Museum find proves exotic ‘big cat’ prowled British countryside a century ago

Canadian Lynx shot in Devon in 1900

April 2013. An old skeleton, found in a warehouse of the Bristol Museum and Art Gallery, of an animal shot around 1900 in Devon has proved to be that of a Canadian Lynx.

The study of the Canadian lynx, rediscovered by research team member Max Blake among hundreds of thousands of specimens at Bristol Museum and Art Gallery, details records unearthed at the museum which showed the animal had originally been mislabelled by Edwardian curators in 1903 as a Eurasian lynx – a close relative of the Canadian lynx.

The animal’s skeleton and mounted skin was analysed by a multi-disciplinary team of Durham University scientists and fellow researchers at Bristol, Southampton and Aberystwyth universities and found to be a Canadian lynx – a carnivorous predator more than twice the size of a domestic cat.

Earliest example of ‘Alien big cat‘ in Britain

The research establishes the animal as the earliest example of an “alien big cat” at large in the British countryside.

1976 Wild Animals Act

The research team say this provides further evidence for debunking a popular hypothesis that wild cats entered the British countryside following the introduction of the 1976 Wild Animals Act. The Act was introduced to deal with an increasing fashion for exotic – and potentially dangerous – pets.

The academics believe such feral “British big cats” as they are known, may have lived in the wild much earlier, through escapes and even deliberate release. There is no evidence that such animals have been able to breed in the wild.

Shot in Devon

The records also showed that the lynx was shot by a landowner in the Devon countryside in the early 1900s, after it killed two dogs. (Another lynx was found in a freezer in 1991 in Norfolk).

“This Edwardian feral lynx provides concrete evidence that although rare, exotic felids have occasionally been part of British fauna for more than a century,” said lead researcher, Dr Ross Barnett, formerly of Durham University and now Marie Curie Fellow with the Natural History Museum of Denmark at the University of Copenhagen.

“The animal remains are significant in representing the first historic big cat from Britain.”

Co-author Dr Darren Naish, from the University of Southampton, added: “There have been enough sightings of exotic big cats which substantially pre-date 1976 to cast doubt on the idea that one piece of legislation made in 1976 explains all releases of these animals in the UK.

“It seems more likely that escapes and releases have occurred throughout history, and that this continual presence of aliens explains the ‘British big cat‘ phenomenon.”

The researchers point out in their paper that Eurasian lynxes existed in the wild in Britain many hundreds of years ago, but had almost certainly become extinct by the 7th century.

Kept in captivity

Morphometric and stable isotope analyses identified the specimen as a Canadian lynx, while analysis of its bones and teeth established it had been kept in captivity long enough to develop severe tooth loss and plaque before it either escaped or was deliberately released into the wild.

Ancient DNA analysis of hair from the lynx proved inconclusive, possibly due to chemicals applied to the pelt during taxidermy.

Julie Finch, head of Bristol’s Museums, Galleries & Archives, said: “Bristol Museum, Galleries and Archives were pleased to be a part of this ground-breaking research, which not only highlights the importance of our science collections, it establishes the pedigree of our 100-year old Lynx and adds to our knowledge and understanding of ‘big cats’ in the UK.

“Our museum collections are extensive and caring for them requires the considerable skills of our collections officers. We have an amazing collection of taxidermy animals on display and we welcome museum visitors to come along, to take a closer look and discover more about the natural world.”

Dr Greger Larson, a member of the research team from Durham University and an expert in the migration of animals, said: “Every few years there is another claim that big cats are living wild in Britain, but none of these claims have been substantiated. It seems that big cats are to England what the Loch Ness Monster is to Scotland.

“By applying a robust scientific methodology, this study conclusively demonstrates that at least one big cat did roam Britain as early as the Edwardian era, and suggests that additional claims need to be subjected to this level of scrutiny.”

The lynx is now on public display at the museum. For further details, click here.

The research was published in the academic journal Historical Biology.

BIG CATS IN BRITAIN

Despite years of claims and alleged sightings, there has never been any proof that big cats are roaming our countryside. A lynx that was shot in Norfolk in the early 1990s was apparently an esapee from a local zoo, and there have been several claims that ‘Small big cats’ such as leopard cats and swamp cats have been run over, there has never been any proof that these land based Nessies exist.

There is, of course, great conspiracy theories that suggest it is all a great police and government cover up, along with UFO and man on the moon. That will be the same police that broadcasted their efforts to destroy a toy tiger on a golf course in Hampshire in 2011.

‘Extinct’ British oil beetle rediscovered in Devon

‘Extinct’ in UK oil beetle rediscovered in Devon

‘Extinct’ oil beetle discovery not seen since 1906

December 2012. A beetle hotspot on the South Devon coast has re-written the record books for the second time in six years with the discovery of an oil beetle which was has not been seen in UK since 1906 and was thought to have been extinct there for more than one hundred years.

Last seen in UK in 1906

Before its rediscovery, the Mediterranean oil beetle (Meloe mediterraneus) had been found in the South East of England in Essex and Kent. The beetle was last recorded in Kent in 1906, and had not been seen since, until rediscovered this autumn. Local naturalist John Walters found the oil beetle on National Trust land between Bolt Head and Bolt Tail on the beautiful south Devon coast, while carrying out a study for the charity Buglife – The Invertebrate Conservation Trust.

Leading beetle expert, Darren Mann of the Oxford University Museum of Natural History confirmed the discovery making this the first record in the UK for over 100 years, and the first ever for South West England.

John Walters said “The 2 to 3 centimetre long matt-black beetle resembles the rare Rugged oil beetle, but the beetles I found were much larger and their larvae were a different colour. I investigated further and was amazed to find that they were a ‘long lost’ species!”

