Complexity of biological forms has fascinated humankind over the years. Different species of plants have different leaf shapes. Have you ever wondered why it is so? Why does this shape diversity exist? Plants can change their ...
In a large-scale study with almost 400 partners, researchers worldwide have collected data on tree species, to which scientists from Bayreuth have contributed their knowledge about the Kilimanjaro region. The study, which ...
