While the effects of grazing on individual forest attributes are well documented, their integrated consequences remain poorly understood, particularly in temperate forest ecosystems. We evaluated the combined influence of livestock grazing intensity and canopy cover on individual attributes and ecosystem multifunctionality in native Nothofagus forests of Tierra del Fuego, Argentina. Across eight ranches spanning two agroecological regions (Ecotone and Mountain Range), we quantified forest regeneration, understorey richness and biomass, and soil properties, integrating them into a multifunctionality index. Using generalized linear mixed models, we found strong context-dependence: in the Mountain Range, higher grazing intensity reduced seedling and sapling density, organic matter content, coarse woody debris, and overall multifunctionality. In the Ecotone, these effects of livestock use intensity were attenuated, and canopy cover diminished sapling density and multifunctionality, but moderate cover enhanced understorey. Our results extend multifunctionality research from grazed grasslands to grazed temperate forests and show that ecological responses and trade-offs vary across landscape units. We conclude that the Mountain Range is more vulnerable to grazing, requiring stricter management, whereas the Ecotone retains greater capacity to sustain multifunctionality under controlled livestock use intensity. These findings underscore the importance of region-specific silvopastoral strategies that reconcile food production with forest conservation in southern Patagonia and comparable temperate forest landscapes worldwide.' acknowledgement: We would like to thank Guillermo Ortiz (CADIC-CONICET) for his invaluable support in the field and lab work.

Here, we analyze genes that control differences in the gradient of yellow flower color between two varieties of snapdragon (Antirrhinum). We show that these differences depend, in part, on cis-regulatory variation in the pigment biosynthetic gene, FLAVIA (FLA). FLA interacts multiplicatively with three other loci, one of which is a trans-acting regulator of FLA, to further shape the yellow gradient. All the loci exhibit clines at a hybrid zone, with widths that correlate with phenotypic effect, showing how selection can hone gradient shape with remarkable precision by acting on cis and trans variation at multiple loci. acknowledgement: We thank C.

Much effort has focused on\r\nlocating candidate genes and potential barrier loci by scanning genomes for regions\r\nof excess differentiation (FST). An alternative, and perhaps more robust approach, is\r\nto scan for genomic regions exhibiting steep clines in allele frequency across a hybrid\r\nzone. We develop a computationally efficient method for approximating cline parameters\r\nfor large number of loci, and apply it to genomic data from across a hybrid zone\r\nbetween flower colour varieties of Antirrhinum majus (A. m. m var. pseudomajus and\r\nA. m. m var. striatum). Most steep clines are clustered in seven genomic regions,\r\nonly four of which were present from FST scans between all pair-wise comparisons.\r\nSix of these regions carry previously identified loci that influence flower colour in the\r\nhybrid zone. The seventh region harbours a novel locus, RUBIA, modifying magenta\r\nintensity. Clines at RUBIA approached fixation on the magenta side of the hybrid\r\nzone, whilst remaining polymorphic on the yellow side. This polymorphism on the\r\nyellow side may reflect a smaller phenotypic effect of RUBIA in yellow compared\r\nto magenta genetic backgrounds. Our findings illustrate how whole-genome cline\r\nscans in hybrid zones can robustly detect genomic regions contributing to phenotypic\r\ndifferences and highlight how different reproductive barrier loci interact across the\r\ngenome." acknowledgement: This work was supported by the Biotechnology and Biological Sciences Research Council (https://www.ukri.org/councils/bbsrc/) (grants BB/S009256/1, BB/G009325/1, BBS/E/JI/230002C, and BBS/E/J/000PR9773 to EC, and Norwich Research Park Biosciences Doctoral Training Partnership grant (https://www.jic.ac.uk/training-careers/postgraduate-opportunities/nrp-doctoral-training-partnership/) (BB/M011216/1 to DR) and European Research Council (https://erc.europa.eu/homepage) ERC Advanced Grant HaplotypeStructure (101055327 to NB).

