The Iberian wolf has continued to lose genetic diversity despite its population recovery

A new study led by EBD-CSIC points to the need for a rapid increase and redistribution of the populations on the peninsula to guarantee their survival. The researchers have detected that with the disappearance of the wolf in Sierra Morena, a unique DNA sequence typical of the population that inhabited this area has been lost

The Iberian wolf occupied at least 65% of the Iberian Peninsula in the mid-19th century, three times more than today

A scientific team led by the Doñana Biological Station - CSIC reviews historical documentation to estimate the distribution of the wolf in Spain in the 19th century
The results show that the wolf could be found in all the provinces and its presence was less frequent in flatter areas, more suitable for agriculture and with higher population density

Ice Age wolf DNA reveals dogs trace ancestry to two separate wolf populations

An international group of geneticists and archaeologists, led by the Francis Crick Institute, have found that the ancestry of dogs can be traced to at least two populations of ancient wolves. The work moves us a step closer to uncovering the mystery of where dogs underwent domestication, one of the biggest unanswered questions about human prehistory.

A new study reviews the biodiversity of the 16th century in Spain

A team from the Doñana Biological Station – CSIC has reviewed a exhaustive standardized historical survey (Relaciones Topográficas de Felipe II) with the goal of knowing which species inhabited the Iberian Peninsula at that time.

In the 16th century, bears and wolves coexisted with the Iberian lynx, wild asses still existed in Spain and eels were in every river. Data is collected in an open database for new research.

A scientific team conducted a review on the patterns and determinants of dispersal in grey wolves

Scientists from the Doñana Biological Station – CSIC has reviewed the cientific literature on the dispersal process in grey wolves (Canis lupus) and found a high variability within and among study areas on all dispersal parameters. They found that it is due to multiple individual, social and environmental determinants, but also due to methological research issues
