Benthic Macroinvertebrates Diversity as Bioindicator of Water Quality of Some Rivers in East Kalimantan, Indonesia

Abstract

The objectives of this study were to clarify and evaluate the water quality of a number of rivers in East Kalimantan province of Indonesia. For this purpose, our study successfully utilized the benthic macroinvertebrates diversity as well as physicalchemical parameters of river's water. For instance, based on the values of Average Score per Taxon (ASPT) and the National Sanitation Foundation-Water Quality Index (NSF-WQI), Karang Mumus River was categorized as polluted with Chironomus sp. and Melanoides tuberculata as codominant taxa. In addition, Jembayan River exhibited doubtful or moderate quality containing M. tuberculata and A. parvula as codominant taxa. However, Pampang River was found to be the cleanest river with Odonata and Baetidae families as codominant taxa.

Spatiotemporal dynamics of terrestrial invertebrate assemblages in the riparian zone of the Wewe river, Ashanti region, Ghana

“…The index ranges from 1 to 15. Thus, intact condition class (10)(11)(12)(13)(14)(15): areas dominated by different vegetation strata that cover the full length of the segment, which is linked to natural fluvial forms and slightly fragmented; moderately disturbed condition class (7-9): areas with vegetation cover nearly half of the study zone being disturbed, 1-3 m active channel width and about 10-30% exotic and ruderal species present. Severely disturbed condition class (1-6): areas where 60% of the riparian corridor is reduced by human-led activities, vegetation covering <30% (mainly grasses/herbs and isolated woody species) with channel banks connected to agricultural fields.…”

“…Being a refugium for many invertebrates [ 7 ], fragmentation of riparian zones, following disturbances such as farming practices, grazing, and logging, could potentially reduce their habitats into narrow ranges and consequently affect community structure. Ecologists have used terrestrial invertebrates as indicators of ecological condition or stream biological integrity due to their high sensitivity to disturbances and wide distribution [ 8 , 9 , 10 ]. A study has revealed about 45% reduction in global terrestrial invertebrate population in the current Anthropocene epoch, which could likely cascade onto ecosystem functioning and human well-being [ 11 ].…”

Evaluation of land use impact on river water quality using macroinvertebrates as bioindicator in Lahumoko Watershed, Buton Island, Indonesia

“…The Shannon diversity index (H'), richness index (C), and evenness index (E) are widely used to predict aquatic environmental conditions based on the biological components (Maneechan and Prommi 2015;Patang et al 2018). The higher Shannon diversity index means, the better the quality of water: the value of H' smaller than one indicates high water pollution, between one and three moderate pollutions and greater than four no pollution (Wilhm and Dorris 1968).…”

Preliminary assessment of the deteriorating state of a dam in north-western Nigeria using phytoplankton structural assemblage and environmental factors

“…Resident aquatic biota, including microorganisms, phytoplankton, zooplankton, macroinvertebrates, and fish are widely used to monitor the levels of freshwater pollution worldwide (Arimoro, Ikomi, Nwadukwe, Eruotor, & Edegbene, 2014;Patang, Soegianto, & Hariyanto, 2018). Among aquatic biota used in monitoring freshwater ecosystems, phytoplankton are primary producers, and therefore they constitute the base of aquatic food webs underpinning reservoir ecosystem stability and function (Geider et al, 2001).…”
