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 lives 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 Park , female 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.
Tiger and Dog Mating oh my god tiger sex with Dog - video dailymotion
A wildlife photographer captured a stunning image of two male lions in Kenya's Masai Mara. After the release of the photograph, taken in August at Kenya's Masai Mara National Reserve, Ezekiel Mutua, the chief executive of the Kenya Film Classification Board, blamed humans or maybe demons for the male-on-male mounting. The mounting behavior isn't actually sexual. And the official jumped the gun on attributing human motivations to animal behavior, experts said.
Till couple of years back it was difficult to study tigers in their natural environment, but with the establishment of protected reserves it has become much easier to know about their life style, daily routine and social activities. Females reach sexual maturity around 3 to 4 years of age and males mature at about 4 to 5 years. In tropical climates, females may come into oestrus throughout the year, though mating seems to be more frequent during the coolest months November to April. In temperate regions, she enters oestrus and mate only during the winter months. The courtship and ultimately mating, starts with tigress coming into oestrus the time when a female is receptive and capable of conceiving young , which she does every three to nine weeks, and her receptivity lasts three to six days.
The Federation predicts that due to the increase in fertility the population will triple over the next 10 years " This edit seems suspect as it doesnt fit with the rest of the entry. And I can not find a refrance on the page linked. The reference does not refer to this assertion. It looks like a Colbert-vandalism to me, so I removed it. As I have pointed out in past edits, it has actually been disproven by researchers that the lion mane protects males in fights, not proven.
