متن کاملComparison of active and passive sampling methods for detecting and monitoring the smooth newt (Lissotriton vulgaris) and the endangered northern crested newt (Triturus cristatus)
Amphibian populations are declining at an alarming pace in many parts of the world due to both global and local factors (Blaustein and Wake, 1995; Stuart et al., 2004; Beebee and Griffiths, 2005). Northern crested newt (Triturus cristatus) populations are declining in many European countries (Edgar and Bird, 2006; Denoël, 2012), while smooth newts (Lissotriton vulgaris) are still widespread and...
متن کاملThe sexual behaviour of the pygmy newt, Triturus pygmaeus
The courtship behaviour of pygmy newts, Triturus pygmaeus, consists of three phases: orientation, static display (often not clearly differentiated from each other) and spermatophore transfer. The repertoire of male sexual behaviour consists of nine different movements. Exhibition, an alert posture in which the male advances with small jumps around the female, is the most frequent behaviour. The...
متن کاملInduction and differentiation of an epithelial tumour in the newt (Triturus cristatus).
W A D D I N G T O N (1935) and later Needham (1936) have suggested that the autonomy of tumours originates in a 'morphological escape' of tumour cells from the controlling influence of an individuation field which has locally become weak or has vanished. The persistence and strength of such an individuation field can be seen in its ability to induce its parts to regeneration (Ruben, 1955). This...
متن کاملVariability of DNA methylation pattern in somatic and germ cells in male newt (Amphibia, Urodela) Triturus cristatus carnifex.
In a survey of several mammalian genomes, namely humans, rodents and bovines, the differences in the 5-methylcytosine (m5C) content show that repeated DNA sequences from sperm were undermethylated and from various somatic tissues were heavily methylated. This report shows a pattern of methylation in male newt (Amphibia, Urodela) Triturus cristatus carnifex (T. c. c.) unlike that so far describe...
