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.

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 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.

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.

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.

With the aim of analyzing water quality and verify the presence of phyto-zooplanktonic bioindicators in the Cocó River estuary, monthly plankton collections were carried out between April/22 and April/23. In situ the parameters of water temperature and transparency, salinity, pH, dissolved oxygen (DO), and phosphate and ammonia contents were obtained. The phyto-zooplankton was collected with a specific net and, in the laboratory, analyzed using a trinocular microscope with an attached camera. The presence of Escherichia coli was also verified. The results showed water with transparency characteristic of mesotrophic water, while the phosphate and ammonia contents were similar to those of eutrophic waters. 13 phytoplankton species were identified, distributed in the Cyanophyceae, Bacillariophyceae and Chlorophyceae Classes. As bioindicator species of eutrophicated waters were identified: Cylindrospermopsis raciborskii, Nitzschia sp., Chroococcus sp., Oscillatoria spp. and Ulothrix sp. Species diversity and richness were low, with significant evenness. As for the zooplankton, 18 species were identified, distributed in the Classes Eurotatoria, Copepoda, Branchiopoda, Tubulinea and Ostracoda. As bioindicator species: Brachionus calyciflorus, Filinia longiseta, Moina sp., Hexarthra sp. and Polyarthra sp. Diversity was medium, richness was low and evenness was significant. Microbiological analyzes showed the presence of E. coli. Overall, the waters of the Cocó River estuary were classified as Class 3 brackish and eutrophic.

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.

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.

This research aims to develop a standardised protocol for monitoring the disinfection efficacy of healthcare laundry processes in view of numerous differential methodologies currently being employed within the healthcare laundry sector, including agitation and surface sampling for post-laundering decontamination assessment and swatch and bioindicator testing for in-wash-process efficacy. Enterococcus faecium as an indicator species within industrial wash systems is preferable due to its high thermal and disinfectant tolerance. Methods for measuring laundry disinfection were compared; commercially available E. faecium bioindicators and contaminated cotton swatches (loose, in cloth bags or within nylon membranes) were laundered industrially at ambient temperature and microbial recovery determined. E. faecium was lost from cotton during laundering but retained by the bioindicator membrane, which allows disinfection efficacy to be measured without loss of microorganisms from the test swatch. Commercially available bioindicators were only permeable to disinfectants and detergents at ≥60 °C. Subsequently, polyethersulphone membranes for enclosing contaminated swatches were developed for low-temperature laundering, with permeability to industrial laundry chemistries at below ≤60 °C. This study demonstrates that bioindicators are the recommended methodology for laundry disinfection validation. The use of a universal healthcare laundry disinfection methodology will lead to standardised microbiological testing across the industry and improvements in infection control.

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 The bioindication methods have been implemented for the first time for the analyses of water properties in six mineral and thermal springs of Pamir. The studied environment was characterized as flow-alkaline, well oxygenated with low salinity, and low to middle organically polluted. Studied diatom communities preferred periphytonic and benthic habitats of temperate temperature waters. Bioindicator species preferred photosynthetic way of protein synthesis. In first time assessed the trophic level of each studied source show that all they have a state from oligotrophic to mesotrophic. Bioindication methods revealed the effectiveness of nature conservation system in Tajikistan and relevance of bioindication methods using in purpose of assessment and monitoring of water sources on the protected territories.

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.

Volatilization represents an important process in the displacement of pesticides for the environment. The physicochemical properties of the clomazone molecule indicate its relative volatility. Therefore, this study was carried out to assess the volatilization of different clomazone herbicide formulations using bioindicator species. To that end, airtight glass boxes were used with the presence of different clomazone formulations and plant species. The formulations used were Gamit 360 CS(r), Gamit 500 EC(r) and Gamit Star(r). The plant species assessed were maize, sorghum and rice. With the results obtained it is possible to conclude that, among the formulations, Gamit 360 CS(r) has caused less phytotoxicity to the bioindicator species in comparison to the formulations of Gamit 500 EC(r) and Gamit Star(r) formulations. In general, The Gamit 500 EC(r) and Gamit Star(r) have not differed in the phytotoxicity potential for the bioindicator species.

