Context- The sloth bear, tiger and dhole are among 36 apex predators worldwide affected the most due to road construction in their native habitats, a study published February 21, 2022, in the journal Nature, has stated.
- Eight of the top 10 apex predators most affected due to roads running through their habitat are from Asia.
- Other important predators affected by roads across continents include:
- Iberian lynx (Europe)
- African wild dog (Africa)
- Lion (Africa and Asia)
- Ethiopian wolf (Africa)
- Leopard (Asia and Africa)
- Striped hyena (Asia and Africa)
- Canadian lynx (North America)
- Wolverine (North America and Eurasia)
- Brown Hyena (Africa)
- Fosa (Madagascar)
- Spectacle Bear (South America)
- Maned Wolf (South America)
- An apex predator, also known as an alpha predator or top predator, is a predator at the top of a food chain, without natural predators.
- Apex predators are usually defined in terms of trophic dynamics, meaning that they occupy the highest trophic levels.
- For example, wolves prey mostly upon large herbivores (primary consumers), which eat plants (primary producers).
- The apex predator concept is applied in wildlife management, conservation and ecotourism.
- Apex predators affect prey species’ population dynamics and populations of other predators, both in aquatic and in terrestrial ecosystems.
- They are central to the functioning of ecosystems, the regulation of disease, and the maintenance of biodiversity.
- Humans are not considered apex predators because their diets are typically diverse, although human trophic levels increase with consumption of meat.
