High species diversity in the sea was regarded as a paradox when strict allopatry was considered necessary for most speciation events because geographical barriers seemed largely absent in the sea, and many marine species have high dispersal capacities. Combining genome-wide data with demographic modelling to infer the demographic history of divergence has introduced new ways to address this classical issue. These models assume an ancestral population that splits into two subpopulations diverging according to different scenarios that allow tests for periods of gene flow. Models can also test for heterogeneities in population sizes and migration rates along the genome to account, respectively, for background selection and selection against introgressed ancestry. To investigate how barriers to gene flow arise in the sea, we compiled studies modelling the demographic history of divergence in marine organisms and extracted preferred demographic scenarios together with estimates of demographic parameters. These studies show that geographical barriers to gene flow do exist in the sea but that divergence can also occur without strict isolation. Heterogeneity of gene flow was detected in most population pairs suggesting the predominance of semipermeable barriers during divergence. We found a weak positive relationship between the fraction of the genome experiencing reduced gene flow and levels of genome-wide differentiation. Furthermore, we found that the upper bound of the ‘grey zone of speciation’ for our dataset extended beyond that found before, implying that gene flow between diverging taxa is possible at higher levels of divergence than previously thought. Finally, we list recommendations for further strengthening the use of demographic modelling in speciation research. These include a more balanced representation of taxa, more consistent and comprehensive modelling, clear reporting of results and simulation studies to rule out nonbiological explanations for general results. acknowledgement: 'We greatly thank all the corresponding authors of the studies that were included in our synthesis for the sharing of additional data: Thomas Broquet, Dmitry Filatov, Quentin Rougemont, Paolo Momigliano, Pierre-Alexandre Gagnaire, Carlos Prada, Ahmed Souissi, Michael Møller Hansen, Sylvie Lapègue, Joseph Di Battista, Michael Hellberg and Carlos Prada.

Here, we examine the homology of sex chromosomes across nine orders of insects, plus the outgroup springtails. We find that the X chromosome is likely homologous across insects and springtails; the only exception is in the Lepidoptera, which has lost the X and now has a ZZ/ZW sex-chromosome system. These results suggest the ancestral insect X chromosome has persisted for more than 450 million years—the oldest known sex chromosome to date. Further, we propose that the shrinking of gene content the dipteran X chromosome has allowed for a burst of sex-chromosome turnover that is absent from other speciose insect orders. acknowledgement: All computational analyses were performed on the server at Institute of Science and Technology Austria.

Interestingly, the X has undergone turnover in multiple fly species (Diptera) after being conserved for more than 450 MY. The long evolutionary distance between Diptera and other sequenced insect clades makes it difficult to infer what could have contributed to this sudden increase in rate of turnover. Here, we produce the first genome and transcriptome of a long overlooked sister-order to Diptera: Mecoptera. We compare the scorpionfly Panorpa cognata X-chromosome gene content, expression, and structure, to that of several dipteran species as well as more distantly-related insect orders (Orthoptera and Blattodea). We find high conservation of gene content between the mecopteran X and the dipteran Muller F element, as well as several shared biological features, such as the presence of dosage compensation and a low amount of genetic diversity, consistent with a low recombination rate. However, the two homologous X chromosomes differ strikingly in their size and number of genes they carry. Our results therefore support a common ancestry of the mecopteran and ancestral dipteran X chromosomes, and suggest that Muller element F shrank in size and gene content after the split of Diptera and Mecoptera, which may have contributed to its turnover in dipteran insects.' acknowledged_ssus: - _id: ScienComp acknowledgement: "We thank the Vicoso lab for their assistance with specimen collection, and Tim Connallon for valuable comments and suggestions on earlier versions of the manuscript.

