Vegetation structure in gullies developed by the melting of ice wedges along Kolyma River, northern Siberia
Vegetation structure was surveyed in gullies developed by the melting of ice wedges along the Kolyma River, northern Siberia, using 72 50 × 50 cm plots. The mean total plant cover was approximately 50% on gley soils, which were only distributed in the gullies. Based on TWINSPAN cluster analysis, fou...
