Biotic Integrity index (IBI) is widely utilized for biomonitoring in aquatic ecosystems, especially in assessing aquatic ecosystem health worldwide. Environmental changes significantly impact the aquatic ecosystem’s health of Subang Reservoir, which consequently affects the aquatic biodiversity. This study was conducted to determine its ecosystem’s health by assessing the IBI of freshwater fish in Subang Reservoir. In this study, thirty-four metrics were firstly selected as candidate metrics, and later, these thirty-four metrics underwent several statistical tests such as range, responsiveness, redundancy, and metrics scoring to screen and select the most appropriate metrics. A final eight metrics were selected after the statistical analysis, and a total score of 24 indicated that the Subang Reservoir’s ecosystem shows some stress due to an imbalanced fish guild. This showed that the ecosystem’s health of Subang Reservoir is in fair condition. This is because of the limitation of fish entering Subang Reservoir. The implementation of biomonitoring can be improved by modifying and selecting the most appropriate techniques, and the usage of biomonitoring can be increased in Malaysia’s freshwater ecosystems. The result reported in this study can be used as a scientific base data for implementing biomonitoring.

The aquatic ecosystem is composed of aquatic flora and fauna which interact together in maintaining the aquatic ecosystem. Aquatic macrophytes are macroscopic forms of aquatic vegetation, including macro algae, mosses, ferns and angiosperms found in aquatic habitat. Macrophytes of freshwater ecosystems have diverse roles to play in the structure and functioning of these aquatic ecosystems. The depth, density, diversity and types of macrophytes present in a system are indicators of water body health. Aquatic vegetation can influence the water quality too. Macrophytes are considered as an important component of the aquatic ecosystem as the habitat and food source for aquatic life. Of all the biological treatments for controlling eutrophication, submerged macrophytes, has been recognized as being the most effective. This paper is a brief review of the diverse role of macrophytes in an aquatic ecosystem.

Indonesia possesses a potential and diverse biodiversity of plants that can be utilized as phytoremediation agents. One of the ecosystems frequently encountering pollution is the aquatic ecosystem. Therefore, this research is conducted to identify the diversity of aquatic macrophytes with the potential for water remediation efforts. The method employed is qualitative descriptive based on literature review. The literature study revealed 30 species of aquatic macrophytes, with 15 species prominently utilized for environmental remediation. Among these, Ipomea aquatica and Scirpus grossus emerge as the most widely employed aquatic macrophytes.

As humans increasingly alter the surface geomorphology of the Earth, a multitude of artificial aquatic systems have appeared, both deliberately and accidentally. Human modifications to the hydroscape range from alteration of existing waterbodies to construction of new ones. The extent of these systems makes them important and dynamic components of modern landscapes, but their condition and provisioning of ecosystem services by these systems are underexplored, and likely underestimated. Instead of accepting that artificial ecosystems have intrinsically low values, environmental scientists should determine what combination of factors, including setting, planning and construction, subsequent management and policy, and time, impact the condition of these systems. Scientists, social scientists, and policymakers should more thoroughly evaluate whether current study and management of artificial aquatic systems is based on the actual ecological condition of these systems, or judged differently, due to artificiality, and consider resultant possible changes in goals for these systems. The emerging recognition and study of artificial aquatic systems presents an exciting and important opportunity for science and society.

An important challenge of integrated water resources management (IWRM) is to balance water allocation between different users. While economically and/or politically powerful users have well developed methods for quantifying and justifying their water needs, this is not the case for ecosystems—the silent water user. A promising way of placing aquatic ecosystems on the water agenda is by economic valuation of services sustained by ecosystems. In developing countries, the livelihoods of rural people often depend directly on the provision of aquatic ecosystem services. In such situations, economic valuation of ecosystem services becomes particularly challenging. This paper reviews recent literature on economic valuation of aquatic ecosystem services in developing countries. “Market price” is the most widespread method used for valuating marketed ecosystem services in developing countries. “Cost based” and “revealed preference” methods are frequently used when ecosystem services are non-marketed. A review of 27 existing valuation studies reveals a considerable range of estimated total economic value of aquatic ecosystem services in developing countries, that is from US$30 to 3,000/ha/year. The paper concludes that economic valuation is vital for bringing ecosystems to decision-making agendas in developing countries and that great effort must be made to bridge the gap between scientists and decision makers.

