The necessity to increase soil fertility by identifying their critical condition, which is associated with developing erosion processes, increasing acidity and decreasing humus, has been proven in the article. The requirement of introducing crop rotations and their legal regulation in Ukraine has been determined. The practice connected with the questions of supporting soil quality and crop rotations in different countries, members of the EU has been presented. The assessment of modern farming systems (intensive, organic, no-till, strip-till, precise, bio-enzyme, biogenic) taking into account economic, ecological, technological-energy, and social factors aimed at determining their impact on the natural soil fertility has been conducted. The expediency of improving soil quality in terms of its evaluation has been revealed. The necessity of introducing economic incentives or penalties to landowners or land users for agro-ecological condition of farmlands basing on the methods of land money value has been substantiated.

In southern Atlantic studies on hermit crab biology are scanty considering the local biodiversity. In this way, some population features of Paguristes calliopsis Forest and Saint Laurent, 1968 such as size frequency distribution, sex ratio and shell occupation in the natural environment were studied. Specimens were collected by means of scuba methods in the infralittoral area of the Anchieta Island. A total of 116 individuals were analyzed. Size measurements (minimum; maximum; mean shield length ± sd, respectively) were 0.8; 4.5; 2.76 ± 0.79 mm for males and 2.28 ± 0.36 mm for females. The sex ratio was 1.47:1 in favor of males which prevailed in the largest size classes. The hermit crabs occupied shells from eleven gastropod species and Cerithium atratum (Born 1778) was significantly the most occupied one (75.86%). Significant correlations were not obtained in all regression analysis, demonstrating sexual differences on fitting of the occupied shells. In the studied area P. calliopsis population is small if compared with the other hermit crab populations. The shell utilization varies as a function of shell availability and hermit crabs interspecific competition, in relation to the other coexistent species.

Social innovation is a community empowerment activity based on the community’s social needs to encourage the improvement of capabilities and social relations, as well as better utilization of assets and resources. Social innovation based on bio cyclo farming system aims to introduce the community to environmentally friendly agricultural businesses. This study aims to 1) analyze social innovations based on bio cyclo farming, 2) measure the impact of bio cyclo farming on social, economic, and ecological aspects, including contributions to achieving the SDGs. This research was conducted using qualitative methods supported by quantitative data. The social innovation analysis method includes aspects of the fulfillment of community needs, the element of novelty as a solution to community problems, the existence of social change, and the increase in community capacity. The research location is in Majalengka Regency. The results showed that bio cyclo farming was implemented through agricultural waste and household waste into agricultural inputs, optimization of the use of vacant land, and development of a businessoriented agricultural system. The economic impact of this community empowerment program includes producing several organic products that provide additional assistance to the group. The social impact of the program can be seen in the formation of new institutions, the change in science and skills, and the increasing cohesiveness of society. The perceived environmental impact is in the form of using agricultural waste and household waste as well as optimizing the use of vacant land. Bio cyclo farming-based community empowerment also contributes to achieving the SDGs, especially waste management and food security.

Secondary metabolism plays an important role in the adaptation of plants to their environments, particularly by mediating bio-interactions and protecting plants from herbivores, insects, and pathogens. Terpenoids form the largest group of plant secondary metabolites, and their biosynthesis and regulation are extremely complicated. Terpenoids are key players in the interactions and defense reactions between plants, microorganisms, and animals. Terpene compounds are of great significance both to plants themselves and the ecological environment. On the one hand, while protecting plants themselves, they can also have an impact on the environment, thereby affecting the evolution of plant communities and even ecosystems. On the other hand, their economic value is gradually becoming clear in various aspects of human life; their potential is enormous, and they have broad application prospects. Therefore, research on terpenoids is crucial for plants, especially crops. This review paper is mainly focused on the following six aspects: plant terpenes (especially terpene volatiles and plant defense); their ecological functions; their biosynthesis and transport; related synthesis genes and their regulation; terpene homologues; and research and application prospects. We will provide readers with a systematic introduction to terpenoids covering the above aspects.

Sea turtle conservation management is part of natural tourism activities which are often referred to as ecotourism based on bio-ecoregion. Conservation activities by taking into account environmental, socio-cultural and economic aspects receive special attention by the community, especially sea turtle conservation. In Indonesia, one of the areas that conducts sea turtle conservation in Bali. This research aim to analysis the role of sea turtle conservation education for sustainable marine tourism based on bio-ecoregion (Case Study in Bali, Indonesia). The method used in this research is quantitative descriptive. The data used in this research primary and secondary data. The data collection technique used purposive sampling with 60 respondents consisting of tourists. Based on the research results of sea turtle conservation management in Bali tourism area from the ecological, social and institutional aspects it has a low value while from the economic aspect it has a high value. Lessons learned from the management of sea turtle conservation in Bali by emphasizing the socio-cultural aspects are able to produce modern sea turtle conservation management with the concept of ecotourism based on bio-ecoregion and able to improve the economy of the local community. The results of the activity showed that tourists who visit the sea turtle conservation area are provided with information about the sea turtle population that has decreased and is included in the protected animals. Conservation education aims to introduce tourists to raising awareness of the sustainability of sea turtle resources.

