Challenge Of Change
For much of the year the African Savannah bakes under the oppressive equatorial sun. The dryness is unusual for the equator, whose regions are often covered with dense rainforests and associated with a seasonless annual cycle. In equatorial Africa, animals are still evolving and adapting to the challenge of change. In Tsavo, where it is hotter than other places on the savannah, male lions have lost their usual symbol of dominance, their mane, to keep as cool as possible. And in Gabon, forest animals such as elephants feed on mangrove seeds washed up on the beach, and hippos swim in the surf.
