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.

Cytochemical and immunocytochemical investigations on epidermal mitochondria-rich cells in Salamandra salamandra salamandra (L.) larvae

Tissue and Cell, 1997
In the present study we set out to investigate the expression of E-cadherin, N-cadherin, beta 1-integrin, fibronectin and vitronectin in the mitochondria-rich cells (MRC) of the skin of Salamandra salamandra salamandra. Moreover MRC were stained with five lectins (Triticum vulgaris; Dolichos biflorus; Glycine max; Arachis hypogaea and Canavalia ...

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.

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.
