  • Freshwater ecosystems

    Freshwater ecosystems in Europe are rich in biodiversity and provide essential ecosystem services to humans Europe's freshwater ecosystems range from rivers, flood plains, lakes and ponds, marshes and peatlands, to man-made water bodies such as canals and reservoirs (EC, 2007a; EC, 2007b). They encompass a broad variety of wetlands. These different systems also interact with groundwater. ...

  • 10 messages for 2010 — Freshwater ecosystems

    Key messages Freshwater ecosystems in Europe are rich in biodiversity but at risk. They provide essential ecosystem services to humans, such as cleaning water, preventing floods, producing food, providing energy and regulating freshwater resources. Numerous pressures affect European freshwater ecosystems. Biodiversity has suffered from pollution and degraded water ...

  • Freshwater ecosystem management: from theory to application

    At the start of the 21st Century, humankind is struggling with many complex issues related to the management of freshwater resources. A key concern is that over-exploitation, in a world of increasing water stress, will result in environmental degradation, and loss of biodiversity and ecosystem services beneficial to humankind. "Ecosystem management" is one approach to managing natural resources, ...

  • The derivation of effects threshold concentrations of Pb for European freshwater ecosystems

    The main objective of the present study was to derive ecologically relevant effect threshold concentrations of (dissolved) Pb for selected European Union freshwater rivers, using the 2008 European Union Voluntary Risk Assessment Report (VRAR) as a starting point and using more advanced methodologies than those used in the VRAR. This included (i) implementing more robust quality criteria for ...

  • Kinds of freshwater and their relation to ecosystem services and human well-being

    The concept of ecosystem services (ESS) has evolved as a link between society and the environment and is recognized by both natural and social scientists. While this concept is increasingly being developed and applied to various ecological systems, it has not been defined specifically for different kinds of water. As water circulation is crucial for large-scale services, such as climatic and ...

  • Invertebrate community responses to a particulate‐ and dissolved‐copper exposure in model freshwater ecosystems

    Historical contamination has left a legacy of high copper concentrations in the sediments of freshwater ecosystems worldwide. Previous mesocosm studies have focused on dissolved‐copper exposures in the overlying waters which, due to altered exposure pathways, may not accurately predict the effects of copper exposure on invertebrate communities at historically contaminated sites. The present ...

  • Brackish Water as a Resource

    There’s a great deal of talk and debate about the value of treating brackish water, or water that is more saline than fresh water, but not quite as saline as seawater. Brackish water can result from the mixing of seawater with fresh water, as in surface waters such as estuaries or other watery ecosystems, or it can occur underground in aquifers. Salinity Levels Although ...

  • Study of environmental risks incurred by leakage of lithium cells to the food chain in a freshwater ecosystem

    Water flea (Daphnia magna) and fish (Carassius auratus) at trophic level were used for comprehensive evaluation of environmental risks incurred by manufactured nanomaterial (nNi(OH)2) as leaked from lithium cells to the food chain in freshwater ecosystem. The 48, 72 and 96 h acute toxicities of water suspensions of ...

  • Using species sensitivity distribution approach to assess the risks of commonly detected agricultural pesticides to Australia's tropical freshwater ecosystems

    To assess the potential impacts of agricultural pesticides on tropical freshwater ecosystems, the present study developed temperature‐ specific, freshwater species protection concentrations (i.e. ecotoxicity threshold values) for 8 pesticides commonly detected in Australia's tropical freshwaters. As relevant toxicity data for native tropical freshwater species to assess the ecological risks ...

  • Effects of air pollution on European ecosystems - Past and future exposure of European freshwater and terrestrial habitats to acidifying and eutrophying air pollutants

    Poor air quality not only harms human health; it also impacts the structure and function of ecosystems, often far away from the emission sources. This report focuses on the deposition of airborne sulphur (S) and nitrogen (N) compounds and their negative effects on ecosystems. N- and S-containing air pollutants are released to the atmosphere by combustion processes such as the burning of coal or ...

  • Mapping of freshwater aquifers case study

    Big Pine Key, Florida The Nature Conservancy is coordinating investigations to document the physical and biological changes that will occur on small oceanic islands as a result of sea level rise. Big Pine Key, FL is one of the primary areas of investigation because of extensive previous work and that a large portion of the island is a National Wildlife Refuge and therefore not subject to ...

  • Freshwater, climate change and adaptation in the Ganges River Basin

    Climate change is one of the drivers of change in the Ganges River Basin, together with population growth, economic development and water management practices. These changing circumstances have a significant impact on key social and economic sectors of the basin, largely through changes in water quantity, quality and timing of availability. This paper evaluates the impact of water on changing ...

  • Linking soil process and microbial ecology in freshwater

    Abstract Soil microorganisms mediate many processes such as nitrification, denitrification, and methanogenesis that regulate ecosystem functioning and also feed back to influence atmospheric chemistry. These processes are of particular interest in freshwater wetland ecosystems where nutrient cycling is highly responsive to fluctuating hydrology and nutrients and soil gas releases may be ...

  • A laboratory and in situ postexposure feeding assay with a freshwater snail

    Contaminant‐driven feeding inhibition has direct and immediate consequences at higher levels of biological organization, by depressing the population consumption and thus hampering ecosystem functioning (e.g., grazing, organic matter decomposition). The present study aimed at developing a short‐term laboratory and in situ assay based on the postexposure feeding of the freshwater snail ...

  • Freshwater quality — SOER 2010 thematic assessment

    Water is critical for life and is integral to virtually all economic activities, including food and industrial production. Not only is clean water a prerequisite for human health and well-being, it provides for aquatic habitats that support healthy freshwater ecosystems. A range of pollutants including nutrients, biocides, pathogenic micro-organisms, industrial and household chemicals, metals and ...

  • Physiological sensitivity of freshwater macroinvertebrates to heavy metals

    Macroinvertebrate species traits, such as physiological sensitivity, have successfully been introduced in trait‐based bioassessment approaches and are important predictors of species sensitivity in the field. The authors ranked macroinvertebrate species according to their physiological sensitivity to heavy metals using toxicity data from acute laboratory assays. Rankings for each of the heavy ...

  • Embracing uncertainty in freshwater climate change adaptation: A natural history approach

    Climate shifts are not new in the experience of humans and other species, but the capacity of potential evolutionary and ecological responses to climate change has been reduced through widespread human modifications of natural ecosystems. The magnitude, duration and timescales of altered climate threats require multigenerational strategies for climate change adaptation. In many places terrestrial ...

  • Invasive crayfish as vectors of mercury in freshwater food webs of the Pacific Northwest

    Invasive species are important drivers of environmental change in aquatic ecosystems, and can alter habitat characteristics, community composition, and ecosystem energetics. Such changes have important implications for many ecosystem processes, including the bioaccumulation and biomagnification of contaminants through food webs. We measured mercury in two non‐native and one native crayfish ...
