Sexual Reproduction of the Foraminiferan Planoglabratella opercularis (d'Orbigny, 1839) in Nature

Sexual Reproduction of the Foraminiferan Planoglabratella opercularis (d'Orbigny, 1839) in Nature The taxonomic composition of the entire foraminiferan assemblage in the southern part of Peter the Great Bay (Sea of Japan) was studied during the summer 1999 expedition. Along with other foraminiferans, several offspring-filled tests of Planoglabratella opercularis (d'Orbigny, 1839) were found in surface sediment samples. Based on the extensive literature on the reproductive cycle of foraminiferans and indirect evidence, it was found that each of the parent individuals of this species was a partner in a plastogamous pair, thus being a gamont, while their offspring were agamonts. The gamogony stage, contrary to the generally accepted opinion, took place under natural conditions in summer (not in fall or winter) at a bottom water temperature of 15–18°C. The results of this research may be important in paleogeographical and paleoecological reconstructions. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Russian Journal of Marine Biology Springer Journals
