Macrozoobenthos of Basti Damar Stream in Rudraprayag District, Garhwal, Uttarakhand: Diversity and Habitat Analysis

The physical and ecological health of streams is both influenced by riparian vegetation. It helpsto maintain the balance of oxygen, nutrients, and sediments in the environment, as well asproviding habitat and food for micro and macrofauna. The purpose of this study was to add toour understanding of the riparian vegetation of the Sahastradhara stream in Doon Valley. Thestudied riparian zone of the Sahastradhara stream in Dehradun comprises a total of 69 plantspecies belonging to 41 different families. The Asteraceae family, with 13 species, dominatedthe riparian vegetation, followed by Euphorbiaceae (04 species), and Solanaceae (04 Species).

“…Khanda Gad stream has been reported to have 14 different species of water mites (Acari: Hydrachnidia) (Kumar and Dobriyal, 1992;Pesic et al, 2004;2007a-b;Kumar et al, 2007;Bahuguna and Negi, 2021). Periphyton diversity and distribution in relation to stream physicochemical parameters have a significant impact on the occurrence of several aquatic mites (Pesic et al, 2020ab;2022a,b;Baluni et al, 2017Baluni et al, ,2018Baluni et al, ,2020Bahuguna et al, -b, 2020aBaluni 2020;Negi et al, 2021a,b), drifting behaviour of micro and macrozoobenthos (Bahuguna et al, 2019b(Bahuguna et al, , 2020bDobriyal, 2020,2022) and on the diversity of fishes (Rayal et al, 2021 a,b;Bahuguna 2020Bahuguna ,2021Bahuguna and Joshi, 2012;Bahuguna et al, 2010) as well as macrozoobenthos (Rautela, et al, 2006;Bahuguna and Dobriyal, 2018;Kumar and Dobriyal, 1999;Mamgain et al, 2021) Declaration: We also declare that all ethical guidelines have been followed during this work and there is no conflict of interest among authors.…”

Analysis of Riparian Vegetation Diversity at Khanda Gad Stream, Garhwal Himalaya, Uttarakhand, India

et al. 2022

The floral diversity found along water streams and rivers is known as riparian vegetation. Itis a zone of transition between terrestrial and aquatic ecosystems. Riparian vegetation helpsto maintain nutrient balance and energy flow in ecosystems, as well as provides a variety ofresources to aquatic mites and other macroinvertebrates. It also helps to control sediment load inwater bodies, which affects water quality. The purpose of this study was to add new informationabout the status of riparian vegetation in the hill-stream Khanda Gad and to investigate itsimpact on the occurrence of aquatic mites. During the current study, 45 plant species from 31different families were collected and identified. The Rosaceae were identified as the dominantfamily.

“…Numerous authors noted the presence of macro and microzoobenthos along with rich epilithic periphyton and debris standing stock (Bahuguna et al, 2021). The diversity and distribution of periphyton in relation to the physicalchemical characteristics of streams greatly influence the presence of various aquatic mites (Kumar and Dobriyal, 1992;Balodi et al, 2004;Pesic et al, 2020a-b;2022a,b;Baluni et al, 2017Baluni et al, , 2018Baluni et al, , 2020Bahuguna et al, 2019aBahuguna et al, , 2020aBaluni 2020;Negi et al, 2021a,b;Rana et al, 2022), macrozoobenthos (Rautela et al, 2006;Kumar and Dobriyal, 1999;Bahuguna and Dobriyal, 2018;Mamgain et al, 2021), drifting behavior of macrozoobenthos (Bahuguna et al, 2019b(Bahuguna et al, , 2020bBahuguna and Dobriyal, 2020) and on fish diversity (Bahuguna et al, 2010;Bahuguna and Joshi, 2012;Rayal et al, 2021 a, b).…”

Drifting-Density and Diversity of Aquatic Mites in the Spring- Fed Stream Heval from Garhwal Himalaya

et al. 2022

Drift is a major feature in the continuous distribution of macroinvertebrates. In the currentstudy, the density and variety of mites that float in the spring-fed stream Heval are observed andevaluated. During the evaluation period from December 2021 to February 2022, a maximumof 15 species from six families were recorded. The Dobriyal-Bahuguna Drifting Index (DBDI)gives insight into the relationship between the population that is in the environment at a giventime and the population that chooses to drift or is forced to drift. The findings of DBDI revealedthat the maximum drifting value (0.2886) for all mite populations was observed in February inthe spring-fed stream Heval. In contrast, it was at its lowest (0.2513) in December
