Halophytic vegetation and adjoining plant communities in Middle Asia (Pamir-Alai and western Tian Shan)
2021
In this paper, we complete the syntaxonomical scheme for halophytic vegetation and adjoining plant communities of the lowland, montane and alpine zones in the Pamir-Alai and western Tian Shan in Tajikistan and Kyrgyzstan with some remarks on its environmental predictors. A total of 217 relevés were sampled in 2014–2019 using the seven-degree cover-abundance scale of the Braun-Blanquet approach. Modified TWlNSPAN was used to classify plant communities based on species composition. The cover-abundance scale was transformed using the four-step interval scale with cut-off levels at 0%, 5% and 25%. Diagnostic species were identified using the phi coefficient as a fidelity measure. Non-metric Mul…
Resistance of solonetzic soils to rocket and space activity impact in central Kazakhstan.
2018
Introduction. This paper provides the results of a comparative analysis of physicochemical and biological characteristics of soil cover at the fall places of the first stage of “Proton" Launch vehicle (LV) in the area of Yu-2 (Central Kazakhstan). In particular, we considered the ecological stability of brown solonetzic soils in combination with Solonetz soil, to chemical pollution and variability of soil microflora to mechanical stresses during the fall of the separated parts of space launch vehicles (SLV SP). Materials and Methods. We have chosen those Kazakhstan's territories that are used by the Baikonur Cosmodrome as an impact areas of separating parts of space launch vehicles (SLV SP …
