Flora and Annual Distribution of Flowers and Fruits in the Ubajara National Par...
Silveira, Andréa Pereira; Menezes, Bruno Sousa de; Loiola, Maria Iracema Bezerra; Lima-Verde, Luiz Wilson; Zanina, Dalva Neta eAlthough the conservation of tropical biodiversity depends on protected areas, there is still a very large ‘gap’ of knowledge on the flora of Brazilian reserves, especially in the Northeast region of Brazil. Field and herbarium surveys of the phanerogamic flora of the Ubajara National Park, located on the Brazilian Northeast, were made and analyses on phenology and dispersal syndromes were performed. 418 taxa (...
Life history and population dynamics of a tree species in tropical semi-arid cl...
Silveira, Andréa Pereira; Martins, Fernando Roberto; Araújo, Francisca S.In semi-arid climates, plant population dynamics are strongly influenced by the amount and temporal distribution of rainfall. We monitored a population of the tree species Cordia oncocalyx (Boraginaceae) for 24 months in the dry thorny woodland of semi-arid northeastern Brazil, to investigate which life-history traits allow this tree to be locally dominant. We used horizontal life tables and a Lefkovitch matrix...

Woody flora in public school landscaping: managers’ perception about the choice...
Santos, Francisco Alves; Cordeiro, Alexsandra de Sousa; de Sousa, Maria Adriele dos Santos; Santana, Isabel Cristina Higino; Silveira, Andréa PereiraThe afforestation of urban spaces aims to mitigate harmful effects generated by the modification of natural environments, as well as esthetic goals. This action, sometimes, occurs in a disordered manner, which can cause disorders by the introduction of exotic species. Schools also promote forestry arrangements in the composition of the surrounding afforestation. In this context, we intende to understand the pro...
Representações do conceito de Ecologia: análise de livros didáticos e concepção...
Barbosa, Liduina Lima Pires; Silveira, Andréa PereiraResumo: A Ecologia é uma ciência que possui diferentes definições, sendo as mais utilizadas as de Haeckel e Krebs, contrastantes do ponto de vista temporal e conceitual. Por isso propomos: i) registrar as definições de Ecologia presentes nos livros didáticos utilizados na Universidade Estadual do Ceará, Faculdade de Educação de Itapipoca UECE/FACEDI e nas escolas do ensino básico de Itapipoca-Ceará e ii) acessa...
A natureza da ciência na sala de aula: conhecendo concepções e possibilidades n...
Santos, Francisco Alves; Santana, Isabel Cristina Higino; Silveira, Andréa PereiraResumo: Pensar o ensino de Ciências exige do professor múltiplas perspectivas de atuação que possibilite ao aluno compreender a Ciência em seus diversos aspectos sociais, culturais, tecnológicos, religiosos e políticos. Assim o objetivo deste estudo foi conhecer as concepções sobre a Natureza da Ciência (NdC) e seu uso no ensino de Ciências Naturais, especificamente Biologia e Química. O estudo de caráter quali...
Rural and school community in appreciating knowledge on medical plants
Carneiro, Marcílio Souza; Silveira, Andréa Pereira; Gomes, Vaneicia dos SantosIsolated communities in the urban environment still use medicinal plants, but such knowledge is not always passed on to new generations. In this scenario, we propose a study with students, teachers, and community residents from Córrego da Ema, Amontada, Ceará, Brazil, aiming to know the wisdom of medicinal plants in a small rural community in the Brazilian semi-arid region. We interviewed the medicinal plant co...
