⭐ Core Definition: Deserts and xeric shrublands

Deserts and xeric shrublands are a biome defined by the World Wide Fund for Nature. Deserts and xeric (Ancient Greek ξηρός xērós 'dry') shrublands form the largest terrestrial biome, covering 19% of Earth's land surface area. Ecoregions in this habitat type vary greatly in the amount of annual rainfall they receive, usually less than 250 millimetres (10 in) annually except in the margins. Generally evaporation exceeds rainfall in these ecoregions. Temperature variability is also diverse in these lands. Many deserts, such as the Sahara, are hot year-round, but others, such as East Asia's Gobi Desert, become quite cold during the winter.

Temperature extremes are a characteristic of most deserts. High daytime temperatures give way to cold nights because there is no insulation provided by humidity and cloud cover. The diversity of climatic conditions, though quite harsh, supports a rich array of habitats. Many of these habitats are ephemeral in nature, reflecting the paucity and seasonality of available water. Woody-stemmed shrubs and plants characterize vegetation in these regions. Above all, these plants have evolved to minimize water loss. Animal biodiversity is equally well adapted and quite diverse.

👉 Deserts and xeric shrublands in the context of Mesic habitat

In ecology, a mesic habitat is a type of habitat with a well-balanced or moderate supply of moisture throughout the growing season (e.g., a mesic forest, temperate hardwood forest, or dry-mesic prairie). The term derives from the Greek mesos, meaning middle, indicating its relative moisture content between hydric (moist) and xeric (dry) habitats. The word "mesic" can apply to the plants or soils within the mesic habitat (i.e. mesic plants, mesic soils).

Mesic habitats provide a moderate moisture content that remains relatively constant during crucial growing periods. A variety of outside factors contribute to the presence of water in the system, including streams and their offshoots, wet meadows, springs, seeps, irrigated fields, and high-elevation habitats. These factors effectively provide drought insurance during the growing season against climatic factors such as increasing temperatures, lack of rain, and the effects of urbanization.

Deserts and xeric shrublands in the context of Aruba

Aruba, officially the Country of Aruba, is a constituent island country within the Kingdom of the Netherlands, in the southern Caribbean Sea 29 kilometres (18 mi) north of the Venezuelan peninsula of Paraguaná and 80 kilometres (50 mi) northwest of Curaçao. In 1986, Aruba became a constituent country within the Kingdom of the Netherlands and acquired the formal name the Country of Aruba.

Aruba has an area of 179 km (69.1 sq mi). Aruba measures 32 kilometres (20 mi) in length from its northwestern to its southeastern end and is 10 kilometres (6 mi) across at its widest point. Aruba is geologically located in South America, lying on the South American continental shelf. Alongside Bonaire and Curaçao, Aruba forms part of an island group referred to as the ABC islands. The Dutch Caribbean encompasses the ABC islands along with the other three substantial islands, the SSS islands. In contrast to much of the Caribbean, which experiences humid tropical climates, Aruba has a dry climate with an arid xeric landscape. The relatively warm and sunny weather persists throughout the year.

Deserts and xeric shrublands in the context of Arabian Desert

The Arabian Desert (Arabic: ٱلصَّحْرَاء ٱلْعَرَبِيَّة) is a vast desert wilderness in West Asia that occupies almost the entire Arabian Peninsula with an area of 2,330,000 square kilometers (900,000 sq mi). It stretches from Yemen to the Persian Gulf and Oman to Jordan and Iraq. It is the fourth largest desert in the world and the largest in Asia. At its center is Ar-Rub' al-Khali (The Empty Quarter), one of the largest continuous bodies of sand in the world. It is an extension of the Sahara Desert.

Gazelles, oryx, sand cats, and spiny-tailed lizards are just some of the desert-adapted species that survive in this extreme environment, which features everything from red dunes to deadly quicksand. The climate is mostly dry (the major part receives around 100 mm (3.9 in) of rain per year, but some very rare places receive as little as 50 mm), and temperatures oscillate between very high heat and seasonal night time freezes. It is part of the deserts and xeric shrublands biome and lie in biogeographical realms of the Palearctic (northern part) and Afrotropical (southern part).

Deserts and xeric shrublands in the context of Nine-banded armadillo

The nine-banded armadillo (Dasypus novemcinctus), also called the nine-banded long-nosed armadillo or common long-nosed armadillo, is a species of armadillo native to North, Central, and South America, making it the most widespread of the armadillos.

Its ancestors originated in South America, and remained there until the formation of the Isthmus of Panama allowed them to enter North America as part of the Great American Interchange.The nine-banded armadillo is a solitary, mainly nocturnal animal, found in many kinds of habitats, from mature and secondary rainforests to grassland and dry scrub. It is an insectivore, feeding chiefly on ants, termites, and other small invertebrates. The armadillo can jump 91–120 cm (3–4 ft) straight in the air if sufficiently frightened, making it a particular danger on roads. It is the state small mammal of Texas.

Deserts and xeric shrublands in the context of List of North American deserts

This list of North American deserts identifies areas of the continent that receive less than 10 in (250 mm) annual precipitation. The "North American Desert" is also the term for a large U.S. Level 1 ecoregion (EPA) of the North American Cordillera, in the Deserts and xeric shrublands biome (WWF). The continent's deserts are largely between the Rocky Mountains and Sierra Madre Oriental on the east, and the rain shadow–creating Cascades, Sierra Nevada, Transverse, and Peninsular Ranges on the west. The North American xeric region of over 95,751 sq mi (247,990 km) includes three major deserts, numerous smaller deserts, and large non-desert arid regions in the Western United States and in northeastern, central, and northwestern Mexico.
