Samples of larvae, efts and adults of two conspecific populations of each species were considered, one with generalized life cycle, the other with paedomorphosis (in a T. carnifex population larvae had prolonged growth and metamorphosed during the following year). It was found that existence of an alternative life cycle rendered more complex Ontogenetic picture of allometric relations of individual morphometric features, particularity in T. vulgaris. In this species paedomorphic individuals followed Ontogenetic trajectories of larvae, while metamorphic adults deviated considerably from this trajectories. This was much less significant in T. alpestris, another species with high incidence of paedomorphosis, but also in T. carnifex, a species with less plastic life-cycle than both previous species. As in the American newts (Harris 1989), differences between non-transforming and transforming individuals in the genus Triturus in Ontogenetic paths of size and shape changes presumably developed relatively late in ontogeny. 收起
