The Snow Must Go On: Ground Ice Encasement, Snow Compaction and Absence of Snow Differently Cause Soil Hypoxia, CO₂ Accumulation and Tree Seedling Damage in Boreal Forest - Fig 5

<p><b>Effect of snow manipulation on main shoot winter survival (a) and shoot growth (b) at the end of the growing season (September 30, 2014).</b> An asterisk indicates statistically significant difference with AMB plots at p < 0.05. Values are means ± SE (n = 10).</p

Air temperature and effect of snow manipulation on soil temperature.

<p>Mean daily air (2-m height) and soil (humus layer) temperatures during winter 2013–2014 (a) and close-up at the time of snow melt (b). Values are mean of 3 blocks. Snow watering occasions are indicated. Blue arrows = cold spells, red arrows = warms spells.</p