Abstract An ecosystem perspective is interdisciplinary and holistic, recognizing the interconnections among ecosystem components. The ecosystem approach incorporates social, economic and environmental elements into its definition (Environment Canada 1995). In instances where ecosystem initiatives fail to generate the body of public and political support necessary to address complex issues, barriers can often be found in the ecosystem initiatives themselves. Systemic barriers to the restoration of aquatic ecosystems are generated by the reluctance of some initiatives to go beyond pure sciences and an inability to integrate social, economic and environmental interests. It is common practice to allow the issues at hand to define the scale of an ecosystem initiative. Experience has shown that the issues at hand can also define the appropriate level of engagement. This paper explores Level 3: Community-Based Ecosystem Initiatives and the qualities that enable Level 3 initiatives to avoid and overcome systemic barriers to the restoration of aquatic ecosystems.

The addition of stable isotopes (SI) of 13C and 15N has been used to study several aquatic processes, thus avoiding environmental disturbance by the observer. This approach, employed for the last three decades, has contributed to expanding our knowledge of food-web ecology and nutrient dynamics in aquatic systems. Currently, SI addition is considered a powerful complementary tool for studying several ecological and biogeochemical processes at the whole-aquatic-ecosystem scale, which could not be addressed otherwise. However, their contributions have not been considered jointly nor have they been evaluated with a view to assessing the reliability and scope of their results from an ecosystem perspective. We intend to bridge this gap by providing a comprehensive review (78 scientific publications reporting in situ 13C/15N additions at the whole-aquatic-ecosystem scale) addressing the main results arising from their use as tracers. Specifically, we focus on: (i) reasons for SI additions at the whole-ecosystem scale to study ecological processes, (ii) the paradigms resulting from its use and the insights achieved, (iii) uncertainties and drawbacks arising from these SI addition experiments, and (iv) the potential of this approach for tackling new paradigms. SI tracer addition at the ecosystem scale has provided new functional insights into numerous ecological processes in aquatic sciences (importance of subsidies in lakes; heterotrophy dominance in benthic food webs in lakes, wetlands and estuaries; the decrease in N removal efficiency in most aquatic ecosystems due to anthropogenic alteration; the recognition of hyporheic zones and floodplains as hot spots for stream denitrification; and high rates of internal N recycling in tidal freshwater marshes). However, certain constraints such as the high cost of isotopes, the maintenance of the new isotopic steady state, and avoidance of biomass changes in any compartment or pool during tracer addition bear witness to the difficulties of applying this approach to all fields of aquatic ecology and ecosystems. The future development of this approach, rather than expanding to larger and complex aquatic ecosystems, should include other stable isotopes such as phosphorus (P18O4).

This paper presents an overview of the application of models on aquatic ecosystems. More than 17% of the models published in the focal journal in the field, Ecological Modelling, are aquatic ecosystem models. An increasing number of papers are dealing with the theoretical aspects of modeling – new modeling approaches and techniques, how models can be used to reveal ecosystem properties, and how models can better reflect the properties of ecosystems. This development implies that today we have more types of models. The characteristics, the advantages, and the disadvantages of these model types are presented briefly. The selection criteria for the presented model types are discussed, and the application of these types to models for aquatic ecosystems is reviewed. A recent improvement in model calibration of particular interest for aquatic ecosystems is presented, and the perspectives resulting from this new calibration procedure and from possible hybrids of the presented model types are discussed.

Nepal hosts a large area of freshwater aquatic ecosystem including glacier associated system like glacier-fed streams and lakes as well as stream fed lowland lakes. Bacteriological studies are very important in aquatic ecosystems as bacteria are the major participants in biogeochemical cycles and food web structures. This study reviewed available literature in bacteriological studies of aquatic ecosystems in the Central Himalayas, Nepal and revealed that such studies are very limited. Thus, we conclude that future research works need to proceed through the latest molecular methods with high throughput technique using multiple environmental factors in the aquatic ecosystem.

