The lion is the world's second-largest big cat and serves as an apex land predator in Africa. [1] [2] The saltwater crocodile is the largest living reptile and the dominant predator throughout its range. [3] [4] The great white shark (bottom) is one of the top marine predators; however, the orca (top) is known to prey upon them. Thus, great ...
Without keystone species, the ecosystem would be dramatically different or cease to exist altogether. Some keystone species, such as the wolf and lion, are also apex predators. The role that a keystone species plays in its ecosystem is analogous to the role of a keystone in an arch. While the keystone is under the least pressure of any of the ...
If eland bulls find any of their predators nearby, they bark and attempt to attract the attention of others by trotting back and forth until the entire herd is conscious of the danger. [25] Some of their main predators include lions, African wild dogs, cheetahs, and spotted hyenas. Eland calves are more vulnerable than adults to their predators ...
A savanna or savannah is a mixed woodland-grassland (i.e. grassy woodland) biome and ecosystem characterised by the trees being sufficiently widely spaced so that the canopy does not close. The open canopy allows sufficient light to reach the ground to support an unbroken herbaceous layer consisting primarily of grasses.
The protected area of Benin which is defined as a National Protected Area System is in northern Benin, mostly with a woody savanna ecosystem. It covers 10.3% of the nation and is part of the three-nation W-Arly-Pendjari Complex (WAP) (of which 43%, 36% and 21% is in Benin, Burkina Faso and Niger respectively). [1] [2] [3] [4]
The African savanna hare is a medium-sized species growing to a length of between 41 and 58 cm (16 and 23 in) with a weight of between 1.5 and 3 kilograms (3.3 and 6.6 lb). The ears have black tips, the dorsal surface of head and body is greyish-brown, the flanks and limbs are reddish-brown and the underparts are white.
To test the theory, researchers created a simplified virtual simulation of a dinosaur ecosystem. ‘Giant dinosaur carcasses might have been important food for Jurassic predators’ Skip to main ...
In Niger, populations occur in the northern parts of the country in the Ténéré desert and in the southern savanna region of W National Park. Records in Togo date to the 1970s. The Saharan cheetah is thought to be regionally extinct in Morocco , Western Sahara , Senegal , Guinea , Guinea-Bissau , Sierra Leone , Côte d'Ivoire and Ghana .
