We have obtained the first data demonstrating the capability of multicellular organisms for longterm cryobiosis in permafrost deposits of the Arctic. The viable soil nematodes Panagrolaimus aff. detritophagus (Rhabditida) and Plectus aff. parvus (Plectida) were isolated from the samples of Pleistocene permafrost deposits of the Kolyma River Lowland. The duration of natural cryopreservation of the nematodes corresponds to the age of the deposits, 30 000-40 000 years.
我们获得了首批数据，证明多细胞生物具有在北极永久冻土沉积物中进行长期低温保存的能力。从科雷马河低地更新世永久冻土沉积物样本中分离出了存活的土壤线虫——近似食腐类小杆线虫（小杆目）和近似微小盘咽线虫（盘咽目）。线虫自然冷冻保存的持续时间与沉积物的年龄相符，为3万至4万年。
