“…Trichoptera, in agreement with recent studies (Couceiro et al, 2011;Leitner et al, 2015;Conroy et al 2016;Doretto et al, 2017). Although richness metrics are generally sensitive to natural variability and seasonality, and thus are influenced by the period of sampling (Bilton al., 2006), their combination diminishes this effect and thus increases the robustness of the multimetric index (Dahl and Johnson, 2004;Maloney and Feminella, 2006).…”

“…Conversely, some taxa (i.e., Chiromomidae, Oligochaeta) could benefit from the environmental conditions provided by fine sediment (Ciesielka, and Bailey, 2001;Cover et al, 2008). Also, trait-based classifications of macroinvertebrate taxa have been recently used to assess the response of macroinvertebrate assemblages to fine sediment conditions, with noteworthy results (Pollard and Yuan, 2010;Conroy et al, 2016;Wilkes et al, 2017). Many studies have demonstrated that specific functional groups of invertebrates are particularly affected by siltation (Rabeni et al, 2005;Longing et al, 2010;Doretto et al, 2016).…”

Highlights 14 Siltation results in alterations of the aquatic habitat and biological communities 15  To face these sediment-associated impacts specific biomonitoring tools are needed communities. In this study the correlation between fine sediment and several benthic invertebrate 32 community metrics was tested through a manipulative approach in alpine streams, where siltation 33 mainly results as a physical alteration (i.e., the clogging of substrate interstices) without the 34 influence of co-occurring confounding factors. We selected 12 candidate metrics, belonging to three 35 different categories: compositional, structural and functional. We first carried out a manipulative 36 experiment where artificial substrates were used to provide standardized conditions of siltation. All 37 candidate metrics were calculated for each artificial substrate and the selection of the best 38 combination of metrics was statistically performed with an information-theoretic approach. All 39 candidate metrics were calculated both at family level and also at a mixed level (family and genus) 40 in order to account for the systematic resolution. Then, data from a field study on alpine streams 41 affected by mining activities were used as independent dataset for testing the performance of the 42 selected metrics. We found that the total taxa richness, the EPT (Ephemeroptera, Plecoptera and

“…Although only recently introduced, several studies have utilised PSI scores for assessing sediment pressures (Poole et al, 2013;Glendell et al, 2014;Conroy et al, 2016a;Bradley et al, 2017;Extence et al, 2017). Extence et al (2017) for example, found using a national data set, a significantly strong (r 2 = 0.597) relationship between PSI scores and a channel substrate index (CSI) designed to assess levels of fine sediment.…”

“…Degradation of freshwaters resulting from excess inputs of sediment is a global concern (Richter et al, 1997;Malmqvist and Rundle, 2002;Dudgeon et al, 2006;Heino et al, 2020), with studies from New Zealand (Townsend et al, 2008;Ramezani et al, 2016), the United States (Rabení et al, 2005), United Kingdom (Extence et al, 2017), Canada (Benoy et al, 2012), Ireland (Conroy et al, 2016a) and Spain (Buendia et al, 2013) highlighting its impacts on aquatic biota. In the US for example, excessive sediment occurs in 15 % of river and stream length (USEPA, 2016).…”

“…Since its initial development, PSI has been applied in a variety of situations ( e.g. Bradley et al, ; Conroy et al, ; Gillespie, Brown, & Kay, ; Glendell, Extence, Chadd, & Brazier, ; Mathers, Chadd, Extence, Rice, & Wood, ; Poole, Bradley, Salazar, & Macdoonald, ; White, Hannah, House, & Beatson, ) and has also been subject to further analysis and development—E‐PSI (Turley, Bilotta, Extence, & Brazier, ; Turley, Bilotta, Krueger, Brazier, & Extence, ; Turley et al ., ), where empirical data and expert judgement are combined to refine the original PSI approach, while still being constrained by the original taxon fine‐sediment associations. The E‐PSI adjustments have further strengthened the relationship between river ecology and fine sediment.…”

Sedimentation of river beds is a key pressure impacting riverine ecological communities. Research has identified the need for new approaches to help demonstrate and quantify the impacts of excessive fine-sediment deposition on benthic macroinvertebrate populations. To help meet this requirement, the Proportion of Sediment-sensitive Invertebrates (PSI) methodology was developed and has been in operational use in the United Kingdom for several years. This paper presents a number of case studies, at both national and local scales, showing how the method can be used to identify point and nonpoint fine-sediment pollution, as well as demonstrating the analysis of a national dataset to describe the relationship between PSI and a channel substrate index.A novel approach to displaying PSI data alongside local ecological and hydrological information is also presented and interpreted, to illustrate how improved understanding of biotic and abiotic relationships and interactions can be readily accomplished. Excessive fine-sediment accumulation on river beds results in impaired ecosystem health globally. The case studies and examples presented here will provide confidence that the PSI method can form the basis for evidence gathering and analysis, both within and beyond the United Kingdom. The paper concludes with an overview of the use of PSI in catchment research and management, a consideration of the relationship of the metric with other macroinvertebrate indices, and a summary of refinements recently applied to the index.
