Because of the prevailing low temperatures, low humidities, frequent freeze-thaw cycles, and salinity of the soil, the Arid Cryosols of the Transantarctic Mountains are generally unfavorable environments for plant and animal life. Nevertheless, careful examination of the soil shows that habitable niches do exist, and organisms have colonized the soil and radiated to fill most of them. Food chains have formed, and a relatively large number of organisms occur in a relatively simple ecosystem.
