This true about I'm wrote in here. From: Vratislav Mazak - Big Cats and Cheetah - publication. In captivity is more hybrids with unknown haplotype. Probably is fact - that recently captured barbary lions is not really barbary lions, but hybrids with unknown origin! Because barbary lions in captivity is a mistake. For 100% pure breed is nobody from captured barbary lions in all zoos of the world! Is that clear! Yes, I sayed from this citated book and a fact that is nobody barbary lion in captivity with 100% pure breed and with unique DNA marked by a really barbary lions, which is actually extinct subspecies of lion. And another fact is sayed: that recently barbary lions from captivity is mix much more subspecies of lion. And for this point: recently captured barbary lions don't have 100% pure breeds and unique origin DNA. Because it isn't true barbary lions! Really origin DNA belong to only extinct lion subspecies! And it: pure barbary lions, which is extincted!  |

Well have we got conclusive evidence that we have 100% purebreed barbary lion in captivity? Have any DNA results been published showing Yes? Peter may have further info provided which would give us a straight Yes or No to this. Well, haven't had much time to update the Barbary Lion web page, but hope to finish it this month. To answer your question, I can't say that they have found evidence for an 100% pure barbary lion. But new evidence shows that at least offspring of the original barbary lion still contains Barbary genes. But I have to do more reading on the articles I've collected and recieved. Wildlink International in association with Professor Helmut Hemmer and Dr Joachim Burger of the University of Mainz finally started the "Urgent Population Assessment". It suggests that hybridisation may not have happened that much and that some zoo populations have been kept in seperate breeding lines. And that even if they are not 100% pure they are hybrid Barbary Lions, so a breeding programm to preserve the Barbary genes and maybe when not pure a selective breeding programm is needed. As soon as I know more, I will let you know. I want to read everything very carefully for the upcoming updates page and the different scientific opinions. But for now, I will still see them as extinct, not yet extinct in the wild. But that opinion of me may or may not change when finished reading....we'll see. Peter |

Return of the royal Barbary lion Matt Walker
Editor, Earth News A royal stud book could help return the majestic Barbary lion to the wild. Conservationists have created a stud book detailing every descendant of a group of lions once owned by the Sultan of Morocco. These blue-blooded royal lions, all captive, are suspected to be the last Barbary lions in existence. The stud book will help establish a breeding programme, and could also settle a controversy over whether the Barbary lion was a unique subspecies. The Barbary lion is one of the most enigmatic of all large predators, both due to its impressive appearance and uncertainty over its fate. Once numerous across north Africa, the Barbary lion was the most physically distinctive type of lion, including those living elsewhere in Africa and Asia. Conservationist Simon Black It had an extensive mane, and differences in the shape of its head included a more pointed crown and narrow muzzle. People at the time also talked of it being larger, with different coloured eyes to other lions, though it is unclear whether either difference was real. "Historical records suggest that certain behaviours in Barbary lions were also distinctive, for example, they tended to live in pairs or small family groups rather than the prides familiar in Africa," says Simon Black, of the Durrell Institute of Conservation and Ecology at the University of Kent in Canterbury, UK. The last firm record of a Barbary lion is an animal shot in Morocco in 1927, though there is circumstantial evidence that Barbary lions may have survived in the wild in the Atlas Mountains till 1942. However, even by 1899, the lions were becoming rare in the wild, with those seen most often belonging to the Sultan of Morocco. In 1912, these lions were moved from an original captive location near the Atlas Mountains to a lion garden at the Royal Palace in Rabat. When the last Sultan was forced to abdicate in 1953, the lions were moved to two zoos, but on his return in 1955, 17 were returned to the Palace. In 1973, their descendants were moved to Rabat zoo at Temara. Later, further examinations suggested that these zoo lions shared the characteristics of Barbary lions. "There is strong circumstantial evidence, therefore, that the animals at Rabat zoo were a relic from the original Barbary lions collected from the wild," says Black. However, the possibility that some Barbary lions survive, and they may be the last remnants of a lost subspecies of lion, has become an extremely marketable concept. "It is not uncommon for zoos to advertise [that they possess a Barbary lion] when there is little or no evidence to back up the fact," Black says. Worse, those lions that are true descendants of the original Moroccan royal lions are in danger of dying out. Breeding exchanges To prevent this, Black and colleagues Nobuyuki Yamaguchi, Adrian Harland and Jim Groombridge have created a Barbary lion stud book, that identifies the surviving individuals, their locations, their interrelatedness and their line of descent from the original captive Moroccan population as far back as records are known. The researchers based the stud book on a review of the handwritten zoo records in Rabat kept from 1969 to 1998, plus a detailed review of breeding records across zoos worldwide kept from 1974 onwards. Alongside details of the stud book, published in the European Journal of Wildlife Research, Black's team also calls for a managed and co-ordinated breeding approach to optimise the overall captive population of Moroccan royal Lions. "Now that we have this information, zoos can come together and plan breeding exchanges to avoid inbreeding, ensure genetic diversity is maintained and with it animal health and population viability," says Black. "In this way, if the opportunity exists to re-establish the population in the future, it is not lost by the lions dying out in captivity now," he says. "Several zoos are still keen to continue breeding the animals. They deserve the constructive support of the scientific community." Also that will allow time to perform genetic tests on the lions and "buy time" for scientists to further examine evidence to support whether or not these animals are true representatives of the now extinct subspecies, he says.

