O presente estudo teve como objetivo auxiliar professores a desenvolverem videoaulas como organizadores prévios no processo de ensino de Ciências da Natureza. A proposta fundamenta-se teoricamente na Teoria da Aprendizagem significativa de David Ausubel e na contribuição das Tecnologias da Informação e Comunicação na sala de aula. Para tal, foi des...

Conservation status of Agalychnis granulosa

In 2005, the Species Survival Commission (SSC) of the International Union for Conservation of Nature (IUCN) and Conservation International (CI) convened the Amphibian Conservation Summit to design a global plan of action, the Amphibian Conservation Action Plan (ACAP), to address the decline of amphibian populations worldwide. The IUCN SSC Amphibian...

Population declines and species extinction can be abated through the establishment of effective conservation policies. Actions and policies towards biodiversity conservation must be well planned and priorities must be set. Besides the widely recognized principles of systematic conservation planning, it is also important to consider species attribut...

Aim Scenarios of species extinction have been created to assess how the loss of species affects the loss of evolutionary history (EH). However, estimates of the rate of EH loss at regional scales are scarce. Here we provide the first estimate of projected EH loss of New World anurans encompassing both continental and regional scales. Location New W...

Species distribution patterns result from the combination of multiple factors acting over different spatial and temporal scales. We analyze the distribution patterns of anuran amphibians within the Cerrado domain of South America in a historical framework. First, we provide an updated list of species based on extensive research in zoological collec...

Brazil has a fundamental role in amphibian conservation, harboring the highest amphibian species richness in the world and a large number of endemics. Here, we present an overview of the Brazilian Amphibian Conser-vation Action Plan (BACAP), which is still being developed by Brazilian herpetologists. Basic research ¢ particularly species inventorie...

Assessing Biodiversity Declines Understanding human impact on biodiversity depends on sound quantitative projection. Pereira et al. (p. 1496 , published online 26 October) review quantitative scenarios that have been developed for four main areas of concern: species extinctions, species abundances and community structure, habitat loss and degradati...

Brazil is the world leader in amphibian diversity, with 765 species, most of which have been described in the last 40 years. The Brazilian Official List of Threatened Species and the results of a workshop for the Global Amphibian Assessment indicate that 26 species are threatened. The majority of these occur in the Atlantic Forest, one of the world...

Population declines have previously been reported for at least 31 amphibian species in Brazil, in the families Leptodactylidae (19), Hylidae (7), Centrolenidae (2), Dendrobatidae (2) and Bufonidae (1). In five Brazilian museum collections, we found no entries of new records dating back to at least 15 yr ago for 13 of these species. We suggest that...

A new species of the Physalaemus signifer group from the Atlantic Rain Forest of the state of Bahia is described and illustrated. It is characterized by a well-developed vocal sac, second finger with the same size or longer than fourth, finely rugose dorsal skin, and distinct structure of advertisement call, composed of densely aggregated pulses. I...

RESUMO: Apresenta-se a descrição de duas novas espécies do complexo de Hyla albosignata, provenientes de fragmentos de Mata Atlântica do sul do Estado da Bahia e do nordeste do Estado de Minas Gerais. das outras espécies deste complexo, que ocupam riachos de montanha, as espécies descritas ocupam também ambientes associados a riachos de baixada. Su...

INTRODUÇÃO O conhecimento sobre a composição dos grupos de vertebrados de uma área é fator de importância primordial em projetos para a sua conservação. Assim, a identificação das espécies de anfíbios e o estudo de suas particularidades ecológicas revelam-se decisivos para o sucesso das ações que buscam conservar a biodiversidade (Heyer et al., 199...

Corredores ecológicos têm sido recentemente considerados como paradigma para assegurar a conservação da diversidade biológica original em áreas fragmentadas. A adoção de um modelo conservacionista incrementando o grau de conectividade entre reservas e remanescentes florestais atualmente isolados visa estimular a ocorrência de fluxo gênico entre esp...
