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.

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

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).

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.

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.

Plasma proteins and morphology of Salamandra salamandra in Israel

Amphibia-Reptilia, 1986
AbstractDifferences between three isolated populations of Salamandra salamandra were examined in this study. It is based on 369 adult specimens which were measured for length and weight. The yellow markings and the quantitative relationship between the black and the yellow areas were compared.

[Homing behavior in Salamandra salamandra (L.)].

Zeitschrift fur Tierpsychologie, 1980
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.

Electrophysiology and anatomy of direction-specific pretectal units in Salamandra salamandra

Experimental Brain Research, 1984
Pretectal cells of the European fire salamander were recorded extracellularly during binocular and monocular horizontal optokinetic stimulations. The locations of the individual units within the pretectal nucleus were verified with Alcian blue injections.
