Savanna
A savanna or savannah is a mixed woodland-grassland (i.e. grassy woodland) ecosystem characterised by the trees being sufficiently widely spaced so that the canopy does not close. The open canopy allows sufficient light to reach the ground to support an unbroken herbaceous layer consisting primarily of grasses. According to '' Britannica'', there exists four savanna forms; ''savanna woodland'' where trees and shrubs form a light canopy, ''tree savanna'' with scattered trees and shrubs, ''shrub savanna'' with distributed shrubs, and ''grass savanna'' where trees and shrubs are mostly nonexistent.Smith, Jeremy M.B.. "savanna". Encyclopedia Britannica, 5 Sep. 2016, https://www.britannica.com/science/savanna/Environment. Accessed 17 September 2022. Savannas maintain an open canopy despite a high tree density. It is often believed that savannas feature widely spaced, scattered trees. However, in many savannas, tree densities are higher and trees are more regularly spaced than in for ...

Mulga (habitat)
Mulga is a type of habitat composed of woodland or open forest dominated by the mulga tree, '' Acacia aneura'', or similar species of '' Acacia''. Regions It is found across Australia, covering 20% of arid regions, including much of southwestern Queensland, New South Wales, South Australia, and Western Australia. The Mulga Lands are an interim Australian bioregion located in northwestern New South Wales and southwestern Queensland in eastern Australia consisting of dry sandy plains with low mulga woodlands and shrublands that are dominated by mulga. The Western Australian mulga shrublands is a large dry World Wildlife Fund ecoregion of inland Western Australia. Vegetation The vegetation type is associated with the extensive plains of the continent's interior and other arid regions with infrequent and irregular rainfall. Mulga country intersperses with other vegetation such as spinifex, dominated by low mounds of '' Triodia'', and wattle scrub (Mimosaceae) or interrupted by gra ...

Northwestern Thorn Scrub Forests
The Northwestern thorn scrub forests, presently known as Aravalli west thorn scrub forests, is a xeric shrubland ecoregion of Pakistan and Northern India, stretching along the border lowlands and hills between the two countries. Once covered in deciduous forest, this ecoregion has been degraded through agriculture and the extraction of timber so that it currently has a scanty covering of thorny scrub dominated by such trees as ''Acacia senegal'', ''Acacia leucophloea'' and ''Prosopis cineraria''. Where the soils are particularly saline, there are patches of semi-desert. A number of mammals are found in this habitat, including about four hundred species of bird. Some small areas are protected but the collection of firewood and the conversion of the land to subsistence farming continues. Location and description The ecoregion encircles the Thar Desert and Indus Valley Desert ecoregions. It stretches along the border lowlands and hills between India and Pakistan and includes: th ...

Deserts And Xeric Shrublands
Deserts and xeric shrublands are a biome defined by the World Wide Fund for Nature. Deserts and xeric (ancient Greek 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 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, become quite cold in 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.

Biogeographic Realm
A biogeographic realm or ecozone is the broadest biogeographic division of Earth's land surface, based on distributional patterns of terrestrial organisms. They are subdivided into bioregions, which are further subdivided into ecoregions. Description The realms delineate large areas of Earth's surface within which organisms have evolved in relative isolation over long periods of time, separated geographic features, such as oceans, broad deserts, or high mountain ranges, that constitute natural barriers to migration. As such, biogeographic realm designations are used to indicate general groupings of organisms based on their shared biogeography. Biogeographic realms correspond to the floristic kingdoms of botany or zoogeographic regions of zoology. From 1872, Alfred Russel Wallace developed a system of zoogeographic regions, extending the ornithologist Philip Sclater's system of six regions. Biogeographic realms are characterized by the evolutionary history of the orga ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Indomalayan
The Indomalayan realm is one of the eight biogeographic realms. It extends across most of South and Southeast Asia and into the southern parts of East Asia. Also called the Oriental realm by biogeographers, Indomalaya spreads all over the Indian subcontinent and Southeast Asia to lowland southern China, and through Indonesia as far as Sumatra, Java, Bali, and Borneo, east of which lies the Wallace line, the realm boundary named after Alfred Russel Wallace which separates Indomalaya from Australasia. Indomalaya also includes the Philippines, lowland Taiwan, and Japan's Ryukyu Islands. Most of Indomalaya was originally covered by forest, and includes tropical and subtropical moist broadleaf forests, with tropical and subtropical dry broadleaf forests predominant in much of India and parts of Southeast Asia. The tropical forests of Indomalaya are highly variable and diverse, with economically important trees, especially in the families Dipterocarpaceae and Fabaceae. Major ecolog ...
