Abstract:

The hyerarchy of living systems comprises three categories of systems with distinct structures and functions: the individual, the multiindividual and the multicoenotic ones. Individual systems are: the prokaryotic unicellular organism, the eukaryotic unicelllar system and the pluricellular one. Multiindividual systems are the species and the biocenosis. Species, being differentiated regarding their ecological adapations, can exist only associated in biocenoses (through their populations), never independently; this is why the biocenosis is the only natural multiindividual, ecological system, consisting of other multiindividual systems – species. Multicenotic systems are: the biolandscape, the bioregion, the biozone (biome) and the biosphere. These systems comprise ensembles of different types of biocenoses and look like living covers of various sizes.

Abstract:

Spatial distribution, species structure and ecological indicators of macrozoobenthos of flowing water bodies by altitude belts of Nakhchivan Autonomous Republic were studied. Macrobenthos fauna of the rivers of the region is formed in psammoreophilic, phytoreophilic and peloreophilic biocenoses with a great advantage of lithoreophilic biocenosis. The lithoreophilic biocenosis of rivers of the mountain and high-mountain belts is characterized by extensive area and abundance of species diversity. The core of the lithoreophilic biocenosis is composed of populations of rheophilic organisms such as moths, mayflies, vernal pools and simulids; its usual inhabitants are also rheophilic larvae of chironomids of the genus Polypedilum, Endochironomus, Eukiefferiella, Cricotopus and Orthocladius. The family composition of the fauna was found to be relatively stable along the rivers. Differences in the species composition of macrobenthos fauna, change of dominant species in biocenoses are related to biological features of the main species, anthropic and anthropogenic impacts, as well as different time of research. The species composition of macrozoobenthos of the rivers of the autonomous republic decreases from the source to the mouth.

Abstract:

The results of research conducted in the period 2002–2004 and 2019–2022 on the study of the ecology of gamasid mites living on biocenoses of cotton, wheat and melons in the northern regions of Turkmenistan are presented. In particular, 10 species of gamasid mites were identified in the listed biocenoses, including 3 new species for the fauna of the country. According to the selectivity of ecological niches, the discovered mites are classified as eurybionts and geophyllobionts. The importance of predatory gamasid mites in biocenoses is shown in regulating the number of herbivorous mites. Some insects and nematodes, the role of gamasid mites as the main component in the biocenosis, which ensures the functioning of the predator-prey relationship, is proved. Laboratory observations revealed the specificity of the choice of prey by predatory mites in the species B. tarsalis, Ph. plumifer and N. bicaudus. The specifics of the choice of prey by the tick Ph. plumifer in the laboratory in the optimum temperature range of +20 – +25°C and a humidity degree of 40-65%. They actively bred on tea rose leaves when C. pulcher was used as a mite victim. The results of observations under a stereomicroscope on the study of the ethological characteristics of the predatory mite N. bicaudus during its attack on its prey in the leaves of an apple tree are also presented. Researches have revealed the specificity of the choice of the herbivorous mite Siteroptes tameri by the predatory mite N. bicaudus as a prey. The active role of the latter in the spread of spores of the fungus N. gossypii has also been proven. Field observations revealed that predatory mites G. aculeifer, B. tarsalis and N. bicaudus feed on herbivorous mites in biocenoses. For predators, specific types of prey have been established, related to spider mites, acaroid and eriophyid mites. The role of gamasid mites in establishing the ecological balance of herbivorous mites in biocenoses has been proved.

Abstract:

In this research, the species composition and structure of macrophytobenthos, macrozoobenthos, and bottom sediments of the Taman Bay, one of the areas of the Sea of Azov where the seagrass Zostera marina L. forms underwater meadows. The material was collected in 2008–2009 before of the Sea of Azov salinization. Three main zones with different types of bottom sediments (sands, sands with shells and silts) were identified, within which four main macrobenthic biocenoses were located (unvegetated coastal biocenosis, mosaic macrophyte communities outside the surf zone, Z. marina underwater meadows and the central regions’ biocenosis with the dominance of mobile forms of macrozoobenthos and a low abundance of macrophytes). The main environmental factor associated with this distribution of macrophytobenthos was the content of silt (with a granule size of less than 0.001 mm). The spatial structure of the macrozoobenthos correlated with the projective cover of Z. marina. Possible reasons for the revealed regularities in the distribution of communities are discussed.

Abstract:

Sequencing batch reactors (SBR) are often used for research on nutrient removal systems. A model anaerobic-oxic SBR was compared with a compartmentalized continuous-flow system. The levels of COD, phosphorus, and nitrogen removal in both systems were comparable but the biocenoses differed significantly. The SVI values of activated sludge from the continuous reactor ranged between 100 and 200 ml/g although no significant occurrence of filamentous microorganisms was observed. The sequencing batch reactor produced activated sludge with the SVIs below 100 ml/g and with high settling velocities. Filamentous microorganisms were frequently observed in the biocenosis of the SBR. The differences in settling properties and filamentous growth in both reactors are discussed and explained.

