0 a large area of land with grass but no trees, especially in eastern Europe, Russia, and Central Asia -- （尤指东南欧、俄罗斯和亚洲北部无树的）干草原，大草原
Middendorff disproved such a view: while steppes came into being due to dryness, tundra came into existence because of the lack of warmth.
The first of the belts is the transitional forested steppe.
In about half of the villages, some cereal stubble was rented out to other farmers or migrant herders (bedouin nomads from the steppe).
Our results indicate that most species of such grassdominated steppes could also be used directly without any dormancy-breaking treatment.
In the latenineteenth century, moreover, all four steppe regions were losing population through net emigration.
This is sited in areas adjacent to the dry steppe with an annual rainfall of between 200 and 350 mm.
But we can gauge the slow loss of comprehension of some steppe traditions if we recall the example of the ulagh/ulaq.
The most favourable habitat appears to be the moist forested steppe, and transmission gradually decreases in dry steppe, semi-desert and desert areas.
