Above the tree line there is a zone that is generally called alpine tundra.Immediately adjacent to the timberline, the tundra consists of a fairly complete cover of low-lying shrubs, herbs, and grasses, while higher up the number and diversity of species decrease until there is much bare gro...
Tundra is a geographical term for an area where plant and animal development is hindered by extreme low temperatures, stunted growing seasons and a lack of nutrient availability. There are two main areas of tundra on the earth: the Arctic and Alpine tundras. The Arctic tundra is near to the...
Analyses were made of the carbohydrate content of roots, rhizomes, and shoots of certain plants in the alpine tundra region of the Medicine Bow Mountains, Wyoming, from the beginning of one growing season until the start of the following one. Principal species investigated were Saxifraga rhomboid...
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 ...
Plant-microbe competition for soil amino acids in the alpine tundra: effects of freeze-thaw and dry-rewet events Amino acids have been shown to be a potentially significant N source for the alpine sedge, Kobresia myosuroides. We hypothesised that freeze-thaw and dry-r... LRK Monson - 《...
On the ecology and biogeography of alpine tundra arachnids In the course of the discussion about the effects of manmade Climate Change on ecosystems, alpine regions of the earth have become a major focus. Alpine ecosystems are generally considered to be especially sensitive towards environmental......
The rapidly warming temperatures in high-latitude and alpine regions have the potential to alter the phenology of Arctic and alpine plants, affecting processes ranging from food webs to ecosystem trace gas fluxes. The International Tundra Experiment (ITEX) was initiated in 1990 to evaluate the effec...
