Colour and development of manes in male lions varies between regions, among populations and with age of lions. In general, the Asiatic lion differs from the African lion by a less developed mane. The manes of most lions in ancient Greece and Asia Minor were also less developed and did not extend to below the belly, sides or ulnas. Lions with such smaller manes were also known in the Syrian region, Arabian peninsula and Egypt, whereas Barbary and Cape
Apex predator example, reduction in the population of sperm whales, apex predators with a fractional trophic level of 4.7, by hunting has caused an increase in the population of large squid, trophic level over 4 (carnivores that eat other carnivores). This effect, called mesopredator release, occurs in terrestrial and marine ecosystems; for instance, in North America, the ranges of all apex carnivores have contracted whereas those of 60% of mesopredators have grown in the past two centuries. Because apex predators have powerful effects on other predators, on herbivores, and on plants, they can be important in nature conservation. Humans have hunted many
