60-577: The northern white rhinoceros or northern white rhino ( Ceratotherium simum cottoni ) is one of two subspecies of the white rhinoceros (the other being the southern white rhinoceros ). This subspecies is a grazer in grasslands and savanna woodlands. Formerly found in several countries in East and Central Africa south of the Sahara , since 19 March 2018, there are only two known rhinos of this subspecies left, named Najin and Fatu, both of which are female; barring
120-492: A child who was killed. However, the dragons are entwined in the islanders' culture, and the tourists they attract bring much-needed income. Fry and Carwardine help Park rangers to fit a radio collar to a dragon as part of a research project. With protection, tolerance from locals and the ability of female dragons to procreate through parthenogenesis , Fry is confident that the species can survive. The penultimate programme opens with aerial scenes of New Zealand's Southern Alps as
180-417: A female green turtle that has come ashore to lay, and then release new hatchlings back into the sea. Heading further south, the pair dive and snorkel on Indonesia's coral reefs , viewing adult turtles and seahorses . On Mabul Island they find sharks ' fins and jawbones, dried seahorses and sea cucumbers for sale. Carwardine explains that the demand from Asian markets, for food and traditional medicine ,

This translocation was also the subject of a special edition of the BBC's Last Chance to See , titled "Return of the Rhino", presented by Stephen Fry and the zoologist Mark Carwardine . On 25 April 2012, and on 27 May 2012, Suni and Najin mated. Pregnancy of the female rhinos was monitored weekly. Rhinoceros gestation takes 16 to 18 months, so in January 2014
300-446: A handful of animals to over one thousand, showing that anti-poaching patrols are working. At this point, Carwardine, who has been receiving news from contacts though the trip, decides that it is too risky to cross the border, as the eastern DRC is gripped by the Kivu conflict , and the journey to Garamba National Park , where the rhinos were last sighted in 2006 would involve travelling through
360-549: A less welcome surprise when they arrive as a conservation project to relocate the northern whites to a protected area is being abandoned. The pair then turn their attention to primates , visiting a chimpanzee rehabilitation centre and tracking mountain gorillas in Uganda 's Bwindi Impenetrable Forest . At Queen Elizabeth National Park , close to the border with the DRC, Carwardine is pleased to find that elephant numbers have increased from
420-465: A male kākāpō , called Sirocco , mounts and attempts to mate with Carwardine's head. Sirocco found fame after the video of his antics became an internet hit, and was later anointed as New Zealand's "spokesbird for conservation". A Last Chance to See special called "Return of the Rhino" was broadcast on BBC Two on 31 October 2010. The programme followed four of the last remaining northern white rhinos as they were transferred from Dvůr Králové Zoo in
480-544: A male born at Dvůr Králové Zoo in 1980, died from natural causes in Ol Pejeta Conservancy in 2014. Sudan, caught from the wild in 1975, died on 19 March 2018. After the transport, the four rhinos were under constant watch by specialists and staff and lived in specially constructed bomas with access to a 400 by 400 metres (1,300 ft × 1,300 ft) paddock area, allowing them to acclimatize to their new surroundings. Ol Pejeta provides 24-hour armed security for

Subsequently, in the future, it might be possible to specifically mature the cells into specific cells such as neurons and muscle cells, in a similar way in which Katsuhiko Hayashi has grown mouse oocytes out of simple skin cells. The DNA of a dozen northern white rhinos has been preserved in genetic banks in Berlin and San Diego. In August 2019, ten egg cells (five from Najin and five from Fatu) were harvested to be artificially inseminated with
600-524: A separate description is warranted. These distinct groups do not interbreed as they are isolated from another, but they can interbreed and have fertile offspring, e.g. in captivity. These subspecies, races, or populations, are usually described and named by zoologists, botanists and microbiologists. In a monotypic species, all populations exhibit the same genetic and phenotypical characteristics. Monotypic species can occur in several ways: Last Chance to See (TV series) Last Chance to See
660-629: A solitary adult male and a group of one adult male and two adult females. They were the last known wild northern white rhinos, according to the World Wide Fund for Nature . In June 2008, it was reported that the species may have gone extinct in the wild, since there has been no sighting of these four known remaining individuals since 2006, or of their signs since 2007, despite intensive systematic ground and aerial searches in 2008. One carcass has been found. On 28 November 2009, two Russian helicopter pilots reported seeing rhinoceroses in southern Sudan. It

