Effect of land use change on Melolonthidae (Coleoptera: Scarabaeoidea) beetle communities in the deforestation arc of the Brazilian Amazon

Insect Conservation and Diversity, EarlyView.
Habitat transformation in Amazon due to agriculture expansion impairs Melolonthidae diversity. Assemblage response towards habitat transformation are group‐dependent. Although highly disturbed, Amazon arc of deforestation region dwells sensitive insect assemblages. Abstract Although the Amazon provides crucial goods and ecosystem services for humanity,

Parallel functional and stoichiometric trait shifts in South American and African forest communities with elevation [PDF]

, 2017
The Amazon and Congo basins are the two largest continuous blocks of tropical forest with a central role for global biogeochemical cycles and ecology. However, both biomes differ in structure and species richness and composition.

Behind the Myth: Land Sparing and Deforestation in Brazil

Journal of Agrarian Change, EarlyView.
ABSTRACT The land sparing model, that is, the idea that agricultural intensification fosters environmental protection, lacks empirical validation. In Brazil, sustainable intensification through the conversion of degraded pastures into agricultural areas became a promising and widespread solution to deforestation. We investigate the mismatch between the

Impacts of convection, chemistry, and forest clearing on biogenic volatile organic compounds over the Amazon

Nature Communications
The Amazon rainforest is the largest source of biogenic volatile organic compounds (BVOCs) to the atmosphere. To understand the distribution and chemistry of BVOCs, airborne and ground-based measurements of BVOCs are conducted over the Amazon rainforest ...
