Data from: Standing genetic diversity and selection at functional gene loci are associated with differential invasion success in two non-native fish species
Invasive species are expected to experience a unique combination of high genetic drift due to demographic factors while also experiencing strong selective pressures. The paradigm that reduced genetic diversity should limit the evolutionary potential of invasive species and thus their potential for range expansion has received little empirical support, possibly due to the choice of genetic markers. Our goal was to test for effects of genetic drift and selection at functional genetic markers as they relate to the invasion success of two paired invasive goby species, one widespread (successful) and one with limited range expansion (less successful). We genotyped fish using two marker types: single nucleotide polymorphisms (SNPs) in known-function, protein-coding genes and microsatellites to contrast the effects of neutral genetic processes. We identified reduced allelic variation in the invaded range for the less-successful tubenose goby. SNPs putatively under selection were responsible for the observed differences in population structure between marker types for round goby (successful) but not tubenose goby (less successful). A higher proportion of functional loci experienced divergent selection for round goby, suggesting increased evolutionary potential in invaded ranges may be associated with round goby's greater invasion success. Genes involved in thermal tolerance were divergent for round goby populations but not tubenose goby, consistent with the hypothesis that invasion success for fish in temperate regions is influenced by capacity for thermal tolerance. Our results highlight the need to incorporate functional genetic markers in studies to better assess evolutionary potential for the improved conservation and management of species.

Genetic loci associated with winter survivorship in diverse lowland switchgrass populations: SNP read count data
<p>High winter mortality is the most important factor limiting biomass yield of lowland switchgrass planted in the northern latitudes of North America. Due to the perennial growth habit and strong dependence on weather conditions to generate sufficient selection pressure to identify winter-hardy individuals, breeding of cold tolerant switchgrass cultivars requires many years. Identification of causal genetic variants for winter survivorship would accelerate the improvement of switchgrass biomass production. The objective of this study was to identify allelic variation associated with winter survivorship in lowland switchgrass populations using bulk segregant analysis (BSA). Twenty-nine lowland switchgrass populations were evaluated for winter survival at two locations in southern Wisconsin and 21 population with differential winter survivorship was used for BSA. A maximum of 10% of the individuals per population (8-20) was bulked to create survivor and non-survivor DNA pools. The DNA pools were evaluated using exome capture sequencing and allele frequencies were used to conduct statistical tests. The BSA tests revealed nine QTL from tetraploid populations and seven QTL from octoploid populations. Some markers were identified in multiple populations that originated across a broad geographic landscape, while other markers were site-specific. QTL at positions 88 Mb on chromosome 2N, 115 Mb on chromosome 5K, and 1 and 100 Mb on chromosome 9N were potentially the most useful QTL. Markers associated with winter survivorship in this study can be used to accelerate breeding cycles of lowland switchgrass populations and should lead to improvements in adaptation within USDA hardiness zones 4 and 5.</p>
