Genomic inversions spanning many genes can persist for millions of years. This study of Trinidadian guppy populations reveals how both ecological conditions and mate choice help maintain this hidden l...

Abstract. Recombination diversifies offspring genomes and helps ensure chromosome segregation during meiosis. Mutation rates are elevated near crossovers d

Adaptation in protein-coding sequences can be detected from multiple sequence alignments across species or alternatively by leveraging polymorphism...

Sex chromosome evolution is among the most dynamic genomic innovations in vertebrates, yet why some lineages evolve XY while others evolve ZW remains unclear. Using chromosome-level genomes from 19 ge...

Hybridization between species can contribute to parallel adaptive events. However, the prevalence of introgression is rarely measured across multip...

Abstract. Predicting phenotypes from genetic variation is a central challenge in biology. Here, machine learning (ML) offers great promise, but its use is

One of the world's leading brain research centers is shifting away from fruit flies and toward a tiny, transparent fish. The goal: to understand how brains control the behavior of an animal or human.

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...

Abstract. Many long-standing questions in population genomics can now be addressed through comparative analyses and by leveraging the vast amount of genomi

Abstract. Many species of Colias butterflies show a female-limited colour polymorphism where the dominant Alba allele leads to white wings, faster developm

The repeated evolution of parental care is often accompanied by shifts in the neural circuits and hormonal pathways that regulate motivation and aggre…

Postzygotic reproductive isolation is often thought to accumulate as a byproduct of neutral divergence. Yet it frequently evolves rapidly, in line wit…

Evolution 2025 - the joint conference of the SSE, ASN, and SSB

Reconciliation algorithms infer the evolutionary history of individual gene trees given a species tree. Many reconciliation algorithms consider only duplication and loss events (and sometimes horizont...

Introgression between species can shape evolutionary trajectories in important ways. This study of the entire family of the colorful wood-warblers (Parulidae) uses whole-genome sequencing to reveal fr...

Replicated hybrid zones between ecotypes established over within shore environmental gradients provide an opportunity to study the genomic architecture of barriers to gene flow. The marine snail Litto...

Background While nuclear genome segregation is well characterized, mechanisms underlying mitochondrial partitioning remain partially obscure, even though its failure can cause developmental arrest or ...

Structural variants (SVs) are widespread in vertebrate genomes, yet their evolutionary dynamics remain poorly understood. Using 45 long-read de novo genome assemblies and pangenome tools, we analyze S...

The American Society of Naturalists (ASN) gives out student research awards (generally $2000 each) to support activities of our student members. We request that Student Research Award recipients provi...

The Cech Fellows Program is a paid, nine-week summer research experience empowering the next generation of scientific leaders.
