Predicting if, when, and how populations can adapt to climate change constitutes one of the greatest challenges in science today. Here, we build from contributions special issue on evolutionary adaptation change, a survey its authors, recent literature explore limits opportunities for predicting adaptive responses change. We outline what might be predictable now, future, perhaps never even with our best efforts. More accurate predictions are expected traits characterized by well-understood...
Abstract Background Maternally inherited bacteria that reside obligatorily or facultatively in arthropods can increase their prevalence the population by altering hosts' reproduction. Such reproductive manipulations have been reported from major arthropod groups such as insects (in particular hymenopterans, butterflies, dipterans and beetles), crustaceans (isopods) mites. Despite observation endosymbiont are frequently encountered spiders sex ratio of spider species is strongly female...
Many species are expanding their range polewards, and this has been associated with rapid phenotypic change. Yet, it is unclear to what extent reflects genetic adaptation or neutral processes expansion, selection linked the new thermal conditions encountered. To disentangle these alternatives, we studied genomic signature of expansion in damselfly Coenagrion scitulum using 4950 newly developed SNPs rapidly evolved differences between core (newly established) edge populations. Most...
Abstract Geographic range size is a key ecological and evolutionary characteristic of species, yet the causal basis variation in among species remains largely unresolved. One major reason for this that several traits may jointly shape species' differences size. We here present an integrated study contribution (dispersal capacity, body latitudinal position) macroevolutionary (species' age) shaping C oenagrion damselflies. reconstructed phylogenetic tree genus to account history when assessing...
Abstract Due to global change, many species are shifting their distribution and thereby confronted with novel thermal conditions at the moving range edges. Especially during initial phases of exposure a new environment, it has been hypothesized that plasticity associated epigenetic mechanisms enable cope environmental change. We tested this idea by capitalizing on well-documented southward expansion damselfly Ischnura elegans from France into Spain where invaded warmer regions in 1950s...
Abstract Global warming is causing plastic and evolutionary changes in the phenotypes of ectotherms. Yet, we have limited knowledge on how interplay between plasticity evolution shapes thermal responses underlying gene expression patterns. We assessed reaction norm patterns across transcriptome identified associated molecular pathways northern southern populations damselfly Ischnura elegans . Larvae were reared a common garden experiment at mean summer water temperatures experienced (20°C)...
Island faunas exhibit some of the most iconic examples where similar forms repeatedly evolve within different islands. Yet, whether these deterministic evolutionary trajectories islands are driven by an initial, singular divergence and subsequent exchange individuals adaptive genetic variation between remains unclear. Here, we study a gradual, repeated evolution low-dispersive highland ecotypes from dispersive lowland ecotype
Abstract Although genetic diversity provides the basic substrate for evolution, there are a limited number of studies that assess impact recent climate change on intraspecific variation. This study aims to unravel degree which historical and contemporary factors shape structure across large part range range‐expanding damselfly Coenagrion scitulum (Rambur, 1842). A total 525 individuals from 31 populations were genotyped at nine microsatellites, subset was sequenced two mitochondrial genes....
Abstract There is a pressing need to identify the molecular mechanisms underlying the, often magnifying, interactive effects between contaminants and natural stressors. Here we test our hypothesis that lower general stress defence responses contribute synergistic interactions We focus on widespread pattern many are more toxic at higher temperatures. Specifically, tested of an environmentally realistic low‐effect high‐effect concentration pesticide chlorpyrifos under warming gene expression...
Hybrid zones with multiple independent contact regions between the same species allow to determine relative importance of intrinsic and extrinsic factors in evolution hybrid thus, parallelism hybridization outcomes. In this study, we take advantage two damselfly Ischnura elegans I. graellsii Spain measure: i) extent across geographic replicates, what (intrinsic extrinsic) drive that variation; ii) if has an impact on ability expand their ranges. RAD sequencing was used generate 5,702 SNPs...
Contemporary hybrid zones act as natural laboratories for the investigation of species boundaries and may shed light on little understood roles sex chromosomes in divergence. Sex are considered to function a hotspot genetic divergence between species; indicated by less genomic introgression compared autosomes during hybridization. Moreover, they thought contribute Haldane's rule, which states that hybrids heterogametic more likely be inviable or sterile. To test these hypotheses, we used...
1. Many insects are expanding their distribution range polewards as a result of climate change, which has been shown to be associated with founder effects leading reduction in genetic diversity and an increase differentiation. These spatial patterns may arise from colonisation broad expansion front or limited neighbourhood after stepping stone model dispersal. The temporal persistence such poorly understood, mainly because studies looking at the fine‐scale initial dynamics signature rare. 2....
Summary Contemporary climate change triggers a poleward range shift in many species. A growing number of studies document evolutionary changes traits accelerating expansion (such as growth rate and dispersal‐related traits). In contrast, the direct impact decreasing conspecific densities towards very edge front has been neglected. Density effects may, however, have profound on involved influence dynamics. this study, we contrast high larval density typical for established populations low...
The outcome of hybridization is major interest in evolutionary and conservation biology. Here, we investigate (i) the genomic signal dynamics, (ii) strength reproductive barriers preventing copulation heterospecific hybrid crosses, (iii) population dynamics (stability species proportions) two damselfly Ischnura elegans I. graellsii differently aged Spanish regions. RAD sequencing these regions allopatric populations was used to generate 5,702 SNPs quantify diversity differentiation, a subset...