Decades-long efforts yielded TF-DNA interaction models that predict how strongly an individual TF binds arbitrary DNA sequences and how individual binding events on the CRE combine to affect gene expression. These insights can be synthesized into a global, biophysically realistic, and quantitative genotype-phenotype (GP) map for gene regulation, a ‘holy grail’ for the application of evolutionary theory. A global map provides a rare opportunity to simulate the long-term evolution of regulatory sequences and pose several fundamental questions: How long does it take to evolve CREs de novo? How many non-trivial regulatory functions exist in sequence space? How connected are they? For which regulatory architecture is CRE evolution most rapid and evolvable? In this article, the second of a two-part series, we review the application of evolutionary concepts — epistasis, robustness, evolvability, tunability, plasticity, and bet-hedging — to the evolution of gene regulatory sequences. We then evaluate the potential for a unifying theory for the evolution of regulatory sequences and identify key open challenges.' acknowledgement: "We thank Calin Guet and Santiago Herrera-Álvarez for essential contributions to this manuscript.\r\nE.M. acknowledges support from the APART-USA fellowship, jointly funded by the Austrian Academy of Sciences (ÖAW) and the Institute of Science and Technology Austria (ISTA).

How spinal circuits and their cell types evolved to support this transition remains unclear. We leverage frog metamorphosis, which recapitulates this transition within a single organism, to define how spinal circuits generate aquatic versus terrestrial motor patterns. At swim stages, spinal architecture is uniform, with a transcriptionally and anatomically homogeneous motor and interneurons. As limbs develop and their movement complexifies, spinal circuits expand in neuron number and subtype diversity. This expansion is most pronounced for V1 inhibitory neurons, which increase ∼70-fold and diversify into transcriptionally distinct subtypes. Disrupting transcription factors defining emerging motor and V1 populations reveals molecular segregation between swim and limb circuits, highlighting the role of subtype diversity in motor coordination. A multifold increase in inhibitory neuron diversity thus underlies the tail-to-limb locomotor transition, providing a framework for spinal circuit adaptation during vertebrate evolution. acknowledged_ssus: - _id: Bio - _id: LifeSc acknowledgement: 'We would like to thank the members of the Sweeney Lab, Mario de Bono, Michael Forsthofer, Katharina Lust, and Meital Oren, for comments on the manuscript.

This mutation–selection–drift balance (MSDB) shapes the prevalence of a disease and its genetic architecture. To date, however, MSDB has been modeled only for monogenic (Mendelian) diseases. Here, we develop an MSDB model for complex disease susceptibility: we assume that genotype relates to disease risk according to the canonical liability threshold model and that the selection on variants affecting risk stems from the fitness cost of the disease. We focus on diseases that are highly polygenic, entail a substantial fitness cost, and are neither extremely common in the population nor exceedingly rare. The comparison of model predictions with genome-wide association studies and other observations in humans indicates that common genetic variation affecting complex disease susceptibility is little affected by directional selection and instead shaped by pleiotropic stabilizing selection on other traits. In turn, directional selection may exert a more substantial effect on rare, large-effect variants. Our results also suggest that current estimates of disease heritability are likely biased. The model thus provides a better understanding of the evolutionary processes that shape the architecture and prevalence of complex diseases.' acknowledgement: We thank Nick Barton, Magnus Nordborg, John Novembre, Molly Przeworski, and Himani Sachdeva for many helpful discussions and for comments on the manuscript, and we thank Joshua Schraiber and 2 anonymous reviewers for comments on the manuscript.

