E-mail : [email protected] Abstract Most West Indian snakes of the family Dipsadidae belong to the Subfamily Xenodontinae and Tribe Alsophiini. As recognized here, alsophiine snakes are exclusively West Indian and comprise 43 species distributed throughout the region. These snakes are slender and typically fast-moving (active foraging), diurnal species often called racers. For the last four decades, their classification into six genera was based on a study utilizing hemipenial and external morphology and which concluded that their biogeographic history involved multiple colonizations from the mainland. Although subsequent studies have mostly disagreed with that phylogeny and taxonomy, no major changes in the classification have been proposed until now. Here we present a DNA sequence analysis of five mitochondrial genes and one nuclear gene in 35 species and subspecies of alsophiines. Our results are more consistent with geography than previous classifications based on morphology, and support a reclassification of the species of alsophiines into seven named and three new genera: Alsophis Fitzinger (Lesser Antilles), Arrhyton Günther (Cuba), Borikenophis Hedges & Vidal gen.

  • Snakes: Cultural Beliefs and Practices Related to Snakebites in a Brazilian Rural Settlement Dídac S Fita1, Eraldo M Costa Neto2*, Alexandre Schiavetti3
    Fita et al. Journal of Ethnobiology and Ethnomedicine 2010, 6:13 http://www.ethnobiomed.com/content/6/1/13 JOURNAL OF ETHNOBIOLOGY AND ETHNOMEDICINE RESEARCH Open Access ’Offensive’ snakes: cultural beliefs and practices related to snakebites in a Brazilian rural settlement Dídac S Fita1, Eraldo M Costa Neto2*, Alexandre Schiavetti3 Abstract This paper records the meaning of the term ‘offense’ and the folk knowledge related to local beliefs and practices of folk medicine that prevent and treat snake bites, as well as the implications for the conservation of snakes in the county of Pedra Branca, Bahia State, Brazil. The data was recorded from September to November 2006 by means of open-ended interviews performed with 74 individuals of both genders, whose ages ranged from 4 to 89 years old. The results show that the local terms biting, stinging and pricking are synonymous and used as equivalent to offending. All these terms mean to attack. A total of 23 types of ‘snakes’ were recorded, based on their local names. Four of them are Viperidae, which were considered the most dangerous to humans, besides causing more aversion and fear in the population. In general, local people have strong negative behavior towards snakes, killing them whenever possible. Until the antivenom was present and available, the locals used only charms, prayers and homemade remedies to treat or protect themselves and others from snake bites. Nowadays, people do not pay attention to these things because, basically, the antivenom is now easily obtained at regional hospitals. It is under- stood that the ethnozoological knowledge, customs and popular practices of the Pedra Branca inhabitants result in a valuable cultural resource which should be considered in every discussion regarding public health, sanitation and practices of traditional medicine, as well as in faunistic studies and conservation strategies for local biological diversity.

E-mail: [email protected]; [email protected]; [email protected]; [email protected] 2 Corresponding author. ABSTRACT. The swamp racer Mastigodryas bifossatus (Raddi, 1820) is a large snake of Colubrinae. It is widely distributed in open areas throughout South America. Dissection of 224 specimens of this species housed in herpetological collections of the southern Brazilian states of Rio Grande do Sul, Santa Catarina and Paraná provided information on its sexual dimor- phism, reproductive cycle and fecundity in subtropical Brazil. Adult specimens of M. bifossatus average approximately 1190 mm in snout-vent length and females are larger than males. The reproductive cycle of females is seasonal, with secondary vitellogenesis occurring from July to December. However, examination of male gonads did not reveal signs of reproductive seasonality in this sex. Egg laying was recorded from November to January. The estimated recruitment period extends from February to April. The mean number of individuals per clutch is 15, and there is a positive correlation between female length and clutch size. KEY WORDS. Fecundity; neotropics; reproduction; reproductive cycle; sexual dimorphism. Mastigodryas Amaral, 1935 belongs to Colubrinae and and fecundity of M. bifossatus (morphotype M. b. bifossatus) contains large-sized, generally robust species, active during the from subtropical domains of Brazil.