Interestingly, the X has undergone turnover in multiple fly species (Diptera) after being conserved for more than 450 My. The long evolutionary distance between Diptera and other sequenced insect clades makes it difficult to infer what could have contributed to this sudden increase in rate of turnover. Here, we produce the first genome and transcriptome of scorpionflies (genus Panorpa), an insect belonging to a long overlooked sister-order to Diptera: Mecoptera. Combining our genome assembly with genomic short-read data, we obtain genome coverage and identify X-linked super-scaffolds. We further perform a gene homology analysis between the Panorpa X and a closely related Diptera species, and we assess the conservation of the Panorpa X-linked gene content with that of more distantly related insect species. We explored the structure of the Panorpa X by determining its repeat content, GC content, and nucleotide diversity. Finally, we used RNAseq data to detect the presence of dosage compensation in somatic tissues, as well as to explore gene expression tissue-specificity, and sex-bias in gene expression. We find high conservation of gene content between the mecopteran X and the dipteran Muller F element, as well as several shared biological features, such as the presence of dosage compensation and a low amount of genetic diversity, consistent with a low recombination rate. However, the 2 homologous X chromosomes differ strikingly in their size and number of genes they carry. Our results therefore support a common ancestry of the mecopteran and ancestral dipteran X chromosomes, and suggest that Muller element F shrank in size and gene content after the split of Diptera and Mecoptera, which may have contributed to its turnover in dipteran insects.' article_processing_charge: No author: - first_name: Clementine full_name: Lasne, Clementine id: 02225f57-50d2-11eb-9ed8-8c92b9a34237 last_name: Lasne orcid: 0000-0002-1197-8616 - first_name: Marwan N full_name: Elkrewi, Marwan N id: 0B46FACA-A8E1-11E9-9BD3-79D1E5697425 last_name: Elkrewi orcid: 0000-0002-5328-7231 citation: ama: Lasne C, Elkrewi MN.

Such studies have shed light on how selection changes phenotypes and genotypes. Most of these studies have not examined the time course of adaptation under sexual selection manipulation, by resequencing the populations’ genomes at multiple time points. Here, we analyze allele frequency trajectories in Drosophila pseudoobscura where we altered their sexual selection regime for 200 generations and sequenced pooled populations at 5 time points. The intensity of sexual selection was either relaxed in monogamous populations (M) or elevated in polyandrous lines (E). We present a comprehensive study of how selection alters population genetics parameters at the chromosome and gene level. We investigate differences in the effective population size—Ne—between the treatments, and perform a genome-wide scan to identify signatures of selection from the time-series data. We found genomic signatures of adaptation to both regimes in D. pseudoobscura. There are more significant variants in E lines as expected from stronger sexual selection. However, we found that the response on the X chromosome was substantial in both treatments, more pronounced in E and restricted to the more recently sex-linked chromosome arm XR in M. In the first generations of experimental evolution, we estimate Ne to be lower on the X in E lines, which might indicate a swift adaptive response at the onset of selection. Additionally, the third chromosome was affected by elevated polyandry whereby its distal end harbors a region showing a strong signal of adaptive evolution especially in E lines. acknowledgement: This work was supported by the Vienna Science and Technology Fund (WWTF)(10.47379/MA16061).

