“…Here, the abundance of some species (e.g., Gammarus ) increased while others (i.e., Baetis and Dipterans) declined. Because of its ability to enter into the sediment for refuge (Dole‐Olivier, Marmonier, & Beffy, ), Gammarus has an advantage, with respect to other species, in tolerating rapid and periodic changes in the river flow due to hydropeaking (Mondy, Muñoz, & Dolédec, ).…”

In this study, the combined effects of hydrological and chemical stressors on benthic macroinvertebrates were evaluated in order to explore the response of the biological community to multiple stressors. The Adige River, located in the south‐eastern Alps, was selected as a case study because representative of the situation of a large river in which the variety of stressors present in the Alpine region act simultaneously. As expected, streamflow showed a seasonal pattern, with high flows in the spring–summer period; however, locally, the natural hydrological regime was altered by the presence of hydropower systems, which chiefly affected low flows. Multivariate analysis showed seasonal and spatial patterns in both chemical and hydrological parameters with a clear gradient in the concentration of nitrate, personal care, and pharmaceutical products moving from headwaters to the main stem of the river. The macroinvertebrate community composition was significantly different in summer and winter and between up and downstream sites. Streamflow alteration chiefly due to water use by hydropower affected community composition but not richness or diversity. Gammarus sp., Hirudinea, and Psychomyia sp., were positively correlated with flow variability, increasing their densities in the sites with higher streamflow variability because of hydropeaking. The results obtained in this study show that the composition of the macroinvertebrate community responded to seasonality and to changes in the main stressors along the river and highlights the importance of the spatial and temporal variability of stressors in this Alpine river. Taking into account, this variability will help the decision‐making process for improving basin management.

“…Trait-based approaches have recently received increasing attention due to their potential ability to improve the predictions in community ecology (McGill et al 2006). This potential is based on the hypothesis that the environment acts as a filter on organisms through their traits (Southwood 1977), a hypothesis that recently received increasing support (Jung et al 2010, Mondy andUsseglio-Polatera 2014), e.g., also in the context of multiple stressors (Mondy et al 2016). This has led to the development of promising approaches to predict key features of communities (Shipley et al 2006, Laughlin et al 2012.…”

Predicting the composition and dynamics of communities is a challenging but useful task to efficiently support ecosystem management. Community ecology has developed a number of promising theories, including food webs, metabolic theory, ecological stoichiometry, and environmental filtering. Their joint implementation in a mechanistic modeling framework should help us to bring community ecology to a new level by improving its predictive abilities. One of the challenges lies in the proper consideration of model uncertainty. In this paper, we contribute to this challenging task by modeling the temporal dynamics of macroinvertebrate communities in a stream subjected to hydropeaking in Switzerland. To this end, we extended the mechanistic model Streambugs regarding flood-induced drift processes and the use of trait information to define performance filters. Model predictions without any calibration were in the right order of magnitude but did not reflect the dynamics of most of the invertebrate taxa well. Bayesian inference drastically improved the model fit. It revealed that a large share of total model output uncertainty can be attributed to observation errors, which exceeded model parameter uncertainty. Observed and simulated community-aggregated traits helped to identify and understand model deficits. The combination of different ecological theories and trait information in a single mechanistic modeling framework combined with Bayesian inference can thus help to predict responses of communities to environmental changes, which can support ecosystem management.

“…The Ebro is the largest catchment in Spain, with a drainage area of 85 550 km 2 (Sabater, Muñoz, Feio, Romaní, & Graça, ). This catchment is especially interesting because it has high environmental heterogeneity (Bejarano, Marchamalo, de Jalón, & del Tánago, ; López‐Moreno et al, ), it harbours several water‐related social conflicts (Garrido, Martínez‐Santos, & Llamas, ; Milano et al, ; Tàbara & Ilhan, ), it is highly populated and intensively cultivated (Martín, Arias, & Corbí, ; Mondy, Muñoz, & Dolédec, ), and it has centralized and accessible data (Ebro Hydrographic Confederation, ). The main objectives of the study were: (i) to establish the conservation criteria that RPAs should meet through a public participation process involving policymakers, stakeholders, scientists, and the general public; (ii) to incorporate these conservation criteria into the design of RPAs following a systematic conservation approach; (iii) to obtain a network of RPAs fitting these criteria; (iv) to assess the performance of the proposed approach by comparing the conservation efficiency of the resulting network of RPAs and the present network of RPAs implemented by Spanish legislation; and (v) to validate the resulting network of RPAs through the public participation process.…”

Freshwater ecosystems generally lack adequate protection. In this regard, defining clear and objective conservation criteria through public participation is extremely important, as it can greatly enhance the feasibility of the conservation plans by building credibility, salience, and legitimacy. This article presents an exercise of systematic freshwater conservation planning informed and validated by public participation using river protected areas (RPAs) in the Ebro catchment, Spain, as a case study. A public participation process was performed to define the conservation criteria that RPAs should meet, resulting in a detailed list of conservation features and constraints that were poorly covered by the present network of RPAs in Spain. The present network of RPAs failed to adequately protect aquatic biodiversity, as 48% of the taxa did not meet the conservation target, including seven species of vulnerable invertebrates and three of vulnerable fish. marxan was used to identify a minimum set of additional areas that would help to meet the conservation target by adequately representing all conservation features and by increasing the efficiency of the network of protected areas. When marxan was run without restrictions, none of the present RPAs was selected, suggesting that the current network of RPAs is not efficiently meeting the conservation demands expressed through public participation. Overall, this study shows that combining public participation and systematic conservation planning could result in more efficient and enhanced protection of freshwater ecosystems by integrating a wide variety of conservation preferences into the design of RPAs. Also, according to the results, having detailed and updated information on the distribution of invasive and endangered species, as well as increasing the frequency and spatial extension of ecological monitoring, are key to meeting the public demands of enhanced freshwater biodiversity protection and the preservation of sites with high ecological value.
