Journal ArticleDOI
Recent change of Arctic tundra ecosystems from a net carbon dioxide sink to a source
Walter C. Oechel,Steven J. Hastings,George L. Vourlitis,M. A. Jenkins,George H. Riechers,Nancy Grulke +5 more
TL;DR: This article found that the tundra on the North Slope of Alaska has indeed become a source of carbon dioxide to the atmosphere and that this change coincides with recent warming in the Arctic, whether this is due to increases in greenhouse gas concentrations in the atmosphere or to some other cause.
Journal ArticleDOI
Tree and forest functioning in response to global warming
TL;DR: This review focuses on tree and forest responses at boreal and temperate latitudes, ranging from the cellular to the ecosystem level, and management is critical for a positive response of forest growth to a warmer climate.
Journal ArticleDOI
Acclimation of ecosystem CO2 exchange in the Alaskan Arctic in response to decadal climate warming
Walter C. Oechel,George L. Vourlitis,George L. Vourlitis,Steven J. Hastings,Rommel C. Zulueta,Larry D. Hinzman,Douglas L. Kane +6 more
TL;DR: Summer CO2 flux data for two Arctic ecosystems from 1960 to the end of 1998 shows that a return to summer sink activity has come during the warmest and driest period observed over the past four decades, and indicates a previously undemonstrated capacity for ecosystems to metabolically adjust to long-term changes in climate.
Journal ArticleDOI
Transient nature of CO 2 fertilization in Arctic tundra
Walter C. Oechel,Sid Cowles,Nancy Grulke,Steven J. Hastings,Bill Lawrence,Tom Prudhomme,George H. Riechers,Boyd R. Strain,David T. Tissue,George L. Vourlitis +9 more
TL;DR: In this paper, the authors present results of an in situ experiment on the response of an intact native ecosystem to elevated CO2 in a tussock tundra at Toolik Lake, Alaska, which was enclosed in greenhouses in which the CO2 level, moisture and temperature could be controlled.
