Abstract:

Abstract Research into and diagnosis of environmental change prior to the introduction of bioindicator methods were linked primarily to apparatus. Drawing attention to the reactions of organisms sensitive to that change and using them in environmental quality control have opened new opportunities for development of a new scientific discipline, known in the literature as bioindication. Bioindication combines several scientific disciplines, including biology, broadly conceived geography, and chemistry. It thus combines in a comprehensible manner apparatus-derived measurements (chemical analysis results) and areas of bioindicator exposure (situation and distance from the emitter), translating these parameters into bioindicators' anatomical and morphological reactions. The development of bioindicator methods progresses rapidly, and - as is usually the case under such circumstances - it is difficult to ensure that they are transparent and that no chaos ensues. In view of the above, it seems necessary to embark on a discussion of these issues and consider compiling lists of most applicable indicator organisms for examination of particular environmental toxins in particular environments.

Abstract:

Bioindicator plants are species that have the capacity to linearly uptake some elements (metal and metalloids) from the growing substrate, thus reflecting their concentration in the soil. Many factors can influence the uptake of these elements by plants, among which is the simultaneous presence of several metals, a common situation in contaminated or natural soils. A novel approach that can be used to validate the bioindication ability of a species growing on a polymetallic substrate is the design of experiment (DoE) approach. The aim of the present study was to apply the DoE in full factorial mode to model the Cu, Cd, Pb, Zn, and Cr bioindication capacity of Polygonum aviculare, used as the model plant. The results showed that P. aviculare has the ability to bioindicate Cd and Cr with a linear uptake (from 0.35 to 6.66, and 0.1 to 3.4 mg kg−1, respectively) unaffected by the presence of other metals. Conversely, the uptake of Pb, Cu, and Zn is strongly influenced by the presence of all the studied metals, making their concentration in the plant shoot not proportional to that of the soil. In conclusion, these preliminary results confirmed that the DoE can be used to predict the bioindicator abilities of a plant for several elements at the same time and to evaluate the interactions that can be established between variables in the growing medium and in the plant itself. However, more studies including other plant species are needed to confirm the effectiveness of this method.

Abstract:

The “MGP analysis” created by Dr. J. Aoki in 1983 and the “100 oribatid species” system proposed by Aoki in 1995, both for using oribatid communities as bioindicators, are described herein and compared to some other bioindicator protocols. By using the term “naturalness”, Aoki proposed to explain human impact on a gradient of several environments ranging from urban boulevard trees to intact forests.Although using “naturalness” was a vague concept, the idea might reflect the process of plant succession and changes in oribatid assemblages associated with different seral stages. Therefore, the use of oribatid mites as bioindicators might also be based on succession of the oribatid fauna.

Abstract:

Water contamination is much more common than imagined, because it is practically impossible today to have an ecosystem that has not suffered directly or indirectly from humans. Studies with the aim of genotoxicity and mutagenesis use bioindicators as the basis of tests, the most used are from the Allium ssp family. When we mention cytogenetic damage, the intensity depends mainly on the degree of exposure, quantity, chemical nature and of the possible combinations between the contaminants, also influenced by the characteristics and conditions of the environment in which the organisms considered bioindicators are submitted. The present work has the objective of analyzing the cytotoxic, genotoxic and mutagenic effects induced by contaminating material that cause chromosomal alterations by means of mitotic index analysis using as bioindicator Allium sativum (garlic). The experiment was carried out at the Laboratory of Cytogenetics and Culture of Vegetable Tissues at the University of the State of Mato Grosso (UNEMAT) at the Alta Floresta Campus - MT. The soil was collected and stored separately using 200 grams of each sample with three treatments: surface, 20 cm and 40 cm deep, making a tea with 200 ml of distilled water and then measuring the pH. Using a direct method where the bioindicator is submitted directly to the tea solution, awaiting the emission of roots, and the indirect method, where the bioindicator is submitted first, the stimulation of root formation for 72 hours and then is submitted to contaminating solution. The plates readings to observe the interior of the cell using crushing techniques were performed in 24, 48 and 72 hours of experiment (indirect method) and 24 hours (direct method, also measuring the roots). With the results, we can state that the material used as pollutant (soil sample) has a cytotoxic and genotoxic potential in the bioindicator material, presenting high potential in the cell cycle induction, provoking various chromosomal aberrations.

Abstract:

In this article, the bioindicator properties of Taraxacum officinale, a common plant in urban areas, are studied. The existence of a correlation between the environment and the content of heavy metals in plants determines the use of plants as indicators of natural and anthropogenic landscapes. The existence of a relationship between the amount of heavy metals in the environment and plants determines their use as indicators of pollution of natural and anthropogenic landscapes. Plant organisms are recognized as adequate bioindicators of environmental quality. It is T. officinale that is suitable for identification and has adequate response to changes in environmental conditions. As a bioindicator, plants in urban and industrial areas are used for biomonitoring. In our scientific research, the use of T. officinale species as a bioindicator of atmospheric and soil pollution was investigated for the first time in the conditions of Uzbekistan. In order to determine the accumulation of some heavy metals in the observation areas, the correlation of climate, soil and plant indicators was determined using mathematical analysis methods.