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.

Plankton are organisms that live floating in water bodies and move with the current. Plankton is a clue organism that can be used as a bioindicator because it is sensitive to environmental changes. The purpose of this study was to explore the limnological aspects of plankton distribution and diversity as bioindicators of water quality. In this study, 29 species of phytoplankton and 20 species of zooplankton were obtained, dominated by Nitzschia sp. and Asplanchna sp. The abundance index showed that the abundance of phytoplankton was 19386.67 ind/L and zooplankton was 5.33 ind/L. Water status based on phytoplankton diversity index with a value of 0.28-1.00 is categorized as low diversity and zooplankton diversity with a value of 0.78-1.97 is categorized as moderate diversity.

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 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.

The development of coastal zones throughout the world has resulted in changes in the order of the mangrove ecosystem, therefore, planting activities are carried out in various regions. The study of the testing and determination of gastropod species as bioindicators in the mangrove reforestation area was carried out in the Seribu Islands. This research aims to determine how suitable the gastropod species are used as bioindicators in assessing the success of mangrove reforestation, especially in the Seribu Islands. Collection of gastropod species is done by making line transects and plots drawn from the reference point (outermost mangrove stands) and perpendicular to the coastline to the mainland. Line transects are made of plots of size 10 x 10 m and in the size of 10 x 10 m a small plot of 1 x 1 m is made. Furthermore, testing is carried out with several criteria and analyzed using multivariate Principal Component Analysis (PCA) statistics. The results of the study show that the species Littoraria scabra has met all the specified testing criteria. Then L. scabra also has the highest eigenvalue compared to the other species, making it suitable to be used as a bioindicator species in assessing the success of the Seribu Islands mangrove reforestation.

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

Background & objectives: Sandflies are vector insects associated with terrestrial forest ecosystems; in the Ecuadorian Andes, they participate in the transmission of human cutaneous leishmaniasis. This geographical area represents an opportunity to evaluate the role of sandflies as bioindicators of the degree of intervention of tropical humid forest ecosystems (THF) associated with changes in the ecology of the local landscape. Methods: CDC-light traps were used for collecting adult sandflies in February 2020 in a humid tropical forest within the Chocó Biosphere Reserve. All species were identified using morphological keys. Analysis data about abundance, richness, species accumulation, diversity index, species composition communities, species sex proportion, spatial sandflies environmental, Renyi’s Diversity Profile were performed to compare six spatial habitats in Mashpi locality, Ecuador. Results: Sandflies were collected (n-1435); the main species are represented by Trichophoromyia reburra, Nyssomyia trapidoi, Psathyromyia aclydifera, Psychodopygus panamensis and Lutzomyia hartmanni. Only Th. reburra is associated with not intervened forest, while the other three species are associated with intervened forest within Mashpi in the Choco Biosphere Reserve. The secondary forest has major sandflies’ richness, while the primary forest exhibits major abundance. Interpretation & conclusion: Th. reburra is a sandfly restricted to the Andean Forest and is a bioindicator of the high environmental health quality of the forest, while Ny. trapidoi and Pa. aclydifera are bioindicators of environmental disturbances in the forest. Additionally, Ps. panamensis, Lu. hartmanni and Ny. trapidoi are bioindicators of human impact and the risk of leishmaniasis.

Dung beetles (Genus: Onthophagus) are members of the family Scarabaeidae and the subfamily Scarabaeinae. Despite their small size and unattractive appearance, dung beetles play an important role in the ecosystem, and they are widely recognised as one of the most effective bioindicators of ecosystem health. Although there has been an increase in dung beetle studies in Peninsular Malaysia, there are very few ecological studies of dung beetles conducted in Sarawak, despite being the largest state of Malaysia. Therefore, this study aims to provide recent information on the distributions of dung beetles from the genus Onthophagus in Sarawak. A total of 32 occurrences data for eight selected Onthophagus species representing 11 localities were successfully recorded. All analyses were performed using the Maximum Entropy Modelling Version 3.4.4 (MaxEnt) and Quantum Geographic Information Systems 3.28.2 (QGIS) software. It is revealed that most dung beetles’ distributions are strongly influenced by temperature and precipitation which suggests its capabilities as a bioindicator to identify high biodiversity areas. In conclusion, this study could be beneficial to identify the potential hotspot areas for biodiversity conservation and effective management practices in Sarawak.

