RT Journal Article SR Electronic T1 Species Diversity: Benthonic Foraminifera in Western North Atlantic JF Science JO Science FD American Association for the Advancement of Science SP 72 OP 75 DO 10.1126/science.163.3862.72 VO 163 IS 3862 A1 Buzas, Martin A. A1 Gibson, Thomas G. YR 1969 UL http://science.sciencemag.org/content/163/3862/72.abstract AB Maximum species diversity occurs at abyssal depths of greater than 2500 meters. Other diversity peaks occur at depths of 35 to 45 meters and 100 to 200 meters. The peak at 35 to 45 meters is due to species equitability, whereas the other two peaks correspond to an increase in the number of species.
