Data from: Unexpected patterns of segregation distortion at a selfish supergene in the fire ant Solenopsis invicta
Background: The Sb supergene in the fire ant Solenopsis invicta determines the form of colony social organization, with colonies whose inhabitants bear the element containing multiple reproductive queens and colonies lacking it containing only a single queen. Several features of this supergene — including suppressed recombination, presence of deleterious mutations and abundant transposable elements, association with a large centromere, and "green-beard" behavior — suggest that it may be a selfish genetic element that engages in transmission ratio distortion (TRD), defined as significant departures in progeny allele frequencies from Mendelian inheritance ratios. We tested this possibility by surveying segregation ratios in embryo progenies of 101 queens of the "polygyne" social form (3512 embryos) using three supergene-linked markers and twelve markers not associated with the supergene. Results: Significant departures from Mendelian ratios were observed at the supergene loci in 3-5 times more progenies than expected in the absence of TRD and than found, on average, among non-supergene loci. Also, supergene loci displayed the greatest mean deviations from Mendelian ratios among all study loci, although these typically were modest. A surprising feature of the observed inter-progeny variation in TRD was that significant deviations involved not only excesses of supergene alleles but also similarly frequent excesses of the alternate alleles on the homologous chromosome. As expected given the common occurrence of such "drive reversal," alleles associated with the supergene evidently gain no consistent transmission advantage over their alternate alleles at the population level. Finally, we observed low levels of recombination and incomplete gametic disequilibrium across the supergene, including between adjacent markers within a single inversion. Conclusions: Our data confirm the prediction that the Sb supergene is a selfish genetic element capable of biasing its own transmission during reproduction, yet counterselection for suppressor loci evidently has produced an evolutionary stalemate in TRD between the variant homologous haplotypes on the "social chromosome". Evidence implicates prezygotic segregation distortion as responsible for the TRD we document, with "true" meiotic drive the most likely mechanism. Low levels of recombination and incomplete gametic disequilibrium across the supergene suggest that selection does not act to preserve a single uniform supergene haplotype.

The occurrence records of Solenopsis invicta
<p>We initially built a robust database of occurrence data for S. invicta, covering its native range (South America) and invaded range (North America). Occurrence records of S. invicta were obtained from Global Biodiversity Information Facility (GBIF; https://www.gbif.org/), AntWeb (https://www.antweb.org/) and AntMap (https://antmaps.org/). We also incorporated distribution records of S. invicta provided by Wetterer (2013) into the dataset. To minimize spatial sampling bias, we used the nearest neighbor distance (NND) method to thin the data, where occurrence points that were less than 1 km from each other were removed. In parallel, we noted that there were still some distribution records of S. invicta in regions north of 40° North Latitude, although S. invicta is considered a tropical insect. We consulted online distribution records of S. invicta at the Centre for Agriculture and Biosciences International (CABI; https://www.cabidigitallibrary.org/doi/10.1079/cabicompendium.50569), and National Invasive Species Information Center (NISIC; https://www.invasivespeciesinfo.gov/terrestrial/invertebrates/red-imported-fire-ant), but no clear information could be found to support the accuracy of the distribution records at these high latitudes. We thus removed these records to avoid interference caused by the temporary, seasonal distribution and possible erroneous records. Therefore, a total of 6,122 records (421 and 5,701 for the native and invaded ranges, respectively) were retained.</p>

Data from: Decreased small mammal and on-host tick abundance in association with invasive red imported fire ants (Solenopsis invicta)
Invasive species may impact pathogen transmission by altering the distributions and interactions among native vertebrate reservoir hosts and arthropod vectors. Here, we examined the direct and indirect effects of the red imported fire ant (Solenopsis invicta) on the native tick, small mammal and pathogen community in southeast Texas. Using a replicated large-scale field manipulation study, we show that small mammals were more abundant on treatment plots where S. invicta populations were experimentally reduced. Our analysis of ticks on small mammal hosts demonstrated a threefold increase in the ticks caught per unit effort on treatment relative to control plots, and elevated tick loads (a 27-fold increase) on one common rodent species. We detected only one known human pathogen (Rickettsia parkeri), present in 1.4% of larvae and 6.7% of nymph on-host Amblyomma maculatum samples but with no significant difference between treatment and control plots. Given that host and vector population dynamics are key drivers of pathogen transmission, the reduced small mammal and tick abundance associated with S. invicta may alter pathogen transmission dynamics over broader spatial scales.
