Diversity of Planktonic Foraminifera in Deep-Sea Sediments ... Jun 12, 1970 · The diversity of a planktonic foraminiferal assemblage on the ocean floor depends on the state of preservation of that assemblage. As dissolution progresses, species diversity (number of species in the assemblage) decreases, but compound diversity (based on relative species abundance) first increases and then decreases; species dominance first decreases and then increases. The reason for … Foraminifera, Foraminifera Gallery - illustrated catalog ... The Foraminifera.eu Newsletter 2020 is out.
