One of the 25 most endangered primates. [7] Delacour's langur: Trachypithecus delacouri: 234–275 [8] CR [8] [8] The population of the species has radically decreased over the past decade. [8] Silky sifaka: Propithecus candidus: 250 [9] CR [9] [9] Estimate is believed to be a maximum. [9] Tonkin snub-nosed monkey: Rhinopithecus avunculus: 250 ...
Sumatran orangutan (Pongo abelli) Hominoidea is a superfamily of primates. Members of this superfamily are called hominoids or apes, and include gorillas, chimpanzees, orangutans, gibbons, bonobos, and humans. Hominoidea is one of the six major groups in the order Primates. The majority are found in forests in Southeastern Asia and Equatorial Africa, with the exception of humans, which have ...
A species of langur from Myanmar described by Roos et al. 2020.The Popa langur was named for Mount Popa where a population of 111 individuals live. Although yet to be assessed by the International Union for Conservation of Nature (IUCN), it is thought to be Critically Endangered with a total population of 199–259 individuals.
More than 99 percent of all species, amounting to over five billion species, [7] that ever lived on Earth are estimated to be extinct. [8] [9] Estimates on the number of Earth's current species range from 10 million to 14 million, [10] of which about 1.2 million have been documented and over 86 percent have not yet been described.

This is a collection of lists of mammal species by the estimated global population, divided by orders. Lists only exist for some orders; for example, the most diverse order - rodents - is missing. Much of the data in these lists were created by the International Union for Conservation of Nature (IUCN) Global Mammal Assessment Team, which ...
General Non-human Great Ape Susceptibility to COVID-19. Although the susceptibility of COVID infection among many non-human primates is unknown, all catarrhines, monkeys and apes from Africa and Eurasia, have the same set of 12 amino acid residues as human ACE2 where SARs-COVID enters the host cell leading to infection. American monkeys, lemurs ...
Behavioural data for the study, published in the journal Animals, was collected between April 2020 and September 2020 and November 2020 to January 2021, and spanned multiple open and closure ...
Human population projections are attempts to extrapolate how human populations will change in the future. [2] These projections are an important input to forecasts of the population's impact on this planet and humanity's future well-being. [3] Models of population growth take trends in human development and apply projections into the future. [4]
