Two-thirds of biological conservation actions improve biodiversity or slow its decline, a meta-analysis claims. The study highlights the effectiveness of interventions focused on invasive species control, habitat loss reduction and restoration, and protected areas. The article, published in the journal Science, brings together the findings of 186 previous studies.
Invasive species cause great damage to ecosystems, the economy and human health, but their impacts are underestimated. These are the main conclusions of a report published by the Intergovernmental Science-Policy Platform on Biological Diversity and Ecosystem Services (IPBES). Three researchers who participated in the document explained their results in an informative session organized by the Science Media Center Spain.
One of the world's most invasive species is Solenopsis invicta, an ant native to South America with a painful sting. In an article published in Current Biology, experts confirm the first official sighting of this species in Europe: 88 nests spread over five hectares near Syracuse in Sicily, Italy. The ants could soon spread across the continent, causing serious environmental, health and economic problems. The study is led by the Institute of Evolutionary Biology (IBE) of the CSIC and the UPF.
According to a new report from the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES), human activities have introduced over 37,000 exotic species to regions around the world. The document highlights that more than 3,500 of these are harmful invasive exotic species that are often overlooked until it's too late.
