ARCTIC Summer Air Temperature and Number of Vascular Species in Arctic Canada
ABSTRACT. Exceptionally high correlations (r = 0.90-0.97) between number of vascular species and various indices of summer warmth at 38 localities in the Canadian Arctic support Young’s contention that summer thermal regime is th ost important ecological factor controlling the broad zonation of arct...
