“…[42]. Among those that are still present today, most have established self-sustaining populations ( Table 2); even though some occupied a very restricted area, such as the rock bass (Ambloplites rupestris) [49]. Few other alien species are probably not established, such as the rainbow trout Oncorhynchus mykiss or the grass carp Ctenopharyngodon idella.…”

“…Few other alien species are probably not established, such as the rainbow trout Oncorhynchus mykiss or the grass carp Ctenopharyngodon idella. In total, the fish species richness has increased in the past decades [49] and there are today more than 100 species inhabiting France, which belong to 26 families. The two most speciose families are Cyprinidae (n = 40) and Salmonidae (n = 9), whereas 12 are monotypic, among which Gadidae [50].…”

“…Then, new species were deliberately introduced to improve the fish market economy by diversifying the market of native species, for sport fishing, to act as biological control agents of algal blooms in eutrophic ecosystems, or to control mosquitoes [3]. More recently, because of stricter legislation and change in fisheries management practices away from stocking with non-natives [34], the main pathways for alien fish introduction are via either the ornamental trade and subsequent unintentional introduction [6,11] or angling practices, such as for the asp (Aspius aspius), which is one of the three alien species that showed the most spectacular colonization in France during the past decades [49]. Besides, several introductions were accidental (e.g., during stocking events), which is probably the case for species not favored for fishing, such as Pseudorasbora parva, Pachychilon pictum, and pumpkinseed Lepomis gibbosus [49].…”

“…Thereafter, with the control of artificial production, it has become one of the leading species in inland European aquaculture [62] and accounts for more than three-quarters of the French fish production [61]. Yet, rainbow trout is still considered non-established in France [49], and in most European countries, except in few Norwegian drainage basins where only six self-reproducing populations are confirmed by the mid-1990s…”

Introduction of alien species constitutes worldwide one of the major threats to biodiversity, particularly in freshwater ecosystems. In France, the number of alien aquatic plant and animal species has increased exponentially over time in freshwater ecosystems and shows no sign of decreasing. For fish only, more than 40 alien species have been either voluntary or involuntary introduced in the past decades. About two-thirds are still present today and at least 26 are naturalized. As in many European countries, the fish introduction history in France switched from voluntary introduction in the nineteenth century (aquaculture, sport fishing, and management of ecosystems) to unintentional but humanaided introductions (aquarium trade and global ship transport). The negative impacts of alien species on native species and ecosystems are most often unknown in France and needs further studies to develop a functional policy on alien species introductions and the protection of aquatic ecosystems integrity. The information gathered allow discussing the possible reasons explaining whether an alien species is able or not to establish sustainable populations in France and thereafter became invasive, such as gobies recently arrived.

Although ecosystems are increasingly threatened worldwide, the resources available to set up management actions, such as conservation or restoration, remain severely limited. Methods designed to spatially allocate conservation and restoration actions while maximizing their ecological benefits are urgently needed. Whereas conservation planning methods have been extensively developed in past decades, improvements in restoration planning are still needed to build efficient management tools. This methodological gap may be explained by the difficulties encountered when estimating non‐disturbed ecological conditions (i.e. reference conditions) which are usually required to compare past and present ecosystem states. Here, the species composition of stream fish assemblages in 607 river stretches of the Pas‐de‐Calais department in the north of France was predicted using species distribution models. Present occurrence was predicted according to four environmental variables, including two related to human‐induced disturbances (i.e. proportion of river stretch length affected by hydraulic works and local geomorphological alterations). The fish assemblages potentially present in the absence of such disturbances were then predicted using hindcasting modelling which involves artificially setting to zero the values of the disturbance variables in the models. A framework based on a multi‐faceted approach of diversity was applied to the present‐day fish assemblages and those predicted under the two non‐disturbed scenarios (i.e. restoration scenarios) to assess their suitability for management. While the theoretical restoration of the natural flow regimes was likely to result in few changes in fish assemblage composition and consequently in their multi‐faceted diversity, the restoration of natural geomorphological characteristics was predicted to reduce the taxonomic diversity but increase the functional diversity, the natural heritage importance and the socio‐economic value of the fish assemblages. This study provides environmental decision‐makers with a tool to identify precisely and simultaneously the conservation and restoration actions that have to be undertaken as a priority, by comparing the present and non‐disturbed multi‐faceted diversity indices.

Variability of functional traits and their syndromes in a freshwater fish species (Phoxinus phoxinus): The role of adaptive and nonadaptive processes

Functional traits can covary to form “functional syndromes.” Describing and understanding functional syndromes is an important prerequisite for predicting the effects of organisms on ecosystem functioning. At the intraspecific level, functional syndromes have recently been described, but very little is known about their variability among populations and—if they vary—what the ecological and evolutionary drivers of this variation are. Here, we quantified and compared the variability in four functional traits (body mass, metabolic rate, excretion rate, and boldness), their covariations and the subsequent syndromes among thirteen populations of a common freshwater fish (the European minnow, Phoxinus phoxinus ). We then tested whether functional traits and their covariations, as well as the subsequent syndromes, were underpinned by the phylogenetic relatedness among populations (historical effects) or the local environment (i.e., temperature and predation pressure), and whether adaptive (selection or plasticity) or nonadaptive (genetic drift) processes sustained among‐population variability. We found substantial among‐population variability in functional traits and trait covariations, and in the emerging syndromes. We further found that adaptive mechanisms (plasticity and/or selection) related to water temperature and predation pressure modulated the covariation between body mass and metabolic rate. Other trait covariations were more likely driven by genetic drift, suggesting that nonadaptive processes can also lead to substantial differences in trait covariations among populations. Overall, we concluded that functional syndromes are population‐specific, and that both adaptive and nonadaptive processes are shaping functional traits. Given the pivotal role of functional traits, differences in functional syndromes within species provide interesting perspectives regarding the role of intraspecific diversity for ecosystem functioning.