#1732858831954720-475: A species is a binomial or binomen, and comprises two Latin words, the first denoting the genus and the second denoting the species. The scientific name of a subspecies is formed slightly differently in the different nomenclature codes. In zoology, under the International Code of Zoological Nomenclature (ICZN), the scientific name of a subspecies is termed a trinomen , and comprises three words, namely
780-426: A species. Botanists and mycologists have the choice of ranks lower than subspecies, such as variety (varietas) or form (forma), to recognize smaller differences between populations. In biological terms, rather than in relation to nomenclature, a polytypic species has two or more genetically and phenotypically divergent subspecies, races , or more generally speaking, populations that differ from each other so that
840-683: A subspecies was appropriate. There are now only two northern white rhinos left in the world: They both belong to the Dvůr Králové Zoo in the Czech Republic , but live in Ol Pejeta Conservancy in Kenya, Africa. They arrived at the conservancy after an air and road trip on 20 December 2009, along with two male northern white rhinos from the Dvůr Králové Zoo, Suni and Sudan. However, Suni,
900-417: A subspecies. A common criterion for recognizing two distinct populations as subspecies rather than full species is the ability of them to interbreed even if some male offspring may be sterile. In the wild, subspecies do not interbreed due to geographic isolation or sexual selection . The differences between subspecies are usually less distinct than the differences between species.

The second part commits the government and its international partners to increase conservation efforts in Garamba, so the northern white rhinos can be returned when it is safe again. However, the translocation did not occur. In August 2005, ground and aerial surveys conducted under the direction of African Parks Foundation and the African Rhino Specialist Group (ARSG) had only found four animals,

Thus Larus (argentatus) smithsonianus means the American herring gull ; the notation within the parentheses means that some consider it a subspecies of a larger herring gull species and therefore call it Larus argentatus smithsonianus , while others consider it a full species and therefore call it Larus smithsonianus (and
1080-539: Is a wildlife documentary first broadcast on BBC Two in the United Kingdom during September and October 2009. The series is a follow-up of the 1989 radio series, also called Last Chance to See , in which Douglas Adams and Mark Carwardine set out to find endangered animals. In this updated television version, produced for the BBC, Stephen Fry and Carwardine revisit the animals originally featured to see how they're getting on almost 20 years later. In one episode,

In zoology , under the International Code of Zoological Nomenclature , the subspecies is the only taxonomic rank below that of species that can receive a name. In botany and mycology , under the International Code of Nomenclature for algae, fungi, and plants , other infraspecific ranks , such as variety , may be named. In bacteriology and virology , under standard bacterial nomenclature and virus nomenclature , there are recommendations but not strict requirements for recognizing other important infraspecific ranks. A taxonomist decides whether to recognize

Fry compares their noises to lunchtime at the Garrick Club . Their final destination is the Indonesian island of Rinca , home to the Komodo dragon . The world's largest lizard is not to be underestimated: they meet rangers and villagers who have been attacked by dragons, and hear of

Carwardine hopes to return to the park where he and Adams managed to find and photograph the animals 20 years ago. The episode opens with an encounter with a wild southern white rhino, which turns out to be a prank by the rangers as the rhino in question is tame, having been hand-reared. In northern Kenya , Fry and Carwardine have

In Nosy Mangabe , they encountered a wild aye-aye , a rare nocturnal lemur . Carwardine brings Fry to the tree where he saw the creature, but this time they have no luck. The pair embark on a trip through Madagascar to view the island's unique fauna. They encounter brown and ring-tailed lemurs at Berenty Reserve , and

On the Rio Negro , they have an encounter with a group of endangered botos , which take food from their hands. The two fly deeper into the forest to rendezvous with a boat, the Cassiquiari, on the Rio Aripuanã. Further upriver, they meet scientist Marc van Roosmalen and his team. Manatees are known to live in
1560-513: The Czech Republic to Ol Pejeta Conservancy , a protected reserve in Kenya , in a last-ditch attempt to save the subspecies from extinction. The main aim of each episode was to seek out an endangered species and to investigate its plight. In addition, a variety of other animals are filmed on location all over the world. In the opening programme, Fry and Carwardine travel to Manaus in Brazil in search of

