In the light of on-going climate change, climate sensitivity studies of these unique trees are essential to predict vegetation dynamics and potential northward expansion of boreal forest tree species into tundra. Here we studied one of the northernmost Larix Mill. trees and Betula nana L. shrubs (72°N) from the Siberian tundra for the common period 1980-2017. We took advantage of the discovery of a single cohort of prostrate Larix trees within a tundra ecosystem, i.e., ca. 60 km northwards from the northern treeline, and compared climate-growth relationships of the two species. Both woody plants were sensitive to the July temperature, however this relationship was stable across the entire study period (1980-2017) only for Betulanana chronology. Additionally, radial growth of Larix trees became negatively correlated to temperatures during the previous summer. In recent period moisture sensitivity between Larix trees and Betula nana shrubs was contrasting, with generally wetter soil conditions favoring Larix trees growth and dryer conditions promoting Betula nana growth. Our study indicates that Larix trees radial growth in recent years is more sensitive to moisture than to summer air temperatures, whereas temperature sensitivity of Betulanana shrub is stable over time. We provide first detailed insight into the annual resolution on Larix tree growth sensitivity to climate in the heart of the tundra. The potentially higher Betulanana shrub resistance to warmer and drier climate versus Larix trees on a tundra revealed in our study needs to be further examined across habitats of various soil, moisture and permafrost status. #-------------------- # Funding_Agency # Funding_Agency_Name: European Union - F7P INTERACT # Grant: 262693 #-------------------- # Funding_Agency # Funding_Agency_Name: European Space Agency, Climate Change Initiative # Grant: 4000l3376l/2l/I-NB #-------------------- # Funding_Agency # Funding_Agency_Name: Helmholtz Association Climate Initiative REKLIM # Grant: #-------------------- # Site_Information # Site_Name: Kurungnakh Island, Lena River Delta # Location: Russia # Northernmost_Latitude: 72.283333 # Southernmost_Latitude: 72.283333 # Easternmost_Longitude: 126.133333 # Westernmost_Longitude: 126.133333 # Elevation_m: 50 #-------------------- # Data_Collection # Collection_Name: RUS393 # First_Year: 1934 # Last_Year: 2017 # Time_Unit: CE # Core_Length_m: # Parameter_Keywords: width # Notes: #-------------------- # Species # Species_Name: Betula spp. L. # Common_Name: birch # Tree_Species_Code: BESP #-------------------- # Variables # # PaST_Thesaurus_Download_Resource: https://www.ncei.noaa.gov/access/paleo-search/skos/past-thesaurus.rdf # PaST_Thesaurus_Download_Description: Paleoenvironmental Standard Terms (PaST) Thesaurus terms, definitions, and relationships in SKOS format. # # Data variables follow that are preceded by '##' in columns one and two. # Variables format: shortname-tab-var components: what, material, error, units, seasonality, data type, detail, method, C or N for Character or Numeric data) # ## age_CE age,,,year Common Era,,tree ring,,,N, ## trsgi tree ring standardized growth index,,,,,tree ring,composited,standard chronology method,N, ## numsamp number of samples,,,count,,tree ring,,,N, #--------------------- # Data: # Missing_Values: NA age_CE trsgi numsamp 1934 1.386 1 1935 0.975 1 1936 0.953 1 1937 1.82 1 1938 1.456 1 1939 1.227 1 1940 0.79 1 1941 0.894 1 1942 0.66 1 1943 0.648 1 1944 0.423 1 1945 0.214 1 1946 0.625 1 1947 0.412 1 1948 0.44 1 1949 1.227 1 1950 0.566 1 1951 1.826 1 1952 1.605 1 1953 1.087 1 1954 0.79 1 1955 0.42 1 1956 1.307 1 1957 0.788 1 1958 0.959 1 1959 0.491 1 1960 0.958 1 1961 1.45 1 1962 2.165 1 1963 1.661 2 1964 0.891 2 1965 0.88 2 1966 0.824 2 1967 1.335 2 1968 0.449 2 1969 1.473 2 1970 1.259 3 1971 1.568 3 1972 1.026 6 1973 1.255 6 1974 0.723 8 1975 1.153 8 1976 0.972 8 1977 0.971 9 1978 0.968 9 1979 0.702 9 1980 0.731 11 1981 0.967 13 1982 1.109 14 1983 1.003 16 1984 0.905 17 1985 0.918 18 1986 0.917 21 1987 0.867 22 1988 0.892 23 1989 0.744 26 1990 1.029 28 1991 1.194 28 1992 1.079 28 1993 0.857 29 1994 1.025 30 1995 1.029 30 1996 0.809 32 1997 0.955 32 1998 0.992 32 1999 0.982 32 2000 0.437 33 2001 1.437 34 2002 0.918 34 2003 0.971 34 2004 0.997 34 2005 1.12 35 2006 0.975 35 2007 0.698 36 2008 0.89 37 2009 0.95 37 2010 1.172 36 2011 0.984 36 2012 1.084 36 2013 1.102 35 2014 0.983 34 2015 0.758 33 2016 0.812 31 2017 0.868 28
