Dynamics of species composition in the herbaceous-subshrub later of pedunculate oak (Quercus robur L.) plantations following canopy closure in a moist, relatively fertile site type in Zhytomyr Polissia

Біологічні студії
Background. In recent decades, the area of mature oak forests in Ukraine has been declining due to clear felling. Additionally, the existing network of protected areas is insufficient to encompass the full diversity of natural oak forests.

Sedum plant communities, applying on green roofs and dynamic of development

RUDN Journal of Agronomy and Animal Industries, 2012
The analysis of plant communities on green roofs of different ages, created by the same technology and using the same set of species, reveals the dynamics of change in species composition and area of the projective cover of plants in the absence of ...

Regeneration of Rhododendron luteum Sweet (Ericaceae) undergrowth after main clear cuttings in Ukrainian Polissia

Біологічні студії
Background. The yellow azalea (Rhododendron luteum Sweet) is a relict species, fragmentally distributed in Ukraine, particularly in the Zhytomyr Polissia, covering an area of approximately 62.000 ha.

A tower of coverings of quasi-projective varieties

Advances in Mathematics, 2012
The main goal of this article is to relate asymptotic geometric properties on a tower of coverings of a non-compact K hler manifold of finite volume with reasonable geometric assumptions to its universal covering. Applicable examples include moduli spaces of hyperbolic punctured Riemann surfaces and Hermitian locally symmetric spaces of finite volume.

The KSBA moduli space of stable log Calabi–Yau surfaces

Forum of Mathematics, Pi
We prove that every irreducible component of the coarse Kollár-Shepherd-Barron and Alexeev (KSBA) moduli space of stable log Calabi–Yau surfaces admits a finite cover by a projective toric variety. This verifies a conjecture of Hacking–Keel–Yu. The proof
