shows gradients in pedogenic pro-
cesses northward from the forest-tundra across the Low-Arctic and Subarctic
Tundra, the Mid-Arctic Tundra, and the High Arctic Barrens (Goryachkin et al.
2004
). The figure shows a reduction in redoximorphism (gleization), melaniza-
tion (organic matter accumulation), podzolization, and textural differentiation
