“…Besides, several water quality assessment tools based at least partially on microcrustaceans already exist (e.g. Gannon and Stemberger, 1978;Van Tongeren et al, 1992;Lougheed and Chow-Fraser, 2002;Eyto et al, 2003;Kane and Culver, 2003).…”

ABSTRACT1. According to the European Water Framework Directive (2000/60/CE) tools are required to evaluate wetland ecological quality. In this context, a biological index to evaluate water quality (QAELS) is proposed for Mediterranean wetlands in Catalunya (NE Iberian peninsula).2. The study was carried out in 99 shallow lentic ecosystems, situated below 800 m a.s.l. and with a maximum depth of less than 6 m. At each sampling point, a range of water parameters was measured (temperature, conductivity, pH, dissolved oxygen, chlorophyll a, dissolved nutrients and total nutrients) and data were gathered on invertebrate taxon composition (collected with a dip-net of 250 mm mesh size).3. A previous classification of wetlands in that area was required to obtain QAELS. The QAELS index is obtained by: (1) the relative abundance of each microcrustacean taxon (Cladocera, Copepoda and Ostracoda) weighted by an ecological quality requirement coefficient, which is obtained for each taxon by means of partial canonical correspondence analysis (ACCO index); and (2) the taxonomic richness of crustaceans and aquatic insects (RIC index).4. Several taxonomic resolutions were also tested in order to determine the simplest identification level that gives acceptable results in further applications of the QAELS index. It is concluded that the composition of microcrustacean assemblages (ACCO index) is useful for assessing the water quality of Mediterranean wetlands.5. The RIC index improves the relationship of the QAELS index to water quality variables, avoiding possible anomalous values that could be obtained when using the ACCO index alone.

“…Macrophyte-associated taxa, mainly Chydoridae and species such as Diaphanosoma brachyurum and Sida crystallina, constituted a considerable part of the species richness. C. rectirostris and P. trigonellus were the only two chydorid species found in Kacˇlezˇsky´pond whose occurrence did not exceed 20% in 66 European lakes in a study conducted by de Eyto et al (2003).…”

-Seasonal dynamics of zooplankton were investigated in three different habitats of the shallow and temperate Kacˇlezˇsky´pond (Czech Republic) during [2003][2004]. The studied habitats included the limnetic zone and two littoral zones, each dominated by a different type of emergent macrophyte, reed grass (Glyceria maxima) and common reed (Phragmites australis). Species richness (calculated as number of taxa) was higher in both littoral zones than in the limnetic zone. The seasonal development of limnetic and littoral zooplankton communities differed. In contrast to the two littoral zones, close correlation with chlorophyll-a concentration was found for rotifers and cladocerans in the limnetic zone. Moreover, cladocerans inhabiting littoral areas (mainly Bosmina longirostris) reached annual maxima during spring when chlorophyll-a concentrations were low.

“…Furthermore, the identification level in the present study for phytoplankton, zooplankton, and invertebrates was not species but family and/or order level. According to De Eyto et al (2003) the relationship between Chydoridae from the lakes sampled in 2000 and lake ecological quality was more apparent at species than at community level. However, other studies (Marchant, 2002) have demonstrated that identification to species level is not always necessary for the assessment of ecological quality.…”

The European Water Framework Directive (WFD) requires that all aquatic ecosystems in their member states should reach 'good' ecological quality by 2015. To assess ecological quality, the WFD requires the definition of reference conditions using biological, physical and chemical indicators and the assignment of each water body to one of five quality classes using these indicators. Elaborate assessment schemes using large sets of variables are now being developed. Here we address the question whether all this is really needed and what the simplest assessment approach would be for the case of shallow lakes. We explore the relationships between the quality class assigned to a lake by experts in shallow lake ecology and a rich set of biological, physical, and chemical data. Multinomial logistic regression analyses were carried out based on data from 86 shallow lakes throughout Europe that were sampled in 2000 and/or 2001. Ecological quality of shallow lakes judged by experts was strongly correlated to physical and chemical variables associated with light regime and nutrients and much less to biological variables.Our regression model showed that ecological quality of this set of shallow lakes judged by experts could be predicted quite well from water transparency expressed as Secchi depth and that other variables did not contribute to it
