Response Of CO2 Exchange In A Tussock Tundra Ecosystem To Permafrost Thaw And Thermokarst Development
Journal: Journal Of Geophysical Research: Biogeosciences, Volume 114 (G4): n/a-n/a (2009). DOI: 10.1029/2008jg000901 Sites: US-EML
Climate change in high latitudes can lead to permafrost thaw, which in ice-rich soils can result in ground subsidence, or thermokarst. In interior Alaska, we examined seasonal and annual ecosystem CO2exchange using static and automatic chamber measurements in three areas of a moist acidic tundra ecosystem undergoing varying …

Plant Species Composition And Productivity Following Permafrost Thaw And Thermokarst In Alaskan Tundra
Journal: Ecosystems, Volume 10 (2): 280-292 (2007). DOI: 10.1007/s10021-007-9024-0 Sites: US-EML
Climate warming is expected to have a large impact on plant species composition and productivity in northern latitude ecosystems. Warming can affect vegetation communities directly through temperature effects on plant growth and indirectly through alteration of soil nutrient availability. In addition, warming can cause permafrost …
