Dendroclimatological Investigations of Sea Buckthorn (Hippophae rhamnoides) and Reconstruction of the Equilibrium Line Altitude of the July First Glacier in the Western Qilian Mountains, Northwestern China

“…This result was similar to those of previous studies, in which the temperature of the growing season played an important role in treering growth near the cold high-elevation treeline (Jacoby et al 1985;Zhang and Hebda 2004). However, our results differed from previous studies that showed annual radial increment being further controlled by precipitation and temperature prior to the growing season near the treeline in the central Tianshan Mountains (Wang et al 2005), and that showed spring precipitation as a significant factor for tree growth at high-elevation sites in the central Qilian Mountains (Gou et al 2005).…”

The Potential to Reconstruct Manasi River Streamflow in the Northern Tien Shan Mountains (NW China)

“…Previous studies have shown that Tien Shan spruce is a valuable species for tree-ring analysis (Wang et al , 2005Li et al 2006). Precipitation is the principal limiting factor for Tien Shan spruce growth in the Tien Shan Mountains, even at high-elevation tree-line sites (Wang et al 2005).…”

“…Tree-ring analysis has been successfully applied to reconstruct drought variability in central Asia (Pederson et al 2001;Wang et al 2005;Davi et al 2006;Li et al 2006;Treydte et al 2006). Tree-ring based streamflow reconstructions have been developed for many areas (e.g.…”

Growth-form regulates the altitudinal variation of interspecific seed mass of woody plants in Mt. Dalaoling, the Three Gorges Region, China
