    Adaptability of trees persists after millions of years of climate change

    Seven of the most common forest trees in Europe have been shown to be able to shelter their genetic diversity from major shifts in environmental conditions. This is despite their ranges having shrunk and the number of trees having fallen sharply during ice age cycles. These are the findings of a study jointly led by Uppsala and Helsinki Universities, published in Nature Communications.

    Invisible fungi revealed by their genetic material

    How can new life forms that we cannot see be discovered? Using a novel method based on looking for DNA in soil samples, researchers at Uppsala University have revealed the existence of two hitherto unknown, but very common fungus species. They are thought to perform a key function in the ecosystem, but their exact role remains to be clarified. The study is published in the journal IMA Fungus.
