Canarian Egyptian vulture was on the verge of extinction at the end of the 20th century. At that time, studies revealed that lead poisoning was a serious problem for the population’s survival. The work has been possible thanks to the monitoring carried out since 1998 by the Doñana Biological Station in collaboration with the Canarian authorities.

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

A research team of the Doñana Biological Station – CSIC has found that greater noctule bats, one of the most threatened bat species in Europe, do not change their shelter when facing predation risk.
The increase in these deaths might be related to the lack of alternative roosts due to the loss of habitat and breeding areas because of human activity

The data have been obtained from the long-term monitoring programs of six populations of Egyptian vultures (Neophron percnopterus) from Spain and France. The study makes it possible to advance in the knowledge of the natal dispersal of long-lived territorial birds, such as the Egyptian vulture.
The median dispersal distance was 48 km, while there were cases of movement longer than 500 km to settle as breeders. In addition, it was detected that females and males followed different...

Zoogeographical regions, or zooregions, are areas of the Earth defined by species pools that reflect ecological, historical and evolutionary processes acting over millions of years. Consequently, researchers have assumed that zooregions are robust and unlikely to change on a human timescale. However, the increasing number of human?mediated introductions and extinctions can challenge this assumption.
