  • Integrated Water Management in Senegal

    This past June the Wetlands International Supervisory Council met for the first time in Senegal where they made field visits to a number of sites, including the Ndiael Special Avifauna Reserve. The Ndiael area, a complex wetland of great value in the Sahelian zone of Africa, has over the last decades been degraded due to the diversion of water supplies upstream. The reduced water flows and ...

  • An integrated approach for urban water quality assessment

    This paper introduces an integrated approach for the assessment of receiving water quality and the relative contribution of the urban drainage system to perceived receiving water quality problems. The approach combines mass balances with relatively simple receiving water impact models. The research project has learned that the urban drainage system is only one of the determining factors with ...

  • 2011 At a glance

    Securing water for wetlands in the Sahel The Niger River is the lifeline for the droughtstricken Sahel region and enables the annual flooding of the Inner Niger Delta in Mali, that is vital to support 1.5 million fisherfolk and farmers, plus millions of migratory waterbirds. However, climate change, dams and large irrigation schemes are limiting the floods. In 2011, by highlighting ...

  • The use of novel biomarkers to determine dietary mercury accumulation in nestling waterbirds

    Mercury (Hg) depuration into growing feathers is a well‐studied phenomenon in waterbirds. Although the kinetics of Hg excretion in relation to molt and diet has been studied extensively, the relationship between the individual nutritional condition of nestlings and dietary Hg accumulation has not been investigated. In the present study, a body‐condition index (BCI) and nutritional condition index ...

  • Antibacterial and antiviral effectiveness of two household water treatment devices that use monobrominated hydantoinylated polystyrene

    Many different household water treatment (HWT) methods have been researched and promoted to mitigate the serious burden of diarrheal disease in developing countries. However, HWT methods using bromine have not been extensively evaluated. Two gravity-fed HWT devices (AquaSure™ and Waterbird™) were used to test the antimicrobial effectiveness of HaloPure® Br beads (monobrominated hydantoinylated ...

  • Immunological and reproductive health assessment in herring gulls and black‐crowned night herons in the Hudson–Raritan Estuary

    Previous studies have shown inexplicable declines in breeding waterbirds within western New York/New Jersey Harbor between 1996 and 2002 and elevated polychlorinated dibenzo‐p‐dioxins and polychlorinated biphenyls (PCBs) in double‐crested cormorant (Phalacrocorax auritus) eggs. The present study assessed associations between immune function, prefledgling survival, and selected organ chlorine ...

  • Hepatic and nephric mercury and selenium concentrations in common mergansers Mergus merganser from Baltic Region, Europe

    Mercury (Hg) and selenium (Se) concentrations and their relationships in wild aquatic vertebrates have been investigated in areas with appropriate or excessive Se levels, mainly in North America. Generally, total mercury (THg) is determined in biota, although piscivorous vertebrates are most affected by dietborne methylmercury (MeHg). Mercury detoxification is based largely on production of ...

  • Analysis of information sources on waterbird migration in the Azov–Black Sea region of Ukraine: bibliography, count results and ring recoveries

    The study of bird migrations, particularly waterbirds, is one of the most important areas of ornithological science, but is also very important for designing measures aiming to protect them along the entire African–Eurasian fl yway. In this context, it is vital to distinguish the value of each more or less large wetland area as stopover for migratory birds. One step in this direction is to ...
