Sexual dimorphism, deformations, and epibionts of Phrynops tuberosus (Testudine...
Rodrigues, João Fabrício Mota; Silva, José Roberto FeitosaStudies focusing on the natural history of species are essential for developing effective conservation measures and evaluating ecological hypotheses. To this end, we describe natural history data of the Cotinga River toadhead turtle, Phrynops tuberosus, in the Banabuiú River in Ceará, Brazil, and evaluated sexual dimorphism, epibionts, and mutilation effects. We hand-captured 134 individuals by snorkeling, over...
Formal education, previous interaction and perception influence the attitudes o...
Pinheiro, Luan Tavares; Rodrigues, João Fabrício Mota; Nojosa, Diva Maria BorgesThe attitudes and perceptions of people toward animals are influenced by sociodemographic factors, such as formal education and gender, and by personal experience. Understanding these interactions is critical for the establishment of conservation strategies for animals that have conflictual relationships with humans, such as snakes. Our study aims to explain how perceptions and the human fear of snakes vary and...
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...
Topographic anatomy and sexual dimorphism of Bothrops erythromelas AMARAL, 1923...
Gondim, Patrícia de Menezes; Rodrigues, João Fabrício Mota; Leite, Maria Juliana Borges; Nojosa, Diva Maria Borgesinformation on the internal anatomy of brazilian serpents is scarce. Bothrops erythromelas AMArAl, 1923, native to the northeast brazilian ecoregion called Caatinga, is also poorly known with regard to its biology. this study aimed to investigate the topographic anatomy and sexual dimorphism in B. erythromelas. the position of internal organs was characterized by the numbers of the ventral scales where they beg...
Does climate influence assemblages of anurans and lizards in a coastal area of ...
Rodrigues, João Fabrício Mota; Leite, Maria Juliana Borges; Nojosa, Diva Maria BorgesEnvironmental factors influence diverse assemblage features such as species abundances, richness, and nestedness. Amphibians and reptiles play important roles in terrestrial ecosystems, but there is still a lack of information about the assemblages of these animals in many regions. In this study, we aimed to understand how environmental factors influence the anurans and lizards assemblages from São Gonçalo do A...
Como os cágados sobrevivem e se reproduzem na caatinga? Aspectos da história de...
Rodrigues, João Fabrício MotaThe life history theory studies the characteristics combinations that maximize the organisms reproduction and survival in the environment where they live. The species use the habitat in a diverse way and this use depends on the environmental conditions in the available habitats. Phrynops tuberosus, a freshwater turtle found in the north-northeastern regions of Brazil, is the animal-model chosen for the life his...
