This paper introduces a graph-theoretic framework to uniquely represent cross-gene branch identities in phylogenomic data, ensuring consistent and auditable comparative analyses.

The paper shows that fitness variation across drug environments in yeast is organized by a low-dimensional phenotypic structure, revealing modular phenotypic modules that constrain adaptive mutations.

This study shows that genetic variation persists under intense directional selection in Drosophila and can be rapidly redeployed when selection reverses, suggesting balancing-selection maintains this variation.

The paper identifies a novel class of resistance genes in Myrtaceae, TNJ, characterized by Jacalin domains replacing LRRs, and suggests their role in pathogen recognition.

The paper investigates genomic adaptations in thermophilic Chaetomiaceae fungi, finding higher substitution rates and stronger purifying selection compared to mesophiles.

This study integrates genomics and transcriptomics to identify molecular changes in vampire bats adapted to blood-feeding, revealing shifts in gene expression and function across multiple biological pathways.

The paper compares the distribution of young de novo proteins, old canonical proteins, and randomized sequences in sequence space using k-mer-based distances, finding distinct patterns and potential pathways between classes.

This paper identifies recurrent triploidy in cultivated enset, showing it increases yield and is selected by farmers.

This paper develops theory to explain how host-symbiont coevolution leads to either cooperation or exploitation, depending on population-genetic factors.

The paper identifies mitonuclear co-introgression in red-backed voles, showing adaptive mitochondrial introgression and avoidance of mitonuclear incompatibilities through co-introgression of nuclear-encoded mitochondrial genes.

The paper describes a new parasitic nucleariid with a flagellated life cycle, placing it as a basal lineage within Holomycota and revising evolutionary hypotheses.

The paper analyzes oxygen-sensing regulatory architecture across 239 mammalian species, finding it tracks evolutionary transitions, ecological strategies, and cancer resistance.

The paper shows that environmental changes influence the complexity of mating displays and their persistence in changing climates.

This study measures mutation rate and spectrum plasticity in Ostreococcus tauri under different environmental conditions, finding significant variation in SNM rates and spectra.

The paper simulates secondary contact between populations to show how search costs and pleiotropy affect mating trait differentiation and species persistence.

The paper identifies a localized introgressed haplotype in a great tit that retains distinct ancestry despite genome-wide homogenization, linking it to plumage pigmentation.

This study identifies four independent origins of hummingbird syndrome in Penstemon and finds rapid floral trait convergence without stepwise modification or adaptive introgression.

The paper models how recombination-associated mutation affects the evolution of recombination rates, finding that mutation near crossovers reduces the advantage of recombination.

The paper identifies a recombination event within a non-recombining sex chromosome in blackspotted sticklebacks, challenging the notion that recombination suppression is irreversible.

The paper assesses the Z:A ratio as a genomic indicator of sexual selection in lekking birds, finding it influenced by demographic history and hybridization rather than solely sexual selection.