In September 2019, scientists announced that they fertilized in vitro the eggs with frozen sperm taken from dead males; two of the resulting embryos were viable. In January 2020, it was announced that another embryo was created using
1740-587: The horn is what the poachers are after. In place of their horns, radio transmitters have been installed to allow closer monitoring of their whereabouts. They are protected round-the-clock by armed guards. Poachers have been selling their horns for $ 110,000 per kilogram ($ 50,000 per pound). Since May 2010, the northern white rhino male Sudan was moved from the initial holding pens to a much larger 700-acre (2.8 km) semiwild enclosure. There he roamed among many African animals, including several southern white rhino females and many plains animals. On 26 October 2011,
1800-556: The Conservancy considered Najin not pregnant, and a male southern white rhino from Lewa Wildlife Conservancy was put to Najin and Fatu enclosure in Ol Pejeta to at least intercross the subspecies. To achieve this, both female northern white rhinos were separated from their male counterparts, which prevented them from producing a pure northern white rhino offspring. In 2015, however, tests conducted by Czech specialists revealed that neither of

However, both of them died later the same year, and no zoo in the world has any northern white rhinos any longer. In 1975, the Dvůr Králové Zoo , located in Dvůr Králové nad Labem , Czech Republic , got six northern white rhinos from Sudan and, in later years, two more from English zoos. One rhino from an English zoo arrived pregnant. The Dvůr Králové Zoo

The two female rhinos belong to the Dvůr Králové Zoo in the Czech Republic but live in the Ol Pejeta Conservancy in Kenya where they are protected by armed guards. According to the latest International Union for Conservation of Nature (IUCN) assessment from 2020,
2280-493: The females are "capable of natural reproduction". According to the director of the Dvůr Králové Zoo, it was possible Najin became pregnant but miscarried shortly thereafter, which resulted in pathological changes in her uterus, preventing another impregnation. At the end of 2015, scientists from the Leibniz Institute for Zoo and Wildlife Research, San Diego Zoo Global , Tiergarten Schönbrunn , and Dvůr Králové Zoo developed
2340-477: The females were coaxed into the larger enclosure. Until 2011, the progress of this attempt at saving the northern white rhinoceros was documented on the initiative's website; and their life in Ol Pejeta Conservancy is commented on the Conservancy's website. Several documentaries are in the works, including an episode of Ol Pejeta Diaries titled "Return of the African Titans" for Oasis HD Canada in fall 2010, and

They watch a hand-reared male called Sirocco broadcast his nightly booming calls. After days frustrated by bad weather, Carwardine's efforts to take photographs of Sirocco take an unexpected turn. The kākāpō climbs on to his head and attempts to mate with him, much to Fry's amusement. He later gets

2520-589: The northern and southern white rhino are possible through IVF, as well as a path to the creation of pure northern white rhino embryos. The San Diego Zoo Safari Park in San Diego , California , had eight wild-caught northern white rhinos. Former residents include: The San Diego Wild Animal Park provided Angalifu's semen to female rhinos at the Dvůr Králové Zoo but the insemination attempts were unsuccessful. The only reproductive animals of this subspecies were transported to Ol Pejeta Conservancy in Kenya. In 2016, it

However, the results of this research were not universally accepted by other scientists. A study in 2016 concluded that the two populations diverged between 0.46 and 0.97 million years ago and found their mitochondrial genomes to be 1.8 % divergent. Based on these findings, the study concluded that classification as

The last known surviving population of wild northern white rhinos was in Garamba National Park , Democratic Republic of the Congo (DRC). In January 2005, the government of the DRC approved a two-part plan for five northern white rhinos to be moved from Garamba National Park to

The quest for a wild aye-aye goes on, and their perseverance is rewarded with a sighting of two animals in the same tree in Mananara Nord National Park. Fry and Carwardine travel to Indonesia and Malaysia to out a rare, endemic species. At Snake Island they encounter a venomous yellow-lipped sea krait , causing Fry to rue his decision to wear open-toed sandals. At Turtle Island , conservationists are working to protect sea turtles . The presenters help to collect eggs from
2760-418: The presenters fly in by helicopter. This was once the natural habitat of the kākāpō , a critically endangered flightless parrot now confined to two offshore islands. Kākāpō numbers were decimated by predators and Māori hunters, and fewer than 100 remained at the time the episode was filmed. (The population of living Kākāpō is 244 (as of 2024). ) Later, they are shown a Māori cloak made from kākāpō feathers in

