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 ...
The species is listed as Endangered on the IUCN Red List and is most threatened by habitat destruction, human population growth and movement (as well as ongoing civil unrest and political infighting), with commercial poaching being, by far, the most prominent threat. Bonobos typically live 40 years in captivity; their lifespan in the wild is ...
Species population is a science falling under the purview of population ecology and biogeography. Individuals are counted by census, as carried out for the piping plover ; [ 3 ] [ 4 ] using the transect method , as done for the mountain plover ; [ 5 ] and beginning in 2012 by satellite, with the emperor penguin being first subject counted in ...