Some authors have identified the Lontra longicaudis as an indicator of environmental quality, either due to its presence or absence in aquatic environments, being associated with the availability of prey and water quality. In order to address the issue at hand, this study examines the utilization of calculating the distribution of the intensity of the species' presence, in conjunction with emergy calculations and energy transformation in biodiversity and ecological compartments of the Caconde UHE system, to monitor the well-being of ecosystems. The findings demonstrate a consistent pattern of interannual and monthly presence of the otter in relation to the system. Lontra longicaudis, as a bioindicator for monitoring environmental health, becomes even more efficient if it is integrated into the analysis of emergy and transformity, allowing the quantification of energetic convergence between ecosystem processes and products. The utilization of bioindicator species located at the top of the trophic chain, such as lontra neotropical, holds significant importance in establishing restoration strategies for ecosystems.

Biomonitoring has been seen as complementary analysis to physicochemical methods and as a low-cost alternative, mainly for regions lacking air pollution control programs. Despite being the most widely used bioindicator for this type of pollution, lichens are not easily identified and this methodology is restricted to groups of expert researchers. Accordingly, the aim of the present study was to analyze lichen diversity in urban and industrial areas, in order to elaborate a dichotomous key to identify the listed species, based on easily visualized features. Lichens with leaf stalks belonging to family Parmeliaceae and genus Parmotrema were the most abundant, which are known for their resistance to air pollution. The study sites generally presented low lichen diversity, which may also have been influenced by the degree of vegetation around them. This result reinforces the importance of green areas for mitigating air pollution in urban environment. The dichotomous key elaborated for the lichen species found aims to support research, environmental education and management activities, and may expand the use of lichens as air-quality bioindicators.

AbstractThe phytosociology of lichens colonizing granitic churches and dolmens in Galicia (N.W. Spain) and Alentejo (central Portugal) was studied so as to identify (a) a group of species whose frequency on these structures would make them potentially useful as test species for the evaluation of biocides used for conservation, (b) environmental factors likely to control species distribution, and (c) species that may be useful as bioindicators of environmental factors in this kind of construction in the region studied. Chief among the factors correlating with species distribution is the class of structure (church or dolmen), which is attributed to the probable influence of this factor on environmental parameters affected by structural complexity, the presence of non-granitic materials and the influence of man in the immediate surroundings. The bioindicator species most sensitive to this complex of parameters appear to be three species found only on churches (Caloplaca citrina, Sarcogyne davits and Verrucaria macrostoma) and the most widespread of the species found only on dolmens (Lasallia pustulata). Other important factors, probably affecting the influence of class of structure, are pH and the availability of nitrogen and moisture.

Bioindicator species are used to assess the damage and magnitude of possible impacts of anthropic origin on the environment, such as the reckless consumption of antimicrobials. Chelonia mydas has several characteristics that make it a suitable bioindicator of marine pollution and of the presence of pathogens that cause diseases in humans. This study aimed to investigate the green sea turtle as a reservoir of resistant bacteria, mainly because C. mydas is the most frequent sea turtle species in Brazilian coastal regions and, consequently, under the intense impact of anthropic factors. Free-living green sea turtles ranging from 42.8 to 92 cm (average = 60.7 cm) were captured from Itaipú Beach, Brazil. Cloaca samples (characterizing the gastrointestinal tract) and neck samples (representing the transient microbiota) were collected. Bacterial species were identified, and their was resistance associated with the antimicrobials cephalothin, ciprofloxacin, gentamicin, tetracycline, and vancomycin. Citrobacter braaki, Klebsiella oxytoca, K. variicola and Proteus mirabilis were found resistant to cephalothin and Morganella morganii and Enterococcus faecalis tetracycline-resistant isolates in cloaca samples. In neck samples, species resistant to tetracycline were Salmonella sp., Serratia marcescens, S. ureylitica and Proteus mirabilis. This data reinforces that the green turtle is a bioindicator of antimicrobial resistance (AMR).

