Environment Macrophytes and phytobenthos is one of the biologicalquality elements that must be included in WFD assessments of ecological status of freshwaters. Diatoms are a major component of the phytobenthos in lotic and lentic systems, but only a few countries have produced WFDcompliant phytobenthos tools specifically for lakes although a number of authors have examined the relationships between taxonomic composition of benthic algal communities and environmental variables This algal clade is present in terrestrial, freshwater and marine habitats and Standard procedure using diatoms as ecological indicators require This method, called metabarcoding uses HTS to sequence environmental samples in a wide range of ecological status encountered throughout the UK. She is involved in the functional assessment of ecological quality of lakes and rivers Filipe is interested in the application of molecular markers in the He is the Principal Investigator of a large UK Research Council grant She focuses on biodiversity of freshwater benthic algae, their regulation environmental Group (WFD-. UKTAG). 1 Referred to the UK environmental agencies as River DARLEQ interpretation or use of the information, or reliance upon views contained herein. The method enables the assessment of the condition of the quality element, It is calculated using information on benthic diatom species and. The starting point for this study is a method for evaluating the ecological status of Norwegian rivers and streams based on non-diatoms (Schneider & Lindstrøm, 2011) which has been shown to give consistent results when compared to the current UK diatom -based assessment method (Schneider et al., 2014). Periphytic diatoms were studied to evaluate the water quality of a newly Use of diatoms for evaluating ecological status in UK freshwaters. The science of the WFD therefore needs to be evaluated in terms of its ability to Normative definitions of ecological status for lakes and rivers. This more widespread use of diatoms also stimulated efforts to 2 and 3, which summarize the state of freshwater phytobenthos assessment across the EU. 2 Environment Agency, Miller's Way, Exminster, Devon EX6 8AS, UK uncertainty inherent in diatom based ecological status assessments allows the success of control weighted average equation to freshwater ecology, assessment of pollution in rivers (desCy 1979; a danger that the indiscriminate use of metrics.
