Definition and characteristics of arid ecosystems from "summary" of Floristic Study of Arid Ecosystem: Ecology and Phytosociology by Dr. Ekta B. Joshi,Dr. Hiren B. Soni ,Dr. Pankaj N. Joshi
Arid ecosystems are characterized by low precipitation levels, high temperatures, and limited vegetation cover. These ecosystems are often found in regions with rainfall of less than 250 mm per year, making water availability a critical factor for the survival of plants and animals. The scarcity of water in arid ecosystems not only affects the flora and fauna but also impacts the overall ecosystem dynamics and functioning. One of the defining characteristics of arid ecosystems is the presence of xerophytic plants, which have adapted to survive in water-stressed environments. These plants often have specialized features such as deep root systems, succulent leaves, and waxy coatings to reduce water loss through transpiration. The vegetation in arid ecosystems is typically sparse and dominated by drought-resistant species that can withstand long periods of dryness. In addition to xeroph...