Two varieties of wild snapdragon (Antirrhinum majus) characterized by divergent flower color hybridize in their native range. Selection on flower color genes is indicated by sharp clines, but the selective agents have not been demonstrated. Although previous work has focused on pollinators, pigmentation genes can also contribute to abiotic stress tolerance. We hypothesized that pigmentation in A. majus mediates stress tolerance, which could contribute to hybrid zone maintenance through parental niche divergence or hybrid maladaptation. Specifically, we tested whether morphotype mediates drought tolerance in an experiment comparing magenta-flowered var. pseudomajus, yellow-flowered var. striatum, and their pink-flowered hybrid cross.\r\nMethods: We experimentally compared drought tolerance of each morphotype from allopatric crosses within and between varieties using three greenhouse treatments. Control plants were watered as needed, while drought-treated plants were watered half as often, either from the transplant stage (“early” drought), or from flowering onset (“late” drought).\r\nResults: Parental morphotypes responded identically to drought in fitness and most phenotypic traits. However, hybrids had lower survival (14%) under late drought stress than parental morphotypes (70%). All hybrids that flowered in the late drought treatment died, compared to ~20% of flowering parental morphotypes.\r\nConclusions: Hybrid maladaptation to abiotic stress could potentially contribute to flower color divergence in the face of gene flow in A. majus. Further research should test the relevance of our results to field conditions and explicitly probe the role of flower color genes in drought tolerance." acknowledgement: Thank you to Doug Schemske and Nick Barton forcritically reviewing the manuscript, Beatriz Pablo Car-mona for assisting with data collection, Melinda Pickupand Eva Cereghetti for seedlings, and Louise Arathoon,Ksenia Khudiakova, Georg Rieckh, Daria Shiplina, andAnja Westram for help with experimental maintenance.We sincerely thank the Associate Editor Brenda Grewelland two anonymous reviewers for their thoughtfulcomments and suggestions, which substantially improved the clarity and quality of our manuscript.

Higher load causes population numbers to decline, which reduces the efficiency of selection and further increases load, resulting in a positive feedback that may drive entire populations to extinction. Here, we investigate this eco-evolutionary feedback in a metapopulation consisting of local demes connected via migration, with individuals subject to deleterious mutation at a large number of loci. We first analyze the determinants of load under soft selection, where population sizes are fixed, and then build on this to understand hard selection, where population sizes and load coevolve. We show that under soft selection, very little gene flow (less than one migrant per generation) is enough to prevent fixation of deleterious alleles. By contrast, much higher levels of migration are required to mitigate load and prevent extinction when selection is hard, with critical migration thresholds for metapopulation persistence increasing sharply as the genome-wide deleterious mutation rate becomes comparable to the baseline population growth rate. Moreover, critical migration thresholds are highest if deleterious mutations have intermediate selection coefficients but lower if alleles are predominantly recessive rather than additive (due to more efficient purging of recessive load within local populations). Our analysis is based on a combination of analytical approximations and simulations, allowing for a more comprehensive understanding of the factors influencing load and extinction in fragmented populations. acknowledgement: 'This research was partially funded by the Austrian Science Fund (FWF P-32896B) and DOC Fellowships of the Austrian Academy of Sciences: grants 26380 (O.O.) and 26293 (K.K.).

Evidence from model organisms shows INDELs to be more strongly influenced by purifying selection than SNPs. Partly for this reason, INDELs are rarely used as markers for demographic processes or to detect divergent selection. Here, we compared INDELs and SNPs in the intertidal snail Littorina saxatilis, focussing on hybrid zones between ecotypes, in order to test the utility of INDELs in the detection of divergent selection. We computed INDEL and SNP site frequency spectra using capture sequencing data. We assessed the impact of divergent selection by analyzing allele frequency clines across habitat boundaries. We also examined the influence of GC-biased gene conversion because it may be confounded with signatures of selection. We show evidence that short INDELs are affected more by purifying selection than SNPs, but part of the observed site frequency spectra difference can be attributed to GC-biased gene conversion. We did not find a difference in the impact of divergent selection between short INDELs and SNPs. Short INDELs and SNPs were similarly distributed across the genome and so are likely to respond to indirect selection in the same way. A few regions likely affected by divergent selection were revealed by INDELs and not by SNPs. Short INDELs can be useful (additional) genetic markers helping to identify genomic regions important for adaptation and population divergence." acknowledgement: "This work was supported by the Natural Environment Research Council (NE/K014021/1), European Research Council (ERC-2015-AdG-693030- BARRIERS) and Swedish Research Council VR (2018-03695) and we are also very grateful for the support of the Linnaeus Centre for Marine Evolutionary Biology at the University of Gothenburg.\r\nWe thank the Swedish Bioinformatics Advisory Program organized by SciLifeLab for feedback and assistance on the variant calling pipeline and Alan Le Moan for helpful discussions.

