What is genetic rescue, and can we use it to save endangered species?

Galactic Polymath・2 minutes read

The Florida panther faced near-extinction in 1994 due to genetic issues, low fertility, and heart defects, prompting genetic rescue efforts to introduce diversity and prevent extinction. The broader species, Puma concolor, has various common names due to its historical range overlapping with different communities and habitat loss from European settlers.

Insights

  • Genetic rescue through introducing genetically distinct individuals to mate with endangered panthers is crucial for improving survival rates and genetic diversity, preventing extinction.
  • The Florida panther population faced near-extinction in 1994 due to low fertility, heart defects, poor immunity, and genetic issues, highlighting the critical importance of conservation efforts to preserve endangered species.
