Other claims from this paper (13)
- Observation Betula humilis dominates the shrub layer (40-80% p.c.) in the least transformed communities.
- Observation Seventy-five species of higher plants were found in the floristic composition of the phytocenoses.
- Observation The minimal participation of helophytes and the presence of invasive species indicate a high level of mesophytization and synanthropization of the modern phytocenoses.
- Observation The largest curtains of Betula humilis (up to 300 m2) are confined to open well-lit areas.
- Observation Living formation shoots of Betula humilis reach a high density (up to 293 pcs/m2) in the largest curtains.
- Observation The age of the old skeletal axis of Betula humilis did not exceed 9 years.
- Observation The annual growth of Betula humilis shoots was calculated.
- Observation Potential seed productivity of the local Betula humilis population ranges from 89.48 to 109.24 seed germs.
- Observation Actual seed productivity of the local Betula humilis population ranges from 80.84 to 100.4 seeds.
- Observation The coefficient of seed productivity of Betula humilis is 86.69-92.16% for all coenopopulations.
- Observation Betula humilis belongs to vegetatively mobile hypogeogenic-geoxyl deciduous shrubs by life form.
- Observation The development cycle of the system formation shoot covers intensive growth in the first year and ageing and death of shoots after about ten years of age.
- Observation The big life cycle of Betula humilis lasts for decades.
