Arctic ecosystems have been afflicted by vast changes in recent decades. Changes in temperature, as well as precipitation, are having an impact on snow cover, vegetation productivity and coverage, vegetation seasonality, surface albedo, and permafrost dynamics. The coupled climate-vegetation change in the arctic is thought to be a positive feedback in the Earth system, which can potentially further accelerate global warming. This study focuses on the co-occurrence of temperature, precipitation, snow cover, and vegetation greenness trends between 1981 and 2012 in the pan-arctic region based on coarse resolution climate and remote sensing data, as well as ground stations. Precipitation significantly increased during summer and fall. Temperature had the strongest increase during the winter months (twice than during the summer months). The snow water equivalent had the highest trends during the transition seasons of the year. Vegetation greenness trends are characterized by a constant increase during the vegetation-growing period. High spatial resolution remote sensing data were utilized to map structural vegetation changes between 1973 and 2012 for a selected test region in Northern Siberia. An intensification of woody vegetation cover at the taiga-tundra transition area was found. The observed co-occurrence of climatic and ecosystem changes is an example of the multi-scale feedbacks in the arctic ecosystems.

“…The climatic parameters from any such single station cannot be assumed to be representative of regional climate and may not provide ideal data for calibrating treering data from distant sites (Mitchell et al, 1996). In such cases averaging of two or more meteorological station records avoids many problems associated with record inhomogeneities and deferring station microclimates so that they can provide potentially more reliable data to calibrate tree-ring chronologies (Blasing et al, 1981;D'Arrigo and Jacoby, 1993;Jacoby et al, 2000). In addition, Fritts (1976) and Pant and Borgaonkar (1984) suggested the use of climatic data of stations located even at some distances from the tree-ring sites for the calibration of tree-growth climate relationships.…”

Climatic signal in tree-ring chronologies of Cedrus deodara from Chitral Hindukush Range of Pakistan

Tree-rings are an important tool for the investigation of paleoclimatic records for regions or periods of time with no instrumental climatic data. However, the responses of different species and sites to various climatic parameters are unusual. In the present study, we developed tree-ring-width chronologies of Cedrus deodara from three different sites of Chitral Hindukush range of Pakistan. The study was conducted to understand tree-growth climate relationship and its applicability in proxy climate investigations. The chronologies covered the past 469 to 595 years, with a mean segment length (MSL) ranging from 148 to 223 years. Climatic data obtained from the three weather stations showed strong correlation and was found useful for tree-ring climate relationships. Correlation Function (CF) and Response Function (RF) analysis showed that spring precipitation (March-May) is a critical limiting factor for tree-ring growth, and temperature prior to November may also play a major role in affecting tree ring-growth. The results exposed that the three sites have continuous relationship indicated that only single species from different locations are affected by the same environmental variables and hence can be used in climate reconstruction in combination. The Cedrus deodara chronologies developed at different locations had several corresponding narrow and wide marker rings indicating a large macroclimatic response to regional climatic conditions. The current study suggests that the tree-rings of Cedrus deodara from the Chitral Hindukush range could be used to develop chronologies for the reconstruction of seasonal climatic variables.

“…In the Eurasian continent, larch forests are also experiencing changes in growth patterns possibly caused by warming and associated changes. For example, Vaganov et al (1999) and Jacoby et al (2000) report loss of thermal sensitivity in tree growth that may be related, in part to changes in seasonality.…”

“…Recent productivity studies suggest that larch forests currently function as net carbon sinks, but caution that warming trends may increase tree vulnerability to drought stress, fire, and insect infestation, and result in an increased carbon source (Kobak et al 1996;Gower et al 2001). Furthermore, dendroclimatic studies at treeline in Siberia suggest a change in the response of larch growth to warming temperatures; the sense of this change is that there is less vigorous growth than expected with the warming (Briffa et al 1998;Vaganov et al 1999;Jacoby et al 2000).…”

Climate Response of Dahurian Larch in Secrest Arboretum, Wooster, Ohio, USA

Larix gmelinii (Rupr.) Kuzen. (Dahurian larch) is an important arctic tree-line species in the northern boreal forests of Eurasia. The region's climate is predicted to change dramatically over the next century, yet little is known about how this species will respond to secular changes in temperature and precipitation. To this end, a ring-width chronology from 25 cores from a stand of seven Dahurian larch trees growing in the Secrest Arboretum, northeastern Ohio, was developed to test the climatic sensitivity of the species in a more temperate climate. The chronology extends from 1931 to 2005 and correlation analysis with monthly precipitation and temperature records shows growth was most strongly limited by summer precipitation until recent decades when sensitivity has shifted to late spring precipitation. The results from this study serve as a contemporary analog to the future growth response of Dahurian larch under warmer and wetter growing conditions in the boreal and arctic regions of Eurasia.
