Rosemary Sherriff published “Warming drives a front of white spruce recruitment near western treeline, Alaska” with National Park Service collaborators in Global Change Biology. Warming has increased productivity near the boreal forest margin in Alaska. However, the effects on seedling recruitment has received little attention, in spite of forecasted forest expansion. The study of 95 sites across a longitudinal gradient in southwest Alaska shows a differential relationship between longitude and life-stage (seedling, sapling, tree) abundance that suggests a moving front of white spruce establishment through time, driven by changes in environmental conditions near the species’ range limit.
