Threespine Stickleback: A Model System For Evolutionary Genomics

Annual Review of Genomics and Human Genetics, Journal Year: 2021, Volume and Issue: 22(1), P. 357 - 383

Published: April 28, 2021

The repeated adaptation of oceanic threespine sticklebacks to fresh water has made it a premier organism study parallel evolution. These small fish have multiple distinct ecotypes that display wide range diverse phenotypic traits. Ecotypes are easily crossed in the laboratory, and families large develop quickly enough for quantitative trait locus analyses, positioning stickleback as versatile model address biological questions. Extensive genomic resources, including linkage maps, high-quality reference genome, developmental genetics tools led insights into basis identification changes controlling traits vertebrates. Recently, been used system identify highly complex traits, such behavior host–microbiome host–parasite interactions. We review latest findings new avenues research be considered supermodel evolutionary genomics.

Three problems in the genetics of speciation by selection

Proceedings of the National Academy of Sciences, Journal Year: 2022, Volume and Issue: 119(30)

Published: July 18, 2022

Speciation is the process by which barriers to gene flow evolve between populations. Although we now know that speciation largely driven natural selection, knowledge of agents selection and genetic genomic mechanisms facilitate divergence required for a satisfactory theory speciation. In this essay, highlight three advances/problems in our understanding have arisen from studies genes regions underlie evolution reproductive isolation. First, describe how identification “speciation” makes it possible identify causing isolation, while also noting link genetics phenotypic intrinsic postzygotic remains tenuous. Second, discuss important role recombination suppressors facilitating with flow, but point out means timing become associated cold spots uncertain. Third, establish importance ancient variation speciation, although argue focus on evolutionarily young groups may bias conclusions favor relative new mutations.

Rapid adaptive radiation of Darwin’s finches depends on ancestral genetic modules

Science Advances, Journal Year: 2022, Volume and Issue: 8(27)

Published: July 8, 2022

Recent adaptive radiations are models for investigating mechanisms contributing to the evolution of biodiversity. An unresolved question is relative importance new mutations, ancestral variants, and introgressive hybridization phenotypic speciation. Here, we address this issue using Darwin’s finches investigate genomic architecture underlying their diversity. Admixture mapping beak body size in small, medium, large ground revealed 28 loci showing strong genetic differentiation. These represent haplotype blocks with origins predating speciation events during finch radiation. Genes expressed developing overrepresented these regions. Ancestral haplotypes constitute modules selection act as key determinants unusual diversity finches. Such can be critical how species adapt environmental variability change.

Evolutionary gain and loss of a pathological immune response to parasitism

Science, Journal Year: 2022, Volume and Issue: 377(6611), P. 1206 - 1211

Published: Sept. 8, 2022

Parasites impose fitness costs on their hosts. Biologists often assume that natural selection favors infection-resistant Yet, when the immune response itself is costly, theory suggests may sometimes favor loss of resistance, which result in alternative stable states where some populations are resistant and others tolerant. Intraspecific variation rarely surveyed a manner tests evolutionary patterns, there few examples adaptive resistance. Here, we show marine threespine stickleback colonized freshwater lakes, they gained resistance to freshwater-associated cestode Schistocephalus solidus. Extensive peritoneal fibrosis inflammation commonly observed phenotype contributes suppression growth viability but also imposes substantial cost fecundity. Combining genetic mapping population genomics, find opposing generates system differences between tolerant populations, consistent with divergent optimization.

Population Structure Limits Parallel Evolution in Sticklebacks

Molecular Biology and Evolution, Journal Year: 2021, Volume and Issue: 38(10), P. 4205 - 4221

Published: May 5, 2021

Abstract Population genetic theory predicts that small effective population sizes (Ne) and restricted gene flow limit the potential for local adaptation. In particular, probability of evolving similar phenotypes based on shared mechanisms (i.e., parallel evolution), is expected to be reduced. We tested these predictions in a comparative genomic study two ecologically geographically codistributed stickleback species (viz. Gasterosteus aculeatus Pungitius pungitius). found P. pungitius harbors less diversity exhibits higher levels differentiation isolation-by-distance than G. aculeatus. Conversely, stronger degree parallelism across freshwater populations pungitius: 2,996 versus 379 single nucleotide polymorphisms located within 26 9 regions show evidence selection multiple pungitius, respectively. Most involved evolution showed increased divergence, suggestive ancient haplotypes. contrast, haplotypes adaptation were younger. accordance with theory, results suggest connectivity drift play crucial roles determining geographic distribution standing variation, providing subdivision limits therefore also likelihood evolution.

Recognizing Salinity Threats in the Climate Crisis

Integrative and Comparative Biology, Journal Year: 2022, Volume and Issue: 62(2), P. 441 - 460

Published: May 31, 2022

Abstract Climate change is causing habitat salinity to transform at unprecedented rates across the globe. While much of research on climate has focused rapid shifts in temperature, far less attention effects changes environmental salinity. Consequently, predictive studies physiological, evolutionary, and migratory responses organisms populations threats are relatively lacking. This omission represents a major oversight, given that among most important factors define biogeographic boundaries aquatic habitats. In this perspective, we briefly touch occurring contemporary time scales. We then discuss might confer resilience certain taxa, enabling them survive shifts. Next, consider approaches for predicting how geographic distributions will shift response change. Finally, identify additional data needed make better predictions future. Future should account multiple rapidly changing, especially

Predicting rapid adaptation in time from adaptation in space: A 30-year field experiment in marine snails

Science Advances, Journal Year: 2024, Volume and Issue: 10(41)

Published: Oct. 11, 2024

Predicting the outcomes of adaptation is a major goal evolutionary biology. When temporal changes in environment mirror spatial gradients, it opens up potential for predicting course adaptive evolution over time based on patterns genetic and phenotypic variation. We assessed this approach 30-year transplant experiment intertidal snail Littorina saxatilis . In 1992, snails were transplanted from predation-dominated to one dominated by wave action. On basis patterns, we predicted transitions shell size morphology, allele frequencies at positions throughout genome, chromosomal rearrangement frequencies. Observed closely agreed with predictions transformation was both dramatic rapid. Hence, can be knowledge variation among populations.

Chromosomal Fusions Facilitate Adaptation to Divergent Environments in Threespine Stickleback

Molecular Biology and Evolution, Journal Year: 2021, Volume and Issue: 39(2)

Published: Dec. 12, 2021

Chromosomal fusions are hypothesized to facilitate adaptation divergent environments, both by bringing together previously unlinked adaptive alleles and creating regions of low recombination that the linkage alleles; but, there is little empirical evidence support this hypothesis. Here, we address knowledge gap studying threespine stickleback (Gasterosteus aculeatus), in which ancestral marine fish have repeatedly adapted freshwater across northern hemisphere. By comparing ninespine (Pungitius pungitius) genomes a de novo assembly fourspine (Apeltes quadracus) an outgroup species, find two chromosomal fusion events involving same chromosomes occurred independently lineages. On fused stickleback, enrichment quantitative trait loci underlying traits contribute versus adaptation. whole-genome sequences populations, also under selection on these chromosomes. There elevated genetic diversity within population, consistent with simulation study showing gene flow can increase genomic associated local our demographic models between populations. Integrating results previous studies, propose created enabled formation adaptative clusters, thereby facilitating face recurrent sticklebacks.
