the mechanisms underlying those changes,we conducted a field experiment in the range of 2250-2300 m in the alpine tundra of the Changbai Mountain and collected a total of 288 samples from four degrees of herbac
Probably the most important environmental factor is temperature, for if the growing season is too short and temperatures are too low, tree shoots and buds cannot mature sufficiently to survive the winter months. Above the tree line there is a zone that is generally called alpine tundra. ...
Alpine biomes are regions found high in the mountains throughout the world, usually at altitudes of more than 10,000 feet. Alpine biomes are characterized by cold temperatures, abundant wind and relatively low rainfall. Conditions for life in these areas can be difficult....
The maze of fjords and islands, streams and mountains characterizing the Region support a wide array of vegetation types ranging from vast wetlands to luxuriant temperate rainforests to magnificent alpine ecosystems. There are about 1,700 types of plants in the Alaskan Tundra. What most of them ...
Generally categorized as Arctic or alpine, tundra refers to a treeless biome that ranks among the coldest on Earth. Though covered in snow most of the year, the tundra experiences a short summer growing season during which animal and plant activity peaks. Virtually no reptiles or amphibians can...
This needs to be considered in view of a total flora of the arctic tundra of about 1000 to 1500 species (depending on how sub-species are ranked). In this respect, biodiversity of the alpine life zone is outstanding. A distinct mountain region such as the Teton Range in Wyoming, the ...

However, in the present volumes, we have used the word tundra in a broader sense as approximating areas with mean annual air 0 temperature below 0 C at meteorological standard height (1.5-2 m); it is often used in this sense in North America. This usage allows all alpine zones to be ...

Crocus is a genus of flowering plants in the iris family comprising 90 species of perennials growing from corms. Crocus species are native to woodland, scrub, and meadows from sea level to alpine tundra in central and southern Europe, North Africa and th
