Accumulation of carbon and nitrogen in vegetation and soils of deglaciated area in Ellesmere Island, high-Arctic Canada

摘要: Abstract The amount of biomass, carbon (C), and nitrogen (N) in vegetation soil were measured at two spatial scales the high Arctic. At scale proglacial landscape, C N aboveground belowground parts vegetation, surface litter, significantly affected by habitat (moraines vs hummocks), relative age terrain after deglaciation, and/or vegetation. another scale, we focused on mudboils as an agent local disturbance glacier foreland. biomass biological crust, generally increased with stage mudboils' inactivation. Biomass, C, litter greater moraine than hummock, whereas those crust hummock. Principal component analysis identified pathways, xeric mesic ones moraines hummocks, respectively, accumulation both scales. These results suggested that was not linearly related to time since deglaciation moisture condition, mudboil activity locally important.
