Vitamin D3 (20 IU/100 g bw) was administered to the freshwater snake, Natrix piscator for 15 days. This treatment evokes hypercalcemia from day 3 to day 5. This response declines at day 10 and day 15. Vitamin D3 also induces hyperphosphatemia from day 5 till the end of the experiment (day 15).

This study was carried out to increase information about Ophionyssus natricis (Gervais, 1844) detected on the sea snake (Natrix tessellata). The mite individuals collected from the cage of a sea snake were brought to our laboratory by the owner of the snake. They werepreserved in 70% alcohol, and then the mites were mounted on slides in Canada balsam, after making them transparent in lacto phen...

Abstract We used a dataset of georeferenced photos 5,751 grass snakes from iNaturalist to evaluate subspecific variation Natrix natrix in coloration and pattern. Our results provide evidence that all four genetically delineated subspecies differ morphologically, although unstriped individuals N. n. vulgaris are difficult tell apart the nominotypical subspecies. The shows frequency dark body inc...