Mangrove forests in Aceh are significant because of their roles in ecological, socio-economic, and socio-cultural aspects. Mangrove restoration efforts must be based on adequate land assessment and regular evaluation of the viability of planted mangroves. Therefore, this study aimed to analyze the bio-ecological characteristics of mangrove planting locations and evaluate land suitability in the restoration areas in Aceh Besar (Layeun Village) and Aceh Jaya (Babah Ie, Ujong Sudeun and Keude Unga Villages). This study was conducted in the YAGASU restoration area in Aceh Besar and Aceh Jaya Regencies in September 2022. The primary data consisted of the physicochemical characteristics of the environment, biodiversity, land suitability index, and plant survival rates after 3- 6 months planted. Data were analyzed using correlation, principal component analysis (PCA), cluster analysis (CA), descriptive statistics, and land suitability index. The result showed that the physical-chemical parameters of the environment are suitable for supporting the growth of mangroves and the livelihoods of various communities. In the study areas, the communities include 8 mangroves, 15 fish, 19 benthic, 11 zooplankton, and 22 phytoplankton species. Layeun, Ujong Sudeun, and Keude Unga Villages were found to have better land suitability than Babah Ie Village. However, an evaluation of the results of planting monitoring showed that Layeun has the highest survival rate compared to the other three villages. The results showed that pests, including buffalo and crustaceans, as well as sea waves, and the duration of the tides inundating the water are the main factors causing mangrove mortality.Keywords:Mangrove restorationSuitabilityBio-ecological

Bio-swales have gained significant attention as an effective means of stormwater management in urban areas, reducing the burden on conventional rainwater management systems. Despite this increasing interest, a comprehensive assessment of the status of bio-swale research is lacking. In response, this article employs two powerful information-visualizing software tools, the “Bibliometrix” R package and “CiteSpace”, to conduct a quantitative investigation of 323 English language sources published in the Web of Science prior to 2022. The objective is to provide a comprehensive examination of bio-swale research from multiple perspectives, shedding light on current advancements and future research trends. The findings reveal (1) a persistent annual increase in bio-swale-related publications and (2) the predominant focus on regulating services, such as hydrology, water quality, and biodiversity, with hot topics within these areas, including the influencing factors, climate, modeling, soil contaminants, and biodiversity at both macro and micro levels. Furthermore, our study concludes that future research necessitates interdisciplinary and interterritorial collaboration, a broader focus that encompasses the social, economic, ecological, and engineering aspects of bio-swales, and the adoption of diverse research methodologies. Given the currently limited research on biodiversity in bio-swales, this area holds the potential to become a future research hotspot. By harnessing the insights and findings of our study, researchers can gain a more profound understanding of the current state of bio-swale research and devise effective strategies to further propel this critical area of study.

In recent years, scientific methods of bio- and geoarchaeology have become increasingly important for archaeological research. Political changes since the 1990s have reshaped the archaeological community. At the same time environmental topics have gained importance in modern society, but the debate lacks an historical understanding. Regarding medieval rural archaeology, we need to ask how this influences our archaeological research on medieval settlements, and how ecological approaches fit into the self-concept of medieval archaeology as a primarily historical discipline. Based mainly on a background in German medieval archaeology, this article calls attention to more complex ecological research questions. Medieval village formation and the late medieval crisis are taken as examples to sketch some hypotheses and research questions. The perspective of a village ecosystem helps bring together economic aspects, human ecology and environmental history. There are several implications for archaeological theory as well as for archaeological practice. Traditional approaches from landscape archaeology are insufficient to understand the changes within village ecosystems. We need to consider social aspects and subjective recognition of the environment by past humans as a crucial part of human–nature interaction. Use of the perspective of village ecosystems as a theoretical background offers a way to examine individual historical case studies with close attention to human agency. Thinking in terms of human ecology and environmental history raises awareness of some interrelations that are crucial to understanding past societies and cultural change.

The socio-economic benefits derived from impounding rivers are extremely important but the ecological imbalances that are usually created in the process can be devastating. It is therefore imperative to understand some aspects of the biology of fishes before the impoundment of a river. This study was conducted to assess the length-weight relationship, condition factor, feeding, and reproductive ecology of fish species with high local market value. Biometric measurements were obtained from monthly samples of fish at two sites. Specimens were transported to the laboratory for gut and gonad analyses. Auchenoglanis occidentalis, Marcussenius senegalensis and Heterobranchus bidorsalis were the most preferred fish species. All three fish species recorded ‘b’ values less than 3 which implies they exhibited a negative allometric growth. Their condition factors (K) indicated they were in good health since K values were greater than 1. A. occidentalis and H. bidorsalis demonstrated a feeding habit comparable to that of an omnivore, whilst M. senegalensis presented a feeding habit that implied it was an invertivore. M. senegalensis registered the uppermost mean gonado-somatic index (GSI) (2.14 ± 0.83) whereas the highest mean fecundity (495 ± 450.96) was noted in A. occidentalis. This study contributed bio-ecological baseline information about the ichthyofauna prior to the damming of the reservoir in the Pwalugu area of the White Volta.

