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).

New records and modelling the impacts of climate change on the black-tailed marmosets.

Climate change represents an unprecedented threat to global biodiversity and, for many species, gaps in our knowledge of their biology remain acute. Gaps in baseline knowledge, such as confirmed identifications (Linnean shortfalls) and adequate collections (Wallacean shortfalls), need to be minimized with new studies, since this is often critical for effective conservation. Despite the increase in scientific research on primates in the southwest of the Brazilian Amazon, little is known about the species Mico nigriceps (Ferrari & Lopes, 1992) Primates, Platirryni.

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).
