Nutrient content in macrophytes in Spanish shallow lakes

The concentrations of N, P and C in the above-ground biomass of 14 dominant macrophyte species in shallow lakes in N.W. Spain were measured. The plants included macroalgae, aquatic (submerged and floating leaved) and emergent angiosperms. Significant differences among the species and among the group...

Description
Summary:The concentrations of N, P and C in the above-ground biomass of 14 dominant macrophyte species in shallow lakes in N.W. Spain were measured. The plants included macroalgae, aquatic (submerged and floating leaved) and emergent angiosperms. Significant differences among the species and among the groups of macrophytes were observed for the three nutrients. The macroalgae showed the lowest P (0.053% dry weight) and C (35.24% dry weight) content, whilst an impoverishment in N (1.38% dry weight) was observed in the emergent species. Only the macroalgae showed a strong association between N and P (r= 0.743, p