The largest part of forest biomass consists of wood. A global estimate of carbon stored in lignified tissues rises up to 400 Pg. Given these quantities, there is a growing interest of implementing wood research in diagnoses and evaluations of the carrying capacity of the global ecosystem and its forests. The question arises how disciplines like wood anatomy could respond to the increasing demands of a trait-based ecology, understood as a paradigmatic shift in addressing global changes. Dendrochronology and ecological wood anatomy, traditionally operating within the paradigm of species-based ecology, developed robust methods to address ecological questions. However, sampling strategies and database design will likely be different when wood traits are to be used to study individual tree performance, including responses to stress.Aiming at optimally involving wood research in trait-based ecology, some trait concepts are analysed. The value of the IAWA standard lists of wood anatomical features as starting points for trait databases is recognized. A summary of the functionality of wood is given to inform the trait-research community of basic aspects of tree performance. The time dimension is highlighted, as well as the foundations for understanding bio-hydraulics, bio-mechanics and metabolism of wood and relevant traits.Guidelines are given for sampling strategies and database concepts. Prospects of time axis construction and system integration are discussed, as well as the importance of standardizing for size.

This study reviews the available and most commonly used methods of gas deodorization. Comparing various methods of odor removal, undoubtedly biological methods of pollution degradation have an advantage over others—chemical and physical. This advantage is manifestedmainly in ecological and economic terms. The possibility of using biological methods to remove H2S and NH3, as the most common emitted by the municipal sector companies, was analyzed in terms of their removal efficiency. The method of bio-purification of air in biotrickling filters is more advantageous than the others, due to the high effectiveness of VOCs and odors degradation, lack of secondary pollutants, and economic aspects—it is a method competitive to the commonly used air purification method in biofilters.

investigated the economic, ecological-environmental and social functions of rural development in communities bordering the Hortobágy National Park, such as in Balmazújváros, Hortobágy, Tiszacsege and Egyek. My purposes focused on four issues: (1) to work out a method on the basis of the examined and cited literatures, which defines the development of communities from economic, ecological and social aspects of rural development; (2) to reflect the changes in the role of agriculture; (3) to analyse the effects, advantages and disadvantages of Hortobágy National Park in relation to the economic, ecological and social lives of the examined communities; and (4) to make an economic analysis on the alternative income sources of Hortobágy, such as rural tourism, herb production and bio-farming in a family farm structure. When measuring the development of the communities I concluded that complex indexes hide the real consideration of the three functions of rural development and the possibility for comparing them on a community level. Furthermore, these 19 indicators are not enough to evaluate the situation, thus I raised the number of indicators and handled them on the basis of the three functions of rural areas. I classified the economic, ecological and social indicators into indicator groups within each functions, which make the determination of causes for underdevelopment possible. While only Tiszacsege and Egyek were considered to be backward on the basis of the complex index of the Hungarian Central Statistical Office, my investigations showed that even Balmazújváros and Hortobágy proved to be lagged behind from both economic and social aspects. The methodical development justified the hypothesis that few indicators are not enough to establish decisions objectively. New developmental orders emerged. Measuring development of communities may be all-rounded and more established by using this new method, which may result in objective preparation of decisions in rural development and more rational spreading of subsidies.

The rehabilitation of legacy mines continues to be a big challenge because of the difficulties in returning them to safe and stable conditions and ensuring that the mined-out areas become productive to support the economic activity of the host community. Previous efforts are often focused on purely technical and environmental aspects, leading to resistance from the local community due to their exclusion from the rehabilitation process. To address the issues associated with legacy mines and lack of participation of the community, we have developed a project, Biodiversity Positive Mining For The Net Zero Challenge (Bio + Mine), focusing on the abandoned Sto. Niño copper mine (Benguet, Philippines). The mine was closed in 1982 without a plan involving local stakeholders and leaving a significant ongoing negative legacy. Using the social-ecological-technological system framework, we will explore the intersections of the structure and functions of socio-economicdemographic, ecological, and technological data useful in devising a more inclusive mitigation strategy for the reconstruction of the supporting ecosystem. We aim to develop a site-specific system, underpinned by the local community's knowledge and practices, that can be a model for wider implementation in other legacy and active mines worldwide.

Following this vision, the use of bio-laden animal based polymers derived from a mode of production by implementing optimization practices respectful of natural resources sustainably, has become changing way of thinking largely replace the use of non-renewable resources for human activities, the depletion of fossil resources deposits and to fight against the impact of climate change generated by this practice. Our paper attempts to analyze first the mechanical behavior of a bio-load and then incorporated into a polymer material to test improved mechanical and thermal characteristics made to it after adding and optimizing subsequently, its use. This is a load in the form of powder or chips extracted from an animal sheath. Tensile tests are performed in a first step, in order to mechanically characterize the virgin material and eco-composite obtained after the combination, i.e. the maximum tensile strength, the relative deformation and the modulus of the elasticity, etc

