Effects of Canada Goldenrod Invasion on Soil Extracellular Enzyme Activities and Ecoenzymatic Stoichiometry

The rapid expansion of Canada goldenrod (Solidago canadensis L.) in China has drawn considerable attention as it may not only decrease vegetation diversity but also alter soil nutrient cycling the affected ecosystems. Soil extracellular enzymes mediate by catalyzing organic matter decomposition; however, mechanisms which alien plant invasion affect remain unclear. objective this study was to investigate responses enzyme activities and ecoenzymatic stoichiometry S. invasion. Several enzymatic related carbon, nitrogen, phosphorus were measured using a fluorometric method. Ecoenzymatic used proxy microbial metabolic limitations. appeared be associated with decreased substantial conversions carbon nitrogen changes limitations metabolism correlated alterations availability resource soil. These findings reveal that available nutrients regulate cause limitations, suggesting considerably affects biogeochemical processes.