Abstract:

The research paper presents a comparative analysis of helminth fauna of American mink on the urbanized territories and natural biocenosis of the Kirov Region (floodplains of the Vyatka, Kama, Cheptsa and Moloma Rivers) in the north-east of the European part of Russia. The method of complete helminthological dissections was used to study 109 carcasses of American minks, including 70 minks of natural biocenoses and 39 urbanized landscapes of Kirov and other settlements of the Kirov Region. The extensiveness of the invasion and the intensity of the invasion were determined. The Student's criterion (t) was used to calculate the validity of differences at the significance level of 0.05. 18 species of helminths were revealed, of which five new species for the region including: Metorchis bilis, Crenosoma taiga, Mustelivingylus skrjabini. The basis of helminth fauna is biohelminths (87.5%). Rate of infection with helminths during the acclimatization period increased from 9.8 to 92.7%. Helminthofauna is represented by 7 species in urban areas. The dominant species are 5 helminths: Isthmiophora melis, Alaria alata, larvae, Aonchotheca putorii, Aonchotheca mucronata, Skrjabingylus nasicola. Females of natural biocenoses, as well as urbacenoses, are not infested with pulmonary helminths C. taiga and Trichinella spp. larvae. The extensiveness of infestation and the intensity of infestation in the American mink differ slightly from one habitat to another. The intensity of infestation of A. mucronata is higher in female mink living on the urbanized territories as compared to natural biocenosis. This difference has statistical significance (t=4.67, p ≤ 0.05). In settlements the intensity of infestation in males of I. melis and A. putorii exceeds significantly that of females (t=2.1-2.24 with a significance level of p ≤ 0.05). Epizootological and epidemiological hazards are represented by A. alata (larvae), Metorchis bilis and Trichinella spp.

Abstract:

The results of decades of comprehensive investigations of the undersea grounds of the Absheron Archipelago (the Caspian Sea), including landscape and bionomic zoning, which started in 1960ies, are overviewed. The five main types of undersea grounds and associated biocenoses are characterized with special attention to bivalve tanathocenoses associated with naked basement rocks. Based on these analyses, the leading role of geologic and geomorphologic structure of sea bottom in the development and distribution of natural complexes and biocenoses of sea bottom is suggested.

Abstract:

Abstract This article presents results of long-term monitoring of meadow biocenosis restoration after an oil spill and subsequent rehabilitation procedures at southern subtaiga territories of the Tyumen Region, Russia. The data obtained show that the measures taken fostered development of vegetation with high abundance and diversity of species. There passed 25 years after rehabilitation, and the succession stage of phytocoenosis at the affected area is not any more determined by pollution, but by bogging, a process characteristic of the unaffected biocenoses of the area under study. Secondary succession is also evidenced by more than a two-fold decrease in diversity and abundance of decomposer fungi species in a forest biocenosis adjacent to the area of oil spill. Such a decrease is conditioned by a reduced amount and variety of forest litter, that had been formed after the accident and was later humified by the fungi. In 2020, the ratio of the fungal species used as indicators of forest stand health prompted that the impacted forest was nearing its original condition. The terrestrial vertebrates communities have almost recovered over the period of monitoring, although there have appeared synanthropes, and the proportion of anthropophilic species has gone up.

Abstract:

Coastal marine areas are characterized by the highest values of ecosystem services and by multiple uses that are often in conflict with each other. Natural capital analysis is claimed to be a valid tool to support space planning. In the context of the Marine Strategy Framework Directive (MSFD) of the European Union (EU), the EU Joint Research Centre (JRC) Scientific and Policy Report 2014 defines the monitoring of specific descriptors and their possible use, based on an ecosystem-services approach. Mediterranean marine ecosystems are characterized by high biodiversity and the presence of relevant benthic biocenosis that can be used as a tool to support coastal planning, conservation, and monitoring programs. In this study, we considered the Mediterranean benthic biocenosis, as classified by Pérès and Picard, as a working tool and propose a basic spatial unit for the assessment of marine ecosystem services. Focusing on a high-resolution local-scale analysis, this work presents an accurate identification of the different biocenoses for the coastal area of Civitavecchia in the Northern Tyrrhenian Sea, Italy, and ecosystem services, as well as a benefits assessment, of the Posidonia oceanica meadows.

Abstract:

The soil mesofauna of the black alder forests of Kazakh upland is studied as an indicator of the functional features of Alnus glutinosa plantings on the southeastern border of the area. Forests do not form massifs of a large area and are associated with the type of relief, valleys of streams and rivers, and the groundwater. Relict species of flora and fauna testify to the ancient origin and importance of black alder forests as refugia. The forest communities are changing under the influence of recreational load and grazing. It requires an early assessment of the state of terrestrial biocenoses. It has been established that black alder forests are characterized by high total biomass of mesofauna (from 13,6 g/m2 to 42,1 g/m2), where more than 85 % of the zoomass falls on the saprophilic complex. The density of the soil population is significant (from 272,6 copies/m2 to 503,55 copies/m2), i.e., in general, forests retain the features of zonal broad-leaved formations. Anthropogenic changes in the structure of pedobionts in black alder forests associations at different stages of recreational and pasture digression are revealed. There is a consistent decrease in the density index of the soil population (P = 145,6; 80,19; 69,7) and the proportion of forest species. A change of life forms in the model (Carabidae) and dominant (Lumbricidae) groups, an increase in the number of zoophages, a decrease in the total number and depletion of the species composition of saprophages are noted. The soil mesofauna reflects in its structure the biocenosis originality of relict black alder forests of the steppe zone and the continuity of biocenoses.

