Analysis of data from over 5,000 territories and 1,924 species of toads and frogs shows that two of the main theories about the biodiversity of plants, birds, and mammals in these habitats do not explain the richness of anuran amphibians on their own.

A FAPESP-funded study using whole-genome data from across the continent tells a more detailed story of its settlement. The study was featured on the cover of Nature.
A study indicates that the availability of food for the largest cat in the Americas is a key factor in its presence in conservation areas of the biome, which covers approximately 15% of Brazil.
Small amounts of this anthropogenic soil, created by ancient Amazonian populations, have demonstrated a potent effect on the growth of two species of interest for reforestation.
A study led by Brazilian researchers shows that species are being replaced by generalists, and there is no trend toward savannization; however, recovered areas are more vulnerable.

A survey of 1,116 new species descriptions published between 1990 and 2025 reveals improved quality, though authors from the Global North use more lines of evidence in their studies.

Scientists observed that bacterial communities in colonies change depending on the food leafcutter ants offer to their symbiotic fungus. This research may aid in the search for new molecules for biofuels and bioremediation.

One of the most complete sequencing projects ever performed on snakes worldwide serves as a reference for all jararaca vipers, which may contribute to new discoveries about toxins and the conservation of the species on Queimada Grande Island in Brazil, where it is critically endangered.

Study reveals that evolutionary divergence occurred before ecological divergence, enabling these insects to feed on both wood and soil. Future discoveries may be applied to the production of biofuels.

Analyses of biological material from six migratory and one resident species in Brazil indicate similar concentrations of some persistent organic pollutants (POPs), including DDT and the formicide mirex, even in birds with different feeding habits.

Study confirms that the symbiosis between fungi and algae that dissolves rocks and was widely distributed across Earth 410 million years ago helped form the first soils.

Batrachochytrium dendrobatidis is responsible for the decline of toad and frog populations across the globe. The origin of the fungal strain was the subject of a study led by researchers at the State University of Campinas.
The parasitic mites were found on juvenile arachnids in the Butantan Institute collection. The larvae of Araneothrombium brasiliensis were collected in Rio de Janeiro. Previously, the genus had only one known species in Costa Rica.
Water accumulated in the tanks of these plants living high up in trees has much higher concentrations of nitrogen, phosphorus, calcium, potassium, magnesium, sulfur, and iron than rainwater. Plants irrigated with this nutrient-rich water produced almost twice as many leaves.
