An international team of researchers has reconstructed the first European seed dispersal network based on a literature review. The data indicate that extinction threats and demographic changes in the animals that disperse them have resulted in 30% of plant species having their dispersers listed as 'high concern.' The lack of seed dispersal could hinder the recovery of declining plant populations. The authors publish their results in the journal Science. 

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.

Species of birds common in the marshes of Doñana as the common tern, the brown pochard, the marbled teal, the marsh harrier or the black-bellied sandpiper have recorded a decline in their population for more than a decade, a trend that accelerated since 2019. This is one of the conclusions of the Report on the conservation status of waterfowl in Doñana, published today by SEO/BirdLife.

The Participation Council of Doñana has analysed this Monday in an extraordinary meeting the bill presented in the Andalusian Parliament that aims to extend the legal irrigation in the area. The Andalusian Government maintains its support for the new regulation, which will begin its parliamentary debate tomorrow, Wednesday, with the proposal to take the bill into consideration. For his part, the director of the Doñana Biological Station, Eloy Revilla, in his speech to the Council warned of the general deterioration of the lagoon system and pointed out that "the current exploitation of the aquifer is not sustainable". "Spain has been condemned by the European Court of Justice for failing to comply with its obligations under the Water Framework Directive and the Habitat Directive," he said. The Ministry for Ecological Transition has warned that it will take the law to the Constitutional Court.

The draft Animal Protection Bill has just been approved by the Council of Ministers, awaiting ratification in Congress. The authors consider that the text includes improvements compared to its first version, but consider that it still contains negative aspects.

British ecologist Andy Green came to Doñana three decades ago inspired by the international fame and biodiversity of these marshes, an annual meeting point for millions of migratory birds. Today he is one of the researchers from five countries "urgently" warning that groundwater extraction and strawberry crops "seriously threaten" Doñana.

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.
