This paper develops a theoretical framework to explain how ecological interactions between microbes influence the distribution of fitness effects of mutations.

This study examines how mate-finding Allee effects influence evolutionary rescue in populations below their Allee threshold, showing that mate limitation can impede rescue and alter optimal strategies.

The paper uses a genome language model to analyze plant Y chromosomes from Silene and Humulus, identifying shared genomic features and evolutionary patterns despite structural divergence.

This study identifies shared genetic adaptation signals in mesopelagic lanternfishes to climate change using whole-genome sequencing across multiple oceanic regions.

LINGUINE improves ancestral linkage group inference by using orthogroups and a Hidden Markov Model to handle gene loss and paralogy, outperforming existing methods in nematodes and clitellate annelids.

The paper tracks the evolution of Avian Influenza H5N1 genotype EA-2024-DI across three epidemic waves, showing changes in transmission patterns and increased mammalian host adaptation.

This study uses genomic data to analyze the evolutionary history and demographic processes of three Ara macaw species, identifying genetic structure and adaptation signals across different biomes.

The paper shows that intermediate abundance maximizes speciation probability under limited dispersal, supported by empirical analysis of Hawaiian arthropod data.

This study examines local adaptation in Arabidopsis thaliana across East African sky-islands, finding limited parallel adaptation and evidence of divergent selection based on climate.

The paper simulates coevolution of sleep/wake patterns in a predator/prey system, revealing cyclic temporal niche pursuit dynamics across evolutionary timescales.

This study identifies miRNAs involved in transgenerational thermal plasticity in coral reef fish, showing that parental temperature exposure affects offspring miRNA-mRNA networks differently based on parent type.

The paper shows that molecular evolution rates vary with timescale, affecting evolutionary history inferences, and is analogous to the Sadler effect in geology.

The paper identifies an X-linked sex determination mechanism in cannabis and hop, showing that an X-linked gene involved in ethylene biosynthesis controls female inflorescence development, while the Y chromosome lacks clear sex-determining genes.

The paper compares olfactory coding in three drosophilid species to assess conservation of peripheral detection and behavioral valence across evolutionary divergent subgenera.

This study shows that parental infection in Drosophila melanogaster improves offspring survival and disease resistance to both homologous and heterologous pathogens without measurable costs.

The paper develops a mathematical model based on danger theory to show that cost-based immune activation favors avirulence in microbes, proposing the danger hypothesis of virulence evolution.

This study analyzes the genomic evolution and zoonotic potential of swine-origin influenza A viruses in Spain, identifying novel reassortants and highlighting human-swine viral transmission.

The paper reconstructs the evolutionary history of amylase duplications in primates, showing convergent expression patterns and functional divergence across species.

The paper shows climate factors predict wMel Wolbachia frequency globally, but genomic variation reflects a recent incomplete cytoplasmic sweep rather than local adaptation.

The paper investigates the evolutionary loss of prfB autoregulation in Pseudomonas fluorescens SBW25, finding that compensatory mutations enable this loss without significant fitness cost.
