“…The physicochemical characteristics of the upstream of the Sampolawa River vary each season (Figure 2). The temperature in the upstream part is relatively low due to the forest's shade of the water body compared to the middle and downstream (Rezende et al 2014;Kahirun et al 2019). In aquatic systems, the quality and quantity of organic matter are important factors that can affect benthic macrofauna communities (Uwadiae 2018).…”

Abstract. Erif, LOM, Djohan TS, Sudarmadji, Yasin A, Sudia LB, Kahirun. 2023. The application of the River Continuum Concept (RCC) on the headwaters of the Sampolawa River in Southeast Sulawesi, Indonesia. Biodiversitas 24: 290-299. Benthic aquatic insect communities in temperate regions have been used as bioindicators of a healthy forest in the stream headwaters.This research analyzes the abundance of benthic insects, the quality of water and nutrient sediment, and the response of the insect community in the Sampolawa River. The samples were collected using stratified random sampling methods with a Surber sampler 30 cm x 30 cm, 5 segmented streams, and 200 m with 4 replication. The results show that 19 species of 5 community feeding groups were found, including collector filters, gatherers, predators, scrapers, and shredders. However, the shredders community is very small, at about 2-4 %. The benthic insect aquatic dominance by collector filter with 29 % reflected that input from terrestrial vegetation is Fine Particulate Organic Matter (FPOM). Therefore, it can be deduced that Sampolawa headwaters do not fit with the prediction of the "River Continuum Concept (RCC)"for a typical headwater since the allochthonous energy supply from riparian vegetation is in the form of fine detritus.

“…Anthropogenic land covers may also favor the best competitor, thereby increasing the abundance of a few organisms (Allan, 2004;Shanafield et al, 2021). Therefore, land covers resulting from different uses may affect stream habitats differently, altering the diversity and functioning of the ecosystem and its organisms (Kahirun et al, 2019;Jankowski et al, 2021). Among aquatic organisms that are sensitive to land use changes, macroinvertebrates are perhaps the main indicators of freshwater ecosystem health (Kahirun et al, 2019;Firmiano et al, 2021).…”

In this way, benthic macroinvertebrate communities are central components of freshwater ecosystems and so the analysis of their diver-sity patterns is an important tool for understanding and conserving aquatic systems (Heino et al, 2015b(Heino et al, , 2018.…”

Knowledge of the frequency and occurrence of macroinvertebrates throughout landscapes may clarify the effects of anthropic impacts on aquatic systems and help guide conservation actions for watersheds. We evaluated macroinvertebrate α and β diversity in streams in four different subtropical phytophysiognomies: highland grasslands with arboreal riparian vegetation, highland grasslands without arboreal riparian vegetation, mixed ombrophilous forest and silviculture. We also evaluated how environmental factors influence α diversity. We sampled macroinvertebrate communities (by Surber sampler), litter input (by nets) and physicochemical variables of the water (by multiparameter and chemical analysis) at 10 sites in riparian zones of a highland system. A total of 2124 individuals were sampled representing 41 taxa, with high α and β diversity in mixed ombrophilous forest. The results indicate that environmental heterogeneity increases food resource availability, as well as macroinvertebrate diversity. Furthermore, the β diversity was found to increase with distance among the unconnected streams. Areas of silviculture had the highest density values among the sampled areas due high organic material stock in the soil. Therefore, higher leaf litter input may decrease the toxicity effect of secondary compounds released by leaf plant decomposition compared to environments with low systemic leaf litter input, such as highland grasslands. The presence of arboreal riparian vegetation drives canopy openness, water temperature, dissolved oxygen, and orthophosphate in streams, which control the frequency and occurrence of benthic macroinvertebrates. Homogeneous systems, as naturally observed in highland grasslands, plus high canopy openness decrease macroinvertebrate richness and density. The naturally low richness of highland grasslands, although with endemic species, may be an important guideline for legislation on anthropic impacts, management, and conservation of streams in this specific subtropical zone.

“…Therefore, we must take proactive measures to preserve natural resources and maintain sustainability. Assessment of river water quality based on macroinvertebrates has advantages over physical and chemical parameters (Kahirun et al 2019). River water quality based on physical and chemical parameters is fluctuating so it must be re-measured periodically ).…”

Abstract. Kahirun, Basrudin, Siwi LO, Indriyani L, Bana S, Sudia LB, Erif LOM, Midi LO, Maulina N, Jamaluddin N. 2023. Used macroinvertebrates as bioindicators to compare water quality from different land uses in Watumokala and Nokambu Rivers, Southeast Sulawesi, Indonesia. Biodiversitas 24: 5693-5708. Macroinvertebrates are animals that live in waters, both on the surface of the water, in riverbeds attached to substrates or mud, and in several biotypes, which are used as bioindicators of water quality due to anthropogenic disturbances that can change land use around rivers. This study aimed to describe the physicochemical parameters and macroinvertebrate community in the Watumokala and Nokambu rivers in Southeast Sulawesi, Indonesia, and to compare the water quality in the two rivers based on ecological index measurements. This study used a survey method at the upstream, middle, and downstream sampling locations for each river with different land use. Data collection on macroinvertebrates and physicochemical parameters was carried out at each station in each river. The data analysis carried out in this study was to calculate the Shannon-Wienner diversity index, species abundance index, uniformity index, Margalef richness index, and the Family Biotic Index (FBI). The results of this study indicated that in the Watumokala River, there were 17 families from 9 macroinvertebrate orders with an abundance of 1852 individuals, more than in the Nokambu River where 14 families were found from 8 orders with an abundance of 904 individuals. There is an influence of land use habitat on macroinvertebrates in the Watumokala and Nokambu Rivers. In the Watumokala River station 1 and station 3 are similar and have a significant correlation with several indicators indicating that the water quality is still good, while at station 2 there is a positive correlation with physicochemical parameters which indicates that the water quality is slightly polluted. Likewise, in the Nokambu River, at station 1 and station 2, there are similarities and significant correlations between physicochemical parameters and macroinvertebrate communities in providing indicators that water quality is still good, while station 3 shows a significant correlation with physicochemical parameters and macroinvertebrates as indicators of water quality polluted. So, the results of this research are useful in efforts to manage land and water in rivers that are experiencing pollution.
