Denitrification by benthic foraminifera and their contribution to N-loss from a fjord environment [PDF]

open access: yesBiogeosciences, 2021
Oxygen and nitrate availabilities impact the marine nitrogen cycle at a range of spatial and temporal scales. Here, we demonstrate the impact of denitrifying foraminifera on the nitrogen cycle at two oxygen and nitrate contrasting stations in a fjord ...

Eocene foraminiferal biofacies in Kutch Basin (India) in context of palaeoclimate and palaeoecology

open access: yesJournal of Palaeogeography, 2019
The Eocene Epoch passed through multiple hyperthermal events and recorded highest temperatures in the Cenozoic. Very few studies from Eocene palaeotropical sites have recorded changes in shallow marine foraminiferal assemblages.

Technical Note: Determination of the metabolically active fraction of benthic foraminifera by means of Fluorescent In Situ Hybridization (FISH) [PDF]

open access: yes, 2011
Benthic foraminifera are an important component of the marine biota, but protocols for investigating their viability and metabolism are still extremely limited.

Long-term functional kleptoplasty in benthic foraminifera. [PDF]

open access: yesiScience
Foraminifera are highly diverse rhizarian protists, with some lineages having developed the ability to retain chloroplasts from algal prey (kleptoplasty). Recently, we revealed the evolutionary relationship between kleptoplasty and algal symbiosis in the benthic foraminifera Hauerina diversa.

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 ...

Identification of living (Rose Bengal)-stained benthic foraminifera using automated image recognition [PDF]

open access: yesJournal of Micropalaeontology
Living and fossil benthic foraminifera are widely used as bioindicators of ecosystem quality, but their analysis is time-consuming. With the help of artificial intelligence, models for the automatic identification of fossil planktonic foraminifera and ...

Benthic Foraminifera as Pollution Biomarkers: a Morphological Approach

open access: yesMicrobial Ecology, 2023
Abstract Coastal areas are often intervened by anthropic activities, which increase the contamination of toxic agents such as heavy metals. This causes adverse morphological effects on benthic microorganisms, such as foraminifera. This group is one of the most susceptible to environmental deterioration, so they can be used as pollution ...

Biofacies Analysis of the Upper Oligocene Deposits (Qom Formation) in Urumieh Dokhtar Zone, Iran [PDF]

open access: yesAnuário do Instituto de Geociências, 2017
In order to determine the accurate paleoenvironmental conditions of Qom Formation, one stratigraphic section was studied in the Urumieh-Dokhtar Zone (West of Ashtian).

Unique Habitat for Benthic Foraminifera in Subtidal Blue Holes on Carbonate Platforms

open access: yesFrontiers in Ecology and Evolution, 2021
Dissolution of carbonate platforms, like The Bahamas, throughout Quaternary sea-level oscillations have created mature karst landscapes that can include sinkholes and off-shore blue holes.
