Heterochromatic DNA in Triturus (Amphibia, Urodela)

Chromosoma, 1988
The MspI family of highly repeated sequences is a centromeric satellite DNA representing about 1% of the genome of the Italian smooth newt, Triturus vulgaris meridionalis. We have studied the structure, genomic organization, chromosomal localization and conservation across species of this family.

The lampbrush chromosomes of Salamandra salamandra (L.) (Amphibia Urodela)

Chromosoma, 1969
Lampbrush chromosomes isolated from the germinal vesicle of medium sized oocytes can be individually identified by differences in two characters: (1) chromosome regions rich in well developed loops, and (2) number and position of spheres. Actually the lateral loops are not all equally extended, but those which are inserted in a certain region of the ...

Feeding Ecology of Larval Ambystoma mabeei (Urodela: Ambystomatidae)

Southeastern Naturalist, 2004
Ambystoma mabeei is listed as threatened in Virginia due to its rarity and susceptibility to urbanization and poor forestry practices. The purposes of this study were to determine the composition of the diet of larval A. mabeei and to compare larval diet in different geographic regions to gain insights into the ecology of Virginia populations.

Reproduction en élevage de Euproctus platycephalus (Urodela, Salamandridae)

Amphibia-Reptilia, 1981
AbstractThis paper reports some observations on the reproductive behaviour of captive Sardinian Brook Salamanders (Euproctus platycephalus). Amplexus was observed frequently from October to May; eggs were preferentially deposited between stones ofvarious sizes or burried in the sand; egg-laying was spread over several months and had a maximum in spring;
