“…Local adaptation is another important evolutionary process that may be linked to successful invasion (Bock et al, 2015; Lee, 2002; Medley et al, 2019; Szucs et al, 2017; Yadav et al, 2021). Rapid evolutionary adaptation can occur following or prior to invasion events, as documented by comparisons of invading and source populations of invaders (Comeault et al, 2020; Ellstrand & Schierenbeck, 2000; Krieger & Ross, 2002; Sherpa et al, 2019).…”

Invasive species pose increasing threats to global biodiversity and ecosystems. While previous studies have characterized successful invaders based on ecological traits, characteristics related to evolutionary processes have rarely been investigated. Here we compared gene flow and local adaptation using demographic analyses and outlier tests in two co‐occurring moth pests across their common native range of China, one of which (the peach fruit moth, Carposina sasakii) has maintained its native distribution, while the other (the oriental fruit moth, Grapholita molesta) has expanded its range globally during the past century. We found that both species showed a pattern of genetic differentiation and an evolutionary history consistent with a common southwestern origin and northward expansion in their native range. However, for the noninvasive species, genetic differentiation was closely aligned with the environment, and there was a relatively low level of gene flow, whereas in the invasive species, genetic differentiation was associated with geography. Genome scans indicated stronger patterns of climate‐associated loci in the noninvasive species. While strong local adaptation and reduced gene flow across its native range may have decreased the invasiveness of C. sasakii, this requires further validation with additional comparisons of invasive and noninvasive species across their native range.

“…Thus, over fine spatial scales, selection is thought to typically favor generalist phenotypes or phenotypically plastic genotypes whose traits depend on local environmental cues (Levins, 1968;Hollander, 2008;Baythavong, 2011). Despite this, there is emerging evidence that local adaptation frequently does occur over microgeographic scales (i.e., well within the species' dispersal neighborhood) (e.g., Hargeby et al, 2004;Antonovics, 2006;Richter-Boix et al, 2013;Yadav et al, 2020), indicating that either selection is stronger or gene flow is more restricted than typically assumed (Richardson et al, 2014).…”

Nearshore foundation species in coastal and estuarine systems (e.g., salt marsh grasses, mangroves, seagrasses, corals) drive the ecological functions of ecosystems and entire biomes by creating physical structure that alters local abiotic conditions and influences species interactions and composition. The resilience of foundation species and the ecosystem functions they provide depends on their phenotypic and genetic responses to spatial and temporal shifts in environmental conditions. In this review, we explore what is known about the causes and consequences of adaptive genetic differentiation in marine foundation species over spatial scales shorter than dispersal capabilities (i.e., microgeographic scales). We describe the strength of coupling field and laboratory experiments with population genetic techniques to illuminate patterns of local adaptation, and we illustrate this approach by using several foundation species. Among the major themes that emerge from our review include (1) adaptive differentiation of marine foundation species repeatedly evolves along vertical (i.e., elevation or depth) gradients, and (2) mating system and phenology may facilitate this differentiation. Microgeographic adaptation is an understudied mechanism potentially underpinning the resilience of many sessile marine species, and this evolutionary mechanism likely has particularly important consequences for the ecosystem functions provided by foundation species.

“…Population genomic approaches applied to wild populations increasingly provide the power needed to detect dispersal across fine temporal scales down to single generations, which can reveal movement patterns at correspondingly fine spatial scales (Combs et al, 2018; Jasper et al, 2019; Trense et al, 2020). Spatial genomic studies conducted across a restricted temporal range may also help shed new light on adaptive processes such as the spread of advantageous alleles through wild populations (Endersby‐Harshman et al, 2020; Fitzpatrick et al, 2010; Pélissié et al, 2018) and local adaptation in microgeographically structured environments (Yadav et al, 2020).…”

Spatial population genomics of a recent mosquito invasion

Population genomic approaches can characterize dispersal across a single generation through to many generations in the past, bridging the gap between individual movement and intergenerational gene flow. These approaches are particularly useful when investigating dispersal in recently altered systems, where they provide a way of inferring long‐distance dispersal between newly established populations and their interactions with existing populations. Human‐mediated biological invasions represent such altered systems which can be investigated with appropriate study designs and analyses. Here we apply temporally restricted sampling and a range of population genomic approaches to investigate dispersal in a 2004 invasion of Aedes albopictus (the Asian tiger mosquito) in the Torres Strait Islands (TSI) of Australia. We sampled mosquitoes from 13 TSI villages simultaneously and genotyped 373 mosquitoes at genome‐wide single nucleotide polymorphisms (SNPs): 331 from the TSI, 36 from Papua New Guinea (PNG) and four incursive mosquitoes detected in uninvaded regions. Within villages, spatial genetic structure varied substantially but overall displayed isolation by distance and a neighbourhood size of 232–577. Close kin dyads revealed recent movement between islands 31–203 km apart, and deep learning inferences showed incursive Ae. albopictus had travelled to uninvaded regions from both adjacent and nonadjacent islands. Private alleles and a co‐ancestry matrix indicated direct gene flow from PNG into nearby islands. Outlier analyses also detected four linked alleles introgressed from PNG, with the alleles surrounding 12 resistance‐associated cytochrome P450 genes. By treating dispersal as both an intergenerational process and a set of discrete events, we describe a highly interconnected invasive system.
