“…Over the years, the method has been further developed and modified by Ciecierska ( 2004a , b , c , 2006 , 2008 ), and within this study, it was fully adapted to WFD requirements as the Ecological State Macrophyte Index (ESMI).…”

The paper introduces the Ecological State Macrophyte Index (ESMI), a method compliant with the Water Framework Directive (2000/60/EC) for assessing the ecological status of lakes based on macrophytes. A description of the elaboration of macrophyte metrics, relevant reference conditions and a classification system for two types of high-alkalinity lowland lakes (stratified and polymictic), and a customised field survey procedure based on belt transects are presented. The ESMI evaluates two aspects of macrophyte community: taxonomic composition (index of evenness J) and abundance (colonisation index Z), which are combined into one multimetric. ESMI values range from 0 to 1, where 1 denotes pristine conditions and 0, highly degraded habitats. The high/good class boundary (H/G) was set at the first quartile of ESMI values of reference lakes. For the other classes, boundaries were set by dividing the range of ESMI values between the H/G boundary and the minimum value recorded in the dataset in a logarithmic scale into four. The ESMI correlated best with water transparency (Pearson’s R = 0.62 in stratified lakes and 0.79 in polymictic ones), whereas the correlations with phosphorus and nitrogen concentrations were somewhat weaker (R = −0.48 to −0.57). Based on the results of international intercalibration, the original class boundaries were modified (merged for stratified and polymictic lakes, the good/moderate boundary tightened to approximately 20 %), to make ESMI-based assessment results comparable with the outcomes of other European methods.Electronic supplementary materialThe online version of this article (doi:10.1007/s10661-014-3799-1) contains supplementary material, which is available to authorized users.

“…As for the "pressure-response" curve, both H and J were logarithmically and negatively correlated with TP, but were linearly and positively correlated with ZSD/ZM. In this study, we eventually adopted J rather than H to represent diversity in the subsequent analysis because J can represent simplification of macrophyte communities resulting from eutrophic pressure (Ciecierska, 2006;Ciecierska and Kolada, 2014). In non-disturbed ponds (Pond 6,7,8,9,13,14,15,16), H may reach Hmax during natural succession, thus the value of evenness J is approximately to 1.…”

Aquatic macrophytes in ponds are considered as reliable indicators for detecting eutrophication pressure. In this study, the spatial distribution of total phosphorus (TP) and the ratio between transparency and water depth (ZSD/ZM) were characterized in Lake Baiyangdian, north China. Total P and ZSD/ZM were adopted to represent eutrophication pressure. The macrophyte indicators including richness of different species, diversity /evenness, biomass, and relative abundance for submerged/emergent (RAsub/eme) and sensitive/tolerant submerged species (RAsen/tol), were measured for each of the 38 ponds in the study area. Results showed that except richness of emergent and floating-leaved species, other macrophyte indicators were significantly correlated with TP and ZSD/ZM. Among them, evenness, biomass, RAsub/eme and RAsen/tol were selected to evaluate pond status because of their stronger response to TP.To evaluate the status for each pond, a scoring system was created by integrating TP and the four selected macrophyte indicators. We suggest that, control of external pollution sources and internal pollution sources, especially surface runoff from cropland reclamation and intensive use of fish feed from aquaculture, should be the focus of local managers. Inferred from the response of submerged species abundance to light availability, the value of ZSD/ZM should be no less than 0.52 to restore submerged species in eutrophic ponds.

“…When all habitat conditions are known, the distribution of plant species can be satisfactorily provided (Guisan and Zimmermann, 2000). Recently, many efforts have been made in developing a biotic index based on macrophytes and predictive models that can be used as management tools in monitoring the quality of water bodies (Camargo et al, 2003;Ciecierska, 2006;Clayton and Edwards, 2006;Joye et al, 2006;Beck et al, 2010;Kocic et al, 2008;Penning et al, 2008a, b;Søndergaard, 2010).…”

Aquatic macrophytes as indicators of water quality in subtropical shallow lakes, Southern Brazil

AIMS: We evaluated the potential of aquatic macrophyte communities as bioindicators in six small shallow lakes. METHODS: The sampling was conducted monthly for one year, during which all macrophytes were surveyed, and the water temperature, dissolved oxygen, pH, conductivity, total alkalinity, chlorophyll-a, suspended matter, total nitrogen (Nt) and total phosphorus (Pt) were measured. RESULTS: In total, forty-three species were recorded, and there were significant differences in the species richness and limnological conditions among the lakes studied. A canonical correspondence analysis showed that the concentration of nutrients (Nt and Pt), chlorophyll-a, suspended matter, dissolved oxygen and pH were the most important predictors of the distribution of macrophytes. Some emergents were related to the high concentration of nutrients, chlorophyll-a, and suspended matter. Moreover, the most submersed species were associated with environments with low nutrient concentrations and the lowest values chlorophyll-a and suspended matter. In addition, some species submerged and floating were related to low values pH, alkalinity and dissolved oxygen. Limnological differences between lakes may be cited as the main causes of the observed heterogeneous distribution of macrophytes. CONCLUSIONS: These results indicate the importance of limnological characteristics of the different environments in the macrophyte community composition and the potential role of this community as a bioindicator in shallow lakes in southern Brazil.
