“…Flow velocity was associated with 11 taxa (43%), with a positive effect on Rhithrogena spp., known as a genus of rheophilic crawlers (Dolédec et al, 2007;Tachet et al, 2010). This result is consistent with the study by Forcellini et al (2022) Concerning hydrology, summer flow was selected in 43% of models with negative associations with eight taxa from various orders (e.g. Baetis spp., Protonemura spp., Ceratopogoninae, Oligochaeta).…”

Ongoing hydrological alterations due to climate change and anthropogenic uses of water have major implications for freshwater biodiversity. Quantifying the relative effects of environmental variables on macroinvertebrates is required to predict biological responses to hydrological alterations. To date, no study simultaneously examined the effects of physico‐chemistry, hydraulics, and hydrology on the distribution of alpine macroinvertebrate communities and taxa. In this study, we aimed to quantify the relative correlation between these environmental variables and macroinvertebrate community composition and structure. We sampled macroinvertebrates at 66 stream sites located in three catchments in the French Alps. We characterised the proximate habitat at each site using 11 variables describing measured physico‐chemistry and hydraulics, and simulation‐based hydrology. We described relationships between community structure and the environment using a co‐inertia analysis and modelled individual taxa abundance with generalised linear mixed models. The co‐inertia revealed a significant co‐structure between the environmental and macroinvertebrate matrices. Glacier‐influenced sites with high turbidity and summer flow exhibited similar community composition with low total abundance. Sources at high altitude and sites with low glacial influence, exhibiting high summer flow and flow velocity, were dominated by Diamesinae, Rhithrogena spp., Dictyogenus spp., and Baetis alpinus. Streams fed by rainfall/snowmelt and valley sources, associated with higher temperature, conductivity, and monthly discharge variability were characterised by higher richness and abundances. Models indicated that the three types of proximate habitat variables significantly contributed to the macroinvertebrate distribution. Turbidity was strongly negatively associated with macroinvertebrate abundances. Increasing flow velocity and summer flow had significant (mainly negative) effect in 43% of models. The co‐structure between communities and proximate habitat variables was shared by the three catchments. For most individual taxa, catchment identity did not influence abundance models and cross‐validations indicated transferable effects of proximate habitat variables among alpine catchments. Our results can be used to infer responses of alpine macroinvertebrates to multivariate environmental changes. Understanding the relationships between macroinvertebrates and environmental variables help to predict how communities and taxa will be affected by habitat alterations due to ongoing hydrological changes and resulting physico‐chemical conditions.

“…We speculate that this phenomenon shows that the response pattern of entire macroinvertebrate assemblages was essentially a weighted combination of each taxon (Wright, 1995), and was modified by individual taxon as well as inter‐taxa interactions within assemblages (Feng et al., 2017). To be specific, when the entire assemblages were examined, the presence of some taxa was favored by flow ( Brachycentrus and Limnophila in this study) while others ( Polypedilum in this study) were not, thus compensation among all the taxa yielded a final unimodal response (Forcellini et al., 2020). Therefore, the “optimal” flow obtained in this study could not yield a flow condition most suitable for all the taxa within assemblages.…”

“…Variation in macroinvertebrate assemblages in a river could be largely explained by the patch‐scale flow condition (Fornaroli et al., 2019). Individual species often show a significant relationship with variables associated to flow (e.g., shear stress, average velocity, Froude number; Dolédec et al., 2007; Shearer et al., 2015), and flow preferences may differ among species, as indicated by differences in species abundance (Forcellini et al., 2020). In addition to changes in abundance, macroinvertebrates commonly display morphological and biological adaptations to flow.…”

“…However, it is still expected that the morphological, functional and trophic structures of biotic assemblages may be altered when the variations in flow exceed a certain threshold and become "extreme" (Bêche et al, 2009;Gibbins et al, 2007). The influence of flow has been studied in a wide range of biota, from microorganisms to vertebrates, but mostly on macroinvertebrates (e.g., Forcellini et al, 2020;Muñoz-Mas et al, 2019;Worrall et al, 2014;Zhang et al, 2018) and fishes (e.g., Belmar et al, 2018;Hitt et al, 2020;Irvine et al, 2009;Tonkin et al, 2017). In general, flow affects biotic assemblages through alterations of the hydrodynamics (e.g., stream power, water level, near-bed shear stress, temporal flow fluctuation, turbulence; Hart & Finelli, 1999;Jowett, 2003;Wedderburn et al, 2012;Blanckaert et al, 2013;Zhou et al, 2017), sediment movement processes (e.g., substrate composition, suspended load, channel bed stability; Boubée et al, 1997;Duan et al, 2009;Zhao et al, 2015), physicochemical environmental variables (e.g., water temperature, dissolved oxygen, salinity; Korven & Wilcox, 1964;Wilcock et al, 1998;Lowney, 2000), and transportation of autochthonous and allochthonous substances (e.g., organic detritus, nutrients, pollutants; Maazouzi et al, 2013;Mathooko et al, 2001;Xu et al, 2014).…”

The Qinghai-Tibet Plateau (QTP), also known as the Third Pole Region, is the largest high-altitude land mass on Earth. The region holds the most freshwater, mainly in the form of glaciers, outside the polar ice caps (Morton, 2011). The QTP is of critical ecological importance, possessing diverse biomes (alpine tundra, montane forest, subtropical dry forest, and tropical montane rainforest; Ni & Herzschuh, 2011), and encompasses several biodiversity hotspots (e.g., in the mountainous areas of Central Asia, Himalayas, Indo-Burma, and Hengduan range; Tang et al., 2006). The river and stream biota in the QTP are highly specialized owing to the unique conditions, making them especially vulnerable to external disturbances (Favre et al., 2015;Xu et al., 2018;Yao et al., 2012). Environmental conditions that have been intensively modified by anthropogenic activities and climate warming during recent decades include instream flows, jeopardizing the services provided by alpine rivers with healthy ecosystems (Poff et al., 1997;Wenger et al., 2011).

“…Another feature is that many normal fishways do not have riverbed material at the bottom. However, riverbed materials are essential for bottom-dwelling fish species and other benthic organisms [7,[42][43][44][45][46]. Thus, installing other types of fishways with gentle slopes and riverbed materials is crucial for preserving the biodiversity of the river channel [3,10].…”

The migration of fish is influenced by the unique environmental characteristics of the destination and migratory habitat preferences. There are three fishways in Miyanaka Intake Dam. The rock-ramp fishway was newly established in 2012, creating an environment with different flow velocities and water depths. The purpose of this study was to investigate the effectiveness of the new rock-ramp fishway for native fish through two surveys. In the first survey, traps were installed during the survey period in all three fishways and all fish were caught. The run-up environment was quantified by measuring the flow velocity. In the second survey, fish were caught by spectrum methods upstream and downstream from the dam. It was found that bottom-dwelling fish and swimming fish not bound to the bottom with low migration abilities used the rock-ramp fishway for migration and as a habitat. After the new rock-ramp fishway was built, catches increased upstream from the dam. Further, the rock-ramp fishway is a potential habitat for certain species, such as Cottus pollux. As this is the first study to demonstrate the effectiveness of rock-ramp fishways, the research results are expected to be valuable to fishery managers and those planning river engineering projects.
