Wood samples of pine were collected from 8 sites(Fig.1a;Table 1)in the forest-steppe zone of basin,where trees are expected to be moisture-sensitive.The forest-steppe is characterized by low-productive open pine dry stands on sandy soils.The sparse underbrush is represented by Dasiphora fruticosa L.,Rosa acicularis Lindl.,Spiraea trilobata L.,and Cotoneaster melanocarpus Fisch.ex Blytt.The grass has a total coverage of 5%–15%and predominantly consists of steppe species,i.e.,Stipa krylovii Roshev.,Koeleria macrantha(Ledeb.)Schult.,Scabiosa comosa Fisch.ex Roem.&Schult.,and Thymus serpyllum L.The first sample collection was carried out in 1999 by Andreev et al.(1999).To prolong series,we performed an additional sample collection in 2015,but not at all sampling sites(Demina et al.,2017).Both times,not suppressed healthy living trees were selected,and cores were sampled with the 5-mm-diameter increment borers at breast height(~1.3 m).
