摘要: a b s t r c The aim of this study was to derive Macrophyte Nutrient Index for standing waters in Serbia, based on the LEAFPACS method and correlate it against existing Lake Typology. A single data matrix 46 species 1463 sample quadrats compiled from two datasets: revised phytocenological database given according Braun-Blanquet Cover Abundance Scale collected during summer months 2009, 2010 2011 at 31 lakes Serbia. nutrient indices (MSI) lake hydrophytes were calculated using Reprediction Algorithm N- Ellenberg's values. (LIMNIS) as weighted average MSI values Serbian lakes. Correlation between rescaled original N-values strong (0.82), same applies root-mean-square error value (0.75). Moderate LIMNIS derived meso-oligotrophic lakes, well eutrophic swamps fens Danube floodplain. In manner, classified showed relatively higher values, those recognised potential conservation resources characterised by moderate or low scores. Median six Groups differed less than one unit, which confirmed similarity previously Types. © 2012 Published Elsevier Ltd.
