| phylogeny, biogeography, and evolution of two mediterranean snakes, malpolon monspessulanus and hemorrhois hippocrepis (squamata, colubridae), using mtdna sequences. | variation in 815bp of mitochondrial dna from two gene fragments (300bp of cytochrome b and 395-515bp of 12s rrna) for 26 malpolon monspessulanus, and cytochrome b for a further 21 individuals, indicates that this species originated in the maghreb area of northwest africa. here, an estimated 3.5-6mya, it divided into the western m. m. monspessulanus, and an eastern clade including m. m. insignitus and m. m. fuscus. the very limited genetic differentiation between maghreb and southwest european po ... | 2006 | 16679033 |
| epidemiology of venomous and semi-venomous snakebites (ophidia: viperidae, colubridae) in the kashan city of the isfahan province in central iran. | information on the epidemiology of venomous snake species responsible for envenomation to humans in iran has not been well documented. in the kashan city, venomous snakebite remains a recurring medical problem. information providing the correct identification of snake species responsible for envenomation in this geographic region would be useful to regional medical clinics and personnel for the effective and optimal management of the patients. | 2014 | 24672563 |
| does sexual selection influence ornamentation of hemipenes in old world snakes? | in the present study, we investigated and documented the morphology of the male copulatory organs (hemipenes) in fifteen wide-ranging snake species. the species represent four families (boidae, colubridae, lamprophiidae, and viperidae) and ten genera. we applied the same preparation techniques for all species, successfully everting and expanding the organs completely. the detailed description of the general morphology of the male copulatory organs was based on 31 specimens. our data were compare ... | 2017 | 28622447 |
