| envenomation by montpellier snake (malpolon monspessulanus) with cranial nerve disturbances. | the montpellier snake (malpolon monspessulanus) is an opisthoglyphous snake rarely implicated in human envenomation because the anatomy of its venom apparatus is generally unsuitable for venom delivery to large mammals. the authors report one case of human envenomation by the montpellier snake in southern france. envenomation occurred under exceptional circumstances (finger of patient inserted deeply into the mouth of the reptile). the clinical picture was dominated by neurological symptoms (pto ... | 2007 | 17669456 |
| experiments on direct and secondary poisoning by fluoroacetamide (1081) in wildlife and domestic carnivores. | fluoroacetamide (1081 or f.a.a) is used in israel for field rodent control. experiments on direct and secondary, short and long term poisoning caused by 1081 were carried out. mongoose (herpestes ichneumon), hyena (hyaena hyaena), cats and dogs were susceptible. barn owls (tyto alba), buzzards (buteo buteo) and black kites (milvus m. migrans) were markedly resistant. barn owls tolerated total direct poisoning ranging from 6.8 to 10.9, and a final dose ranging from 0.8 to 2.0 mg/kg. in secondary ... | 1979 | 480523 |
| the secretion of duvernoy's gland of malpolon monspessulanus induces haemorrhage in the lungs of mice. | a toxic protein that induces death of mice with profuse bleeding from the nostrils was isolated from the secretion of duvernoy's gland of malpolon monspessulanus (colubridae). the toxic protein, referred to as cm-b, showed mainly one band on sds-page corresponding to a mol. wt of 24,000. its intravenous ld50 in mice was 1 microgram/g and i.v. injections of lethal or sublethal doses induced haemorrhage in the lungs. when injected into the skin of mice, however, the toxin was not haemorrhagic. cm- ... | 1992 | 1523684 |
| sense-organ-like parietal pits found in psammophiini (serpentes, colubridae). | in several psammophine snake species, small sense-organ-like pits have been discovered occurring on the top of the head. these pits show a heretofore non-described structure. in numbers of one to four per head, they are present in dromophis lineatus, malpolon monspessulanus, several psammophis species and rhamphiophis rubropunctatus, but not in all individuals which is unrelated to sex. the reason for their sporadic occurrence remains obscure. their equally obscure function is discussed in relat ... | 2003 | 12806836 |
| prenatal development of the sound transmitting apparatus in different embryonic stages of malpolon monsspesulanus (squamata-serpentes). | the developmental investigation of sound transmitting apparatus is important in understanding the ontogenetic processes behind morphological diversity. the development of sound conducting apparatus was studied in montpellier snake; malpolon monspessulanus at 6.5, 7.2, 8.3 and 9.3 cm total body lengths using light microscopy study. the columella auris firstly appeared as undifferentiated rod shape mesenchymal cells. as the growth proceeded, it chondrified and differentiates into two main parts. i ... | 2018 | 29340531 |
| snakes on the balearic islands: an invasion tale with implications for native biodiversity conservation. | biological invasions are a major conservation threat for biodiversity worldwide. islands are particularly vulnerable to invasive species, especially mediterranean islands which have suffered human pressure since ancient times. in the balearic archipelago, reptiles represent an outstanding case with more alien than native species. moreover, in the last decade a new wave of alien snakes landed in the main islands of the archipelago, some of which were originally snake-free. the identification of t ... | 2015 | 25853711 |
| loss of largest and oldest individuals of the montpellier snake correlates with recent warming in the southeastern iberian peninsula. | the effects of climate change on organisms are now being extensively studied in many different taxa. however, the variation in body size, usually shrinkage in response to increasing temperature, has received little attention regarding to reptiles. during past periods of global warming, many organisms shrank in size, and current evidence and experiments manipulating temperature have shown a biomass decrease in some organisms with increasing temperatures. here we test whether the body size of the ... | 2017 | 29492021 |
| 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 |
| factors influencing predator roadkills: the availability of prey in road verges. | road mortality is the most noticeable effect of roads on wildlife. road verges may provide important refuges for small mammals and rabbits, particularly when roads cross intensive agricultural or grazed areas. in these circumstances, the increasing use of verges by prey species may attract predators to road surroundings increasing the risk of roadkill. the aim of this study was to quantify the role of prey availability (small mammals and rabbits) on predator road casualties, taking into account ... | 2019 | 31279141 |
| non-front-fanged colubroid snakes: a current evidence-based analysis of medical significance. | non-front-fanged colubroid snakes (nffc; formerly and artificially taxonomically assembled as "colubrids") comprise about 70% of extant snake species and include several taxa now known to cause lethal or life threatening envenoming in humans. although the medical risks of bites by only a handful of species have been documented, a growing number of nffc are implicated in medically significant bites. the majority of these snakes have oral products (duvernoy's secretions, or venoms) with unknown bi ... | 2013 | 23462380 |
| 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 |
