  • How beetle larvae thrive on carrion
    on October 15, 2018 at 7:06 pm

    The burying beetle Nicrophorus vespilloides buries the cadavers of small animals to use them as a food source for its offspring. However, the carcass is susceptible to microbial decomposition. Researchers show that the beetles replace harmful microorganisms with their own beneficial gut symbionts, thus turning a carcass into a nursery with a microbial community that even promotes larval growth. […]

  • Unravelling the genetics of fungal fratricide
    on October 15, 2018 at 3:35 pm

    Selfish genes are genes that are passed on to the next generation but confer no advantage on the individual as a whole, and may sometimes be harmful. Researchers have, for the first time, sequenced (or charted) two selfish genes in the fungus Neurospora intermedia that cause fungal spores to kill their siblings. Unexpectedly, the genes were not related to each other, perhaps indicating that selfish genes are more common than previously thought. […]

  • Tropical frogs found to coexist with deadly fungus
    on October 3, 2018 at 2:27 pm

    In 2004, the frogs of El Copé, Panama, began dying by the thousands. The culprit: the deadly chytrid fungus Batrachochytrium dendrobatidis. Within months, roughly half of native frog species there went locally extinct. A new study suggests that frogs remaining in El Copé developed the ability to coexist with chytrid fungus due to ecological and/or evolutionary changes. The results could mean good news for other areas hit hard by chytrid fungus. […]
