چکیده انگلیسی
The survival of ciliate resting cysts, in the presence and absence of soil, was studied under two environmental stresses: desiccation and freezing. Laboratory strains of the common species Colpoda inflata and the rare species Meseres corlissi were used in these experiments, which yielded the following results: 1) Freezing of cysts in soil with a residual moisture level exceeding ∼30% was destructive for both species. 2) Survival of Meseres corlissi cysts depended largely on the presence of soil. 3) In the absence of soil, Colpoda inflata cysts had greater tolerance to desiccation and freezing than Meseres corlissi cysts. Possible consequences for the distribution of natural populations are discussed.