Charophyte algae is a very sensitive group of organisms occupying Kazakhstan waterbodies. They are distributed throughout the country; however, not enough studies have been conducted, especially in the southern region. Research carried out in 2019–2022 identified 33 habitats of charophyte algae in the south and southeastern regions of Kazakhstan, including 15 new to Kazakhstan. Bioindicators and the statistical analysis of 223 species of nine phyla of microalgae associated with charophytes revealed that the main factors influencing the distribution of algal diversity may be habitat altitude and hydrology. The habitat altitude of about 700 m above sea level was shown to be the boundary between the different diversity distributions. The application of bioindicator methods can expand our knowledge on the ecology of the charophyte species in Kazakhstan. The study of algal diversity in charophyte habitats can serve as a tool for tracking climate change under potential future climate warming.

Determining minimum water flows that will continuously run through a natural channel downstream of a water intake (Q0) is a multidisciplinary problem. It is, however, not approached in a multidisciplinary way in most countries. This paper offers an overview of the main methods and proposes a practical and environmentally more acceptable way of determining the retained flow, namely the environmentally acceptable flow (EAF). It is proposed that until the conditions are created for use of more complex methods and/or biological response techniques, the EAF be defined by determining whether the retained flow is sufficient for sustaining and developing indigenous wildlife in the streams by ensuring of the essential living conditions for the bioindicator species. The proposed bioindicators are characteristic fish populations of a specific type of stream and stream reaches. Being the final link in the ecological food chain, fish species are reliable indicators of bioecological balance in a stream.

Coastal waters of the Special Economic Zone (SEZ) Mandalika must be given more attention as it is the centre of tourism activities, including the International GP motor circuit on the island of Lombok. One of the bioindicators used in determining water quality is phytoplankton. Phytoplankton is tiny organisms that float on the water, have very weak swimming abilities, and their movements are heavily influenced by water flow. This research aimed to determine the diversity of phytoplankton as a bioindicator in the waters of Tanjung Aan, Central Lombok. Sampling sites in Tanjung Aan were determined by purposive sampling. This research was conducted from March to June 2023. The research results showed that there were six classes, 56 families, and 56 genera with 128 species in the community of phytoplankton. Species 113 were members of the class Bacillariophyceae. The phytoplankton abundance in three sampling sites ranged from 488 ind/L to 1109 ind/L. The species diversity indexes of phytoplankton in the three sampling sites ranged from 2.4 to 2.9, which means that the diversity is in the low category, and the species dominance index ranges from 0.12 to 0.15. This indicates that the condition of the waters of Tanjung Aan is slightly polluted.

Short Communication: Ant (Hymenoptera: Formicidae) diversity as bioindicator of agroecosystem health in northern slope of Mount Slamet, Central Java, Indonesia. Biodiversitas 18: 1475-1480. This study examined the diversity of ant assemblages in two different agroecosystems (organic and intensive farming) with maize as main crops on the northern slope of Mount Slamet, Indonesia from April to August 2015. The response of ant diversity to the different farming systems was evaluated. In total, 359 ants from 17 species in five subfamilies were collected: 13 species from the organic farm and 10 species from the conventional farm. Seven (41%) species were found only on the organic farm, four (23%) species were found only on the conventional farm, and six (35%) species were found on both. The Morisita-Horn similarity index (33%) showed that the similarity of the species composition in the two habitats was low. More individual ants were found on the organic farm than the intensive farm [287 (79.94%) vs. 72 (20.05%) individuals]. The diversity of the ants was affected by the density of weeds with organic farming. Hypoponera sp. had the highest Indicator Value (50.7), followed by Aphaenogaster sp. (28.9), Diacamma sp. (28.2), and Odontoponera sp. (27.6), however only Odontoponera sp can be used as bioindicator. Although the ant diversity was higher with organic farming than with intensive farming, there was no correlation with soil conditions. As a bioindicator, the Indicator Value reflects agroecosystem health better than does ant diversity.