Abstract:

Aim. To study the state of the marine ecosystem of the recreational‐tourist zone of the Caucasian sector of the Black Sea through the example of a beach near the mouth of the Agoy River.Material and Methods. Phytoplankton, heterotrophic bacterioplankton, infusoria, holoplankton, meroplankton, ichthyoplankton, zoobenthos of loose bottom sediments and hydrochemistry samples of the water and bottom sediments were collected in June 2012 on three sections from the mouth of the Agoy River to the coastal runoff zone (depths 2.5–7.5 m). The identification of species of plankton and of the zoobenthos and of the chemical parameters of water and sediments was carried out according to standard methods. Results. It was revealed that most of the beach area, where psammophilic biocenoses of Lucinella divaricate and Chamelea gallina (Bivalvia) were located, was in satisfactory condition. An increase in the density of Lucinella divaricate, a rare species in the late 1990s, was noted. In the runoff zone, there was observed the appearance of cyanobacteria and the suppression of zoobenthos, expressed through the replacement of mollusc biocenoses by the biocenosis of the polychaete, Capitella capitate, with a biomass two orders of magnitude lower than the average for the area. High numbers of heterotrophic bacterioplankton (4.5 million cell/ml) and infusoria (64 million ind./m3) could indicate bacterial contamination of this zone. The negative impact of waste water on plankton is manifested in a decrease in the population of netted zooplankton, their abnormal development, and the increasing role of microheterotrophs.Conclusions. The results obtained give an image of the state of marine coastal ecosystems of recreational‐tourist and cordoned areas of the Caucasus and can be useful for the further monitoring of this region.

Abstract:

Anthropogenic transformation of the Caspian Sea biocenoses results in the loss of their uniqueness and decrease of their biodiversity. In recent years the main role in the formation of biomass has played the autoacclimatizant mollusks Abra ovata , Mytilaster lineatus and Cerastoderma glaucum which dominate the biocenoses of the Caspian sea and are the main food components of valuable commercial benthivorous fishes. In 2018 live specimens of Corbicula fluminalis (O. F. Muller, 1774), a new species of bivalve mollusks for the Russian sector of the Caspian sea and the entire European part of Russia, were first discovered on the Daghestan coast.

Full text

Abstract:

Artificial stagnant aquatic ecosystems such as reservoirs, are suitable for monitoring the succession of biocenoses because they are usually formed by rearrangement of the former current river ecosystems. The weevil assembly, as part of such a dynamic biocenose, develops following host macrophytes. In the frame of weevil fauna studies realized during 2001 and 2002 in wet habitats beside four artificial lakes in Central Serbia (Gruza, Grosnica, Sumarice and Bubanj), the aquatic adults from 13 species, divided into two families, Eryrhinidae (Tanysphyrus lemnae and Notaris scirpi) and Curculionidae (Bagous bagdatensis, B. collignensis, B. lutulentus, Pelenomus canaliculatus, P. comari, P. waltoni, Phytobius leucogaster, Rhinoncus castor, R. inconspectus, R. pericarpius and R. perpendicularis), were collected. The quantitative and qualitative picture of the studied aquatic weevil assemblies, as well as indices of similarity among them, are given and related to the dimensions and ecological characteristics of studied aquatic systems (particularly the level of eutrophication).

Abstract:

The aim of the presented investigation was to describe seasonal changes of microbial community composition in situ in different biocenoses on historical sandstone of the Northern Pergola in the Museum of King John III’s Palace at Wilanow (Poland). The microbial biodiversity was analyzed by the application of Illumina-based next-generation sequencing methods. The metabarcoding analysis allowed for detecting lichenized fungi taxa with the clear domination of two genera: Lecania and Rhinocladiella. It was also observed that, during winter, the richness of fungal communities increased in the biocenoses dominated by lichens and mosses. The metabarcoding analysis showed 34 bacterial genera, with a clear domination of Sphingomonas spp. across almost all biocenoses. Acidophilic bacteria from Acidobacteriaceae and Acetobacteraceae families were also identified, and the results showed that a significant number of bacterial strains isolated during the summer displayed the ability to acidification in contrast to strains isolated in winter, when a large number of isolates displayed alkalizing activity. Other bacteria capable of nitrogen fixation and hydrocarbon utilization (including aromatic hydrocarbons) as well as halophilic microorganisms were also found. The diversity of organisms in the biofilm ensures its stability throughout the year despite the differences recorded between winter and summer.

