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

open access: yesNature 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 ...

Macroevolutionary patterns in intragenomic rDNA variability among planktonic foraminifera [PDF]

open access: yesPeerJ, 2023
Ribosomal intragenomic variability in prokaryotes and eukaryotes is a genomic feature commonly studied for its inflationary impact on molecular diversity assessments.

Planktonic foraminifera eDNA signature deposited on the seafloor remains preserved after burial in marine sediments [PDF]

open access: yesScientific Reports, 2020
Environmental DNA (eDNA) metabarcoding of marine sediments has revealed large amounts of sequences assigned to planktonic taxa. How this planktonic eDNA is delivered on the seafloor and preserved in the sediment is not well understood.

Planktonic foraminifera regulate calcification according to ocean density [PDF]

open access: yesCommunications Earth & Environment
Planktonic foraminifera are key contributors to the oceanic carbon cycle. In pelagic environments, carbonate production by planktonic biomineralizers regulates ocean-atmosphere carbon dioxide exchange and exports surface carbon to the deep ocean. Here we

The FORCIS database: A global census of planktonic Foraminifera from ocean waters [PDF]

open access: yesScientific Data, 2023
Planktonic Foraminifera are unique paleo-environmental indicators through their excellent fossil record in ocean sediments. Their distribution and diversity are affected by different environmental factors including anthropogenically forced ocean and ...

Unassigned diversity of planktonic foraminifera from environmental sequencing revealed as known but neglected species. [PDF]

open access: yesPLoS ONE, 2019
Most research on extant planktonic foraminifera has been directed towards larger species (>0.150 mm) which can be easily manipulated, counted and yield enough calcite for geochemical analyses. This has drawn attention towards the macroperforate clade and

Ecological partitioning and diversity in tropical planktonic foraminifera [PDF]

open access: yesBMC Evolutionary Biology, 2012
Background Ecological processes are increasingly being viewed as an important mode of diversification in the marine environment, where the high dispersal potential of pelagic organisms, and a lack of absolute barriers to gene flow may limit the ...

Taxonomic review of living planktonic foraminifera [PDF]

open access: yesJournal of Micropalaeontology, 2022
Applications of fossil shells of planktonic foraminifera to decipher past environmental change and plankton evolution require a robust operational taxonomy.

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

open access: yesJournal 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.
