Many parts of the Brazilian Amazon are neglected in ecological research, for several reasons, according to an article published in the journal Current Biology. Authored by Joice Ferreira of the Federal University of Pará (UFP) and colleagues from many countries who also belong to the Synergize Consortium, the article identifies the areas missing from ecological research and the factors that have determined these gaps, pinpointing opportunities for the planning of new investments in [...]

Researchers at São Paulo State University (UNESP) in Brazil have developed a strategy for removing glyphosate, one of the world’s most frequently used herbicides, from water. Inspired by the concept of the circular economy, the technique is based on sugarcane bagasse, a waste material produced by sugar and ethanol plants. “Isolated and chemically functionalized sugarcane bagasse fibers can be used as adsorbent material. Glyphosate adheres to its surface and is removed as a [...]

A research project supported by FAPESP shows that the construction of new hydroelectric power plants in Brazil’s South region could have an impact on more than 30% of the habitat of Phrynops williamsi, the Williams’ side-necked turtle. The species occurs only in areas of Atlantic Rainforest and Pampa (the grassland biome adjacent to Brazil’s border with Uruguay and Argentina), and is classed as “Vulnerable” (facing a high risk of extinction) by the International [...]

A type of soil called terra preta da Amazônia, or Amazon dark earth (ADE), promotes faster growth of trees and enhances their development in qualitative terms, according to an article published in the journal Frontiers in Soil Science. The findings reported in the article resulted from studies supported by FAPESP (projects 20/08927-0, 18/19000-4 and 14/50320-4 ) under the aegis of its Biodiversity, Characterization, Conservation, Restoration and Sustainable Use Program ( BIOTA [...]

Researchers at the University of São Paulo (USP) in Brazil have developed a portable sensor made of simple materials to detect heavy metals in sweat, which is easily sampled. Heavy metals such as lead and cadmium are present in batteries, cosmetics, food and other things that are part of everyday life. They are toxic when they accumulate in the human organism, potentially causing several health problems, but detecting them in body fluids requires expensive equipment and a controlled [...]

According to a Brazilian study, active fire occurrences between 2003 and 2020 in the entire Amazon region were associated more with agricultural burning and deforestation rather than extreme scarcity of water. A new study has revealed that most of the burning of vegetation in the Amazon rainforest is to make room for pasture lands and other uses rather than because of drought. The Amazon is home to the world/’s largest rainforest and river system, and the most biologically diverse [...]

More than 70% of plant species that produce flowers depend on birds to disperse their seeds. Birds feed on fruit from a wide array of different plants, and bird-plant interactions configure a welter of complex networks. A study conducted at the University of São Paulo’s Institute of Biosciences (IB-USP) in Brazil shows that the evolutionary stability of each bird species depends on the position it occupies in these networks, increasing in step with the number and centrality of [...]
