Anatomia visceral comparada de seis espécies de Amphisbaenidae (Squamata: Amphisbaenia) Rev. Bras. Zool.
Navega-Gonçalves,Maria Eliana C..
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...

Subterranean ants (Hymenoptera, Formicidae) as prey of fossorial reptiles (Reptilia, Squamata: Amphisbaenidae) in Central Brazil Pap. Avulsos de Zool. (São Paulo)
Esteves,Flávia de Araújo; Brandão,Carlos Roberto Ferreira; Viegas,Karen.
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...

Thermal biology of Amphisbaena munoai (Squamata: Amphisbaenidae) Rev. Bras. Zool.
Matias,Nathalia Rocha; Verrastro,Laura.
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...

Water dispersal of Amphisbaena alba and Amphisbaena amazonica (Squamata: Amphisbaenia: Amphisbaenidae) in Brazilian Amazonia Rev. Bras. Zool.
Maschio,Gleomar F.; Prudente,Ana L. da C.; Mott,Tami.
Information on the use of aquatic environments by two species of amphisbaenids (Amphisbaena amazonica Vanzolini, 1951 and Amphisbaena alba Linnaeus, 1758) are presented. These findings suggest that aquatic environments are not a barrier to these animals, until now considered as strictly fossorial. New studies on amphisbaenians in natural conditions are needed in order to better understand which species may use water environment during dispersal events and the frequency of this behavior in the group.
