...Living foraminiferal population densitymay reach 100 specimens per 10 cm3 (size fraction >125 μm) in near-shore areas that are rather rich in food, but values may drop to tens of specimens and even less during winter at mid to high latitudes (e.g., Lehmann, 2000; Murray, 2006)....

...Although the 125 μm-fraction should be preferentially used to obtain census data of benthic foraminiferal assemblages in foraminiferal bio-monitoring as explained below, many ecological studies are based on assemblages >63 μm (Murray, 2006)....

...…(e.g., Alve, 1995a; Mojtahid et al., 2006; Bouchet et al., 2007; Alve et al., 2009; Jorissen et al., 2009): • Their density in marine sediments, between 100 and 10000 living individuals >63 μm per 100 cm2 surface area (Murray, 2006), is an order of magnitude higher than that of macrofauna....

...This procedure ensures that the preservative is not diluted too much by the pore water so that ethanol concentrations do not fall below 70% (Gustafsson and Nordberg, 1999; Murray, 2006)....

...Because benthic foraminifers inhabit a wide range of aquatic environments and can be found in densities of up to several million individuals per square meter (3), they may play an important role in temporal nitrate sequestering, nitrate transport, and nitrogen removal through denitrification....
