The paper investigates how phenotypic switching strategies affect expansion speed in spatial populations, showing optimal switching rates and the impact of adaptation lags and spatial structure.

The paper examines genome size variation in Rorippa indica, finding that larger genomes are adaptive in tropical environments due to increased reproductive output despite slower growth.

This study investigates the evolution of burrowing behavior in Lagomorphs, finding it evolved multiple times independently and correlates with sociality and higher fecundity.

This study generates chromosome-scale genome assemblies of germline restricted chromosomes (GRCs) in fungus gnats and finds they evolve dynamically with gene-rich content under strong purifying selection.

The paper analyzes gene expression across eight tissues in Daphnia pulex and investigates selection pressures on genes in different tissues, identifying novel evolutionary patterns.

This study identifies a fourth ancestral component in Dravidian-speaking tribes, suggesting a Proto-Dravidian ancestry originating around 4,400 years ago, distinct from other known sources.

This study analyzes DUES distribution and functional associations in 177 genomes, identifying novel DUS dialects and showing functional divergence between Neisseriaceae and Pasteurellaceae.

This study examines genomic features of Anolis lizards to identify structural rearrangements, repeat elements, and selection signatures linked to phenotypic diversity.

The paper identifies highly recurrent multi-nucleotide mutations in SARS-CoV-2 and shows they are linked to transcription regulatory sequences, affecting computational evolutionary biology analyses.

The paper develops a mathematical model to quantify the fitness benefits of phagocytosis in evolutionary contexts and identifies conditions under which it provides an advantage.

This study examines DNA methylation and genetic imprinting in water lily endosperm, finding maternally-expressed imprinted genes and differential DNA methylation are ancestral traits.

This study investigates how metal preference in SodFM enzymes evolves through redox modulation by the secondary coordination sphere, revealing a link between oxidation state and catalytic metal preference.

The paper shows that the London Underground Mosquito adapted to human environments aboveground in the Middle East over 1000 years, not recently underground in London.

This study shows that X chromosome dosage compensation mechanisms evolved independently in two nematode lineages through parallel evolution of SMC complexes.

The paper identifies programmed DNA elimination in three Caenorhabditis species, showing it was present in their last common ancestor and later lost in some lineages.

The paper describes two new Telonemia species, highlights morphological and phylogenetic differences, and provides insights into their biology and evolutionary significance.

The paper tests how environmental stress affects competitive asymmetry in two hybrid darter species, showing that stress amplifies competition and leads to different hybrid zone outcomes.

This paper reanalyzes evolutionary rate-time relationships, showing negative scaling is inevitable and often misinterpreted, with time variation explaining most variation across datasets.

The paper uses a stochastic model to show how coevolution and extinction rates shape pollination network structure and species persistence on islands.
