The International Union for Conservation of Nature (IUCN) Red List of Threatened Species, also known as the IUCN Red List or Red Data Book, founded in 1964, is an inventory of the global conservation status and extinction risk of biological species. A series of Regional Red Lists are produced by countries and organizations, which assess the risk of extinction to species within a political management unit.
Dioscorea is a genus of over 600 species of flowering plants in the family Dioscoreaceae, native throughout the tropical and warm temperate regions of the world. The vast majority of the species are tropical, with only a few species extending into temperate climates. It was named by the monk Charles Plumier after the ancient Greek physician and botanist Dioscorides.
Ravenala is a genus of monocotyledonous flowering plants. Classically, the genus was considered to include a single species, Ravenala madagascariensis, commonly known as the traveller's tree, traveller's palm or East-West palm, from Madagascar. It is not a true palm but a member of the family Strelitziaceae. The genus is closely related to the southern African genus Strelitzia and the South American genus Phenakospermum. Some older classifications include these genera in the banana family (Musaceae). Although it is usually considered to be a single species, four different forms have been distinguished. Five other species were described in 2021, all from Madagascar: Ravenala agatheae Haev. & Razanats., R. blancii Haev., V.Jeannoda & A.Hladik, R. grandis Haev., Razanats, A.Hladik & P.Blanc, R. hladikorum Haev., Razanats., V. Jeannoda & P.Blanc, R. madagascariensis Sonn., et R. menahirana Haev. & Razanats.
The eastern lesser bamboo lemur, also known as the gray bamboo lemur, the gray gentle lemur, and the Mahajanga lemur is a small lemur endemic to Madagascar, with three known subspecies. As its name suggests, the eastern lesser bamboo lemur feeds mainly on bamboo. The lemurs of the genus Hapalemur have more manual dexterity and hand–eye coordination than most lemurs. They are vertical climbers and jump from stalk to stalk in thick bamboo forests.
Eupleres is a genus of two species of mongoose-like euplerid mammal native to Madagascar that are known as falanoucs. They are primarily terrestrial and consume mainly invertebrates.
The fauna of Nicaragua is characterized by a very high level of biodiversity. Much of Nicaragua's wildlife lives in protected areas. There are currently 78 protected areas in Nicaragua, covering more than 22,000 square kilometers (8,500 sq mi), or about 17% of its landmass.
Dalbergia hirticalyx is a species of legume in the family Fabaceae. It is found only in Madagascar. It is threatened by habitat loss.
Lemurophoenix halleuxii is a species of palm tree, the only species in the genus Lemurophoenix. It is found only in Madagascar. It is threatened by habitat loss and overcollection. There are perhaps 300 mature individuals remaining in the wild.
The white-footed sportive lemur, white-footed weasel lemur, or dry-bush weasel lemur is a species of lemur in the family Lepilemuridae, the sportive lemurs. It is similar in appearance to other lemurs in the family, with a grey back, a pale grey to white ventral side, and a light brown tail. It is a nocturnal animal that moves through the forest using a vertical clinging and leaping technique. It is endemic to Madagascar, inhabiting the southern subtropical or tropical dry shrubland. It is threatened by habitat loss due to agriculture practices and charcoal production.
Lantzia is a genus of amphibious pulmonate gastropods in the family Lymnaeidae. It is monotypic, being represented by the single species Lantzia carinata. It is endemic to montane streams on the Indian Ocean island of Réunion.
Ambohitantely Special Reserve is a 5,600-hectare (14,000-acre) wildlife reserve of Madagascar.
The gray-headed lemur, or gray-headed brown lemur, is a medium-sized primate, a cathemeral species of lemur in the family Lemuridae. Until a taxonomic revision in 2008, it was known as the white-collared brown lemur or white-collared lemur. It lives in south-eastern Madagascar. In 2005, satellite imagery estimates showed approximately 700 km2 (270 sq mi) of total remaining habitat within its geographic range. It is highly threatened by hunting and habitat loss, and was considered to be among the 25 most endangered primates in 2006–2008. It is currently listed as Critically Endangered by the International Union for Conservation of Nature (IUCN) due to a highly restricted range, and has been named one of "The World's 25 Most Endangered Primates."
Dioscorea orangeana, is a tuberous vining flowering plant in the genus Dioscorea, endemic the Forêt d’Orangea near Antsiranana in Madagascar, from which it derives its name. The tuber is possibly edible, and unlike most other Dioscorea species, the tuber has many finger-like lobes as opposed to a single tuber. Because the plant is new to science and the possible harvesting by local populations, the conservation status of Dioscorea orangeana is of great concern.
The World's 25 Most Endangered Primates is a list of highly endangered primate species selected and published by the International Union for Conservation of Nature (IUCN) Species Survival Commission (SSC) Primate Specialist Group (PSG), the International Primatological Society (IPS), Global Wildlife Conservation (GWC), and Bristol Zoological Society (BZS). The IUCN/SSC PSG worked with Conservation International (CI) to start the list in 2000, but in 2002, during the 19th Congress of the International Primatological Society, primatologists reviewed and debated the list, resulting in the 2002–2004 revision and the endorsement of the IPS. The publication was a joint project between the three conservation organizations until the 2012–2014 list when BZS was added as a publisher. The 2018–2020 list was the first time Conservation International was not among the publishers, replaced instead by GWC. The list has been revised every two years following the biannual Congress of the IPS. Starting with the 2004–2006 report, the title changed to "Primates in Peril: The World's 25 Most Endangered Primates". That same year, the list began to provide information about each species, including their conservation status and the threats they face in the wild. The species text is written in collaboration with experts from the field, with 60 people contributing to the 2006–2008 report and 85 people contributing to the 2008–2010 report. The 2004–2006 and 2006–2008 reports were published in the IUCN/SSC PSG journal Primate Conservation,, since then they have been published as independent publications.
Furcifer belalandaensis, also commonly known as the Belalanda chameleon or the Sangoritan'i Belalanda, is a species of chameleon that is endemic to Madagascar. It was identified and described by Édouard-Raoul Brygoo and Charles Domergue in 1970. The International Union for Conservation of Nature rated this species as Critically Endangered on their Red List of Threatened Species. The World Wide Fund for Nature is trying to save this species from extinction.
Dioscorea ovinala is a species of yam in the family Dioscoreaceae. It is endemic to Madagascar and grows mostly in dry deciduous forests.
Dioscorea quartiniana is a climbing tuber geophyte in the family Dioscoreaceae. It is native to Benin, Botswana, Burundi, Chad, Congo, Côte d'Ivoire, Eritrea, Ethiopia, Gambia, Ghana, Kenya, Madagascar, Malawi, Mozambique, Namibia, Nigeria, Rwanda, Sierra Leone, South Africa, Sudan, Tanzania, Uganda, Zambia, and Zimbabwe. This species occurs in forests, grasslands, and rocky areas.
Dioscorea stipulosa is a type of climbing tuberous geophyte of the family Dioscoreaceae. It is endemic to the Eastern Cape province of South Africa.
Dioscorea acuminata is a herbaceous vine in the family Dioscoreaceae, which is listed as an endangered species by the IUCN Red List. It is indigenous to the central plateau of Madagascar where it occurs on rocky substrate in a grassland-woodland mosaic habitat. There is confusion as to whether the tuber is harvested for consumption by humans as field researchers likely misidentified Dioscorea maciba as this species. However, the IUCN Red List also has an entry for D. maciba which does not cite that species as being consumed by humans.
