PPT-How do soil temperature fluctuations affect water content?

Winter Ecology Course CU Mountain Research Station Spring 2015 Evan Franklin Soil Temperature Water Water in the winter season is a major limiting nutrient for many organisms particularly in an arid alpine environment Snowpack plays a major role in hydrating an alpine plant community.