Abstract The circulation of the contents of Cu, Cd, and As was traced in the system of Chondrostoma nasus – Pomphorhynchus laevis – Contracaecum sp. – water – sediments from the Danube River in the Kudelin biotope. New data on the content of the elements examined are presented. The concentrations of the three elements in the materials studied, which included tissues, organs, and parasites of common nase, and water and sediments from the Kudelin biotope, were higher than the limits set forth in Bulgarian and international legislative documents. The bioindicator role of the tissues, organs, and parasites examined was revealed, and the liver of common nase and Contracaecum sp. were good bioindicators for Cd content, while P. laevis was a good bioindicator for As content.

Abstract:

This article shows the genesis of legal regulations in the range of environmental bioindication in national legislation as a result of the implementation of EU solutions. The most important legal act in EU is the FrameworkWater Directive while the Water Law of 2017 in Poland. The main purposeof these legal acts is to maintain a good status, especially ecological status orpotential of water bodies based on bioindication. Changes in this area contributed to detailing and standardizing of the biological indicators of waters,which allow for a more detailed examination of the status of waters and defning the directions of their protection. The assessment of water quality inWarmian-Mazurian Voivodship indicates that approximately 30% of the lakes studied in 2010–2017, had at least good ecological status or potential. In70% of the lakes, primarily phytoplankton (the most sensitive bioindicator)decided on lowering to below good ecological status/potential. Recently, thefnal assessment of the status (ecological plus chemical) of water bodies hasbeen more rigorous due to chemical status based on exceeded content of priority substances in fsh (i.e. in another important bioindicator)

Abstract:

The usefulness of bioindicators to study the state of the environment in different compartments (air, water, and soil) has been demonstrated for a long time. All persistent pollutants can be measured in some form of bioindicator, and numerous organisms are suitable for the biomonitoring purpose. In most of the works on this topic, bioindicators are used to highlight the impact of human activities. Generally, samples collected from polluted areas are compared with samples from an area considered as clean, or samples from areas characterized by different pollution sources are compared with each other. An approach that has not been attempted consists in correlating directly data on environmental quality obtained by bioindicators with parameters measuring the population health. In the present study, the concentrations of As, Cd, Co, Cu, Fe, Mn, Ni, Pb, V, and Zn measured by atomic emission spectrometry (ICP OES) in 56 samples of holm oak bark from trees located in urban parks and along streets in a Northern Italy city were related to the data describing the health status of the citizens. The concentrations of some of the 10 trace elements in the bioindicator were found significantly correlated with mortality and morbidity data regarding cardiac and respiratory diseases. The results, although preliminary, show the potential of this approach for implementing strategies aimed for disease prevention and health promotion in urban areas at risk, with the objective of reducing environmental and health inequalities.

Abstract:

Abstract In Brazil, the expansion of agricultural activity and the associated indiscriminate use of herbicides such as glyphosate is directly related to the loss of biodiversity in the Cerrado. The identification of plant species as bioindicators of herbicide action, especially species native to the area, can help in monitoring the impacts of xenobiotics in the remaining Cerrado. Thus, this study was designed to evaluate the possible use of the native Cerrado species Pouteria torta as a bioindicator of glyphosate action via changes in physiological performance. At 16 months after sowing, the effect of glyphosate was evaluated by applying the following doses: 0 (control), 25, 50, 100, 200, 400, 800, and 1200 g a.e. ha-1. In response to glyphosate, P. torta exhibited reductions in photosynthesis and chloroplastid pigment content, as well as accumulation of shikimic acid and the occurrence of chlorosis and necrosis. These changes demonstrate the high sensitivity of P. torta to glyphosate and its potential for use as a bioindicator of this herbicide.

Abstract:

Bioindication of the environment is one of the actively developing directions of ecology. Information about pollutants and the level of environmental pollution can be obtained as a result of studying the biological reaction of plants to pollution. Ecological palynology is a new direction, when pollen of various woody and herbaceous species is used for bioindication of the level of environmental pollution and the presence of mutagens. The review considers the morphological variability of pollen, its fertility and viability under the influence of pollutants, the possibility of its use as a bioindicator of pollution of urban areas by emissions of vehicle transport and industry.

Abstract:

Pollution and other types of environmental stress do not spare marine environments, especially those affected by high industrial pressure. Fish, especially coastal species, are used for monitoring the marine environment because they are particularly efficient as bioindicators thanks to their ability to bioaccumulate and biomagnify along the trophic chain. The aim of this research is to evaluate the bioaccumulation and the indirect bioindication ability of the European Hake, Merluccius merluccius (Linnaeus, 1758), one of the most important commercial fish species of the Mediterranean Sea. Morphological and histological alterations of the main target organs, such as liver and gills, have been investigated and the results showed a steatosis in the hepatic tissue. The accumulation of heavy metals has been analyzed by inductively coupled plasma mass spectrometry and for several metals it was showed a different concentration in the two sexes. Moreover, the expression of metallothioneins 1 and Heat Shock Protein 70 has been assessed by immunohistochemistry and did not show high level of expression. We underline the importance of contamination evaluation in commercial fish species and the utilization of the ichthyofauna as bioindicator of environmental quality.

