چکیده
Abstract Background Nutrient resorption is an important plant nutrient conservation strategy in wetlands. However, how shrub encroachment alters processes unclear temperate Here, we collected green and senesced leaves of common sedge, grass, species wetlands with high (50–65%) low (20–35%) covers the Sanjiang Plain Northeast China, assessed impact on leaf nitrogen (N) phosphorus (P) efficiency proficiency at both growth form community levels. Results The effects cover were identical among shrubs, grasses, sedges. Irrespective forms, increased reduced N proficiency, but did not alter P proficiency. effect differed between At level, decreased increasing because dominance shrubs lower over grasses Accordingly, community-level concentrations elevating cover, showing a decline Moreover, significant relationships indicate that by decreasing efficiency. Conclusions These observations suggest reduces highlight altered composition should be level