In the world, the traditional agricultural practices are getting affected by various problems such as disease, pest, drought, decreased soil fertility due to use of hazardous chemical pesticides, pollution and global warming. As a result, there is a need for some eco-friendly bio-control agents that help in resolving the previous mentioned problems. The various types of biological control agents such as bacteria and fungi are involved in bio-control activity. Among them, fungal genus Trichoderma plays a major role in controlling the plant diseases. Species of Trichoderma are diverse fungal microbial community known and explored worldwide for their versatilities as biocontrol and growth promoting agents. These fungi reproduce asexually by production of conidia and chlamydospores and in wild habitats by ascospores. Trichoderma species are efficient mycoparasites and prolific producers of secondary metabolites, some of which have clinical importance. However, the ecological or biological significance of this metabolite diversity is sorely lagging behind the chemical significance. Several Trichoderma spp. positively affect plants by stimulating plant growth, and protecting plants from fungal and bacterial pathogens. They are used in biological plant protection as bio-fungicides as well as in bioremediation. A large number of research groups are working on various aspects of Trichoderma viz., diversity, ecology and their applications. The capacity of Trichoderma fungi to produce lytic enzymes is used in animal feed, and wine making and brewery industries. Trichoderma spp. are the most successful bio-control agents as more than 60% of the registered bio-fungicides used in today’s agriculture belongs to Trichoderma -based formulation. The increase in incidence and severity of diseases and emergence of new diseases causes the significant yield losses of different crops in Nepal. But the research and studies on plant diseases are limited.

Advances in research concerning the brain-related influences of the microbiome have been paradigm shifting, although at an early stage, clinical research involving beneficial microbes lends credence to the notion that the microbiome may be an important target in supporting mental health (defined here along the continuum between quality of life and the criteria for specific disorders). Through metagenomics, proteomics, metabolomics, and systems biology, a new emphasis to personalized medicine is on the horizon. Humans can now be viewed as multispecies organisms operating within an ecological theatre; it is important that clinicians increasingly see their patients in this context. Historically marginalized ecological aspects of health are destined to become an important consideration in the new frontiers of practicing medicine with the microbiome in mind. Emerging evidence indicates that macrobiodiversity in the external environment can influence mental well-being. Local biodiversity may also drive differences in human-associated microbiota; microbial diversity as a product of external biodiversity may have far-reaching effects on immune function and mood. With a focus on the microbiome as it pertains to mental health, we define environmental “grey space” and emphasize a new frontier involving bio-eco-psychological medicine. Within this concept the ecological terrain can link dysbiotic lifestyles and biodiversity on the grand scale to the local human-associated microbial ecosystems that might otherwise seem far removed from one another.

The tropical ecosystem had high biomass productivity but still less in economic values. Integrated Bio-cycle Farming System (IBFS) was an alternative system that harmoniously combines agricultural sectors (agriculture, forestry, animal husbandry, fishery, plantation estate, horticulture) and non-agricultural aspects (industry, household, infrastructure, the marketplace) on integrated ecological management. The key characteristics of IBFS developed in UGM University Farm were (i) an integration of agriculture and non-agriculture sector, (ii) value of environment, esthetics and economics, (iii) rotation and diversity of plants, (iv) artificial and functional biotechnology, (v) management of closed organic cycle, (vi) ecosystem health management, (vii) agropolitan concept, (viii) specific management of plant and (ix) holistic and integrated system. The management of cycle of energy, organic matter and carbon, water, nutrient, production, crop, money conducted through 9R (reuse, reduce, recycle, refill, replace, repair, replant, rebuild, reward) to obtain optimal benefits for global environment and livelihood. The system had a sustainable multifunction and multi-product (food, feed, fuel, fiber, fertilizer, biopharma, water, energy, oxygen, edutainment, eco-tourism). They would meet the expected basic need for daily-, monthly-, yearly- and decade’s income at short-, medium- and long- term periods. IBFS was a good prospect for sustainable economic, environmental, and socio-culture aspects.

<abstract> <p>The economic concept of the circular bioeconomy addresses not only the sectors of the traditional bioeconomy but also, in particular, the sectors of bio-based chemicals and energies as well as waste management. This concept is basically based on closing material cycles, in particular, but not only, that of carbon. Managing these material cycles is costly, which is why economic sustainability and, in the current transition phase, competitiveness with fossil-based value chains remain a constant challenge. Because of the large material turnover of the mentioned industries, in the interest of environmental sustainability the circular bioeconomy has to respect the limits of natural resources. With the raw material shift from fossil to renewable resources, regional economic structures and jobs will change and, in addition, circularity requires a change in consumption behavior. Both are challenges that need to be addressed in the interest of social acceptance and sustainability. The article focuses on the economic, but addresses also the ecological and social aspects, discusses options for achieving a comprehensively sustainable circular bioeconomy, and identifies research needs necessary for the further development of the bioeconomy.</p> </abstract>

