“…The adoption of the WFD has led to the intensive development of monitoring methods using all major groups of aquatic organisms [1], making the EU member states leaders in comprehensive ecological studies of aquatic ecosystems as a determinant of environment quality. This approach has also been used for the development of biomonitoring systems in nonEU countries and even on other continents [2][3][4].…”

“…Macrophytes, as a vital component of aquatic ecosystems, are among the groups of organisms considered by the WFD for river assessment. Plants are sensitive indicators of the aquatic environment, able to detect eutrophication [2,[5][6][7][8][9], and to some extent also acidification [10], water flow [11], and morphological degradation [8]. Furthermore, aquatic plants respond to various other environmental factors, including light, temperature, and substrate [12].…”

The Macrophyte Index for Rivers (MIR) was developed in 2007, and it was one of the first biological methods developed in Poland under the requirements of the Water Framework Directive to assess the ecological status of running waters. It is based on the quantitative and qualitative evaluation of 153 indicator taxa. The aim of this study was to evaluate the ability of the MIR method to detect trophic degradation in rivers and to compare its efficiency with other macrophyte metrics. Our investigation was based on 100 sites, representing a very clear gradient from near oligotrophic to eutrophic conditions. The results showed that macrophytes can be distinguished in terms of their ecological requirements for nutrient concentration in water, and this can be used to develop an effective system of freshwater assessment. The MIR was shown to be the indicator most strongly correlated with various forms of nutrients, and it was demonstrated that calibration of the macrophyte method to local biogeographical conditions resulted in greater effectiveness of the assessment method.

“…The Biotic indices approach, which is originally developed by Karr and Dudley (1981), is a widely used method for evaluating anthropogenic pressures on aquatic and wetland ecosystems: Floristic Quality Assessment Index (FQAI) (Lopez and Siobhan Fennessy 2002), Integrity Biotic Index (IBI) (Miller et al 2006), Iberian Multi metric Plant Index (IMPI) (Ferreira et al 2005), Index of Plant Community Integrity (IPCI) (DeKeyser et al 2003), Index of biotic integrity in Itanhaém (MIBI-ITA) (Umetsu et al 2018), Plant Index of Biotic Integrity (PIBI) (Simon et al 2001), Plant-based index of biotic integrity (PIBI) (PIBI(M)) (Moges et al2016), Riparian Forest Quality index (QBR) (Munné et al 2003), Riparian Quality Index (RQI) (Del Tanago et al 2006; González del Tánago and García de Jalón 2006), Vegetation Index of Biotic Integrity (VIBI) (Mack 2007), and Vegetation-based index of biotic integrity (VIBI(Y)) (Yang et al 2018).…”

One of the important tools to evaluate the ecological quality of surface water is the Macrophytes indices based on the bioindication capacity of aquatic plants. In Mediterranean rivers (France, Spain, and Portugal), the development of some macrophytes indices like l’Indice Biologique Macrophytes Rivières (IBMR), the biological metric score (BMS), as well as the Fluvial Macrophyte Index (IMF) are founded on the determination of the indicator values of the floristic reference lists. The aim of this study was to test the impact of the eco-Mediterranean differences (from one country to another) on the indicator taxa by comparing the indicator values of the Euro‐ Mediterranean macrophyte indices. With this in mind, we explore the possibility of the introduction of the Euro‐Mediterranean macrophytes-based indices in Morocco (i.e. the hydrological basin of Sebou (HBS)) as a part of a preliminary attempt to develop the first Afro-Mediterranean macrophyte index. We confirm that the ecological amplitude and species optima vary between Mediterranean ecoregions, and indicator taxa differ between countries: There are medium to small correlations between Mediterranean indices: IBMR/BMS (p = 0.000, R2 = 0.57), IMF/BMS (p = 0.000, R2 = 0.34), and IBMR/IMF (p = 0.000, R2 = 0.30). Five species exhibit major differences in indicator values: Zannichelliapalustris and Potamogetonpectinatus have more eutrophic indicator values in France (IBMR) than in Spain (IMF). Potamogetonnodosus, Amblystegiumriparium and Lycopuseuropaeus have broader ecological amplitudes in Portugal (BMS) than in France (IBMR) and in Spain (IMF), where it is restricted to eutrophic conditions. Furthermore, the three indicator systems include different indicator-taxon numbers. The comparison of the HBS elaborated list with the Euro‐Mediterranean indices revealed the low level of common taxa approximately 6.76% of all indicator species used in the French index (IBMR), 10.48% in the Portuguese index (IMF) and 12.38% in the Spanish index (BMS). These results show the inadequacy of the trophic indices approach with the HBS conditions and thus the need for the development of an index based on biotic indices approach.

“…Two sets of variables (riparian and proximal LULC) were selected to describe the pressure gradient and to identify the less disturbed sites for each river type (Figure 3, Table S2). Riparian and proximal land use are recognized as relevant drivers of local ecological quality changes [45]. Riparian and proximal LULC data, termed hereafter as stressor variables, were assessed using an image-based approach, supported by a Geographic Information System (GIS).…”

In this study, we assess the potential of ants as bioindicators of riparian ecological health in two river types (upland and lowland type) located in the Catalonian region. We proposed to understand to what extent do metrics based on ant responses provide useful information that cannot be presented by traditional biophysical assessments while attempting an approach to creating an ant-based multimetric index (ant-based MMI) of the riparian ecological health. A total of 22 ant species were identified, and 42 metrics related to ant foraging activity, species richness, and functional traits were evaluated as potential core metrics of the index. Riparian features and proximal land use land cover (LULC) were used to distinguish disturbed from less disturbed sites. We found that ant communities strongly responded to human disturbance. When compared with an exclusively physical-based index for the assessment of the riparian health, the ant-based MMI was more sensitive to human disturbance, by also reacting to the effects of the surrounding LULC pressure. This study provides a preliminary approach for an ant-based assessment tool to evaluate the health of riparian corridors although additional research is required to include other river types and a wider stressor gradient before a wider application.
