They heat rapidly and cool rapidly at night. Plants have many adaptations for conserving water or storing it. Animals are mostly nocturnal. Tough woody plants that conserve water. Not very productive.
Animals browse leaves.
Good goat country. Usually kept grassy by prolonged droughts that kill trees. Continuos canopy preserves humidity at ground level Deer, browsers and grazers, squirrels, wide variety of animals Coniferous Forests Shallow soils or poorly nutritive Deer, porcupines, squirrels Tundra Low rainfall, but wet as there is little evaporation Subsoil may remain frozen Snow covered in winter - short growing season Freshwater Lakes Temperate lakes produce a thermocline in the summer as the surface waters heat up. Cold water at 4 degrees centigrade is the most dense and collects in the bottom. The thermocline prevents mixing deeper and surface waters.
