Variations in water use by a mature mangrove of Avicennia germinans, French Guiana [PDF]

, 2009
In the tropical intertidal zones, little is known on water uptake by mangroves. Transpiration rates are generally measured at leaf level, but few studies exist on water use at tree or stand levels.

Ecological and functional effects of habitat conversion and seasons on fruit‐feeding butterfly assemblages in tropical dry forests Efeitos ecológicos e funcionais da conversão do habitat e da sazonalidade sobre assembleias de borboletas frugívoras em florestas tropicais secas

Ecological Entomology, EarlyView.
Land‐use change and seasonality shape the taxonomic, functional and phylogenetic diversity of fruit‐feeding butterflies in tropical dry forests. Pastures reduce phylogenetic diversity and increase wing fluctuating asymmetry, while taxonomic and functional diversity is greater in the wet season than in the dry season.

Influence of drainage status on soil and water chemistry, litter decomposition and soil respiration in central Amazonian forests on sandy soils [PDF]

, 2011
Central Amazonian rainforest landscape supports a mosaic of tall terra firme rainforest and ecotone campinarana, riparian and campina forests, reflecting topography-induced variations in soil, nutrient and drainage conditions.

State Integration and Violence at the Margins: The Logic of Police Raids in Rio de Janeiro's Favelas

The Howard Journal of Crime and Justice, EarlyView.
ABSTRACT This paper investigates police raids in Rio de Janeiro's favelas through a property rights framework, exploring their organisational structure, motivations and implications. Using data from police reports, academic studies, NGOs and news sources, it examines why and how the state intervenes in these contested spaces.

Yellow Fever Virus in Mosquitoes from Rainforest Bordering Manaus, Brazil, 2022

Emerging Infectious Diseases
We detected yellow fever virus in Haemagogus mosquitoes collected in 2022 in an Amazon rainforest bordering Manaus, Brazil. The viral genome sequence occupied a basal position within the South American I genotype 1E lineage.

Critical tipping points in dung beetle communities: Implications for conservation in the Atlantic Forest biome

Insect Conservation and Diversity, EarlyView.
Minor land‐use changes consistently lead to abrupt biodiversity shifts across all diversity dimensions, favoring generalist dung beetle species while excluding sensitive specialists. These shifts are observed at lower environmental change rates than previously considered, with significant changes apparent after just 25% habitat loss.

Post-drought decline of the Amazon carbon sink [PDF]

, 2018
Amazon forests have experienced frequent and severe droughts in the past two decades. However, little is known about the large-scale legacy of droughts on carbon stocks and dynamics of forests.

Impacts of land use change on diaspore‐dispersing ant assemblages in southwestern Amazonia

Insect Conservation and Diversity, EarlyView.
Land use changes shift ant assemblages, more intensive land uses are dominated by generalist and open habitat specialist species engaging in group foraging. The diaspore removal rates cannot differ, but the quality of dispersal was lower in disturbed habitats.
