Der Pilz Batrachochytrium dendrobatidis, von Experten kurz "Bd" genannt, dezimiert Amphibienbestände in der ganzen Welt. Unklar war bisher allerdings seine Herkunft. Ein internationales Forscherteam, in dem auch zwei UFZ-Wissenschaftler mitgearbeitet haben, hat nun eindeutig bestimmt, dass der Erreger ursprünglich aus Asien stammt. Von dort aus hat er sich weltweit verbreitet und etliche neue genetische Linien entwickelt. Dieser Prozess sei auch weiterhin im Gange und kann das Amphibiensterben sogar beschleunigen, warnen die Forscher im Fachjournal Science. Sie plädieren für ein Ende des internationalen Amphibienhandels, um die Verbreitung verschiedener Bd Linien zu unterbinden.
