Shifts in Arctic vegetation and associated feedbacks under climate change
Climate warming has led to changes in the composition, density and distribution of Arctic vegetation in recent decades1–4. These changes cause multiple opposing feedbacks between the biosphere and atmosphere5–9, the relative magnitudes of which will have globally significant consequences but are unknown at a pan-Arctic scale10. The precise nature of Arctic vegetation change under future warming...
متن کاملVegetation ecotone dynamics in Southwest Alaska during the Late Quaternary
To examine Late Quaternary vegetation change across the modern vegetation gradient from continuous boreal forest (central Alaska) to Betula shrub tundra (Bristol Bay region), pollen records from Idavain and Snipe Lakes are described and compared to those of four other sites in southwest Alaska. Major features of the vegetation history at Idavain Lake include herb-dominated tundra (ca. 14}12 ka ...
