Abstract:

It is important to build a scientific and effective indicator system for the assessment and management of regional ecological construction. A theme-based and network coupled framework provides a useful approach to solve some problems in establishing indicator systems, such as lack of systematic study on indicators connotation and non-transparent processes of indicators selection. Based on the ecological construction practice in Fujian province, China, this paper (1) analyzed the main challenges of the ecological construction,implementation and development processes, summarized the currently main themes for ecological construction, and built a theme-based indicators framework; (2) established indicators selection criteria matrix and alternative indicators matrix by using network analysis method; (3) built a multi-objective selection model considering the economic cost, social effect and ecological integrity by genetic algorithm to quantitatively select operational indicators of ecological construction. Our study will contribute to deeply understanding the connotation and improving the science and validity of the ecological indicators system for ecological construction assessment and management applications.

Abstract:

Indicators can monitor ecological environment changes and help maintain ecological balance. Bioindicators are divided into animal, plant, and microbial indicators, of which animal and plant indicators have previously been the most researched, but microbial indicators have drawn attention recently owing to their high sensitivity to the environment and their potential for use in monitoring environmental changes. To date, reviews of studies of animals and plants as indicator species have frequently been conducted, but reviews of research on microorganisms as indicator species have been rare. In this review, we summarize and analyze studies using microorganisms as indicator species in a variety of ecosystems, such as forests, deserts, aquatic and plateau ecosystems, and artificial ecosystems, which are contained in wetlands, farmlands, and mining ecosystems. This review provides useful information for the further use of microorganisms as indicators to reflect the changes in different environmental ecosystems.

Abstract:

- The use of socio-economic indicators in the analysis of health outcomes is not straightforward because those conditions act in a mediated and indirect way through the adoption of life styles, the characteristics of job or the capabilities of utilizing the opportunity of wellbeing offered by the modern health systems. Validity analyses of the national deprivation index based on indicators derived from national Census are summarized. Spatial and temporal stability of the association between deprivation and mortality are reviewed and Italian examples presented. Mutual standardization bias and ecological fallacy when using census tract data are also illustrated with original data based on longitudinal census cohorts studies. Keywords: material deprivation, mortality, validity, ecological fallacy, epidemiology, ecological bias. Parole chiave: deprivazione materiale, mortalitÀ, validazione, distorsione ecologica, epidemiologia, bias ecologico.

Abstract:

The high functional and unmatched biological diversity represented by arthropods demand that these organisms be considered as ecological indicators of sustainable forest management. Successful use of arthropods in this capacity will require a systematic and rigorous process, including selection of potential indicators, definition of relationships between indicators and disturbance variables, optimization of the useful range of the indicator and application of the indicator(s) in monitoring. In Canada, the single greatest impediment to the use of arthropods as ecological indicators is the importance of accurate species-level identification and the difficulty achieving it. Consequently, most work has focused on a few relatively well-known groups (e.g., epigaeic carabid and staphylinid beetles and spiders, saproxylic beetles, butterflies and larger night flying moths).Many recent studies have provided baseline data about the range of natural variation and have begun to quantify arthropod responses to natural and anthropogenic disturbances in the context of preplanned experiments or through various retrospective approaches. Carabid beetles are the best-studied group and sufficient sets of data now exist to permit a meta-analysis of the robustness of carabids as indicators across multiple spatial scales and in terms of how well they represent broader ecological responses to disturbances. There is good potential to incorporate arthropod indicators into monitoring programs in Canada, but it is necessary to first complete a scientifically credible selection process for specific ecological indicators. Future research should focus on completing the process for taxa under current study as this develops the best presently understood opportunities for using arthropod indicators in assessing various aspects of environmental change. Researchers should also consider other means of monitoring arthropod biodiversity by the use of surrogate ecological parameters such as ecological land classification and habitat classification systems. Key words: arthropods, ecological indicators, monitoring, biodiversity, taxonomy, sustainability

Abstract:

The aim of this research is to build an ecological early warning indicator system. Several complex and interlinked factors contribute to changes in the environmental quality of scenic areas. If changes in these factors can be monitored and controlled, the environmental quality of scenic areas can also be controlled, achieving the purpose of protecting the ecological environment. This study utilizes ecological early warning indicators to enable environmental management. Twenty-six early warning indicators are first identified through a literature review, interviews, and survey pretesting. A fuzzy analytic hierarchy process is then used to calculate the weights of different levels/hierarchies. These early warning indicators can be used both to assess the environmental quality of scenic areas, and to provide a foundation for the construction of an ecological early warning indicator system in scenic areas. This approach represents a new perspective on scenic area environmental management and ecological protection.

