The paper analyzes the genomic diversity of Wolbachia strains and their plasmids in Aedes albopictus, revealing evolutionary patterns and structural variation driven by environmental factors.

The paper uses ancient metagenomics to characterize subglacial microbiomes, showing they split into two clusters based on oxygen availability and redox conditions.

The paper introduces a fitness landscape model to predict hybrid fitness across varying ploidy and lineage complexity, validated using maize and rye hybrid data.

This study investigates the long-term benefits of hybridization by modeling genetic variation and heterosis, finding that outcomes depend on epistasis variance rather than heterosis itself.
