Plants of Saxifraga oppositifolia (Saxifragaceae) possess metabolic adaptations that allow them to grow successfully in polar desert microenvironments. Coniferous forests were present on Ellesmere Island and in northern Greenland, the northernmost land areas, in the mid-Pliocene (3.6 million years ago). They receive very little precipitation, the main forms of which are snow and fog. Corrections? This causes flooding before the water is lost into the sandy soil. Types of Desert Animals The armadillo lizard is an animal that is preyed upon on bigger and stronger predators.