Abstract:

The environmental threats and risks assessment is carried out on the basis of various anthropogenic criteria analysis. It’s reasonable to assess certain environmental indicators for each type of technogenic danger. The problems of the maximum permissible environmental load assessment and the development of the regional environmental security assessment methods have been actual. Therefore, the aim of the article is to develop the basics of the regional environment security level assessment methodology. It’s expedient to assess certain partial environmental indicators for each type of technogenic hazard. Such partial indicators were analyzed by statistical methods. The integration method was used to develop partial and integral indicators for assessing the regional environmental security level. The result of the research is proposition to assess the regional environmental security level by two groups of environmental factors: 1) antropogenic substances ingress into the environment and 2) natural systems change, caused by natural resources consumption and spatial planning factors. Application of the regional environmental security assessment methodology will allow to formalize environmental management problems by using the following indicators: integral environmental security indicator of reducing the anthropogenic substances ingress into the environments (II1) and integral environmental security indicator of reducing natural system change, caused by natural resources consumption and spatial planning factors (II2).

Abstract:

Traditional automatic control systems do not solve the task of limiting the harmful effects of technical objects on the environment. The problem is to increase the effectiveness of means of its protection against the harmful effects of industry. Relevant is the use of indicators of environmental performance of technical objects as controlled parameters. A new approach to the control of technical objects is proposed. As the main control parameter it proposed to adopt the level of their ecological efficiency. Complicating circumstances of solving the problem is the insufficient knowledge of the factors of harmful effects on objects of living nature, their intensity, interrelation, mechanism, strength, and dynamics of exposure. Improving the economic efficiency of technical objects leads to an increase in their ecological efficiency. The solution to the problem is facilitated by the fact that traditional ACS should be left in action, adding to them an ecological efficiency control component. Heat-powerengineering has a large impact on the environment through emissions and discharges of harmful substances and heat. To give to ASC the functions of controlling the ecological efficiency of the boiler (for SOy emission), it is necessary to apply an additional, new control loop - regulator of SOy concentration in furnace gases. An urgent task in the use of direct control of the ecological efficiency of boiler-furnace systems is the development and production of physical quantity sensors, reflecting the level of aggressiveness of the source of hazard, working in real time. Direct control of indicators of ecological efficiency is much easier in other branches of industry, in particular, in its food branch, where objects do not have a large-scale complex negative impact on the environment.

Abstract:

Urban land consolidation, which reforms land parcels to remove fragmentation and produce ideal blocks, is an effective means of urban renewal. Successful urban land consolidation benefits city officials as well as the general public, in improved city image, increased land value, and more effective land use. However, urban land consolidation can be ecologically detrimental to the environment, while land consolidation has focused solely on development for human benefit. To remove the negative effects of urban land consolidation on the ecological system, this paper establishes a set of criteria for evaluating ecological impacts of an urban land consolidation plan. The current study first identifies key ecological indicators using a special group decision‐making process called “habitual domain analysis” and then records individual weighting of each indicator by an analytical hierarchy process, thus developing an urban ecological evaluation model with four levels and twenty‐three indicators.

