A study published in Nature Climate Change predicts that 36% of anurans’ habitats worldwide will soon be threatened by a combination of rising temperatures and water scarcity. Brazil has the greatest diversity of anurans in the world and some of the most vulnerable anuran habitats.

Scientists have organized structural barriers to food systems change into a comprehensive framework, with the aim of empowering policymakers, civil society organizations, and researchers to tackle food sustainability challenges more effectively.

The researchers synthesized a molecule inspired by a substance present in Nectandra leucantha (canela-seca or canela-branca). Animal trials have produced promising results.

School addresses the connections between academic research and reparation processes, recognizing the relevant role of the university in promoting the right to memory and social reparation initiatives. Registrations are due on January 27, 2025.

Plant collections are full of surprises. It may take decades to id plant samples, but it’s worth the effort, especially when some of these species are not known from anywhere else on Earth.

Researchers tested the effects of the plant’s methanolic extract and an isolated alkaloid substance, palmatine, on mice. The results were promising.

Land use and land cover (LULC) analysis has become increasingly significant in environmental studies due to its direct impact on the environment. Changes in LULC affect the ecological and climatic balance, in addition to increase the terrain’s susceptibility to hazardous phenomena. However, one of the key challenges in analyzing LULC time series is the presence of classification errors, which can result in invalid transitions. Invalid transitions, which represent unlikely or impossible land cover changes in a given period, can lead to misinterpretations of causes or consequences of hazard events, especially in highly susceptible areas, such as mountainous regions. 

The viral strain found in the dead animals on Anchieta Island in Ubatuba was the variant transmitted by vampire bats, which probably fed on the capybaras’ blood at a time of habitat disturbance.
