Changes in foraminiferal assemblage size can be driven by changes in species diversity and by changes in size of the dominant species. Many species of planktonic foraminifera also contain single-celled organisms that create their own energy through photosynthesis (Fig. Planktic foraminifers are marine protozoans with calcareous Shells and chambered tests. Examples from the geological past may provide insight into how ecosystems respond to major shifts in environment. In regions of the deep ocean far from land the bottom is often made up almost entirely of the shells of planktonic species. Geochemical studies combined with culture experiments using planktic foraminifera provide much useful information about future biological and climatic responses on Earth. Studies of planktic foraminifera development to date have used a variety of tools, the easiest and most accessible being light microscopy and scanning electron microscopy (SEM) (Brummer et al., 1987).