To date, various data on water resources have been accumulated, but hydrobiological and hydrochemical indicators remain available to assess the current state of aquatic ecosystems, which can be the basis for assessing the environmental situation within the water body. Systematization of multiyear and diverse data on the lakes and rivers of the country, the use of mathematical tools for assessing and forecasting the state of the aquatic ecosystem is impossible without the use of information and communication technologies. Quality mathematical modeling of aquatic ecosystems and the development of information and analytical system for the study of aquatic ecosystems is an urgent task, including databases of various-quality data on the water body and its ecosystem, data management and processing tools, as well as a set of mathematical models for the functioning of the water body ecosystem. Research is based on information technology, statistical data processing, and mathematical modeling. Mathematical models are based on systems of differential equations, solutions are sought with the help of own computing programs and software suites (Maple, Matlab, Mathematics, etc.). When possible, modeling includes analytical studies of the properties of solutions, primarily this concerns stationary or spatially homogeneous solutions, as well as asymptotic properties of solutions. The lower trophic levels of the water body ecosystem are studied, as this determines the functioning of aquatic ecosystems. The species composition of phytoplankton is an indicator of the ecological state of the water body. Based on the quantitative characteristics of phytoplankton, the bioproductivity of the aquatic ecosystem is calculated. The physical and chemical characteristics of water allow drawing conclusions about the pollution of the water body and the composition of mineral nutrition for phytoplankton.

Abstract. Invertebrate animals that live at the bottom of aquatic ecosystems (i.e., benthic macrofauna) are important mediators between nutrients in the water column and microbes in the benthos. The presence of benthic macrofauna stimulates microbial nutrient dynamics through different types of animal–microbe interactions, which potentially affect the trophic status of aquatic ecosystems. This review contrasts three types of animal–microbe interactions in the benthos of aquatic ecosystems: (i) ecosystem engineering, (ii) grazing, and (iii) symbiosis. Their specific contributions to the turnover of fixed nitrogen (mainly nitrate and ammonium) and the emission of the greenhouse gas nitrous oxide are evaluated. Published data indicate that ecosystem engineering by sediment-burrowing macrofauna stimulates benthic nitrification and denitrification, which together allows fixed nitrogen removal. However, the release of ammonium from sediments is enhanced more strongly than the sedimentary uptake of nitrate. Ecosystem engineering by reef-building macrofauna increases nitrogen retention and ammonium concentrations in shallow aquatic ecosystems, but allows organic nitrogen removal through harvesting. Grazing by macrofauna on benthic microbes apparently has small or neutral effects on nitrogen cycling. Animal–microbe symbioses provide abundant and distinct benthic compartments for a multitude of nitrogen-cycle pathways. Recent studies reveal that ecosystem engineering, grazing, and symbioses of benthic macrofauna significantly enhance nitrous oxide emission from shallow aquatic ecosystems. The beneficial effect of benthic macrofauna on fixed nitrogen removal through coupled nitrification–denitrification can thus be offset by the concurrent release of (i) ammonium that stimulates aquatic primary production and (ii) nitrous oxide that contributes to global warming. Overall, benthic macrofauna intensifies the coupling between benthos, pelagial, and atmosphere through enhanced turnover and transport of nitrogen.

Macrophytes are the main primary producers in lake ecosystems and are the main transmitters of material and energy flows in lake ecosystems, directly influencing the structure and function of lake ecosystems. The balanced harvesting of aquatic plants is a cost-effective scientific management approach to maintain ecosystem health. The article defines “balanced harvesting” as an aquatic plant harvesting technique to optimize the structure of aquatic plant communities, maintain the normal function of the ecosystem material cycle and energy flow, and enhance the stability and resilience of the system. The ecological significance of balanced harvesting in regulating the evaporation coefficient of the subsurface, reducing the accumulation and release of endogenous nutrient loads in lakes, delaying the evolutionary process of marshification, inhibiting biological filling, increasing biodiversity and system stability, and improving the environment of water bodies under the natural laws of adapted aquatic plants is reviewed. The way, time, and method of the balanced harvesting of aquatic plants in Baiyangdian, a grass-type lake in the north, were analyzed in order to provide an important reference for wetland ecological restoration and protection, maintaining the health of the aquatic ecosystem, and making the lake environment sustainable.