Abstract The aim of this study of Aurès and Bibans (Tell) Cenomanian and Turonian series is the application of a sedimentological analysis in order to reconstruct the relationships between biocenoses, environments, systems tracts and depositional sequences. A quantitative approach has been developed including the study of variations of organism’s abundance in the sequences and in the palaeogeographic zones and the multivariate data analysis applied to the characterisation of biocenoses. These methods provide, compared to the results obtained by the more classical facies study, new informations about the evolution of the various organisms in the system tracts and their relations with the different palaeogeographic zones.

Abstract Activated sludge biocenoses were compared on waste-water treatment plants in the city of Kazan, Russian Federation and the city of Teplice, Czech Republic. Based on Palia-Kovnatski index, Acanthamoeba in Kazan, Epistylis in Teplice, and Acanthamoeba and Centropyxis were dominant genera in both plants. The major subdominant generas identified were Arcella, Opercularia and Aspidisca. This indicates high nitrification ability, high water purification potential and matured activated sludge. Chemical composition of the waste-water was identified as the main factor determining the sludge biocenoses diversity. Higher sludge biodiversity (Shannon, Margalef, and Sorensen indexes) was found in Kazan corresponding to more concentrated inflow water.

Abstract:

Today, in the context of industrial development, an integral part is the formation of wastewater with the need for its subsequent treatment. The biological method of wastewater treatment is the most effective, safe and reliable. This method is based on the work of activated sludge, which is a biocenosis of microorganisms that absorb pollutants from wastewater. Different quantitative and qualitative composition of wastewater and physical impacts can affect the work of the biological agent - activated sludge, therefore research in this area is relevant. To increase the efficiency of biological treatment, a number of methods are used, one of which is ultrasonic exposure of sludge to increase its biochemical activity. However, this approach requires studying its effect on activated sludge microorganisms. In this research work, the effect of ultrasonic exposure on flakes and biocenoses of activated sludge from treatment facilities of various wastewaters was studied and the change in the content of heavy metals after acoustic processing of sludge was determined.

Abstract:

This research aimed to gain a profound understanding of virtual biocenoses intricate digital ecosystems, with the goal of elucidating and replicating the emergence and evolution of intelligence in artificial creatures – referred to as noogenesis. A comprehensive analysis of existing studies within virtual biocenoses was undertaken to glean valuable insights into the complexities of modeling dynamic ecosystems where artificial agents engaged in intricate interactions. The pivotal role of neural networks in shaping the adaptive behaviors of artificial creatures within these environments was underscored. A meticulous investigation into neural networks' evolution methodologies revealed the evolution of their architecture complexity over time, culminating in the facilitation of flexible and intelligent behaviors. However, a lack of study existed in the domain of nurturing evolutionary-based communication and cooperation capabilities within virtual biocenoses. In response to this gap, a model was introduced and substantiated through simulation experiments. The simulation results vividly illustrated the model's remarkable capacity to engender adaptive creatures endowed with the capability to efficiently respond to dynamic environmental changes. These adaptive entities displayed efficient optimization of energy consumption and resource acquisition. Moreover, they manifested both intellectual and physical transformations attributed to the evolution and encoding principles inspired by the NeuroEvolution of Augmented Topologies. Significantly, it became apparent that the evolutionary processes intrinsic to the model were inextricably linked to the environment itself, thus harmonizing seamlessly with the overarching goal of this research. Future research directions in this field were outlined. These pathways provided a foundation for further exploration into the evolution of artificial creatures in virtual biocenoses and the emergence of advanced communication and cooperation capabilities. These advancements hold the potential to move artificial life and artificial intelligence to new levels of understanding and capability.

Abstract:

Sea level rise during the Pleistocene-Holocene transition period caused the formation of lagoon lakes along the western and eastern coasts of the Kuril Islands. These lakes include Lake Serebryanoye, located in the northern part of the South Kuril Isthmus near the Pacific coast of Kunashir Island (44°03'21" N; 145°49'46" E). The total thickness of sediments in the lake was 367 cm. They are characterized by diatom flora (334 species), representing various ecological groups: freshwater, brackish water, marine, marsh, lacustrine, rheophilic, planktonic, benthic. The analysis of diatoms made it possible to distinguish two complexes. As shown by radiocarbon dating, in the Middle Holocene (100.5-367 cm interval) the sediments corresponded to the lagoon stage, which changed in the Late Holocene (100.5-0 cm interval) to the freshwater lake stage. Palynological analysis showed a successive change of biocenoses, reflecting the development in the Middle Holocene of birch-broadleaved forests with the participation of Pinus koraiensis, Picea sp. The most abrupt change in biocenoses is observed at the boundary of the Middle and Late Holocene. This change of biocenoses is expressed by the dominance of conifers in the vegetation cover, represented by various species of Picea, Pinus, Abies, Larix. It also shows the relative cooling of the climate in the Late Holocene.

