Scientists from the Doñana Biological Station – CSIC warns of the capacity of the blue crab to invade river stretches located far from river mouths. This migrating capacity of blue crabs introduce a new threat for native freshwater species, some of them highly threatened, such as the European eel, which was already in a critical situation before the invasion

Researchers from the Doñana Biological Station – CSIC have studied the changes in the distribution of the three species of crayfish introduced in Spain throughout history.
The study was based on historical sources to describe the evolution of the species distributions and the factors that may have influenced the process.

Researchers from 31 Spanish research institutions, coordinated by the InvaNET network and coinciding with the publication of the IPBES report, have identified the 108 alien animal and plant species with the highest risk of having a strong environmental impact in Spain in the next 10 years.

Those include, for example, the Japanese beetle, the roundworm Radopholus similis, or the marine plant Halophila stipulacea. More than 80% of the species identified are not included in the...

Un equipo científico entre el que se encuentra la Estación Biológica de Doñana y el Centro de Estudios Avanzados de Blanes utilizó información de más de 3500 muestreos de campo para detectar la presencia y describir la distribución de hasta seis especies diferentes de lochas introducidas en Cataluña
Los patrones genéticos demostraron que ha habido numerosas introducciones independientes y que una de las lochas invasoras que más se ha propagado, del género Barbatula, es una especie que...

The Doñana Biological Station – CSIC has shown the reliability of assessments of alien species impacts, which help prioritize resources against one of the current and future challenges of humankind.

These assessments based on responses by experts are susceptible of high subjectivity and it was essential to test their utility in assisting in the management of alien invasive species.