The hydrosphere represents about 71% of the total surface of the planet of which only 2.8% is represented by freshwater ecosystems. The ecosystem maintains a state of balance between the component populations, throughout its self-control function, maintaining the numerical variations of these populations within certain limits of sustainability. The exceeding of these limits could causes the balance disturbance by changing the structure and functioning of the ecosystem. The complex human activities influence the structure and functioning of ecosystems, transforming the environment and adapting it to its purposes. Microorganisms are present in all types of ecosystems, being endogenous, exogenous or transient due to contamination with various sources of pollution. Water is an essential natural factor of ecological balance increasingly exposed to microbial pollution. Indicators of fecal pollution are used to assess the degree of water contamination and to locate its origin. The continuous and uncontrolled usage of antibacterial agents that contributed to bacterial resistance determined/ caused pollution of aquatic ecosystems with antibiotic resistant microorganisms. The emergence of antibiotic resistant bacteria is predictable in any environment given that the use of antibacterial substances is constantly growing worldwide. Thus, antibiotic resistance induced in the aquatic environment can have an effect both on bacterial populations in the ecosystem and on human health. Aquatic environments are recognized as one of the reservoirs for the transmission and dissemination of antibiotic resistance. The main goal of this paper is to highlight the differences of bacterial communities from anthropogenic and natural aquatic ecosystems and to assess the potential impact they have on environment and human health. The study area focused on two lakes in Bucharest, Lake Morii (anthropic) and Lake Snagov (natural). Microbiological and molecular biology methods were applied for a bacterial communities’ characterization. The fecal indicators were quantified by Most Probable Number method. The identification and characterization of bacterial populations in both aquatic ecosystems (Morii Lake and Snagov Lake) were performed by Omnilog (Biolog, USA) and by iSeq100 (Illumina, USA) gene sequencing techniques from bacterial aquatic ecosystem. Antibiotic susceptibility was tested following CLSI recommendation.

This study is focused on investigating the variation patterns of macroinvertebrate guilds functional structure, in relation to the taxonomic one, across aquatic ecosystem types along the salinity gradient from freshwater to marine and the resulting implications on guild organization and energy flows. Synoptic samplings have been carried out using the leaf-pack technique at 30 sites of the aquatic ecosystems of the Corfu Island (Greece), including freshwater, lagoon, and marine sites. Here, we analyzed the macroinvertebrate guilds of river, lagoon, and marine ecosystems, as: i. taxonomic composition and population abundance ii. trophic guilds composition and relative abundance; and iii. body size spectra and size patterns. The following variation patterns across the three ecosystem types were observed: a. trophic guild composition and body size spectra were more conservative than taxonomic composition within and among ecosystem types, where, trophic guild and size spectra composition were more similar between river and lagoon ecosystem types than with marine ones; b. a dominance on resource exploitation of large species over smaller ones was inferred at all sites; and, c. higher body size-specific density of individuals was consistently observed in lagoon than in freshwater and marine ecosystems. Results extend previous findings suggesting a common hierarchical organization of benthic macroinvertebrate guilds in aquatic ecosystems and showing that lagoon ecosystems have higher energy density transferred to benthic macroinvertebrates than both freshwater and marine ecosystem types.

