    Alves et al. Journal of Ethnobiology and Ethnomedicine 2014, 10:30 http://www.ethnobiomed.com/content/10/1/30 JOURNAL OF ETHNOBIOLOGY AND ETHNOMEDICINE RESEARCH Open Access Students’ attitudes toward and knowledge about snakes in the semiarid region of Northeastern Brazil Rômulo RN Alves1*, Vanessa N Silva1, Dilma MBM Trovão1, José V Oliveira1, José S Mourão1, Thelma LP Dias1, Ângelo GC Alves2, Reinaldo FP Lucena3, Raynner RD Barboza4, Paulo FGP Montenegro4, Washington LS Vieira4 and Wedson MS Souto4 Abstract Background: Humans in various cultures have feared snakes, provoking an aversion and persecution that hinders conservation efforts for these reptiles. Such fact suggests that conservation strategies for snakes should consider the interactions and perceptions of the local population towards these animals. The aim of this study was to investigate students' perception of snakes and if attitudes and knowledge may differ according to gender and local residence (urban or rural). Methods: Data was collected in the second half of 2012 and consisted of questionnaires applied to 108 students in the Basic Education School in the municipality of Sumé, located in the semiarid region of Northeastern Brazil. Results: The male respondents recognized more species than female did. Part of the students affirmed to have a fear of snakes, especially women. Nearly half of respondents (49%) showed negative behaviour towards these animals, reflecting the influence of potential risk and myths associated with snakes, and supported by a limited knowledge about these animals and their ecological and utilitarian role. We find that the rural students recognized significantly more species than the urban students. Conclusions: Our results point to the need for educational interventions in order to increase knowledge about the positive aspects associated with snakes, seeking to minimize the influence of myths and beliefs that contribute to a strong aversion to snakes by the locals.

Throughout 2005, 26 specimens of snakes, 13 of P. nattereri and 13 of O. aeneus were collected. After anatomical dissection and laboratorial examination of the snakes’ respiratory tracts, P. nattereri was found to be parasitized by two species of pentas- tomids: Cephalobaena tetrapoda Heymons, 1922 with a prevalence of 30.8% and a mean intensity of infection of 51.5 ± 32.7 (range 3-147), and Raillietiella furcocerca (Diesing, 1863) which had a prevalence of 7.7% and a mean intensity of infection of 1.0.

The characteristics of the eggs, incubation time, and hatching are still unknown. This work describes for the first time the oviposition of 16 eggs by a female in captivity at Zoológico Nacional in Chile. After an incubation period of 59 days, seven neonates were born. We recorded data of biometry and ecdysis of these neonates for 9 months. In addition, a review about parameters of egg incubation and hatching for Philodryas species is provided.

FRANC¸A, F.G.R. Wild vertebrate roadkill in the Chapada dos Veadeiros National Park, Central Brazil. Biota Neotropica. 16(1): e0182. http://dx.doi.org/10.1590/1676-0611-BN-2014-0182 Abstract: Chapada dos Veadeiros National Park is one of the most important protected areas of the Brazilian Cerrado and is inhabited by diverse species, but the area has seldom been studied. From 2006 to 2008, we studied the impact of roads on wild vertebrates by recording roadkill on the two main roads located in the vicinity of the park. Of 824 killed vertebrates belonging to 138 species that were recorded, the species that were found most often in each vertebrate group were the Schneider’s toad (Rhinella schneideri), the grassland sparrow (Ammodramus humeralis), the yellow-toothed cavy (Galea flavidens), and the marbled lancehead (Bothrops marmoratus). The roadkill rate was 0.096 animals km-1. Vertebrate mortality was significantly higher during the wet season. There is a significant relationship between habitat structure and the vertebrates that were found as roadkill: amphibians are associated with nearby forest and paved roads, birds with nearby pastures, reptiles with nearby grassland, and mammals with unpaved roads.

THE REPTILE GUT MICROBIOME: ITS ROLE IN HOST EVOLUTION AND COMMUNITY ASSEMBLY A DISSERTATION SUBMITTED TO THE FACULTY OF THE GRADUATE SCHOOL OF THE UNIVERSITY OF MISSISSIPPI BY TIMOTHY JOHN COLSTON, MSC. IN PARTIAL FULFILLMENT OF THE REQUIREMENTS FOR THE DEGREE OF DOCTOR OF PHILOSOPHY CONFERRED BY THE DEPARTMENT OF BIOLOGY THE UNIVERSITY OF MISSISSIPPI MAY 2017 © Timothy John Colston 2017 ALL RIGHTS RESERVED ABSTRACT I characterize the endogenous (gut) microbiome of Squamate reptiles, with a particular focus on the suborder Serpentes, and investigate the influence of the microbiome on host evolution and community assembly using samples I collected across three continents in the New and Old World. I developed novel methods for sampling the microbiomes of reptiles and summarized the current literature on non-mammalian gut microbiomes. In addition to establishing a standardized method of collecting and characterizing reptile microbiomes I made novel contributions to the future direction of the burgeoning field of host-associated microbiome research.

South American racers of the tribe Philodryadini are a widespread and diverse group of Neotropical snakes with a complex taxonomic and systematic history. Recent studies failed to present a robust phylogenetic hypothesis for the tribe, mainly due to incomplete taxon sampling. Here we provide the most extensive molecular phylogenetic analysis of Philodryadini available so far, including 20 species (83% of the known diversity) from which six were not sampled previously.

  • Denisonia Hydrophis Parapistocalamus Toxicocalamus Disteira Kerilia Pelamis Tropidechis Drysdalia Kolpophis Praescutata Vermicella Echiopsis Lapemis
    The following is a work in progress and is intended to be a printable quick reference for the venomous snakes of the world. There are a few areas in which common names are needed and various disputes occur due to the nature of such a list, and it will of course be continually changing and updated. And nearly all species have many common names, but tried it simple and hopefully one for each will suffice. I also did not include snakes such as Heterodon ( Hognoses), mostly because I have to draw the line somewhere. Disclaimer: I am not a taxonomist, that being said, I did my best to try and put together an accurate list using every available resource. However, it must be made very clear that a list of this nature will always have disputes within, and THIS particular list is meant to reflect common usage instead of pioneering the field. I put this together at the request of several individuals new to the venomous endeavor, and after seeing some very blatant mislabels in the classifieds…I do hope it will be of some use, it prints out beautifully and I keep my personal copy in a three ring binder for quick access…I honestly thought I knew more than I did…LOL… to my surprise, I learned a lot while compiling this list and I hope you will as well when you use it…I also would like to thank the following people for their suggestions and much needed help: Dr.Wolfgang Wuster , Mark Oshea, and Dr. Brian Greg Fry.
