This paper introduces a Bayesian method to estimate stratigraphic intervals and their co-occurrence, using empirical examples and a Julia package for implementation.

This study investigates how incomplete purifying selection affects viral phylogenies and phylodynamic inference, finding little bias in key epidemiological estimates despite mutation distribution shifts.

This study shows that heat shock induces transgenerational gene expression changes and beneficial phenotypes more strongly in arid Drosophila populations than temperate ones.

The paper characterizes the avian pallium's cell types and evolution using single-cell and spatial transcriptomics, revealing conserved and divergent features across amniotes.

This study resolves the phylogenetic position of Njordarchaeales and Panguiarchaeales, placing them as a new class Njordarchaeia within Asgard archaea and identifying Panguiarchaeum as a metabolically reduced, potentially symbiotic lineage.

The paper examines how speciation completion rates affect macroevolutionary diversification by comparing standard birth-death models with a protracted birth-death model.

This study investigates the genetic and anatomical basis of olfaction in dogs and wild canids, finding no evidence of human-directed selection for enhanced olfaction in domestic dogs.

The paper assesses mutation fitness effects in two Arabidopsis thaliana ecotypes under natural conditions and finds beneficial mutations accumulate, with the poorly adapted ecotype showing higher mutation variance.

The paper identifies genomic loci underlying adaptive peaks in Antirrhinum by analyzing 18 populations and finding two partitions associated with hybrid incompatibility and eco-adaptation.

This study examines how introgression affects recombination patterns in yeast by analyzing crossover and non-crossover rates in crosses with and without introgression.

This study proposes that aposematic signals may have evolved through sexual selection, leading to increased predation pressure and the eventual development of anti-predator defenses.

This study shows that kin discrimination in partner choice increases overall helping behavior compared to indiscriminate helping.

The study examines how light environment and seasonal changes affect chromophore usage and opsin expression in red shiners, finding a temperature-dependent trade-off and limited opsin variation.

The paper shows that BORIS is present in birds but frequently degraded in neognathous birds, with independent decay events affecting the coding sequence and linked to evolutionary changes.

This study investigates genetic and environmental factors driving urban phenotypic divergence in great tits using a common garden experiment, finding that genetic and individual differences explain most trait variation, while urban behavioral differences are more plastic.

This study shows that low sterol diets in Drosophila melanogaster females lead to gut dysfunction and reduced lifespan.

This paper uses a large language model to extract flower color data from Flora descriptions, expanding the TRY Plant Trait Database and linking it with environmental data to analyze flower color-environment relationships.

This paper investigates the consequences of gene tree-species tree mismatch in phylogenetic regression and finds high false positive rates when trees are mismatched.

The paper identifies lineage-specific expansions of Class-A GPCRs in Lophotrochozoa, linking them to habitat adaptations and chemosensory functions.

The paper shows that mutations in protein binding domains, combined with regulatory divergence, determine the fate of gene duplicates in a protein interaction network.