The study examines the terrestrial ecosystems component in Kano, Nigeria. The study employed direct digitization using latest Google Earth Image (version 10.3) and National Space Research Development Agency (NASRDA) land use map of the state. Simple descriptive statistics was also used to evaluate units of ecosystems indentified. The results revealed 16 ecosystems of land units within Kano terrestrial ecosystems. Mapping of the study area also revealed anthropogenic cultivation ecosystem Major category of 18,542km2 representing 89% while aquatic ecosystem covered a total 506 km2 with altitude elevation of 480above the sea level (a.s.l.). Shelterbelts and wind breaks were 458 - 498 a.s.l. with >100 approximate number of patches. Results were discussed and concluded as Kano ecosystem land use attributes revealed an interdependence of units with major terrestrial and minor aquatic ecosystems with the serious anthropogenic interferences which result in systemic loss of valuable units of ecosystems, ecosystem services and biodiversity components. Therefore, government should embark on mass awareness campaign on proper land use and sustainable environmental policies framework in the state should be enacted.

In general, water resources are becoming an invaluable resource that explains the sustainable development of any state. Rational use and protection of water sources is becoming one of the most pressing issues in our country. Pollution of water sources, in turn, affects the deterioration of water quality, living organisms that live in water sources (algae, fish, etc.), and the health of consumers. Since water is the most important resource in the world, it is a task to protect and prevent environmental risk. Therefore, to monitor the aquatic ecosystems of Akmola region, the research team conducted research in laboratory conditions, taking water samples from water bodies (Nura, Ishim Riversand Taldykol, Maybalyk, and Zhaltyrkol Lakes) from a practical trip organized by the research group. Research studies on water samples taken from water bodies showed that the water was polluted, and in some indicators the maximum rural concentration was exceeded. It is clear that pollutants affect water biota, although in most cases they are not the cause. According to water samples, the level of pollution of water sources was assessed. Protection of Water Resources in general from pollutants is one of the strategic tasks of the country.

The article is devoted to the scientific heritage of the outstanding Russian hydrobiologist A.F. Alimov. Showing a deep scientific interest not only in the problems of aquatic ecology, but also in zoology, he laid the foundations of the functional ecology of animals as a common area of interest for ecology and zoology. Further, his views were successfully used in studying functional ecology of different groups of aquatic animals and on their basis important generalizations were carried out on productivity and energy flows through aquatic ecosystems and communities. An important stage in his scientific work was the development of a structurally functional approach to the study of the functioning of ecological systems of water bodies and watercourses. He showed that their structural and functional parameters are naturally interdependent. This approach allowed quantification of changes in the ecosystems of water bodies exposed to various types of environmental stress. To describe the response of aquatic ecosystems to external factors, A.F. Alimov proposed an original interpretation of the steadiness and endurance of ecological systems. As a result, he laid the foundation for a quantitative assessment of the influence of various factors, including anthropogenic, on aquatic ecosystems. The proposed measures of steadiness and endurance of populations, communities, and ecosystems made it possible to assess quantitatively the degree of influence of factors on aquatic communities and the ecosystem as a whole. A.F. Alimov made a great contribution to the development of theoretical ecology. He gave an original definition of the ecosystem and formulated the main provisions of the theory of the functioning of aquatic ecosystems. Of great importance for ecology and biology in general are the works of A.F. Alimov on the territoriality of animals and on mechanisms that determine the number of species in aquatic ecosystems depending on the morphometry of water bodies, their trophic status, geographical location and degree of water mineralization. Of crucial importance for theoretical biology is a series of his works devoted to the biological (physiological) time of organisms. Based on strict mathematical analysis, he convincingly showed that organisms exist in their own internal time, the speed of which depends on the rate of the processes occurring in the body and is closely related to its mass.

The importance of developing and optimizing the structure of a modern payment system, which will facilitate not only the accumulation of these funds in the budget, but also to make relevant management decisionson their allocation for conservation measures and restoration of lost aquatic ecosystem functions was demonstrated. The methodological and theoretical basis of the study is the key concepts of modern economic theory, economics of environmental management and sustainable development, international ecosystem ecosystem accounting, institutional and neo-institutional theories related to the problem of scientific substantiation of payments for the use of resources and services of aquatic ecosystems. The key elements of the structure of payments for the use of water resources in Ukraine (rent for special water use, environmental tax for discharges of pollutants into water bodies, rent for water bodies, fines) are studied and analytical evaluation of these taxes were studied and performed their analytical evaluation. The main factors of low efficiency of payments for the use of aquatic ecosystem resources are identified. It is proposed scientific concepts to optimize the structure of payments for the use of resources and services of aquatic ecosystems taking into account the best models of international experience. Attention was focused on the necceserity of the creation in Ukraine a special extra-budgetary National Environmental Fund of Water Resources in the form of a legal entity, similar to the National Fund for Environmental Protection and Water Management in Poland, with the aim of accumulating payments for water ecosystem services and introducing tools to stimulate and support water protection measures. Perspectives for further research on this issue, in particular, with regard to the formation of a comprehensive strategic ecosystem approach to the introduction of payments for the use of resources and services of aquatic ecosystems, development of modern methodological approaches to assessing the services of aquatic ecosystems and formation of an optimal structure of payments for the use of water resources, taking into account their functional characteristics were identified.

