Climate changes and overstory recruitment of larch at the northern timberline in the Yamal Peninsula
Studies on overstory recruitment of the Siberian larch (Larix sibirica Ledeb.) in open larch forests depending on the time of seedling establishment (1880–1980) have been performed in the northern timberline ecotone on the Yamal Peninsula. Two periods of active larch establishment have been revealed: from 1900 to 1935 and from 1950 to 1970. A comparison of these data with the results of instrumental observations on temperature and precipitation has shown that the overstory recruitment of larch in valleys of northern rivers is largely dependent on July air temperatures in the first years of tree life, when seedlings grow 10–20 cm high. 相似文献

The results of identification and dating of frost, false, and light rings in the wood of living and dead Siberian juniper
plants growing at the upper forest boundary in the Polar Urals were used to determine the incidence of these structures over
the past 630 years. Based on the data of instrumental observations on daily air temperature, the dates and rates of temperature
decrease in the years of pathological tree ring formation were analyzed. The recurrence and intensity of extreme temperature
drops during the growing seasons of the past six centuries were reconstructed. The severest frosts occurred in the summer
seasons of 1601, 1783, 1857, 1882, and 1968. 相似文献
