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. Tropical grasslands are mainly found between 5 degrees and 20 degrees in both ...
[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]
The flora of the alpine tundra is characterized by plants that grow close to the ground, including perennial grasses, sedges, forbs, cushion plants, mosses, and lichens. [28] The flora is adapted to the harsh conditions of the alpine environment, which include low temperatures, dryness, ultraviolet radiation, and a short growing season.
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.
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 leaves radiate from the center of the plant's apex in all directions (spherical). Blooming from May to July, the flowering stem grows above the foliage, to a height of 5 m (16 ft) tall [1] and a diameter of 3 cm (1 + 1 ⁄ 4 in). The stem is topped by a long plume of straw-colored small flowers about 2.5 cm long with six tepals. The color ...
Spiny plants of the endemic subfamily Didiereoideae form a conspicuous component, especially towards the east. They are woody but distantly related to the cacti. The remaining component of the forests is dominated by members of the plant families Burseraceae, Euphorbiaceae, Anacardiaceae and Fabaceae, all of which have representatives elsewhere ...
Montane grasslands and shrublands are a biome defined by the World Wildlife Fund. [1] The biome includes high elevation grasslands and shrublands around the world. The term "montane" in the name of the biome refers to "high elevation", rather than the ecological term that denotes the region below the treeline.