Abstract:

Ants have been considered as useful to bioindication due to their ecological characteristics. However, an important characteristic of a bioindicator group, there must be a consistent and repeatable response to an environmental disturbance. On this matter, divergent responses have been reported, even among closely related taxa. The aim of this work was to compare the diversity of ant communities from three temperate forests with different disturbance level and correlate their abundance, species richness and diversity with that found in other arthropod communities in the same forests. The results suggest that the site has an important influence on community ants and their values of richness, abundance and diversity are correlated to communities of spiders, beetles, grasshopers and true bugs, but not in all studied zones. The answers to environmental changes are not only by numerical ratios of abundance, richness or diversity, but also by indirect and causal ecological interactions. Finally the data seems to be indicating that the responds of ants to environmental disturbing are not necessarily reflected on other organism communities, in consequence the role of ants as bioindicator could be misleading

Abstract:

Freshwater ecosystems provide essential ecosystem services and support biodiversity; however, their water quality and biological communities are influenced by adjacent agricultural land use. Aquatic macroinvertebrates are commonly used as bioindicators of stream conditions in freshwater biomonitoring programs. Sorting benthic samples for molecular identification is a time-consuming process, and this study investigates the potential of ethanol-collected environmental DNA (eDNA) for metabarcoding macroinvertebrates, especially for common bioindicator groups. The objective of this study was to compare macroinvertebrate composition between paired bulk tissue and ethanol eDNA samples, as eDNA could provide a less time-consuming and non-destructive method of sampling macroinvertebrates. We collected benthic samples from streams in Ontario, Canada, and found that community composition varied greatly between sampling methods and that few taxa were shared between paired tissue and ethanol samples, suggesting that ethanol eDNA is not an acceptable substitute. It is unclear why we did not detect all the organisms that were preserved in the ethanol, or the origin of the DNA we did detect. Furthermore, we also detected no difference in community composition for bioindicator taxa due to surrounding land use or water chemistry, suggesting sites were similar in ecological condition.

Abstract:

Abstract. Among the various parameters monitored in river monitoring networks, bioindicators provide very informative data. Analysing time variations in bioindicator data is tricky for water managers because the data sets are often short, irregular, and non-normally distributed. It is then a challenging methodological issue for scientists, as it is in Saône basin (30 000 km2, France) where, between 1998 and 2010, among 812 IBGN (French macroinvertebrate bioindicator) monitoring stations, only 71 time series have got more than 10 data values and were studied here. Combining various analytical tools (three parametric and non-parametric statistical tests plus a graphical analysis), 45 IBGN time series were classified as stationary and 26 as non-stationary (only one of which showing a degradation). Series from sampling stations located within the same hydroecoregion showed similar trends, while river size classes seemed to be non-significant to explain temporal trends. So, from a methodological point of view, combining statistical tests and graphical analysis is a relevant option when striving to improve trend detection. Moreover, it was possible to propose a way to summarise series in order to analyse links between ecological river quality indicators and land use stressors.

Abstract:

Daphniidae (Crustacea, Anomopoda) have often been utilized in toxicological studies and environmental monitoring of aquatic systems for a number of reasons, such as their sensitivity to toxins and their ease of culture, and because they are such important members of the zooplankton in so many lakes. The extensive literature on the use of Daphnia as a bioindicator of environmental pollution with metal ions is critically reviewed. A summary of the data on the toxicity of metal ions in Daphnia is presented. These studies have lead to attempts to standardize the use of the bioindicator, as well as the monitoring of procedures. There have also been efforts to derive a relationship between toxicity data and the actual properties of toxins. Such a relationship would be beneficial for predicting the power of toxicity. To date, however, the efforts to establish this relationship have not been satisfactory. This compilation of metal toxicity data and the presentation of the attempts to establish such relationships was carried out in anticipation that it would be useful in future studies that might lead to a universal theory of the effect of metal ion toxicity on aquatic organisms.Key words: aquatic toxicology, bioindicators, Daphniidae, metal ion toxicity.

Abstract:

POTENTIAL OF BIVALVE AS BIOINDICATOR OF METAL POLLUTION IN THE COASTAL AREA. Bioaccumulation database using various species of marine bivalves is useful to determine which species are suitable as bioindicators in pollution monitoring. In general, metal bioaccumulation in bivalve varies in every location and influenced by the biokinetics of each species depending on the environmental condition. Increasing accumulation of one metal will enhance the accumulation of other metal in bivalve tissue. This needs to be taken into account in interpreting metal concentrations in bivalve. Oysters and mussels have the potential as bio-indicators of metals, especially Cu and Zn, while scallops are more potential as bioindicators of Cd and Zn. Meanwhile, clams has the potential as a bioindicators of Zn. Change in shape (malformation) of bivalve shells due to heavy metal accumulation also observed. The rough structure, attachment of minerals to the shell, and thickening of the shell layer are some forms of changes in bivalve shell morphology.

Abstract:

Zooplankton communities are useful bioindicators that can provide information on the changes occurring in marine ecosystems. Therefore, investigation of zooplankton communities in marine and coastal national parks is essential. However, the surveys of zooplankton communities using morphological identification require considerable time and labor. Metabarcoding is a practical alternative that can detect various taxa simultaneously. In this study, metabarcoding was newly applied along with the traditional morphological identification to establish a method for zooplankton community survey in the Marine and Coastal National Park areas of Korea. By comparing the results of these two identification methods, the strengths and limitations of metabarcoding were verified with the zooplankton communities appearing in these areas. The sensitive detection capability of metabarcoding enabled the identification of potential bioindicator taxa associated with external factors (e.g., water temperature, salinity, topography, and chlorophyll a concentration) in these national parks. We propose the use of metabarcoding for efficient surveys of mesozooplankton communities in the Marine and Coastal National Parks to establish monitoring of bioindicator taxa. It is also necessary to continuously search for taxa with high research value in these national parks using metabarcoding. Establishing an ongoing monitoring system that employs this approach can provide an effective tool for managing marine ecosystems in the Marine and Coastal National Parks.

