic range and preservation of upper Eocene planktonic foraminifera.

Planktonic foraminifera fluxes and their response to the Asian Monsoon: insights from the Maldives, Indian Ocean

Frontiers in Earth Science, 2023
This study describes seasonal changes in the fluxes of planktonic foraminifera in response to changes in environmental conditions during the Asian Monsoon.

A trait-based modelling approach to planktonic foraminifera ecology [PDF]

Biogeosciences, 2019
Despite the important role of planktonic foraminifera in regulating the ocean carbonate production and their unrivalled value in reconstructing paleoenvironments, our knowledge on their ecology is limited.

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 ...

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.

Planktonic foraminiferal turnover across the Cenomanian – Turonian boundary (OAE2) in the northeast of the Tethys realm, Kopet-Dagh Basin

Geologica Carpathica, 2016
Two Late Cenomanian – Early Turonian (C–T) intervals of the eastern part of the Kopet-Dagh basin, NE Iran have been investigated to evaluate the response of planktonic foraminifera to the geological event OAE2. The Gharesu and Taherabad sections with the

First report of modern planktonic foraminifera in the southeastern Arabian Gulf, with observations on the morphology and ecology of Neogallitellia vivans (Cushman) [PDF]

Journal of Micropalaeontology
This study reports the first documented occurrence of planktonic foraminiferal assemblages from core and grab samples collected from the United Arab Emirates (UAE) sector of the Arabian Gulf, specifically from offshore Abu Dhabi.

Planktonic foraminifera-derived environmental DNA extracted from abyssal sediments preserves patterns of plankton macroecology [PDF]

Biogeosciences, 2017
Deep-sea sediments constitute a unique archive of ocean change, fueled by a permanent rain of mineral and organic remains from the surface ocean. Until now, paleo-ecological analyses of this archive have been mostly based on information from taxa ...

Environmental Controls of Size Distribution of Modern Planktonic Foraminifera in the Tropical Indian Ocean

Geochemistry, Geophysics, Geosystems, 2023
Paleoceanographic studies often rely on abundance changes in microfossil species, with little consideration for characteristics such as organism size, which may also be related to environmental changes.
