| variability of alkaloids in the skin secretion of the european fire salamander (salamandra salamadra terrestris). | the two major alkaloids, samandarine and samandarone, were identified in the skin secretion of individual specimens from two populations of the european fire salamander (salamandra salamandra terrestris) by gas chromatography/mass spectrometry. high intraspecific variability in the ratio of both alkaloids was observed, but also in individual specimens over a period of 4 months suggesting separate metabolic pathways of the compounds. alkaloid synthesis appears to take place also in liver, testes ... | 2005 | 15777956 |
| causes of larval drift of the fire salamander, salamandra salamandra terrestris, and its effects on population dynamics. | the larval drift of the fire salamander was investigated over a period of three years in a mountain brook (niederbergisches land, f.r. germany), as well in a laboratory water channel. the rate of larval drift fluctuated between 19% and 41% of the total population of larvae in a defined section of the brook during these three years. most (83%) of the drifting larvae were hatchlings or very young stages. the drift was dependent on the strength of the current, the number of spawning females, the pr ... | 1990 | 28312673 |
