The desert biomes of the world are located in six biogeographic domains including: The Australian deserts consist of a collection of lowlands arid eco-regions in the heartland of Australia. The funnel-like leaves direct the rain water to the base of the tree, where it’s soaked up by shallow roots. The temperature also varies greatly depending on the location of the desert. Precipitation in hot and dry deserts is a lot different from precipitation in cold deserts. Figure 2. The very little rainfall experienced in desert biomes, as well as extreme daily temperature fluctuations, makes life difficult for plants. Every desert is different when it comes to precipitation. Temperatures exhibit daily extremes because the atmosphere contains little humidity to block the Sun's rays. Some plants, such as cacti, store water in their stems and use it very slowly, while others like bushes conserve water by growing few leaves or by having large root systems to gather water or few leaves. The chaparral biome is located in the Mediterranean climate zone, which means it experiences mild winter, as well as hot, dry summers, but not rainy. Annuals are referred to as ephemerals because some can complete an entire life cycle in weeks. In some years, some deserts may experience no rainfall at all. Desert Biome. In fact, the most important characteristic of a desert is that it receives very little rainfall. The Indo-Malay region consists of 2 hot lowlands including the Indus Valley and the Thar. Another adaptation of the cactus is that it grows slowly to save energy. Droughts are prevalent here. Deserts that receive rain as their main form of precipitation are referred to as 'hot' deserts, while deserts that receive snow as their main form of precipitation are 'cold' deserts. In some deserts such as Arica in Chile, the average annual rainfall is about 1 mm. In cold deserts the main source of precipitation is not rain as in the other types of deserts.

Some desert plant species have a short life cycle of a few weeks that lasts only during periods of rain. For example, a recognizable desert animal like the Camel can get by for days without food and water due to the fat stored in its hump. Organisms that make their home in the desert have specific adaptations to deal with the harsh environmental conditions. © 2020 . Animals in desert biomes have also developed adaptations such as panting to minimize heat, seasonal migration, and long periods of dormancy that lasts until triggered by moisture and temperature conditions. As well, the yearly evaporation is greater than the amount of rain that falls. Hot and Dry Deserts usually have very little rainfall and/or concentrated rainfall in short periods between long rainless periods.
