对日本西部新治中央湖沉积物柱样中的底栖有孔虫化石进行了研究，以作为新治湖-中见湖系统世纪古环境变化的指示物。世纪中期，从Haplophragmoides canariensis的优势地位过渡到Beccarii forma 1的优势地位。这种动物群的协会和它的过渡是类似的，在以前的研究中观察到的新寺湖和大桥河。这种动物群的转变可能不仅受到环境变化的影响，在新寺湖，但在大桥河。
Fossil benthic foraminifera from a sediment core taken from central Lake Shinji, western Japan, were investigated as an indicator of paleoenvironmental change in the Shinjiko-Nakaumi lake system during the 20th century. A transition from dominance of Haplophragmoides canariensis to that of Ammonia beccarii forma 1 occurred in the middle 20th century. This faunal association and its transition are similar to those observed in previous studies of Lake Shinji and the Ohashi River. This faunal transition might be affected by not only environmental change in Lake Shinji but also that in the Ohashi River.