Abstract:

In the frame of a research project concerning regrowth problems a water utility at Lake Constance is involved. For this plant it was interesting to find out which effect is exerted by organic products released from algae living in the lake water. Therefore model experiments were carried out using two different algal cultures in the stationary phase, where the algae were carefully separated by filtration. From these extracellular organic carbon solutions (exudates) dilutions were prepared using highly purified deionized water. These were tested for their ability to support bacterial growth by adding a mixed bacterial biocenosis after sterile filtration and monitoring growth curves by turbidity measurements, a method developed at the DVGW-Research-Center in Karlsruhe to judge drinking water with respect to its regrowth potential. It was shown that the exudate from a Haematococcus culture is very growth stimulating, though the substrate concentration analyzed as ∆DOC was very low. In contrast the exudate from a Stephanodiscus culture gave a very low growth response. The effect of the Stephanodiscus culture for the drinking water plant at Lake Constance is much more important because Stephanodiscus is a species common in Lake Constance whereas Haematococcus is not.

Abstract:

The replenishment of our stock of substances that possess a therapeutic potential is an important objective in modern biomedicine. Despite the important advances achieved in chemical synthesis, the natural diversity of organisms and microorganisms remains an important source of biologically active compounds. Here, we report the results of our study of a unique collection containing more than 3,000 samples of yeasts found on the Kamchatka Peninsula, the Kuril Islands, and Sakhalin Island, Russia. Since yeast and bacteria coexist in a variety of habitats and can interact with each other, we analyzed the antibacterial activity of the collection of yeast strains towards E. coli cells using a fluorescent bacterial reporter. It was uncovered that the Sakhalin strains for the most part stimulate bacterial growth, while most of the strains found on the Kamchatka Peninsula possess inhibitory properties. Moreover, the samples with the most pronounced antibacterial activity, identified as members of the genus Cryptococcus (Naganishia), were found in a gorge in the vicinity of Pauzhetka village on the Kamchatka Peninsula on wormwood (Artemisia vulgaris) and thistle (Onopordum acanthium). Our data indicate that the combination of a plant and its growth site is important for the emergence of yeast strains capable of secreting antibacterial compounds.

Abstract In this article, we traced the development of fauna, bioecology and populations of more than 50 species of the main family Lepidoptera, found in the biocenosis of Uzbekistan. Research has been conducted in agricultural crops, forestry and natural biocenoses, and representatives of the Lepidoptera family have been involved in scientific research on species that cause great economic damage. Trichogrammatidae, Braconidae, Ichneumonidae, Chalcididae, Pteromalidae, and Tachinidae, the main entomophagous species that effectively control the number of members of the Lepidoptera family, have also been identified and systematically analyzed. The representatives of the family Trichogrammatidae, which are effective parasitic entomophagous in the management of the number of representatives of the family Lepidoptera. The study revealed that in the agrobiocenoses of cotton, mung bean, corn and cabbage in Tashkent province, the level of occurrence of three main species of nightshade pests of the family Trichogrammatidae, which are egg parasites of the family Lepidoptera, was determined. This means that the number of nights can be effectively controlled by members of the trichogramma family.

Abstract:

Ecologization of education is an integral part of the society’s renewal, which reflects and shapes its consciousness and newthinking. The formation of an ecological content at Biology lessons in high school is closely related to the formation of environmental competence. Expanding the content of the Biology course in high school with knowledge about the biocenosis and agrocenosis, based on science, will help to ensure the effective development of ecological “content line”. In the process of studying Biology in 10th grade, it is important to continue developing students’ cognitive interest, offering independent work with various sources of information: popular science literature, videos, Internet resources and more. We consider promising the development of ways to motivate the educational activities of students and the introduction of various forms of environmental education in schools during class activities. For example, conducting laboratory work on the analysis of species and trophic structure of the biocenosis with elements of scientific research willcontribute to the formation of deep ecological knowledge. One of the elements of the ecological competence formation process can be the performance of students' independent work, which involves compiling trophic chains examples and analysis of the trophic structure of biocenoses and agrocenoses different types. The proposed scientific and methodological advice on in-depth study and mastering the concepts of "biocenosis" and "agrocenosis" will form an ecological worldview and provide a basic level of high school students knowledge. Discovering the cycle of substances and energy flow, ensuring the stability and dynamism of natural and artificial biosystems and maintaining balance in the biosphere, are the scientific basis for the formation of students' environmental thinking, environmental responsibility and environmental skills.

