  • How citizen science can help monitor data cold spots

    Effective conservation of the oceans relies largely on long-term monitoring of key species and habitats over wide geographical areas. This is notoriously difficult due to the high cost of such programs. As a consequence, we find ourselves with data ‘cold-spots’, areas for which we have little or no information. Citizen science, aka the involvement of volunteers or non-specialised ...

  • Presence of invasive American mink shifts the sex ratio of the European polecat across Europe

    The invasion of the American mink (Neovison vison) is linked to a shift in the adult sex ratio of the native European polecat (Mustela putorius) across its entire range, a new study has discovered. Through aggressive competition, the American mink has decreased the number of reproductive female European polecats. This is the first study to identify such an effect upon a native species across its ...

  • Invasive species: monitoring system aims to protect vulnerable Antarctic

    Better monitoring is needed to safeguard the Antarctic against threats posed by invasive alien species, according to a new study. The authors developed ‘the Antarctic Biological Invasions Indicator’ (ABII) to help generate data for tracking trends in alien invasions and the measures taken to prevent them. Invasive alien species are a leading threat to biodiversity. Currently, there ...

  • Djoudj National Park restoration an immediate success

    Djoudj National Park is a waterbird oasis located in the delta of the Senegal River separating Mauritania and Senegal. But invasive species are threatening to crowd out the birds. We recently witnessed how our small investment in restoration made a big difference for the birds and tourism. The question now is how can we sustain this progress by strengthening the funding model for the park? ...

  • Is Britain’s biosecurity being threatened by the risk of an ‘invasional meltdown’?

    Britain’s freshwater ecosystems are on the brink of an invasional meltdown, a new study concludes. Examining 23 freshwater species from south-east Europe, researchers investigated whether individual species in the group would ‘pave the way’ for others, resulting in a rapid increase in establishment of invasive species. The results showed that 76% of the interactions between the ...

  • Can US eliminate invasive species by eating them?

    It seems like a simple proposition: American lakes, rivers and offshore waters are filling up with destructive fish and crustaceans originally from other parts of the world, many of them potential sources of food. So why not control these invasive populations by getting people to eat them? The idea has gained momentum recently from the lionfish, which invaded the Gulf of Mexico but was ...

  • Invasive alien species’ impacts on ecosystem services: new tool to assess risks

    Researchers have developed a new risk assessment scheme for invasive alien species that not only predicts their direct effects on biodiversity, but also their impacts on ecosystem services. Furthermore, the scheme allows sources of uncertainty in a species’ impact to be identified, and can be applied to a range of different species. Invasive alien species are one of the greatest threats to ...

  • EPA Announces 11 Great Lakes Restoration Initiative Grants Totaling Over $5 Million to Combat Invasive Species in the Great Lakes

    The U.S. Environmental Protection Agency today announced the award of 11 Great Lakes Restoration Initiative grants totaling more than $5 million for projects to combat invasive species in the Great Lakes basin. “These Great Lakes Restoration Initiative grants will be used to target aquatic and terrestrial invasive species in the Great Lakes basin,” said Region 5 Administrator / Great ...

  • Environment: New EU action to protect biodiversity against problematic invasive species

    The European Commission today proposed new legislation to prevent and manage the rapidly growing threat from invasive species. There are currently over 12 000 species present in Europe which are alien to the natural environment. About 15% of these are invasive and they are rapidly growing in number. The proposal is designed to respond to increasing problems caused by these invasive alien species, ...

  • Effective tools to predict spread and improve monitoring of invasive alien species

    Effective surveillance and risk analysis are key to preventing the ecological damage caused by invasive alien species (IAS). Habitat suitability models provide highly effective tools for predicting the spread of IAS and guiding monitoring strategies, new research suggests. Along with habitat loss, IAS are a serious threat to European biodiversity, displacing native species and causing the ...

  • 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 ...

  • Mapping fish invasions in European freshwaters

    Detailed analysis of the patterns of invasion of alien fish species in Austria and Germany has highlighted how drivers of invasion, such as the animal trade, can change over time. The researchers who conducted the analysis warn that climate change may be a key cause in changing invasion patterns in the future. The invasion of alien fish species is known to be a major threat to the biodiversity of ...

  • Conservation managers and public unaware of invasive alien species’ true risks

    Neither the public nor conservation managers are fully aware of the different risks posed by invasive alien species (IAS), new research suggests. A study examining perceptions of five invasive species in the UK shows that both conservation managers and the public regard some highly damaging species as low risk’, and that their awareness does not increase with the amount of scientific ...

  • Socio-economic factors affect risk of alien species invasion

    Omitting socio-economic factors from invasive alien species (IAS) risk assessments could result in serious underestimations of the area at risk, new research suggests. Including factors such as population density and proximity to ports in risk assessments was found in this UK study to increase the size of the area predicted as suitable for invasion by up to six times. Species distribution models ...

  • Does the public’s view of invasive alien species differ from the professionals’?

    Key differences between public and professional opinions on invasive alien species (IAS) are highlighted by a recent UK study. Its authors recommend clearer, open discussion of the harm caused by IAS and human responsibility for their spread. Understanding public opinion regarding IAS is vital; in the past, public response to proposed IAS management has delayed action, occasionally even to the ...

  • Human population density explains alien species richness in protected areas

    Protected areas near densely populated towns and cities have higher numbers of alien species than those in more isolated locations, research suggests. In a South African study, researchers examined a number of different environmental characteristics of national parks, and found that surrounding human population density best explained the number of alien species in each park. There are many ...

  • Tackling Himalayan Balsam at Gundry Weir, Bridport

    An officer from the Environment Agency joined up with the Probation Service’s Community Payback Scheme to remove an invasive, non-native plant which is threatening the natural environment around a pond at Bridport. The Himalayan balsam grows up to 10ft (3m) tall and has colonised large areas beside rivers and woods throughout Britain, smothering any indigenous plants. This is ...

  • Making NY`s Lake George the world`s `smartest`

    An unprecedented project to turn New York's Lake George into the "smartest lake in the world" is being launched and will monitor the lake from its sun-dappled shores to its dark depths in hopes of keeping the Adirondack attraction pristine. Sensors analyzing the likes of stream runoff, rainfall, wind, currents, salinity, chlorophyll and nitrogen will be placed around Lake George this year and an ...