  • Reproductive Biology and Food Habits of the Swamp Racer Mastigodryas Bifossatus from Southeastern South America
    HERPETOLOGICAL JOURNAL 17: 104–109, 2007 Reproductive biology and food habits of the swamp racer Mastigodryas bifossatus from southeastern South America Otavio A.V. Marques1 & Ana Paula Muriel2 1Laboratório de Herpetologia, Instituto Butantan, São Paulo, SP, Brazil 2Departamento de Zoologia, Instituto de Biologia, Universidade Estadual de Campinas, Campinas, SP, Brazil The swamp racer Mastigodryas bifossatus is a large colubrid snake distributed mainly in open areas in South America. Dissection of 242 specimens provided data on body sizes, sexual size dimorphism, reproductive cycles and food habits of this species. Adult M. bifossatus average approximately 1100 mm in snout–vent length, with males and females attaining similar sizes. Reproductive cycles in females seem to be continuous, although oviductal eggs occur mainly from the beginning to the middle of the rainy season with peak recruitment at the end of the rainy season. Clutch size ranges from four to 24 and each newborn individual is about 300 mm SVL. Mastigodryas bifossatus is euryphagic, feeding mainly on frogs (44%) and mammals (32%). Lizards (16%), birds (4%) and snakes (4%) form the remaining prey. Relatively small prey (0.05–0.019) are ingested by adults, and juveniles eat mammals, which suggests that there is no ontogenetic shift in the diet of this snake. Swamp racers forage by day on the ground in open areas but may use arboreal substrates for sleeping or basking. Key words: Brazil, Colubrinae, diet, reproductive cycles, sexual dimorphism INTRODUCTION characterized by two distinct seasons: a dry season from April to August, with less rainfall and lower temperatures, he snakes of the subfamily Colubrinae are widely dis- and a rainy one from September to March, with higher Ttributed over all landmasses of the world, but are rainfall and temperatures (Nimer, 1989).

Truly stunning displays PPsittasitta By JAMIE GILARDI In mid-October I had the pleasure of visiting Bolivia with a group of avid parrot enthusiasts. My goal was to get some first-hand impressions of two very threatened parrots: the Red-fronted Macaw (Ara rubrogenys) and the Blue-throated Macaw (Ara SceneScene glaucogularis). We have published very little about the Red-fronted Macaw in PsittaScene,a species that is globally Endangered, and lives in the foothills of the Andes in central Bolivia. I had been told that these birds were beautiful in flight, but that Editor didn't prepare me for the truly stunning displays of colour we encountered nearly every time we saw these birds.

Conclusions Acknowledgments Glossary Bibliography Biographical Sketch Summary The main features that differentiate “reptiles” from amphibians are their dry scaled tegument andUNESCO their shelled amniotic eggs. In– modern EOLSS studies, birds are classified under the higher category named “Reptilia”, but the term “reptiles” used here does not include birds. One can externally identify at least, three groups of reptiles: turtles, crocodiles, and lizards and snakes. However, all of these three groups are made up by many species that are differentSAMPLE in some morphological characters CHAPTERS like number of scales, color, size, presence or absence of limbs. Also, the habitat use is quite variable; there are reptiles living in almost all the habitats of the Earth, but the majority of the species are only found in the tropical regions of the world. The West Indies is a region of special interest because of its tropical climate, the high number of species living on the islands, the high level of endemism, the high population densities of many species, and the recognized adaptive radiation that has occurred there in some genera, such as Anolis, Sphaerodactylus, and Tropidophis.

We also summarized data on lizard faunas for nine other well-studied areas in Amazonia to make pairwise comparisons among sites. The Biogeographic Similarity Coefficient for each pair of sites was calculated and plotted against the geographic distance between the sites. A Parsimony Analysis of Endemicity was performed comparing all sites. A total of 114 species has been recorded in the four studied sites, of which 45 are lizards, three amphisbaenians, and 66 snakes. The two sites between the Xingu and Madeira rivers were the poorest in number of species, those in western Amazonia, between the Madeira and Juruá Rivers, were the richest. Biogeographic analyses corroborated the existence of a well-defined separation between a western and an eastern lizard fauna. The western fauna contains two groups, which occupy respectively the areas of endemism known as Napo (west) and Inambari (southwest). Relationships among these western localities varied, except between the two northernmost localities, Iquitos and Santa Cecilia, which grouped together in all five area cladograms obtained. No variation existed in the area cladogram between eastern Amazonia sites. The easternmost localities grouped with Guianan localities, and they all grouped with localities more to the west, south of the Amazon River.

E-mail : [email protected] Abstract Most West Indian snakes of the family Dipsadidae belong to the Subfamily Xenodontinae and Tribe Alsophiini. As recognized here, alsophiine snakes are exclusively West Indian and comprise 43 species distributed throughout the region. These snakes are slender and typically fast-moving (active foraging), diurnal species often called racers. For the last four decades, their classification into six genera was based on a study utilizing hemipenial and external morphology and which concluded that their biogeographic history involved multiple colonizations from the mainland. Although subsequent studies have mostly disagreed with that phylogeny and taxonomy, no major changes in the classification have been proposed until now. Here we present a DNA sequence analysis of five mitochondrial genes and one nuclear gene in 35 species and subspecies of alsophiines. Our results are more consistent with geography than previous classifications based on morphology, and support a reclassification of the species of alsophiines into seven named and three new genera: Alsophis Fitzinger (Lesser Antilles), Arrhyton Günther (Cuba), Borikenophis Hedges & Vidal gen.