The study of interpersonal aggression has been carried out for the most part in separate spheres by experts from an array of academic disciplines. To advance a deeper understanding of these issues, however, requires a more conciliatory and interdisciplinary approach. The article offers just such an integrated approach, using a multi-level heuristic framework that has direct parallels with ecological modeling. In addition, the approach expands the analytic focus to reflect different aspects of complex human behavior, which include: 1) the behavioral investment framework, or the bio-psychological reality of the human animal; 2) the socialization framework, or the social psychological aspects of human learning and development; 3) the justification framework, or the language, knowledge, and meaning systems that one acquires to facilitate interpersonal communication and to justify one’s actions; 4) the social location framework, or the social interactional dynamics of interpersonal relationships that animate one’s daily life as a member of various groups and social networks; and 5) the societal context framework, or the broader institutional forms and sociocultural conditions within which individuals and groups are situated. The current approach bridges human neurophysiology and psychology with sociology in a developmental, ecological context that examines each dimension of human behavior. While the five dimensions can be separated analytically, in practice these overlap to exert multiple influences. Such a conciliatory framing permits a more comprehensive analysis of human social animals as situated within their natural environments. The paper outlines how each of the five levels contributes to expressions of interpersonal aggression by elaborating on key mechanisms that operate across the different levels of informational complexity. Several examples of empirical research are cited to illustrate the core principles that operate within and across the five complementary frameworks. Keywords: interpersonal aggression, violence, ecological model, integrated framework

Phomopsis incarcerata, known as the pathogen which caused the dieback of Rosa branches was detected in many orchards in Romania. Our investigations have approached a series of bio-ecological aspects of this pathogen: isolation, purification and obtaining the pathogen; determination and identification of the pathogen; establishing in vitro parameters of fungal development (nitrogen source). The isolate used in this study was obtained from Rosa spp. branches and was cultivated on three culture media: potato dextrose agar (PDA), malt extract agar and water agar which included five amino-acids: cysteine, glycine, beta-alanine, leucine and tryptophan. Leucine and glycine were favorable for the dynamics of the fungus.When the fungus grew on water agar, the sporulation was completely inhibited. The optimum pH values for the growth and creation of the Phomopsis incarcerata are in the range of 4.4-7, so weak to neutral acid.

According to European agreements, many WWTPs (waste water treatment plants) have to be modified and extended to reach stricter effluent standards with regard to phosphorus and nitrogen. This paper presents the modification of a 300,000 p.e. WWTP. The following steps are distinguished: location/centralization study, process pre-selection, pilot tests and process control. Most important aspects in the location study are costs and ecological importance of the receiving water. In the process pre-selection study two nitrogen and phosphorus removal processes were selected: a high cost/low risk process and a low cost/high risk process. Final selection of the Bio-Denipho process was based on comparison of both processes in pilot tests. During the six months operation period the process control programs for weekdays/weekends, day hours/night hours, dry weather flows/storm weather flows resulted in low nitrogen concentrations in the effluent.

Eriophyoidea is a well-known mite taxon of economic importance. Due to their small size, elucidating many of their bio-ecological aspects becomes a challenge. These mites are obligatory plant feeders, with high host specificity and vagrant (free living) and non-vagrant (part or whole life cycle in a host) lifestyles. The mobility (distance walked - mm, resting time - s, and number of stops) of these mites on host and non-host plant species has been investigated. Eriophyoid species were submitted to walking tests on host and non-host plants using five vagrant species and five non-vagrant species. The walking was recorded with video tracking (ViewPoint) for ten minutes. Twenty replicates were performed for each treatment (eriophyoid species and plant). There was a difference in the behavioral response of the species studied in relation to the hosts. When the species were grouped by ecological lifestyle (vagrant and non-vagrant), non-vagrant eriophyoids presented a higher mobility (higher distance walked, less resting time) than vagrant eriophyoids on their respective hosts. There was no difference in the mobility of vagrant and non-vagrant species on non-host plants. The absence of a pattern of behavioral response among the species tested here indicates that more factors are involved in the host identification and acceptance process.

The elaboration presents conceptual and content aspects of an author’s model for educating ecological culture in introducing 5- to 6- year-old children into the natural world. The need for new interactive systems for environmental education in childhood is being defended. The vectors of pre-school ecological education and schooling are brought forth, they are addressed through the cognitive-information, personal, cultural and competence paradigms. The structure of the competence conceptual idea in pre-school ecological education is specified. In the context of the European educational priorities for early preparation and presentation of natural science competences, the basic principles that make up the model of “Molivko – I play and I know. Environmental studies” are brought out; it is designed to introduce 5- to 6-year-olds into the world of nature. They require cognitive and informational stimulation of personal experience in orientation in the natural world, empirically-active behavioural and communication regulation in the socio-environmental surroundings, model-situational systematization of ideas for maintaining a sustainable environment, reflexive-emotional attitude to the picture of the world of nature of the individual. Accordingly, the goal of the pedagogical interaction “child – nature”, which is referred to the initial stage of compulsory pre-school education, is set out. The integrative aspects of the author’s model related to game, socialization, knowledge, communication, safety, health, physical culture, labour and artistic creativity are set. The content accents of the model system, built up by adapting key concepts and skills related to bio-ecology, social and applied ecology, which in their unity guarantee the cognitive basis of the children’s ecological culture, are specified. Methodological ideas and solutions, laid down in the applied-educational provision of the author’s system are interpreted. Emphasis is placed on the inclusion of an accessible practice-transforming research activity, participation in modelling activities, children’s presentation and discussion with environmental content, collection, project activity. They are achieved through viewing, demonstration, multimedia presentations, talk, storytelling, reading of artistic works, didactic games, exercises, elementary experiments, modelling, staging, etudes, cases, etc. They are guaranteed by educational interaction, which presupposes the achievement of educational trends for key natural-science competences in the third age group, theoretically set and covered in applied-education field.

