Species composition and abundance of soil algal flora
were studied in the Central zone of the Krasnodar region
on crops of crops cultivated by various technologies. In
the algal flora of the studied area, 48 species of soil algae
and cyanobacteria from 28 genera and 18 families, 7
classes and 4 divisions were identified. The largest and
numerous in number of species are the departments:
Cyanophyta and Chlorophyta. Extensive delivery:
Oscillatoria, Gloeocapsa. They account for 22 % of the
total number of species. A negative effect of herbicides on
number and species composition of soil algae was noted.
In all variants of their application there was no form of
Klebsormidium flaccidum (Kützing). The number of
species of Chlorella vulgaris Beyer. was low,
Botrydiopsis arhiza Borzi. It is believed that these species
of algae can be used as bioindicators. The positive effect
of mineral fertilizers and the aftereffect of introducing
organic matter on the soil algal flora have been
established. In these variants the deleterious effect of
herbicides was reduced. According to the calculated
regression equations, the applied mineral fertilizers to a
greater extent weakened the negative effect of herbicides
on the total number of populations than the aftereffect of
introduced organics
The article presents the results of studies on the species composition of fungi isolated from seedlings of grapes affected by vascular necrosis
The issues of international spread of fruits of long gourd lagenaria and the introduction of it in culture are considered in the article. We have shown how to use it as a vegetable crop and considered varietal diversity of this species. The biological characteristics of lagenaria cultivation as vegetable plants, including peculiarities of the reproductive system have been marked. We have also considered the issues of cultivation and
distribution of long gourd lagenaria (zycca) for food
Insects are a major component of natural biocenoses
and agrocenoses. One of the largest and most numerous
families are ground beetles (Carabidae); their
number, according to various estimates, is more than
30,000 species. For Carabidae beetles it is common to
have different ways of eating, a place of habitation,
occupied layers, seasonal and daily activity. They live
both on the surface and in the soil, more rarely on
bushes and trees. The types of the family of ground
beetles – active beetles with long, thin antennae of
uniform thickness, long elytra and long legs, adapted
to running. Their sizes vary from a few millimeters to
10 cm. As active predators, ground beetles play a huge
practical importance, destroying pests before reaching
the last threshold, thereby providing a natural regulation.
Based on the fact, that the number of beetles is
large, and their sizes are sometimes only a few millimeters,
there is a problem of determining the species
of these insects (or their identification), therefore it
took a special tool, which, on the one hand, facilitate
obtaining data about these insects, and on the other
hand, would increase their accuracy. This article proposes
a new (to this subject area) approach to identify
different species of ground beetles along their outer
contour with the use of software tools for automated
system-cognitive analysis (ASC-analysis) – the universal
cognitive analytical system called "Eidos,"
which is well-proven in the study of other objects. The
reason why it was decided to use this system is that
normal (standard) identification of ground beetles,
have certain disadvantages: the human factor (manifest
error in the determination); quite time consuming; the
inability to increase the number of criteria to improve
the reliability of the model comparison. This article
aims to overcome these drawbacks, by the use of universal
cognitive analytical system "Eidos", the automated
system-cognitive analysis (ASC-analysis). A numerical example is given
The article is devoted to the results of study of taxonomic situation and ecological features of venomous snake species spread in the territory of the Naxçıvan Autonomous republic. Materials for researches have been collected within 2011-2014 on different biotopes and landscapes according to altitudinal belts of the region. 4 venomous species like: Macrovipera lebetina, Montivipera raddei, Pelias renardi, Pelias dinniki and 2 semivenomous snake species like: Telescopus fallax and Malpolon monspessulanus were revealed in herpetofauna of the Autonomous Republic
The article presents the results of the research carried
out in 2007-2014. The aim of the study was the
composition of the microflora of the leaf surface of
some plants of the family Grossulariaceae. Based on
these data, the authors distinguish the typical
representatives of the leaf surface microflora. The
authors study the features of isolated strains
interactions
The article gives data on the importance of mikro-fundi in the Central part of the Caucasus, causing fungi of leaves and ear
The article deals with the specific features of the fantasy genre in J. Tolkien’s works. We also analyze the existing approaches to the problem in the context of West-European literary traditions and present a system of basic components of fantasy realized in Tolkien’s creative activity
Technological methods of rice cultivation in Rostov region are considered in the article. Broadcast sowing method with rolling down the soil, application of op-timum fertilizer doses before blossoming, water schedule for weed control are recommended. Low rice percentage crop rotation for farms with unsatisfactory financial position and minimum technical equipment are suggested
The article is devoted to the problem of practical application of the modern linguistic theory: frame semantics. The meanings of the verbs as the parts of language are investigated through their cognitive representation. The article deals with the problem of formation, description and representation of the frame components on the language level
