Übertragung von Verhaltensweisen durch Transplantation von Anlagen neuroanatomischer Strukturen bei Amphibienlarven
2010
By replacing parts of the neural plate (prospective medulla oblongata) of Triturus vulgaris by neural ectoderm of Xenopus laevis larval chimaeras were obtained, which showed donorlike rhythmical movements of distinct parts of the visceral musculature according to the place of implantation. Especially the branchial region with its external gills showed rhythmical movements and is the special object of this investigation.
Gene flow rates in Yugoslavian populations of the smooth newt Triturus vulgaris
1992
Allozymic variation in 22 loci in several Yugoslavian populations of four subspecies of the smooth newt Triturus vulgaris, has been analyzed. The frequency of private alleles and the coefficient of genetic differentiation, FST, give very different indirect estimates of the effective number of migrants per generation, Nm. However, such Nm estimates, in most cases higher than 1, imply that gene flow between populations is large enough as to prevent differentiation by random drift. In the case of T.v. vulgaris, of which sixteen populations amply distributed through Yugoslavia were sampled, there is evidence that frequent extinction and recolonization processes might be responsible for the obse…
Egg and embryo proteins in European newts (genus Triturus) and their taxonomic potential
1987
AbstractPolyacrylamide disc electrophoresis was carried out on water soluble proteins of eggs and embryos of Triturus alpestris, T. boscai, T. cristatus, T. helveticus, T. marmoratus and T. vulgaris. "Major bands" and "minor bands" were defined and species specific phenotyps are described. The patterns of major bands proved to be rather constant during embryonic development up to approximately stage 30 (stretched tailbud stage). The method as used in this study is considered to be practical and relevant for diagnostic studies on Triturus species.