Abstract:

Indicators are being sought for monitoring the ecological integrity of forests and other kinds of ecosystems. Biological measures are commonly used as indicators because of their inherent ecological importance and ability to provide insight into environmental change. Such measures are commonly based on data from sets of permanent plots in which the abundances of plant species are monitored. However, the data may be difficult to interpret, especially if corresponding information on natural and anthropogenic stressors is lacking. In this review, we examine general principles of indicator use and discuss the types of plot-based compositional measures obtained from vegetation that may be most relevant for monitoring ecological integrity. Our focus is on the ground vegetation of forested ecosystems, but the principles discussed are relevant to other vegetation types. Individual plant species, guilds, aliens, diversity indices, Ellenberg indicator values, the floristic quality assessment index, multivariate and multimetric indicators are examined, as well as concepts of threshold changes and the need for reference states. The usefulness of any given approach tends to be highly context specific. In particular, the value of using individual species as indicators is highly dependant on factors such as the character of the floristic community of interest and the types and intensities of anthropogenic stressors. Alien species are considered to be especially valuable indicators of changes in ecological integrity due to their established relationships with anthropogenic stressors, known historical state, relevance to all floristic communities, and ability to cause undesirable changes to biodiversity and ecological processes.

Abstract:

Using the most popular measures of inequality and recent statistical data, the authors estimate interregional inequalities in Russia. The specific aim of this study is to identify inequality in well-being indicators, which were calculated using a multiplicative model based on the A. Sen extended function. It includes GRP per capita, share of personal incomes in GRP, cost of living index in the region, intra-regional income inequality and the integrated environmental index (it is defined as the arithmetic mean of the environmental indices calculated on the basis of the indicators: share of the negative water, air and soil tests). Using a multiplicative model, we evaluate the following social welfare indicators for Russian regions: indicator S (without the environmental component E); indicator SE (the environmental component E is defined as average of specific indices that take into account the air and water bodies state); indicator SEs (the environmental component E is defined as average of specific indices that take into account the air, water bodies and soil state). Our calculations have revealed that there is a significant interregional differentiation in the social well-being level. The environmentally adjusted well-being exhibits higher levels of inequality than the indicator that does not take into account the environmental component. The paper shows that from 2008 to 2019 the gaps between Russian regions had in some cases increased.

Abstract:

The aim of the research is to present the development of scientifically-methodological foundations of the irrigated lands and water bodies’ ecological state’s assessment with the prospects for their improvement on the base of remote sensing data usage. The development of evaluation of ecological state in the article highlights the stages of formation and improvement. The unified integrated approach to the assessment of the hydrogeological, engineering-geological and soil-reclamation conditions and prediction of their changes under the influence of irrigation is the result of the formation stage. At the stage of theoretical justification and development of the scientific foundations of ecological reclamation monitoring, a methodology for the spatial assessment of the ecological reclamation state of irrigated lands was developed for the assessment of their resistance to the harmful effects of water and soils degradation. Taking into account ecological aspects the definition of ecologically-ameliorative state was applied. An ecologically-ameliorative stability of lands - complex indicator of the geosystem’ state’s dynamic is proposed . The ecologically-ameliorative stability is proposed to consider as potential (genetic) and as actual (technogenic). A comparison of the potential and actual ecologically-ameliorative stability of lands for different periods of time, taking into account the level of anthropogenic pressure on the territory, makes possible to predict the ecological state of the lands under irrigation. The current general tendency to reduce the volume of monitoring work, long-term stationary research, the size of the observation network, and the actual areas of controlled lands leads to the decreasing of the results’ information fulfillment. At the modern stage, the theoretically-methodological foundations for the determination and practical application of estimated indicators of the reclaimed land and water bodies’ state based on remote sensing data have been developed.Were organized the polygons for the results aprobation. The software “Database of spectral signatures” was developed to collect and store the results processing of the satellite information. The software AnalistNOAA was developed to analyze the hydrothermal conditions of Ukraine. The program “Multi-criteria assessment of irrigation territories” makes it possible to coordinate individual chemical and physical indicators. To achieve the optimal level of ordering of terrestrial and satellite information, a theory of their interchangeability has been developed on the whole. Conclusions. The assessment methodology is based on the concept of ecologically-ameliorative stability of lands. It allows a comprehensive spatial assessment and forecasting of the ecologically-ameliorative state of irrigated farmlands. The use of remote sensing data is an effective mean to increase the level of information and responsiveness of ground-based research in the spatial assessment of the ecological state, water-ecological and ecologically-ameliorative situations. Improvement of the scientifically-methodological foundations for assessing the ecological state of reclaimed land and water bodies is based on the obtaining of the temporal (year, month, week) and spatial (region, district, economy, field) values based on a variety of satellite information and partial or complete replacement of the estimated indicators determined by the ground surveys, by the remote sensing data determined indicators.

