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.

Biological recovery may lag behind chemical recovery in acidified Swedish lakes

The effects of climate change on seafloor ecosystems

Ocean warming driven by climate change will reduce the amount of food reaching marine life on the seafloor, a recent study suggests.

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.

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.

Device that emits natural warning calls reduces train-animal collisions

Animal-train collisions are an important cause of animal mortality. This study tested the ability of a device that emits natural warning calls to reduce risk of animals being hit by trains in central Poland.

Wetland biodiversity is supported by temporary flooding and sustainable grazing

The preferred habitats of wetland bird species - including 12 that are endangered - have been identified by a new study. From conducting counts at 137 sites across Sweden, it was found that total species richness was highest in sites that had a tendency to flood; wet grassland areas that were grazed as opposed to mowed; and sites that were far from areas of woodland.
