Soil respiration at a reference temperature (10°C) in relation to A mean annual soil temperature (r2 = 0.69, P < 0.001), B soil C content in the uppermost 20–25 cm of the soil (r2 = 0.50, P < 0.05), C peak leaf area index (r2 = 0.55, P < 0.01) and D annual gross primary productivity (r2 = 0.88, P = 0.001). Meadows (▲), pastures (●), unmanaged Northern grasslands (◇).
