2. The impact of forest management methods on the ectomycorrhizal community and implications for forest productivity in needleleaf forests
University essay from Lunds universitet/Centrum för miljö- och klimatvetenskap (CEC)Abstract : Ectomycorrhizal fungi (ECM) form symbiotic relationships with trees by connecting to the roots, procuring soil nutrients in exchange for carbohydrates, and are an important contributor to plant growth. The forestry practice of clearcutting can be detrimental to the ECM community by removing its source of energy and creating unfavorable soil conditions, acutely reducing ECM diversity. READ MORE