Worldwide, aquatic ecosystems subsist on water leftover from agricultural, industrial, and municipal water uses. While bi-national agreements have temporarily provided water for the Colorado River Delta (Delta) in Mexico, dedication of water to support aquatic ecosystems is rare. High-level U.S. – Mexico negotiations are underway to consider whether and how to provide water for the Delta once the current pilot program ends in 2017. Better understanding of the value of aquatic ecosystems can be useful in securing water to sustain them. This paper reports research findings on values held by visitors from nearby Mexican communities for environmental flows in the Delta. Based on surveys conducted at five recreation locations, this contingent valuation methodology (CVM) study assesses visitors' willingness-to-pay (WTP) for an assured source of water to sustain the Delta's ecosystem and the recreational opportunities it provides. Results indicate strong support for Delta restoration, with the majority of respondents indicating positive WTP to ensure adequate amounts of water to sustain a healthy and vibrant Delta ecosystem. Econometric model results indicate a median WTP ranging from $97 to $168 MXN (approximately $7–$13 USD at the time of analysis) per car per entry. These values represent only a subset of recreational users, and recreation values are only one of many components of the ecosystem services provided by the Delta. While only a fraction of recreation value and total economic value, it is important to understand values held by local recreation visitors. These values gauge support for preserving aquatic ecosystems in nearby communities. Furthermore, values held in the local area affect water management and policy decisions regarding restoration of this unique aquatic ecosystem.

The unconsolidated earth surface is a rich source of minerals, of which clay is one of the richest natural minerals, having various natural and anthropogenic properties. Natural clay is widely available as a cheaper resource, which is non toxic to ecosystems and has the property of preserving ground water and aquifers. At the same time, the ubiquitous and widespread occurrence of clay will have the property to control toxic materials. The uncontrolled exploitation or mining of clay minerals will affect the aquatic ecosystem's sustainability in many ways. Water quality is very essential for the healthy environment and human life, whereas unpredictable conditions like flooding, drought, groundwater loss, loss of biodiversity, and health impacts on the surrounding inhabitants are some of the signs of ecosystem loss. The unwanted mined clay is deposited into the surrounding area of the mining environment, resulting in top soil, ground water, and surface water pollution. The review paper describes the pollution aspects of the aquatic ecosystem with special emphasis on ground water, aquifers, fresh water (lotic and lentic), sediment, and marine ecology and hydrology.

Abstract Biological invasions are a worldwide threat to the aquatic systems and have the potential to homogenize entire foodwebs and shift species abundance distributions to more skewed ones. Invasion impacts include effects on the foodweb structure and ecosystem functioning leading to a loss in native fish biodiversity and commercially important fisheries in many open water systems. The impacts of invasives are generally devastating as they spread in the foodweb with each species potentially interacting with multiple species. The foodweb modeling studies conducted in different inland aquatic ecosystems show that not all exotics cause a detrimental effect on the resilience of an ecosystem. Information on the foodweb structure and ecosystem properties is a prerequisite for formulating management protocols for conserving biodiversity, enhancement programmes and sustaining fisheries. The present paper reviews the impacts of invasive fishes in Indian aquatic ecosystems in the context of a changing foodweb scenario due to exotic fish species invasions. The information generated here could be applied for future research on similar ecosystems for deducing management actions.

