“…Secondly, Ahrens et al (2005) reported a sharp genetic discontinuity in the native distribution of fire ants along the border between Argentina and Brazil. In this region, a 2500 km-long geographical barrier to gene flow (the Mesopotamia wetlands) divides the distribution of fire ants into two evolutionary independent groups, one in the south-western portion of the range and the other in the north-eastern portion (Ahrens et al, 2005). Environments characteristic of the counties first invaded by fire ants occur primarily to the west of this division.…”

“…First, preliminary genetic analyses of native and invasive fire ant populations also suggest that the most likely source of individuals founding the US population is the southern half of the native range, and north-eastern Argentina in particular (Mescher et al, 2003).

Aim The use of species distribution models (SDMs) to predict biological invasions is a rapidly developing area of ecology. However, most studies investigating SDMs typically ignore prediction errors and instead focus on regions where native distributions correctly predict invaded ranges. We investigated the ecological significance of prediction errors using reciprocal comparisons between the predicted invaded and native range of the red imported fire ant ( Solenopsis invicta ) (hereafter called the fire ant). We questioned whether fire ants occupy similar environments in their native and introduced range, how the environments that fire ants occupy in their introduced range changed through time relative to their native range, and where fire ant propagules are likely to have originated.Location We developed models for South America and the conterminous United States (US) of America. MethodsWe developed models using the Genetic Algorithm for Rule-set Prediction (GARP) and 12 environmental layers. Occurrence data from the native range in South America were used to predict the introduced range in the US and vice versa. Further, time-series data recording the invasion of fire ants in the US were used to predict the native range.Results Native range occurrences under-predicted the invasive potential of fire ants, whereas occurrence data from the US over-predicted the southern boundary of the native range. Secondly, introduced fire ants initially established in environments similar to those in their native range, but subsequently invaded harsher environments. Time-series data suggest that fire ant propagules originated near the southern limit of their native range.Conclusions Our findings suggest that fire ants from a peripheral native population established in an environment similar to their native environment, and then ultimately expanded into environments in which they are not found in their native range. We argue that reciprocal comparisons between predicted native and invaded ranges will facilitate a better understanding of the biogeography of invasive and native species and of the role of SDMs in predicting future distributions.

“…Avise (2009) pointed out that low dispersal species are characterized by strong genealogical structure, but emphasized that 'even in vagile species, historical barriers to dispersal can sometimes be insurmountable', promoting high population structure. Indeed, this pattern was also found in two species of ants with flying queens: Solenopsis invicta (Ahrens, Ross & Shoemaker, 2005) and Formica pratensis (Goropashnaya et al 2007).…”

Dinoponera lucida (Formicidae; Ponerinae) is an extinction-threatened species of ant which is endemic in the central corridor of the Atlantic Forest. We used mitochondrial sequences of the Cox1, Cox2 and Cytb genes in order to infer some aspects of the evolutionary history and phylogeography of this ant. High genetic divergence and population structure were observed for the whole species. The current pattern of D. lucida diversity seems to be shaped during different geological times: middle Pliocene, early Pleistocene and mainly late Pleistocene, when the reduction of populations generated a structure pattern of the genetic variation of this species. Our data show that this structure results from the maintenance of populations of D. lucida within very small putative refuges to the south of the central Bahia refugium. We thus argue that, for some Atlantic forest endemic species, especially those resistant to very small fragments of forest, such as D. lucida, the small putative refuges were as important as, or even more important than, larger and stable refuges for the creation and maintenance of diversity, adding another piece to the puzzle of the mechanisms underlying local endemism.

“…Polymerase chain reactions for the mtDNA included primers C1-J-2195 and DDS-COII-4 (Ross & Shoemaker 1997) designed to specifically amplify an approximately 910 bp fragment corresponding to portions of the cytochrome oxidase subunit I (cox-1) and subunit II (cox-2) genes. PCR reaction conditions and thermal cycling profile were identical to those described in Ahrens et al (2005). PCR products were purified and then used as templates for sequencing reactions performed using the two primers above and the ABI PRISM BigDye Terminator v3.1 Cycle Sequencing Kit (Applied Biosystems, CA, USA).…”

Propagule pressure and colony social organization are associated with the successful invasion and rapid range expansion of fire ants in China

We characterized patterns of genetic variation in populations of the fire ant Solenopsis invicta in China using mitochondrial DNA sequences and nuclear microsatellite loci to test predictions as to how propagule pressure and subsequent dispersal following establishment jointly shape the invasion success of this ant in this recently invaded area. Fire ants in Wuchuan (Guangdong Province) are genetically differentiated from those found in other large infested areas of China. The immediate source of ants in Wuchuan appears to be somewhere near Texas, which ranks first among the southern USA infested states in the exportation of goods to China. Most colonies from spatially distant, outlying areas in China are genetically similar to one another and appear to share a common source (Wuchuan, Guangdong Province), suggesting that long-distance jump dispersal has been a prevalent means of recent spread of fire ants in China. Furthermore, most colonies at outlier sites are of the polygyne social form (featuring multiple egg-laying queens per nest), reinforcing the important role of this social form in the successful invasion of new areas and subsequent range expansion following invasion. Several analyses consistently revealed characteristic signatures of genetic bottlenecks for S. invicta populations in China. The results of this study highlight the invasive potential of this pest ant, suggest that the magnitude of international trade may serve as a predictor of propagule pressure and indicate that rates and patterns of subsequent range expansion are partly determined by the interplay between species traits and the trade and transportation networks.
