Why does reproductive isolation break down between these species?

Most organisms are well adapted to the environment they have been exposed to for many generations. However, changing environments pose existential threats to populations, unless they are able to adapt...

Saturation mutagenesis of the FCY1 promoter in budding yeast shows that adaptation to 5-fluorocytosine is not accessible through single cis-regulatory mutations, despite large mutational effects on pr...

Abstract. Early stages in the adaptive radiation of Darwin’s finches are characterized by divergence (fission) and convergence (fusion) caused by natural s

When two populations come into secondary contact, assortative mating can act as a barrier to gene flow. However, when assortative mating is incomplete, associations between preference and cue loci can...

Human impacts substantially affect our ability to detect and understand natural biodiversity patterns.

Abstract. Examining genomic patterns of differentiation across lineage pairs at different stages of the speciation continuum, in combination with recombina

Abstract. Domestication has profoundly influenced the development of human agriculture, and is characterized by intense artificial selection. Feralization

At this critical moment when misinformation about sex is being applied to policy globally, scientific clarification on the definition of biological sex is valuable. Here, we evaluate the primary appr...

We investigated what factor contributes to a cline of a chromosomal inversion of the Eurasian blackcap, which differs from typical inversion clines maintained by divergent selection. Using a simulati...

AbstractBackground. Obtaining chromosomally complete genome assemblies across the tree of life is an important goal of biodiversity genomics. However, some

Abstract. Hybridization has many and varied impacts on the process of speciation. Hybridization may slow or reverse differentiation by allowing gene flow a

Abstract. Biogeography relies on estimates of phylogeny and gene flow to test hypotheses. Established theory posits: (i) gene flow varies non-randomly with

Abstract. Population-scale long-read DNA sequencing (PLRS) is rapidly reshaping our understanding of genomic variation in humans and non-model species. In

For his project ‘De Oförtrutna’ (The Relentless), photographer Christer Björkman pictured Swedish scientists working in the spirit of Carl Linneaus, the botanist who created the modern taxonomic syste...

Post-glacial recolonisation of Fennoscandia created secondary contact zones in many species, offering opportunities to study how gene flow and selection contribute to their establishment and maintena....

Predicting the effect of a genetic mutation on fitness is a major challenge in evolutionary biology. This study uses fitness effects of a large collection of adaptive yeast mutants in multiple lab env...

Abstract. Nearly all modern studies that address evolutionary questions require consideration of the phylogenetic relationships among species. But what, ex

We examine two standard phylogenetic–biogeographic patterns and how these are interpreted by current ancestral-area algorithms. In the first pattern, a basal, paraphyletic grade is restricted to one ...

Genomic structural variation is an important component of genetic variation in natural populations. By assembling and analyzing multiple high-quality genomes within a species or clade, pangenomes capt...

Our understanding of speciation processes is constantly changing. Two important concepts that have influenced thinking over the long term are the isolation and the genic views of speciation. However,...

Host-parasite arms races facilitate rapid evolution and can fuel speciation. Cuculus cuckoos are deceptive egg mimics that exhibit a broad diversity of counterfeit egg phenotypes, representing host-ad...

AbstractSummary. PopGLen is a Snakemake workflow for performing population genomic analyses within a genotype-likelihood framework, integrating steps for r

Population size and dynamics fundamentally shape speciation by influencing genetic drift, founder events, and adaptive potential. Small populations may speciate rapidly due to stronger drift, whereas...

A new major version of ggplot2 has been released on CRAN. Find out what is new here.

Heredity - triangulaR: an R package for identifying AIMs and building triangle plots using SNP data from hybrid zones

In this study, we tested the hypothesis of the existence of a hybrid zone between two differentiated rock dove lineages, which may contribute significantly to their divergence. By analyzing newly gen...

A growing body of empirical research shows that interspecific gene flow is a widespread biological force that shapes evolutionary histories across the Tree of Life. Computational approaches designed t...
