Researchers have released new maps documenting the “Great Nile Migration,” the Earth’s largest-known land mammal migration across South Sudan and Ethiopia.

The maps chart the seasonal movements of two antelope species, the white-eared kob (Kobus kob leucotis) and the tiang (Damaliscus lunatus tiang). Every year, around 5 million white-eared kob and 400,000 tiang migrate across 100,000 square kilometers (38,612 square miles) of South Sudan’s wetlands and Ethiopia’s Gambella National Park.

About

Biodiversity is a term used to describe the enormous variety of life on Earth. It can be used more specifically to refer to all of the species in one region or ecosystem. Biodiversity refers to every living thing, including plants, bacteria, animals, and humans. Scientists have estimated that there are around 8.7 million species of plants and animals in existence. However, only around 1.2 million species have been identified and described so far, most of which are insects. This means that millions of other organisms remain a complete mystery.

Over generations, all of the species that are currently alive today have evolved unique traits that make them distinct from other species. These differences are what scientists use to tell one species from another. Organisms that have evolved to be so different from one another that they can no longer reproduce with each other are considered different species. All organisms that can reproduce with each other fall into one species. Read more...
