International audience; We describe the age structures of two neighbouring terrestrial salamander populations. The skeletochronological method was also used on larvae in utero and on new-born individuals. The age of adults was 8-24 years in populatio

Variations in life‐history traits in the common frog Rana temporaria (Amphibia: Anura): a literature review and new data from the French Alps
Autor: R. Guyetant, Johan Elmberg, Claude Miaud
Publikováno v: Journal of Zoology. 249:61-73
Life-history traits of Rana temporaria were studied in an alpine French population and in the literature. In the living frogs, mean adult body length was greater in females than in males. Sexual dimorphism in body length was 0.109 using Lovich & Gibb

[Thermodynamic studies of ontogenic rhythms of energy exchange in the alyte (an anuran amphibian)]
Autor: J P, Herold, D, Pepin, R, Guyetant
Publikováno v: Comptes rendus des seances de la Societe de biologie et de ses filiales. 181(2)
The total energy flux in an Amphibian was measured using a microcalorimetric technique throughout different stages of development. Simultaneous records of the individual activity (actography) allowed us to study circadian rhythms and their variations

Publikováno v: Comptes rendus hebdomadaires des seances de l'Academie des sciences. Serie D: Sciences naturelles. 285(5)
In the anterior pituitary of Alytes obstetricans Tadpoles in premetamorphic stages, two cell types were localized by cytoimmunological techniques: orangeophilic cells secreting a prolactin-like hormone in the anterior and median region and erythrosin
