澳大利亚昆士兰州生物作业代写:种群趋势

The apes achieve sexual maturity at 18 months of age and show sexual preparation through the tongue. Mating and childbirth can occur at any time of the year. Mature females give birth every two years. For black marmosets, the pregnancy is 180 days and produces a descendant. At birth, both male and female black marmosets are blond, but males become black when they are two and a half years old. In other species, the color of young people and adults is the same for both sexes. Adolescent males and females leave their parents’ ranks to join unrelated forces. The average life expectancy of apes is 15 to 20 years. The conservation status of simian IUCN varies from species to species, from least concerned to endangered species. The population trends of some species are unknown, while the population trends of other species are decreasing. Part of the range of apes is protected.
