This chapter focuses on the overall structure and major functions of contrasting tundras near Toolik Lake. It describes and compares key physical, chemical, and biological controls over the distribution and function of these ecosystems. It discusses timescales and trajectories of system-level change in response to changes in the controls. It considers how current and anticipated changes in climate affect the dynamics of soils and soil biota in arctic tundra ecosystems. It also predicts how the expected changes in global and arctic climates may alter the landscape and terrestrial ecosystems near Toolik Lake, and suggests priorities for future research.

Keywords:   tundra, Toolik Lake, ecosystems, climate, soil biota, terrestrial ecosystems, arctic climates
