Phenological Response of Plants of Different Biomorphs to Climate Change in Western Siberia

The results of a phenological study of 78 species of perennial plants from biomorphological groups of chamaephytes, hemicryptophytes, and geophytes over a 20-year period (1996-2015) are discussed. Against the background of air temperature and precipitation changes of the warm season in Novosibirsk, the timing shift in phenological events have been analyzed using calculated linear trends. It is found that the trends for species groups are multidirectional and vary significantly in magnitude. At the same time, most of the shifts in phenology are due, not to trends, but to the interannual variability of climatic indicators.
