Serengeti UPSC NOTE

 Why in News

  • Researchers have finally unravelled a longstanding question on why Serengeti zebra, wildebeest, and gazelle, which share limited food resources, follow the same migratory routes, in a body size dependent way

  • The researchers used novel data to show how a balance of species interactions and ecological factors regulate this process. 

  • They say competition pushes zebra ahead of wildebeest, and wildebeest then eats plants in a way that facilitates the development of newer growth for the trailing gazelle.

  • The Serengeti-Mara ecosystem is a vast and awe-inspiring natural wonder, spanning across Tanzania and Kenya. 

  • It's renowned for its incredible biodiversity, breathtaking landscapes, and the iconic Great Migration - the largest terrestrial mammal migration on Earth.

Geography and landscape:

  • Encompasses over 30,000 square kilometers, including savannas, grasslands, woodlands, rivers, and lakes.

  • Diverse topography, ranging from rolling plains to the majestic Ngorongoro Crater Highlands.

  • Varied rainfall patterns create distinct seasons, influencing animal movements and vegetation growth.


  • Home to over 70 large mammal species, including lions, elephants, zebras, giraffes, and cheetahs.

  • Over 500 bird species, including migratory birds like flamingos and eagles.

  • Rich insect and reptile life, playing crucial roles in the ecosystem's food chain.

Keystone species and the Great Migration:

  • Wildebeest are the ecosystem's keystone species, their annual migration shaping the landscape and benefiting other animals.
