Since density is considered as one of the most important numerical indices to explain quantitative values of a plant community by affecting on many aspects and activity of ecosystem, on the other hand, awareness about plants distribution pattern in environment is an essential preparation for measurement and study of vegetative cover, therefore, in this research determination of density and dist...

Curculionoidea (hereinafter – weevils) comprises the largest group of phytophagous beetles. They are an integral component terrestrial and freshwater communities associated with a wide range plants. Therefore, weevils can serve as one model taxa for assessing diversity specificity biota, including those in Protected Areas various ranks. This article is based on results original studies (in 2011...

We studied the history of F.E. Falz-Fein Biosphere Reserve “Askania-Nova”, which can be divided into several periods. The first period is founding Askania-Nova estate by German Duke F. Anhalt-Kothen (1841). second associated with activities: organization a zoo semi-free animals (1874), establishment dendrological park artificial irrigation (1887), bequest virgin steppe territories (1898). next ...

Flora and vegetation data of the nature monument regional importance “Elandinsky stones” (Tselinnyy district, Altai Krai) are given. comprises 283 species higher vascular plants, including 2 rare species: Paeonia hybrida, Stipa pennata. Vegetation is represented by petrophyte forb-feathergrass steppe, for Bijsk-Chumysh upland, forb-grasses meadow, birch forests bushes.

Sagebrush (Artemisia spp.) steppe is one of North America's most imperiled ecosystems, as the result of many factors including grazing, development, fire, and invasion of exotic plants. Threats to sagebrush steppe are expected to increase because of climate change and further human development. Many songbirds use sagebrush steppe opportunistically, but a few obligate species are dependent on it...

Purpose. To evaluate the quality indicators of spring barley seeds grown under different soil and climatic conditions. Methods. Laboratory, calculation statistical methods were used during research, analysis synthesis to draw conclusions. Results. As a result dependence indicators, namely: grain uniformity protein content, on zones growing conditions was revealed. Thus, ranged from 86.7% (high,...

Purpose. To estimate the ecological plasticity of common millet yield under conditions Steppe, Forest-Steppe and Forest Ukraine. Methods. Mathematical statistical: determination stability by Eberhart & Russell method, correlation analysis. Results. As a result analysis cultivated areas during period 2011–2020, it was revealed that in Ukraine depend on world ones (r = 0.34). It determined hi...

The relationship between species richness (SR) and aboveground net primary productivity (ANPP) is still a central and debated issue in community ecology. Previous studies have often emphasized the relationship of alpha diversity (number of species identity) to the mean ANPP with respect to the SR-ANPP relationship while neglecting the contribution of beta diversity (dissimilarity in species com...

Sediment cores from Carp Lake provide a pollen record of the last ca. 125,000 years that helps disclose vegetational and climatic conditions from the present day to the previous interglaciation (120–133 ka). The core also contained 15 tephra layers, which were characterised by electron-microprobe analysis of volcanic glass shards. Identified tephra include Mount St. Helens Ye, 3.69 ka; Mazama a...
