Seasonal variation in fungal biomass : the effects of soil temperature and moisture in a boreal forest
Climate change involves a series of events promoted by elevated levels of atmospheric CO2, such as increased temperature and changes in seasonal precipitation patterns, soil temperature, moisture and nutrient availability. Soils in boreal forests are often well-drained and not underlain by permafros...