Surakarta is a city with polluted air due to transportation activities. Utilization of bioindicators could be one of efforts to monitor air pollution. Lichen is one of the air quality bioindicators that can be observed based on its morphological characteristics. This study aimed to determine air quality using lichen bioindicators at two stations in the Jebres sub-district, namely on UNS street and Juanda street. These two locations have different environmental characteristics and traffic density. This study is a descriptive exploratory research using purposive sampling method. The collected data were analyzed qualitatively based on the morphological characteristics of the lichen found. The results showed that nine species of lichen found in UNS street area, while five species of lichen in Juanda street area. Apparently, morphological character of lichen consisted of crustose, leprose, and foliose thallus types with bright thallus colour, larger diameter, and more individuals, whereas in Juanda street is crustose and leprosy with a duller color, smaller diameter, and fewer individuals. In fact, the vehicle density in the area of Juanda street was higher than UNS street area. As it is largerly known that the type and morphology are influenced by the environmental quality. Therefore, based on the founded lichen’s type and morphology, the area of Juanda street was likely more polluted than UNS street area. Our finding suported that lichen could be bioindicator for air quality.

Water mites (Acariformes: Hydrachnidia) are one of the planet's most diverse and abundant groups of aquatic arthropods. With more than 7,500 described species, water mites have been documented in nearly every known freshwater environment. In lotic systems, water mites are commonly found in fast-flowing, riffle-run stream habitats, where one square meter of substrate can contain as many as 5,000 individual mites representing more than 50 species, 30 genera, and all 8 superfamilies. Despite their widespread distribution, relative diversity, and abundance, water mites have been widely neglected in freshwater biomonitoring efforts. However, several studies across the globe have found that water mites can be used as successful bioindicators of water quality conditions. Thus, the following study provides one of the first detailed examinations of lotic water mites and their bioindicator potential in North America. We sampled water mites from sites along 'attaining' (unpolluted) and agriculturally 'impaired' (polluted) riffle-run stream habitats and compared their assemblages to other physicochemical and benthic macroinvertebrate metrics used to quantify water quality in Pennsylvania. In total, we collected 9,139 individual water mites representing 5 superfamilies, 9 families, and 14 genera from both attaining (n = 13) and impaired (n = 13) streams. Similar to other global studies, we found significant differences between the water mite assemblages of attaining and impaired streams, with attaining streams having greater richness and diversity of water mites. Our data shows that several mite taxa are associated with biological and physicochemical conditions of water quality, where some known sensitive taxa are increasingly dominant in attaining streams and less dominant in impaired streams. Conversely, some pollution-tolerant taxa dominance increases in impaired streams while sensitive taxa abundance declines. These findings illustrate that water mites vary in their sensitivity to pollution and are suitable bioindicator species whose inclusion in biomonitoring assessments will increase assessment accuracy.

Three centipede species (Clinopodes flavidus, Cryptops anomalans and Eupolybothrus transsylvanicus) were used as bioindicators of trace metal and metalloid pollution in Belgrade, Serbia. The concentrations of 13 elements (the metals Mn, Co, Ni, Cu, Zn, Rb, Sr, Cd, Tl, Pb and U and metalloids As, Se) in whole animals and soil were measured by inductively coupled plasma mass spectrometry (ICP-MS). Differences in the concentrations of some elements in the analyzed species were observed, both in response to the sites and between species. In most cases, the trace element concentrations were higher in centipedes from a polluted site (an industrial area near a busy street with heavy traffic) but C. anomalans and E. transsylvanicus had higher Mn concentrations at an unpolluted site (a deciduous woodland on Mt. Avala). C. flavidus was a good bioindicator for detecting differences between Zn, Se and Cd. C. flavidus and C. anomalans were more efficient in accumulating Zn than E. transsylvanicus. It appears that C. anomalans poorly accumulated Cd, unlike C. flavidus and E. transsylvanicus, which accumulated Cd according to the high bioaccumulation factor (BAF) values. We conclude that the centipedes C. flavidus, C. anomalans and E. transsylvanicus can be used as suitable bioindicators of trace element exposure. Their ability to accumulate trace elements was different and depends on their physiology and lifestyle as well as the route of exposure.

