This is reflected in their use of animal hides and scavenged tree branches to make tepees, as well as their use of ice blocks to make igloos. Sharon Robinson (TEDxUWollongongWomen Talk: Antarctic plants in a time of change), a plant ecophysiologist at Australia’s University of Wollongong, studies the three species of moss — Schistidium antarctici, Bryum pseudotriquetrum and Ceratodon purpureus — that grow in East Antarctica, a particularly cold, windy and rocky area of the continent. Thinkquest says researchers have found some types of mushrooms on the peninsula’s west coast and South Shetland Islands. Nitrogen in the droppings sustain the moss, which grows at a rate of 2 to 3 millimeters a year and houses insects and other small creatures that live in the inhospitable climate. The estimated 50 species of mosses and liverworts, known as bryophytes, prefer sand- and gravel-based soils, according to Thinkquest.

Dr. David Dallmeyer, professor emeritus in the … They can endure lengthy high-stress periods in dormancy and almost instantly become photosynthetic when conditions improve. It doesn’t rain in continental Antarctica, so water is available only when snow and ice melt. Marine plants need light in order to photosynthesise and grow. Expanses of snow and layers of ice, some nearly 3 miles thick, cover 98 percent of Antarctica. Pearlwort produces small white, tubular flowers on a long green stalk, while hair grass produces tufts of fine, light green leaves and delicate flowers. When young they have folded leaf blades then develop into long, dark green, erect stems. Lichens, although slow-growing, are particularly well adapted to Antarctic survival. Some mosses and lichens however can be found even in the dry interior. There is not any claim life in Antarctica during the winter months. The discovery was part of a study conducted by scientists from the University of Wollongong in Australia to learn about how plants survive in icy regions where the soil is scarce in nutrients.