Abstract:

In modern animal husbandry of Ukraine, there are still some unresolved issues related to the high number of zoophilic flies in the territories of facilities and the spread of animal infectious and parasitic diseases. A detailed study of bioecological peculiarities of the dominant zoophilic fly species contributes to improving the effectiveness of measures to control ectoparasites. 27 zoophilic fly species have been found in animal breeding complexes. The maximum number of parasitic Diptera species was recorded on cattle-keeping premises. The biological properties of Neomyia cornicina (Fabricius, 1781) (size, shape, colour, duration of preimaginal phase development) were studied. Also, we studied the dynamics of the number and daily activity of dominant fly species (Musca domestica Linnaeus, 1758, M. autumnalis De Geer, 1776, Stomoxys calcitrans (Linnaeus, 1758)). When studying the intraspecies competition, a high-degree survival of M. domestica and M. autumnalis was determined in the conditions of critical nutritional deficiency (0.5 g of nutrient medium per larva) and increased density of individuals (the imago emergence was 38.6% and 34.0%, respectively). In similar maintenance conditions, the emergence of N. cornicina imago was low (14.6%). With a two-fold increase in the insectarium volume and in the amount of nutrient medium (1 g per larva), the imago emergence of M. domestica, M. autumnalis and N. cornicina increased to 64.0%, 39.2%, and 24.0%, respectively. With an even greater increase in the amount of nutrient medium (2 g per larva), the maximum emergence of imagoes of all the studied fly species was observed (M. domestica, M. autumnalis, and N. cornicina: 96.6%, 91.2% and 72.6%, respectively). In the conditions of interspecific competition, M. autumnalis suppressed N. cornicina even in conditions of a sufficient amount of nutrient substrate. In the competition between M. domestica and M. autumnalis, house fly dominated. Increasing the nutrient medium volume narrowed the gap between the competing species.

Abstract:

The purpose of the research is to determine the relationship between the infestation of Cryptosporidium parvum in calves that have regular contact with synanthropic reservoirs (rodents and birds) in the climatic zones of Udmurtia. The study of the distribution and relationship of manifestations of cryptosporidiosis was carried out among calves that have regular contact with synanthropic rodents (gray rat (Rattus norvegicus), house mouse (Mus musculus), common vole (Microtus arvalis), bank vole (Myodes glareolus)) and birds (rock dove). (Columba livia), house sparrow (Passer domesticus), jackdaw (Coloeus monedula)). In total, 255 calves, 160 rodents and 80 birds were subjected to the study.The assessment of infestation of calves, rodents and birds was carried out by generally accepted coprological flotation methods, as well as by making native smears with further Ziehl-Neelsen staining. The results obtained were evaluated using statistical methods: analysis of variance, taking into account the Fisher criterion and the Pearson correlation coefficient.The results of the research showed that in all natural and climatic zones of the Udmurt Republic a high percentage of infection with cryptosporidiosis of calves is recorded.On the territory of the southern zone, the infection rate of calves with cryptosporidiosis was 62.35%, while in captured mouselike rodents the prevalence of invasion was at the level of 37.25%, and in birds - 20.0%.In the farms located on the territory of the northern natural and climatic zone of the republic, the degree of infestation of calves reached 41.18%, the infection of rodents was 23.91%. The minimum percentage of detection of cryptosporidium oocysts among synanthropic birds was observed in the north of Udmurtia - 11.77%.The fact of the dependence of the invasion by the causative agent of cryptosporidiosis of calves on the presence of parasite carriers in farms has been established. According to the results of calculating the correlation coefficient and analysis of variance, a direct close relationship was revealed between the infection of calves and representatives of the synanthropic reservoir - rodents, birds, regularly in contact with agricultural crops. animals.

Abstract:

Formulation of the problem. The problem solved in the article is relevant primarily due to the constant growth of the density of the transport network, and, therefore, the ever-increasing "theft" of natural ecosystems by humans from aboriginal plants and animals. However, new alien plants, which are gradually displacing local species, are able to form completely independent biocenoses, which proves the extraordinary ability of the biosphere to support life. The purpose of the article to investigate the formation of biocenoses in the vertical structure of roadside landscapes of Cherkasy Region. Methods. The main theoretical approach to identifying human-made landscapes, including linear ones, in this study is based on the prioritization of ecosystem dynamics. This approach emphasizes the maintenance or enhancement of the ability of ecosystems to maintain their natural processes and functions over time. General scientific and specific scientific methods of geographical research were applied. Especially important for the implementation of the tasks are the methods of geobotanical research. Results. The study of the main parameters of the roadside landscapes of the Cherkasy Region was carried out by us in accordance with the pre-developed program. All parameters were combined into the following groups of factors: natural-geographic factor (geolocation, air temperature and humidity, natural radiation background); the degree of anthropogenic impact (noise level, dustiness, some geochemical indicators, proximity/distance of the roadway from agricultural land); the degree of manifestation of ecosystem relations (the number of plant species and their recurrence, the presence of invasive species and those that are indicators of salinization and waterlogging, the presence of species included in the National Catalog of Biotopes of Ukraine, the value of the Menkhinik index (species diversity). Using the method of petal diagrams, as well as the method of qualitative background, an analysis of the entire set of parameters for each polygon was performed, which made it possible to identify 5 districts of different degrees of completeness of the formation of ecosystem relations in the territory of the Cherkasy Region. Two core regions - Umansky (medium degree) and Cherkasy (low degree), the main characteristics of which are dominated by different parameters of ruderal vegetation, and three peripheral areas, in which the parameters of ruderal vegetation are below the average level - North-peripheral (Zhashkivskyi, initial degree), South-peripheral (Ladyzhynskyi, elementary level), and Central-peripheral (Zvenigorodsko-Shpolianskyi, elementary level). In general, the conducted zoning covers only those sections of highways that directly border agricultural lands. But due to the presence of mainly herbaceous vegetation in such ruderal phytocenoses, they can be the basis of future soil formation with further gradual cultivation by replacing ruderal plants with aboriginal ones. Scientific novelty and practical significance. Studies of the biodiversity of Cherkasy Region in the territories covering biocenoses formed along the Kyiv-Odesa (M 05) and Vinnytsia-Cherkasy (M 12 and H 16) highways showed that there is almost no native vegetation. Instead, roadside biocenoses mainly consist of ruderal plant species. The scientific novelty lies in the fact that the zoning of highways in the Cherkasy Region has been carried out according to the degree of completion of the formation of ecosystem relations in roadside landscapes.

