This project is led by three researchers from Spain and the UK. For over 15 years we have worked together to study the disease Chytridiomycosis, and constitute the research group with the highest contribution to knowledge of this disease within Europe. Some of our contributions to the study of this disease have been published in high impact journals and are cited below. You can request the text of these and other publications by the authors by emailing: This email address is being protected from spambots. You need JavaScript enabled to view it.
Some examples of our most notable contributions include: the identification of the first case occurred in Europe in 1997 and a description at the genetic, phenotypic and virulence level, of a global hyper-virulent strain of the Chytridiomycosis fungus that causes amphibian disease in almost all parts of the world.
Since 1999 our research team has been working with the managers of the Sierra de Guadarrama, monitoring amphibian populations and undertaking conservation actions. In 2008 we launched the Centre for Captive Breeding of Threatened Amphibians of the Sierra de Guadarrama with the Ministry of Environment of the Community of Madrid and we supervise and direct the activities of the centre. This project is part of the amphibian conservation plan of the Centre for Research, Monitoring and Evaluation of the National Park.
