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 ...

Planktonic foraminifera assemblage from Caribbean sediments that provide an accurate picture of the species community before human influence. Each shell is less than one millimeter in size. Michal ...

Calcified shells of planktonic foraminifera from Caribbean sediments. The individual shells are less than a millimeter in size and can only be identified properly under a microscope. The marine ...

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 ...

Foraminifera, an ancient and ecologically highly successful group of marine organisms, are found on and below the seafloor. Geobiologists report that several species not only survive, but thrive, in ...

Plankton don't get nearly the respect they deserve. These tiny organisms (phytoplankton being plant-like cells that produce much of the world’s oxygen, zooplankton being little animals) float around ...

Tiny single-celled organisms, many of them previously unknown, have been discovered beneath nearly seven miles of water (11 kilometers) in the deepest part of the ocean. A sample of sediment collected ...

University of Delaware student Erin Leathrum spent her summer looking for coiling party hats atop cinnamon buns at the bottom of the ocean. Not literal party hats and cinnamon buns, mind you, but ...

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 ...
