“…A similar pattern was observed in the invasion process of the European green crab in North America, in which two separately introduction events led to two genetically distinct groups (FitzGerald et al, 2017;Jeffery et al, 2017). Although natural and artificial barriers in rivers can define the spatial distribution or expansion of freshwater invasive species (see Teixeira et al, 2020), the limited admixture in both genetic groups of red swamp crayfish (Badajoz and Lower Guadalquivir) suggests an effect related to the political border between Spain and Portugal. The border has apparently favoured the existence of two quasi-independent expansion processes, despite both countries share several river basins through which natural dispersion of invasive species may occur (Gago, Anastácio, Gkenas, Banha & Ribeiro, 2016).…”

The human-mediated dispersal process seemed to have involved invasion hubs, hosting highly genetically diverse areas and acting as sources for subsequent introductions. Genetic diversity also tended to be higher in more suitable environments across the Iberian Peninsula. 6. Our results showed that the complex and human-mediated expansion of the red swamp crayfish in the Iberian Peninsula has involved several long-and short-distance movements and that both ecological and anthropogenic factors have shaped the genetic diversity patterns resulting from this invasion process. Early detection of potential invasion hubs may help to halt multiple shortdistance translocations and thus the rapid expansion of highly prolific invasive species over nonnative areas.

“…However, depletion of genetic diversity induced by bottleneck events could even increase population fitness and boost invasiveness in some situations (e.g., by purging deleterious mutations) (Marchini et al, 2016), and increase additive genetic variance for ecological relevant traits (Lindholm et al, 2005). In T. cirratus , despite the lower levels of gene diversity in invasive populations, they were still able to become invasive, a pattern reported in other invasive fishes (e.g., white piranha Serrasalmus brandtii , Teixeira et al, 2020; and largemouth bass Micropterus salmoides , Hargrove et al, 2017).…”

Patterns of genetic diversity: Stepping‐stone dispersal of an invasive fish introduced by an inter‐basin water transfer project

et al. 2022

Knowledge of large‐scale dispersal processes and their associated genetic diversity patterns is significant for managing invasive species. These patterns remain unclear for invasive species that colonise new habitats through inter‐basin water transfer projects. A worm goby Taenioides cirratus colonised several large inland lakes in China, thereby expanding its distribution through the East Route of the South‐to‐North Water Transfer Project (ESNT). Here, we used nuclear microsatellites to analyse patterns of genetic diversity, population structure, gene flow and, invasion history across its native and invasive ranges in China. Our objectives were to: (a) reveal contemporary genetic diversity patterns of T. cirratus in two native and four invasive populations in China; and (b) identify its main model of dispersal in the ESNT. Invasive populations experienced significant loss of genetic diversity because of bottlenecks and low levels of gene flow, and strong population genetic structure due to founder effects that occurred during expansions. Significant genetic isolation‐by‐distance patterns were largely influenced by landscape connectivity and the reduced active dispersal ability of T. cirratus. The one‐way stepping‐stone dispersal model was identified as being most likely for T. cirratus in the ESNT, influenced by the long distance of upstream dispersal and downstream water transfer events. Our results highlight that T. cirratus could overcome low genetic diversity in founding populations, allowing for invasive spread. For management, we suggest physical removal of invasive populations and installation of deterrents near the pump intake area and the lake outflow to reduce further spread in the system. We provided a general paradigm for understanding dispersal patterns involved in inter‐basin water transfers.

“…Most of the fish captured using gill nets were a non‐native predator species (white piranha— Serrasalmus brandtii ) that colonised and established at UHE Irapé reservoir (Teixeira et al, 2020). In this study, the white piranha represented 66.5% of all individuals (Table 3).…”

Despite the large number of dams in most important rivers of Brazil, little is known about fish vertical distribution in neotropical reservoirs, especially deep ones. This study aims to understand how fish were vertically distributed in the deepest reservoir in Brazil, located in the Jequitinhonha River. Three areas of the reservoir were sampled quarterly using an echosounder. The deepest fish detected was at 115 m, but most were shallower than 25 m. Diel vertical migration of fish was detected, but not in all the sampling areas and campaigns. Fish distribution was determined by several limnological factors of the reservoir, but mainly by thermal variation in water column. These results can provide guidance for environmental and fisheries managers and ecologists to improve sampling techniques in deep reservoirs since vertical distribution and its relation with habitat use are determinant to propose management measures in similar ecosystems.
