The Amazonian snakebite burden: Unveiling seasonal dynamics in a region with tenfold higher incidence compared to the Brazilian average.

Background: Accidents caused by snakes constitute a serious public health problem in Latin America and worldwide. The situation in the Brazilian Amazon region is neglected, resulting in the highest incidence of cases per capita in the country. Furthermore, the distance from urban areas makes it difficult for the population to access timely and effective medical care, including antivenom treatment.

Threats from climate change for lizard species of a Neotropical mountain range.

Climate change is one of the greatest threats to biodiversity, especially for species of high altitudes. However, biodiversity conservation policies that consider mitigation strategies for long-term climate impacts are still scarce. To analyze the effects of climate change on lizards in tropical mountainous areas, we selected two species from Serra do Espinhaço (Brazil) with different thermoregulation strategies and distributions (Tropidurus montanus and Rhachisaurus brachylepis).

Assessing species reintroduction sites based on future climate suitability for food resources.

The reintroduction of a species that is extinct in the wild demands caution because reintroduction locations may be associated with threats, such as hunting, poor-quality habitat, and climate change. This is the case for Cyanopsitta spixii (Spix's Macaw), which has been extinct in the wild since 2000. The few living individuals were created in captivity and will be used in a reintroduction project within the species' original distribution area, the Caatinga domain (Brazil).
