Parkinson’s disease patients who experience freezing of gait (a sudden inability to initiate or continue movement, often resulting in a fall) wake up several times during the night, feel sleepy during the day, and have REM sleep behavior disorder. Rapid eye movement (REM) sleep plays a role in the maintenance of many cognitive processes. These are key findings of a study supported by FAPESP and conducted by researchers at São Paulo State University (UNESP) in Brazil and Grenoble [...]

A female White-eared opossum ( Didelphis albiventris ) found dead in 2021 in Bosque dos Jequitibás Park in the center of Campinas, one of the largest cities in São Paulo state, Brazil, died from rabies meningoencephalitis, according to a group of researchers at the University of São Paulo (USP) and Adolfo Lutz Institute (IAL), the regional reference laboratory, working with health professionals affiliated with public institutions in São Paulo city and [...]

The Amazon rainforest could approach a tipping point, which could lead to a large-scale collapse with serious implications for the global climate system. 

There are no substitutes for native vegetation, but replacing large areas of monoculture with diversified crops in places where agricultural activities are widespread can have beneficial effects on the mammals that still inhabit the region. This is one of the conclusions of a study conducted by researchers at the University of São Paulo (USP) supported by FAPESP. They focused on the northeast of São Paulo state, where the predominant biome is the Cerrado (Brazilian savanna). [...]

Although the interior of São Paulo state (Brazil) has higher human development indices (HDIs) and fewer Black people as a percentage of the population, they account for a larger proportion of deaths from cancer in the Barretos region than in São Paulo city, the state capital, according to a study supported by FAPESP. An article on the study is published in the journal Cancer Causes & Control. In the 18 cities of the Barretos regional health district (RHD), [...]

Interest in forest restoration has increased in recent years, both on the part of companies and financial markets and in academia and government. This is particularly the case in Brazil, whose government has pledged since the 2015 Paris Agreement to restore 12 million hectares of native forest. However, tree planting is costly, while data on species growth and other aspects of reforestation is scant. A study published in the journal Perspectives in Ecology and [...]

Mass migration takes place between December and April on Trindade Island, the easternmost point of Brazil located in the Atlantic about 1,200 km from the coastal city of Vitória, capital of Espírito Santo state. Hundreds of Johngarthia lagostoma land crabs descend steep rocky trails from the upland peaks to the shore, where they mate and release larvae into the ocean. The larvae develop into juveniles, which undertake an even more challenging journey back up to the heights in [...]

The foreseeable effects of climate change on the Caatinga, the semi-arid shrubland and thorn forest biome in Brazil’s Northeast region, will be catastrophic for most terrestrial mammal species that live there. A study reported in the journal Global Change Biology by researchers in Brazil affiliated with the State University of Campinas (UNICAMP), the Federal University of (UFPB) and the Federal University of Minas Gerais (UFMG) forecasts species loss for 91.6% of species assemblages in [...]

At night in the Cerrado, Brazil’s savanna and second-largest biome, larvae of the click beetle Pyrearinus termitilluminans, which live in termite mounds, display green lanterns to capture prey attracted by the bright light. In more than 30 years of expeditions with his students to Emas National Park and farms around the conservation unit in Goiás state to collect specimens, the phenomenon has never been so rare, said Vadim Viviani, a professor at the Federal University [...]
