| description | For nominally indigenous forests of the Trans-Urals hilly piedmont province of the Middle Urals, the species composition and productivity of the lower layers – as an adaptation to different humidity regimes – were studied. The research is based on three forest types (by the principles of genetic typology): cowberry pine forest, grass pine forest, and dwarf shrub-sphagnum pine forest. The investigated plots constitute a generalized topoecological profile. In the lower layers of the studied pine forests, the species composition differs considerably. The species richness differs significantly between the extreme (periodically dry and permanently humid) and optimal (fresh, periodically humid) habitats. The humidity factor is important. The productivity of the lower layers is stable regardless of the humidification conditions. This indicates that ecosystems have a higher adaptive capacity than individual plant species. To study the mechanisms by which the productivity is maintained, we constructed the rank distributions of the above-ground phytomass of grass species in the all three types of pine forests. We found that a statistically significant increase takes place in the β parameter of the exponential approximating function when the soil humidity decreases as the productivity level of the grass-dwarf shrub layer is maintained. |
