Cutting-edge DNA metabarcoding technology can help speed up and improve the monitoring process, according to a new study. […]

  • Deer prefer native plants leaving lasting damage on forests
    on October 6, 2017 at 6:21 pm

    When rampant white-tailed deer graze in forests, they prefer to eat native plants over certain unpalatable invasive plants, such as garlic mustard and Japanese stiltgrass. These eating habits lower native plant diversity and abundance, while increasing the proportion of plant communities made up of non-native species, according to a new study. […]

  • Carbon feedback from forest soils to accelerate global warming
    on October 5, 2017 at 6:18 pm

    After 26 years, the world's longest-running experiment to discover how warming temperatures affect forest soils has revealed a surprising, cyclical response: Soil warming stimulates periods of abundant carbon release from the soil to the atmosphere alternating with periods of no detectable loss in soil carbon stores. The study indicates that in a warming world, a self-reinforcing and perhaps uncontrollable carbon feedback will occur between forest soils and the climate system, accelerating global warming. […]

  • Tropical diversity takes root in relationships between fungi and seeds
    on October 2, 2017 at 8:12 pm

    Scientists in Panama exposed a key to understanding tropical tree diversity by studying how fungi interact with seeds that linger in the ground. Despite a smorgasbord of species available to choose from, tropical fungi and seeds are picky about associating with one another. Early pairings with a particular fungus may influence whether a seed survives and also may help explain how tropical forests remain so diverse. […]
