Anthropogenic landscape decreases mosquito biodiversity and drives malaria vector proliferation in the Amazon rainforest

Chaves and collaborators [4] showed that an increase in the abundance of small patches of non-forest areas can intensify malaria transmission. Results of the current study provided strong statistical support for the mechanisms positively associated with anthropogenic modifi- cation in the Amazonian tropical rain forest landscape, changes in mosquito community, increased abundance of Ny. darlingi and intensification of malaria transmission. The socioeco- logical determinants were not tested, however, despite being a corollary to mosquito bites, Fig 6. Canonical correspondence analysis of mosquito assemblages and landscape structure classifications at each sampling unit. Open landscape (A) is represented by black circles, fragmented open land (B) is represented by red, fragmented forest (C) is represented by green, and forested (D) is represented by blue circles.