Aquatic ecosystems are one of the most threatened ecosystems in the world resulting in the decline of aquatic biodiversity. Monitoring and the assessment of aquatic ecosystems are necessary to protect and conserve these ecosystems as monitoring provides insights into the changes in the aquatic ecosystem over a long period of time and assessment indicates the status of these ecosystems. This paper presents an overview of different methods for the hydromorphological, physical–chemical and the biological monitoring and assessment of surface waters. Furthermore, recently developed monitoring and assessment methods are discussed to support sustainable water management and contribute to the implementation of the Sustainable Development Goals 6 (SDG6 related to clean water and sanitation) and 15 (SDG15 related to terrestrial and freshwater systems) of the United Nations. However, many other SDGs are dependent on freshwater, such as food (e.g., SDG2) and climate-related SDGs. We presented an innovative concept for integrated monitoring and assessment. The main new elements are the monitoring of all communities and the use of integrated socio-environmental models to link these communities to ecosystem interactions and functions as a basis for determining their relation to the SDGs. Models can also allow to determine the effects of changes in SDGs on the different elements of the concept, and serve in this manner as tools for the selection of an optimal balance between the SDGs in the context of sustainable development.

Eutrophication is the term used to describe the presence of natural and artificial nutrients like phosphorus and nitrogen in aquatic ecosystems. The water quality in various bodies of water such as ponds, lakes, rivers, etc. is deteriorating as a result of an abundance of plant nutrients in these water sources. Over-enrichment of aquatic ecosystems with nutrients is a major hazard to the well-being of aquatic ecosystems worldwide. In addition, the circulations have lowered the requirements for home and agricultural consumption of water. The main origins of these plant nutrients within aquatic ecosystems stem from the discharges of industries engaged in activities like livestock farming, agriculture, fertilizer production, manufacturing of textiles, and clothing production. Therefore, a variety of methods and approaches have already been developed as safety measures to avoid the negative consequences of water tainted with those undesired minerals. Eutrophication presents many obstacles, but with the right public awareness campaign and global scientific efforts, its negative impacts may be lessened. This research seeks to pinpoint the primary origins of plant nutrients within the aquatic ecosystem and explore potential triggers for eutrophication. Additionally, it proposes innovative regulatory methods and offers suggestions for sustainable wastewater management practices.

Food chains and food webs describe the structure of communities and their energy flows, and they present interactions between species. Recently, diverse methods have been developed for both experimental studies and theoretical/computational studies on food webs as well as species interactions. They are effectively used for various applications, including the monitoring and assessment of ecosystems. This Special Issue includes six empirical studies on food chains and food webs as well as effects of environmental factors on organisms in aquatic ecosystems. They confirmed the usefulness of their methods including isotope, DNA-barcoding with gut contents, and environmental DNA for biological monitoring and ecosystem assessment.

SUMMARY The discovery that viruses may be the most abundant organisms in natural waters, surpassing the number of bacteria by an order of magnitude, has inspired a resurgence of interest in viruses in the aquatic environment. Surprisingly little was known of the interaction of viruses and their hosts in nature. In the decade since the reports of extraordinarily large virus populations were published, enumeration of viruses in aquatic environments has demonstrated that the virioplankton are dynamic components of the plankton, changing dramatically in number with geographical location and season. The evidence to date suggests that virioplankton communities are composed principally of bacteriophages and, to a lesser extent, eukaryotic algal viruses. The influence of viral infection and lysis on bacterial and phytoplankton host communities was measurable after new methods were developed and prior knowledge of bacteriophage biology was incorporated into concepts of parasite and host community interactions. The new methods have yielded data showing that viral infection can have a significant impact on bacteria and unicellular algae populations and supporting the hypothesis that viruses play a significant role in microbial food webs. Besides predation limiting bacteria and phytoplankton populations, the specific nature of virus-host interaction raises the intriguing possibility that viral infection influences the structure and diversity of aquatic microbial communities. Novel applications of molecular genetic techniques have provided good evidence that viral infection can significantly influence the composition and diversity of aquatic microbial communities.
