Developmental aspects of the direct-developing frog Adelophryne maranguapensis
Lima, Ana V. P. de; Reis, Alice H.; Amado, Nathalia G.; Lima, Daniel Cassiano; Nojosa, Diva M. BorgesDirect development in amphibians is characterized by the loss of aquatic breeding. The anuran Adelophryne maranguapensis is one example of a species with direct development, and it is endemic to the state of Ceara, Brazil. Detailed morphological features of A. maranguapensis embryos and the stages of sequential development have not been described before. Here, we analyzed all available genetic sequence tags in ...
Reproductive biology of direct developing and threatened frog Adelophryne maran...
Lima, Daniel Cassiano; Lima, Ana V. P; Fortunato, Márcia E. M; Sousa, Tiago A. de; Castro, Déborah P. de; Nojosa, Diva M. Borges; Cechin, Sonia ZAnurans with direct development are among the most difficult species for conducting studies concerning ecology and natural history. This paper provides information on the reproduction of Adelophryne maranguapensis, a threatened species endemic to Serra de Maranguape, an Atlantic Forest relict surrounded by dry Caatinga phytophysiognomies. Our objectives were to identify the reproductive periods, verify any pref...
A new species of Hepatozoon Miller, 1908 (Apicomplexa: Adelerina) from the snak...
Nojosa, Diva M. Borges; Leite, M. Juliana Borges; Maia, João P.; Silva, Djan Zanchi; Braga, Roberta da Rocha; Harris, D. JamesBased on both unique morphological characteristics of the gamont, distinct changes caused to the host erythrocyte and analysis of partial 18S rRNA gene sequences, a new parasite of the genus Hepatozoon Miller, 1908 is described from the snake Philodryas nattereri Steindachner (Squamata: Dipsadidae) in northeastern Brazil. The new species, Hepatozoon musa n. sp., is characterized by large and curved mature gamon...
Venomics and antivenomics of Bothrops erythromelas from five geographic populat...
Jorge, Roberta Jeane B.; Monteiro, Helena S. A.; Machado, Larissa Gonçalves; Guarnieri, Míriam C.; Ximenes, Rafael M.; Nojosa, Diva M. BorgesThe Caatinga lancehead, Bothrops erythromelas, is a medically relevant species, responsible for most of the snakebite accidents in most parts of its distribution range in northeastern Brazil. The spectrum and geographic variability of its venom toxins were investigated applying a venomics approach to venom pools from five geographic areas within the Caatinga ecoregion. Despite its wide habitat, populations of B...
