“…A. veneta was reported as an indicator of moderate to low biological status [57,58], which is in agreement with the higher phosphorus concentrations observed and poor ecological integrity (class C and D) based on IDEC scores. E. subminuscula is also reported as a nutrient-tolerant species [57,61,62].…”

“…One should be careful with the interpretation in this situation because the IDEC scores most likely reflect the strong dominance of A. minutissimum and B. vitrea, together making up for 60-90% of the assemblages at these sites. While these species are indeed good indicators of lower nutrient concentrations [57][58][59], they are also known to be tolerant of metal contamination (see above references). However, other dominant taxa in this group can tolerate higher nutrient levels (e.g., Nitzschia palea, Navicula veneta, Encyonema silesiacum) which explains lower IDEC scores at CCC.…”

Sudbury (Ontario, Canada) has a long mining history that has left the region with a distinctive legacy of environmental impacts. Several actions have been undertaken since the 1970s to rehabilitate this deteriorated environment, in both terrestrial and aquatic ecosystems. Despite a marked increase in environmental health, we show that the Junction Creek system remains under multiple stressors from present and past mining operations, and from urban-related pressures such as municipal wastewater treatment plants, golf courses and stormwater runoff. Water samples have elevated metal concentrations, with values reaching up to 1 mg·L −1 Ni, 40 µg·L −1 Zn, and 0.5 µg·L −1 Cd. The responses of diatoms to stressors were observed at the assemblage level (metal tolerant species, nutrient-loving species), and at the individual level through the presence of teratologies (abnormal diatom frustules). The cumulative criterion unit (CCU) approach was used as a proxy for metal toxicity to aquatic life and suggested elevated potential for toxicity at certain sites. Diatom teratologies were significantly less frequent at sites with CCU values <1, suggesting "background" metal concentrations as compared to sites with higher CCU values. The highest percentages of teratologies were observed at sites presenting multiple types of environmental pressures.

“…The IPS is robust enough, neither too sensitive to the substrate type, nor the light and nor the current conditions. For this latest feature, it can be use in the ecological status assessment of standing waters, as well, as it is used in Finland and Sweden already (Kelly et al 2014 …”

The Indice de Polluo-Sensibilité Spécifique (IPS) is one of the most frequently used diatom index. Beside this, according to some studies in streams and small rivers the diatom ecological guilds might be effective tools for ecological quality assessment in the future, but the usability of them is not always clear. Our main goal was to compare the robustness of the IPS index and diatom ecological guilds in a large river. For this i) a temporary study was carried out to investigate if there were some differences between how the nutrient content affected the IPS values and guilds proportions in the Danube River; ii) spatial studies were conducted to investigate the effects of the different water depths (different light intensity and current velocity) on biological metrics (IPS and guilds, as well); iii) we studied whether the IPS index or guild proportions were influenced more by the substrate type.As for the results of the temporal study only the motile and planktic guilds had significant connections with phosphate-phosphorus concentration. However, the high profile and the low profile taxa showed correlations neither with nutrient concentration nor water discharge. Nevertheless, the higher abundances the low profile guild reached the lesser values of the IPS index were. In spatial studies the guild abundances (especially the motile taxa) altered in different water depths. This could be caused by 2 different microhabitats characterised by disparate current velocity, and by different types of bed material along the cross-section. Contrary to guilds, there were no relevant differences in IPS values along the cross-sections. We experienced similarities in the study on shells and in spatial study: there were significant differences between guild abundances on different shell surfaces, but not so in the IPS. On the whole the IPS is robust enough to be a suitable index for the ecological water quality assessment and diatom ecological guilds could not be used instead of the diatom index (IPS) in large rivers. However, the trait based methods could be useful supplements of the ecological status assessment.

“…De indicatieve kracht van diatomeeën in meren ligt mogelijk voornamelijk in het inschatten van de trofische status (i.e. nutriëntenconcentraties; JRC 2014; Kelly et al 2014), en de monitoring van fytobenthos zou dan waarschijnlijk de resultaten bekrachtigen van andere biotische of abiotische componenten die gerelateerd zijn aan nutriëntenconcentraties. Interkalibratie van de fytobenthosmethodologie tussen lidstaten toonde een sterke relatie aan met nutriëntenstatus, en minder met saprobiegraad (organisch materiaal; Kelly et al 2014).…”
