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

open access: yesBiogeosciences, 2018
. 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 Osmium Isotope Signature of Phanerozoic Large Igneous Provinces

open access: yesGeophysical Monograph Series, Page 229-246., 2021

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

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

Chamber-by-Chamber Measurements of Planktonic Foraminiferal Mg, Sr, and Na to Ca Ratios With Femtosecond LA-ICP-MS. [PDF]

open access: yesRapid Commun Mass Spectrom
ABSTRACT Rationale Distribution patterns of foraminifera are controlled by environmental parameters such as temperature, salinity, and nutrient concentrations in each water mass. Since trace elements to Ca ratios of marine microfossil calcite test of foraminifera record environmental and ecological habitat information, we used femtosecond (fs) LA‐ICP ...

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 ...

Denitrification in foraminifera has an ancient origin and is complemented by associated bacteria

open access: yesbioRxiv, 2021
Benthic foraminifera are unicellular eukaryotes that inhabit sediments of aquatic environments. Several foraminifera of the order Rotaliida are known to store and use nitrate for denitrification, a unique energy metabolism among eukaryotes.

Impact of carbonate saturation on large Caribbean benthic foraminifera assemblages [PDF]

open access: yesBiogeosciences, 2018
Increasing atmospheric carbon dioxide and its dissolution in seawater have reduced ocean pH and carbonate ion concentrations, with potential implications on calcifying organisms.

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

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