Role of climate and herbivory on native and alien conifer seedling recruitment at and above the Fennoscandian tree line
Abstract Questions We investigated the importance of climate and herbivory on native and alien conifer colonization of the birch‐dominated Fennoscandian tree line by addressing the following questions: (a) are tree line and tundra habitats similarly suitable for conifer seedling recruitment; (b) do...
