“…Substrates characterised by a high proportion of fine sediment are frequently 71 dominated by taxa with low dissolved oxygen requirements (Angradi, 1999;Zweig 72 and Rabeini, 2001) and exhibit an absence of taxa vulnerable to fine sediment due to 73 impairment or damage of filter-feeding apparatus or delicate gills (Wood and 74 Armitage, 1997; Larson et al, 2009). In addition, some taxa may be excluded and 75 unable to colonise habitats where excessive fine sediment is present, for example 76 due to the absence of suitable materials for case building by caddisfly larvae (Higler,77 1975; Urbanič et al, 2005).…”

“…Geological diversity has also an important influence on the sediment composition that may result in a physical alteration of the riverbed (von Bertrab et al, 2013). Previous studies showed the influence of sediment on macroinvertebrate assemblages (Allan, 1995;Subramanian and Sivaramakrishnan, 2005) including fine sediments (Angradi, 1999). In particular fine sediments strongly characterize the HER15.…”

Key-words:HER, macroinvertebrate, monitoring, source distance, watercourse Increasing the river habitat safeguard level is one of the main actions proposed by the European Water Framework Directive in the field of biomonitoring. To do so, watercourses within the same hydroecoregions (that is, homogeneous areas based on climate, geology and topography) ought to be compared. In addition, the source distance was thought to play an important role in comparing rivers and then planning monitoring activities. The purpose of this study was to evaluate if both hydroecoregion and source distance affect the response (in terms of taxa assemblage) of one of the most used group in the river monitoring activities: the benthic macroinvertebrate. Here we proposed the comparative influence of hydroecoregion and source distance on the invertebrate assemblage in Mediterranean rivers of central Italy. Our statistical outputs highlighted how macroinvertebrate differed for both hydroecoregions and source distance ranks. In particular, no differences were found among sites of different (1) source distance ranks and (2) hydroecoregion (that is, when this two descriptors were analyzed separately), while the highest difference in the macroinvertebrate assemblage was observed between the same source distance ranks of different hydroecoregions. Our results showed how the use of both hydroecoregion and source distance should be considered for planning monitoring activities to properly manage rivers and water resources.

“…The three metrics (EPT* richness, % EPT*, and MCI) that optimised the difference between reference and pastoral or urban impact sites are widely recognised as being sensitive to a range of anthropogenic stressors (e.g., Lenat 1984;Collier 1995;Angradi 1999;Collier & Smith 2005;Rois & Bailey 2006;Walsh 2006), and are commonly used in multimetric bioassessments (see Plafkin et al 1989;Barbour et al 1999;Maxted et al 2000;Quinn et al 2004). Although these metrics were strongly intercorrelated (r=0.79-0.90; author's unpubl.…”

Integrating multiple metrics derived from stream macroinvertebrate communities into single scores that reflect ecological condition can bridge the needs of multiple groups using biomonitoring data. Macroinvertebrate metrics from 511 Waikato, New Zealand, stream samples were standardised by their maximum observed value. Metric redundancy and optimisation processes identified three standardised metrics from an initial set of 17 that provided greatest discrimination between reference sites and those influenced by urbanisation or high levels of pastoral development: the richness of Ephemeroptera, Plecoptera and Trichoptera excluding Hydroptilidae (EPT*), % EPT* and the macroinvertebrate community index (MCI). The mean of these standardised metrics was used to calculate the average score per metric (ASPM). Narrative condition bands were developed based on the lower SD of individual metrics for reference samples to distinguish "very high" values, and metric quartiles between this point and a hypothetical worst-case community were used to define "high", "moderate", "low", and "very low" bands. When compared with its component metrics, the ASPM distinguished reference conditions and low-moderate levels of catchment modification and local habitat degradation more accurately than EPT* richness or MCI, and displayed lower temporal variability within reference sites than either EPT* metric. The ASPM was calculated for an independent test data set of urban and reference sites which, respectively, were allocated to low-very low and high-very high narrative condition bands. This analysis suggests that prudent application of the ASPM can provide a parsimonious and effective screening tool for assessing the condition of wadeable streams where more complex methods are not practical.