Only 15% of the industries in Citarum Watershed, specifically in Bandung Regency, West Bandung Regency, Sumedang Regency, Bandung City and Cimahi City, are registered as PROPER industries. They must comply to indicators as set in the Minister of Environment and Forestry Decree No. 3 In 2014 concerning Industrial Performance Rank in Environmental Management, as a requirement to apply for PROPER. Wastewater treatment and management, referencing to Minister of Environment and Forestry Decree No. 5 In 2014 concerning Wastewater Effluent Standards, must be performed to be registered as PROPER industries. Conducting only physical-chemical parameter monitoring of wastewater is insufficient to determine the safety of wastewater discharged into the river, therefore additional toxicity tests involving bioindicator are required to determine acute toxicity characteristic of wastewater. The acute toxicity test quantifies LC50 value based on death response of bioindicators from certain dosage. Daphnia magna was used as bioindicator in the toxicity test and probit software for analysis. In 2015-2016, the number of industries that discharged wastewater exceeding the standard was found greater in non-PROPER industries than in PROPER industries. Based on the toxicity level, both PROPER and non-PROPER industries have toxic properties, however PROPER industries of 2015-2016 is more toxic with LC5096 value reaching 2.79%.

Bioindicator defined as organisms or group of organism reflect and inform the ecosystem circumstance; environmental, ecological and biodiversity status as well as. Main criteria of bioindicator are as follow: taxonomical and biological characters of these organisms well-knew, cosmopolitan organisms, they have a well-response to habitat alteration, and their responses are closed correlated to all communities or properties of stress factors. Termites showed responses to environmental change, especially in habitat alteration. Termites responded to habitat alteration on termites composition change and termites richness decrease. Furthermore, termite�s richness strong correlated with another taxon in their community. Biological and taxonomical termites are well-known. In addition, a standard survey of termites has been developed to explore termite�s richness in tropics ecosystems. This implication, termites can be applied as one of the indicator organisms or bioindicator, notably their relation in ecological indicator and biodiversity indicator.

Abstract:

In the town of Armizonskoye, Tyumen Region, Russia, industrial enterprises emit more than 230 tons of various pollutants into the air, and only about 50% of that total is retained. In this work the quality of atmospheric air in Armizonskoye was studied using the bioindication method. The objectives of the study were to identify the main pollutants in the air and to determine the most sensitive test functions of woody and herbaceous plants. The chemical method was used to determine the quantity and array of substances, emitted by some enterprises in different parts of the town. The bioindicators were common dandelion Taraxacum officinale Wigg, great plantain Plantago major L., warty birch Betula pendula Roth, and boxelder maple Aceraceae nequndo. The chemical analysis showed that the air is mainly polluted with iron oxide, manganese compounds, and suspended solids. The main sources of pollution are utility companies, Armizonagrostroy, and road maintenance companies. The most sensitive indicator among woody plants was boxelder maple, and among herbaceous plants, common dandelion. The bioindication method helped to map more and less polluted territories.

Abstract:

The lichenoindication method has been used for several decades to assess the level of environmental pollution. As a result of numerous field and laboratory studies, it has been proved that the main factor in the destruction of lichens in cities is air pollution in industrial centers. There is no doubt that the microclimate conditions (an increase in air dryness, a change in temperature, a decrease and increase in dew, a weakening of solar radiation) have a negative impact on the spread of lichens. One of the most important problems of environmental assessment of the environment is the selection of bioindicators and the assessment of tolerance. It is important to study the species composition of lichens in natural and anthropogenic ecosystems. As symbiotic organisms, lichens are of particular importance for lichenological research. Under favorable conditions, their annual growth is 1-8 mm. Lichens are deciduous, bushy grow faster than scale. The average age of deciduous and shrubby lichens is 30-80 years, some of them live up to 600 years. Lichens play an important role as a bioindicator of environmental pollution. In comparison with chemicophysical methods, the bioindication method has a number of advantages. It does not require expensive equipment and fixtures. The results are obtained by continuous observations without interfering with the processes of vital activity of the organism. The differentiating factor of species composition in urban conditions is environmental pollution.

Abstract:

With the increasing human population, the protection of water resources is becoming a critical issue. Wetlands are one of the most important water resources, helping assimilate pollutants. Hence, the ecosystem integrity of wetlands is important. Plant bioindicators with phytoremediation (physiologically removing pollutants from the ecosystem by plants) capacity can be very helpful in this regard. Based on the current literature, this study specifically aims to overview plant bioindicators with phytoremediation ability. A systemic literature review (SLR) method was used to find a detailed overview of the most relevant research. A total of 70 plants were identified as bioindicators. Out of all the indicator plants, Phragmites australis, Sorghum saccharatum, Lepidium sativum, Sinapis alba, Apium nodiflorum, Arundo donax, Bolboschoenus maritimus, Juncus acutus, Nasturtium officinale, Typha angustifolia and Typha domingensis was identified as the most studied bioindicator plants. The literature review revealed that these plant bioindicators had treatment impacts on metals, nutrients, urban runoffs and wastewater. According to studies, the roots of these plant bioindicators are primarily for absorbing pollutants, which is a specific physiological property of phytoremediation. Hence, the study concluded that for specific waste materials this set of plant bioindicators can be strong contenders for understanding wetland ecosystem integrity and their physiological mechanisms of phytoremediation can provide a blueprint for developing “bioindicators” for wetlands.

