Biopesticide Is Harmless To Mammals But Can Wipe Out Colonies Of Wasps That Benefit Plants
Publicado em 09 dezembro 2023
Social wasps of the species Mischocyttarus metathoracicus did not distinguish between healthy nestmates and individuals infected by the fungus Beauveria bassiana, which can kill entire colonies
Some wasps and bees are able to recognize sick nestmates by smell and can prevent their entry into the nest to avert infection of the entire colony, assuring its survival and that of the species in the long run.
A study supported by FAPESP and described in an article published in the journal [...]

Researchers Profile Pollutants Present In Important River Basin In São Paulo State, Brazil
Publicado em 01 dezembro 2023The Piracicaba, Capivari and Jundiaí (PCJ) River Basin comprises 76 municipalities in São Paulo state, Brazil, with more than 5.8 million inhabitants and a drainage area of more than 14,000 square kilometers. These three rivers and their tributaries are essential sources of drinking water, energy, irrigation for agriculture and water for industrial processes. Demand is very high, and the resulting water shortage is exacerbated by the climate crisis. This is not the only problem [...]ver notícia -
Subsistence Poaching Has Little Impact On Biodiversity In Amazon’s Environmental Protection Areas
Publicado em 25 outubro 2023The 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.

Study Reveals Areas Of Brazilian Amazon Where No Ecological Research Has Been Done
Publicado em 17 outubro 2023Many 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 [...]ver notícia -
Climate Change May Affect 40% Of Biodiversity In Semi-Arid Portion Of Brazil’s Northeast By 2060
Publicado em 22 setembro 2023The 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 [...]ver notícia -
Legal Mining Sites In Brazil Store 2.55 Gigatonnes Of CO2 In Vegetation And Soil
Publicado em 15 setembro 2023As 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 [...]ver notícia -
Hydroelectric Power Plants In Brazil Threaten Turtles That Depend On Rapids
Publicado em 15 setembro 2023A 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 [...]ver notícia -
Climate Change-Induced Drought May Transform Parts Of Amazon’s Rainforests Into Savannas
Publicado em 29 agosto 2023A 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 [...]ver notícia -
Novel Socio-Environmental Vulnerability Index Pinpoints Sustainability Issues In Brazilian River Basins
Publicado em 11 agosto 2023Brazilian 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 [...]ver notícia -
