Galling insects on neotropical species of Baccharis (Asteraceae)
TLDR
The most diverse gall communities were on Baccharis species that inhabit harsh environments, such as B. concinna in... and the most numerous galling taxa were, in decreasing order, Cecidomyiidae (Diptera), Lepidoptera (several Gelechiidae), Psyl- lidae (Homoptera), and Tephritidae (diptera). Expand
Edge effect and species–area relationships in the gall-forming insect fauna of natural forest patches in the Brazilian Pantanal
TLDR
The results suggest that the number of galling insects per individual plant is not affected by the size of the patch, and the natural forest patches found in this region seem well suited for long-term studies addressing species–area relationships. Expand
Unexpected High Diversity of Galling Insects in the Amazonian Upper Canopy: The Savanna Out There
TLDR
The results also support the “harsh environment hypothesis”, and unveil the Amazonian upper canopy as similar to Mediterranean vegetation habitats, hygrothermically stressed environments with leaf temperature at lethal limits and high levels of leaf sclerophylly. Expand
Diversity of galling insects in Styrax pohlii (Styracaceae): edge effect and use as bioindicators.
TLDR
It is concluded that galling insects associated with Styrax pohlii (Styracaceae) host plant could be employed as biological indicators because of their host-specificity, they are sensitive to changes in plant quality, and they present dissimilar and specific responses to local variation in habitat conditions. Expand
Hiding from defenders : Localized chemical modification on the leaves of an amazonian ant-plant induced by a gall-making insect (Diptera: Cecidomyiidae)
TLDR
Results indicate that insect gall tissues on this myrmecophyte probably do not possess compounds which can be detected by the ants, and a local change seems to be very helpful to gall-forming insects because they are protected from, and by, ants which deter herbivores. Expand
RICHNESS AND ABUNDANCE OF GALL-FORMING INSECTS IN THE MAMIRAUA VARZEA, A FLOODED AMAZONIAN FOREST
TLDR
Contrary to the predictions, a high richness and abundance of galling insects in the varzea, a non-scleromorphic vegetation that grow in fertile soils is found. Expand
Calodium hepaticum: Household Clustering Transmission and the Finding of a Source of Human Spurious Infection in a Community of the Amazon Region
TLDR
The mechanism of transmission based on the ingestion of liver is important for the dynamics of transmission of C. hepaticum in humans and a high rate of incidence in household clusters related to game liver alimentary habits is described. Expand
Comparison of the performance of two spontaneous sedimentation techniques for the diagnosis of human intestinal parasites in the absence of a gold standard.
TLDR
High repeatability of both tests was found for the detection of intestinal parasites, except for Blastocystis spp. Expand
Anthropic effects on sand fly (Diptera: Psychodidae) abundance and diversity in an Amazonian rural settlement, Brazil.
TLDR
The results show that changes in the human occupancy and vegetation management in rural settlements may affect the population dynamics and distribution of sand fly species, thereby affecting the local transmission of cutaneous leishmaniases. Expand