This study aimed to determine the presence of metal elements in fruits and leaves of three tree species as bioindicators in San Luis Potosi, Mexico. Ninety fruit and 90 leaf samples (30 per tree species) were collected at five sites (agricultural, suburban, commercial and services, urban, and mining), using the site and the presence of P. laevigata, S. molle, and A. farnesiana as references. Total concentrations of 13 metal elements were determined using an inductively coupled plasma mass spectrometer (ICP-MS). The species were significantly affected by Co, As, and Pb (ANOVA, p≤0.05). Considering the land use and the species, the contents determined in the leaves and fruits of the three species had sufficient and phytotoxic contents of Al, Cd, Co, Ni, Mn, Ti, and Cr, and excessive ranges with the possible phytotoxic effect of As, Cu, Pb, Zn, V, and Fe. The A. farnesiana had the highest concentrations of 12 heavy metals analyzed (HM). The variation in total metal concentrations between leaves and fruits ranged from 84.70 to 99.06%, with V, As, and Cr being prominent. The functionality of these tree species as phytoremediators and bioindicators is reviewed to evaluate environmental impacts on land use. Highlights Tree species represent a potential bioindicator for studying environmental pollutants due to their ability to accumulate heavy metals. The variation in total metal concentrations between leaves and fruits ranged from 84.70 to 99.06% The contents determined in the leaves and fruits of the three species trees had sufficient and phytotoxic HM contents. The tree species have phytoremediators capacity to evaluate environmental impacts and environmental contamination of land use.

Abstract This paper presents the impact of salinisation on the aquatic mollusc fauna in flooded mine subsidences in the Karvina region (Czech Republic). The results of the previous research on salinity in flooded mine subsidences show that some of them contain a high content of dissolved inorganic substances (above 1000 mg·l-1). These substances can affect the vegetation and animals occurring in the water and the surrounding area. The phylum of Mollusca was selected as a model group for the fieldwork as it includes species with the proven bioindication potential. The occurrence of aquatic mollusc species was studied at 10 sites. The sites were selected based on the content of dissolved substances (the salinity gradient from <500 to >1000 mg·l-1. A total of 12 aquatic mollusc species were found, including one species identified as a potential bioindicator of the negative effect of salinisation on aquatic biota. The analysis showed statistically significant positive correlations between the content of dissolved inorganic substances and the presence of alien species Potamopyrgus antipodarum (J.E. Gray, 1843). The gradient of salinity significantly affects the species composition of the mollusc fauna in flooded mine subsidences and may affect the biodiversity of this group.

This study aimed to characterize the soil seed bank in an area dominated by Leucaena leucocephala, here called “Povoamento de Leucaena” (PL) and an area of native forest in the Parque Estadual do Rio Doce (PERD), both of which are affected by the city of Ipatinga, MG. Thirty sample units (SU) with dimensions of 25.0 x 25.0 x 5.0 cm were installed in each of the study areas and the seed bank of the areas was collected and evaluated. The emerging seedlings were counted and identified; the evaluations were carried out weekly during the six-month period. The average density of germinated seeds was 716.2 seeds/m² in the PL and 86.4 seeds/m² in the PERD area. In addition, 39 species were identified in the PL area (41% exotic), while in the PERD area 32 species were identified (25% exotic). The exotic tree species that stood out in number of individuals were Muntingia calabura and L. leucocephala, representing 82.57% and 5.88%, respectively of the total individuals found. Therefore, both environments are under strong environmental pressure, requiring the control of existing exotic species, as well as enrichment actions with the planting of species of diversity to accelerate the restoration process in the PL area.

