“…A previous study from southern China (Hu et al, 2013) and other studies from different environments (Abonyi et al, 2014;Petar et al, 2014) consistently showed that MFG were able to provide an ecological classification of phytoplankton fully comparable with that obtained with FGs (Reynolds et al, 2002). The present study showed a strong concordance between the MFG and genera-based ordinations, and an increasing discordance between the genera-based configurations and those based on higher taxonomical units (i.e.…”

Water quality improvement and suppression of cyanobacterial blooms were planned in a eutrophic reservoir in southern China through ecological engineering measures from 2006 to 2011. This consisted in (i) a hydraulic resetting of inflows and outflows to increase the distance between inlet and outlet and the water residence time in the reservoir, and in (ii) the installation of floating frames hosting wetland vegetation to promote an alteration in phytoplankton composition. The environmental changes were therefore followed through the analysis of biotic responses in phytoplankton assemblages. Ecological engineering was effective in reducing phytoplankton total biomass, in re-establishing more diversified phytoplankton assemblages and in avoiding cyanobacterial blooms. These changes may be considered as an improvement of the reservoir water quality. However, trophic state parameters and the dynamics of dominant species were not sensitive enough in describing the environmental changes that had occurred when the eco-engineering measures were implemented. These were more effectively tracked by the dynamics followed by phytoplankton MorphoFunctional-Groups and by their classification based on Competitors, Stress tolerants and Ruderals strategies. Although providing immediate positive effects, the ecoengineering was temporally limited, highlighting the importance of constant management in the context of long-term oriented remediation techniques.

“…Due to the underlying carbonate bedrock, Plitvice Lakes are hard-water lakes with a large population of calcifying cyanobacteria (Plenković-Moraj et al 2002;Žutinić et al 2014), and are characterized by conditions favourable for calcite precipitation (SIcalc values range from 3 -10 and pH values range from 8.0 -8.7) (Barešić et al 2011;Srdoč et al 1985). Calcite precipitation is highest between spring and autumn, and is lower in wintertime (Srdoč et al 1985).…”

“…Izaguirre et al (2012) also found greater explanatory power with the MBFG structure and concluded that this classification compared to FG, is more sensitive to certain aspects of the phytoplankton community that are important for ecosystem dynamics. Other authors also found better statistical results with the morphological structure when compared to other classifications (Petar et al 2014;Abonyi et al 2017;Lobo et al 2018). The advantages of morphological classification are the objectivity, the relative simplicity, and the independence from the taxonomic classification.…”

Functional classifications are important for studies with phytoplankton, because they are based on ecological or morphological characteristics. We tested the interference of the macrophyte coverage in taxonomic and functional structure of phytoplankton community. Twelve small reservoirs were visited in September 2015 and May 2016 in semiarid regions of Brazilian northeast. Water samples were collected and abiotic variables were measured using a probe. Macrophyte coverage was recorded using the dot method. The microalgae were classified using taxonomic classification (taxa), morphological functional classification (MBFG) and functional groups (FG). We found 242 taxa, 22 FG and the seven MBFG. Phytoplankton presented an average biomass of 3.8 mg L −1 and a richness average of 38 species in dry period, while during the rainy season the biomass value was 6.2 mg L −1 and the richness, 33 species. The macrophytes had the highest average cover during the rainy season (63%) than the dry season (32%). Spearman analyses showed no correlation between total macrophyte coverage and biomass and richness (taxonomic and functional) of phytoplankton (P > 0.05). However, the growth form of emergent and free-floating macrophytes were selected as explanatory variables in the CCA model performed with the MBFG classification. This model presented greatest explanatory power (57%) when compared to FG classification (21%) and taxonomy (20%). Considering our results, using the MBFG classification is recommended for studies with similar sampling design, because it presents greater explanatory power and expresses the relationship between phytoplankton and aquatic macrophytes.
