“…Our results therefore support the idea that invasive organisms experience a distorted distance landscape in which vector activity complements, or possibly even replaces, geographic separation as distance measure (LaRue et al . ; Darling et al . ; Ghabooli et al .…”

Colonization events, range expansions and species invasions leave genetic signatures in the genomes of invasive organisms and produce intricate special patterns. Predictions have been made as to how those patterns arise, but only very rarely, genetic processes can be monitored in real time during range expansions. In an attempt to change that, we track a very recently established invasive population of a fish species, the bighead goby Ponticola kessleri, with high temporal and spatial resolution through 2 years to identify patterns over time. We then compare Swiss and German samples of bighead goby along the river Rhine using microsatellites, mitochondrial D-loop sequences and geometric morphometrics to investigate geographic patterns. We detect weak temporal and strong geographic patterns in the data, which are inconsistent with isolation by distance and indicate long range transport. In search of an explanation for our observations, we analyse the vector properties and travel patterns of commercial vessels on the river Rhine. We present evidence that freshwater cargo ships and tankers are plausible vectors for larvae of invasive goby species. We also present indications that cargo ships and tankers act as differential vectors for this species. In summary, we present genetic data at unique temporal resolution from a vertebrate invasion front and substantiate the paramount role of commercial shipping in freshwater fish translocations.

“…In addition to directed establishment of coquies, humans may facilitate jump dispersal inadvertently, by transporting infested nursery plants over long distances or by coquies climbing aboard vehicles that subsequently travel long distances. Jump dispersal is indicated by a lack of correlation between genetic distance and geographical distance such that two populations in close proximity are genetically dissimilar (LaRue et al ., ). Because population establishment of the coqui has occurred along roadways and in residential areas, it is very likely that humans are playing an important role in their dispersal.…”

Aim The coqui frog (Eleutherodactylus coqui) was introduced to the Hawai'ian archipelago in the late 1980s and became established as a widespread species on Hawai'i Island over a short timespan, suggesting that humans are facilitating their movement. To determine the importance of human facilitation, we assessed dispersal patterns and genetic structure of coqui populations using microsatellite data. Location Hawai'i Island. Methods We obtained genotype data using seven microsatellites from coqui specimens collected from 25 populations on Hawai'i Island. The dispersal mechanism was examined using a Mantel test in GenAlEx and a genetic distance tree analysis in Phylip. Allelic diversity, measures of equilibrium, and genetic structure were analysed in GenAlEx and Arlequin. The correlation between genetic distance and geographical distance was used to distinguish between diffusion dispersal (positive correlation) and jump dispersal (zero or negative correlation). Results The Mantel test for isolation by distance found no significant correlation between genetic and geographical distance (r2 = 0.002, P = 0.4401). The genetic distance tree topology is consistent with this result and exhibited a pattern expected if population establishment occurred through jump dispersal. Migration rates were high (NM = 4.228), inbreeding was high, genetic differentiation between populations was low, and significant genetic structure was detected among populations (4% of total variation, P < 0.002). Main conclusions Genetic distance is not correlated with geographical distance, suggesting that humans are important facilitators of coqui dispersal. Migration rate was high, indicating that the rapid expansion of coquies on Hawai'i Island was human‐facilitated, while high levels of inbreeding and significant genetic structure suggest low post‐establishment dispersal. If this is the case, early detection of coqui populations will be crucial for management due to their propensity to be spread through human‐facilitated jump dispersal, followed by slow rates of diffusion dispersal from these newly established populations.

“…Heino (2013), for instance, attributes a negative relationship between local community similarity and distance (i.e., distance decay) to high dispersal. In the Great Lakes, population genetic structure of the round goby showed evidence of isolation by distance (analogous to distance decay; Finn & Poff 2011), as gene flow (a surrogate of dispersal) was higher between coastal sites in closer spatial proximity (LaRue et al 2011). In other cases, environmental conditions contribute to distance decay.…”

Freshwater river mouths in large lakes are centres of biological activity, yet little is understood about the spatial and temporal dynamics of fish communities in these systems. In the Laurentian Great Lakes, we sampled littoral fishes over 3 years in six drowned (i.e., protected) river mouths to: (i) quantify spatial (among river mouths) and temporal (among years) variation, (ii) evaluate associations with environmental conditions and (iii) assess spatial patterns of community similarity. We sampled 6787 fish representing 43 species over the course of the study. Multivariate analyses indicated that variation in fish species composition was more strongly partitioned among river mouths than among years. Fish communities across the six river mouths were partitioned into three groups, a pattern we attribute to variability in anthropogenic disturbance and environmental conditions. Canonical correspondence analysis showed that fish species composition was associated with specific conductivity, vegetation cover, turbidity and pH, suggesting species-environment relationships are similar to those shown for Great Lakes coastal wetlands. Finally, we found a negative relationship between geographic distance and community similarity, suggesting that dispersal and/or environmental gradients play a role in shaping these river mouth fish assemblages. We conclude that Great Lakes drowned river mouths can harbour diverse and spatially variable fish assemblages that are driven by a combination of local and regional factors.
