Sustainable Arid Grassland Ecosystems studied the arctic grasslands and plants. Tundra insects have also developed adaptations for the cold; mosquitoes (Aedes nigripes), for example, have a chemical compound that acts as antifreeze, lowering the freezing temperature in their bodily fluids. Leaves are retained year-around, which enables the plant to photosynthesize even when the temperature drops sharply. With little sun, water evaporates slowly, making more available for plants or animals to use.

Tundra Plant Adaptations Tundra plants are small (usually less than 12 inches tall) and low-growing due to lack of nutrients, because being close to the ground helps keep the plants from freezing, and because the roots cannot penetrate the permafrost. Bearberry plants can reach between six and eight inches in height. Tundra organisms are opportunistic. The larger and taller they grow, the more they can influence soil temperatures and thaw the permafrost layer, or even change the soils nutrient cycle and carbon levels (affecting decomposition and the amount of CO2 released into the atmosphere). The tundra is a cold, harsh, dry ecosystem found in the Arctic, where it is known as Arctic tundra, and on mountain tops, where it is alpine tundra.
