Endoparasites in domestic animals surrounding an Atlantic Forest remnant, in São Paulo State, Brazil

Abstract Morro do Diabo State Park (MDSP) is a significant remnant of the Atlantic Rain Forest in Brazil and is surrounded by rural properties. In that area, wild and domestic animals and humans are in close contact, which facilitates the two-way flow of infectious diseases among them. We assessed endopa...

Ash content, carbon and C/N ratio in paricá in function of NPK fertilization

An. acad. bras. ciênc; 90 (1), 2018
ABSTRACT Fertilization in areas of forest plantations is needed to supplement plants´ nutritional needs until harvest. An experiment was performed to check the influence of fertilization on levels of ash, carbon and C/N relation in Schizolobium amazonicum. Soil liming was performed and fertilization occ...

Biodiversity of Coreoidea and Pentatomidae (Heteroptera) from Atlantic forest protected areas. Insights into their conservation

An. acad. bras. ciênc; 90 (1), 2018
ABSTRACT Although the majority of threatened species are likely to be tropical insects, knowledge of the diversity, ecological role and impact of insect biodiversity loss on ecosystem processes is very limited. Specimens belonging to four families of Heteroptera: Pentatomidae, Coreidae, Alydidae and Rhop...

Bird diversity along a gradient of fragmented habitats of the Cerrado

An. acad. bras. ciênc; 90 (1), 2018
ABSTRACT Understanding the factors that affect biodiversity is of central interest to ecology, and essential to species conservation and ecosystems management. We sampled bird communities in 17 forest fragments in the Cerrado biome, the Central-West region of Brazil. We aimed to know the communities stru...

Ecological characterisation and infection of Anophelines (Diptera: Culicidae) of the Atlantic Forest in the southeast of Brazil over a 10 year period: has the behaviour of the autochthonous malaria vector changed?

Mem. Inst. Oswaldo Cruz; 113 (2), 2018
BACKGROUND In southeastern Brazil, autochthonous cases of malaria can be found near Atlantic Forest fragments. Because the transmission cycle has not been completely clarified, the behaviour of the possible vectors in those regions must be observed. A study concerning the entomological aspects and natura...

Estudo da dinâmica de transmissão de malária autóctone de Mata Atlântica: análise da variação na acrodendrofilia de Anopheles cruzii (Diptera: Culicidae) e desenvolvimento de modelo matemático para a transmissão zoonótica

A Malária autóctone de Mata Atlântica é caracterizada por baixa incidência de casos com pouca ou nenhuma manifestação clínica e baixa parasitemia, tendo como principal agente etiológico o Plasmodium vivax (ou plasmódios muito semelhantes a este). O principal mosquito envolvido na transmissão ...

A method for estimating the deforestation timeline in rural settlements in a scenario of malaria transmission in frontier expansion in the Amazon Region

Mem. Inst. Oswaldo Cruz; 113 (9), 2018
The Malaria Frontier Hypothesis (MFH) is the current model for predicting malaria emergence in the Brazilian Amazon. It has two important dimensions, 'settlement time' and 'malaria incidence', and its prediction are: malaria incidence peaks five years after the initiation of human settlement and declines...

X-linked spinal and bulbar muscular atrophy (Kennedy's disease): the first case described in the Brazilian Amazon

Einstein (Säo Paulo); 16 (2), 2018
ABSTRACT The X-linked spinal and bulbar muscular atrophy (Kennedy's disease) is a rare X-linked, recessive, lower motor neuron disease, characterized by weakness, atrophy, and fasciculations of the appendicular and bulbar muscle. The disease is caused by an expansion of the CAG repetition in the androgen...
