| Microscopical investigations of the gut contents of six individuals of Dermochelys coriacea from southern England and the North Sea revealed the presence in all of these of numerous nematocysts, mainly scyphozoan. Only six species of Scyphozoa occur in British shallow waters and in the North Sea, viz., Pelagia noctiluca (Forskål), Chrysaora hysoscella (L.), Aurelia aurita (L.), Cyanea capillata (L.), C. lamarckii (L.) and Rhizostoma octopus (L.). For the purpose of comparison and identification an inventory was made of the cnidom of these six species (based on preserved material). Nematocysts of one or more of these species appeared to be present in each of the turtles, all six species being represented. One of the turtles in addition appeared to have... |

| Nesting activity of the neotropical turtle Phrynops hilarii Duméril & Bibron, 1835 was studied from Feb/94 through Jan/95, with weekly visits at the Lami Biological Reserve (30º15'S, 51º05'W), Porto Alegre, Rio Grande do Sul, Brazil. Nesting behavior was observed 17 times on three different nest sites. Phrynops hilarii laid in average 11 eggs per clutch (10-14; sd±1; n=17), nests' depth ranged from 100 to 150 mm (x=121.53 mm.sd±12.31; n=17). The species presents stereotiped behaviour common to other Testudines. Temperature inside the nest, just after nesting, ranged between 20-31ºC (x=26.29ºC; sd±2.89; n=17); nest predation during this period was 82.35% (14 of 17 nests). From Aug/29 through Oct/03/95, 220 egg shells was collected next to 21 nests... |

| Este estudio revisa la distribución para el Caribe colombiano de las especies Kinosternon scorpioides, Trachemys callirostris, Mesoclemmys dahli y Chelonoidis carbonaria y nuevas localidades en la distribución de dichas especies para la región. La especie K. scorpioides es registrada por primera vez en la cuenca del río Manzanares, en Santa Marta, Magdalena. Trachemys callirostris fue registrada en el río Cañas, La Guajira, constituyéndose en el primer registro para la especie en un riachuelo de la cara norte de la Sierra Nevada de Santa Marta. Chelonoidis carbonaria fue registrada en un humedal ubicado en la ciudad de Santa Marta. Se registró una hembra de M. dahli en el corregimiento Monterrubio, municipio Sabana de San Ángel, Magdalena. Tres de las... |

| ABSTRACT The citations contained in a recent literature review on the freshwater turtle and tortoise species of Colombia were analyzed. Publishing rates on these species have been increasing exponentially since the 1950s, although many of the publications would not be detected using internet-based literature searches. The most common topics of publications were systematics and phylogeography, nesting ecology, and management. In the 1970s and 1980s, the rate of publishing on the ecology and genetics of Colombian populations lagged behind the rate of publishing on these topics for populations of Colombian freshwater turtle and tortoise species located in other countries, but currently the production of the two regions is comparable. Also, in other countries... |

| 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... |

| The origin and evolution of the crown-group of turtles (Cryptodira + Pleurodira) is one of the most interesting topics in turtle evolution, second perhaps only to the phylogenetic position of turtles among amniotes. The present contribution focuses on the former problem, exploring the phylogenetic relationships of extant and extinct turtles based on the most comprehensive phylogenetic dataset of morphological and molecular data analyzed to date. Parsimony analyses were conducted for different partitions of data (molecular and morphological) and for the combined dataset. In the present analysis, separate analyses of the molecular data always retrieve Pleurodira allied to Trionychia. Separate analysis of the morphological dataset, by contrast, depicts a more... |

| ABSTRACT: We describe anti-Leptospira spp. agglutinin in yellow-spotted river turtles (Podocnemis unifilis)in the Amazon region. Ninety-eight serum samples from individuals housed at the Bosque Rodrigues Alves Zoobotanical Garden of Amazonia, Belém, PA, Brazil, were subject to the microscopic agglutination test (MAT) using 19 different Leptospira spp. antigen serogroups. Thirty-four of the 98 samples (35%) were reactive, with titers ranging from 100 to 3200, and eight 8 reactive samples (23.5%) co-agglutinated under two or more serovars.The most common serogroup was Hebdomadis (26.9%, 7/26), followed by Semaranga (23%, 6/26), Shermani (19.2%, 5/26), Djasiman (11.5%, 3/26), and Australis (7.7%, 2/26); Bataviae, Javanica, and Sejroewere represented by a... |

| Os dados sobre a fauna reptiliana em Minas Gerais são pontuais e revelam carência de informações sobre esse grupo, principalmente em regiões de transição entre a Mata Atlântica e o Cerrado. A área do estudo está situada no município de Ritápolis (21° 01' 37.07" S e 44° 19' 11.84" O), microrregião Campo das Vertentes, Estado de Minas Gerais, Sudeste do Brasil. Pretendeu-se com a presente pesquisa conhecer a composição da fauna de répteis local. As observações, capturas e coletas foram realizadas quinzenalmente, durante dois dias consecutivos, de agosto de 2005 a julho de 2006. As capturas foram realizadas por meio de armadilhas de interceptação e queda, distribuídas em oito sítios, sendo quatro em área de mata de galeria e quatro em área aberta, perfazendo... |
