TAXONOMIC COVERAGE:
Organisms studied
 
Methods:Soil cores were taken to the frozen layer or to the length of corer. At crest and riparian sites, frozen layer could not be reached. Cores were devided into different soil layers by cutting the cores with a knife, brought back to lab and sotred at ~4 degree C until they were processed (within 24 hours from the end of collection). Rock and live-root contents were plucked by hand and soils were dried to determine soil's bulk density. Total N and d15N were determined for ground soils.

Each core was separated by layer and numbered: 1) green, 2) next 10cm, 3) next 10 cm, 4) the rests (mineral soil was separated if there were any). For CR soils of 1-Jul-2003 samples, layer 1 and 2 (green and next 10cm) were not separated.
