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.

Capping the consumption of European households who consume most energy - those with the highest incomes and education levels - could achieve "considerable emissions reductions", according to a UK research team. This benefit could also be achieved by simultaneously increasing the consumption of the poorest and most vulnerable users. The analysis, published in Nature Energy, estimates that limiting the energy use of the top 20 % of consumers in 27 countries in Europe would reduce emissions from domestic energy consumption by 11.4 %, 16.8 % from transport, and 9.7 % from total energy consumption. The article states that the association between high income and high energy consumption is particularly strong in countries such as Spain, where income inequality is relatively high.

The Plenary of the Senate has approved this afternoon the Proposition of Law for the recognition of legal personality to the Mar Menor lagoon and its basin. The law, which was approved in Congress last July, comes from a Popular Legislative Initiative signed by more than 600,000 people.

According to a study off the coasts of France, Italy, Spain, Croatia, Slovenia and Greece, catches of threatened elasmobranchs are higher in partially protected areas than in unprotected areas, suggesting that small-scale fishing may be affecting these species.

Our landscapes urgently need proactive, adaptive, integrative management to enable rural development that is compatible in the medium and long term with biodiversity and ecosystem services. It is clear that unilateral and reactive management in the face of the challenges of global change is neither effective nor intelligent. And inaction is also a decision.

Glyphosate is one of the most widely used herbicides in the world. New work published in Science reveals that it significantly impairs the ability of bumblebees to maintain the temperature of their hive, a hitherto unsuspected effect that may lead to the decline of this already endangered species, which is essential for pollination.
