Large standing stocks of benthic foraminifera occur in the intense and shallow oxygen minimum of each of three areas in the eastern Pacific. These populations are characterized by high dominance, low diversity, and relatively small, thin-shelled specimens. Most of the calcareous tests produced are preserved in the anaerobic sediments associated with the oxygen minima because of apparent carbonate saturation of interstitial water. Oxygen is not a limiting ecological factor for benthic foraminifera in these low-oxygen environments.
