[6] [7] Desert chaparral is a regional ecosystem subset of the deserts and xeric shrublands biome, with some plant species from the California chaparral and woodlands ecoregion. Unlike cismontane chaparral, which forms dense, impenetrable stands of plants, desert chaparral is often open, with only about 50% of the ground covered. [8]
Biome-type: grouping of convergent biomes or formations of different continents, defined by physiognomy. Formation-type: a grouping of convergent formations. Whittaker's distinction between biome and formation can be simplified: formation is used when applied to plant communities only, while biome is used when concerned with both plants and ...
The Nama Karoo of Namibia has the world's richest desert fauna. [8] The Chihuahuan desert and Central Mexican matorral are the richest deserts in the Neotropics. [9] The Carnarvon xeric shrublands of Australia are a regional center for endemism. [1] The Sonoran and Baja deserts of Mexico are unusual desert communities dominated by giant ...
Creosote bush scrub is a North American desert vegetation type (or biome) of sparsely but evenly spaced desert plants dominated by creosote bush (Larrea tridentata) and its associates. Its visual characterization is of widely spaced shrubs that are somewhat evenly distributed over flat or relatively flat desert areas that receive between 2 and ...
The desert contains a variety of unique endemic plants and animals, notably, the saguaro (Carnegiea gigantea) and organ pipe cactus (Stenocereus thurberi). The Sonoran Desert is clearly distinct from nearby deserts (e.g., the Great Basin , Mojave , and Chihuahuan deserts ) because it provides subtropical warmth in winter and two seasons of ...
Sand dunes in the Sahara Desert. Desert ecology is the study of interactions between both biotic and abiotic components of desert environments. A desert ecosystem is defined by interactions between organisms, the climate in which they live, and any other non-living influences on the habitat.
Desert birds and lizards are predators of C. pallida, and these bees can be parasitized by the meloid beetle (Tegrodera erosa); however, rain is the largest threat to these bees. [12] At night and during the heat of the day, C. pallida bees will hide under rocks, trees, in burrows, etc.
