Ultrastructure of Epidermis of Salamandra salamandra Followed Throughout Ontogenesis

Cell and Tissue Research, 1977
Ventral epidermal ultrastructure of the amphibian urodele Salamandra salamandra is described and followed throughout its life cycle. Tadpoles were divided into five categories on the basis of the organization of their epidermis and the ultrastructure of its cells. In newly hatched tadpoles the epidermis is arranged in two layers and four types of cells

Projections to the Midbrain Tectum in Salamandra salamandra L.

Cell and Tissue Research, 1983
Following unilateral iontophoretic application of HRP into the optic tectum of Salamandra salamandra, retrogradely HRP-filled cells were found bilaterally in the pretectum, tegmentum isthmi, the reticular formation, pars medialis, and in the nucleus vestibularis magnocellularis.

Morphological differentiation of taste organs in the ontogeny of Salamandra salamandra

Anatomy and Embryology, 2001
Morphological studies presented here provide additional cytological evidence that in the postnatal development of Salamandra salamandra there are two successive generations of taste organs: premetamorphic taste buds (TBs) in larval forms and taste disks (TDs) in postmetamorphic animals.

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 ...

Sexual steroids in Salamandra salamandra (L.) during ontogeny

General and Comparative Endocrinology, 1991
In order to investigate the ontogeny of steroid secretions during the juvenile phase, sexual steroids were extracted and assayed after chromatographic separation in the gonads and plasma of male and female salamanders Salamandra salamandra L. at three characteristic postlarval stages. All specimens were collected in the wild.

Site Tenacity in the Terrestrial Salamandrid Salamandra salamandra

Journal of Herpetology, 2003
A six-year capture-recapture study allowed us to assess site-tenacity and spatial distribution of site-tenacious individuals in a population of the terrestrial, ovoviviparous Salamandra salamandra from Sintra-Cascais Natural Park, Portugal. The study area, an abandoned orchard, maintained large numbers of S. salamandra (about 400/ha).

Heimfindeverhalten bei Salamandra salamandra (L.)

Zeitschrift für Tierpsychologie, 2010
Homing behavior in salamanders (Salamandra salamandra) was studied in the field (52 adults) and in laboratory experiments (75 adult animals). Displacements, occluding of sense organs and experiments with different visual patterns revealed that the home-site orientation is guided by vision.

Trichromatic color vision in the salamander (Salamandra salamandra)

Journal of Comparative Physiology A, 1995
Spectral sensitivity functions were measured between 334 nm and 683 nm in Salamandra salamandra by utilizing two behavioral reactions: the negative phototactic response, and the prey catching behavior elicited by a moving worm dummy. The action spectrum of the negative phototactic response revealed 3 pronounced maxima: at 360–400 nm, at 520–540 nm, and

The innervation of the uterus in Salamandra salamandra (L.) (Amphibia, Urodela)

Cell and Tissue Research, 1983
The innervation of the uterus in the ovoviviparous urodele Salamandra salamandra was studied. In whole mount preparations of the thin-walled uterus of pregnant females, a dense adrenergic network was demonstrated using a modified glyoxylic acid fluorescence technique.