Abstract:

The use of fish species uses as bioindicators is an important environmental monitoring tool. Histological biomarkers are adopted to assess the health conditions of different organisms and to indicate an environmental hazard. Histology can be applied as an effective method to analyze the effects of pollutants and other stressors. Accordingly, histological changes in the gill epithelium were analyzed to assess the adoption of fish species Menticirrhus americanus (Linnaeus, 1758) and Micropogonias furnieri (Desmarest, 1823) as a bioindicator to measure environmental quality in Paraty and Sepetiba bays, in Rio de Janeiro. A random sample of 58 fish was collected from the assessed bays. We found Paraty Bay to be in good conservation condition, whereas Sepetiba Bay is contaminated. The fish species collected from Sepetiba Bay showed lesions such as epithelial lifting, aneurysm, and necrosis in the gills; thus, it was possible to suggest that histological biomarkers be used bioindicators to measure the environmental impact in these bays.

Abstract:

Crocodilians are considered as good indicators of ecosystem health since environmental conditions will influence them at individual (body condition and health parameters) and populational levels (population dynamics and behavior). Despite that, there are few attempts to use crocodilians as bioindicators and the lack of baseline health parameters is an impediment to this. Here, hematological and biochemical reference values for free-ranging Caiman latirostris (broad-snouted caiman) in the Brazilian Atlantic Forest, one of the most threatened biomes in the world, are proposed. Young caiman are more sensitive to environmental variations, besides being more abundant and more easily captured, when compared to adults, which facilitates their use as bioindicators. Furthermore, problems that affect young caimans may represent future population problems. The data obtained is an important tool in assessing the health of free-living populations, contributing to the use of C. latirostris as a bioindicator of health in the Atlantic Forest aquatic ecosystem.

Abstract:

Environmental quality assessment of the drainage basin of Lake Engure using Scots pine as a bioindicator Environmental quality assessment of the Lake Engure drainage area, which is the LT(S)ER region of the Latvian National Long-term Ecological Research network (Latvia LTER), was conducted using three bioindication methods based on Scots pine Pinus sylvestris L.: unspecific bioindication by pine needle tip necrosis, ground level ozone assessment by pine needle chlorotic mottling, and chemical analysis of pine bark. Samples were collected from 40 sites of the region in November 2010. Extent of needle tip necroses did not exceed class 4 (maximum possible value 6). The highest value of index of needle damage by ozone was Idam = 1.62 (maximum possible value 6). Multiple regression analysis of variables describing bark chemistry and needle damage in relation to distance from the sea, nearest roads and villages was performed. Pine bark acidity pH(KCl) and concentration of Mg and Fe decreased significantly (βpH(KCl) = -0.672, P < 0.001; βMg = -0.676, P < 0.001; βFe = -0.514, P < 0.001) with distance of sample site from gravel roads. Electric conductivity (EC) of pine bark and the extent of ozone damage of the first year needles Idam significantly decreased with distance from the sea (βozone = -0.507, P < 0.01; βEC = -0.453, P < 0.01). PCA of the pine bark chemistry data showed dust pollution from gravel roads to be the main factor responsible for the 33% variation of data. No statistically significant correlations were found between different bioindicator characteristics, except between first and second year ozone damage (ρ = 0.589, P = 0.01).

Abstract:

The article presents data on the study of the diversity of crustacean communities in the Moscow-river basin. Two most common are two species of amphipods, invasive species Gmelinodes fasciatus and the native species Gammarus lacustris, were detected and studies during the study. However, the number of one of the most important bioindicator species of crustaceans, Asellus aquaticus found in our samples is insufficient for quantitative conclusions. At the same time, population of G. fasciatus can be characterized as stable at all studied stations and the species can be used as bioindicator of the natural condition of the river flowing within the Moscow City. The species seems to be significantly less sensitive to environment conditions and especially anthropogenic pollution than the native amphipod species G. lacustris and can successfully replace A. aquaticus as bioindicator species in the area where the latter species is absent. Thus, a new bioindicator pair Gammarus lacustris / Gmelinoides fasciatus is suggested for using in estimation water pollution In European part of the Russian Federation and adjacent areas.

Abstract:

For a number of years “classical” programs for environmental monitoring are being supplemented by bioindication measures. Investigations on living organisms or their remains (e.g. peat) are used to indicate the environmental situation in either qualitative (bioindication) or quantitative (biomonitoring) terms. This provides pieces of information on environmental burdens of a region at a given point of time or on its changes with time (trend analysis). Classical bioindication often deals with observation and measurements of chemical noxae (both inorganic and organic ones) in well-defined bio-indicator plants or animals (including man). In terms of analytical procedures and results there are parallel developments between progresses in bioindication and innovation in analytical methods. After some 30 years of development in bioindication there are now the following newer lines for further development: 1) more frequent inclusion of multi-element total analyses for a thorough investigation of mutual correlations in the sense of the Biological System of Elements; 2) more work on (analytical) speciation issues to proceed into real effect-oriented environmental sciences; and 3) there should and must be a focus on integrative bioindication methods because for a large number of environmental monitoring problems a single bioindicator will not provide any meaningful information: a single bioindicator is about as good as none at all. Integrative concepts such as the Multi-Markered Bioindication Concept (MMBC) provide basic means to get into precautionary environmental protection effects drawing upon such a second-generation bioindication methodology. The selected case studies in Lithuania illiustrate some new aspects for the development of integrative bioindication consept. Santrauka Jau keletą metų „klasikinės“ aplinkos stebėjimo programos yra papildomos bioindikacinėmis priemonėmis. Atliekami gyvųjų organizmų arba jų liekanų (pvz., durpių) tyrimai, siekiant nustatyti aplinkos būklę kokybiniu (bioindikacija) arba kiekybiniu (biostebėsena) požiūriu. Taip gáunama informacijos apie regiono aplinkos problemas tam tikru metu arba aplinkos pokyčius laikui bėgant (tendencijų analizė). Taikant klasikinę bioindikaciją dažnai stebimos ir organinės, ir neorganinės cheminės medžiagos, matuojamos jų koncentracijos tiksliai nustatytuose bioindikatoriniuose augaluose arba gyvūnuose (taip pat ir žmogaus organizme). Kalbant apie analizines procedūras ir rezultatus, pastebimos panašios bioindikatorių tobulinimo ir naujų analizinių metodų plėtojimo tendencijos. Bioindikacijos plėtrai vykstant jau beveik 30 metų, išskirtinos tam tìkros tolesnės plėtotės tendencijos: 1) atliekant išsamius elementų biologinės sistemos tarpusavio sąsajų tyrimus dažniau pasirenkama kelių elementų bendroji analizė; 2) daugiau dirbama (analizinis darbas) sprendžiant naujų rūšių atsiradimo klausimus siekiant pereiti prie aplinkos mokslų, nukreiptų į tikrąjį poveikį; 3) daugiau dėmesio skiriama kompleksiniams bioindikaciniams metodams, nes esant daugybei aplinkos stebėsenos problemų, pavienis bioindikatorius daug vertingos informacijos neteikia. Kompleksinės koncepcijos, pavyzdžiui, daugiaženklės bioindikacijos koncepcija, remdamosi antrosios kartos bioindikacijos metodika, numato paprastų aplinkos apsaugos prevencijos priemonių.

Abstract:

The monitoring evaluation of anthropogenic transformation level of the environment was made according to viability of pollen Malus domestica Borkh. and Prunus cerasus L. The research was conducted in 2015-2017. The monitoring areas were located on the territories of preschool- and general educational institutions of Chernivtsi city. The pollen of the plants, which grow in locations of the background territory (landscape wildlife preserve Tsetsyno), was used as a control. As the result of the research, it was found out that the increase of anthropogenic loading level caused the productivity rise of sterile pollen grain. It was also discovered that M. domestica has a higher sensitivity than P. cerasus due to its capacity to produce fertile pollen with mean concentration of starch as a response to the atmospheric pollution. The mentioned feature of M. domestica expands the opportunities of its use as a bioindicator and also can indicate the anthropogenic transformation of environment. According to the integral conditional index of bioindicator’s damage, it was assessed that a satisfactory state of environment is on the Nebesnoi Sotni 18-A st., F. Poletaeva3 st., Saltykova-Shedrina29 st., Ruska178 st. and Nebesnoi Sotni 10-B st., when an ecological situation in other monitoring areas corresponds to the standards of cleanness. The main reason for the increase of pollen sterility of the bioindicators on the above-listed streets is a close proximity to the highways with an active traffic and traffic congestion.

Honeybees interact strongly with vegetables, air, soil, and water in the vicinity of the hive and, as a consequence, pollutants from these sources are translated to the honeybees and to the hive products. Therefore, over the last decades of the past century, honeybees and honey have been proposed as possible bioindicators for the study of the environmental status of the area surrounding the hive. This work is a critical review on the use of the hive as a passive sampling device and on the use of honeybees and honey as environmental bioindicator substrates for metals and radionuclides. The design of sampling networks, sampling procedures, sample pretreatments, analytical techniques, data analysis, and other influencing factors in this area are also reviewed.

Abstract:

The determination of the condition of river water quality is critical to establishing sustainable water resource management policies. The use of bioindicators tests for the evaluation of water quality is a valuable tool, and the nematode C. elegans is described as a good organism to assess toxicological risks in aquatic and soil environments. The samples of water were collected in three stretches of the Paranhana and Ilha rivers (P1, P2 and P3) in November (spring) of 2018, January (summer) of 2019, April (autumn) of 2019, and August (winter) of 2019. The physic-chemical parameters were analyzed according to the standard methods (Standard Methods for the examination of Water and Wastewater 23rd edition). The nematode strains used are savage lineage N2 and were obtained through the Caenorhabidits Genetics Center (CGC) for the bioindicator test. The development evaluation was verified by the body surface area measurement of 20 nematodes which were quantified thru the ImageJ software. Most of the physic-chemical parameters were within the limits recommended by CONAMA, but aluminum, that presented values ten times higher than the recommended limit. Significant differences were observed in the nematodes development from all the samples when compared to the control group (p<0,001). The analysis of nematode development demonstrated that the bioindicator was sensitive to the research, showing that ecotoxicological assays are important for a more realistic scenario of threats to water quality, and C. elegans allows this assessment to be performed adequately.