Tittle: Sustainability Analysis of Small Scale Fisheries in Tegal District of Central Java (a Fish Approach).The research on sustainability of small scale fisheries in Tegal district, Central Java has been carried out. Fishery sustainability is determined by several interacting factors, such as ecology, technology, social, economic and legal-institution. The objective of this study was to determine the sustainability status of small scale fishery according to ecological, technological, social, economic, and legal-institutional dimensions. The second objective was to identify policy promoting for the capture fisheries sustainability. Sustainability of fishery in the coastal area of Tegal district analyzed quantitatively by Rap fish technique. Fishing gears, such as Jaring Rampus, Bundes and Payang Gemplo weren’t in sustainable status from ecological, economic, technical and legal- institutional standpoints. The study showed that ecological aspect has the lowest score in order to support small scale fishery sustainability in the coastal water of Tegal. Differences in sustainability status are likely due to variations in main characteristic of the fisheries. Several sensitive attributes and recommendations in order to support fisheries sustainability, also identified in this study. This study reconfirms the need to apply comprehensive and integrated bio-technico-socioeconomic aspects in developing fisheries management.

The agriculture sector produces significant amounts of organic residues and the choice of the management strategy of these flows affects the environmental sustainability of the sector. The scientific literature is rich with innovative processes for the production of bio-based products (BBP) from agriculture residues, aimed at the implementation of circular economy principles. Based on literature data, the present paper performed a life cycle assessment and assessed the environmental sustainability of five processes for the exploitation of rice and wheat straw, tomato pomace, and orange peel. The analysis identified as significant issues the high energy demand and the use of high impact organic solvent. The comparison of BBP with conventional products showed higher environmental loads for the innovative processes that used organic residues (except for rice straw case). The obtained results do not want to discourage the circular strategy in the agriculture sector, but rather to draw the attention of all stakeholders to the environmental sustainability aspects, focusing on the necessity to decrease the electricity demand and identify ecological agents to use in BBP manufacturing, in agreement with the most recent European policies.

Abstract Arbuscular mycorrhiza fungi (AMF) play an essential role in various agroecosystems since they build symbiosis mutualism with plants. Understanding the differences in the distribution and diversity of AMF in cocoa plants with different elevations is important to explore the bio-ecological aspects of AMF. This study examined the differences in the number and types of AMF spores in cocoa plantations at three different elevations: <500, >500-1000, and >1000 masl. Environmental factors such as the physical and chemical properties of the soil were also investigated. This study found that the number of AMF spores was higher in the lowlands (<500 masl) than in the highlands. Rarefaction curves show that all soil samples taken are adequate for diversity analysis. Multivariate analysis with NMDS followed by the goodness of fit statistical test using the Bray Curtis method showed that a clear distribution pattern in the AMF community structure was significantly influenced by chemical and physical factors of the soil in the form of phosphorus, potassium, sodium, magnesium, total nitrogen, clay, and soil texture.

The global surge in environmental pollution, largely attributed to industrialization, has fueled a pressing need for sustainable solutions. In response, the construction sector is increasingly focusing on bio-based materials such as hemp, recognized for its low environmental footprint and prominent carbon-negative quality. As designers, housebuilders, and an environmentally conscious society pivot towards ecological alternatives to standard building materials, hempcrete emerges as a promising candidate. As a composite material mainly made from hemp hurd/shiv, water, and lime, hempcrete offers the ability to sequester carbon long after its incorporation into structures. As a result, the hemp cultivation process—which can be completed within less than four months—ensures that more carbon is absorbed during production and deployment than emitted, e.g., per one study, sequestration on the order of 300 kg of CO2 per m3 of hempcrete. In comparison to concrete, hempcrete offers a more sustainable footprint, given its recyclability post life cycle. This state-of-the-art review paper delves deep into different aspects of hempcrete, summarizing its multifaceted attributes, particularly its compressive strength. Based on the study conducted, the paper also suggests strategies to augment this strength, thereby transitioning hempcrete from a non-load-bearing material to one capable of shouldering significant weight. As architects and designers consistently strive to align their projects with high ecological standards, focusing not just on aesthetic appeal but also environmental compatibility, hempcrete becomes an increasingly fitting solution for the future of construction.

