Abstract:
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.

Abstract:
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.

Abstract:
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.

Abstract:
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:
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:
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.

Abstract:
This paper argues that if the goal of slowing global ecological degradation, and of sustained improvement in aquatic ecosystem health is to be achieved, then a departure is required from the traditional, discipline-focused approach to aquatic ecosystem health research and management. It argues that a shift needs to be made towards systemic, integrative, and holistic approaches, drawing on diverse disciplines, with values and ethics as fundamental to such approaches. The paper proposes the systemic-relational (SR) ethical framework to aquatic ecosystem health research and management as an essential contribution to addressing the potential intractability of the continuing deterioration of aquatic ecosystem health. The framework recognises the centrality of values in aquatic ecosystem health management, and the role of ethics in negotiating, and constructively balancing, conflicting values to realise healthy ecosystems in social–ecological systems (SES). The implications of the framework in terms of the research-practice interface, decision making, policy formulation, and communication are discussed.

Abstract:
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.

Abstract:
Benthic algae a re one of the most important primary producers i n lotic ecosystems, and changes i n their community structure and function (e.g., metabolism) will influence other organisms at higher trophic levels or even the entire aquatic ecosystem through bottom-up effects. Since they are known to be sensiti ve to changes i n ambient conditions, benthic algae and especially diatoms have been widely used as i ndicators of environmental changes in aquatic ecosystems, particular ly i n E urope , through developi ng diatom-based indices. However, these indices have not been widely used i n other continents. Applications of such i ndices in Asia and Oceania first require testi ng to see whether the y can perform as reliable bioindicators across time and space, considering that aquatic systems are constantly changing in terms of their ambient environment such as water physical and chemical conditions. Nevertheless, few studies have been carried out to compare the environmental influences on benthic algal communities among different geographic regions, nor the influences at different spatial scales (e.g., catchment, reach, and habitat). F urthermore, few studies have considered how diatom indices perform compare with other commonly used bioindicators of aquatic ecosystem health.

Resumo: Os metais traço são utilizados na indústria e na agricultura e podem estar presentes em efluentes de mineração e esgoto. Assim, esses elementos atingem o ambiente e podem ser prejudiciais aos organismos, meio ambiente e às pessoas. Um monitoramento representativo é essencial para a gestão dos recursos hídricos e consequente prevenção à poluição. Monitoramentos convencionais da água algumas vezes podem não revelar a real condição do ambiente. Isto acontece devido às condições de lançamento e chegada dos poluentes ao sistema, à tecnologia disponível para quantificar a concentração e devido às características da própria substância monitorada. No caso dos metais traço, estes têm uma atração maior por outras partículas (sólidos suspensos, solo, sedimento, carbono orgânico dissolvido), as quais sedimentam, não permanecendo na coluna d'água. Outro fator a ser considerado é que as fontes de metais traço são geralmente intermitentes e as coletas são não contínuas. Além disto, os limites de detecção são altos e não detectam tais elementos na água. Desta forma, o biofilme é uma técnica alternativa de monitoramento, pois analisa o nível de contaminação em um intervalo de tempo. Para este estudo foram construídos dois amostradores. Amostras de biofilme, água e sedimento foram coletadas ao longo de oito meses para dois pontos de monitoramento, um na bacia do rio Barigüi e outro na bacia do rio Miringuava. Parâmetros de qualidade da água, granulometria e conteúdo de metais traço foram estimados. Os resultados mostram que o biofilme identificou os metais traço em praticamente todas as campanhas, enquanto que para as amostras de água isto não aconteceu. As amostras de sedimento representaram a poluição, porém não foi possível determinar o tempo da contaminação pelo método de coleta utilizado. O biofilme representou as diferenças no uso e ocupação do solo, representando poluição consistente com cada bacia hidrográfica. Palavras-chave: biofilme, metais traço, monitoramento, rio Miringuava, rio Barigüi.
Abstract: Trace metals are used in industries and agriculture and can be present in mining and sewer effluents. In such context, these elements can enter the environment and be very harmful to organisms, environment and people. A representative monitoring is essential for water resources management and, consequently, pollution prevention. Conventional water monitoring do not always show real environment condition. That happens because of effluent release conditions, pollution arrival system conditions, available technology to identify element concentrations and monitoring substance characteristics. Specifically for trace elements, they tend to adhere to other particles (suspended matter, soil, sediment, DOC) and deposit in riverbed. Other factor is that trace metal sources are usually from intermittent discharges and collections are not continuous. Besides that, usual techniques have high quantification limit and do not identify these elements in water. Thus, biofilm is an alternative monitoring technique for trace metals evaluation since it analyses contamination level in a time space. For this study, two biofilm samplers were constructed. Biofilm, water and sediment samples were collected for an eight month period in two monitoring sites, Barigüi and Miringuava watershed. Water quality parameters, granulometry, and trace metals content were estimated. Results showed that biofilm identified metals in almost every campaign, while water samples did not. On the other hand, sediment samples represented pollution but it was not possible to determine the contamination time by the used collection method. Biofilm also represented differences in soil use and occupation, representing consistent pollution potential for each basin. Keywords: biofilm, trace metals, monitoring, Miringuava River, Barigüi River.