Abstract:

The article is devoted to a review of the topical problem of our time “Microbiocenosis of open cavities of the body and its role in the occurrence of many diseases of the human body ”. It has now been proven that the normal microflora of the human body plays a huge role in the normal course of life processes. The slightest violation of the composition of microorganisms leads to various irreversible defects in the normal course of human life, which are associated with the functions of the microbiocenosis and which no medicine can replace. The concept of microbiocenosis appeared in the 70s of the last century, although the first stone in this direction was put by Louis Pasteur, who proved the role of a microorganism in the process of fermentation and digestion. Many scientists contributed to the leap forward development of this science, which was forced due to errors in the use of antibiotics and chemotherapeutic drugs. Yes, indeed, the path of development of the science of biocenoses is closely related to the misuse of drugs, which often leads to dysbiosis. In addition, environmental pollution due to the uncontrollable development of urbanization plays a huge role in the development of dysbiotic processes.Therefore, with the aim of acquainting readers with the concept of biocenoses, certain pathways of pathogenetic links in the development of various diseases in violation of the composition of the normal microflora of the human body, we set ourselves the task of conducting a partial review of the achievement of the science of biocenoses of open cavities of the body.

Abstract:

The soil discharges made by moles (molehills) consist of mixed superficial soil layers where the main physicochemical parameters of soil show beneficial changes, including reduced density, moisture and acidity and increased humus content, especially during the first three months after molehill formation. In the present study, the biocenoses most preferred by the European mole (Talpa europaea, L) in Vologda Region have been determined. Most avidly inhabited by moles were moistened areas at forest edges and mixed young growths on glades. A limiting factor of the excavating activity of moles is soil grain-size composition. Moles prefer light and middle- density loams where its activity is high than in areas with light sandy loams and heavy loams. Data on the areas modified by moles in different sylvan biocenoses have been obtained. A positive effect of mole activities is facilitating the beneficial conditions for the restoration of plant communities destroyed by deforestation.

The article reflects the essence of the concept of "succession", describes the work on the formation of environmental knowledge in primary school children through the study of succession in the wild, presents the results of the experiment, clearly demonstrating positive changes in indicators in the field of environmental knowledge.As is known, succession is a natural sequential change in the ecosystem, in which one biocenosis in a given area of the lithosphere is gradually replaced by another. If the conditions for the change of biocenoses are not violated by external factors, the succession is directed, predictable. Although physical factors determine the nature of succession, it is controlled by the biological community. The conducted pedagogical experiment speaks about the effectiveness of the use of visual. Elementary school children were able to learn about the concept of "succession," despite the fact that this topic is not usually taught in elementary school.

Abstract:

The problem of waste disposal of poultry production is considered. The properties of bird droppings are analyzed, depending on the condition and feeding of the bird. The morphological composition of poultry manure is given, and the value of 1 ton of bird droppings to mineral fertilizer is compared. Bird droppings has a feature – a narrow ratio of carbon and nitrogen, that’s why the litter is mineralized much faster by the soil microflora. It is also emphasized that wrong storage of bird droppings leads to loss of nitrogen, which can reach 50%. Various technologies for disposing of droppings by microorganisms are considered, using the California worm and housefly larvae. Bioenergetic methods of litter utilization are analyzed in detail. The article comprehensively examines the processes of anaerobic fermentation of manure and the production of biogas-methane, notes the dependence of biogas formation on temperature, and emphasizes that mesophyll and psychophile bacteria participate in the formation of biogas. Then the biogas is used to generate electricity and heat the premises. In addition to thermo and mesophilic fermentation, the disposal of bird droppings using vermiculture and red housefly is considered. The positive aspects of these technologies are described, namely, the production of biohumus, which binds and neutralizes heavy metals, in the process of utilization, phytohormones are produced by microflora, being used in crop production, they accelerate the growth of plants by 4-6 times, help to resist diseases and pests of agricultural crops. The article notes the high effect of using the larvae of the house fly (Musca domestica L), which was thoroughly tested by the Federal Science Center of Animal Husbandry under the guidance of academician L.K. Ernst. The high efficiency of using fly larvae is emphasized, where scientists note that in addition to the membrane and intracellular mechanism of digestion, induced autolysis is added (joint digestion of food by the "host" and "victim" enzymes in the host's gastrointestinal tract). Specialists get chitin and chitosin of high quality from fly larvae. Derivatives of these compounds are used in the food, perfume, pharmaceutical, and medical industries, moreover, chitosin is the polymer of the future. It increases the resistance of animals to infectious diseases by 10-15 %.

