Palaeolimnological techniques can be used to provide analogues of how such changes in tree-line advance and subsequent retreat affected lake ecosystems in the past. A Holocene sediment core taken from Kharinei Lake (Russia) was dated radiometrically and used for multi-proxy analyses with the aim of determining how climate and tree-line dynamics affected the productivity, community structure, carbon cycling and light regime in the lake. Pollen and macrofossil analyses were used to determine the dates of the arrival and retreat of birch and spruce forest. C:N ratios and percent loss-on-ignition were used to infer past changes in sediment organic matter. Visible-near-infrared spectroscopy and diatom analysis were used to infer past changes in lake-water carbon. Algal pigments and aquatic macrophytes were used to determine changes in lake productivity and light. Chironomids together with remains of the aquatic flora and fauna were used to provide information on past July temperature and continentality. Lake sedimentation was initiated shortly before 11,000 cal. years BP, when both chironomid- and pollen-inferred temperature reconstructions suggest higher summer temperatures than present, between 1 and 2°C warmer, and lake productivity was relatively high. A few trees were already present at this time. The spruce forest expanded at 8,000 cal. year BP remaining in the vicinity of the lake until 3,500 cal. year BP. This period coincided with a high concentration of organic material in the water column, and relatively high benthic productivity, as indicated by a high benthic: planktonic diatom ratio. After tree-line retreat, the optical transparency of the lake increased, and it became more open and exposed, and was thus subject to greater water-column mixing resulting in a higher abundance of diatom phytoplankton, especially heavily silicified Aulocoseira species. The colder climate resulted in a shorter ice-free period, the lake was less productive and there was a loss of aquatic macrophytes. Increased wind-induced mixing following forest retreat had a greater influence on the lake ecosystem than the effects of decreasing organic matter concentration and increased light penetration. #------------------ # Publication # Authors: Kaufman, D., N.

We present a global compilation of quality-controlled, published, temperature-sensitive proxy records extending back 12,000 years through the Holocene. Data were compiled from 679 sites where time series cover at least 4000 years, are resolved at sub-millennial scale (median spacing of 400 years or finer) and have at least one age control point every 3000 years, with cut-off values slackened in data-sparse regions. The data derive from lake sediment (51%), marine sediment (31%), peat (11%), glacier ice (3%), and other natural archives. The database contains 1319 records, including 157 from the Southern Hemisphere. The multi-proxy database comprises paleotemperature time series based on ecological assemblages, as well as biophysical and geochemical indicators that reflect mean annual or seasonal temperatures, as encoded in the database. This database can be used to reconstruct the spatiotemporal evolution of Holocene temperature at global to regional scales, and is publicly available in Linked Paleo Data (LiPD) format. #------------------ # Funding_Agency # Funding_Agency_Name: # Grant: #------------------ # Site_Information # Site_Name: Kharinei # Location: Europe>Eastern Europe>Russian Federation # Country: Russia # Northernmost_Latitude: 67.3628 # Southernmost_Latitude: 67.3628 # Easternmost_Longitude: 62.7507 # Westernmost_Longitude: 62.7507 # Elevation: 108 #------------------ # Data_Collection # Collection_Name: Kharinei.Jones.2011 # Earliest_Year: 11502.69 # Most_Recent_Year: -53.246 # Time_Unit: cal yr BP # Core_Length: # Notes: #------------------ # Species # Species_Name: # Species_Code: # Common_Name: #------------------ # Chronology_Information # Chronology: # OriginalDateID depth_top depth_bottom age_type age uncertainty_old uncertainty_young Include material # nan 0.0 nan Core top -55.0 0.0 0.0 Y cored in April 2007 # nan 0.25 nan Pb210-Lead -53.0 -51.0 -55.0 Y modelled from Pb-210 data # nan 0.75 nan Pb210-Lead -40.0 -37.0 -43.0 Y modelled from Pb-210 data # nan 1.25 nan Pb210-Lead -13.0 -7.0 -19.0 Y modelled from Pb-210 data # nan 1.75 nan Pb210-Lead 4.0 14.0 -6.0 Y modelled from Pb-210 data # nan 2.25 nan Pb210-Lead 26.0 44.0 8.0 Y modelled from Pb-210 data # nan 2.75 nan Pb210-Lead 76.0 104.0 48.0 Y modelled from Pb-210 data # SUERC-21513 20.0 21.0 age14C 2663.0 2700.0 2626.0 N Bulk sediment # SUERC-21516 30.0 31.0 age14C 2256.0 2293.0 2219.0 N Bulk sediment # SUERC-17505 40.0 41.0 age14C 2411.0 2448.0 2374.0 N Bulk sediment # SUERC-21517 72.0 73.0 age14C 4640.0 4678.0 4602.0 N Bulk sediment # SUERC-21518 100.0 101.0 age14C 3571.0 3611.0 3531.0 N Bulk sediment # SUERC-17506 128.0 129.0 age14C 5555.0 5593.0 5517.0 N Bulk sediment # SUERC-21519 152.0 153.0 age14C 6878.0 6917.0 6839.0 N Bulk sediment # SUERC-21520 172.0 173.0 age14C 7039.0 7078.0 7000.0 N Bulk sediment # SUERC-17509 200.0 201.0 age14C 7304.0 7341.0 7267.0 N Bulk sediment # SUERC-21521 228.0 229.0 age14C 8661.0 8705.0 8617.0 N Bulk sediment # SUERC-21522 254.0 255.0 age14C 10212.0 10257.0 10167.0 N Bulk sediment # SUERC-17510 284.0 285.0 age14C 9738.0 9781.0 9695.0 N Bulk sediment # SUERC-21523 300.0 301.0 age14C 10213.0 10258.0 10168.0 N Bulk sediment # SUERC-21526 314.0 315.0 age14C 10610.0 10654.0 10566.0 N Bulk sediment # Poz-34966 63.0 64.0 age14C 5080.0 5120.0 5040.0 N Mixed terrestrial plant material # Poz-34208 99.0 100.0 age14C 3590.0 3630.0 3550.0 Y Betula bark # Poz-34967 179.0 180.0 age14C 5460.0 5500.0 5420.0 Y Mixed terrestrial plant material # Poz-34209 223.0 224.0 age14C 6250.0 6290.0 6210.0 Y Picea needles # Poz-34968 139.0 240.0 age14C 6780.0 6830.0 6730.0 Y Mixed terrestrial plant material # Poz-34210 289.0 290.0 age14C 9440.0 9490.0 9390.0 Y Wood # Poz-34969 297.0 298.0 age14C 9200.0 9250.0 9150.0 Y Mixed terrestrial plant material #------------------ # Variables # # Data variables follow that are preceded by "##" in columns one and two. # Variables list, one per line, shortname-tab-longname components (9 components: what, material, error, units, seasonality, archive, detail, method, C or N for Character or Numeric data) # ## depth depth,,,centimeter,,insect;paleolimnology;climate reconstructions,,,N,top 2 samples at 0.5 cm intervals ## age age,,,calendar year before present,,insect;paleolimnology;climate reconstructions,,,N,ages modelled from radiocarbon and Pb-210 data ## temperature surface air temperature,midge assemblage,,degree Celsius,Jul,insect;paleolimnology;climate reconstructions,,,N,Western Russian calibration dataset (Self et al. 2011);