Abstract:

The contamination of heavy metals in the aquatic environment poses a threat due to its persistence and potential accumulation in aquatic life forms. In order to detect such pollution, the use of organisms as bioindicators was explored. This study investigated the use of fish acanthocephalan parasites as bioindicator of lead (Pb) in a semi-pristine Yambo Lake in San Pablo, Laguna, Philippines. Lake water samples, wild Nile tilapias (Oreochromis niloticus), its acanthocephalan parasites (Acanthogyrus sp.), and Asian clams (Corbicula fluminea) were collected and subjected to Pb concentration detection through heavy metal analysis. Higher accumulated mean concentration levels of Pb is recorded in Acanthogyrus sp. (10.13 mg kg-1), followed by the fish host tissues: liver (6.19 mg kg-1), intestine (2.80 mg kg-1), and muscle (0.75 mg kg-1). An established bioindicator, C. fluminea, only accumulated an average of 0.16 mg kg-1 Pb in its soft tissues. The bioaccumulation capacity of Acanthogyrus sp. to the fish host and water samples were 35 times higher than the liver, 190 times the intestine and 211 times than the muscle. Furthermore, the accumulated Pb in the parasite was 3,015 times higher than C. fluminea in lake water. Among all samples analyzed, Acanthogyrus sp. showed the highest accumulation capacity. These findings provide useful information to the bio indicator potential of this parasite, and that local environment authorities can utilize its sensitivity to detect and monitor traces of heavy metals even in less polluted aquatic environments.

Abstract:

Drosophila Fallen, 1823 (Diptera, Drosophilidae) is for long a well-established model organism for genetics and evolutionary research. The ecology of these flies, however, has only recently been better studied. Recent papers show that Drosophila assemblies can be used as bioindicators of forested environment degradation. In this work the bioindicator potential of drosophilids was evaluated in a naturally opened environment, a coastal strand-forest (restinga). Data from nine consecutive seasonal collections revealed strong temporal fluctuation pattern of the majority of Drosophila species groups. Drosophila willistoni group was more abundant at autumns, whereas D. cardini and D. tripunctata groups were, respectively, expressive at winters and springs, and D. repleta group at both seasons. The exotic species D. simulans Sturtevant, 1919 (from D. melanogaster group) and Zaprionus indianus Gupta, 1970 were most abundant at summers. Overall, the assemblage structure did not show the same characteristics of forested or urban environments, but was similar to the forests at winters and to cities at summers. This raises the question that this locality may already been under urbanization impact. Also, this can be interpreted as an easily invaded site for exotic species, what might lead to biotic homogenization and therefore can put in check the usage of drosophilid assemblages as bioindicators at open environments.

The return to pasture use as an alternative to intensive livestock farming implies some risks with the lack or the excessive presence of potentially toxic elements; in this regard, wild animals have been used as bioindicators for decades. Thus, the purpose of this study is quantifying Cu, Cr, Mn, Zn, Se, As, Cd, Ni, Pb, Al, Fe, and Mg in fur from roe deer and understanding if it is a valid bioindicator tool. Hair was collected from 39 hunted roe deer and divided by age (<36 months old/≥36 months old), sex (male/female), and area of origin (urbanized/rural area). The mean concentrations of Fe, Mg, Mn, Al, Cr, and Pb were higher (p < 0.05) in the urbanized group; the mean levels of Mg and Cr were higher (p < 0.05) in older animals; and Cu, Fe, Mg, Cd, and Cr showed a higher accumulation in females. Our findings showed an age-related variation of elements, with higher concentrations in adult animals and females. In conclusion, our findings prove that hair is a valid matrix for this type of survey, and wild animals are good bioindicators for monitoring the presence of trace elements in pastures.

ABSTRACT Information about the impact of herbicides in the soil based on the growth of bioindicator species is extremely useful in developing crop management strategies. Therefore, this study aims to evaluate the leaching potential of the herbicide S-metolachlor under different natural precipitations in medium-textured Oxisol using bioindicator plants. A completely randomized experimental design was adopted, with four replicates and treatments arranged in a 3 × 8 factorial scheme [three indexes of precipitation occurred in the environment before the collection of the samples (50, 91, and 131 mm) and eight depths in the soil profile (0-0.03; 0.03-0.06; 0.06-0.09; 0.09-0.12; 0.12-0.15; 0.15-0.20; 0.20-0.25; 0.25-0.30 m)]. PVC columns were used, maintaining the original soil integrity during sampling after accumulating the stipulated natural precipitation. Longitudinal sections separated the columns to sow the bioindicator species (cucumber, lettuce, Alexander grass, and sorghum). The phytotoxicity symptoms of bioindicator plants were evaluated, adopting a phytotoxicity visual scale between 0 and 100%, at 5, 7, 9, and 11 days after seeding. The responses of the bioindicator species to the residual effect of the herbicide S-metolachlor were variable and depended on the rainfall level. Generally, in a medium-textured Oxisol, the higher values of concentration of S-metolachlor occurs in depths ranging between 0 and 0.06 m. The maximum leaching depth detected was 0.12-0.15 m with 131 mm of precipitation. Cucumber was the most sensitive species to the presence of S-metolachlor in an Oxisol of medium-texture since it presents symptoms of phytotoxicity at higher depths.

We found that marine bacterium Vibrio harveyi may be an appropriate bioindicator of mutagenic pollution. For positive selection of mutants, we developed a simple method for isolation of V. harveyimutants resistant to neomycin. We constructed genetically modifiedV. harveyi strains that produce significantly more neomycin-resistant mutants upon treatment with low concentrations of mutagens than the wild-type counterpart. The sensitivity of the mutagenicity test with the V. harveyi strains is at least comparable to (if not higher than) that of the commonly used Ames test, which uses Salmonella enterica serovar Typhimurium strains. Therefore, we consider that the V. harveyi strains described in this report could be used as potential bioindicators of mutagenic pollution of marine environments.