Abstract:

The objective of this article is to apply an ecological indicator screening method, which is the Comprehensive Method for Water Ecological Index Screening (CMWEIS). CMWEIS is based on the Principal Component Analysis (PCA) and the Delphi Method (DM, a kind of expert investigation method). Not only the objective factors but also the subjective factors are considered. Using CMWEIS, the ecological indicators were sorted in the range of Liao River basin. 25 ecological indexes, 2 years’ observed data of the main stream of Liao River were considered. Ten specialists were invited to answer the designed questionnaires. After 5 times of screening, the score of each ecological index was provided and 11 indexes were selected. CMWEIS considered both the objective characters of the indicators and the subjective adjustment of the specialists. So the indexes selected by WEIDSM could reflect the ecological status well and truly. The model was programmed and all the statistical calculations were done by the computer. It could be expected that WEIDSM could give the sequence of ecological indicators quickly, so as to make ecological monitoring or evaluating more effectively.

Abstract:

The article presents the results of the seaport ecological condition indicators study of a depressed industrial hub. The traditional ranking of indicators of ecological condition on three levels is analyzed: international, national, regional. Based on the recommendations of Eco Port PERS, the requirements of ISO 14001 and environmental management and audit, EMAS analyzes the environmental indicators that are recommended for use. The scientific novelty is the justification of the necessity to use the territorial indicator of the seaport ecological condition due to the specifics of the territorial location - first, the nature of the seaport as a city-forming enterprise - secondly, the seaport - the third, deterioration of an ecological situation of an industrial site, in - the fourth. The ecological model of the seaport is based on its division into two subsystems: production and consumer, and the link between them is transport and transport processes. The necessity of maintaining the ecological and economic balance in the seaport and on the territory of the depressed industrial hub is substantiated according to the indicators of the cargo transportation intensity, the quality of transport services and the current ecological situation of the territory as a whole, which is provided by the System of ecological condition of European ports PERS.

Abstract:

The work examines modern methodological approaches to assessing the quality of life using environmental indicators. Analysis of the existing methods in Ukraine for determining the environmental component when measuring the quality of life showed the need to develop a new method for a comprehensive assessment of the state of the environment. This is due to the fact that the existing methodology for assessing the quality of life does not take into account the ecological component as a separate block of indicators, and also contains some inaccuracies in the formulas for calculating the final indicator. In this regard, a new method is proposed for determining the ecological component in the general system for assessing the quality of life of the population, which is the scientific novelty of the work. Based on the analysis of monitoring data on the quality of air, surface waters and soils of Ukraine, statistical reporting on environmental indicators of the development of regions of Ukraine, intermediate indicator indicators are calculated, and then the final complex indicator of the state of the environment is determined. Calculation formulas and assessment scales in points of the state of environmental components are proposed. The proposed method is based on the processing of data from official state statistics and environmental monitoring, which determines the reliability of the initial data. The proposed technique can easily be used as an algorithm for computerized calculations of the indicator of a comprehensive assessment of the state of the environment. The calculation of the indicator of the ecological state was made on the basis of current statistical data, which showed the need for immediate environmental protection measures in the industrially developed regions of Ukraine: Donetsk, Zaporozhye, Dnepropetrovsk and Lugansk regions.

