Cover image: The large capitula of the peat moss Sphagnum papillosum form thick carpets in nutrient-poor fens, such as this one in Orivesi, Finland. Their large size allows them to hold water and resist desiccation during seasonal droughts, which are becoming increasingly common. Image by Nicola Kokkonen. For full details see pages 1210–1224.