This often translates into a\r\nintricate array of sex-specific natural and sexual selection on traits that have a shared\r\ngenetic basis between both sexes, causing a genetic sexual conflict. The resolution of\r\nthis conflict mostly relies on the evolution of sex-specific expression of the shared genes,\r\nleading to phenotypic sexual dimorphism. Such sex-specific gene expression is thought\r\nto evolve via modifications of the genetic networks ultimately linked to sex-determining\r\ntranscription factors. Although much empirical and theoretical evidence supports this\r\nstandard picture of the molecular basis of sexual conflict resolution, there still are a\r\nfew open questions regarding the complex array of selective forces driving phenotypic\r\ndi↵erentiation between the sexes, as well as the molecular mechanisms underlying sexspecific adaptation. I address some of these open questions in my PhD thesis.\r\nFirst, how do patterns of phenotypic sexual dimorphism vary within populations,\r\nas a response to the temporal and spatial changes in sex-specific selective forces? To\r\ntackle this question, I analyze the patterns of sex-specific phenotypic variation along\r\nthree life stages and across populations spanning the whole geographical range of Rumex\r\nhastatulus, a wind-pollinated angiosperm, in the first Chapter of the thesis.\r\nSecond, how do gene expression patterns lead to phenotypic dimorphism, and what\r\nare the molecular mechanisms underlying the observed transcriptomic variation? I\r\naddress this question by examining the sex- and tissue-specific expression variation in\r\nnewly-generated datasets of sex-specific expression in heads and gonads of Drosophila\r\nmelanogaster. I additionally used two complementary approaches for the study of the\r\ngenetic basis of sex di↵erences in gene expression in the second and third Chapters of\r\nthe thesis.\r\nThird, how does intersex correlation, thought to be one of the main aspects constraining the ability for the two sexes to decouple, interact with the evolution of sexual\r\ndimorphism? I develop models of sex-specific stabilizing selection, mutation and drift\r\nto formalize common intuition regarding the patterns of covariation between intersex\r\ncorrelation and sexual dimorphism in the fourth Chapter of the thesis.\r\nAlltogether, the work described in this PhD thesis provides useful insights into the\r\nlinks between genetic, transcriptomic and phenotypic layers of sex-specific variation,\r\nand contributes to our general understanding of the dynamics of sexual dimorphism\r\nevolution." alternative_title: - ISTA Thesis article_processing_charge: No author: - first_name: Gemma full_name: Puixeu Sala, Gemma id: 33AB266C-F248-11E8-B48F-1D18A9856A87 last_name: Puixeu Sala orcid: 0000-0001-8330-1754 citation: ama: 'Puixeu Sala G.

Here, we use allele-specific gene expression of parental and reciprocal hybrid crosses between 6 Drosophila\r\nmelanogaster inbred lines to quantify cis- and trans-regulatory variation in heads and gonads of both sexes separately across 3 replicate\r\ncrosses. Our results suggest that female and male heads, as well as ovaries, have a similar regulatory architecture. On the other hand,\r\ntestes display more and substantially different cis-regulatory effects, suggesting that sex differences in the regulatory architecture that\r\nhave been previously observed may largely derive from testis-specific effects. We also examine the difference in cis-regulatory variation\r\nof genes across different levels of sex bias in gonads and heads. Consistent with the idea that intersex correlations constrain expression\r\nand can lead to sexual antagonism, we find more cis variation in unbiased and moderately biased genes in heads. In ovaries, reduced cis\r\nvariation is observed for male-biased genes, suggesting that cis variants acting on these genes in males do not lead to changes in ovary\r\nexpression. Finally, we examine the dominance patterns of gene expression and find that sex- and tissue-specific patterns of inheritance\r\nas well as trans-regulatory variation are highly variable across biological crosses, although these were performed in highly controlled\r\nexperimental conditions. This highlights the importance of using various genetic backgrounds to infer generalizable patterns." acknowledged_ssus: - _id: ScienComp acknowledgement: We thank members of the Vicoso Group for comments on the manuscript, the Scientific Computing Unit at ISTA for technical support, and 2 anonymous reviewers for useful feedback.

The evolution of X chromosomes after they stop recombining in males, but before they become hemizygous, has not been well explored theoretically. We use the diffusion approximation to infer substitution rates of beneficial and deleterious mutations under such a scenario. Our results show that selection is less efficient on diploid X loci than on autosomal and hemizygous X loci under a wide range of parameters. This “slower-X” effect is stronger for genes affecting primarily (or only) male fitness, and for sexually antagonistic genes. These unusual dynamics suggest that some of the peculiar features of X chromosomes, such as the differential accumulation of genes with sex-specific functions, may start arising earlier than previously appreciated. acknowledgement: We thank the Vicoso and Barton groups and ISTA Scientific Computing Unit.