Abstract:
As a result of research carried out within the last decade to assess the diversity of macroinvertebrates of the Salt River in the Western Cape Province, South Africa, surveys of macroinvertebrates of 20 sites on 11 selected rivers from the same mountain range source were undertaken. This was done to make a preliminary assessment of the conservation status of the rivers of this region. Aquatic insects from the orders Ephemeroptera, Odonata, Plecoptera, Megaloptera, Trichoptera and the dipteran family Simuliidae were collected using techniques to maximize the number of taxa found. The insects collected were identified to species level where possible. Water physicochemical parameters were recorded at all sites for each sampling trip to characterize these rivers and to establish a set of baseline data for future comparisons. These parameters included measurements made on site and analysis of the concentrations of all the major ions in water samples in the laboratory. Multivariate analyses including Principle Components Analysis and Canonical Correspondence Analysis were used to reveal patterns within the water physicochemistry and species distributional data. Results include the identification of 123 species from 70 genera and 30 families. A total of 31 species were found to be undescribed, of which 17 were not previously collected and are thus completely new to science. In addition, four of these species could not be placed into any known genus. The analysis of water physicochemistry showed a clear distinction between rivers of Table Mountain sandstone and Bokkeveld shale origin. Downstream effects of anthropogenic influences were discernable too. Distinct macroinvertebrate assemblages were found based upon stream order and water chemistry composition. pH proved to be the most important driver of invertebrate assemblage composition. The high levels of endemism of the macroinvertebrates found within the upper reaches of these rivers and their degree of ecological specialization make these systems a priority for the conservation of aquatic biodiversity on a national and global scale.

Abstract:
A major challenge of ecologists is to discover general mechanisms that explain how climate shapes ecological communities and ecosystems. Efforts have traditionally focused on direct effects, but a growing body of evidence suggests that indirect effects of climate, via altering species interactions, may be more important. Predators are often particularly vulnerable to environmental stress, thus effects of climate may cascade through ecosystems by altering top-down trophic interactions. In Costa Rica, where climate change is predicted to decrease the amount of precipitation, bromeliads contain aquatic insect food-webs largely controlled by the top predator, damselfly nymphs. Community composition varies with bromeliad size. Notably, top predators occur only in large bromeliads, possibly because the probability of drought stress decreases with bromeliad size. Thus, bromeliads are ideal systems to study the relative importance of direct and indirect effects of climate on community and ecosystem responses. To determine whether climate governs community composition directly, I regressed insect drought sensitivity, which I obtained experimentally, against insect habitat size sensitivity, which I calculated from observational data. To examine the importance of indirect drought effects from altered trophic interactions, I experimentally manipulated trophic composition and drought in mesocosms mimicking a single bromeliad leaf well and measured changes in community composition, decomposition, and water quality. Climate directly governed community composition at the scale of the bromeliad, as drought sensitivity strongly predicted habitat size sensitivity. At the scale of the leaf well, drought altered community composition and ecosystem properties indirectly by reducing top-down control from the top predator. Moreover, indirect effects of drought cascaded through the food-web to affect ecosystem functioning (decomposition) and state (water quality). These findings suggest that in complex habitats, such as bromeliads, direct (physiological) effects of climate may sufficiently explain community composition. However, in isolated habitats, such as a single leaf well in which dispersal is hindered, indirect effects of climate, via altered trophic interactions, may emerge and cascade through the ecosystem. The relative importance of direct and indirect effects of climate may thus depend on habitat scale.