Abstract:

Orchid bees have been considered as good ecological indicators of habitat disturbances but recently Añino et al. (2019. Sociobiology, 66: 194-197) highlighted reasons why Euglossini role as indicators should be reevaluated. Despite agreeing with some points raised by them, we present an alternative view for the use of orchid bees as indicators. For us, the main problematic issues are: (i) the authors do not present a clear definition of ecological indicator, including its role as an indirect measure of biota response to disturbed environments; (ii) they do not properly acknowledge the relative good taxonomic status of orchid bees when compared with the remaining bees; (iii) and they do not distinguish the use of particular Euglossini species as indicators in certain circumstances. In spite of some knowledge gaps, we argue that Euglossini is a good candidate to be ecological indicators in tropical forests, maybe the best candidate among all the bees.

Abstract:

The implementation of ecological restoration programs is intensively changing the original ecological carrying capacity and the status of ecological security. To evaluate the spatiotemporal variation of ecological carrying capacity and ecological security in China’s eco-engineering areas, an indicator system of ecological carrying capacity and ecological security should be developed. This study developed an evaluation indicator system that contains 29 indicators. The indicators were generated by long-time series and multi-source data. The indicator system presents the relationship between ecological carrying capacity and ecological security and reflects the dynamic change of them in eco-engineering areas. We selected the Three-River Headwaters Region (TRHR) and implemented the Ecological Conservation and Construction Program (ECCP) as a case study. The results showed the variation of ecological carrying capacity (ECC) and ecological security (ES) in the TRHR before (2000–2004), during early term (2005–2009), and during medium term (2010–2015) implementation of ECCP, and limiting factors of ecological carrying capacity and ecological security in TRHR was analyzed. The results showed that the ECC index and the ES index were significantly increase, indicating that the ECC improved and that the ES state got better in the TRHR after implementing ECCP. The water conservation was the major factors limiting the increase of the ECC. The leading factors limiting the improvement of the ES were educational expenditure before 2010 and turned into proportion of tertiary industry and investments for ecological restoration after 2010. The implementation of the ECCP has improved the ES state but has also resulted in new problems. It provides a scientific reference for future research on the indicator system of ecological carrying capacity and ecological security in eco-engineering areas and also has vital practical significance to guide the sustainable development of ecological restoration programs.

Abstract:

Abstract Successful implementation of Ecosystem-Based Fisheries Management (EBFM) requires appropriate action as informed by reference points in an ecosystem context. Thresholds in the response of ecological indicators to system drivers have been suggested as reference points for EBFM, though the management performance of these indicators and possible values for their reference points have not been widely evaluated. We used Management Strategy Evaluation to test the performance of control rules that used ecological indicators to adjust the advice from single-species stock assessments, using the Georges Bank finfish fishery as a case study. We compare the performance of control rules that used ecological indicators to that of single-species FMSY control rules when the system dynamics were governed by the same multispecies population model. Control rules that used indicator-based reference points were able to perform better against catch and biodiversity objectives than when harvests were based on single-species advice alone. Indicators and values for reference points associated with good performance varied depending on the management objective. We quantified tradeoffs between total catch, biodiversity, and interannual variability in catch, noting that it was possible in some instances to achieve higher than average biodiversity while maintaining high catches using indicator-based control rules. While improved performance was noted using ecological indicators, outcomes were variable, and the gains in performance obtained may be similar to alternative methods of implementing precaution in single-species fishery control rules.

Abstract:

In recent years, there has been an aggravation of problems in the field of environmental safety of surface water sources, which is caused by the unsatisfactory state of water resources. Among the reasons for this should be noted the lack of effective mechanisms for water management, control and responsibility. A comprehensive assessment of the environmental safety indicators of surface water sources of supply by chemical indicators is a laborious task. Indicators are obtained by combining and summarizing many complex indicators into one integrating one, which makes it possible to characterize different positions of water bodies. The practice of monitoring in surface water indicates the need to minimize resources to obtain a comprehensive assessment of the environmental safety of a water object. Therefore, the purpose of this work is to justify the choice as an indicative indicator of the ecological state of the surface source of drinking water supply of biochemical oxygen consumption. To do this, it is necessary to characterize the ecological state of the studied area using the combinatorial index of water pollution and establish a link between this index and biochemical oxygen consumption. The calculation of the value of the combinatorial pollution index and the relative assessment of the ecological state of surface water were carried out in two stages: first, for each individual investigated substance and indicator of the ecological state of surface water, then the entire complex of pollutants was considered simultaneously and the resulting assessment was derived. Baseline indicators play an important role in the ecology of a water object. Therefore, the content of dissolved oxygen and biochemical oxygen consumption in water is of great interest not only in terms of the development of life, but also as an indicative indicator of the ecological state of the aquatic environment, makes the indicator of biochemical oxygen consumption important for indicative assessment of water pollution by various organic substances. For the tasks for which we justify the choice of indicative indicators of the ecological state of surface water, it is more important to identify the consequences of pollution not directly at the site of pollution, but at some distance from it and after a while. Therefore, the use of the amount of dissolved oxygen and biochemical oxygen consumption as indicators characterizing the oxidation process of existing pollutants in water is the most appropriate for the tasks of operational monitoring of water bodies.

