    The Aquilegia genome provides insight into adaptive radiation and reveals an extraordinarily polymorphic chromosome with a unique history

    Danièle L Filiault et al.
    The evolution columbine genus involved frequent mixing between incipient species, and one chromosome appears to have taken its own path.

    Genome-wide mapping in a house mouse hybrid zone reveals hybrid sterility loci and Dobzhansky-Muller interactions

    Leslie M Turner, Bettina Harr
    The genomic regions that cause male hybrids between house mouse subspecies to have low fertility have been identified.

    Natural selection and repeated patterns of molecular evolution following allopatric divergence

    Yibo Dong et al.
    The genomic architecture of allopatric species is a mosaic of many conserved genes and a few adaptive ones, reflecting balance between conservation of ancestral functions and evolution of new features.

    Genome rearrangements and pervasive meiotic drive cause hybrid infertility in fission yeast

    Sarah E Zanders et al.
    Rapid acquisition of chromosome rearrangements, together with independently acting transmission distorter alleles on each chromosome, drive near complete sterility in fission yeast hybrids.

    A complete toolset for the study of Ustilago bromivora and Brachypodium sp. as a fungal-temperate grass pathosystem

    Franziska Rabe et al.
    The establishment of Ustilago bromivora and Brachypodium as a biotrophic model system provides the foundation for studying new aspects of plant-pathogen interactions and for answering questions about fungal sex and speciation.

    The Natural History of Model Organisms: An organismal perspective on C. intestinalis development, origins and diversification

    Matthew J Kourakis, William C Smith
    The life cycle and morphology of the sea squirt Ciona intestinalis shed light on vertebrate evolution.

    The Natural History of Model Organisms: Advancing biology through a deeper understanding of zebrafish ecology and evolution

    David M Parichy
    The zebrafish is a premier model organism for biomedical research, with a rich array of tools and genomic resources, and combining these with a fuller appreciation of wild zebrafish ecology could greatly extend its utility in biological research.
