One whale’s waste is an ocean organism’s treasureThe nutrients in the ocean are not evenly distributed. Resources tend to be rich around coastlines and near the poles, and are often poorer in the open ocean and the tropics. A new study has explored how urine from migrating baleen whales is a significant way that nitrogen and other nutrients are circulated in the oceans. Joe Roman is a conservation biologist at the University of Vermont. He led the research, published in the journal Nature Communications. The underground economy: Fungi and plants trade have a network under our feetScientists have used a custom robot to track the growth of a complex underground supply-chain network that forms between more than 80 per cent of the plant species on Earth and symbiotic fungus. This allowed them to trace the flow of carbon and nutrients across this network,  that draws about 13 billion tons of carbon dioxide into the soil each year.