A largely non-recombining variant of the proximal region of chromosome 17, it is transmitted to more than 90% of the progeny of heterozygous males through the disabling of sperm carrying a standard chromosome. While extensive genetic and functional work has shed light on individual genes involved in drive, much less is known about the evolution and function of the rest of its hundreds of genes. Here, we characterize the sequence and expression of dozens of t-specific transcripts and of their chromosome 17 homologues. Many genes showed reduced expression of the t-allele, but an equal number of genes showed increased expression of their t-copy, consistent with increased activity or a newly evolved function. Genes on the t-haplotype had a significantly higher non-synonymous substitution rate than their homologues on the standard chromosome, with several genes harbouring dN/dS ratios above 1. Finally, the t-haplotype has acquired at least two genes from other chromosomes, which show high and tissue-specific expression. These results provide a first overview of the gene content of this selfish element, and support a more dynamic evolutionary scenario than expected of a large genomic region with almost no recombination. acknowledgement: "This project has received funding from the European Research Council under the European Union’s Horizon 2020 research and innovation program (grant agreement no. 715257) and from the Swiss National Science Foundation (grant no. 310030_189145).\r\nWe thank Jari Garbely of the Department of Evolutionary Biology and Environmental Studies, University of Zurich, Zurich, Switzerland, for conducting the PCR verification.

Together they generate differences in fitness optima between the sexes and result in antagonistic coevolution of female and male reproductive traits. Mounting duration is likely to be a compromise between male and female interests whose outcome depends on the intensity of sexual selection. The timing of sperm transfer during mounting is critical. For example, mountings may be interrupted before sperm is transferred as a consequence of female or male choice, or they may be prolonged to function as mate guarding. In the highly promiscuous intertidal snail Littorina saxatilis, mountings vary substantially in duration, from less than a minute to more than an hour, and it has been assumed that mountings of a few minutes do not result in any sperm being transferred. Here, we examined the timing of sperm transfer, a reproductive trait that is likely affected by sexual conflict. We performed time-controlled mounting trials using L. saxatilis males and virgin females, aiming to examine indirectly when the transfer of sperm starts. We observed the relationship between mounting duration and the proportion of developing embryos out of all eggs and embryos in the brood pouch. Developing embryos were observed in similar proportions in all treatments (i.e. 1, 5 and 10 or more minutes at which mountings were artificially interrupted), suggesting that sperm transfer begins rapidly (within 1 min) in L. saxatilis and very short matings do not result in sperm shortage in the females. We discuss how the observed pattern can be influenced by predation risk, population density, and female status and receptivity. article_number: eyab049 article_processing_charge: No article_type: original author: - first_name: Samuel full_name: Perini, Samuel last_name: Perini - first_name: Rogerk full_name: Butlin, Rogerk last_name: Butlin - first_name: Anja M full_name: Westram, Anja M id: 3C147470-F248-11E8-B48F-1D18A9856A87 last_name: Westram orcid: 0000-0003-1050-4969 - first_name: Kerstin full_name: Johannesson, Kerstin last_name: Johannesson citation: ama: Perini S, Butlin R, Westram AM, Johannesson K.

In vertebrates, interspecific hybridization has repeatedly generated parthenogenetic hybrid species. However, it is unknown whether the generation of parthenogenetic hybrids is a rare outcome of frequent hybridization between sexual species within a genus or the typical outcome of rare hybridization events. Darevskia is a genus of rock lizards with both hybrid parthenogenetic and sexual species. Using capture sequencing, we estimate phylogenetic relationships and gene flow among the sexual species, to determine how introgressive hybridization relates to the origins of parthenogenetic hybrids. We find evidence for widespread hybridization with gene flow, both between recently diverged species and deep branches. Surprisingly, we find no signal of gene flow between parental species of the parthenogenetic hybrids, suggesting that the parental pairs were either reproductively or geographically isolated early in their divergence. The generation of parthenogenetic hybrids in Darevskia is, then, a rare outcome of the total occurrence of hybridization within the genus, but the typical outcome when specific species pairs hybridize. Our results question the conventional view that parthenogenetic lineages are generated by hybridization in a window of divergence. Instead, they suggest that some lineages possess specific properties that underpin successful parthenogenetic reproduction. acknowledgement: "The authors thank A. van der Meijden and F.

