  • Linking Terrestrial and Aquatic Ecosystems: Complexity, Persistence and Biodiversity in European Food Webs

    The last years have witnessed the emergence of research in the field of complex networks. Complex networks describe a considerable amount of natural and social systems with a large, irregular, and changing in time structure, build up of thousands of nodes and ties between them. Certainly the continuous increase of computational power has supported the analysis of the wide databases of real ...


  • Attitudes of Europeans towards the issue of biodiversity

    The European Union (EU) is committed to the protection of 'biological diversity', i.e. the variability among living organisms from all sources including, inter alia, terrestrial, marine, and other aquatic ecosystems and the ecological complexes of which they are part; this includes diversity within species, between species and of ecosystems1. The EU has been legislating on biodiversity since the ...

  • Biodiversity Detectives Solve Mysteries with Environmental DNA

    For years, Monterey Bay Aquarium’s 1.2 million gallon main tank has been a source of thrill for visitors seeking fish-eye views of life in the pounding Pacific Ocean right outside its doors. Now, thanks to advances in DNA sequencing, it’s also becoming a model for how to survey life inthat vast ocean with just a few glasses of water. In a study published last January in ...

  • Rapid decline in biodiversity: a threat to survival of humankind

    Biodiversity, coined from two words; Biological Diversity simply refers to the variety and variability of life forms (plants, animals and micro-organisms) on earth. In other words, it is the totality of genes, species, and ecosystems in a region. Thus, biodiversity can be divided into genetic diversity within specie, Specie diversity within a community in an ecosystem as well as the more complex ...


  • Withdrawal of fresh water may reduce aquatic diversity

    Withdrawing fresh water from rivers and streams may adversely affect the health of fish and aquatic insects, according to a research team studying correlations between the two in North Carolina. The researchers, charged by the state of North Carolina and the state’s Department of Environmental Quality, investigated the relationship between changes in surface water flow and the diversity of ...

  • Communication of the European Commission to the Council and to the Parliament on a European Community Biodiversity Strategy

    INTRODUCTION 1. Biological diversity (biodiversity) is essential to maintain life on earth and has important social, economic, scientific, educational, cultural, recreational and aesthetic values. In addition to its intrinsic value biodiversity determines our resilience to changing circumstances. Without adequate biodiversity, events such as climate change and pest infestations are more likely ...

  • Overcoming water challenges through nature-based solutions

    Freshwater is a key resource and medium for various economic sectors and domestic purposes but its use is often at the expense of natural ecosystems. Water management must change to deal with urgent issues and protect aquatic ecosystems and their services, while addressing the demand for water from the competing claims for cities, agriculture, industry, energy and transport. In this paper key ...

  • Hampton Court - BritishFlora design sustainable planting solution for

    Royal Palace Waterways BritishFlora designed a sustainable solution for enhanced aquatic planting in the hard engineered waterways at Hampton Court. This is part of a wider pond and waterway restoration scheme across the Park to improve biodiversity, water quality, erosion prevention and aesthetics of these formal and natural water ways across Hampton Court. ...

  • Water quality monitoring in wetland ecosystems using microbial model communities

    This study reviews the concept of model communities for water quality assessment in aquatic ecosystems. The feeding habits of protozoans were used to unite species into functional, trophic groups. Colonising communities were dominated by bacterivorous Flagellate Species (Sf). A new Index of Periphyton Flagellates (IPF) as an indicator of the trophic status of a water-body was developed. ...

  • In search of effective bioassessment of urban stormwater pond sediments: enhancing the ‘sediment quality triad’ approach with oligochaete metrics

    Stormwater ponds have been widely used to control increased volumes and rates of surface runoff resulting from urbanization. As receiving waters, they are under the influence of intermittent pollution from urban wet-weather discharges. Meanwhile they offer new aquatic habitats balancing the transformation of initial ecosystems and their associated biodiversity. Bioassessment of stormwater ...

  • Beta diversity as a tool for determining priority streams for management actions

    Beta diversity has become essential for understanding ecosystem functioning and for determining biodiversity-conservation priority areas. However, the beta diversity patterns of invertebrates in tropical aquatic ecosystems are not well known, particularly in streams. Using data from low-order streams located in southern Brazil, we evaluated the beta diversity of Chironomidae. We tested the ...

  • A brief review on pollution and ecotoxicologic effects on Sundarbans mangrove ecosystem in Bangladesh

    The natural ecosystem of the Sundarbans mangrove wetlands is under threat due to anthropogenic activities. This ecosystem has become vulnerable to pollution such as oil spillage, heavy metals, and agrochemicals – which may have changed the mangrove ecosystem's biogeochemistry. In this paper, the present status of Sundarbans' mangrove pollution is reviewed. The ecotoxicologic effect on its aquatic ...

  • Case study - Singapore gardens an Environmental sustainability showcase

    Opened in spring 2012, Gardens by the Bay features an aquatic ecosystem with sustainable water cycles Singapore government officials’ vision to become a “city in a garden” came to fruition by redeveloping Marina Bay and boldly allocating prime land and a hefty budget for that purpose. Years of construction later, the Gardens by the Bay officially opened in the spring of ...

  • Global Monthly Water Scarcity: Blue Water Footprints versus Blue Water Availability

    Freshwater scarcity is a growing concern, placing considerable importance on the accuracy of indicators used to characterize and map water scarcity worldwide. We improve upon past efforts by using estimates of blue water footprints (consumptive use of ground- and surface water flows) rather than water withdrawals, accounting for the flows needed to sustain critical ecological functions and by ...

  • Macroinvertebrate community structure across a wetland hydroperiod gradient in southern New Hampshire, USA

    Abstract  We conducted a field study to examine the influence of hydroperiod and concomitant changes in abiotic (wetland size, pH, conductivity, dissolved oxygen and water temperature) and biotic (predatory fish presence) characteristics on macroinvertebrate communities in isolated wetlands in southern New Hampshire. Invertebrates were sampled using dipnet sweeps in 42 wetlands with short ...


  • Wetlands International Annual Review 2010

  • Re-oligotrophication as a challenge for tropical reservoir management with reference to Itaparica Reservoir, São Francisco, Brazil

    The process of reservoir eutrophication has been recognised as a central problem in tropical reservoir environmental quality. Effects of eutrophication are complex interactions involving a decrease in water quality, especially loss of aquatic biodiversity, occurrence of undesired species such as cyanobacteria with its cyanotoxins, mass development of macrophytes such as Egeria densa with its ...

  • 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 ...

  • Analysis of Selected Herbicides And Related Metabolites in a Coastal Lagoon Under The Influence of Water Runoff: Water Column

    Anthropogenic release of chemical contaminants, in particular pesticides coming from agricultural areas, significantly impacts European aquatic ecosystems. Pesticides and herbicides used in common agricultural practices, are applied only during specific periods of the year, leading to significant seasonal peak concentrations in fresh and coastal waters, particularly in spring after heavy rainfall ...