Andrew Whitehouse, Buglife’s South West Manager said, “The rediscovery of this beetle is great news, bringing the total number of oil beetles species in the UK up to five. However all of our oil beetle species remain under threat. The loss of wildflower-rich habitats and the decline in wild bee populations, upon which these beetles depend, are the main threats to oil beetles in the UK. Buglife is working to better understand the needs of oil beetles and how best to conserve them”.

Andy Foster, Biological Survey Team Leader at the National Trust, said: “This is remarkable news, following the discovery of the rare Short-necked oil beetle from the same area of south Devon only a few years ago, and demonstrates the value of detailed studies which can lead to such unexpected results. One can’t help feeling there are other colonies out there just waiting to be found – it’s crucial that we understand where these threatened species survive and understand more about their habitat requirements.”

Oil beetles

Buglife’s national oil beetle conservation project is a partnership project with the National Trust and Oxford University Museum of Natural History and is funded through Natural England’s Species Recovery programme. The project was launched in 2011. Eight species of oil beetles have been recorded in the UK but three are thought to be extinct.

Two ‘Extinct in UK’ beetles rediscovered

Two species that were thought to be extinct, the Short-necked oil beetle (Meloe brevicollis) and now, the Mediterranean oil beetle (Meloe mediterraneus), have now been rediscovered this century – both in south Devon. Both these species are now known from just one site in England however the Short-necked oil beetle was subsequently found on a site in Scotland.

The name ‘oil beetle’ derives from the fact that the adult beetles are able to secrete a toxic oil called cantharadin from their leg joints. It is thought to repel predators. British oil beetles have declined due to habitat loss, changes in land management and a decline in solitary bee populations.

Oil beetle life cycle

Oil beetles are nest parasites of solitary ground-nesting mining bees that emerge in the spring. The adult oil beetles will lay up to 1000 eggs in a burrow in soft or sandy soil. The young larvae are unusual in being very active and long-legged and are known as triungulins after their three-clawed feet. They climb up flower stems and lie in wait for a suitable host bee. When a bee comes to collect pollen and nectar from the flower, the tiny triungulins grab hold of the hairs on the bee’s back and are carried away to the bee’s nest. There the louse-like triungulins drop off, eat the bees eggs and spend the rest of the year growing fat on the stores the bee collected for her own young.

Mediterranean oil beetle

One reason for the Mediterranean oil beetle (Meloe mediterraneus) remaining undiscovered was that specimens were mistaken for the similar-looking Rugged oil beetle (Meloe rugosus).

The adult Mediterranean oil beetle is slightly larger than the Rugged oil beetle, and has a larger thorax. The Rugged oil beetle also has a crease down the centre of the thorax that is absent in the Mediterranean oil beetle. The triungulins (larvae) are probably more distinct with the Mediterranean oil beetles being entirely orange whereas the Rugged oil beetle triungulins have a distinctly dark head.

Piranha in English river … a real piranha?

Devon river team’s piranha shock

A “killer” fish native to South America has been found in a Devon river.

The Environment Agency said its staff were amazed to find a dead piranha in the East Okement tributary of the River Torridge.

The piranha, which has razor-sharp teeth, is generally considered to be the most ferocious freshwater fish in the world.

The 35cm (14in) fish was spotted by Bob Collett, Dave Hoskin and Eddie Stevens during a sampling trip on the river.

Among the species the team would have expected to find in the river were salmon, brown trout, bullheads, stone loach and minnow.

“What we actually discovered was something we would not expect to find in our wildest dreams – we could hardly believe our eyes,” Mr Stevens said.

“After completing 20m of the survey, a large tail emerged from the undercut bank on the far side of the river.

“Our first thought was that a sea trout had become lodged in amongst the rocks and debris collected under the bank, but when it was removed from the river we were speechless to find it was a piranha.”

Tests carried out on the dead piranha revealed it had been eating sweet corn, which proved it must have been kept as a pet.

The Environment Agency said the average size of a piranha was 15 to 20cm (6in to 8in), making the fish found on the East Okement an exceptional size.

A shoal of piranha fish is said to be able to strip the flesh of large animals within minutes. They have also been known to attack humans.

In the wild, piranhas are found in the Amazon basin, in the Orinoco and the rivers of the Guyanas.

The Environment Agency said it believed the piranha was alive when it was put in the river, possibly because it had become too big for its tank.

Spokesman Paul Gainey said: “Whilst piranhas can’t survive the colder climates of the UK, this latest find highlights a real issue – that releasing unwanted exotic pets or plants into rivers can have serious consequences for native wildlife.

“Rather than dumping things in the wild, we would urge people to seek advice about what to do with exotic species.”

However, is this really a piranha? Practical Fishkeeping has doubts about that:

However, Practical Fishkeeping believes that the fish in the Agency’s image appears to be a Red-bellied pacu, Piaractus brachypomus, a species that can reach over 80cm and weigh more than 25kg.

This largely herbivorous species was once a common aquarium fish, but the species has become less common as the keeping of larger-growing species has fallen out of favour and many shops have become unwilling to re-home fish purchased by fishkeepers unable to adequately meet their long-term needs.

Talking about a real piranha, though about one who has been dead for far longer than the piranha (or pacu?) in England: Fossil Megapiranha sheds light on evolution of piranha teeth: here.

Britain: ‘Killer Folkestone piranha’ not piranha at all [but pacu]: here.

This monstrous fish is a tambaqui, a close relative of the piranha. Fortunately, it doesn’t share its cousin’s flesh-eating lifestyle. Instead, the 30-kilogram tambaqui (or pacu) is a vegetarian. It swims through the flooded forests of the Amazon, eating fruits that drop from the overhanging trees. In doing so, it acts as an vehicle for the Amazon’s seeds, carrying them to distant parts of the jungle within its gut: here. And here.
