“…We did not include the broken stick model because the model is characterized with a large number of species in intermediate dominance while the curve possesses an extremely flatted medium range along with slight up-bend at the left (5) part and down-bend at the right part (Magurran 2004). This pattern basically was not matched to the observed samples in this study: benthic macroinvertebrates from polluted streams are well known that a few tolerant taxa are selectively present in high abundance (Hellawell 1986, Rosenberg & Resh 1993, Wright et al 2000, Park et al 2007, Allan & Castillo 2007.…”

“…They reflect environmental changes in an integrative and continuous manner and have been widely used for ecological water quality assessment (Rosenberg & Resh 1993, Wright et al 2000, Park et al 2007, Allan & Castillo 2007. In this study we investigate species abundance patterns in benthic macroinvertebrates in polluted streams and elucidate how the SADs would characterize community structure and respond to environmental disturbances.…”

Benthic macroinvertebrates collected at seven different streams displaying different pollution levels were used to investigate species abundance patterns in polluted streams. Community response to disturbances in streams was analysed using species abundance distribution (SAD) for benthic macroinvertebrates across different levels of pollution. The slopes of rank abundance were characteristically steeper with decreasing species richness at the polluted sample sites, while the slopes were less steep with higher species richness at the clean or slightly disturbed sample sites. The SADs were broadly fitted to the log normal distribution in benthic macroinvertebrate communities across different levels of pollution. A geometric series was partly accepted for the communities at the severely polluted sites where new species could not be readily introduced. A power law was applied to the SADs, and the parameters reflected the states pertaining to the sample sites. The SADs were also efficient in revealing ecological state of communities where physico-chemical indicators could not be easily differentiated for stressful conditions in streams.

“…Although a great deal of research using various assemblages has been conducted for the evaluation of ecosystem health, only minimal information has been available for full evaluation of environmental and biological quality on the national scale, particularly in Korea (e.g., Park et al, 2007). In addition, relatively few studies have evaluated the response of multiple biological assemblages in biomonitoring studies, and even fewer studies have examined the relationship and intercorrelation of different assemblages' measures and their response to stress on multiple spatial scales (Hering et al, 2006;Flinders et al, 2008).…”

“…The European Water Framework Directive (European Commission, 2000) also advocates the use of these organism groups in assessment of the ecological integrity of stream ecosystems. As a result of differences in Macroinvertebrates are sedentary and have an intermediate lifespan ranging from months to a few years; therefore, they have been widely used for the ecological assessment of water quality in an integrative and continuous manner (Park et al, 2007). Fish, which are the longest-lived organisms in aquatic environments as well as being migratory organisms, can be found everywhere in aquatic ecosystems and play a major role in aquatic food-webs as a carrier of energy from lower to higher trophic levels (Beyer, 1996).…”

-This study investigated the relationships of three major aquatic assemblages (diatom, macroinvertebrate, and fish) and environmental variables, including sub-basin, hydrology, land cover, and water quality variables on multiple scales. Samples were collected at 720 sampling sites on the Korean nationwide scale. Geological variables, including altitude and slope, showed a strong positive correlation with proportions of forest in land cover types and cobbles in substrates, while they were negatively correlated with water quality variables, including conductivity and total phosphorus. Considering the concordance of the different assemblages, species richness of fish and macroinvertebrates displayed significant correlation, and diatoms were significantly correlated with fish. However, diatoms did not show significant correlation with macroinvertebrates. Altitude and slope showed significant correlation with all biological variables of the three assemblages. Macroinvertebrates and fish showed positive relations with large substrate sizes. Indices of diatoms and macroinvertebrates well reflected the perturbation of water quality variables. However, fish indices showed a relatively low association with water quality variables, compared with those of diatoms and macroinvertebrates. These patterns were also confirmed by the ordination and prediction of biological indices with environmental variables through the learning process of a self-organizing map as well as random forest. Overall, our study supports the concept of multi-scale habitat filters and functional organization in streams, and is consistent with the recommended use of multiple biological indices with more than one assemblage for the assessment of the biotic integrity of aquatic ecosystems.

“…The SOM produces virtual metrics in a low dimensional network through an unsupervised learning process. SOMs are employed in the classification and ordination of ecological data, such as the evaluation of environmental conditions (Park et al, 2003a;Céréghino and Park, 2009), the ordination of population and community data (Park et al, 2003b(Park et al, , 2007, and the prediction of ecosystem state (Recknagel et al, 2006).…”
