Conservationists in Brazil's Paraná state vaccinated black-faced lion tamarins for the first time.

The effort aims to protect these critically endangered primates from diseases that could devastate their small population. The coastal restinga area, a unique ecosystem, faces increasing threats from development and climate change, making such conservation measures crucial.

Researchers carefully moved through the forest, carrying cages with the tamarins, marking a significant step in wildlife preservation efforts.

The long-term vulnerability of these primates remains high due to habitat loss and disease. The ecological degradation of their restinga environment could further endanger their survival.

What is the long-term climate outlook for this region?

Climate change threatens the coastal restinga ecosystem with rising sea levels, increased storm surges, and altered rainfall patterns. These changes could lead to habitat loss and reduced biodiversity, impacting species like the black-faced lion tamarin.

The outlook is negative due to ongoing environmental pressures.
