Population structure and activity pattern of one species of Adenoma Steindachner, 1867 (Anura: Leptodactylidae) in northeastern Brazil

We analyzed the population structure and sexual size dimorphism of an Adenomera species occurring in the municipality of São Gonçalo do Amarante, from September 2010 to August 2011, using pitfall traps and active searches. We captured 116 individuals; 36 males, 23 females and 57 juveniles. Sexual size dimorphism was not observed. The smallest individuals were found in the middle of the rainy season, and the higher abundance of juveniles during this period may be related to recruitment. Females were captured in pitfall traps more often than males, while males were captured during active searches more often than females due to their calling behavior. We provide basic information regarding this Adenomera population, located in a region of severe environmental degradation, which may serve as a source of information for future studies of the area aiming to evaluate how the construction of industrial complexes affects anuran populations

Axanthism in Pithecopus gonzagai Andrade et al., 2020 (Anura: Phyllomedusidae)

The coloration pattern in wild animals is an important characteristic for survival as well as for intra and interspecific communication, being aberrant colorations rarely observed in vertebrates. Axanthism is the lack of yellow pigmentation, and considered an infrequent anomaly, for which cases have been described in amphibians. We describe herein a case in the frog Pithecopus gonzagai, a species characterized by predominantly arboreal habits and widely distributed in northeastern Brazil. This is the first report of an axanthic adult specimen of P. gonzagai, found in the municipality of Juazeiro do Norte, Ceará, Brazil.Asociación Herpetológica Argentin

APLICATIVOS MÓVEIS UTILIZADOS NO ENSINO DE BIOLOGIA: UMA REVISÃO SISTEMÁTICA DE LITERATURA

Aplicativos móveis educacionais podem contribuir na maneira de transmitir e receber informações. Assim, o objetivo desse artigo foi realizar uma revisão sistemática de literatura (RSL) a partir de estudos empíricos que abordaram o uso de aplicativos no ensino de biologia. Para isso, delimitaram-se questões primárias e secundárias de pesquisa, bases de dados para buscas, elaboração de string e dos critérios de inclusão e exclusão de trabalhos relacionados à temática. Nove trabalhos foram escolhidos, sendo 66,6% provenientes da região nordeste. Apenas um foi desenvolvido no ensino fundamental e os conteúdos mais abordados foram a citologia e a botânica. Evidencia-se que todos os aplicativos utilizados são compatíveis com sistema Android e a coleta de dados pelos autores foi realizada sobretudo com questionários. O benefício do uso de aplicativos mais citados pelos trabalhos foi a promoção do protagonismo do estudante, enquanto a ausência de conexão com a internet foi a adversidade mais relatada

Anuran diversity indicates that Caatinga relictual Neotropical forests are more related to the Atlantic Forest than to the Amazon

The relationships among the morphoclimatic domains of South America have been a major biogeographical issue of recent years. Palynological, geological and phytogeographical data suggest that the Amazon Forest and the Atlantic Forest were connected during part of the Tertiary and Quaternary periods. This study uses amphibians as model organisms to investigate whether relict northeastern forests are a transition between the Amazon Forest and the Atlantic Forest. We compiled matrices of species composition for four different phytogeographic formations and “Brejos de Altitude,” and analyzed them using clustering methods and Cladistic Analysis of Distributions and Endemism. Our results indicate that the anurofauna of these northeastern forest relicts is most similar in composition to the areas of the Atlantic Forest included in this study, and most dissimilar to the Amazon Forest, which leads us to affirm that events of biotic exchange were more frequent within the Atlantic Forest areas

First records of Chthonerpeton arii Cascon and Lima-Verde, 1994 (Amphibia: Gymnophiona: Typhlonectidae) out of the type locality

Chthonerpeton arii was described from a large series of specimens from Limoeiro do Norte municipality, state of Ceará, Brazil. Here we provide the first records of the species out of the type locality, in the state of Bahia, and in its border with the state of Pernambuco, Brazil. We also provide color photographs of a preserved specimen

Crenças associadas a serpentes no estado do Ceará, Nordeste do Brasil

Snakes, since the dawn of humanity, makepart of an amount of legendary histories and mythes of the whole world because of their true capability in increasing thepopular imaginary. In Brazil, in almost all areas, there is an abundant folklore about these animals. An ethnographic surveyabout the beliefs and the respective scientific considerations involving snakes in Ceará State, northeastern Brazil, werecarried out between 2008 and 2010. Semi-structured interviews were carried out with selected ‘local experts’ in themunicipalities of Aratuba, Pacoti and Mulungu (mountain region); Itapajé, Irauçuba and Tururu (semi-arid region) and SãoGonçalo do Amarante and Caucaia (coastal area). In the study areas, there is a local differentiation between ‘snakes withand without venom’, although even the majority of snakes considered venomous by the locals are not lethal to humans.The interviewees indicated a preference in the use of snake anti-venum in case of snake bites, however, they alsoconsidered that home remedies were effective. For certain specific snakes, we described the folklore characterized byassimilation of morphological, physiological and ecological features, the majority of which are not corroborated by thezoological literature. This is probably because the sense of fear makes it difficult to promote folklore in a manner that ismore consistent with scientific knowledge. The conflicting relationship between humans and snakes has led to a commonlaw justification for the indiscriminate hunting of these animals causing serious environmental and health problems thatcan only be addressed through public policies directed towards environmental education, and the prevention and treatmentof snakebites.As serpentes, desde os primórdios da humanidade, são alocadas em relatos míticos e lendários de diversasetnias e regiões de todo o mundo devido à sua capacidade histórica de despertar o imaginário popular. No Brasil, empraticamente todas as regiões, existe uma grande riqueza de crenças envolvendo esses animais. A fim de realizar umlevantamento etnográfico sobre as crenças e suas respectivas inferências científicas envolvendo ofídios no estado do Ceará,Nordeste do Brasil, foram realizadas, entre os anos de 2008 e 2010, entrevistas semiestruturadas com “especialistaslocais” selecionados nos municípios de Aratuba, Pacoti e Mulungu (área serrana); Itapajé, Irauçuba e Tururu (área sertaneja)e o litoral de São Gonçalo do Amarante e Caucaia (área litorânea). Nas áreas abordadas, há uma diferenciação entre “cobrascom ou sem veneno”, sendo que a maioria das serpentes consideradas peçonhentas pelos entrevistados não possuempotencial venômico letal ao ser humano. Os entrevistados afirmam a prioridade de uso do soro antiofídico em caso deacidentes, porém eles consideram outros procedimentos caseiros como eficazes. Para determinadas espécies de serpentes,foram levantadas crenças constituídas por assimilações de caracteres morfológicos, fisiológicos e ecológicos, a maioria dasquais não corrobora a literatura zoológica. Isso acontece provavelmente porque o sentimento de medo impede umaaproximação que pudesse promover um conhecimento popular que corroborasse de maneira mais consistente o conhecimentocientífico. A relação conflituosa entre humanos e serpentes leva a uma justificativa leiga para o abate indiscriminado dessesanimais, causando problemas ambientais e de saúde pública graves, que devem ser solucionados principalmente através depolíticas públicas de educação ambiental, prevenção e tratamento de acidentes ofídicos
