EICAT+, a new framework to assess the positive impacts of alien species

The IUCN ENvironmental Impact Classification for Alien Taxa (EICAT) is a global standard to assess negative impacts of alien species on native biodiversity. However, alien species can also positively affect biodiversity.

Researchers from the University of Fribourg, the Doñana Biological Station – CSIC, and the Pyrenean Institute of Ecology – CSIC propose a new framework to assess these positive effects on native biodiversity to expand the understanding of the...

The economic costs of invasive alien ants total 46.000 million euros

An international scientific team led by the CSIC cuantifies the effects of the invasion of these insects in agriculture and public health
This work takes data from Invacost, the first database that compiles economic costs associated with biological invasions worldwide.

Las leyes de bienestar animal no deberían proteger a los gatos callejeros por comprometer la biodiversidad

Personal científico de distintas instituciones científicas españolas dedicadas a la ecología y la conservación ha publicado una carta alertando de los peligros para la biodiversidad del mantenimiento de gatos callejeros
Los gatos domésticos estuvieron implicados en la extinción de más de una cuarta parte de las extinciones de aves, mamíferos y reptiles en los siglos y son considerados los depredadores invasivos más dañinos.

Blue crab shows its invasive potential in the Ebro Delta

The blue crab colonized the Ebro Delta and surrounding waters in only two years of an exponential expansion, which started five years after the first detection. A study led by the Doñana Biological Station – CSIC and the Ebro Delta Natural Park shows that the expansion and the abundance increase of the blue crab have caused multiple, rapid and severe declines, including some affecting endangered species. The blue crab has rapidly become a keystone species in the Ebro Delta and can have...

The global economic costs of invasive aquatic crustaceans amounted to at least US$ 271 million

An international scientific team from Czech Republic, Spain, Germany, the UK, the USA, Italy, and France has compilled all existing published costs of invasive aquatic crustaceans and pointed out knowledge gaps.
Invasive crayfish and crabs had the highest costs, US$ 121 and US$ 150 million, respectively. Taxonomic, geographical, and temporal gaps suggest that these costs are still severely underestimated.
