Don) Oerst. ex D.P. Little] # in southeast Alaska due to warming, emphasize a need to investigate nonstationary climate response # of Alaskan coastal forests to warming in other tree species. # Comparison of annual tree growth in mountain hemlock [Tsuga mertensiana (Bong.)Carriere] # to mean monthly temperature and precipitation data from Sitka, Alaska, from A.D. 1830s to 1990s # along an elevational transect reveals nonstationarity in tree growth response to climate # that suggests an ongoing biome shift. We observe a marked weakening in the positive relationship # between annual growth and warmer growth season temperatures at low-elevation hemlock sites, # and a concurrent increase in growth and sensitivity at higher elevations coupled with increased # correlation between growth and April precipitation at all sites along our transects. As previously # observed with yellow cedar, the mechanism of the hemlock biome shift may be due to an increased # susceptibility of roots to damage from late frosts resulting from earlier seasonal loss of protective snowpack. #-------------------- # Funding_Agency # Funding_Agency_Name: # Grant: #-------------------- # Site_Information # Site_Name: Juneau Mountain # Location: Alaska # Northernmost_Latitude: 58.3 # Southernmost_Latitude: 58.3 # Easternmost_Longitude: -134.3833 # Westernmost_Longitude: -134.3833 # Elevation_m: 540 #-------------------- # Data_Collection # Collection_Name: AK130 # First_Year: 1557 # Last_Year: 1999 # Time_Unit: CE # Core_Length_m: # Parameter_Keywords: ring width # Notes: #-------------------- # Species # Species_Name: Tsuga mertensiana (Bong.)
