Weather conditions favouring cone initiation for Siberian stone pine (Pinus sibirica Du Tour)

FORESTRY BULLETIN, 2023
Seed production in 25 trees of Siberian stone pine (age 180-200 years) over a 28-year period was examined to determine how the weather factors and their period influence strobilus initiation. Since floral induction in Siberian stone pine occurs in a short period of time only during three weeks at the end of summer, the dynamics of temperature and ...

Not herbs and forbs alone: pollen‐based evidence for the presence of boreal trees and shrubs in Cis‐Baikal (Eastern Siberia) derived from the Last Glacial Maximum sediment of Lake Ochaul

Journal of Quaternary Science, Volume 37, Issue 5, Page 868-883, July 2022., 2022
ABSTRACT A new accerator mass spectrometry (AMS)‐dated sedimentary record from Lake Ochaul (54°14′N, 106°28′E; 641 m a.s.l.) in Eastern Siberia covers the interval from ca. 27 850 to 20 400 cal a bp at ca. 180‐year resolution and contributes to a better understanding of the complex spatial vegetation pattern during the Last Glacial Maximum (LGM).
