Summary: Newts used to be among the natural typical aquatic predators of ponds and lakes across Europe. In Southern Europe and particularly in the Balkans, they express two alternative developmental pathways: metamorphosis and paedomorphosis (retention of gills at the adult stage). However, multiple fish introductions, including species as diverse as goldfish, mosquitofish or trouts were introduced in their habitats. By exerting both direct and indirect effects on newt populations, these fish caused their decline and for paedomorphs and several subspecies their extinction. There is yet some hope as management efforts can allow the resilience of newt diversity.
