Variation of the hydrological regime of Bele-Shira closed basin in Southern Siberia and its reflection in the radial growth of Larix sibirica

Regional Environmental Change - This study analyses dynamics of the hydrological regime of Bele-Shira closed basin and evaluates the potential for using radial growth of Siberian larch (Larix...     

Earlywood and Latewood Features of <Emphasis Type="Italic">Pinus sylvestris</Emphasis> in Semiarid Natural Zones of South Siberia

Chronologies of the anatomical and integral parameters of the Scots pine (Pinus sylvestris L.) earlywood and latewood were investigated for two sites in the Minusinsk depression with different soil moisture conditions. Patterns of statistical characteristics and climatic responses of the chronologies were identified. Differences between sites were revealed in the cell diameter and wall thickness distributions. These differences are indicators of adapting pine wood structure to the moisture deficit.     

Climatic signal in radial increment of conifers in forest-steppe of southern Siberia and its dependence on local growing conditions

Radial increments have been studied in Siberian larch (Larix sibirica Ledeb.) and Scots pine (Pinus sylvestris L.) growing in the forest-steppe zone of southern Siberia in areas with different landscapes and levels of soil moisture supply but uniform climatic conditions. It has been shown that the radial increment significantly depends on climatic factors, primarily temperatures in April to July and September, sums of precipitation in April to July and September to November, and hydrothermal coefficient in May. The climatiC response in the wood of conifers in the forest-steppe zone differs depending on their species-specific features and local growing conditions.
