Biodiversity, threats and conservation challenges in the Cerrado of Amapá, an A...
Mustin, Karen; Carvalho, William Douglas de; Hilário, Renato Richard; Costa-Neto, Salustiano Vilar da; Silva, Cláudia Regina; Vasconcelos, Ivan M.An Amazonian savanna in northern Brazil known as the Cerrado of Amapá is under imminent threat from poor land-use planning, the expansion of large-scale agriculture and other anthropogenic pressures. These savannas house a rich and unique flora and fauna, including endemic plants and animals. However, the area remains under-sampled for most taxa, and better sampling may uncover new species. We estimate that onl...
The role of Pleistocene climate change in the genetic variability, distribution...
Silva, Cláudia Regina; Ribas, Camila Cherem; Silva, Maria Nazareth Ferreira da; Leite, Rafael N.; Catzeflis, François M.; Rogers, Duke S.The spiny rats, genus Proechimys, have the highest species richness within the Echimyidae family, as well as species with high genetic variability. The genus distribution includes tropical South America and Central America south to Honduras. In this study, we evaluate the phylogeographic histories of Proechimys guyannensis and P. cuvieri using cytochrome b, in a densely sampled area in northeastern Amazon where...
Biogeography of squirrel monkeys (genus Saimiri): South-central Amazon origin a...
Lynch Alfaro, Jessica W.; Boubli, Jean Philippe; Paim, Fernanda Pozzan; Ribas, Camila Cherem; Silva, Maria Nazareth Fda; Messias, Mariluce RezendeThe squirrel monkey, Saimiri, is a pan-Amazonian Pleistocene radiation. We use statistical phylogeographic methods to create a mitochondrial DNA-based timetree for 118 squirrel monkey samples across 68 localities spanning all Amazonian centers of endemism, with the aim of better understanding (1) the effects of rivers as barriers to dispersal and distribution; (2) the area of origin for modern Saimiri; (3) whet...
Concepções de saúde na educação em enfermagem em escolas de graduação do Brasil...
Silva, Cláudia Regina; Costa, Maria ArmindaEste artigo representa um recorte de pesquisa de doutorado a respeito das concepções de saúde, presentes em escolas de graduação em enfermagem do Brasil e de Portugal. O objetivo foi compreender como as concepções de saúde estão explícitas nos documentos dos cursos de graduação e de que forma se expressam nos discursos dos professores e estudantes de enfermagem. Para tanto, utilizou-se análise de conteúdo temát...