Abstract:

SummaryDespite the fact that bacteria of the genus Bacillus isolated from the soil have been studied for centuries, there are still topics that are not sufficiently covered or need further research. Most often, members of the genus Bacillus are isolated from soil or food. In recent years, these bacteria have begun to isolate from various aquatic biocenoses of ecosystems of oceans, seas, estuaries, lakes, rivers. Studies of such isolates indicate that bacteria of almost all species of the genus Bacillus are infected with bacteriophages of the order Caudovirales, which have caudal processes, integrase and excision systems necessary for the lysogenic development cycle. Although most of the bacteriophages found belong to the order Caudovirales, they have a wide range of differences, such as the relationship to temperature and pH, the impact on metabolism and sporulation of the host. The review presents data from the modern literature on bacteriophages that infect bacteria of the genus Bacillus isolated from aquatic biocenoses, features of their structure, chemical composition, genome structure and interaction with the host cell.

Abstract:

Highly productive meadow grass communities are a valuable biological resource used in agricultural production. To date, there are several main forms of using natural meadows in agriculture – this is haymaking and grazing. The paper presents the results of a comparative analysis of the biological production of aboveground phytomass of four representative sites of floodplain meadows located in Semiluksky, Ternovsky, Talovsky and Bogucharsky districts of the Voronezh region. The study covers a five-year period from 2019 to 2023. The results of the study show differences in the peak values of the aboveground plant biomass of meadows in different regions of the region, as well as the difference in the timing of the formation of the maximum biomass from the beginning of spring vegetation. Based on the results of the study, conclusions are drawn about the prospects of using the biological resource of meadow phytocenoses in the agricultural production of the region, as well as its scaling. Keywords: BIOLOGICAL RESOURCE OF MEADOW BIOCENOSES, DYNAMIC OF PRODUCTIVITY OF MEADOW BIOCENOSES, REMOTE MONITORING, FEED AND ENERGY VALUE

Abstract:

New data on the species composition and distribution of phytoseiid mites (Parasitiformes, Phytoseiidae) in plant associations of the National Nature Park “Ichnyansky” were obtained. Twenty species from 9 genera of the family Phytoseiidae are recorded: Amblyseius andersoni, Amblyseius herbarius, Amblyseius obtusus, Amblyseius rademacheri, Neoseiulus danilevskyi, Neoseiulus reductus, Neoseiulus zwoelferi, Euseius finlandicus, Kampimodromus aberrans, Kampimodromu corylosus, Dubininellus echinus, Dubininellus juvenis, Typhloctonus tiliarum, Amlydromella halinae, Amlydromella pirianykae, Amlydromella rhenana, Amlydromella clavata, Amlydromella verrucosa, Typhlodromus laurae, Galendromus longipilus. The calculation of the occurrence index (P1, %) of the identified species of phytoseiid showed that its maximum value is observed in E. finlandicus. This species is also the most numerous in the total number of collected specimens in the sample. Kampimodromus aberrans, D. juvenis, G. longipilus, K. corylosus, N. danilevskyi, N. zwoelferi and T. tiliarum should be considered as the most rarely encountered species with index of occurrence of 1.3%. The remaining species have intermediate values of this index. The analysis of literature data on the occurrence of phytoseiid species with the highest value of the index of occurrence (E. finlandicus, A. pirianykae and A. andersoni) in the plant associations of adjacent zones (Polesie and Steppe Zone) allowed us to reveal some regularities. In Polesie, E. finlandicus (Kolodochka, 2011) is the most common species. In the Steppe zone, E. finlandicus also has a high index of occurrence and is the third most common species of predatory phytoseiid mites. Such a high occurrence of this species is caused by a wide range of its potential victims. Euseius finlandicus is an euribiont, however more adapted to shrub vegetation. The decrease in the occurrence index of this species from Polesie to the Steppe Zone is explained by changes in the moisture content of biocenoses, as well as due to the gradual replacement of tree-shrub vegetation of grass. Amlydromella pirianykae and Amblyseius andersoni are found mainly on herbs. The detection of these species on trees and shrubs should be considered as incidental finds. The characteristic biocenoses for these species are the wet bayrachnye forests, floodplains of rivers, meadows. When choosing a biocenosis for habitat, humidity plays a key role. The analysis of the phytoseiid mites species complex in the plant associations of the Ichnyansky National Natural Park showed the presence of one dominant species, one subdominant, five types of first order subdominant and 13 minor community members in the community.
