“…Different types of anthropic impacts, such as total or partial removal of riparian vegetation, can cause a decrease in water quality and change in the invertebrate distribution pattern (Roth et al, 1996;Yoshida & Rolla, 2012), based on the sensitivity and tolerance of each taxon to stress factors (Mugnai et al, 2011;Yoshida & Rolla, 2012). Both samplers were effective in the search of those groups.…”

“…Biomonitoring programs use the response of organisms to assess changes in the environment, whether natural or arising from anthropogenic actions (Buss et al, 2003). In these programs, benthic invertebrates are the most tested and used group because they are good indicators of environmental quality and are found in practically all aquatic habitats (Buss et al, 2003;Mugnai et al, 2011;Siegloch et al, 2014;Buss et al, 2015).…”

Aim We compared the effectiveness of two sampling devices, the Surber sampler and the D-frame net, commonly used in the analysis of invertebrate fauna structure in biomonitoring programs. These programs use the response of benthic invertebrates to assess changes in aquatic ecosystems because they respond quickly to spatial and temporal variations. However, the lack of consensus on the best method of sampling the fauna may reduce the quality of these studies. Methods We evaluated both devices in four structurally different reaches of streams, two in places with preserved riparian vegetation and two occurring in places with many anthropic disturbances. We repeated the analysis at the dry season of two consecutive years. Results The two samplers were equally effective in analyzing the benthic fauna and sensitive enough to identify spatial and temporal variation in the structure of this fauna, influenced by the presence or absence of riparian vegetation, by the position of the reach with this vegetation (upstream or downstream of the reach without vegetation) and the characteristics of the substrate. Conclusions The analyzed fauna structure was similar for the two samplers, but we consider the use of Surber more advantageous and effective because it collects a smaller number of individuals, reducing the time of processing and identifying in the laboratory, and allows a better definition of the area sampled.

“…Oligochaeta, especially the family Tubificidae, displace other benthic macroinvertebrates that are intolerant to organic pollution due to their capacity to increase in numbers due to increased organic matter (Schenková & Helešic, 2006). For this reason, they are among the families with high potential as indicators of organic pollution (Martins et al, 2008).…”

Biomonitoring is an approach that uses indicators or sentinel species to assess the health or pollution of an environment, combining diversity based on specific taxonomic groups with the taxa's indicator of pollution into a single index or score. Benthic macroinvertebrates are among the most preferred and valuable indicators of the biotic index. Our study aims to evaluate water quality and ecological status using biotic and diversity indices based on benthic macroinvertebrates. The macroinvertebrate samples used in this study were collected seasonally from 16 stations determined in Karasu Stream. These samples consist of 14,747 specimens belonging to 9 orders and 40 families of Insecta, Malacostraca, Hirudinea and Oligochaeta. In addition, some physicochemical parameters were measured at the stations. The data obtained were analysed using the Turkey‐Biological Monitoring Working Group (TR‐BMWP), Average Score per Taxon (ASPT), Family Biotic Index (FBI), Ephemeroptera, Plecoptera and Trichoptera (EPT) taxon richness index, and Shannon–Wiener, Simpson and Hill's diversity indices. Our results showed that the last six stations of Karasu Stream were under pressure due to various anthropogenic effects. According to biotic indexes, the ecological quality status of the water in the stations was determined to be high or good in the first 10 stations and average, poor or bad in the last 6 stations. The results of our study showed that TR‐BMWP, FBI and EPT indices are more reliable in determining water quality than the ASPT index and reflect the environmental situation better. Since the TR‐BMWP index is adapted to macroinvertebrate taxa distributed in Türkiye, it can be used as a suitable tool for evaluating other rivers' water quality in Türkiye.

Prompt assessment and management actions are required if we are to reduce the current rapid loss of habitat and biodiversity worldwide. Statistically valid quantification of the biota and habitat condition in water bodies are prerequisites for rigorous assessment of aquatic biodiversity and habitat. We assessed the ecological condition of streams in a southeastern Brazilian basin. We quantified the percentage of stream length in good, fair, and poor ecological condition according to benthic macroinvertebrate assemblage. We assessed the risk of finding degraded ecological condition associated with degraded aquatic riparian physical habitat condition, watershed condition, and water quality. We describe field sampling and implementation issues encountered in our survey and discuss design options to remedy them. Survey sample sites were selected using a spatially balanced, stratified random design, which enabled us to put confidence bounds on the ecological condition estimates derived from the stream survey. The benthic condition index indicated that 62 % of stream length in the basin was in poor ecological condition, and 13 % of stream length was in fair condition. The risk of finding degraded biological condition when the riparian vegetation and forests in upstream catchments were degraded was 2.5 and 4 times higher, compared to streams rated as good for the same stressors. We demonstrated that the GRTS statistical sampling method can be used routinely in Brazilian rain forests and other South American regions with similar conditions. This survey establishes an initial baseline for monitoring the condition and trends of streams in the region.
