AB  - Due to the problem of identification, Chironomidae larvae, although very
   abundant, are often avoided or not properly used in bioassessment
   programs. The aim of this work was to test how different aggregation
   processes-taxonomic resolution and the random aggregation approach (best
   practicable aggregation of species-BestAgg) affect the analysis of
   chironomid communities regarding any information loss. The
   self-organizing map method, together with classification strength
   analysis and Spearman's rank correlation, revealed that the genus-level
   and BestAgg-abundance matrix most accurately approximated the
   species-level community pattern. The subfamily-level dataset was
   ineffective at presenting the chironomid community structure, with a
   substantially lower concordance with the species-level dataset. The
   biologic environmental gradients analyses presented the same set of
   important environmental variables for the species-level, genus-level,
   and BestAgg-abundance matrix. The indicator values analysis showed that
   indicator genera provide information very close to that gained from
   species indicators. According to our results, the numeric relationship
   between species and higher taxa influences taxonomic scaling, limiting
   Chironomidae family aggregation, with acceptable information loss only
   up to genus level. In addition, the BestAgg approach, with the maximum
   level of aggregation, properly assesses the community structure and
   consequently describes environmental conditions.

AB  - We employed the self-organizing map (SOM) method to investigate the spatio-temporal pattern of the Chironomidae community in the Southern Morava River basin (Serbia) and to examine to what extent the Chironomidae community is affected by environmental factors. Additionally, this study explores the problems of utilizing chironomids in bioassessment programs. The SOM analysis of the chironomid community data produced 3 groups of sites. The indicator species analysis presented indicator taxa for two groups. Twenty taxa (at species, species group and genus level), according to the Kruskal-Wallis test, showed the most pronounced differences among the temporal units. Out of 15 measured environmental parameters, one-way ANOVA pointed out that 10 significantly differ between the groups. Elevation had the most important influence on the chironomid community, also affecting other environmental parameters. According to our findings, the winter season and the periods with high water level are the main sources of natural variability. To avoid such variability and to successfully incorporate Chironomidae in bioassessment programs, we suggest exclusion of the arguable months from monitoring programs.
