![]() ![]() We discuss the mechanisms through which males with more exaggerated traits could obtain a mating advantage, namely male-male fights or female mate choice. Whereas morphological variables did not significantly affect the intensity of male-male encounters, the number of females attending male-male encounters strongly affected the number of agonistic displays by the two males. Top 10 Facts About Silverback Gorillas National Geographic Expeditions No Monkeying Around: Amazing Facts about Mountain Gorillas How much do you know about this critically endangered. There are currently less than a thousand silverback gorillas left in the world. Between 20, a series of group splitting events was observed at. Sometimes, multi-male mountain gorilla groups split, forming two new groups that are each led by a different silverback. In a fight, a silverback will certainly beat you Fully grown male gorillas are almost six times stronger than a man 10. One of the groups currently studied at Karisoke in Rwanda (group Pablo) descends from Group 5, which was habituated by Dian Fossey in the late 1960s. The number of females belonging to a mature male positively correlated with the male crest size, body length, and musculature. They have been observed to live slightly longer in captivity. The dominant silverback keeps other members in check. Among most gorilla species, interaction with other groups is very rare though it has been observed in western lowland gorillas. Silverback gorillas live in small family groups consisting of one male leader (the silverback) and several females with their offspring. A gorilla group usually consists of one dominant male silverback, other males, juveniles, females and their young. Female gorillas are likely to use the information to find potential. Behavioral data were also collected during 312 male-male encounters involving 67 mature males in order to estimate their level of aggressiveness. An adult male silverback gorilla is typically twice as big as an adult female, weighing up to 400 pounds and standing up to 6 feet tall. Author Edward Wright and his team recorded 25 wild adult male silverback gorillas at Volcanoes National Park in Rwanda. Body length, head-crest size, musculature development, and extent of the grey color on the back were assessed in 87 nonbreeding and breeding mature males. We developed photogrammetric methods for distance collection of morphological data from silverback males frequenting the Lokoué forest clearing in Odzala-Kokoua National Park, Republic of the Congo. Such traits are likely to have evolved by sexual selection, either because they confer advantages during male-male fights or because females prefer males with more dimorphic traits. Mature males are twice the size of females and have grey fur on their backs and a fibrous, adipose crest on their heads. The western lowland gorilla (Gorilla gorilla gorilla) is one of the most sexually dimorphic primate species. ![]()
