We documented hypotheses on the evolution of developmental heterochronies by estimating short- and long-term advantages of alternative morphs. In this respect, we compared food energy intakes and body condition between paedomorphic and metamorphic Alpine newts (Triturus alpestris, Caudata, Amphibia) in four populations. Because we found a strong correlation between fat reserves and body condition, we used this last parameter as an indicator of long-term gains. In all studied sites, paedomorphic females showed higher body condition than metamorphic ones. Paedomorphic males were also at advantage in two populations. Paedomorphs exhibited higher energy intakes than metamorphs in two populations and similar gains in two others. Our results support unifying theories that predict the occurrence of facultative paedomorphosis in varied habitats as paedomorphs exhibited better energy balance than metamorphs. This work shows the need for considering integrative parameters such as body condition in the comparative study of performances when studying developmental heterochronies.

La mesure de la pression artérielle est probablement l'acte médical le plus souvent réalisé et certainement un des moins fiables. L'introduction de la mesure ambulatoire de la pression artérielle a permis d'identifier l'importance de l'effet consultatio et, par là, de définir l'hypertension de "la blouse blanche". Celle-ci se définit comme une pression artérielle pathologique à la consultation et strictement normale en dehors. Si on la définit de cette manière, cette pathologie ne s'accompagne pas d'une augmentation de la fréqunce des affections cardiovasculaires. Chez un tiers des patients, cependant, elle évolue vers des formes plus sévères de l'hypertension. [less ▲]

Phylogenetic relationships among 17 extant species of Murinae, with special reference to the genus Apodemus, were investigated using sequence data from the nuclear protein-coding gene IRBP (15 species) and the two mitochondrial genes cytochrome b and 12S rRNA (17 species). The analysis of the three genes does not resolve the relationships between Mus, Apodemus, and Rattus but separates Micromys from these three genera. The analysis of the two mitochondrial regions supported an association between Apodemus and Tokudaia and indicated that these two genera are more closely related to Mus than to Rattus or Micromys. Within Apodemus, the mitochondrial data sets indicated that 8 of the 9 species analyzed can be sorted into two main groups: an Apodemus group, with A. agrarius, semotus, and peninsulae, and a Sylvaemus group, with uralensis, flavicollis, alpicola, sylvaticus, and hermonensis. The position of Apodemus mystacinus is ambiguous and might be either included in Sylvaemus or considered a distinct subgenus, Karstomys, more closely related to Sylvaemus than to Apodemus. Estimation of the divergence time for these taxa suggests a separation between 7 and 8 My ago for the three groups (mystacinus and the two subgenera Apodemus and Sylvaemus). Within each subgenus, divergence times are between 5.4 and 6 My for Apodemus and between 2.2 and 3.5 My for Sylvaemus and mystacinus. [less ▲]
