“…Furthermore, the decreased variability and frequency of low‐flow events observed in our climate models for both central European catchments, that is, less stress on the species in that respect, resulted in increasing abundances of both species and assemblages of stream macroinvertebrates. However, increasing frequencies of low‐flow events, and hence, decreasing species diversity were reported in other regions (Brooks & Haeusler, ; Chessman, , ; Dewson et al., ; Leigh & Datry, ). This reveals the importance of spatial scale of climate‐change studies and regional differences in the type of responses.…”

Global change has the potential to affect river flow conditions which are fundamental determinants of physical habitats. Predictions of the effects of flow alterations on aquatic biota have mostly been assessed based on species ecological traits (e.g., current preferences), which are difficult to link to quantitative discharge data. Alternatively, we used empirically derived predictive relationships for species’ response to flow to assess the effect of flow alterations due to climate change in two contrasting central European river catchments. Predictive relationships were set up for 294 individual species based on (1) abundance data from 223 sampling sites in the Kinzig lower‐mountainous catchment and 67 sites in the Treene lowland catchment, and (2) flow conditions at these sites described by five flow metrics quantifying the duration, frequency, magnitude, timing and rate of flow events using present‐day gauging data. Species’ abundances were predicted for three periods: (1) baseline (1998–2017), (2) horizon 2050 (2046–2065) and (3) horizon 2090 (2080–2099) based on these empirical relationships and using high‐resolution modeled discharge data for the present and future climate conditions. We compared the differences in predicted abundances among periods for individual species at each site, where the percent change served as a proxy to assess the potential species responses to flow alterations. Climate change was predicted to most strongly affect the low‐flow conditions, leading to decreased abundances of species up to −42%. Finally combining the response of all species over all metrics indicated increasing overall species assemblage responses in 98% of the studied river reaches in both projected horizons and were significantly larger in the lower‐mountainous Kinzig compared to the lowland Treene catchment. Such quantitative analyses of freshwater taxa responses to flow alterations provide valuable tools for predicting potential climate‐change impacts on species abundances and can be applied to any stressor, species, or region.

“…For example, reach-scale hydrological characteristics are highly predictive of the functional trait composition (i.e. life history strategy, functional feeding group and mobility) of macroinvertebrate communities (Brooks & Haeusler, 2016;Richards, Haro, Johnson, & Host, 1997). In addition, Statzner and Bêche (2010) demonstrated the utility of traits such as body size, feeding group, dispersal mode and reproductive strategy for disentangling the responses of macroinvertebrates to multiple environmental stressors.…”

Environmental flow assessments are becoming increasingly central to ecologically‐sustainable river management. Rigorous evaluations of flow–ecology relationships serve a vital role in guiding these assessments to meet targeted ecosystem objectives. However, limited resources and widespread environmental change are outpacing the ability to gain knowledge of species’ flow responses and assess environmental needs for rivers individually. Successfully transferring flow–ecology relationships across space and time would facilitate regional‐scale environmental flow assessments, yet the necessary contexts for such success remains a knowledge gap. Here, we leverage long‐term, multi‐species datasets across multiple river basins in southwestern United States as a case study to explore whether relationships between species abundances and hydrological conditions are transferable across space and time. Additionally, we evaluate the potential for ecological guilds based on fluvial dependence and life‐history strategies to facilitate the transfer of flow–ecology knowledge across taxonomic boundaries. Species varied in the spatial transferability of their flow–ecology relationships. Spatial transferability was similar when comparing a species’ flow–ecology relationships within a river basin versus across different river basins, although transferability was considerably greater across free‐flowing rivers compared to regulated rivers. Species’ flow–ecology relationships transferred through time just as well as across space. Ecological guilds defined according to fluvial dependence and life‐history strategies offered just as much potential for transferring flow–ecology knowledge among species as transferring within species across space or time. Our study provides insights into transferring flow–ecology knowledge to support effective, regional‐scale environmental flows. Further research into developing transferable flow–ecology relationships for a wide range of environmental predictors and biological responses across different spatial scales and flow regimes will enable us to keep pace with the increasing demand for science to inform sustainable river management.

“…• Both intolerant and tolerant macroinvertebrates can persist in streams with diminished high flows if they possess traits that allow them to adapt to their environment, such as the ability to find refuge in both higher and lower velocity patches or temporarily leave the aquatic environment (Brooks and others, 2011;Brooks and Haeusler, 2016;Carlisle and others, 2010). However, alterations in the natural highflow variability, magnitude, and duration can substantially affect the most sensitive species of macroinvertebrates that are less resilient others, 2010, 2014).…”
