Summary Restriction site‐associated DNA sequencing (RAD‐seq) provides high‐resolution population genomic data at low cost, and has become an important component in ecological evolutionary studies. As with all high‐throughput technologies, analytic strategies require critical validation to ensure precise unbiased interpretation. To test the impact of bioinformatic processing on downstream genetic inferences, we analysed mammalian RAD‐seq (>100 individuals) 312 combinations methodology ( de...
Mutation and recombination are key evolutionary processes governing phenotypic variation reproductive isolation. We here demonstrate that biodiversity within all globally known strains of Schizosaccharomyces pombe arose through admixture between two divergent ancestral lineages. Initial hybridization was inferred to have occurred ∼20-60 sexual outcrossing generations ago consistent with recent, human-induced migration at the onset intensified transcontinental trade. Species-wide heritable...
Abstract Mitigating trade-offs between different resource-utilization functions is key to an organism’s ecological and evolutionary success. These often reflect metabolic constraints with a complex molecular underpinning; therefore, their consequences for processes have remained elusive. Here, we investigate how architecture induces these constraints, in turn, elicit specialization diversification. Guided by the network structure of bacterium Lactococcus cremoris, selected two carbon sources...
Sexual reproduction in eukaryotes requires the fusion of two compatible gametes opposite sexes or mating types. To meet challenge finding a partner with gametes, evolutionary mechanisms such as hermaphroditism and self-fertilization have repeatedly evolved. Here, by combining insights from comparative genomics, computer simulations experimental evolution fission yeast, we shed light on conditions promoting separate types self-compatibility mating-type switching. Analogous to multiple...
Phenotypic differences between individuals of a species are often caused by in gene expression, which turn genetic variation. Expression quantitative trait locus (eQTL) analysis is methodology we can identify such causal variants. Scaling eQTL costly due to the expense generating mapping populations, and collection matched transcriptomic genomic information. We developed rapid approach using single-cell/nucleus RNA sequencing gametes from small number heterozygous individuals. Patterns...
Abstract The fission yeast Schizosaccharomyces pombe is an important model organism, but its natural diversity and evolutionary history remain under-studied. In particular, the population genomics of S. mitochondrial genome (mitogenome) has not been thoroughly investigated. Here, we assembled complete circular-mapping mitogenomes 192 isolates de novo, found that these belong to 69 nonidentical sequence types ranging from 17,618 26,910 bp in length. Using mitogenomes, identified 20 errors...
Hybridization is thought to reactivate transposable elements (TEs) that were efficiently suppressed in the genomes of parental hosts. Here, we provide evidence for this "genomic shock hypothesis" fission yeast Schizosaccharomyces pombe In species, two divergent lineages (Sp and Sk) have experienced recent, likely human-induced, hybridization. We used long-read sequencing data assemble 37 samples derived from 31 S. strains spanning a wide range ancestral admixture proportions. A comprehensive...
ABSTRACT Adaptive divergence is the key evolutionary process generating biodiversity by means of natural selection. Yet, conditions under which it can arise in presence gene flow remain contentious. To address this question, we subjected 132 sexually reproducing fission yeast populations sourced from two independent genetic backgrounds to disruptive ecological selection and manipulated level migration between environments. Contrary theoretical expectations, adaptive was most pronounced when...
Species are seen as the fundamental unit of biotic diversity, and thus their delimitation is crucial for defining measures diversity assessments studying evolution. Differences between species have traditionally been associated with variation in morphology. And yet, discovery cryptic suggests that evolution distinct lineages does not necessarily involve morphological differences. Here, we analyze 1,684,987 variant sites over 4,000 genes more than 400 samples to show how a tropical montane...
Iconographic evidence from Egypt suggests that watermelon pulp was consumed there as a dessert by 4,360 BP. Earlier archaeobotanical comes seeds Neolithic settlements in Libya, but whether these were watermelons with sweet or other forms is unknown. We generated genome sequences 6,000- and 3,300-year-old Libya Sudan, worldwide herbarium collections made between 1824 2019, analyzed data together resequenced genomes important germplasm for total of 131 accessions. Phylogenomic...
Abstract Expression divergence, rather than sequence has been shown to be important in speciation, particularly the early stages of divergence traits involved reproductive isolation. In two European subspecies house mice, Mus musculus and domesticus , earlier studies have demonstrated olfactory‐based assortative mate preference populations close their hybrid zone. It suggested that this behaviour evolved following recent secondary contact between taxa (~3,000 years ago) response selection...
Population outbreaks of the corallivorous crown-of-thorns seastar (COTS), Acanthaster 'planci' L., are among most important biological disturbances tropical coral reefs. Over past 50 years, several devastating have been documented around Guam, an island in western Pacific Ocean. Previous analyses shown that Ocean, COTS larval dispersal may be geographically restricted to certain regions. Here, we assess genetic structure populations and compared samples from Guam with a number distant...
Olfactory learning and floral scents are co-adaptive traits in the plant-pollinator relationship. However, how scent relates to cognition diverse group of Neotropical stingless bees is largely unknown. Here we evaluated ability Melipona eburnea be conditioned using proboscis extension reflex (PER) protocol. Stingless did not show PER while harnessed but were able when free-to-move a mini-cage (fmPER). We effect of: 1) unconditioned stimulus (US) reward, 2) previous scent-reward associations...
Abstract Differential dispersion between the sexes can impact population structure and connectivity populations, which in turn, have an effect on evolvability capability of a species. Here we explored demographic history big European firefly, Lampyris noctiluca , exhibits female neoteny. L. distribution extends throughout Europe, but nothing is known how its colonization processes. To investigate this, produced first genome (653Mb), including IsoSeq annotation identification X chromosome. We...

Summary Amazon parrots stand out as one of the most illegally traded Psittacids in neotropics. However, lack effective tools for determining geographical origin confiscated individuals has impeded development well-informed release programmes. In this study, we evaluated efficacy cytochrome oxidase subunit I (COI) gene to identify phylogeographical groups and infer origins seized across six parrot species. Through comprehensive genetic phylogenetic analyses 140 COI sequences from with...