Abstract:
Pharmaceutical industries are experiencing a steady increase in both their numbers and demands, leading to a significant rise in the amount of waste they generate. This waste comprises various components such as organic compounds, excipients, and plastic containers. Unfortunately, a major portion of this waste is discharged into aquatic bodies through pipes, eventually reaching canal systems and ultimately the seas. This practice poses a severe threat to aquatic life, as it significantly impacts their habitat in a hazardous manner. One of the primary deleterious effects caused by pharmaceutical waste discharge is the elevation of the Biological Oxygen Demand (BOD) in the affected aquatic areas. This increase in BOD results in reduced oxygen availability for aquatic creatures, leading to mortality and ultimately causing a disruption in the natural balance of the ecosystem. Moreover, the accumulation of organic compounds from pharmaceutical waste leads to eutrophication, which accelerates the aging process of lakes, ultimately converting them into land. Another harmful consequence is biomagnification, wherein the concentration of toxicants increases as they move up the food chain through successive trophic levels. The continuous contamination of aquatic ecosystems by industrial waste is exacerbating the degradation of these fragile environments. However, the growing recognition of this issue has prompted research and implementation of various water treatment methods. These methods aim to mitigate the degradation rate and protect aquatic ecosystems from further harm. By employing advanced treatment techniques, it is possible to reduce the negative impact of pharmaceutical waste discharge and preserve the integrity of aquatic ecosystems. Efforts must be made to raise awareness among pharmaceutical industries about the importance of responsible waste management. By adopting sustainable practices and investing in environmentally friendly technologies, such as improved waste disposal systems and more efficient water treatment methods, the industry can significantly reduce its ecological footprint. Collaboration between regulatory bodies, environmental organizations, and pharmaceutical companies is essential to address this pressing issue effectively. With concerted efforts and a collective commitment to environmental stewardship, it is possible to mitigate the detrimental effects of pharmaceutical waste on aquatic ecosystems and safeguard the future of our planet's delicate aquatic habitats.

Abstract:
The current article presents a bibliographic overview of green infrastructures and their role in strengthening the adaptive capacity of aquatic ecosystems to the adverse effects of climate change (high temperatures, heavy rains, droughts). Different types of ecological infrastructures are presented: forest buffer strips, rain gardens, permeable pavement, drainage ditches; bioengineering structures for bank stabilization. Also the functions performed by green infrastructures to maintain ecosystem services were presented: mitigating the effects of floods, stabilizing banks, preventing landslides and water caused erosion, stormwater management, reducing the load of pollutants. For the implementation of this approach in the hydrographic basin of Dniester River or the Prut River a more detailed study is necessary on the state of habitats, identification of hotspot areas of aquatic biodiversity, particularly those species important for maintaining of ecosystem functions, highlighting of the areas at high risk of floods or erosion.

Anthropogenic pollution ;rnd e^TOph^t^ of aquatic ecosystems аге дЬЬа1 problems. Especi^ly important is the problem of reducing the quality of the already limited supply of fresh water. These problems have led to а wide range of studies in the field of monitoring of water ecosystems, which allows us to assess the ecologicd state of the reservoir. The functioning of aquatic ecosystems is trgely determined by the anthropogenic ;rnd иаШта! input of biogenic elements from the environment, so to determine the environment^ sound norms of anthropogenic input of biogenic elements into the ecosystem of the reservoir, it is necessary to identify the features of the structure of phyto- ;rnd zooptnkton, macrophytes, as well as to determine the concentration of chem^l elements connmed in the water.

Abstract:
As part of the US Army Corps of Engineers (USACE) Continuing Authorities Program (CAP), Section 206 projects focus on restoring aquatic habitats for the benefit of fish and other wildlife. From 2017–2021, USACE Engineer Research and Development Center–Environmental Laboratory researchers in the Aquatic Ecology and Invasive Species Branch (ERDC-EL EEA) at the Lewisville Aquatic Ecosystem Research Facility (LAERF) collaborated with USACE Galveston District, The Nature Conservancy, US Fish and Wildlife Service, National Park Service, and local nonfederal sponsors—Brownsville (Texas) Public Utility Board and the City of Brownsville—to study restoration methods on former, naturally cut-off, channels of the Lower Rio Grande River. These aquatic ecosystems, locally termed “resacas,” are home to endemic plants and animals and are thus an important natural resource of national interest. This technical report documents the planning, design, construction, monitoring, and adaptive management activities throughout the Resaca Boulevard Resaca Section 206 Aquatic Ecosystem Restoration project. Methods and results for invasive species management—primarily Brazilian peppertree (Schinus terebinthfolia)—and aquatic and riparian vegetation establishment in endemic Texas ebony resaca forest, subtropical Texas palmetto woodland, and Texas ebony/snake-eyes shrubland habitats are discussed.
