Turtles (Testudines) form a monophyletic group with a highly distinctive body plan. The taxonomy and phylogeny of turtles are still under discussion, at least for some clades. Whereas in most previous studies, only a few species or genera were considered, we here use an extensive compilation of DNA sequences from nuclear and mitochondrial genes for more than two thirds of the total number of turtle species to infer a large phylogeny for this taxon. Our results enable us to discuss previous hypotheses on species phylogeny or taxonomy. We are thus able to discriminate between competing hypotheses and to suggest taxonomical modifications. Finally, we pinpoint the remaining ambiguities for this phylogeny and the species for which new sequences should be... |

We surveyed the herpetofauna from the Complex of Planalto da Ibiapaba (CPI), CE, Brazil, during two years, using five sampling methods and information available in the literature. The amphibians are represented by 38 species distributed into nine families. The reptiles found summed 84 species, distributed into 25 families. Most amphibians collected exhibited wide occurrence along CPI, where we recorded 24 species (63.2%), which occurred at least in 60% of the sampled environments. Reptiles showed a different pattern, since 52 species (62.6%) had a restricted distribution (up to two environments). Sixteen species out of 25 considered as rare in CPI are restricted to relict moist forests. We also applied a rarity-vulnerability index to determine the most... |

The Mission Radeau des Cimes to Petit Saut, French Guiana, offered the opportunity to study the herpetofauna of the canopy of the tropical rainforest, an area hardly studied sofar. Two localities at heights of 30 and 35 m could be studied, whereas data on a third site were obtained through information from other participants. The herpetological results of the research in the canopy were meagre. Only the frog Hyla leucophyllata (Beireis) and the lizard Mabuya bistriata (Spix) were observed in the canopy. Additionally the terrestrial herpetofauna was studied extensively and turned out to contain some species that had not been reported before from French Guiana. Also, for many species new distribution data within French Guiana were obtained. Le Mission Radeau... |

A specimen of Enyalius perditus Jackson, 1978 collected in a pitfall trap installed at the Parque Estadual do Ibitipoca, Municipality of Lima Duarte, State of Minas Gerais, Brazil, on 19 March 1997, showed a transversal rupture of the skin, on dorsum of posterior region of the head, just joining the ear openings. In captivity, the continuance of the shedding scain spent approxima-tely one hour and forty minutes. The pieces of skin were removed in the sequence: head, venter, arms and flanks, legs, tail, and finally the tip of the fingers. The removed skin was eaten at the end of each stage. |

The dietary compositions of two sit-and-wait lizard species, Hemidactylus mabouia and Phyllopezus pollicaris, which co-occur over rocky substrate and vertical rock walls in a perianthropic area of western Brazil, were described. Both species showed a generalist feeding pattern, feeding mainly on insects. The most frequent prey items in the diet of P. pollicaris were Coleoptera, Araneae and Homoptera whereas the most important were Coleoptera and Homoptera, respectively. For H. mabouia the most frequent prey items were Araneae followed by Coleopterae and Hemiptera, whereas the most important items were H. mabouia followed by Formicidae and Hemiptera. Our identification into broader prey-types categories (i.e., order or family-level) suggests that some... |

Sexual differentiation of the marine leatherback turtle is sensitive to temperature. Incubation of eggs below 29 degree C results in 100% males, whereas incubationa bove 30 degree C results in 100% potential females at hatching. Therefore, the threshold temperature lies between 29 and 30 degree C as has been found for other marine turtles (Caretta caretta, Chelonia mydas ). Among hatchlings from natural nests in French Guiana, 10% were males, 20% were potential females and 70% had an intermediate phenotype. The sand temperature at 60 cm of depth, near one nest, was recorded and was found to vary between 29 and 30 degree C during the presumed thermosensitive period. These results will be useful to marine turtle hatcheries which seek to manipulate sex ratios... |

Eighty-nine species of lizards, six of which polytypic (forming a total of 97 taxa), are presently known from Brazilian Amazonia. This number includes six species and one subspecies described as new to science in this paper: Stenocercus fimbriatus, Lepidoblepharis hoogmoedi, Leposoma osvaldoi, L. snethlageae, Tretioscincus oriximinensis, Tupinambis longilineus, and Anolis nitens tandai. Stenocercus dumerilii is resurrected from the synonymy of S. tricristatus. Bachia cophias is considered a junior synonym of B. flavescens. B. peruana is a new record from Brazil. Anolis nitens has priority over A. chrysolepis. The Amazonian Tupinambis is shown to be T. teguixin (of which T. nigropunctatus is a junior synonym). The name T. merianae should be used for T.... |

The Magdalena River Turtle (Podocnemis lewyana) is a Colombian endemic species, endangered due to human exploitation and habitat destruction. To date, this species is poorly known ecologically and data on its genetic diversity are lacking. Here we report on the first genetic survey of the species across its distribution range. We obtained mitochondrial DNA sequences (488 bp) of the cytochrome b gene from 109 individuals. Samples belong to populations located at several different localities, grouped in five regions, along the four main river basins: Magdalena, Cauca, San Jorge, and Sinú drainages. We found two haplotypes, which differ in only one nucleotide substitution and which are represented with different frequencies in the five geographic regions.... |

The morphological and molecular evidence for higher-level reptile relationships is reassessed, A combined analysis of 176 osteological, 40 soft anatomical, and 2903 (1783 aligned) molecular characters in 28 amniote taxa yields the traditional reptile tree. Synapsids (including mammals) are the sister taxon to all other amniotes, including all extant reptiles. Turtles group with anapsid parareptiles and fall outside a monophyletic Diapsida. Within diapsids, squamates and Sphenodon form a monophyletic Lepidosauria, and crocodiles plus birds form a monophyletic Archosauria. This tree is identical to the tree strongly supported by the osteological data alone when fossils are included. In a combined analysis the strong osteological signal linking turtles with... |
