1. Paedomorphosis, a developmental heterochrony involving the retention of larval traits at the adult stage, is considered a major evolutionary process because it can generate phenotypic variation without ...

Organisms with complex life cycles are characterized by a metamorphosis that allows for a major habitat shift and the exploitation of alternative resources. However, metamorphosis can be bypassed in some ...

1. In lentic freshwater habitats, the composition of animal assemblages shifts along a gradient from temporary to permanent basins. When habitats with different degrees of permanence are at the scale of the ...

Evolutionary theory predicts that alternative trophic morphologies are adaptive because they allow a broad use of resources in heterogeneous environments. The development of a cannibal morphology is expected ...
Denoël, M. (2004). Feeding performance in heterochronic alpine newts is consistent with trophic niche and maintenance of polymorphism. Ethology, 110(2), 127-136.
The feeding performances of two heterochronic morphs of the Alpine newt Triturus alpestris were investigated in laboratory experiments. Although both morphs are able to feed in the aquatic habitat, the ...
Denoël, M. (2004). Terrestrial versus aquatic foraging in juvenile Alpine newts (Triturus alpestris). Écoscience, 11(4), 404-409.
Many species of newts and salamanders forage in both terrestrial and aquatic environments during their life. However, the relative benefits of the two foraging patterns remain unknown because all previous ...
Denoël, M., Schabetsberger, R., & Joly, P. (2004). Trophic specialisations in alternative heterochronic morphs. Naturwissenschaften (Die), 91(2), 81-84.
Polymorphisms are suspected of reducing competition among conspecifics in heterogeneous environments by allowing differential resource use. However the adaptive significance of alternative morphs has been ...

Facultative paedomorphosis is a polyphenism that has important evolutionary implications in promoting morphological differentiation and habitat use variation, and has occurred in several urodele species ...

Current evolutionary models suggest that the presence of heterogeneous habitats favours the evolution of polymorphisms. In such cases, alternative phenotypes can coexist because they use different resources ...

1. Facultative paedomorphosis is a polymorphism that has important evolutionary implications in promoting morphological differentiation and variation in habitat use. It occurs in several urodele species ...
Denoël, M., & Joly, P. (2001). Size-related predation reduces intramorph competition in paedomorphic Alpine newts. Canadian Journal of Zoology, 79(6), 943-948.
Evolutionary theory assumes that facultative paedomorphosis in newts and salamanders is adaptive in allowing either a younger age at maturity or resource partitioning between the heterochronic morphs. In newt ...

Feeding habits and micro-habitat use were compared between metamorphs and paedomorphs in a population of the Alpine newt, Triturus a. alpestris in the French Alps. This population occupies a deep Alpine lake ...
