As climate warms, changes in the carbon (C) balance of arctic tundra will play an important role in the global C balance. The C balance of tundra is tightly coupled to the nitrogen (N) and phosphorus (P) cycles because soil organic matter is the principal source of plant-available nutrients...

Helicopter yarding systems have become a popular tool in
removing timber from steep slopes, sensitive soils, limited access
areas, and environmentally sensitive stands. Little is known about
the system's dynamics. This study is part of a research project to
explore "advanced" logging systems as to their economic efficiency
and environmental...