Climate change is expected to induce shifts in the composition, structure and functioning of Arctic tundra ecosystems. Increases in the frequency and severity of tundra fires have the potential to catalyse vegetation transitions with far-reaching local, regional and global consequences.\r\n2. We propose that post-fire tundra recovery, coupled with climate change, may not necessarily lead to pre-fire conditions. Our hypothesis, based on surveys and literature, suggests two climate–fire driven trajectories. One trajectory results in increased woody vegetation under low fire frequency; the other results in grass dominance under high frequency.\r\n3. Future research should address uncertainties regarding possible tundra ecosystem shifts linked to fires, using methods that encompass greater temporal and spatial scales than previously addressed. More case studies, especially in underrepresented regions and ecosystem types, are essential to broaden the empirical basis for forecasts and potential fire management strategies.\r\n4. Synthesis. Our review synthesises current knowledge on post-fire vegetation trajectories in Arctic tundra ecosystems, highlighting potential transitions and alternative ecosystem states and their implications. We discuss challenges in defining and predicting these trajectories as well as future directions." acknowledgement: We would like to express our sincere gratitude to all the data providers who carried out fieldwork in different regions of the Arctic and published their data, which we used for our meta-analysis.

The phenomenon of the saprotrophic-mycorrhizal divide highlights the difference in the stable isotope composition of fruiting bodies of mycorrhizal and saprotrophic fungi. Much less is known about the isotopic composition of the mycelium, which plays an important role in the formation of the soil organic matter and fuels the fungal trophic channel in soil food webs. In this study, we assessed whether the saprotrophic-mycorrhizal divide in the natural δ13С and δ15N values can be traced throughout entire fungal organisms. This hypothesis was tested using 16 species of ectomycorrhizal and six species of saprotrophic basidiomycetous fungi. We showed that not only fruiting bodies, but also the mycelium of ectomycorrhizal and saprotrophic fungi differs in the δ13C and δ15N values. In both ectomycorrhizal and saprotrophic fungi, the δ13C and δ15N values increased from mycelium to hymenophores and correlated positively with the total N content in the corresponding tissues. The differences between ectomycorrhizal and saprotrophic mycelium can be used to reconstruct the fungal-driven belowground carbon and nitrogen allocation, and the contribution of saprotrophic and mycorrhizal fungi to soil food webs. acknowledgement: We thank Sergey Tsurikov for the help with stable isotope analysis.

Prior studies in South American temperate forests have mainly focused on initial stages, lacking a comprehensive understanding of the entire life cycle within productive systems. We assessed the population dynamics of two key species of mixed forests in northern Patagonia (Austrocedrus chilensis and Nothofagus dombeyi) under two silvopastoral use intensities (high vs. low), using demographic techniques and population projection models. Over 3 years, we quantified vital rates (survival, fertility, growth, reversion and stasis) and used matrix models to calculate deterministic population growth rates (λ). High-intensity silvopastoral use had predominantly negative effects on the elements of the projection matrices of A. chilensis, whereas N. dombeyi exhibited mostly positive or no changes. As a result, projections indicated slight population decreases for A. chilensis (mostly λ < 1) at high silvopastoral use levels compared to low levels, while N. dombeyi showed similar projections (λ ≅ 1) between use levels. Decreased λ for A. chilensis resulted mainly from lower adult tree survival, while early life stages had limited influence on λ for these long-lived species. In summary, silvopastoral use affects population dynamics of key tree species of these mixed forests of northern Patagonia, with implications for sustainable management. Our findings highlight the importance of considering the entire life cycle and suggest targeted practices to enhance A. chilensis populations. acknowledgement: We would like to express our sincere gratitude to the owners of the estates, Lisandro and Oscar Lanfré, Roberto Criado and Yayo Tillería, for allowing us to conduct our research on their properties and for generously sharing their time and knowledge throughout these years.

However, their contribution to genome-wide suppression of gene flow during RI is rarely quantified.\r\nHere, we consider a polygenic “magic” trait that is divergently selected across two populations connected by migration, while also serving as the basis of assortative mating, thus generating sexual selection on one or both sexes. We obtain theoretical predictions for divergence at\r\nindividual trait loci by assuming that the effect of all other loci on any locus can be encapsulated via an effective migration rate, which bears a simple relationship to measurable fitness components of migrants and various early-generation hybrids. Our analysis clarifies how “tipping\r\npoints” (characterized by an abrupt collapse of adaptive divergence) arise, and when assortative mating can shift the critical level of migration beyond which divergence collapses. We quantify the relative contributions of viability and sexual selection to genome-wide barriers to gene\r\nflow and discuss how these depend on existing divergence levels. Our results suggest that effective migration rates provide a useful way of understanding genomic divergence, even in scenarios involving multiple, interacting mechanisms of RI.

