This study develops a unified Wright-Fisher model to analyze mutation fate on Y chromosomes and autosomes, showing overdominant mutations are more likely to fix on Y chromosomes due to segregation time effects.

This study shows that biparental inheritance of endosymbionts during host-symbiont co-evolution leads to evolutionary conflict, which can be resolved through host regulation mechanisms, and that sexual reproduction may have emerged early in eukaryogenesis.

The paper estimates mutation load in stickleback populations and finds complex hitchhiking patterns with no overall accumulation of deleterious alleles.

The study investigates diversifying selection on the missing-self regulator CFH in bank voles, finding evidence of positive selection in its Borrelia-interacting domain and coevolution with pathogens.

This study shows that habitat reconstruction and genome mutation can equally increase bacterial fitness through experimental evolution and active learning.

This study examines how pleiotropy and local adaptation interact in Helianthus argophyllus by analyzing transcriptomic data and identifying gene expression patterns associated with environmental adaptation.

This study shows segmental copy number amplifications are more stable than aneuploidies when selection pressure is removed, with aneuploidies reverting quickly and losing fitness.

This study shows a tradeoff between heat shock recovery and growth at elevated temperatures in Methylobacterium strains.

The paper presents a simulation model demonstrating nonrandom, non-Lamarckian mutation in evolution using an estimation-of-distribution algorithm, highlighting the role of internal genomic information integration.

This study shows that unilateral cross-feeding interactions constrain adaptive evolution in both producer and consumer microbes, even when the producer experiences no direct fitness effects.

The paper investigates non-ergodicity in ecological and evolutionary dynamics through case studies, showing how stochasticity affects population growth, genotype fitness, and cooperation evolution.

This paper investigates how background selection affects complex trait evolution under different phenotypic selection models, showing that genetic variance changes depend on the relationship between phenotype and fitness.

The paper shows that a few individuals with large haploblocks of adaptive alleles drove rapid freshwater adaptation in Threespine Stickleback, with inbreeding reducing genetic load.

This study shows that the microalga Haematococcus lacustris uses both r and K reproductive strategies throughout its life cycle, challenging the idea that species only use one strategy.

This study shows that genome architecture and gene-gene interactions influence the repeatability of polygenic adaptation in two copepod species with different chromosome numbers.

This study shows inbreeding depression persists even without genetic variation, suggesting epigenetic factors may contribute to its persistence.

WINDEX improves detection of positive selective sweeps by integrating site- and window-based statistics in population genetic data, showing improved localization and genome-wide estimates of selective pressures.

AEGIS models life history trait evolution using individual-based simulations to test ecological and demographic factors' impacts on traits like reproduction and lifespan.

This study shows that thermal adaptation across yeast species involves convergent changes in conserved regulatory networks, despite divergent phenotypic outcomes.

This study uses simulations to show that beneficial microbes, rather than parasites, drive the evolution and maintenance of adaptive immunity by reducing selection pressure on innate immunity.

This study evolves a plant RNA virus in age-diverse host populations and finds that host age structure drives virulence evolution by shaping disease progression, severity, and viral load.

The paper shows capsule exchange in Klebsiella pneumoniae has minimal fitness costs and preserves virulence traits across genetic backgrounds, suggesting plug-and-play dynamics in capsule loci.