Euglossini bees are recognized as orchid bees, they have a great importance as neotropical pollinators. Males are collectors of aromatic substances in flowers of several species of plants, but mainly of Orchidaceae. This tribe is composed of five genera, with the specie Eulaema nigrita Lepeletier considered in the group as a bioindicator species of degraded and anthropized areas. Thus, the objective of this research was to evaluate the abundance of the group in areas with different intensities of anthropic activity in the southern region of Mato Grosso do Sul, seeking to certify the proposal that the species El. nigrita can be considered a bioindicator, as has been mentioned sometimes. The samplings were carried out with pet bottle traps (transparent), with two side openings containing vanillin as an attractive bait. Four areas were evaluated, resulting in a total of 1226 specimens of El. nigrita collected, 687 (56.03%) in the forest area and 539 (43.96%) in the open field area. No significant difference was found between the two types of areas evaluated in relation to the average number of individuals from El. nigrita sampled (t = 0.8529; p = 0.4563). Thus, considering the different areas evaluated for areas designated as closed forests and open areas, the results obtained do not favor the idea that the species of Euglossini El. nigrita may come to be considered as a significant biological organism as a bioindicator of the state of natural conservation of the habitat considered.

Abstract The Batang Harau River was located in Nagari Paninjauan, X Koto District, Tanah Datar Regency, West Sumatra. The local community uses this river as a water source to carry out various daily activities, such as the irrigation of rice fields; household activities, and household waste disposal. The research aimed to analyze the comparison of dragonfly species diversity as a bioindicator for pollution in several habitat types (natural, rice fields, and settlements). The observations were made by exploring and walking along the river in the morning (9 am – 12 am) and evening (3 pm - 5 pm). The Visual Encounter Survey (VES) method was modified using a 20 m x 10 m plot, and all dragonflies found in this area were collected using an insect net. The data obtained were analyzed using the ShannonWienner diversity index, the Margalef species richness index, and Simpson’s dominance index. A total of 280 individuals, 12 species from 7 families, were collected in this study site. Most Odonata species were found in natural areas, followed by rice fields and settlements. The environmental conditions have affected the diversity of Odonata. The odonates can be used as bioindicators of the aquatic environment, especially in the suborder Zygoptera, which is dominantly found in natural habitats.

Bioindicator species are commonly used as proxies to help identify the ecological effects of oil spills and other stressors. However, the utility of taxa as bioindicators is dependent on understanding their trophic niche and life history characteristics, as these factors mediate their ecological responses. Seaside sparrows (Ammospiza maritima) and marsh rice rats (Oryzomys palustris) are two ubiquitous terrestrial vertebrates that are thought to be bioindicators of oil spills in saltmarsh ecosystems. To improve the utility of these omnivorous taxa as bioindicators, we used carbon and nitrogen stable isotope analysis to quantify their trophic niches at saltmarshes in coastal Louisiana with differing oiling histories. We found that rats generally had lower trophic positions and incorporated more aquatic prey relative to seaside sparrows. The range of resources used (i.e.,trophic niche width) varied based on oiling history. Seaside sparrows had wider trophic niches than marsh rice rats at unoiled sites, but not at oiled sites. Trophic niche widths of conspecifics were less consistent at oiled sites, although marsh rice rats at oiled sites had wider trophic niches than rats at unoiled sites. These results suggest that past oiling histories may have imparted subtle, yet differing effects on the foraging ecology of these two co-occurring species. However, the temporal lag between initial oiling and our study makes identifying the ultimate drivers of differences between oiled and unoiled sites challenging. Even so, our findings provide a baseline quantification of the trophic niches of sympatric seaside sparrows and marsh rice rats that will aid in the use of these species as indicators of oiling and other environmental stressors in saltmarsh ecosystems.

Ants are used as bioindicators because they play diverse ecological roles in terrestrial ecosystems. Their richness, abundance, and broad geographic distribution allow these insects to be used to predict the conditions of environmental conservation. This study aimed to evaluate the bioindicator potential of the ant fauna in Parque Estadual do Turvo, Rio Grande do Sul. Sampling was carried out in two events, in January and November of 2019, using soil and canopy pitfall traps, sardine baits, glucose baits, an entomological umbrella, and a sweeping net. We verified the association of ant species to the sampled strata (soil and leaf litter and vegetation) through an Indicator Species Analysis (ISA) and Principal Component Analysis (PCA). We identified 157 species belonging to 32 genera and eight subfamilies. The subfamily with the most outstanding richness was Myrmicinae, with 70 species, followed by Formicinae, with 40 species. The richest genera in the samples were Camponotus (S = 29), Pheidole (S = 23), and Linepithema (S = 11). Overall, 58 species occurred exclusively in the soil and leaf litter stratum and 23 in the arboreal stratum. Nine species had a significant indication value for the sampled strata, seven for soil and leaf litter, and two for the arboreal strata. The results show the potential of ant fauna as a basis for environmental impact studies and management and conservation plans in the southern Atlantic Forest biome.

