Recent Research Breakthroughs
Indri Song Complexity
Scientists discovered Indri songs have rhythm patterns similar to human music, with complex beat structures and categorical rhythms.
Genetic Diversity Study
Genetic analysis revealed critically low genetic diversity, highlighting urgent need for population connectivity.
Territory Mapping
Advanced GPS tracking mapped precise territory boundaries, revealing overlap zones crucial for population management.
Climate Impact Assessment
Research showed Indri populations are highly vulnerable to temperature increases, requiring immediate habitat protection.
Help Save the Indri Indri
