UV radiation increases by roughly 10 percent for every 1,000 meters gained in elevation.
Although covered in thick dark fur, mountain gorillas possess heavily pigmented skin that protects against ultraviolet radiation at high elevations. UV exposure increases with altitude, and their montane habitat exposes them to stronger solar radiation than lowland forests. The pigmentation acts as a biological shield, reducing cellular damage beneath thinner fur regions like the face and hands. Combined with dense hair insulation against cold, this dual adaptation allows survival in a climate that swings between misty chill and intense sunlight. Few primates combine high-altitude living with equatorial latitude. The result is a rare convergence of cold adaptation and UV resilience.

At elevations above 10,000 feet, UV intensity can rise dramatically compared to sea level. Mountain gorillas traverse open forest clearings where sunlight penetrates canopy gaps. Their skin must endure both cold nights and bright daytime radiation. This layered adaptation mirrors challenges faced by human mountaineers, yet gorillas evolved it naturally. Their bodies balance thermal and solar extremes simultaneously.
Climate shifts altering cloud cover could increase UV exposure further. Habitat degradation that reduces canopy density may also intensify sunlight penetration. Even subtle atmospheric changes influence physiological stress. The mountain environment that shaped them is not static. Adaptations forged over millennia now confront accelerating environmental change.
