water cycle in the arctic tundra

Water and carbon cycles in the Arctic tundra - Get Revising Predicted increases in shrub abundance and biomass due to climate change are likely to alter components of the Arctic hydrologic budget.

-40 Further into the Arctic Ocean, there are more reasons to doubt the potential benefits of warmer temperatures and greater freshwater circulation. The permafrost prevents larger plants and trees from gaining a foothold, so lichens, mosses, sedges and willow .
