“…Water transparency, which is inversely related to pollution gradient and conductivity, is in particular one of the important parameters determining the diatom assemblages in aquatic ecosystems [60,66]. It is generally stated that there is a relationship between epiphytic algae and environmental variables, and submerged macrophytes have been recommended for routine monitoring [67]. We found a significant relationship with selected environmental variables in congruence with other studies [13,52].…”

“…(WC). In general, the relationship between epiphyton and water chemistry has been demonstrated many times (ács et al 1991, 1994kitner & Poulíčková 2003;Blanco et al 2004;HájKová et al 2011) and submerged macrophytes have been recommended for routine monitoring (Kelly et al 1998;Blanco et al 2004). We found significant relationship to selected environmental variables (water streaming, pH) in congruence with other studies (PotaPova & cHarles 2003;kitner & Poulíčková 2003;kovács et al 2006;FránKová et al 2009;yang & FloWer 2012).…”

Small streams and shallow ponds represent sensitive ecosystems and attached diatoms can serve as integrative indicator with fast response to environmental changes. Development of methods for ecological monitoring throughout Europe and their calibration for particular ecoregions are not finished yet and databases need to be filled by data from undersampled regions and overlooked substrates. The present study aims to explore the diversity of epiphytic diatoms in unexplored catchment areas with special attention to substrate specificity and distribution of unresolved diatom species complexes. Significant differences were found in diversity of both regions and water types (lotic/lentic). No significant differences were found in the case of substrates. CCA analysis showed significant influence of pH, water streaming (streaming/stagnant) and Lemna substrate to species composition. Surprisingly species complexes represent the majority of epiphytic assemblages with no significant differences between lotic and lentic waters or substrates except of Lemna. The high representation of complexes does not lead automatically to reduction of overall diversity of the sample.

“…Nitrate sensitivity was demonstrated for the diatom phytobenthos in many spring systems (e.g. Cantonati 1998;Fránková et al 2009;Angeli et al 2010;Hájková et al 2011). Nitrate in spring water is considered to indicate anthropogenic impact but is modulated by the degree of retention and transformation in the soil and subsoil, as well as biological uptake before and after emergence (Niedermayr & Schagerl 2010).…”

Diatom assemblages were examined from non-living substrates in thirteen springs supporting the Natura 2000 habitat type 'Petryfing springs with tufa formation' in the southern part of Flanders. More than 300 taxa were recorded, including some which appear to be particularly associated with this kind of environment. Even though a number of characteristic taxa and diatoms characterizing fast-flowing springs of more elevated terrain remained absent, local species richness was higher than reported from carbonate springs elsewhere in Europe. Relative abundance of 'Red List' taxa was, however, substantially lower. Taxon richness was not related to measured nutrients but increased with diatom-inferred trophic status. Assemblages consisted mainly of motile, small-celled species of Achnanthidium, Amphora, Caloneis, Planothidium and Stauroneis. Hygropetric rheocrenes presented a somewhat more distinct assemblage than helocrene and rheohelocrene settings, but overall, compositional metrics were similar among spring types. Assemblages were structured mainly along gradients of pH, major ions (in particular magnesium and potassium) and nitrate relating to calcite precipitation, aquifer and nitrogen supply. Besides substantiating broad similarities among Cratoneurion springs, the results provide arguments for a regionalized approach towards assessment of their diversity, community structure and conservation status.

Disentangling the effects of water chemistry and substratum structure on moss-dwelling unicellular and multicellular micro-organisms in spring-fens

Abstract: Water chemistry is known to be one of the most important factors controlling species composition of many macro-organisms in wetlands. It is unclear to what extent micro-organisms respond to water chemistry as
