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

Sci Rep, 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.

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

Nat Commun, 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 ...

Planktonic foraminifera regulate calcification according to ocean density. [PDF]

Commun Earth Environ
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]

Sci 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]

PLoS 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

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.

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.
