“…Simuliade was dominant in Oak forest at S1 while Limnephilidae was dominant in Pine-Oak forest at S2 (Table 1). Nautiyal et al (2015) also observed similar pattern in the streams/rivers of Uttarakhand Himalaya. Corkum (1992) and Sivaramakrishnan (2005) also reported the impact of forest type on assemblage pattern.…”

“…Agriculture is both extensive and intensive in this lower stretch of the stream and anthropogenic influences hence become a prominent factor because of fertilizer and other inputs. The impact of agriculture and habitation was also observed on the distribution of benthic macroinvertebrate fauna in Himalayan rivers Nautiyal et al 2015) and central Indian rivers (Mishra & Nautiyal 2013a). Vannote et al (1980) suggested that the longitudinal or continuum models predict that invertebrate assemblages will change along the length of rivers as evident in the present study.…”

“…The share of Simulidae decreased from S1 to S5, while Chironomidae increased from S1 to S5. Trichopterans were dominant in the headwater section of the Garhwal Himalayan spring-fed streams (Nautiyal et al 2015) and in headwater zone of Vindhyan spring-fed river Paisuni (Mishra & Nautiyal 2011). In the spring-fed Himalayan streams, Ephemeroptera was dominant taxon in the Khanda Gad (Kumar 1991) and the Gaula in the Kumaun region (Sunder 1997).…”

Benthic macroinvertebrates play important ecosystem roles in the cycling and outflow of nutrients. The benthos transforms organic detritus from sedimentary storage into dissolved nutrients that can be mixed into overlying waters and used by rooted plants (macrophytes) and algae (phytoplankton) to enhance primary productivity. This study examined the distribution pattern of benthic macroinvertebrates in a lesser Himalayan foothill stream from the headwaters (2,200m) to mouth (375m). Five stations (S1 to S5) were established along the 43-km course of the stream. Samples were collected at bi-monthly intervals from January to December 2009. The total density of the benthic macroinvertebrate community increased with decreasing altitude and differed significantly among stations. Dominant orders were Diptera at S1 (Simulidae, 27%) & S5 (Chironomidae 24%), Trichoptera at S2 (Limnephilidae 16%) & S3 (Hydropsychidae 9.9%), and Ephemeroptera (Heptageniidae 9.2%) at S4. Principal component analysis revealed that the characteristic taxa were Simulidae at S1, Limnephildae at S2, Hydropsychiidae, Rhyacophilidae, Tipulidae, Perlodidae, Dryopidae & Notonectidae at S3, Heptageniidae at S4, and Chironomidae, Siphlonuridae, & Agrionidae at S5. Cluster analysis showed one large cluster comprising S1 and S2 as sub-groups with resemblance to S3-S4, and S5 as an outlier. The similarity between the stations S3-S4 was attributed to similar land-use pattern (agriculture) and stream order (II Order), while S1 and S2 were slightly similar due to partial similar forest type (oak forest at S1, pine-oak forest at S2) and stream order. At S5, however, the considerable change in forest type (mixed forest) land-use and stream order (III Order) caused S5 as an outlier in cluster. The variations in the abundant and characteristics taxon at different stations were attributed to change in substratum and land-use patterns.

“…Similarly, the taxa Heptageniidae was persist in most of the assemblages among the stations of Rimbi Khola and tributaries, was attributed to decline of water depth, favour more growth of bottom flora. Trichoptera were abundant in the streams of Mandakini basin in west Himalaya (Nautiyal et al 2015).…”

“…The study of structural composition of benthic macroinvertebrate fauna is governed with various physico-chemical factors such as water quality, sediments quality and biological factors i.e., competition and predation. In view of above global studies, various Indian studies have been conducted in the rivers and streams of different geographical regions like Himalaya (Nautiyal et al 2015, Semwal and Mishra 2019, Mishra and Prasad 2020, the central Highlands , Mishra and Nautiyal 2016 and in the Western Ghat (Dinakaran and Anbalagan 2010, Though many studies have been Santosh et al 2014). performed in the lesser Himalayan region, but very sparse study is available in the rivers of north east Himalaya and especially in the rivers proposed for hydroelectric project.…”

A taxonomic and functional feeding group study of benthic macroinvertebrate fauna was conducted in the headwater streams/Kholas of eastern Himalaya Rimbi Khola and its tributaries (Nambu Khola, Limbuni Khola and Lingsur Khola). Samples were viz. collected twice in a year during January and February 2017. Standard methods were adopted for the samples collection and identification of benthic macroinvertebrate fauna. The density ranged from 264 to 792 indiv.m among Rimbi Khola and tributaries. Seventeen taxa were -2 recorded with highest taxonomic richness in Rimbi Khola compare to the tributaries. Leptoceridae was most abundant taxa in all streams/Kholas followed by Hydropsychidae, Leptophlebidae and Baetidae. CCA identified discharge, current velocity and substratum as most important factors in streams/Kholas, while different characteristics taxa were determined by PCA. These variations in environmental variables and characteristics taxa were attributed to proximate factors in each river. However, trophic characterization indicated that all the streams/Kholas were dominated by shredders. Collectors were second most abundant trophic group in the Rimbi, Limbuni and Lingsur Khola, while scraper in Nambu Khola. Nambu Khola was different from rest of the streams due to variation in dominant trophic groups, because of open stream system and high periphytonic growth.
