Extinction is the termination of a kind of organism or of a group of kinds (taxon), usually a species. The moment of extinction is generally considered to be the death of the last individual of the species, although the capacity to breed and recover may have been lost before this point. Because a species' potential range may be very large, determining this moment is difficult, and is usually done retrospectively. This difficulty leads to phenomena such as Lazarus taxa, where a species presumed extinct abruptly "reappears" after a period of apparent absence.
The International Union for Conservation of Nature (IUCN) Red List of Threatened Species, founded in 1964, is the world's most comprehensive inventory of the global conservation status of biological species. It uses a set of precise criteria to evaluate the extinction risk of thousands of species and subspecies. These criteria are relevant to all species and all regions of the world. With its strong scientific base, the IUCN Red List is recognized as the most authoritative guide to the status of biological diversity. A series of Regional Red Lists are produced by countries or organizations, which assess the risk of extinction to species within a political management unit.
Papagomys is a genus of very large rats in the tribe Rattini of the subfamily Murinae. It contains two species, which are known only from the Indonesian island of Flores:
The fringed fruit-eating bat, is a species of bat native to South America.
The masked finfoot or Asian finfoot is a highly endangered aquatic bird that was formerly distributed throughout the fresh and brackish wetlands of the eastern Indian subcontinent, Indochina, Malaysia and Indonesia. Like the rest of the family, the African finfoot and the sungrebe, the relationship to other birds is poorly understood.
The inland hill rat is a species of rodent in the family Muridae. It is found only in central and southern Sulawesi, Indonesia.
The Manusela mosaic-tailed rat is a species of rodent in the family Muridae. It is found only in Indonesia. It lives in the rainforests on the island of Seram in Indonesia. Specimens of it weigh 66.5g and have a head and body length of 118-135mm and a tail length of 126–140mm.
The Bramble Cay melomys, or Bramble Cay mosaic-tailed rat, is a recently extinct species of rodent in the family Muridae and subfamily Murinae. It was an endemic species of the isolated Bramble Cay, a vegetated coral cay located at the northern tip of the Great Barrier Reef in Australia. Described by researchers as having last been seen in 2009 and declared extinct by the Queensland Government and University of Queensland researchers in 2016, it was formally declared extinct by the International Union for Conservation of Nature (IUCN) in May 2015 and the Australian government in February 2019. Having been the only mammal endemic to the reef, its extinction was described as the first extinction of a mammal species due to anthropogenic climate change.
Bartels's rat is a species of rodent in the family Muridae. It is found only in West Java, Indonesia, including in Gunung Gede Pangrango National Park.
The Raffles' banded langur, also known as the banded leaf monkey or banded surili, is a species of primate in the family Cercopithecidae. It is endemic to Singapore and southern Peninsular Malaysia. The species underwent taxonomic revisions in 2019 and 2020, in which two former subspecies were elevated to separate species. As a result, the Raffles' banded langur meets the criteria for being listed as vulnerable by the IUCN. It is mainly threatened by habitat loss.
Canut's horseshoe bat is a species of bat in the family Rhinolophidae. It is endemic to Indonesia.
An endling is the last known individual of a species or subspecies. Once the endling dies, the species becomes extinct. The word was coined in correspondence in the scientific journal Nature. Alternative names put forth for the last individual of its kind include ender and terminarch.
The Roloway monkey is an endangered species of Old World monkey endemic to tropical West Africa. It was previously considered a subspecies of the Diana monkey. The species is classified as Critically Endangered due to habitat loss and their continued hunting because of the bushmeat trade. The Roloway monkey is mainly an arboreal species, for the most part inhabiting forests in Ghana and some reserves in South-Eastern Côte-D'Ivoire. More specifically, studies have shown that the C. diana roloway is primarily concentrated in the Tanoé forest of the Côte-D'Ivoire because of their heavy threats to extinction and lack of habitat. It is still difficult to gather data on wild subjects, as they have low populations in a vast forest, but they are a unique and vanishing species.
Coryphomys is an extinct genus of rats, known from sub-fossils found on Timor. Its name is Greek for "top-of-the-head mouse" or "summit mouse".
Defaunation is the global, local or functional extinction of animal populations or species from ecological communities. The growth of the human population, combined with advances in harvesting technologies, has led to more intense and efficient exploitation of the environment. This has resulted in the depletion of large vertebrates from ecological communities, creating what has been termed "empty forest". Defaunation differs from extinction; it includes both the disappearance of species and declines in abundance. Defaunation effects were first implied at the Symposium of Plant-Animal Interactions at the University of Campinas, Brazil in 1988 in the context of Neotropical forests. Since then, the term has gained broader usage in conservation biology as a global phenomenon.
The mountain anoa(Bubalus quarlesi) also known as Quarle's anoa, is a species of buffalo endemic to Sulawesi. Its closest relative is the lowland anoa, and it is still a debate as to whether the two are the same species or not. It is also related to the water buffalo, and both are classified in the genus Bubalus.
The lowland anoa(Bubalus depressicornis) is a species of buffalo endemic to Sulawesi. Its closest relative is the mountain anoa, and it is still a debate as to whether the two are the same species or not. It is also related to the water buffalo, and both are classified in the genus Bubalus.
The Timor giant rat is an extinct species of giant rat described in 2010. It is known only from sub-fossils that were found on Timor Island, Indonesia. It is related to the murines of New Guinea. Archaeological research on East Timor has revealed the bones of rats weighing up to 6 kilograms when adult.
