These organisms have a dramatically higher abundance and greater species diversity in polar and sub-polar environments than is seen in temperate and tropical waters. Based on our finding of abundant and well-preserved walls of these organisms in Antarctic sediments, we suggest that they represent a useful biofacies and paleoenvironmental marker for deposition from cold water, and a potentially new biostratigraphic tool. 关键词: SCHISTOSOMIASIS; VACCINE; T LYMPHOCYTE IGE; NANOPLANKTON; COCCOLITHOPHORIDS; PACIFIC; CYSTS
