Most peculiarly, large areas of northern tundra highlands fall outside of the two recent subdivisions of the tundra biome. We ...
Although there are various types of tundra, the term is most commonly associated with the Arctic and Antarctic regions characterised by permafrost. 2.4. High elevation treeline The correct partitioning of the Afroalpine and Afromontane regions (and associated flora and vegetation) hinges in part on ...
The region surrounding the town of Churchill, Manitoba, lies at the intersection of the tundra and boreal forest biomes, making it an ideal site for investigating ecotone biodiversity. Previous studies of hymenopteran subtaxa [1, 2] and aquatic insects [3, 4] have increased previous species ric...
U.S.A., where rocks and fossils of this age are known. These rock strata and fossils were formed during the middle Permian period, and as part of the recent revision of Permianstratigraphy(in order to attain a standard global correlation) the old division of lower and upper Permian has be...
1. Knowledge about the distribution and types of wetlands is in high demand by ecosystem modellers for full greenhouse gas accounting. The scope of this paper is to demonstrate the suitability of satellite radar data for the delineation of wetlands in the tundra and boreal forest biomes of ...
tundraSummary1Climate change in cold biomes not only involves higher summer temperatures, but also warmer springs and more winter precipitation. So far, little is known about species responses to these seasonal components of climate change.2We experimentally manipulated spring and summer temperatures and...
