“…In general, chironomids do not reflect the effects of the acidification stress in the investigated lakes in such a dramatic way as Ephemeroptera and Plecoptera (Vrba et al, 2003). Some studies (e.g., Meriläinen & Hynynen, 1990;Walker et al, 1991;Olander et al, 1997) did not find a significant relationship between S474 P. Bitušík & M. Svitok chironomid fauna and lake water pH, especially when pH gradient was small.…”

“…Both the lakes are the most productive systems among the investigated lakes (Nedbalová et al, 2006). Chironomid assemblage from Plešné Lake is remarkable because of the presence of three species of the genus Zavrelimyia, Parakiefferiella sp.…”

“…The lake ecosystems responded to the acidification stress differently according to their catchments characteristics and buffer capacity. This means that Nedbalová et al (2006) recognised two categories of lakes following their acidification status in 2003. Chironomid data are correlated with alkalinity as a surrogate of pH, but it should be stressed that it is difficult to discern the effects of anthropogenic acidification in these lakes with humic and naturally acid water.…”

“…Plešné Lake differs from the others because it has the highest level of productivity, heterotrophic microbial and plankton biomasses. Furthermore there are differences in some aspects of chemistry, and structure of phytoplankton (Nedbalová et al, 2006). However, the ordination model was not changed even when Plešné Lake was removed from the analysis.…”

Eight glacial lakes of the Bohemian Forest (Czech Republic and Germany) were characterised by the distribution of chironomids collected as pupal exuviae. Twenty-eight taxa were identified, including some faunistically interesting species of the region. Two-way indicator species analysis (TWINSPAN) was used to classify lakes according to their taxonomic composition. Canonical correspondence analysis (CCA) and multiple regression were used to relate the chironomid assemblages to two sets of explanatory variables: (i) local environmental variables, and (ii) broad-scale spatial variables. The TWINSPAN classified the lakes into four groups, whereas presence/absence of three taxa was indicative for this classification. The CCA of assemblage composition on environmental variables showed that chironomids respond significantly to altitude and alkalinity. The ordination of composition data on geographical variables revealed strong longitudinal gradient in chironomid distributions. Altitude and alkalinity accounted for 36.2% of the total variation, while the geographic gradient explained 20.5%. As revealed by the variation partitioning procedure, the significant effect of these variables was, in large part, independent of each other. Overall taxonomic richness appeared to be governed by altitude only. Causal ecological and historical factors underlying these results are discussed. This paper may provide a basis for hypothesis testing in future research of the Bohemian Forest lakes.

ABSTRACT1. Historically, ecological assessment of lakes has depended on open-water chemical and phytoplankton analysis, with trophic status determined by chlorophyll a and total phosphorus following the general protocol of the OECD lake classification scheme. This has been accompanied by a prevailing opinion that the littoral zone of lakes is too heterogeneous to allow meaningful interlake comparisons.2. Council of the European Communities Directive 2000/60/EC establishing a framework in the field of water policy (the Water Framework Directive) requires a broader approach to ecological assessment, including the need to incorporate a range of biotic variables. This paper describes the results of a monitoring programme designed to determine within-and among-lake variation of macroinvertebrate communities found in defined mesohabitats of 22 lakes incorporating a range of lake types. Three sampling approaches were applied to the study.3. Triplicate macroinvertebrate samples from a cobble/pebble mesohabitat of 11 lakes showed that community composition from a standard habitat was robust.4. Twinned samples from contrasting habitats of pebble/cobble and macrophyte dominated mesohabitats of 21 lakes had greater similarity within than among lakes. This showed that even across contrasting habitat structure, macroinvertebrate assemblages can provide a reliable lakespecific indicator.5. Multivariate analysis of replicate samples from 15 visually distinct mesohabitats in one lake showed that within-lake variation could, nevertheless, be identified as distinct clusters of invertebrate assemblages.6. Conclusions from the work are that variations within lakes were nested in among-lake variation across a range of lake types, and that macroinvertebrate assemblages can provide meaningful assessment of ecological differences across lakes. Monitoring can, however, produce a substantial amount of 'noise' from the data that reflects the complexity of macroinvertebrate community structure in littoral zones. It is recommended that incorporation of macroinvertebrates in ecological assessment is most useful when confined to well defined mesohabitats rather than attempt to incorporate a complete range of mesohabitats within a single lake.
