A desert is a landscape where little precipitation occurs and, consequently, living conditions create unique biomes and ecosystems. The lack of vegetation exposes the unprotected surface of the ground to denudation .
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 ...

Erg – Broad area of desert covered with wind-swept sand; Etchplain – Plain where the bedrock has been subject to considerable subsurface weathering; Exhumed river channel – Ridge of sandstone that remains when the softer flood plain mudstone is eroded away; Fjord – Long, narrow inlet with steep sides or cliffs, created by glacial activity
Also Gause's law. A biological rule which states that two species cannot coexist in the same environment if they are competing for exactly the same resource, often memorably summarized as "complete competitors cannot coexist". coniferous forest One of the primary terrestrial biomes, culminating in the taiga. conservation biology The study of Earth's biodiversity with the aim of protecting and ...
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. Deserts are arid regions that are generally associated with warm temperatures; however ...
Also called desert grasslands, they are composed of sparse grassland ecoregions located in the deserts and xeric shrublands biome. Temperature extremes and low amounts of rainfall characterise these kinds of grasslands. Therefore, plants and animals are well adapted to minimize water loss. [62]
Tundra tends to be windy, with winds often blowing upwards of 50–100 km/h (30–60 mph). However, it is desert-like, with only about 150–250 mm (6–10 in) of precipitation falling per year (the summer is typically the season of maximum precipitation). Although precipitation is light, evaporation is also relatively minimal.
