Researchers tested the response of proteolytic enzymes to manipulations of temperature, protein and nitrogen availability, and root abundance. They also examined whether these responses were influenced by presence of tree species that differ in their associations with soil chemistry and mycorrhizal fungi. This research was conducted in single tree species plots dominated by arbuscular mycorrhizal (fungus penetrates root cells) associated trees, sugar maple and white ash, or ectomycorrhizal (fungus forms sheath on outside of root tips) associated trees, eastern hemlock and American beech. The plots were located at the Harvard Forest in Massachusetts and the Pisgah State Park in New Hampshire.
