Assessment of effect of different types of degradation processes on species richness, floristic composition and diversity of ecosystems of subalpine and forest zones was conducted. It was established that altitude gradient as well as types of degradation processes have strong impact on these characteristics. The results confirmed disturbances hypothesis concerning biodiversity changes in ecosy ...

Responses of soil respiration to altered precipitation are analyzed for 4 types of experiment and the control plots at the experimental site of Karadag Nature Reserve. The diurnal dynamics of the soil respiration on the control plots in June 2012 is characterized; the monthly dynamics of the soil respiration for March 2012 – July 2013 is shown; the linear multifactor regression analysis is don ...

The article presents the results of testing of the improved methodology of assessing losses caused by the damages of natural biotopes and their components. The basic parameters of the proposed methodology are biomass and productivity of ecosystem components, expressed in energy terms, taking into account the recovery time of ecosystems. These parameters balance the assessment of loss of stable ...

Biotops of central Podillya

Ya. Didukh et al. [2013]

Biotops of Central Podillia and their differentiation measures were firstly identified and characterized in the article. On the basis of synfytoindication methods limiting ranges of leading ecological factors and their correlation were determined. These results are very important for the nature conservation.

The frequencies of unbalanced gametes were analyzed by fluorescence in situ hybridization on decondensed interphase sperm nuclei of reciprocal and Robertsonian translocation carriers with the combination of probes that allowed identification of all variants of chromosome segregation. A homogenous segregation pattern with the predominance of normal/balanced sperm formation was observed in Rober ...

It was studied the literature data of the ability of bacteria of the genus Bacillus to form red and yellow colors’ pigments, analyzed their structure and biochemical routes of synthesis. It was investigated that the vast majority of pigments produced by Bacillus spp. relates to compounds of carotenoids nature. Also was evaluated the probiotic abilities of Bacillus strains and proposed the oppo ...

Palynological materials of the Late Holocene deposits of Ukrainian Polissya were analysed and summarized. The total list of the anthropogenic component in the palynoflora from the deposits and archaeological sites was identified (41 taxa total). The list of model synanthropic taxa is developed for paleomorphological and paleochorological studies. The maps of their distribution on the territory ...
