1. Increased nutrient loading to wetlands often results in an increase in emergent plant biomass and a decrease in species diversity. While these patterns are broadly predictable, the underlying mechanisms are unknown. We tested two related hypothese by growing plants under standardized conditions: (1) emergent plants typical of infertile wetlands have higher tissue nutrient contents than plants from fertile wetlands and (2) plants belonging to different functional groups (ruderal, interstitian and matrix) have different tissue nutrient contents. 2. Concentrations of N and P in above-ground phytomass were measured for 41 plant species, from contrasting kinds of wetlands, after one season of growth in excess fertilizer (NPK in ratios 7:11:27 and 15:0:0). Tissue nutrient concentrations ranged from 0.25 to 2.14% dry weight for N and from 0.13 to 1.07% dry weight for P. 3. There was no significant difference in nutrient content between plants from infertile sites and plants from fertile sites. However, plants with ruderal life history traits (e.g. annual or functional annual/fast-growing) had significantly lower N and P tissue concentrations than plants having interstitial or matrix life history traits. Interstitial perennials had significantly higher N concentrations than matrix perennial. Therefore, plant functional groups are likely to respond differently to eutrophication. 4. Plant size, estimated by maximum species biomass, explained 67% (r2 = 0.67, P<0.001, n=31) of the variation in N tissue concentrations but only 5% of the variation in P tissue concentrations. Menos1.
