We report for the first time the occurrence of the venomous snake species Micrurus ibiboboca in the state of Minas Gerais, Brazil, based on a specimen collected in an Atlantic Forest area. This is the sixth record of a venomous coral snake in Minas Gerais and increases to 160 the number of known snake species in the state.

Introduction/Objective. A countrywide survey of venomous snakebites was never conducted in Serbia: the making of a central register was initiated only in 2018. We collected and analyzed the available data regarding venomous snakebites in the Uzice region (Western Serbia). The previous analysis from this hospital was published in 1968. Methods. We retrospectively analyzed the data regarding the venomous snakebite patients treated in the Uzice General Hospital between 2006 and 2018 and compared these with the data from the 1960s, from one more hospital in Serbia, and from two ex- Yugoslav countries. Results. In 13 years, 249 persons were treated. Of all cases, 10.4% were with inconspicuous symptoms (mild pain at the place of bite), 68.7% were with mild to moderate symptoms, and 20.9% were more or less severe. No fatalities were recorded. Conclusion. Although usually not a life-threatening issue, venomous snakebites are quite common and can cause serious complications. With proper education, many can be avoided. Also, bearing in mind not only the biodiversity per se but also the importance of snakes? venoms for the making of various medically important products, we emphasize the need for proper protection of all three venomous snake species in Serbia, namely Vipera ammodytes (nose-horned viper), V. berus (European adder), and V. ursinii (meadow viper).

The Mean

Venomous snakes are among the main sources of mortality for humans in rural regions, especially in tropical countries. In this study, a meta-analysis of quantitative community ecology studies on snake assemblages throughout the world was conducted in order to evaluate variation in the frequency of occurrence of venomous species and venomous individuals by habitat and continent. A bibliographic search was done by consulting “Google Scholar” and “ISI Web of Knowledge”. In total, 24,200 results were obtained from our bibliographic search, out of which 60 independent studies reporting raw and analyzable quantitative data from 81 distinct snake communities were retained and used for analyses. A snow-ball procedure was also used to uncover additional studies to include in the analyses. We gathered data on a total of 30,537 snake individuals, with an average of almost 30% of venomous individuals. The mean number of sympatric species was 19, whereas the mean number of sympatric venomous species was almost 5. Venomous snake species accounted for 24.4% of the total species in each community—almost the same as the overall percentage of venomous snake species known worldwide (about 24%). The frequency of occurrence of venomous individuals did not differ significantly between tropical and temperate snake communities, and the same was true for the frequency of venomous species within each community. Thus, the greater number of snakebites in tropical countries is not due to there being more venomous snake species or individuals. The total number of species and the number of venomous species observed in each community were positively correlated, and there was a significant difference among continents in terms of the mean number of species in each community. Within communities, there were inter-continental and inter-habitat differences in both the percentage of venomous species and in the percentage of venomous individuals. The Generalized Linear Model (GLM) revealed that the frequency of venomous species at a local scale depended only on the total number of species inhabiting a given site, whereas the frequency of venomous individuals within communities depended on both the total number of species and a habitat–continent interaction. Our meta-analysis could enable the appropriate authorities/agencies to take the relative abundance of venomous species/individuals within snake assemblages into consideration for a better positioning of the first aid centers in locations where snake antivenoms should be available.

Abstract The morphometry and diet of two sympatric species of Chironius (C. flavolineatus and C. quadricarinatus) from Brazilian Cerrado are described. The two snake species differ in external morphology, as Chironius flavolineatus was the largest species (body, tail and eyes) whereas C. quadricarinatus the heaviest. Each species also showed marked sexual size dimorphism. In terms of dietary ecology, both species feed exclusively on frogs with a heavy preference for hylids and may have tendency to eat small items, as noticed in other colubrine species. These two snake species showed a brownish colour pattern and exhibited no ontogenetic variation, suggesting that juveniles and adults use similar substrates. Chironius flavolineatus and C. quadricarinatus present a semi-arboreal habit, with active foraging behaviour, feeding in the ground most of time. Chironius flavolineatus uses higher vegetation for resting and, based on morphological results, seems to be more arboreal than C. quadricarinatus.
