Foraminifera are single-celled marine protozoa that construct and inhabit a calcium carbonate shell composed of several chambers. These chambers are usually penetrated by pores through which the ...

Limnology and Oceanography, Vol. 57, No. 4 (2012), pp. 1011-1024 (14 pages) We investigated the controls on the δ15N values of shell-bound organic matter of planktonic foraminifera (foraminifera-bound ...

Impact of single-cell organisms on sediment oxygen levels and bacterial diversity measured for the first time. Dr. Dewi Langlet, a scientist at the Evolution, Cell Biology and Symbiosis Unit at the ...

Planktonic foraminifera are microorganisms that live in the uppermost water layers of all oceans. When they die, their small calcareous shells sink to the bottom of the ocean and remain there in the ...

Through their burrowing actions, foraminifera increase oxygen flow into marine sediments, causing a decrease in organic matter and bacterial richness. This, in turn, decreases the movement of oxygen ...
