“…D. graveolens ’ rapid native range expansion is associated with the evolution of earlier phenology at the range limit and a niche expansion toward more temperate climates, enabling spread well beyond the expectation under climate tracking alone ( Lustenhouwer et al 2018 ; Lustenhouwer and Parker 2022 ). The reference genome presented here provides an opportunity to study the genomic basis of these impactful eco-evolutionary processes and will advance the emerging field of climate change genomics in plants ( Lancaster et al 2022 ).…”

Dittrichia graveolens (L.) Greuter, or stinkwort, is a weedy annual plant within the family Asteraceae. The species is recognized for the rapid expansion of both its native and introduced ranges: in Europe, it has expanded its native distribution northward from the Mediterranean basin by nearly 7 degrees latitude since the mid-20th century, while in California and Australia the plant is an invasive weed of concern. Here, we present the first de novo Dittrichia graveolens genome assembly (1N=9 chromosomes), including complete chloroplast (151,013 bp) and partial mitochondrial genomes (22,084 bp), created using Pacific Biosciences HiFi reads and Dovetail Omni-C data. The final primary assembly is 835 Mbp in length, of which 98.1% are represented by nine scaffolds ranging from 66 to 119 Mbp. The contig N50 is 74.9 Mbp and the scaffold N50 is 96.9 Mbp, which, together with a 98.8% completeness based on the BUSCO embryophyta10 database containing 1614 orthologs, underscores the high quality of this assembly. This pseudomolecule-scale genome assembly is a valuable resource for our fundamental understanding of the genomic consequences of range expansion under global change, as well as comparative genomic studies in the Asteraceae.

“…First, genetic variation for traits under selection needs to be abundant, and population size sufficiently large, to sustain population growth during environmental change (Bürger & Lynch, 1995; Lande & Shannon, 1996). Whether or not fitness-related traits typically harbour sufficient genetic variation to permit the rapid evolution that climate change demands is under debate (Angert et al, 2020; Bonnet et al, 2022; Kokko et al, 2017; Lancaster et al, 2022) and will likely differ between traits and the type of environmental change imposed (Agrawal & Whitlock, 2010; Caruso et al, 2017; null Hoffmann & Merilä, 1999; Rowinski & Rogell, 2017). While male reproductive traits can evolve rapidly (Haerty et al, 2007; Swanson & Vacquier, 2002), recent studies indicate that the evolutionary potential of thermal tolerance is limited (Castañeda et al, 2019; Debes et al, 2021; Kellermann & Heerwaarden, 2019; Morgan et al, 2020; Zwoinska et al, 2020).…”

Climates are changing rapidly, demanding equally rapid adaptation of natural populations. Whether sexual selection can aid such adaptation is under debate; while sexual selection should promote adaptation when individuals with high mating success are also best adapted to their local surroundings, the expression of sexually selected traits can incur costs. Here we asked what the demographic consequences of such costs may be once climates change to become harsher and the strength of natural selection increases. We investigated how an evolutionary history of strong postcopulatory sexual selection (sperm competition) affects male fertility under acute adult heat stress. Harnessing the empirical potential of long-term experimental evolution in the seed beetle Callosobruchus maculatus, we assessed the thermal sensitivity of fertility (TSF) in replicated lines maintained for 68 generations under three alternative mating regimes manipulating the opportunity for sexual and natural selection. We find that males evolving under strong sexual selection suffer from increased TSF, and that male success in sperm competition (P2: sperm offense) is genetically correlated to increased TSF. Interestingly, females from the regime under strong sexual selection, who experienced relaxed selection on their own reproductive effort, had high fertility in benign settings but suffered increased TSF, like their brothers. This implies that female fertility and TSF evolved through genetic correlation with reproductive traits sexually selected in males. Paternal but not maternal heat stress reduced offspring fertility with no evidence for adaptive transgenerational plasticity among heat-exposed offspring, indicating that the observed effects may compound over generations. Our results suggest that trade-offs between fertility and traits increasing success in postcopulatory sexual selection can be revealed in harsh environments. This can put polyandrous species under increased risk during extreme heat waves expected under future climate change.

“…Similarly, the population diversification of American pika Ochotona princeps was attributed to climatic fluctuations during the glacial period (Galbreath et al, 2009). Many previous studies had tried to uncover the adaptive genomic responses of populations to climatic pressures (Franks & Hoffmann, 2012; Lancaster et al, 2022). For example, survivors of an extreme cold snap in the southern United States exhibited greater tolerance of cold and heritable changes in four genomic regions that are important for regulation of nervous‐system function in the cold in a population of green anole lizard, Anolis carolinensis (Campbell‐Staton et al, 2017).…”

Climate is a fundamental abiotic factor that plays a key role in driving the evolution, distribution and population diversification of species. However, there have been few investigations of genomic signatures of adaptation to local climatic conditions in cladocerans. Here, we have provided the first high‐quality chromosome‐level genome assembly (~143 Mb, scaffold N50 12.6 Mb) of the waterflea, Daphnia galeata, and investigated genomic variation in 22 populations from Central Europe and Eastern China. Our ecological‐niche models suggested that the historic distribution of D. galeata in Eurasia was significantly affected by Quaternary climate fluctuations. We detected pronounced genomic and morphometric divergences between European and Chinese D. galeata populations. Such divergences could be partly explained by genomic signatures of thermal adaptation to distinct climate regimes: a set of candidate single‐nucleotide polymorphisms (SNPs) potentially associated with climate were detected. These SNPs were in genes significantly enriched in the Gene ontology terms “determination of adult lifespan” and “translation repressor activity”, and especially, mthl5 and SOD1 involved in the IIS pathway, and EIF4EBP2 involved in the target of the rapamycin signalling pathway. Our study indicates that certain alleles might be associated with particular temperature regimes, playing a functional role in shaping the population structure of D. galeata at a large geographical scale. These results highlight the potential role of molecular variation in the response to climate variation, in the context of global climate change.