In many systems, similar environmental contrasts occur repeatedly, sometimes driving parallel phenotypic evolution. Understanding the genomic basis of local adaptation and parallel evolution is a major goal of evolutionary genomics. It is now known that by preventing the break-up of favourable combinations of alleles across multiple loci, genetic architectures that reduce recombination, like chromosomal inversions, can make an important contribution to local adaptation. However, little is known about whether inversions also contribute disproportionately to parallel evolution. Our aim here is to highlight this knowledge gap, to showcase existing studies, and to illustrate the differences between genomic architectures with and without inversions using simple models. We predict that by generating stronger effective selection, inversions can sometimes speed up the parallel adaptive process or enable parallel adaptation where it would be impossible otherwise, but this is highly dependent on the spatial setting. We highlight that further empirical work is needed, in particular to cover a broader taxonomic range and to understand the relative importance of inversions compared to genomic regions without inversions. acknowledgement: We thank the editor and two anonymous reviewers for their helpful and interesting comments on this manuscript. article_number: '20210203' article_processing_charge: Yes (via OA deal) article_type: original author: - first_name: Anja M full_name: Westram, Anja M id: 3C147470-F248-11E8-B48F-1D18A9856A87 last_name: Westram orcid: 0000-0003-1050-4969 - first_name: Rui full_name: Faria, Rui last_name: Faria - first_name: Kerstin full_name: Johannesson, Kerstin last_name: Johannesson - first_name: Roger full_name: Butlin, Roger last_name: Butlin - first_name: Nicholas H full_name: Barton, Nicholas H id: 4880FE40-F248-11E8-B48F-1D18A9856A87 last_name: Barton orcid: 0000-0002-8548-5240 citation: ama: 'Westram AM, Faria R, Johannesson K, Butlin R, Barton NH.

Although they are known to have ZW chromosomes, these are not well characterized, and it is unclear whether they are shared across the clade. Furthermore, the underlying genetic architecture of the transmission of asexuality, which can occur when rare males mate with closely related sexual females, is not well understood. We produced a chromosome-level assembly for the sexual Eurasian species A. sinica and characterized in detail the pair of sex chromosomes of this species. We combined this new assembly with short-read genomic data for the sexual species A. sp. Kazakhstan and several asexual lineages of A. parthenogenetica, allowing us to perform an in-depth characterization of sex-chromosome evolution across the genus. We identified a small differentiated region of the ZW pair that is shared by all sexual and asexual lineages, supporting the shared ancestry of the sex chromosomes. We also inferred that recombination suppression has spread to larger sections of the chromosome independently in the American and Eurasian lineages. Finally, we took advantage of a rare male, which we backcrossed to sexual females, to explore the genetic basis of asexuality. Our results suggest that parthenogenesis is likely partly controlled by a locus on the Z chromosome, highlighting the interplay between sex determination and asexuality. article_processing_charge: No author: - first_name: Marwan N full_name: Elkrewi, Marwan N id: 0B46FACA-A8E1-11E9-9BD3-79D1E5697425 last_name: Elkrewi orcid: 0000-0002-5328-7231 citation: ama: Elkrewi MN.

In dioecious plants, the sex-determining mechanism may also be disrupted by polyploidization, with the potential evolution of hermaphroditism. However, while dioecy appears to have persisted through a ploidy transition in some species, it is unknown whether the newly formed polyploid maintained its sex-determining system uninterrupted, or whether dioecy re-evolved after a period of hermaphroditism. Here, we develop a bioinformatic pipeline using RNA-sequencing data from natural populations to demonstrate that the allopolyploid plant Mercurialis canariensis directly inherited its sex-determining region from one of its diploid progenitor species, M. annua, and likely remained dioecious through the transition. The sex-determining region of M. canariensis is smaller than that of its diploid progenitor, suggesting that the non-recombining region of M. annua expanded subsequent to the polyploid origin of M. canariensis. Homeologous pairs show partial sexual subfunctionalization. We discuss the possibility that gene duplicates created by polyploidization might contribute to resolving sexual antagonism. acknowledgement: "JRP was supported by the Swiss National Science Foundation (https://www.snf.ch/en), Sinergia grant 26073998.
