The presence of Indigenous communities and traditional river dwellers in extractive reserves located in Legal Amazonia is not a threat to birds and mammals considered subsistence poaching targets, according to a study reported in the journal Biological Conservation Legal Amazonia is an area of more than 5 million square kilometers comprising the Brazilian states of Acre, Amapá, Amazonas, Maranhão, Mato Grosso, Pará, Rondônia, Roraima, and Tocantins. It was created [...]

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 [...]

The consequences of climate change in the Caatinga, the semi-arid shrubland and thorn forest biome in Brazil’s Northeast region, will include species loss, substitution of rare plants by more generalist vegetation, biotic homogenization (in which previously distinct plant communities become progressively more similar), increasing aridity, and even desertification in some areas.  These are some of the findings of a study reported in the Journal of Ecology by [...]

As global temperatures continue to reach all-time highs and discussions intensify about ways to mitigate the adverse effects of climate change, researchers at the University of São Paulo’s Luiz de Queiroz College of Agriculture (ESALQ-USP) in Brazil have reported the results of a scientific study showing that if all the country’s active legal mining sites continue to operate in the coming decades, emissions will total an estimated 2.55 gigatonnes of equivalent carbon dioxide [...]

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 portion of Amazonian lowland rainforest – areas critical to absorbing carbon dioxide and buffering climate change – may morph over time into dry, grassy savannas, according to a Rutgers-led study. The report, published in the scientific journal Proceedings of the National Academy of Sciences, described a new understanding of how alternating flooding in the wet season and drought in the dry season, called double-stress, can limit forest establishment and favor [...]

Brazilian researchers combined environmental physical, social and economic indicators to create an index that measures a region’s vulnerability and used it to analyze the basins of the Parnaíba River and São Francisco River in the Northeast of Brazil. The index is named SEVI (for Socio-Environmental Vulnerability). The Parnaíba and São Francisco basins are considered crucial to agricultural expansion and biodiversity conservation. They contain more than 780 [...]

About a third of the restaurants listed on iFood, the food delivery app most used by Brazilians, are “dark kitchens”, according to the first study of the topic conducted in Brazil, and one of only a few worldwide. An article on the study is published in the journal Food Research International. It has eight authors; the first three and the last are researchers at the State University of Campinas (UNICAMP) in São Paulo state. Defined in the article as delivery-only [...]

Tropical mountain ecosystems, including montane forests, are relatively little studied, yet they are home to significant biodiversity and provide important ecosystem services, such as water supply and participation in regulation of temperature and regional and global climate. The data available on mountain vegetation and its dynamics falls far short of what is needed to simulate with confidence its interaction with the atmosphere in response to climate change. A new study published in the [...]
