Current economic activity leaves an alien species 'invasion debt'

Past economic activity is more likely to explain the current pattern of biological invasions across Europe than recent human activities, according to a new study. It can take several decades before a newly introduced species becomes established and spreads, which may mean that recent invasions caused by current economic activities could create an 'invasion debt' for future generations.

Do offset schemes protect biodiversity in the face of development?

Biodiversity offset schemes do not always fully compensate for loss of habitat due to development, new research suggests. Of 66 development projects in France with offset schemes, it was found that numbers of species in offset sites was on average five times lower than in the land destined for development. Furthermore, even endangered species were not always protected by these offset sites.

Seafloor trawling's ecological impacts revealed by simple sampling system

Trawling's impacts on marine ecosystems can be assessed using simple metrics which characterise easy-to-obtain samples of fish, new research suggests. The Portuguese study shows that groups of fish become dominated by fewer species as fishing intensity increases, while their total biomass declines. Moreover, in the most fished areas there were other noteworthy changes, such as substantial reductions in the proportion of sharks and rays.

Coordination across Member States benefits Eurasian otter conservation assessments

Species surveys should be standardised across Member State borders to assess conservation status accurately, a new study concludes. The researchers assessed the conservation status of the Eurasian otter across the Republic of Ireland–UK border, finding that it was favourable for the whole island of Ireland. This provides a case study of surveys designed to provide data that is comparable across borders, say the researchers.

Fishing ban enforcement is key factor in restocking fish in marine protected areas

Marine protected areas (MPAs) in which fishing is prohibited contain substantially more fish, including commercially valuable species, than either partially protected or unenforced MPAs, according to a recent survey of rocky reef fish in the Mediterranean Sea. This suggests that MPAs need to be highly protected to offer the best chance of recovery for fish stocks, say the researchers.

Bear hunting's hidden impacts on cubs is highlighted in new study

Hunting has obvious impacts on wild populations. However, new research concludes that for Scandinavian brown bears (Ursus arctos), it also contributes to the killing of cubs by adult males to increase the male's chances of mating with the cubs' mother. The researchers say that this indirect effect of hunting should be considered when developing sustainable hunting quotas and management plans.

Protected areas that allow access to local people also benefit wildlife

Protected areas that allow local people to use the resources in a sustainable way are better for biodiversity conservation than excluding people entirely, a new study suggests. In a review of over 160 scientific studies, the researchers found that protected areas which were managed to allow sustainable access yielded greater socioeconomic benefits. Importantly, those with greater socioeconomic benefits were also more likely to report biodiversity benefits.

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 entire range in Europe.
