  • Climate change affects biodiversity in inland waters

    There has so far been rather little research on the impacts of climate change on biodiversity in inland waters. The best studied group has so far been fishes. A group of scientists at the Finnish Environment Institute has now published in the internationally esteemed series Biological Reviews a study on the consequences of climate changes for various inland water organisms. In a warming climate, ...

  • Putting the `CSI` into CSIRO on world water day

    Potentially applicable to coastal ecosystems around the world, the technique is based on a custom-made DNA microarray (gene chip), which contains DNA sequences from over 42,000 organisms found at the bottom of oceans and estuaries. A significant proportion of this genetic information was derived from samples taken around Sydney Harbour. Using the chip, scientists can investigate how many and what ...

  • Decreasing nitrogen emissions will cause relatively fast reductions of impacts on ecosystems

    The negative effects of acidic deposition in Europe and North America on natural ecosystems have been reduced significantly over the past decades, but the impacts of nitrogen on ecosystems are still persistent. This is evident from research results presented in a recently published book written by nearly 100 experts from 15 countries, entitled ...

  • Water map shows billions at risk

    About 80% of the world's population lives in areas where the freshwater supply is not secure, according to a new global analysis. Writing in the journal Nature, researchers have compiled a composite index of 'water threats' including issues such as scarcity and pollution. The most severe threat category encompasses 3.4 billion people. Vörösmarty et al. state that conserving water ...

  • Forest Service and EPA Increase Coordination to Improve Water Quality

    The U.S. Forest Service and the U.S. Environmental Protection Agency (EPA) have agreed on new steps designed to improve water quality on National Forests and Grasslands.  On Friday, September 28, Forest Service Chief  Abigail Kimbell and EPA Assistant Administrator for Water Benjamin Grumbles signed today a Memorandum of Agreement that enables both agencies to increase coordinated ...

  • Female fish swap sex in polluted, low-oxygen water

    Hypoxia – low levels of dissolved oxygen – can cause genetically female fish to develop into males, new research has found. Hypoxia in aquatic environments is often the result of eutrophication, which is caused by pollution from human activities. The findings suggest that hypoxia could cause fish populations to collapse, with consequences for entire ecosystems. There are more ...

  • Northamptonshire river work will benefit people and wildlife

    An exciting project is underway to improve a Northamptonshire river for people and wildlife. The Environment Agency is working with four other organisations on the £48,000 project to improve habitats on the river Nene at Duston Mill on the southern outskirts of Northampton. Work will include altering the channel to improve habitats and create more diverse flows that will benefit fish, ...

  • What are the impacts of invasive alien species?

    The impacts of invasive alien species (IAS) can take many different forms, from ecological to socio-economic. A new review investigates how to define and quantify ‘impact’ and discusses the most successful strategies to reduce invasion risk and prevent different impacts. Biological invasions can substantially degrade ecosystems and IAS are listed among the primary causes of global ...
