Holocene treeline dynamics in the mountains of northeastern British Columbia, Canada, inferred from fossil pollen and stomata
Changes in pollen and stomata assemblages in sediment cores recovered from tundra and foresttundra lakes in alpine regions of northeastern British Columbia reflect vegetation and inferred climatic change throughout the Holocene. Pollen and stomata records are presented from two lakes, BC2 located in the alpinetundra zone and Dead Spruce Lake at the present elevation of subalpine treeline. The pollen and stomata records from BC2 indicate that an e…
Diatom, Pollen, and Chemical Evidence of Postglacial Climatic Change at Big Lake, South-Central British Columbia, Canada
Postglacial climatic conditions were inferred from cores taken from Big Lake in southern British Columbia. Low concentrations of nonarboreal pollen and pigments near the base of the core suggest that initial conditions were cool. Increases in both aquatic and terrestrial production suggest warmer and moister conditions until ∼8500 cal yr B.P. Hyposaline diatom assemblages, increases in nonarboreal pollen, and increased concentrations of pigments …
Holocene Treeline History and Climate Change Across Northern Eurasia
Radiocarbon-dated macrofossils are used to document Holocene treeline history across northern Russia (including Siberia). Boreal forest development in this region commenced by 10,000 yr B.P. Over most of Russia, forest advanced to or near the current arctic coastline between 9000 and 7000 yr B.P. and retreated to its present position by between 4000 and 3000 yr B.P. Forest establishment and retreat was roughly synchronous across most of northern …
Response of the Central Canadian Treeline to Recent Climatic Changes
Dendrochronology and the analysis of historical records from eighteenth, nineteenth, and early twentieth-century expeditions are used to reconstruct the response of the central Canadian treeline to recent climatic variations. Cold summer temperatures during the early to mid-nineteenth century contributed to low rates of growth and poor recruitment of white and black spruce at treeline. Despite the harsh conditions, however, individuals of both sp…
A 930-year ring-width chronology from moisture-sensitive white spruce (Picea glauca Moench) in northwestern Canada
A 930-year tree-ring chronology was constructed from living and subfossil white spruce ( Picea glauca Moench) from the Campbell Dolomite Upland, Northwest Territories, Canada. Response function analy sis using climate data from nearby Inuvik indicates that 69% of the variation in ring widths can be explained by monthly precipitation and temperature. Ring width is most strongly correlated with high precipitation between February and May. There is …
Dendroclimatic Reconstruction of Summer Temperatures in Northwestern Canada since A.D. 1638 Based on Age-Dependent Modeling
Ring widths from five Picea glauca stands at the alpine treeline in northwestern Canada are used to investigate climate-growth responses and to develop a long reconstruction of summer temperatures. Response function and linear regression analyses indicate that the radial growth response of these trees to climate varies with age and site. At most sites, the period of significant positive response to growing season temperatures declines with tree a…
