Evolutionary Ecology July 2014. Amphibian reproductive modes are diverse and are characterised by complex adaptations, including vast variability in life history traits and different parental investment strategies. For instance, viviparity is rare in urodeles despite the potential ecological advantages gained in such populations by having semi-independency from water. The fire salamander, Salamandra salamandra, shows remarkable intraspecific variation in reproductive modes, with two strategies co-occurring: a common reproductive mode, larviparity (parturition of aquatic larvae), and a phylogenetically derived reproductive mode, pueriparity (parturition of terrestrial juveniles).
