The article presents the results of studying the fruiting in 9 clematis cultivars under the conditions of the southern coast of Crimea. Morphometric characteristics of seeds, their weight and germination capacity are given. Potential and real seed production was assessed. It was found that the studied cultivars are characterized with high potential seed production, on average from 38.1 to 116.9 ovules per fruit, but relatively low real seed production, on average from 1.3 to 8.3 seeds per fruit.

The vitality structure of cenopulations of woody plants is formed under the influence of ecological, cenotic and anthropogenic influences. The study of the nature and degree of influence of the ecological parameters of the habitat will make it possible to predict the formation of the vitality structure of woody plants. The objects of study are individuals of the generative age state of three species of woody plants: Quercus robur, Tilia cordata, Acer platanoides. Environmental conditions of habitat were assessed by using range ecological scales.

The progressive growth of bacterial resistance to antibiotic drugs requires the creation of highly efficient nanomaterials. Aluminum oxide is a stable non-toxic semiconductor material; however, the photocatalytic properties of its modifications in relation to microorganisms are not well understood. In this study, we used new 3D composites of aluminum oxyhydroxide (Al2O3 ? nH2O) in three modifications (?, ? and ?), which are a mesh of 150 nm nanofibrils.

 Records of 94 vascular plant species from the Penza Region published before 2013 are missing from the 11th edition of the «Flora of the Central Part of European Russia» by P. F. Mayevsky (2014). An additional 22 species were discovered in the region recently. At least 29 species known in the Penza Region are completely missing from the «Flora…» – Stellaria subulata Boeber ex D. F. K.

In today’s modern technogenic world, forming an ecological consciousness, perception and thinking among schoolchildren is a vital task. Knowledge of chemical toxicology is essential for students of all ages to help protect and maintain a healthy environment. Given that toxicology is characterized by an increased level of complexity, the purpose of this work was to develop and apply gaming methods in teaching the basics of chemical toxicology as part of environmental education of schoolchildren.

Significant researches aimed at the greening of agro-industrial production are focused on obtaining immobilized bacterial preparations with preserved proliferative function and metabolic activity. Herein, we investigated the possibility of bacteria of the genus Azospirillum to be immobilized in Ca-alginate beads. A. brasilense SR80 cells, encapsulated in an alginate hydrogel, were obtained using the “soft” immobilization method based on physical binding.

Currently, new habitats of scorpions of the genus Mesobuthus have been established on the territory of the republics of Armenia and Dagestan. The aim of the study was to determine the phylogenetic position of scorpions inhabiting the territories of the Republic of Armenia and the Republic of Dagestan. This study contributes to the development of ideas about the zoogeographic distribution of the scorpion fauna in the Palaearctic.

The Herbaspirillum lusitanum P6-12 strain containing the vector plasmid pJN105TurboGFP, which encodes the synthesis of the green fluorescent protein GFP, and which has resistance to the antibiotic gentamicin, was obtained by electroporation. The constructed strain of H. lusitanum P6-12 in cultural, morphological and biochemical properties did not differ from the original typical natural strain of H. lusitanum P6-12. On solid growth media, the recombinant strain formed yellow-green colonies, fluorescent under UV irradiation.

This article describes the characteristics of the beetle fauna – inhabitants of fruiting bodies and the mycelial layer of the true tinder fungus Fomes fomentarius L.: Fr. and are considers some important aspects of the ecology of mycetophilous beetles. Coleopteran population of fruiting bodies of the fungus in five districts of the Saratov region is 63%. Two species from the family Staphylinidae (Gyrophaena joyi Wendeler, 1924 and Scaphisoma boreale Lundblad, 1952) have been recorded on growing and / or spore bearing fruiting bodies.

An extracellular polymer was isolated from the culture liquid of Bacillus subtilis EGP5QL12 with the yield of 5,6 g/L. On the basis of the data of thin layer chromatography, colorimetric analyses and FTIR spectroscopy, it was established that the polymer is poly-?glutamic acid (PGA). PGA is widely used in medicine, cosmetology and the food industry due to its ability to bind water and metal ions.
