Tropical heat generates unstable air in this area, and air masses become extremely dry due to the loss of moisture during the process of tropical ascent. [1] Hadley cell above Sahara desert. Another significant determinant of tropical desert climate are Hadley cells. Hadley cells concentrate all precipitations in the hotter humid lower pressure ...
extent of tropical and subtropical grasslands, savannas, and shrublands. Tropical and subtropical grasslands, savannas, and shrublands is a terrestrial biome defined by the World Wide Fund for Nature. [1] The biome is dominated by grass and/or shrubs located in semi-arid to semi-humid climate regions of subtropical and tropical latitudes ...
The Colorado Desert is the low area of the Colorado River Valley and surrounding hills and mountains. Plants must survive its hot and dry conditions. [2]: 7 Temperatures can be greater than 120 °F (49 °C). [2]: 7 Annual precipitation is sometimes less than 3 inches (7.6 cm).
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 ...
The fifth and final layer is the herb layer which is the forest floor. The forest floor is mainly bare except for various plants, mosses, Lycopods and ferns. The forest floor is much more dense than above because of little sunlight and air movement. [2] Plant species native to the tropics found in tropical ecosystems are
The South Saharan steppe and woodlands, also known as the South Sahara desert, is a deserts and xeric shrublands ecoregion of northern Africa. This band is a transitional region between the Sahara's very arid center (the Sahara desert ecoregion ) to the north, and the wetter Sahelian Acacia savanna ecoregion to the south. [ 1 ]
A unique feature of many tropical páramos is the presence of giant rosette plants from a variety of plant families, such as Lobelia (Africa), Puya (South America), Cyathea (New Guinea), and Argyroxiphium (Hawai’i). These plant forms can reach elevations of 4,500–4,600 metres (14,800–15,100 ft) above sea level. [1]
An example of a halophyte is the salt marsh grass Spartina alterniflora (smooth cordgrass). Relatively few plant species are halophytes—perhaps only 2% of all plant species. Information about many of the earth's halophytes can be found in the halophyte database.