Abstract:

Free living Nematodes communities used as bioindicators of soil health because their composition well correlates with, two critical ecological processes i.e. nitrogen cycling and decomposition in soil . Nematodes indices withstand statistical rigor better than abundances, proportions, or ratios of trophic groups. Nematodes indices respond to a variety of land-management practices, based largely on life history characteristics of families.

Abstract:

Rapid urbanization and intensification of human activities increases the risk of disturbance of ecological systems via multiple sources, with consequences for regional ecological security and health. Landscape ecological risk assessment (LERA) is an effective way to identify and allocate risk to resources. We used the north and south Qinling Mountain area as a case study to analyze the spatial heterogeneity of landscape ecological risk using a potential- connectedness-resilience three-dimensional (PCR 3D) framework based on an integrated and dynamic risk assessment concept from adaptive cycle theory. We explored factors driving the risks with a spatial model GeoDetector. The results show that the comprehensive landscape ecological risk was north–south polarized and dominated by low and moderate risk levels (90.13% of total risk) across the whole study area. The high-risk area was centered on the Weihe plain north of the Qinling Mountains (NQL), while low-risk areas accounted for 86.87% of the total area and were prevalent across the south of the study area. The areas with high potential and connectedness risks were centered in the Xi’an–Xianyang urban agglomeration and those with high-resilience risk were in the upper reaches of the Hanjiang River. The vast majority of the area to the south of the Qinling Mountains (SQL) is at low risk. In terms of driving forces, population density and vegetation coverage (NDVI) are the primary factors affecting landscape ecological risk. Our findings suggest that anthropogenic activity is the primary cause of landscape ecological risks in the study area and regional socioeconomic exploitation and environmental conservation need to be rebalanced to achieve sustainability for the social ecosystem. The PCR 3D LERA framework employed in this study can be used to inform landscape ecological health and security and to optimize socioeconomic progress at regional scales.

Abstract:

Much of the basic ecology of Ebolavirus remains unresolved despite accumulating disease outbreaks, viral strains and evidence of animal hosts. Because human Ebolavirus epidemics have been linked to contact with wild mammals other than bats, traits shared by species that have been infected by Ebolavirus and their phylogenetic distribution could suggest ecological mechanisms contributing to human Ebolavirus spillovers. We compiled data on Ebolavirus exposure in mammals and corresponding data on life-history traits, movement, and diet, and used boosted regression trees (BRT) to identify predictors of exposure and infection for 119 species (hereafter hosts). Mapping the phylogenetic distribution of presumptive Ebolavirus hosts reveals that they are scattered across several distinct mammal clades, but concentrated among Old World fruit bats, primates and artiodactyls. While sampling effort was the most important predictor, explaining nearly as much of the variation among hosts as traits, BRT models distinguished hosts from all other species with greater than 97% accuracy, and revealed probable Ebolavirus hosts as large-bodied, frugivorous, and with slow life histories. Provisionally, results suggest that some insectivorous bat genera, Old World monkeys and forest antelopes should receive priority in Ebolavirus survey efforts. This article is part of the theme issue ‘Dynamic and integrative approaches to understanding pathogen spillover’.