The article is devoted to one of the topical problems of modern science – the problem of correlating a person with his environment. This problem is considered by the scientific community from different angles, depending on the components of the environment. It is generally accepted that the ecological aspects of the study of this interaction lie in the field of biology, chemistry and physiology, and the social sciences remain outside the subject. Man, as a bio-psycho-social being, cannot but interact with the components of the social environment. The article substantiates the methodology for studying the state of the social environment, aimed at optimizing the socio-ecological interaction in the system “man – social environment”. This approach makes it possible to assess the factors of the social environment in terms of the human dimension. The study of the influence of factors of the social environment on the demographic behavior of a person is important for optimizing the socio-ecological interaction in the “man – social environment” system. The article discusses the conditions for the action of an organized personality in a favorable and unfavorable social environment, the direct and indirect influence of environmental factors on a person’s demographic attitudes. Social and intrapersonal interaction in a human-sized and non-human-sized social environment takes various forms and methods, since it depends on the conditions of the individual’s action, including norms and values in the immediate environment of society as a whole. Factors of the social environment that have both direct and indirect effects on the demographic behavior of a person can be used as criteria for assessing the human dimension of the social environment. In conclusion, it is said about the significance of the results obtained for the development of ways of greening the social environment and its harmonization in relation to a person.

The goal of these study was to present results of investigation concerning possibilities of utilization of harmful wastes in countryside area to produce ecological energy. Biogas production can be important from the point of view of environment protection especially in case of overproduction of animal wastes. Production and utilization of energy from agriculture residues gives a great chance for diversification and grows of income for family farms. Besides energetic and environment gains, we can obtain very valuable fertilizer, which is easy absorbed by plants in field crop production. The experimental study was conducted to investigate the effect of mixing process on the parameters of methane fermentation process. Temperature inside fermentation chamber, pH of fermented material, redox potential and carbon to nitrogen ratio (C:N) were investigated. Utilize wastes from pig and poultry houses were used for the study. Digestion in a chamber was provided at constant temperature of 37 °C. After adding fresh substrate to the digester, the temperature of the raw material decreased by 1,0-1.5 °C depending on the location in the tank. Also, it was observed that biogas production decreased. The mixing process had a positive effect on the homogeneity of the material throughout the digester volume. The best results for biogas production were obtained when the pH value was 7.0. Research results obtained from tested biogas installation show, that from two bio reactors at total capacity of 410 m3 we can get electrical energy at cost of 34,52 € MWh-1 and thermal energy at cost of 62,54 €×MWh-1. While the cost of producing electricity in a professional power plant based on lignite was 76.23 €MWh-1. The energy produced was used for the operational activities of the farm.

In freshwater and marine ecosystems, the phytoplankton community is based on microalgae and cyanobacteria, which include phylogenetically very diverse groups of oxygenic photoautotrophs. In the process of evolution, they developed a wide range of bio(geo)chemical adaptations that allow them to effectively use solar radiation, CO2, and nutrients, as well as major and trace elements, to form O2 and organic compounds with a high chemical bond energy. The inclusion of chemical elements in the key processes of energy and plastic metabolism in the cell is determined by redox conditions and the abundance and metabolic availability of elements in the paleoenvironment. Geochemical evolution, which proceeded simultaneously with the evolution of biosystems, contributed to an increase in the number of metals and trace elements acting as cofactors of enzymes involved in metabolism and maintaining homeostasis in the first photoautotrophs. The diversity of metal-containing enzymes and the adaptive ability to replace one element with another without losing the functional properties of enzymes ensured the high ecological plasticity of species and allowed microalgae and cyanobacteria to successfully colonize a wide variety of habitats. In this review, we consider the main aspects of the modern concepts of the biogeochemical evolution of aquatic ecosystems and the role of some metals in the main bioenergetic processes in photosynthetic prokaryotes and eukaryotes. We present generalized data on the efficiency of the assimilation of key nutrients by phytoplankton and their importance in the cycle of carbon, silicon, nitrogen, phosphorus, sulfur, and iron. This article presents modern views on the evolutionary prerequisites for the formation of elemental signatures in different systematic groups of microalgae, as well as the possibility of using the stoichiometric ratio in the study of biological and geochemical processes in aquatic ecosystems.

In this article, our intention is to provide an in-depth framework to inform the management of the inevitable complexity of day-to-day practice and supervision in child protection and welfare. It is based on what is now well evidenced about child protection and welfare literature in relation to risk, relationships, family support, supervision, and professional development. Using Ireland as a case example for illustration and application, we introduce an emerging framework based on a dualism of ‘protective support and supportive protection’ developed in previous work. We avail of Bronfenbrenner’s bio-ecological framework and network theories to progress this ongoing ‘work in progress’ to inform social work and social care practice and supervision in a global context as and where appropriate. We emphasize the importance of context specific approaches, the relevance of range of actors, practitioner and supervisor expertise through experience, and proactive partnership based engagement with children, families, and relevant communities in all aspects of service delivery, including evaluation. We reflect on the challenges and possible obstacles to how such a framework can inform practice and supervision. We argue that practitioners can best activate and apply the framework using a practice research approach.