Biomonitoring was proposed to assess the condition of living organisms or entire ecosystems with the use of bioindicators—species sensitive to specific pollutants. It is important that the bioindicator species remains alive for as long as possible while retaining the ability to react to the negative effects of pollution (elimination/neutralization of hazardous contaminants). The purpose of the study was to assess the survival of Pleurozium schreberi moss during exposure (moss-bag technique) based on the measurement of the concentration of elements (Ni, Cu, Zn, Cd, and Pb), chlorophyll content, and its fluorescence. The study was carried out using a CCM-300 portable chlorophyll content meter, portable fluorometer, UV-Vis spectrophotometer, and a flame atomic absorption spectrometer. As a result of the laboratory tests, no significant differences were found in the chlorophyll content in the gametophytes of mosses tested immediately after collection from the forest, compared to those drying at room temperature in the laboratory (p = 0.175 for Student’s t-test results). Mosses exposed using the moss-bag technique of active biomonitoring were characterized by a drop in the chlorophyll content over 12 weeks (more than 50% and 60% for chlorophyll-a and chlorophyll-b, respectively). Chlorophyll content in mosses during exposure was correlated with actual photochemical efficiency (yield) of photosystem II (calculated value of Pearson’s linear correlation coefficient was 0.94—there was a significant correlation between chlorophyll a and yield p = 0.02). The highest metal increases in mosses (RAF values) were observed for zinc, lead, and copper after the second and third month of exposure. The article demonstrates that the moss exposed in an urbanized area for a period of three months maintains the properties of good bioindicator of environmental quality.

The increasing use of dragonflies and damselflies as models in studies on biodiversity in the last decades has unraveled several features of natural processes and mechanisms for species conservation. Nevertheless, biodiversity is a polysemic concept that resolves multiple dimensions that, together, enroll what we observe as species and lineages diversity. One of these dimensions is Ethodiversity, which may represent the individual diversity of behavioral traits and higher organization levels. Hence, measures of Ethodiversity may be used as indicator tools to measure such dimensions of biodiversity. However, we still lack methods and protocols to measure this diversity. Therefore, here we addressed whether damselfly behaviors may act as indicators of environmental impacts. We collected behavioral data of 120 males in two sites, one in an ecological reserve and another in an impacted habitat. Our results show differences in behavioral syndromes and behavioral integrity when comparing populations in impacted and conserved environments. In conclusion, we hope that these results stimulate future endeavors to create a methodological framework to assess behavioral diversity.

AIMS: We evaluated the potential of aquatic macrophyte communities as bioindicators in six small shallow lakes. METHODS: The sampling was conducted monthly for one year, during which all macrophytes were surveyed, and the water temperature, dissolved oxygen, pH, conductivity, total alkalinity, chlorophyll-a, suspended matter, total nitrogen (Nt) and total phosphorus (Pt) were measured. RESULTS: In total, forty-three species were recorded, and there were significant differences in the species richness and limnological conditions among the lakes studied. A canonical correspondence analysis showed that the concentration of nutrients (Nt and Pt), chlorophyll-a, suspended matter, dissolved oxygen and pH were the most important predictors of the distribution of macrophytes. Some emergents were related to the high concentration of nutrients, chlorophyll-a, and suspended matter. Moreover, the most submersed species were associated with environments with low nutrient concentrations and the lowest values chlorophyll-a and suspended matter. In addition, some species submerged and floating were related to low values pH, alkalinity and dissolved oxygen. Limnological differences between lakes may be cited as the main causes of the observed heterogeneous distribution of macrophytes. CONCLUSIONS: These results indicate the importance of limnological characteristics of the different environments in the macrophyte community composition and the potential role of this community as a bioindicator in shallow lakes in southern Brazil.
