TL;DR: It is demonstrated that the foraminifer Globobulimina pseudospinescens accumulates intracellular nitrate stores and that these can be respired to dinitrogen gas, indicating that the understanding of the complexity of the marine nitrogen cycle is far from complete.
Journal ArticleDOI

TL;DR: Benthic foraminifers inhabit a wide range of aquatic environments including open marine, brackish, and freshwater environments and Gromia, another taxon also belonging to Rhizaria, accumulate and respire nitrates through denitrification.
Journal ArticleDOI
Vertical migration, nitrate uptake and denitrification: survival mechanisms of foraminifers (Globobulimina turgida) under low oxygen conditions
TL;DR: In this paper, the role of pseudopodial networks in 15NO3− isotope labeling experiments was investigated, and it was found that foraminifera cannot extend their pseudopods for nitrate uptake through several millimetres of sediment, but must physically migrate upwards closer to nitrate-containing strata.
Vertical migration, nitrate uptake and denitrification: survival mechanisms of foraminifers (Globobulimina turgida) under low oxygen conditions
TL;DR: Investigation of foraminiferal nitrate uptake strategies and the role of pseudopodial networks showed that foraminifera actively collect nitrate both in the presence and in the absence of oxygen, although uptake was initiated faster if oxygen was absent from the environment.
Journal ArticleDOI
Survival and life strategy of the foraminiferan Globobulimina turgida through nitrate storage and denitrification
TL;DR: G. turgida can survive prolonged anoxia (3 mo) as long as nitrate is available to sustain its respiration, but it remains unsure whether growth or reproduction can take place under anoxic conditions.
