The line that marks the boundary between the boreal forest and the tundra regions is a relatively abrupt line in central Canada and appears to reflect a clearly defined climate boundary. Research suggests that relatively small changes in the climatic conditions should result in a movement of the treeline. Such a movement was apparently reported in 1772 by Samuel Hearne based upon the observations of generations of Indians who had lived in the area. A map of his voyages indicates a tree limit… Expand
The arctic tree line as a record of past and recent climatic changes
Past and recent changes in the position of the arctic tree line and spatial structure of nearby forests are reviewed and major displacements deduced from dendroecological data were recorded during the last 500 years. Expand
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 toExpand
Neoglacial Climate Control of Subarctic Picea abies Stand Dynamics and Range Limit in Northern Sweden
The study focused on the performance of the spruce (Picea abies [L.] Karst.) range limit in northern (subarctic) Sweden during the Neoglacial period of the Holocene, mainly after the climax of theExpand
SUMMARY The natural decline of a virgin high-altitude Pinus sylvestris forest during the Little Ice Age (approximately AD 1300–1850) was studied in the Swedish Scandes. Methods included 14C andExpand
Monitoring Forest–Tundra Ecotones at Multiple Scales
The transition from forest to tundra in Arctic and alpine regions, frequently referred to as treeline, has preoccupied biogeographers and ecologists for more than a century. It is widely hypothesizedExpand
Holocene evolution of lakes in the forest-tundra biome of northern Manitoba, Canada
Abstract The late-Quaternary paleoenvironmental history of the western Hudson Bay region of Subarctic Canada is poorly constrained. Here, we present a regional overview of the post-glacial history ofExpand
A high late Holocene tree-limit and the establishment of the spruce forest-limit - a case study in northern Sweden.
Radiocarbon dates of subfossil pines found on dry ground above the present-day tree-limit are reported from northern Sweden. The uppermost and oldest specimen germinated c. AD 300–600. During someExpand
Polar bears of western Hudson Bay and climate change: Are warming spring air temperatures the “ultimate” survival control factor?
Abstract Long-term warming of late spring (April–June) air temperatures has been proposed by Stirling et al. [Stirling, I., Lunn, N.J., Iacozza, J., 1999. Long-term trends in the population ecologyExpand
Impacts of Hudson Bay on the Terrestrial Climate of the Hudson Bay Lowlands
Hudson Bay remains frozen or is dominated by ice over the summer solstice and throughout much of the high-sun season. This contributes directly to the winterization of summer. The juxtaposition ofExpand
Age distribution patterns in open boreal Dahurican larch forests of Central Siberia.
A high correlation was found between the Weibull function coefficients and the coefficient of age variation and for the mean age and in the oldest stands the distribution had a platykurtic form. Expand


The Stability of the Northern Canadian Tree Limit
ABSTRACT This paper presents data on and discusses the degree of postglacial stability of the northern Canadian tree limit. Holocene climatic changes have been both directional and synchronous forExpand
Secular climate change in old-growth tree-line vegetation of northern Quebec
The climate of the Northern Hemisphere changed during recent centuries, as shown by the Little Ice Age episode1 and the warming trend of the past 100 years2,3. The ecological impacts of these changesExpand
Multivariate statistical estimates of Holocene vegetation and climate change, forest-tundra transition zone, NWT, Canada
Abstract Newly derived fossil pollen data were obtained from four sites along a transect from the boreal forest limit into tundra in the eastern Northwest Territories. Multivariate statisticalExpand
Holocene Climatic Changes in Relation to Vegetation Disjunction and Speciation
A review of plant distributions in central California indicates that important shifts in the area occupied by vegetation, as well as species, may result from a change of only 1⚬ C in mean temperatureExpand
Historical Aspects of the Northern Canadian Treeline
From palynological studies it appears that northernmost dwarf spruces of the tundra and parts of the forest-tundra boundary may be relicts from times of prior warmth, and if felled might notExpand
The Post-glacial history of vegetation and climate at Ennadai Lake, Keewatin, and Lynn Lake, Manitoba (Canada)
Abstract. Peat from Keewatin and Manitoba contained macrofossil and palynological evidence of former latitudinal movements of the forest — tundra boundary probably in response to the changingExpand
Late-quaternary vegetation and climate near the arctic tree line of northwestern North America
Earlier studies in Alaska and northwest Canada have shown inconsistent evidence for the expected northward extension of the Arctic tree line during the Hypsithermal Interval. Only megafossil evidenceExpand
Palaeoclimatological aspects of the synoptic climatology of Keewatin, Northwest territories, Canada
Abstract Mean monthly composite patterns of surface weather anomalies and 700 mbar height anomalies are determined for snowy winters and cool summers in both Keewatin and Labrador-Ungava and also forExpand
Climatic change in central Canada : a preliminary analysis of weather information from the Hudson's Bay Company Forts at York Factory and Churchill Factory, 1714-1850.
A reconstruction of climate at the southern end of Hudson Bay has been developed for the period from 1714 to 1852 from diaries, weather journals and instrumental records maintained by employees ofExpand
Re‐evaluation of Pollen‐Climate Transfer Functions in Keewatin, Northern Canada
ABSTRACT Multivariate statistical analyses allow specification of pollen-climate transfer functions useful in studies of paleoclimate. Two previously published models, when applied to two documentedExpand
