"Dear
For several years, amphibian populations to cross a worldwide crisis unprecedented. In less than 30 years, over 120 species extinct and 435 appear to have sharply declined. Today, nearly one third of the 6,000 amphibian species recorded around the world are threatened with extinction. For comparison, one in eight birds and one in four mammals possess a comparable level of vulnerability. One of those responsible for this decline is an emerging infectious disease, chytridiomycosis, caused by the pathogenic fungus Batrachochytrium dendrobatidis. The Bullfrog introduced in France (in the Loir-et-Cher, in the Dordogne and Gironde) was positive for B. dendrobatidis. The first cases mortality associated with this disease are observed in the Pyrenees in the salamander and the Common Midwife toad.
To date, knowledge of amphibian diseases in France (Chytridiomycosis, Ranavirus.) Are very limited. In many areas, amphibians are disappearing without causes of death are clearly established and it is possible that mass mortality of amphibians occur while going unnoticed. Your cooperation is fundamental to better understand the situation of these diseases in France and thereby preserve the local batrachofauna.
If you watch (or have seen during years) of mortality of amphibians, without apparent cause, thank you notify us as soon as possible
. You can find web