A way forward is to compare pairs of ecotypes that evolved in parallel in similar contexts but have reached different degrees of reproductive isolation. Such comparisons are possible in the marine snail Littorina saxatilis by contrasting barriers to gene flow between parallel ecotypes in Spain and Sweden. In both countries, divergent ecotypes have evolved to withstand either crab predation or wave action. Here, we explore transects spanning contact zones between the Crab and the Wave ecotypes using low-coverage whole-genome sequencing, morphological and behavioural traits. Despite parallel phenotypic divergence, distinct patterns of differentiation between the ecotypes emerged: a continuous cline in Sweden indicating a weak barrier to gene flow, but two highly genetically and phenotypically divergent, and partly spatially overlapping clusters in Spain suggesting a much stronger barrier to gene flow. The absence of Spanish early-generation hybrids supported strong isolation, but a low level of gene flow is evident from molecular data. In both countries, highly differentiated loci were located in both shared and country-specific chromosomal inversions but were also present in collinear regions. Despite being considered the same species and showing similar levels of phenotypic divergence, the Spanish ecotypes are much closer to full reproductive isolation than the Swedish ones. Barriers to gene flow of very different strengths between ecotypes within the same species might be explained by dissimilarities in the spatial arrangement of habitats, the selection gradients or the ages of the systems.' acknowledgement: 'This study was supported by European Research Council grant 693030-BARRIERS to RKB; the Swedish Research Council (grant number 2021-04191) to KJ; the Portuguese Foundation for Science and Technology (FCT: 2020.00275.CEECIND and PTDC/BIA-EVL/1614/2021) to RF; grant PID2022-137935NB-I00 by MICIU/AEI/ 10.13039/501100011033/and ERDF/EU (ED431C 2020-05) to JG, grant PID2021-124930NB-I00 funded by MICIU/AEI/ 10.13039/501100011033/and ERDF/EU to ERA, Xunta de Galicia (ED431C 2024/22), Centro singular de Investigación de Galicia accreditation 2024-2027 (ED431G 2023/07), ‘ERDF A way of making Europe’ and Norwegian Research Council RCN, project 315287 to AMW.' article_number: e70025 article_processing_charge: Yes (in subscription journal) article_type: original author: - first_name: Francesca full_name: Raffini, Francesca last_name: Raffini - first_name: Aurélien full_name: De Jode, Aurélien last_name: De Jode - first_name: Kerstin full_name: Johannesson, Kerstin last_name: Johannesson - first_name: Rui full_name: Faria, Rui last_name: Faria - first_name: Zuzanna B. full_name: Zagrodzka, Zuzanna B. last_name: Zagrodzka - 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: Juan full_name: Galindo, Juan last_name: Galindo - first_name: Emilio full_name: Rolán-Alvarez, Emilio last_name: Rolán-Alvarez - first_name: Roger K. full_name: Butlin, Roger K. last_name: Butlin citation: ama: Raffini F, De Jode A, Johannesson K, et al.

Inference can be improved by including information about parentage shared between siblings, or by modelling phenotypes or population data related to mating. However, we currently lack a framework to infer parent–offspring relationships, sibships and population parameters in a single analysis. To address this, we here extend a previous method, Fractional Analysis of Paternity and Sibships, to include population data for the case where one parent is known. We illustrate this with the example of pollen dispersal in a natural hybrid zone population of the snapdragon Antirrhinum majus. Pollen dispersal is leptokurtic, with half of mating events occurring within 30 m, but with a long tail of mating events up to 859 m. Using simulations, we find that both sibship and population information substantially improve pedigree reconstruction, and that we can expect to resolve median dispersal distances with high accuracy. acknowledgement: 'We thank a large number of field volunteers for maintaining the population sampling, and Tom White for assistance with seed collection.

