“…The ability of M. mexicanus, and other species with a broad distribution, to adapt to climate change depends on both phenotypic plasticity and the genetic diversity available to selection (Menzel and Feldmeyer 2021, Vranken et al 2021, Martin et al 2023). Mischocyttarus is a neotropical genus, with only a few species that expanded to temperate zones (Silveira 2008, Somavilla et al 2021). Our work suggests a northward expansion that likely depended on genomic evolution that facilitated adaptive responses to seasonality, cold tolerance, and desiccation.…”

Species vary in their ability to adapt to rapid changes, with the presence of genetic variation often facilitating long-term evolutionary responses. Given the impending threat of climate change, it is critical to investigate how genetic variation facilitates persistence and possible range expansion in animals. Here, we combine genomic and climatic data to characterize the drivers of local adaptation in the widely distributed, social wasp Mischocyttarus mexicanus cubicola. Using whole genome sequence data, we show that adaptive genomic variation is linked to a climatic gradient across the broad distribution of this species. We found strong population structure, dividing the species into two genetic clusters that follow subtropical and temperate regions. Patterns of gene flow across the range deviate from those expected by isolation by distance alone with climatic differences resulting in reduced gene flow even between adjacent populations. Importantly, genotype-environment analyses reveal candidate single nucleotide polymorphism (SNPs) associated with temperature and rainfall, suggesting adaptation for thermal and desiccation tolerance. In particular, candidate SNPs in or near mitochondrial genes ND5, CO1, and COIII are linked to cold tolerance and metabolism. Similarly, the Gld nuclear gene shown to mediate cold hardiness and cuticle formation, shows two candidate SNPs with non-synonymous mutations unique to temperate populations. Together, our results reveal candidate SNPs consistent with local adaptation to distinct climatic conditions. Thus, the integration of genomic and climatic data can be a powerful approach to predict vulnerability and persistence of species under rapid climate change.

“…In Brazil, the Polistinae fauna encompasses 21 genera and nearly 380 described species. Two clades are recognized in the genus Polistes: (1) "New World" wasps, comprising the subgenera Aphanilopterus, Palisotius, Epcinemius, Onerarius, and Fuscopolistes distributed throughout Americas and Europe; and (2) "Old World" wasps, including Gyrostoma, Stenopolistes, Nygmopolistes, Megapolistes, Polistella, Sulcopolistes, and Polistes sensu stricto distributed over the Eastern/Indo-Malaysian region (Somavilla et al 2021 with Polistinae being the most studied subfamily (Menezes et al 2014). Despite the utility of cytogenetic data for the systematic of distinct taxa, the small size and the high number of chromosomes in insects, besides technological issues, might have hindered the karyotype characterization of most species (Koçak and Okutaner 2017).…”

Cytogenetic techniques have been improving over the last decades, providing useful information for the systematics and evolution of several groups, such as social insects. On the other hand, karyotypic data are still incipient for most wasp genera. For instance, only five of the 240 species of Polistes have been karyotyped, usually based on obsolete data. Therefore, this study aimed to revisit the karyotype structure of Polistes canadensis, providing unpublished information based on traditional (karyotyping and C-banding) and refined (GC- and AT-rich sites by base-specific fluorochrome staining) cytogenetic methods. Males and females of P. canadensis were characterized by haploid and diploid numbers of n = 28 and 2n = 56, respectively. The karyotype formula was established in 2K = 18M + 22SM + 16A with a predominance of pericentromeric heterochromatin and terminal GC+ sites in 16 chromosome pairs. Our results differ significantly from the previous karyotype reported for this species, probably related to the utilization of suitable methods of obtaining mitotic chromosomes in the present study. In addition, the detailed analysis of chromosomal microstructure provided potential cytotaxonomic markers for systematic inferences in social wasps.