Abstract:

The results of studies of chemical pollution (Pb, Zn) of perennial grasses—Elymus repens L., Artemisia absinthium L., and Hypericum perforatum L.—on background plots and within the areas of impact of industrial enterprises in Kropyvnytskyi (Ukraine) are presented. It is noted that chemical pollution is the most dangerous. The activity of enterprises is considered, in the result of which heavy metals enter the air. Testing of plants (stems and leaves) was carried out at a distance of 10–100 m from the enterprises. The content of heavy metals in the aboveground part of plants was analysed by atomic absorption spectrophotometer in the laboratory of the Department of Exploratory and Ecological Geochemistry, IGMR NAS of Ukraine. The comparison of sorption properties of different plants in the same phases of development allowed plants with bioindication capabilities to be identified. The results of the analysis showed that plants most effectively accumulate the maximum amount of heavy metals from the atmospheric air at the end of the summer dormancy phase (second half of August). At this time the plant requires the minimum amount of nutrients that it takes from the soil. Stems and leaves of perennial grasses actively accumulate aerosols and fine dust on their surface due to plant secretions with the formation of a mucous film that actively adsorbs heavy metal ions. The background, minimum, and maximum content of heavy metals in plants is determined. Comparing the content of heavy metals in plant samples in the background and study plots, it was found that E. repens near industrial enterprises is the most effective bioindicator of air pollution. In order to determine the level of atmospheric air pollution using bioindication methods, the index of plant contamination (Sр) was proposed, which is the ratio of concentration coefficient of heavy metals and their amount. An assessment scale for atmospheric air pollution with heavy metals has been developed based on the contamination index (Sр) of bioindicator plants: the degree of pollution is 1–3—weak, 3–6—medium, 6–9—strong, more than 9—very strong. The proposed coefficients allow for conducting a situational assessment of atmospheric air pollution with heavy metals using bioindication methods.

Abstract:

Insects are part of the forest ecosystem that plays an important role in the sustainability of the ecological functions of the forest plantations. The purpose of this study was to analyze the effect of thinning on insect communities and determine the types of insects which has potential to be bioindicators in order to assess the success of thinning in forest plantations. This research was conducted on forest plantation at the part of Forest Management Unit (BKPH) Cikawung and West Gede, Forest Management Resort (RPH) Ciguha, Forest Management Unit (KPH) Sukabumi Perum Perhutani Regional Division III West Java and Banten. The plot used in this research is a circular plot with a radius of 17.95 m. The traps used are malaise traps that is spread on thinning blocks at thinning intensity of 20%. The type of stand of thinning plots is Pinus merkusii in the age class 3. The obtained insects later identified to the morphospecies level. The results of the study show that thinning affect changes in environmental conditions and insect composition. In thinning blocks, there was decrease in the number of insect compositions by 11 families, 4 genera and also decrease of 3 morphospecies. Overall, thinning activities have no effect on changes over species richness index and evenness index of insect species. Diptera is a type of insect that can be used as a bioindicator, it states based on the consideration of ease in obtaining information related to taxonomy and biological properties, ease of identification, role of the ecosystem, pressure status and abundance parameters.

Buchori D, Rizali A, Rahayu GA, Mansur I. 2018. Insect diversity in post-mining areas: Investigating their potential role as bioindicator of reclamation success. Biodiversitas 19: 1696-1702. Reclamation can be a pivotal process to return an ecosystem to its condition prior to human disturbance, by recreating a landscape so that its structure and function closely resemble a natural community. Unfortunately, there is a lack of empirical data as to whether reclamation efforts successfully establish sustainable of the ecosystem or not. The objective of this research was to study insect diversity in post-mining areas and investigate their potential role as bioindicators of reclamation success. An ecological research was conducted in post-mining reclamation areas managed by PT. Berau Coal in Binungan, East Kalimantan. We selected sub-areas that had been subject to reclamation efforts for varying periods, ranging from 2 to 10 years, for observation. We also used an area of undisturbed natural forest as a comparison. Inside each of these subareas of different reclamation age, insects were sampled using pitfall traps and malaise traps along a 100-meter transect. Our results showed that insect diversity differed in areas of different reclamation age. Based on CCA revealed that environmental factors i.e. pioneer tree age, vegetation diversity and soil chemistry (N total) affected the diversity of insects in the reclamation area. In particular, NMDS analysis showed different species composition in ant communities found in subareas of varying reclamation age. We conclude that ants are the most useful potential bioindicator to assess reclamation success in post-mining areas.

Abstract:

There is a resurgence to measure or monitor the impact of intensive exploitation of natural resources on environment and original habitats. The indicator qualities of terrestrial invertebrates are widely recognized in the context of detecting ecological change associated with human land-use. However, the use of terrestrial invertebrates as bioindicators remains more a topic of scientific discourse than a part of land-management practice, largely because their inordinate numbers, taxonomic challenges and general unfamiliarity make invertebrates too intimidating for most land-management agencies. Terrestrial invertebrates will not be widely adopted as bioindicators in land management until simple and efficient protocols have been developed that meet the needs of land managers. There are several characteristics that an indicator species must have, the most notable being ease of measurement, sensitivity to environmental stress, and predictable responses to environmental stress. Ants are increasingly being recognized as useful tools as bioindicators for land managers to monitor ecosystem health conditions. This group has useful characteristics for successful indication and monitoring of environmental impacts, including widespread distribution, high abundance, importance in ecosystem functioning, ease of sampling, and latively well-known taxonomy and ecology. With this back ground, we aimed to conduct review of literature study with the main purpose to describe and delineate on current perspectives on use of ants as bioindicators.