As a non-scientist, I think this whole thing with dividing a species into subspecies is problematic and contra-productive as far as endangered species is concerned. We might end up with a lot of small populations of individual subspecies, each of them too small to survive. In that way, this compulsion to name new subspecies will only help their demise. A good example is the Amur Leopard. There are only 30 or so left and they're probably doomed. The population used to be connected with the North Chinese Leopard, so why cant this population be boosted with a little foreign blood if necessary?
The Barbary Lion probably had some adaptations to living in a mountain climate, and even if no "racially pure" Barbary Lion exist today, those genes are worth saving if the chance to rewild them in a similar climate should ever appear.

Examining the Extinction of the Barbary Lion and Its Implications for Felid Conservation
Simon A. Black, Amina Fellous, Nobuyuki Yamaguchi, David L. Roberts AbstractEstimations of species extinction dates are rarely definitive, yet declarations of extinction or extirpation are important as they define when conservation efforts may cease. Erroneous declarations of extinctions not only destabilize conservation efforts but also corrode local community support. Mismatches in perceptions by the scientific and local communities risk undermining sensitive, but important partnerships. We examine observations relating to the decline and extinction of Barbary lions in North Africa. Whilst the extinction predates the era of the scientific conservation movement, the decline is relatively well documented in historical records. Recently unearthed accounts suggest Barbary lions survived later than previously assumed. We use probabilistic methods to estimate a more recent extinction date for the subspecies. The evidence presented for a much later persistence of lions in North Africa, including generations when sightings were nil, suggests caution when considering felid populations as extinct in the wild. The case raises the possibility that captive animals descended from the Moroccan royal collection are closer contemporaries to wild Barbary lions. Furthermore, our results highlight the vulnerability of very small lion populations and the significance of continued conservation of remnant lion populations in Central and West Africa.

Revealing the maternal demographic history of Panthera leo using ancient DNA and a spatially explicit genealogical analysis www.biomedcentral.com/1471-2148/14/70#B19An extinct species of lions of North Africa may soon be resurrected as scientists have found the animals' close genetic links in Indian lions. DNA tests have revealed that Indian lions are closely related to Barbary lions, according to a new research published in the journal BMC Evolutionary Biology. According to Dr Ross Barnett, lead author of the study who sequenced the DNA from the skulls of two Barbary lions once held in Britain's Tower of London, four of the six Barbary lions exhibited sequence identical to that of the extant Indian lion. Scientists described the DNA sequencing as "noteworthy" as Indian lions showed incredibly close relationships with the Iranian and the Barbary lion populations of North Africa despite being geographically distant. According to the research, the restoration of the extinct North African Barbary lion has attracted the attention of conservationists both inside and outside North Africa. Although there has been circumstantial evidence that the Barbary lion could have survived in captivity, studies have shown that the most likely descendants of wild Barbary lions do not appear to be Barbary. The close genetic relationship between the Barbary lion and the extant Indian lion gives hope to conservationists. "In the tiger, another charismatic felid species, studies of ancient mitochondrial DNA have suggested a close relationship between the extinct central Asian Caspian tiger and the extant Amur tiger," scientists noted in the study. "This has allowed conservationists to discuss the translocation of Amur tiger stock to occupy the former range of the Caspian tiger with support from the World Tiger Summit. "Similarly, if no examples of purebred Barbary lions can be found within the zoo population, there might be scope for restoration of the North African lion population using the closely related Indian lion," the scientists said. www.ibtimes.co.uk/extinct-barbary-lions-africa-could-be-back-life-soon-1443182 |