Indeed, it is commonly expected that SD should negatively correlate with the intersex correlation (the genetic correlation between effects of segregating variants in females and males, r fm), either because (1) traits with ancestrally low r fm are less constrained in their ability to respond to sex-specific selection and thus evolve to be more dimorphic, or because (2) sex-specific selection, driving sexual dimorphism evolution, also acts to reduce r fm. Despite the intuitive appeal and prominence of these ideas, their generality and the conditions in which they hold remain unclear. Here, we develop models incorporating sex-specific stabilizing selection, mutation and genetic drift to examine the relationship between r fm and SD. We show that the two commonly-discussed mechanisms with the potential to generate a negative correlation between SD and r fm could just as easily generate a positive association, since the standard line of reasoning hinges on a hidden assumption that sex-specific adaptation more frequently favors increased dimorphism than reduced dimorphism. Our results provide, to our knowledge, the first mechanistic framework for understanding the conditions under which a correlation between r fm and SD may arise and offer a compelling explanation for inconsistent empirical evidence. We also make the intriguing observation that—even when selection between the two sexes is identical—drift generates nonzero SD.

Recognizing these interactions during early-life stages provides valuable insights for restoration in human-disturbed areas. One promising approach is nucleation planting, which establishes small clusters of native species in strategically selected sites, being particularly useful in sites with large herbivores. In southern Patagonia, livestock production has historically been the main economic activity, severely impacting extensive areas of Nothofagus antarctica forest through grazing and intentional burning to increase forage. In this context, nucleation planting with Berberis microphylla, a non-palatable shrub, could foster forest recovery in degraded sites. To evaluate this, we conducted an experiment testing the response of trees to varying shrub number, while also assessing intraspecific effects in both species. We measured survival, biomass, and functional traits. Results showed that the combination of four shrubs surrounding a single tree maintained tree survival at levels comparable to trees growing alone, while seedlings exhibited conspecific negative plant number dependence. Additionally, B. microphylla increased its below- to above-ground biomass ratio under higher plant number, indicating resource reallocation and niche differentiation through spatial separation of root systems. article_processing_charge: No article_type: original author: - first_name: Gimena Noemí full_name: Bustamante, Gimena Noemí last_name: Bustamante - first_name: Miriam Elisabet full_name: Arena, Miriam Elisabet last_name: Arena - first_name: Luciano full_name: Selzer, Luciano last_name: Selzer - first_name: Matthew full_name: Ruggirello, Matthew last_name: Ruggirello - first_name: Paula full_name: Rodríguez, Paula last_name: Rodríguez - first_name: Samuele full_name: Pedrazzani, Samuele last_name: Pedrazzani - first_name: Jose Antonio full_name: Navarro-Cano, Jose Antonio last_name: Navarro-Cano - first_name: Rosina Matilde full_name: Soler Schaller, Rosina Matilde id: 9e668447-8c32-11ed-b0c7-8dc2d7b80803 last_name: Soler Schaller citation: ama: 'Bustamante GN, Arena ME, Selzer L, et al.

By increasing local drift, population structure may thus amplify the evolutionary advantage of sex. However, most previous models have focused either on haploid populations or on diploid populations without spatial structure. In this article, we use two- and three-locus analytical models and multilocus simulations to explore selection for sex in a diploid population structured according to the island model, in the presence of recurrent deleterious mutations. Our results show that selection generally favors an intermediate rate of sex that decreases as the direct cost of sex increases and increases moderately as the degree of population structure increases. Selection for sex is generated by multiple effects involving genetic associations within and between loci. When selection occurs at many loci, it is generally dominated by interference effects involving deleterious alleles at different loci, captured by our three-locus model. In our multilocus simulations, we observed an irreversible spread of asexual mutants under strong costs of sex, and when deleterious mutations are partially recessive. However, population structure may prevent this spread of asexual mutants when dispersal rates are sufficiently small. acknowledgement: L.F. is funded by the NOMIS-ISTA Fellowship Program.

