“…Since the pioneering work of Karr (1981), fish assemblages have often been used to assess the biological integrity of different water body types Debenay et al, 2003;Oberdorff et al, 2011). However, even if some preliminary indices have been specifically proposed for reservoirs (Blabolil et al, 2016;Launois, Veslot, Irz, & Argillier, 2011;McDonough & Hickman, 1999), such bioindicators are rarely studied in the literature.

“…Non-native introduced species are often large predators such as pikeperch (Sander lucioperca L. 1758) that disturb the structure and dynamics of natural communities (Blanchet et al, 2010;Cucherousset & Olden, 2011;Eby, Roach, Crowder, & Stanford, 2006;Irz, Argillier, & Proteau, 2004). Hence, we can expect (i) a relationship between these non-native species and the functional structure of the whole communities (Mercado-Silva et al, 2009) and (ii) that they interact with eutrophication, which has already been demonstrated to be an important stressor (Blabolil et al, 2016;Launois et al, 2011). As a consequence, these species appear only in some systems and only sporadically.…”

Biological indicators are frequently used to assess the effects of anthropogenic stressors on freshwater ecosystems. The structure of fish communities and their response to stressors have been commonly described by taxonomic richness, diversity and evenness. More recently, functional structure of communities has also been suggested to be a reliable indicator of disturbance. This article aimed at testing whether taxonomic and functional diversity metrics can provide comparable or complementary information on the response of fish communities to eutrophication and abundance of nonnative species in reservoirs. Comparison of the responses of taxonomic and functional diversities to biogeography, habitat and stressors was made in 112 French reservoirs.Widely observed effects of biogeographic and habitat variables on taxonomic and functional diversities were identified. Taxonomic and functional richness metrics notably increased with lake area and temperature respectively. Taxonomic diversity metrics did not respond to any stressor, while all functional diversity metrics were found to be impacted by non-native species. Eutrophication was further found to decrease the impact of non-native species on two functional diversity metrics: evenness and divergence. Our study therefore reveals that functional metrics are more sensitive than taxonomic metrics to anthropogenic stressors in the studied reservoirs. Still, the multiple linear regressions tested had overall low explanatory power. Further refinements will thus be needed to use this type of metrics in an impact assessment scheme.

“…C'est en particulier le cas en France (Launois et al, 2011 ;Mondy et al, 2012 ;Pont et al, 2006). Par exemple, l'omnivorie est utilisée comme un indicateur de dégradation, alors que la spécialisation dans les habitats de reproduction rend compte d'une altération physique faible du milieu.…”

À l'interface entre politiques de l'environnement et connaissances scientifiques écologiques, la directive cadre européenne sur l'eau (DCE) est un cas exemplaire sous de multiples aspects : une inscription claire dans le New Public Management (NPM) qui envahit nos appareils d'État, une traduction du « bon état écologique » en termes d'indicateurs mesurant l'éloignement à des conditions de référence par ailleurs objets de débat dans la recherche écologique, une opportunité pour définir et appliquer des itinéraires de restauration. Le travail à deux voix d'une sociologue et d'un écologue produit ici une analyse fine des conditions d'émergence et de mise en oeuvre de la DCE tout en identifiant les contours de futurs débats (restauration, appropriation citoyenne) au-delà même du terme prévu de la directive (en 2027). La RédactionRésumé -La directive cadre européenne sur l'eau (DCE) 1 impose une nouvelle forme de gestion des milieux aquatiques et la notion de conditions de référence est un point-clé pour la mise en oeuvre de l'évaluation (mesurée comme un écart à cette référence) et pour définir les objectifs de restauration. Cependant, de nombreuses critiques se sont élevées contre ce concept. Le contexte de « changement global 2 » ne fait que renforcer cette tendance. Dans cet article, coécrit par un écologue et une sociopolitiste, nous revenons sur la construction sociale et scientifique de cette notion, des indicateurs qui en découlent et de leur agrégation dans la DCE. En nous focalisant sur son application aux cours d'eau, nous expliquons son origine, son succès, ses limites et les questions que pose son institutionnalisation. Cela nous conduit à nous interroger sur l'avenir de cette politique, en particulier du point de vue de la restauration. Abstract -The reference conditions in the EU Water Framework Directive confronted with the dynamics of hydrosystems and their uses.The reference conditions are a key concept of the European Water Framework Directive (WFD). This directive holds that the ecological status of a particular water body shall be assessed by quantifying the deviation from the typical reference conditions which refer to a stable state of an ecosystem in the absence of significant human disturbance. This concept is subject to criticism from several authors, all the more since global change will deeply modify the functioning of aquatic ecosystems and their associated biocenosis, whatever the impacts of human activities at local scale. In this paper, an ecologist and a sociologist reconsider the social and scientific construction of the reference conditions concept and associated rules ("one out -all out"). We explain its origin, success and limits, as well as the questions it raises. We point out aspects not considered in this concept and why it challenges the WFD implementation and future management of rivers.

“…Changes throughout the world are forcing inland fisheries managers to seek new approaches to cope with current and future climates and ecosystem and social challenges (Arlinghaus, Lorenzen, Johnson, Cooke & Cowx, ; Cooke, Arlinghaus, Johnson & Cowx, ; Hunt et al., ). Reservoirs are relatively novel, artificial and heavily modified water bodies with many characteristics and functions that are not comparable to natural lakes and might require different approaches and solutions (Blabolil et al., ; Launois, Veslot, Irz & Argillier, ). The dissimilarity between reservoirs and lakes goes beyond differences in fish fauna development (Kubečka, vs Colby, Spangler, Hurley & McCombie, , respectively) or hydromorphological characteristics (Blabolil et al., ).…”

The Pilica River has warmed at a rate of 0.06°C per year since 1969, threatening the ecological services provided by the Sulejów Reservoir. Gillnet sampling revealed that the reservoir is inhabited by a cyprinid‐dominated fish assemblage with roach, Rutilus rutilus (L.) (42% of the total biomass), the dominant species. However, the interest of the anglers was primarily focused on common bream, Abramis brama (L.) (almost 65% of the catch), as revealed by the catch statistics (2004–2014). No direct evidence was found that the temperature increase had an influence on the recreational fishery or fish assemblage structure. On the other hand, changes in the fish assemblage that were reflected in angler catch composition were observed. A decrease in the catch of common bream in gillnets was accompanied by a shift in angler choices towards roach and other fish species. The sustainability of recreational fisheries is more likely to be influenced by changes in the economic status of society, water quality (toxic cyanobacteria blooms) and water management practices in Poland. The question arises about which species will dominate in the impoundment in the future if the warming trend continues and common carp, Cyprinus carpio L., stocking is maintained.
