Understanding trophic relationships is key to predicting species range shifts and protecting ecosystems. Researchers analyzed over three million localizations from approximately 3,000 bears, representing 14 European and Turkish populations

A new study shows a common pattern in the distribution of species globally. The discovery will help to understand life on Earth -including how ecosystems respond to global environmental changes

The role of the microbiota may determine the ability of mosquitoes to transmit disease. Bacteria from the families Burkholderiaceae and Erwiniaceae were predominantly identified. On the other hand, bacteria of the genus Wolbachia, which block virus replication in other mosquito species, were rare.

A study conducted by the Doñana Biological Station – CSIC and the University of Seville analyses how individual plants in various populations establish their interactions with the animals that consume their fruits. On average, a sigle individual attracts 70% of the diversity of frugivores animals present in its community, yet only a very small fraction of individuals play a central role in the network of interactions.

Since 2004, the Doñana Biological Station has used remote sensing to monitor changes and trends in the Doñana Natural Area at a landscape scale. Research continues to integrate new techniques and expand its capabilities. Doñana stands out for its potential to become an international calibration and validation site for remote sensing products.

A study by Ebro Delta Natural Park and the Estación Biológica de Doñana – CSIC highlights the severe decline of the European eel in recent years. The impacts of an invasive crab and inaction in fisheries management worsen the crisis of the European eel, considered a Critically Endangered species since 2008.

A study conducted by the Instituto de Salud Carlos III (ISCIII) and the Estación Biológica de Doñana (EBD-CSIC) has detected mosquitoes in Spain infected with Sindbis virus, a microorganism primarly hosted by birds and which can occasionally infect humans. The finding provides key information on the circulation of this virus in southern Europe and paves the way for further research to assess its potential impact on public health in Spain

This new study predicts that, without the Montaña del Río dike currently limiting tidal and river flooding, sea level rise would result in the inundation of the marshes with estuarine water during spring tides. These changes could have negative consequences, including the alteration of the aquatic plant community and the spread of invasive species, which would require a specific adaptation plan.

Researchers from the Estación Biológica de Doñana and the Centre de Recherche en Sciences Naturelles conducted a five-week scientific expedition into one of the least-explored rainforests of central Africa. The grey parrot is an endangered species, mainly due to decades of heavy trapping to supply international pet markets.
