掘地鼹鼠（S. Ehrenbergi）可栖息在具有低透气性的重质土壤中。重土洞穴空气成分比轻土洞穴更偏离大气成分。在冬季和春季的O_2和CO_2浓度在繁殖土丘是16.5%O_2和2.5- 3%CO_2和极端值测量为14.0%O_2和4.8%CO_2。当下雨后和环境温度下降时，洞穴中的缺氧和高碳酸血症会很快发展。洞穴空气的组成是由土壤水中的溶解度的CO2和更快的渗透比流出的CO2的O2。
The fossorial mole rat (S. ehrenbergi) may inhabit heavy soil with low gas permeability. Air composition in burrows in heavy soil deviates from atmospheric air more than that of burrows in light soil. In winter and spring O2 and CO2 concentrations in breeding mounds were 16.5% O2 and 2.5-3% CO2 and the extreme values measured were 14.0% O2 and 4.8% CO2. Hypoxia and hypercapnia in the burrow develop shortly after rain and when ambient temperature drops. Composition of the burrows air is influenced by the solubility of CO2 in soil water and by faster penetration of O2 than outflowing of CO2.
