The response of forest plant regeneration to temperature variation along a latitudinal gradient
Background and Aims The response of forest herb regeneration from seed to temperature variations across latitudes was experimentally assessed in order to forecast the likely response of understorey community dynamics to climate warming. Methods Seeds of two characteristic forest plants ( Anemone nem...
