Abstract: Low temperature and drought are the main environmental factors threatening the animals living in arctic area and cold temperate regions.To adapt the severe environment,the animals should adopt appropriate strategies.As a group of arthopods with freeze-avoiding strategy,soil springtails have the similar ecological mechanisms and modes of cold resistance/tolerance as insects,manifesting in the cold acclimation and drought tolerance to decrease the damage of ice crystal formation.During cold acclimation,there are a rapid increase of glycerol,a rapid decrease of fucose and glucose,and the production of anti-freeze proteins（AFP）,and exists the inter-transformation of different kinds of lipids to improve the flow of cell membrane to protect the cell from low temperature injury.In addition,soil springtails have their own specific modes and mechanisms to tolerate low temperature stress,mainly the vertical migration under the protection of snow cover and the excretion of ice nucleator from haemolymph,illustrating that it’s of significance to research the cryobiology of soil springtails.This paper summarized the modes and mechanisms of soil springtails in tolerating low temperature environment,reviewed the research progress on the eco-physiology of the springtails,discussed the existing problems of the researches on the low temperature tolerance of the springtails,and prospected the research directions of the springtails low temperature ecology under the background of global change.
