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

Smaller benthic foraminifera Analysis of Kudat Formation, Kudat, Sabah: Preliminary Interpretation. [PDF]
Geological 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 ...

Benthic Foraminifera as Pollution Biomarkers: a Morphological Approach
Microbial 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 ...

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

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.