The subject of the final programme was due to be the Yangtze river dolphin ; however, the species was declared extinct in 2007. Instead, he takes Fry to the Gulf of California on the eastern side of the Baja California Peninsula in Mexico to search for
2880-467: The rank of variety are taken to be names of subspecies (see International Code of Nomenclature of Prokaryotes ). As in botany, subspecies is conventionally abbreviated as "subsp.", and is used in the scientific name: Bacillus subtilis subsp. spizizenii . In zoological nomenclature , when a species is split into subspecies, the originally described population is retained as the "nominotypical subspecies" or "nominate subspecies", which repeats
2940-492: The recently discovered Madame Berthe's mouse lemur , the world's smallest primate, in Kirindy Forest . Carwardine is shocked at the disappearance of the island's rainforests since his earlier visit. Timber provides poor communities with fuel and building material—only the unsuitable baobab trees are spared. Slash and burn agriculture and monoculture also contribute to deforestation. Conservationists are battling to preserve
3000-437: The remaining fragmented islands of forest by planting green corridors and engaging local communities. In a Malagasy village, Fry and Carwardine witness a traditional healing ceremony. The aye-aye has been a victim of cultural beliefs as well as habitat loss, regarded by some natives as a symbol of death. When superstitious villagers encounter the animal, they kill it to prevent a death in their community. Despite their misgivings,
3060-446: The rhino enclosure. To prevent any unnecessary injuries they might inflict on each other while interacting in their fenced area, and give their horns an opportunity to regrow to a natural shape (as their front horns had grown bent by much rubbing against enclosure bars in captivity), all the rhinos were sedated and their horns were sawn off. This also made them less vulnerable to the poaching that drove their species to near extinction, as

The agreement with the Kenyan government expects the rhinos never to be returned to the Czech Republic. The female named Nabire stayed in Dvůr Králové Zoo, because, as Jan Stejskal, a projects coordinator at the zoo, stated, "she is no longer capable of breeding naturally. But it seems she has one healthy ovary and this could provide us with material from which to create an embryo in artificial conditions." Efforts to do so began in autumn 2014. Immediately after

The subspecies name that repeats the species name is referred to in botanical nomenclature as the subspecies " autonym ", and the subspecific taxon as the "autonymous subspecies". When zoologists disagree over whether a certain population

In December 2020, 14 egg cells were retrieved from Fatu; eight of them were fertilised by the sperm of the dead northern white rhino Suni, resulting in two viable embryos. No egg cells were retrieved from Najin. As of February 2024, there are 30 northern white rhino embryos that have been created by BioRescue. The embryos are cryopreserved in labs in Berlin, Germany and Cremona, Italy. The BioRescue team plans to implant northern white rhino embryos in two southern white rhino surrogates by
3300-476: The subspecies is considered "Critically Endangered (Possibly Extinct in the Wild)." Following the phylogenetic species concept , a study in 2010 suggested the northern white rhinoceros may be an altogether different species, rather than a subspecies of white rhinoceros, in which case its correct scientific name would be Ceratotherium cottoni . According to the study, distinct morphological and genetic differences suggest
3360-556: The subspecific name must be preceded by "subspecies" (which can be abbreviated to "subsp." or "ssp."), as in Schoenoplectus californicus subsp. tatora . In bacteriology , the only rank below species that is regulated explicitly by the code of nomenclature is subspecies , but infrasubspecific taxa are extremely important in bacteriology; Appendix 10 of the code lays out some recommendations that are intended to encourage uniformity in describing such taxa. Names published before 1992 in

Carwardine takes Fry to INPA in Manaus, where captive manatees are kept for research. At Tefé , west of Manaus, they plan to join Miriam Rosenthal and her Mamirauá team on a trip to release an injured one-year-old manatee back into the wild. However, on the morning of their departure, Fry trips and breaks his arm in three places. After Fry

However, as of August 2011, no other sightings have been reported, and this population is now considered to have probably gone extinct. At the beginning of 2015, the fully captive northern white rhino population consisted of only two animals maintained in two zoological institutions: in
