Molecular screening of Plasmodium (Haemosporidia: Plasmodiidae) parasites from ...
Harris, D. James; Santos, Joana L.; Borges-Nojosa, Diva Maria; Castro, Déborah Praciano deHemosporidians are a monophyletic group of protozoan parasites infecting all terrestrial vertebrate orders. Although Plasmodium is the most studied genus within the Haemosporidia, this research effort is heavily biased toward mammal and bird hosts. We screened 205 specimens of at least 18 reptile species from Brazil using a partial mitochondrial cytochrome b gene marker. Positive samples were sequenced and incl...
Single large or several small?: the influence of prey size on feeding performan...
Pereira, Sara Catunda; Rodrigues, João Fabrício Mota; Borges-Nojosa, Diva MariaThis study aimed at evaluating the energetic return and feeding time on Philodryas nattererikept in captivity. Snakes were fed biweekly for 60 days (four feeding trials), in two different feeding treatments (single and multiple prey items). The energetic return revealed no significant difference between the feeding treatments; however, we found a negative relationship between snake size and prey handling time d...
FIRST RECORD OF AN AMNIOTIC EGG FROM THE ROMUALDO FORMATION (LOWER CRETACEOUS, ...

No. of bitstreams: 0 Previous issue date: 2020-07-01; Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES); Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq); Fossil amniotic eggs have great informative potential, especially regarding reproductive and evolutionary aspects of vertebrates. However, there are only few intact ...
First record of tail bifurcation in Lygodactylus klugei (Smith, Martin & Swain,...
Lima Ramos, Antônio Rafael; Oliveira, John Allyson Andrade; Silva, Margarida Maria Xavier da; Tavares, Robson Victor; Borges-Nojosa, Diva MariaThe process of caudal regeneration in lizards does not always occur perfectly, which can cause some abnormalities, such as the appearance of warped or supernumerary tails. Here we report the first cases of tail bifurcation in the Dwarf Gecko, Lygodactylus klugei, and observations about the caudal adhesive pads in individuals with bifurcated tails. Our observations represent a new case of caudal bifurcation for ...
Interdisciplinaridade em tecnologia educacional e educação ambiental
Borges-Nojosa, Diva Maria; Lima, Isaias Batista; Ribeiro, Júlio WilsonA época atual é marcada por um agressivo processo de desenvolvimento tecnológico. Este invadiu todos os espaços da vida social, econômica, política e cultural, assumindo um caráter mundial, de tal modo que assumimos numa escala de relações a feição de uma comunidade planetária conectada on-line e virtualmente. Tal comunidade incorpora práticas de relacionamento, até então nunca imaginadas pelos pensadores da mo...
Assessing the influence of geographic distance in parasite communities of an ex...
Bezerra, Castiele Holanda; Pinheiro, Luan Tavares; Melo, Gabriela Cavalcante De; Zanchi-Silva, Djan; Queiroz, Murilo De Souza [UNESP]Made available in DSpace on 2018-12-11T17:26:54Z (GMT). No. of bitstreams: 0 Previous issue date: 2016-01-01; The decay of similarity between biological communities with increasing geographical distance is a well-established pattern in ecology, but there are more complex factors acting on host population connections that influence this association for parasite communities, such as parasites' colonization abilit...
Alterações morfológicas de pele de camundongos inoculados com o veneno total da...
Vasconcelos, Rebeca Horn; Silveira, João Alison de Moraes; Morais, Glayciane Bezerra de; Oliveira Neto, Joselito deSnake venoms are composed of complex active substances, most of them of protein nature, causing various effects on humans and domestic animals and can lead to death. Philodryas nattereri is a native snake Ceara region, found throughout the state. This study aimed to know the morphological and physiological changes in mouse skin after inoculation with the total venom this serpente. The animals were divided into ...
Crotalus durissus cascavella venom toxicity to mammalian cells
Araújo, Lucelina da Silva; Rocha, Danilo Damasceno; Viana, Daniel Araújo; Silveira, João Alison de Moraes; Vasconcelos-Filho, Francisco Sérgio LopesSnakes from the genus Crotalus gained significant space in the scientific field since the development of researches with their venom involving cytotoxic activity. Crotalus durissus cascavella is the only subspecies recorded of the Caatinga biome of Northeastern Brazil and it’s noticed a lack of studies on its venom properties. The present study evaluated the crude venom of C. d. cascavella for its cytotoxic act...