The term "hydrocarbon" is self-explanatory and refers to solely carbon and hydrogen compounds. Hydrocarbons play an important role in our everyday lives. Hydrocarbons, particularly polycyclic aromatic hydrocarbons, harm biota. The relatively fast introduction of xenobiotic compounds, as well as the enormous movement of natural materials to various environmental compartments, can often overwhelm the self-cleaning capabilities of the recipient ecosystem, resulting in pollution and accumulation of hazardous or even lethal levels. Bacteria capable of hydrocarbon degradation are frequently used in the bioremediation of fuel oil-contaminated sites. Presently, multiple sophisticated methodologies, transcriptomics, proteomics and are effectively utilized for the depiction of hydrocarbons degrading microorganisms. These expertises are highly developed, and its integration with bioinformatics tools makes it even more efficient. Though health science and biological science are the major relevant areas for molecular docking, it has been effectively used to explore the process of bio-degradation in ecological remediation in recent years. This review focuses on the sources, fate of PAHs, human exposure, various computational aspects associated with PAHs, and some approaches of synthetic biology related to pollutant degradation and PAH‑degradation by genetically engineered microorganisms.

Nowadays, the Mediterranean is a hotspot of biodiversity, characterized by changes in fish communities due to invasions. These invasions, mainly occurring through the entrance of species through the Suez Canal, a process called Lessepsian migration, has been increasing in the last 40 years. It is reported that, in Turkish seas, where 512 fish species are found, are 75 Lessepsian species. However, knowledge about the impact of Lessepsian species on native species is insufficient. This study aims to determine the bio-ecological characteristics and food interactions of a native Pagellus erythrinus and non-native Nemipterus randalli distributed in the Gökova Bay.In the monthly sampling survey, carried out between January 2016 and December 2016, 1698 N. randalli and 945 P. erythrinus individuals were collected. Length, weight, age, sex distributions and ratios, length-age, weight-age, length-weight relationships, condition factors, stomach contents and reproduction periods were examined to determine the interaction between species. According to results, the life span of P. erythrinus is longer than N. randalli in the Gökova Bay. Nevertheless, N. randalli grows faster than P. erythrinus. Reproduction periods of both two species show similarities. Food competition between species is found to be significantly high. Results of condition factors exhibit that N. randalli shows an increased ability to exploit the available food sources. Pagellus erythrinus displays strategies such as: early maturation, short reproduction period, reproduction in the deeper waters and batch spawning, to compete with N. randalli. With the invasive characteristics of N. randalli established a successful population in the Gökova Bay.

The growing bioeconomy will require a greater supply of biomass in the future for both bioenergy and bio-based products. Today, many bioenergy cropping systems (BCS) are suboptimal due to either social-ecological threats or technical limitations. In addition, the competition for land between bioenergy-crop cultivation, food-crop cultivation, and biodiversity conservation is expected to increase as a result of both continuous world population growth and expected severe climate change effects. This study investigates how BCS can become more social-ecologically sustainable in future. It brings together expert opinions from the fields of agronomy, economics, meteorology, and geography. Potential solutions to the following five main requirements for a more holistically sustainable supply of biomass are summarized: (i) bioenergy-crop cultivation should provide a beneficial social-ecological contribution, such as an increase in both biodiversity and landscape aesthetics, (ii) bioenergy crops should be cultivated on marginal agricultural land so as not to compete with food-crop production, (iii) BCS need to be resilient in the face of projected severe climate change effects, (iv) BCS should foster rural development and support the vast number of small-scale family farmers, managing about 80% of agricultural land and natural resources globally, and (v) bioenergy-crop cultivation must be planned and implemented systematically, using holistic approaches. Further research activities and policy incentives should not only consider the economic potential of bioenergy-crop cultivation, but also aspects of biodiversity, soil fertility, and climate change adaptation specific to site conditions and the given social context. This will help to adapt existing agricultural systems in a changing world and foster the development of a more social-ecologically sustainable bioeconomy.

The ecological impacts of invasive alien plant species (IAPS) are well-documented, but a dearth of studies exist concerning its economic, livelihood, biotechnological, and health risk assessment perspectives. IAPS management is currently expanding to ecological indicator and biotechnological aspects. Hence, this study aimed to investigate the phytoremediation potential, biomedical, and bio-safety applications of X. strumarium growing in different abandoned habitats in Khyber Pakhtunkhwa, Pakistan. In this study, 45 plants and soil samples were gathered from 15 abandoned sites and analyzed for Pb, Cd, Cu, and Zn concentrations; bioaccumulation (BA); and translocation factor (TF). The assayed Pb and Cd concentration was higher and above threshold in both soil–plant samples. BAF was found higher in roots than intact plants despite having a significant accumulation of Cd, Pb, and Zn, which shows high metals tolerance of this IAPS. PCA-ordination explained a high cumulative variance (98.9%) and separated roads and densely populated sites with comparatively high metals concentration, indicating the pseudometallophyte nature of X. strumarium. Soil, sand, and plant biomass were shown to be the major determinants affecting the heavy metals concentration and its phytoremediation significantly, which may be due to the soil’s metalliferous nature in the study area. This IAPS exhibited strong translocation and hyperaccumulation capacity in different functional traits with comparatively high Pb, Cd, and Zn (≥1 TF) mobility and, hence, can effectively be used for Pb phytoextraction and phytostabilization of Cd, Cu, and Zn, respectively. Likewise, several other non-spontaneous IAPS growing on such abandoned habitats might be promising for developing a reasonable strategic framework for heavy metals mitigation and health risk implications in this region.
