A study conducted by Brazilian researchers affiliated with São Paulo State University (UNESP), the Federal University of São Carlos (UFSCar) and the Federal University of Viçosa (UFV) has shown how three pesticides widely used by farmers in Brazil—imidacloprid, pyraclostrobin and glyphosate—affect native stingless bees of the species Melipona scutellaris. Whether they are used singly or combined, the pesticides impaired the bees’ ability to move about and [...]

As the impacts of climate change increasingly affect the daily lives of residents in several countries, including Brazil, the resilience of forests, especially tropical ones such as the Amazon, has become a frequent topic of research. In addition to studying various factors that influence the way vegetation reacts to global warming, scientists are seeking to improve vegetation models – tools that play a crucial role in understanding and managing ecosystems, contributing to biodiversity [...]

A consortium made up of researchers from more than ten countries, including Brazil, the United States and some European nations, is running simulations of the past and future climate in South America with unprecedented resolution. The aim is to create a computer visualization model that more accurately represents the hydroclimatic processes that occur in the region to help decision makers implement more effective measures to adapt to the impacts of climate change. The work was presented at a [...]

The theories offered by the dominant literature in political science today to try to explain the sources of the political polarization that has endangered democracy around the world are adequate for the United States and Europe, but do not make sense for the countries of Latin America. For this reason, greater collaboration among political scientists is needed to identify other, more plausible hypotheses for the phenomenon that the region is also experiencing. The assessment was made by [...]

Strategies deployed for the restoration of degraded land have had promising results in Brazil’s semi-arid region, improving the microbial properties of the soil and contributing to a return of native ecosystem services. The techniques include removal of cattle or restriction of their access to specific areas of pasture; cultivation of cover crops; and terracing to control erosion. Recovery of soil microbial properties maintains biodiversity and raises crop yields, contributing to [...]

Global warming may be interacting with regional rainfall and deforestation to accelerate forest loss in the Amazon, pushing it towards partial or total collapse. Research published on 14 February 2024 in Nature , has identified the potential thresholds of these stressors, showing where their combined effects could produce a ‘tipping point' – in which the forest is so fragile that just a small disturbance could cause an abrupt shift in the state of the ecosystem. The study [...]

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 [...]

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 [...]

In an article published in the journal Ecography, a group of Brazilian researchers reports the results of a review of the scientific literature on reptiles published between 1960 and 2021, considering the more than 11,000 species described since the eighteenth century. According to the authors, who are affiliated with the Federal University of Goiás (UFG) and the State University of Campinas (UNICAMP), 15% of the articles published in the period discussed ten species (four turtles, [...]
