The role of benthic foraminifera in the benthic nitrogen cycle of the Peruvian oxygen minimum zone [PDF]

Biogeosciences, 2013
The discovery that foraminifera are able to use nitrate instead of oxygen as an electron acceptor for respiration has challenged our understanding of nitrogen cycling in the ocean.

Multiple Ecological Parameters Affect Living Benthic Foraminifera in the River-Influenced West-Central Bay of Bengal

Frontiers in Marine Science, 2021
The huge riverine influx and associated processes decrease the ambient salinity, stratify the water column, modulate the oxygen-deficient zone, and are also responsible for the recent acidification in the Bay of Bengal.

Benthic Foraminifera of the Upper Jurassic Platform Carbonate Sequence in the Aydincik (Içel) Area, Central Taurides, S Turkey

Geologia Croatica, 2001
The Upper Jurassic sequence of the Aydincik (Içel) area consists of platform limestones which were deposited in a subtidal, restricted lagoon environment. Stratigraphic distribution of benthic foraminifera and calcareous algae, examined in thin-sections,

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

Nature 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 ...

The life and research interests of John W. Murray [PDF]

Journal of Micropalaeontology
John W. Murray (1936–2021) was a pioneering micropalaeontologist and became a globally celebrated foraminiferal ecologist and an authority on the smaller benthic foraminifera of the UK and neighbouring areas.

Biostratigraphy and paleoenvironment of Maastrichtian foraminiferal assemblages from a succession located NW of Tuxtla Gutiérrez, Chiapas (SE Mexico)

Revista Mexicana de Ciencias Geológicas, 2021
During the Maastrichtian, two lithostratigraphic units were deposited in the central Chiapas region; the Ocozocoautla and Angostura formations. The first unit crops out northwest of the city of Tuxtla Gutiérrez in central Chiapas.

Late Miocene to Early Pliocene benthic foraminifera from the Tasman Sea (Integrated Ocean Drilling Program Site U1506) [PDF]

Journal of Micropalaeontology
Modern and fossil benthic foraminifera have been widely documented from New Zealand, but detailed studies of material collected from drilling expeditions in the Tasman Sea are scarcer.

Exploring the controls on element ratios in middle Eocene samples of the benthic foraminifera Oridorsalis umbonatus [PDF]

Culturing studies and empirically based core top calibrations have been used to infer that elemental ratios in benthic foraminifera can be used as proxies to reconstruct past variations in bottom water temperature and saturation state (Δ [CO32 ...

Compound‐specific isotope analysis of benthic foraminifer amino acids suggests microhabitat variability in rocky‐shore environments

Ecology and Evolution, 2018
The abundance and biomass of benthic foraminifera are high in intertidal rocky‐shore habitats. However, the availability of food to support their high biomass has been poorly studied in these habitats compared to those at seafloor covered by sediments ...

Automated identification of fossil benthic foraminifera from the Peruvian margin using convolutional neural networks [PDF]

Journal of Micropalaeontology
Benthic foraminifera tests preserved in marine sediments are well-established proxies for bottom-water dynamics, yet their minute size and high diversity demand laborious manual identification of hundreds of individuals to reconstruct subtle faunal ...