Traditional population genomic approaches that rely on site-based statistics in\r\narbitrary fixed windows face inherent limitations, as they conflate historical and\r\ncontemporary processes of divergence and overlook haplotype structure. Recent advances in\r\nwhole-genome sequencing and methods to infer ancestral recombination graphs (ARGs) now\r\noffer the opportunity to study genealogical relationships explicitly, revealing how lineages\r\ncoalesce and recombine through time. By directly analysing haplotype clustering by species\r\nor phenotype and their patterns of coalescence, ARG-based methods show promise for\r\ndiagnosing sweeps, identifying barrier loci maintained under divergent selection amid gene\r\nflow, and tracing their evolutionary history.\r\nIn this thesis, I explore the utility of genealogical approaches for studying species\r\ndivergence. In chapter 2, I propose a conceptual framework for defining haplotype blocks\r\nthrough the structure of the ARG, using simulations and empirical data to highlight how\r\ngenealogical processes generate rich and often overlooked haplotypic patterns.\r\nIn chapter 3, I examine the genomic basis of a key evolutionary innovation in marine\r\nsnails Littorina. These snails offer a unique opportunity to study an innovation because they\r\ninclude a very recent transition from egg-laying to live bearing, yet snails with the different\r\nreproductive modes are not reciprocally monophyletic. I exploited this by using topology\r\nclustering in ARG-derived local genealogical trees to pinpoint narrow genomic regions or\r\nhaplotype blocks that carry swept alleles, thus revealing that the transition from egg-laying\r\nto live-bearing involves multiple, live-bearer-specific sweeps.\r\nChapter 4 establishes a population-scale, phased genomic resource for Antirrhinum\r\nmajus, using cost-effective haplotagging, then optimizes imputation from low-coverage data\r\nagainst high-accuracy KASP sequencing to maximize sequence completeness with modest\r\naccuracy trade-offs against a traditional short-read sequence pipeline. A hybrid phasing\r\nstrategy combines molecular phasing with statistical phasing to generate phased whole\r\ngenome sequences of 1084 Antirrhinum individuals at a fraction of long-read sequencing\r\ncosts.\r\nIn chapter 5, I analyse hybridising populations from two replicate hybrid zones to find\r\na parallel genetic basis of flower colour, amidst the noise in genomic differentiation landscape\r\ndriven by variation in demographic history. While outlier genome scans of FST failed to dissect\r\nthe causes of differentiation, ARG-based topology clustering revealed a reuse of colour\r\nassociated haplotypes across hybrid zones. In addition to the biological insight, this chapter\r\nalso presents a comparison of the latest ARG inference tools, showing that signals of\r\nAbstract\r\nviii\r\ntopological clustering qualitatively agree between methods, despite differences in the tree\r\nsequences.\r\nNext, in chapter 6, by leveraging ~1000 individuals in one of the hybrid zones, I\r\nintegrated genome-wide association studies of floral pigmentation with genealogical\r\ninference, to test for additional colour loci, and confirm the effect of previously described loci.\r\nThis work demonstrates that flower colour variation is driven by a small number of large effect\r\nloci, while also hinting at the presence of a new candidate regulatory factor.\r\nFinally in chapter 7, in a preliminary analysis, I begin to dissect the genomic island of\r\nspeciation around Rosea/Eluta to understand its evolutionary origins. My results show that it\r\nconsists of 5 highly divergent loci, each of which is associated with flower colour. Using\r\npatterns of coalescence in genealogical trees, I find evidence of staggered selective sweeps\r\nand a persistent localized barrier to gene flow within an otherwise permeable genome.\r\nTogether, these chapters add to the increasing pool of studies using genealogical\r\napproaches to complement and extend site-based statistics to use haplotype structures in\r\nspeciation research. By tracking haplotypes directly and connecting genealogical clustering to\r\npopulation processes, ARG-based inference promises to provide new insights into how local\r\nselective pressures, demographic history, and long-term barriers interact to shape the\r\ngenomic architecture of divergence. By underscoring the value of ARGs in revealing the finescale origins and maintenance of biodiversity, this thesis presents cautious optimism about\r\nthe benefits of using genealogical inference to learn more than what site-based statistics\r\ncould tell us." acknowledged_ssus: - _id: ScienComp alternative_title: - ISTA Thesis article_processing_charge: No author: - first_name: Arka full_name: Pal, Arka id: 6AAB2240-CA9A-11E9-9C1A-D9D1E5697425 last_name: Pal orcid: 0000-0002-4530-8469 citation: ama: Pal A.
