“…Crawford et al ., ; Kadye & Booth, ). Likewise, the introduction of planktivorous fish causes the rapid elimination of large‐bodied zooplankton and their replacement by small‐bodied taxa that may not be reflected in diversity metrics (Ordóñez et al ., ). Furthermore, because of the strong trophic links established in aquatic communities, the impacts associated to the introduction of invasive species extend beyond simple changes in the abundance of particular functional groups, but can threat species interaction at the community level (Sanders et al ., ).…”

“…In contrast, changes in either primary producers or the input of limiting nutrients by invasive species affect the total energy available to the ecosystem, with ‘bottom‐up’ control propagating changes up the trophic ladder (Heath et al ., ). For example, the introduction of zooplanktivorous fish ( Rutilus rutilus and Alburnus alburnus ) into Spanish reservoirs caused a strong decrease in the abundance and richness of large‐bodied zooplankton, which in turn released phytoplankton from its grazing pressure (Ordóñez et al ., ). As opposed to predators, filter feeders like the zebra mussel ( Dreissena polymorpha ) are able to considerably reduce the abundance of phytoplankton (and also small zooplankton), with foreseeable negative consequences upon higher trophic levels (Ward & Ricciardi, ).…”

The introduction of invasive species, which often differ functionally from the components of the recipient community, generates ecological impacts that propagate along the food web. This review aims to determine how consistent the impacts of aquatic invasions are across taxa and habitats. To that end, we present a global meta-analysis from 151 publications (733 cases), covering a wide range of invaders (primary producers, filter collectors, omnivores and predators), resident aquatic community components (macrophytes, phytoplankton, zooplankton, benthic invertebrates and fish) and habitats (rivers, lakes and estuaries). Our synthesis suggests a strong negative influence of invasive species on the abundance of aquatic communities, particularly macrophytes, zooplankton and fish. In contrast, there was no general evidence for a decrease in species diversity in invaded habitats, suggesting a time lag between rapid abundance changes and local extinctions. Invaded habitats showed increased water turbidity, nitrogen and organic matter concentration, which are related to the capacity of invaders to transform habitats and increase eutrophication. The expansion of invasive macrophytes caused the largest decrease in fish abundance, the filtering activity of filter collectors depleted planktonic communities, omnivores (including both facultative and obligate herbivores) were responsible for the greatest decline in macrophyte abundance, and benthic invertebrates were most negatively affected by the introduction of new predators. These impacts were relatively consistent across habitats and experimental approaches. Based on our results, we propose a framework of positive and negative links between invasive species at four trophic positions and the five different components of recipient communities. This framework incorporates both direct biotic interactions (predation, competition, grazing) and indirect changes to the water physicochemical conditions mediated by invaders (habitat alteration). Considering the strong trophic links that characterize aquatic ecosystems, this framework is relevant to anticipate the far-reaching consequences of biological invasions on the structure and functionality of aquatic ecosystems.

“…), channel catfish Ictalurus punctatus (Rafinesque), black bullhead Ameiurus melas (Rafinesque), goldfish] may be similar but have not been studied in this region (Braig & Johnson 2003; Rowe 2007). However, several studies have shown that zooplanktivorous NNFFs such as silver carp Hypophthalmichthys molitrix (Val), rudd Scardinius erythropthalmus (L.) and bleak Alburnus alburnus (L.) have dramatically altered zooplankton biomass, structure and dynamics in Israel (Spataru & Gophen 1985) and Spain (Ordóñez et al. 2010).…”

Non‐native fishes are often blamed for exerting adverse ecological impacts on native fishes, but the evidence is circumstantial and the true impacts remain largely unknown. This dilemma is particularly acute for freshwater ecosystems of the Mediterranean Region, where a high level of endemism (a biodiversity hotspot) makes native fish extinctions much more likely because of their small natural ranges. The aim of this paper is to review non‐native fish impacts, from genes to ecosystem level, in the fresh waters of the Mediterranean Region and identify gaps in knowledge that currently hamper effective conservation and management of native species and ecosystems. Most studies reviewed reported potential impacts rather than realised impact mechanisms, and these were conducted predominantly in the European part of the Mediterranean Region. No studies of realised impacts were found for three of the 15 most introduced fishes, which emphasises the need for evidence‐based studies of non‐native species impacts.

“…The effects of non‐native species on ecosystem function also varies by trophic level, functional group, and the invader's ability to modify habitats (Gallardo et al, 2016). For example, top‐down effects can occur via the introduction of zooplanktivores (Ordóñez et al, 2010) or bottom‐up effects through the introduction of filter‐feeding planktivores (Ward & Ricciardi, 2007). Trait‐variation is also positively correlated with the invasability of a species, which generates cascading effects on recipient ecosystems (Evangelista, Lecerf, Britton, & Cucherousset, 2017; Mitchell & Bakker, 2014).…”

Large rivers are susceptible to anthropogenic alteration, which can result in drastic changes to their functional ecology. We evaluated spatial–temporal changes in the functional fish communities of the Upper Mississippi River System (UMRS) using data from six study reaches. Species were classified into one of 14 feeding guilds and mass per unit effort (MPUE) was then calculated for each feeding guild annually per gear type. MPUE was standardized using the multigear mean standardization method (MGMS) and log‐transformed. Both ANOSIM and Chi‐square tests were used to determine differences in MPUE among reaches. We then estimated functional diversity by calculating the number of functional groups (N), Margalef's d, Pielou's J′, Shannon's Diversity, and Simpson's Diversity Index. An AR(1) time series model was used to investigate proportional changes in each guild over 25 years. To evaluate the effect of invasive Carp species in invaded reaches, a Chow test was applied to observations between 2000 and 2005. Analyses revealed differences in the functional fish community among reaches. We found differences in functional diversity metrics among study reaches, but there was little evidence that this differed between invaded and non‐invaded reaches. Results determined that invertivore/detritivores have been consistently declining system‐wide, with few groups showing a net change. There was also little evidence that invasion altered the proportion of any functional guild. Evaluating the spatial–temporal patterns of functional communities is beneficial to understanding the resilience of a system and can provide further insight into its trophic needs when considering future restoration initiatives.
