Hypernatremia in Dice Snakes (Natrix tessellata) from a Coastal Population: Implications for Osmoregulation in Marine Snake Prototypes

Hypernatremia in Dice Snakes (Natrix tessellata) from a Coastal Population: Implications for Osmoregulation in Marine Snake Prototypes

The widespread relationship between salt excreting structures (e.g., salt glands) and marine life strongly suggests that the ability to regulate salt balance has been crucial during the transition to marine life in tetrapods. Elevated natremia (plasma sodium) recorded in several marine snakes species suggests that the development of a tolerance toward hypernatremia, in addition to salt gland de...

Study of Blood Parasites of the Three Snake Species in Iran: Natrix natrix, Natrix tessellata and Zamenis longissimus (Colubridae)

Infections with blood parasites are common phenomenon in reptiles from all over the world. Apicomplexan are the majority of blood parasites that frequently occur with high levels of parasitaemia in the snakes. The aim of this study was to determine the presence of blood parasites in some snakes Guilan province in the North of Iran. A total of 51 specimens of three snake species were captured in...

Nesting ecology of the grass snake (Natrix natrix) and its implications for conservation

Heterologous amplification of microsatellite markers from colubroid snakes in European natricines (serpentes: natricinae).

Eighteen microsatellite loci developed for a range of snake species (New World natricines, elapids, crotalids) were tested against European natricines (Natrix natrix, N. maura, and N. tessellata) in cross-species amplification experiments. Five loci were polymorphic (average expected heterozygosity 0.749 for a population of N. natrix in Amsterdam, mean sample size 47.8) and three loci were mono...

passivity in waiting for godot and endgame: a psychoanalytic reading

this study intends to investigate samuel beckett’s waiting for godot and endgame under the lacanian psychoanalysis. it begins by explaining the most important concepts of lacanian psychoanalysis. the beckettian characters are studied regarding their state of unconscious, and not the state of consciousness as is common in most beckett studies. according to lacan, language plays the sole role in ...
