Mane colour varies and darkens with age; research shows its colour and size are influenced by environmental factors such as average ambient temperature. Mane length apparently signals fighting success in male—male relationships; darker-maned individuals may have longer reproductive Thesis on fast food burger king and higher offspring survival, although they suffer in the hottest months of the year.
The presence, absence, colour and size of the mane are associated with genetic precondition, sexual maturity, climate and testosterone production; the rule of thumb is that a darker, fuller mane indicates a healthier animal. In Serengeti National Parkfemale lions favour males with dense, dark manes as mates.
The hormone testosterone has been linked to mane growth; castrated lions often have little to no mane because the removal of the gonads inhibits testosterone production. In the Chauvet Cave is a sketchy drawing of two maneless lions that appearing to be walking side-by-side. One lion is mostly obscured by the other; the obscuring lion is larger than the obscured one and is depicted with a scrotum.
White lion White lions owe their colouring to a recessive allele The white lion is a rare morph with a genetic condition called leucism that is caused by a double recessive allele. It is not albino; it has normal pigmentation in the eyes and skin. They were removed from the wild in the s, thus decreasing the white lion gene pool.
Nevertheless, 17 births have been recorded in five prides between and Intermittent bursts of activity continue until dawn, when hunting most often takes place.

Such a group is called a " pride ". Groups of male lions are called "coalitions". Large prides, consisting of up to 30 individuals, have been observed. A lion may switch lifestyles; nomads can become residents and vice versa. Females lions stay closer to their natal pride.
Therefore, female lions in an area are more closely related to each other than male lions in the same area. The reasons for the development of sociality in lionesses — the most pronounced in any cat species — are the subject of much debate.
Increased hunting success appears to be an obvious reason, but this is uncertain upon examination; coordinated hunting allows for more successful predation but also ensures non-hunting members reduce per capita calorific intake.
Some females, however, take a role raising cubs that may be left alone for extended periods. Members of the pride tend to regularly play the same role in hunts and hone their skills.
The health of the hunters is the primary need for the survival of the pride; hunters are the first to consume the prey at the site it is taken. Asiatic lion prides differ from African prides in group composition. Male Asiatic lions are solitary or associate with up to three males, forming a loose pride.
Pairs of males rest and feed together, and display marking behaviour at the same sites. Females associate with up to 12 other females, forming a stronger pride together with their cubs. They share large carcasses with each other but seldom share food with males.
Female and male lions associate only when mating. Males in coalitions of three or four individuals exhibit a pronounced hierarchy, in which one male dominates the others. Dominant males mate more frequently than their coalition partners; during a study carried out between December and Decemberthree females were observed switching mating partners in favour of the dominant male.
Its prey consists mainly of mammals — particularly ungulates — with a preference for blue wildebeestplains zebraAfrican buffalogemsbok and giraffe. Lions kill other predators such as leopardcheetah and spotted hyena but seldom consume them. In Octobera pride of up to 30 lions killed and consumed eight African bush elephants that were between four and eleven years old.
The prey-to-predator weight ratio of 10— Cooperatively hunting lions are usually successful. Males attached to prides do not usually participate in group hunting. They take advantage of factors that reduce visibility; many kills take place near some form of cover or at night. To protect their cattle from such attacks with that knowledge in mind, farmers have found it effective to paint eyes on the hindquarters of each cow, which is usually enough to make hunting lions think they have been seen and select easier prey.
They also kill prey by enclosing its mouth and nostrils in their jaws, which also results in asphyxia. Cubs suffer most when food is scarce but otherwise all pride members eat their fill, including old and crippled lions, which can live on leftovers.Fast Food Review: The BK Veggie Burger from Burger King Posted August 10th, | am by Heather So I’m on Burger King’s website trying to decide what I want for lunch something that hasn’t yet been covered on GrubGrade.
