Bronze Age herder burials have been found in the Gobi desert, as well as Karasuk bronze knives, and Mongolian deer stones. [21] Between 5000 cal BP and 4500 cal BP there was a period of desertification. [21] [22] Due to the increasing aridity between 3500 cal BP and 3000 cal BP there was a decline in human habitation in the Gobi desert.
The Gobi Lakes Valley is about 500 km (310 mi) west-to-east, and 150 km (93 mi) north-to south, at elevations of 1,000–1,400 metres (3,300–4,600 ft). [2] The region is desert steppe, with rivers from the Khangai Mountains on the north providing most of the water to the lakes. On the south the region is bounded by the Gobi-Altai range, the ...
The Alashan Plateau semi-desert ecoregion (WWF ID: PA1302) covers the southwestern portion of the Gobi Desert where precipitation in the mountains is sufficient for a short part of the summer to support sparse plant life. The terrain is basin and range, with elevations from 1,000 to 2,500 metres (3,300 to 8,200 ft).
The Mongolian-Manchurian grassland (Chinese: 蒙古高原草原-内蒙古草原-东北草原) covers an area of 887,300 square kilometers (342,600 sq mi).This temperate grasslands, savannas, and shrublands ecoregion of the Palearctic realm forms a large crescent around the Gobi Desert, extending across central and eastern Mongolia into the eastern portion of Inner Mongolia and eastern and ...
The Eastern Gobi desert steppe is a deserts and xeric shrublands ecoregion in Mongolia and northern China. It is the easternmost of the ecoregions that make up the larger Gobi Desert . It lies between the more humid Mongolian–Manchurian grassland on the north, east, and southeast, and the drier Alashan Plateau semi-desert to the west.
This page features a list of biogeographic provinces that were developed by Miklos Udvardy in 1975, [1] [2] later modified by other authors. [according to whom?] Biogeographic Province is a biotic subdivision of biogeographic realms subdivided into ecoregions, which are classified based on their biomes or habitat types and, on this page, correspond to the floristic kingdoms of botany.
Ecoregions of North America, featuring the 50 United States, the District of Columbia and the five inhabited territories. The following is a list of ecoregions in the United States as identified by the World Wide Fund for Nature (WWF). The United States is a megadiverse country with a high level of endemism across a wide variety of ecosystems.
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 Desert, become quite cold during the winter. [1] Temperature extremes are a characteristic of most deserts.
