| The ant diversity observed in stomach contents of fossorial reptiles was compared to the subterranean ant richness collected using traditional and modern techniques of ant collections. We analyzed the alimentary tract of 64 specimens of amphisbaenians (4 Amphisbaena alba, 10 A. fuliginosa, 25 A. vermicularis, and 25 Leposternon infraorbitale) collected during the fauna rescue for the construction of Serra da Mesa hydroelectric dam in the Tocantins River (from 1992 to 1997), in Minaçu County, Goiás, Brazil. We found only five ant species present in the stomach contents, all belonging to the army ants subfamily Ecitoninae. In contrast, the traditional techniques for subterranean ants' collection are far more efficient than the exam of fossorial reptile's... |

| Visceral anatomy of amphisbaenids Amphisbaena vermicularis Wagler, 1824; Anops kingii Bell, 1833; Aulura anomala Barbour, 1914; Bronia bedai Vanzolini, 1991; Cercolophia cuiabana Strüssmann & Carvalho, 2001, and Leposternon microcephalum Wagler, 1824 were comparatively described and the size and the position of the organs in the pleuroperitoneal cavity was established in relation to the ventral scutellation. The main results were: the right lung presents different degrees of size reduction compared to the left lung, being conspicuous only in A. anomala, and L. microcephalum; the limit between small and large intestines is clear due to the presence of a caecum; the right lobe of the liver is larger than the left one, but its length varies within the... |

| ABSTRACT Studies on the thermal biology of fossorial reptiles that examine the relationship between the body temperature and thermal environment are needed to determine the extent of their thermoregulation abilities. This study assessed the thermal biology of Amphisbaena munoai Klappenbach, 1969 in the rocky fields of the Rio Grande do Sul and in the laboratory. The body temperature of most individuals was between 24 and 30 °C, both in the field (n = 81) and laboratory (n = 19). More individuals were caught in winter (n = 55) and spring (n = 60) than in summer (n = 25) and fall (n = 45), and in spring, individuals showed similar nocturnal and diurnal activities. In the laboratory, we found individuals with body temperatures up to 5 °C higher than the... |

| ABSTRACT The increasing urbanization of the Amazonian biome has promoted the creation of several forest fragments surrounded by an urban matrix, but the relationship of animal assemblages to the urban environment, especially in forest fragments, is poorly known. Here we aimed to 1) determine the composition of the squamate fauna of the largest urban forest fragment from central Amazonia, in the Brazilian city of Manaus, and 2) evaluate the influence of environmental parameters on assemblage diversity. We sampled 10 standardized riparian plots through visual search in six surveys between 2008/09 and 2015, totaling 360 observer-hours. We found 15 species of lacertoids (lizards and amphisbaenians) and seven species of snakes through active search. After... |
