Benthic foraminifera Bolivina argentea reproduced by dividing their cells when oxygen in the bottom water of Santa Barbara Basin was low and became very abundant. There were fewer B. argentea when bottom water oxygen was high, and a higher number of the specimens were the offspring of sexual reproduction. When the environment suited B. argentea during the coldest time period of the Little Ice Age, they reproduced very quickly through assexual cell division.
