Invasive Dogs in the Antarctic Turbo-Evolving
Imagine this post-apocalyptic scenario: *an island twice the size of Sicily with a terrain and environment that make you feel like you're somewhere in Iceland or the wilderness of Norway. The island is home to a sparse, meager human population who subsist primarily on sheep farming as a source of livelihood, but who live under the constant threat of danger by the island's first and only apex superpredators. Packs of wild (feral) dogs that rule all parts of the island from its densest wilderness to the outskirts of human settlements.* Descendants of those brought to the island by these people's very ancestors have reverted to an entirely wild state and occupy a niche occupied in similar-looking terrains on the opposite of the world by their distant Wolf ancestors.
This scenario I have just read to you is a real phenomenon and it is happening at the very end of the world: *Isla Grande de Tierra Del Fuego.* The southernmost tip of South America, directly across from Antarctica, is in the midst of an invasion that has escaped global attention.

Invasive Cats in the Antarctic Turbo-Evolving
We’ve all seen how domestic cats have spread and multiplied with the resultant damage that they’ve done in just a few years ,and in lands that have never seen any kind of wild cat but only with our domestic variety, what we need to do is finding a way to control them ,because like the rabbit they will just continue to spread as time goes by ,again adding stress on the local wild life populations
In other words, They came down with wisdoms to teach and share with innocents peoples!!
I do not believe a cat can survive in the Antarctic! I think this is a Hoax click video.
Cats aren't really domesticated in the same sense as dogs and have to get used to people while dogs are naturally friendly to humans.
Australian dingo was brought from India before European arrival
Funny snakehead are invading our waters while they are invading china crazy
🌴😒 My entire family was completely wiped out 5-6 generations ago.
all the nepalis crying in the comments that their kings where once tibetan🤣🤣😂😂😂
Didn't Australia have a feral rabbit problem decades ago. I do remember the Australians putting up rabbit proof wire fencing to protect their crops from roving bands of wild rabbits. What we may be looking like is a classic "Prey - Predator" cycle of rabbits and cats. With the cats growing large enough to successfully hunt large rabbits. So it looks like one eco-problem is solving another. In a classic sin-cos cycle.
We do save the kittens. Feral cats here in OZ are 200 year reversions back to naturalised Wild Cats. Pregnant females seek our 100 year old disused Shearing Shed. Where they have kittens under the floor. I feed the wild mothers cat food and trap their Kittens when they are around four to five weeks old. These babies we tame which is as easy as domestic kittens and move on into the cat the adoption system here in South Australia. Where they are desexed inoculated and micro-chipped This action in my experience is the kindest and most loving outcome for the baby cats and the wild life they won’t kill. They are removed from the Wild Cat community and initiated back into the Domestic Tribe. Their parents cannot be reverted only the kittens. However cats breed like rabbits and have been recognised as the top Apex predator on Earth and it is lucky they are small or they would eat us. The naturalised wild cats kill a colossal number of native animals a year so their reversion back to domestics is an all round win win solution for the wild life and the kittens. Unlike their parents who are naturalised Wild cats these small Kitten are immediately domesticated and become normal loving cute kittens. If wild cats come to your rural property give this a try it works and plenty of folk are happy to give them homes.
Well… it’s Australia after all…
North America. Brown bear dominates mountain lion.
Not jaguars 😮💨 SW is different and then in Alaska they have to compete with super packs of grey wolves and Siberian tigers that’s have crossed in winter
They definitely get big in central NSW shot an seen heaps growing up use to think about them alot as a kid to if i was outside in the dark by myself
I don't care how anyone else feels I live on 100 acre property and when I first bought my property it was overrun with wildcats I have started hunting I'm like squirrels I put in a small dent in the population of my property but I have not gotten rid of all of them it is a small war I don't even live in Australia I've got hundreds of wild cats on my property
When did 11 pounds become large for a cat?? Where do you live that has such tiny cats? 5kg is normal small breed cat weight and would be severely underweight for medium or large breeds. My small breed skinny calico is between 8-9 kg and my Norwegian forest cat was around 13kg at his prime.
👍👍🙏🏻❤️
Did billionaires buy Australia and New Zealand?
Your video is incorrect, the asiatic wildcat is a separate species from the african wildcat with three known subspecies: the steppe wildcat (Felis (Felis) ornata ornata), the middle-eastern wildcat (Felis (Felis) ornata gordoni), and the caucasian wildcat (Felis (Felis) ornata caucasica), this species is basal to both the european and african wildcats, the european wildcat now has only four valid subspecies: the mainland european wildcat (Felis (Felis) silvestris silvestris), the scottish wildcat (Felis (Felis) silvestris grampia), the tyrrhenian islands wildcat (Felis (Felis) silvestris sarda), and the cretan wildcat (Felis (Felis) silvestris cretensis) while the african wildcat currently has only two valid subspecies: the north african wildcat (Felis (Felis) catus catus) and the south african wildcat (Felis (Felis) catus cafra).
There's at least one area in Washington state, including North Cascades and Mt Baker-Snoqualmie Nat'l Forest, where Black Bears have also established as top predators. They've also evolved to aggressively hunt down deer, esp. deer calves. Recreation sites in the area, responded by trying to dissuade this practice, as one that is unpleasant to tourists. The deterrence, such as fire hoses, has limited, localized, effect. Interestingly, North Cascades is an area for the proposed re-establishment of Grizzly Bears.
Save Australian wildcats
Feral canids are an interesting phenomenon for sure. Not sure why half your footage is of Dholes (Cuon) though. They're only relatively distantly related to Canis species. Additionally, the island wasn't always an island and only became isolated relatively recently (geologically and evolutionarily speaking). It was once home to the Jaguar (Panthera onca mesembrina) and an Arctotherium sp. (short faced bear) and had a diverse herbivorous megafauna assemblage until around 8,000 ybp or so, and humsn arrival. I'm unsure if Puma or Smilodon occurred there too, but it wouldn't be surprising if they did. So no, the island hasn't always been predator free, nor always an island. Reintroduction of jaguar or Puma would likely decimate feral dog population too, they tend to do poorly in natural landscapes with big cats. www.researchgate.net/figure/Radiocarbon-dates-of-fossil-remains-of-mammals-found-in-archaeological-sites-from-Tierra_tbl2_358359770 www.researchgate.net/publication/235332612_Tigers_and_Wolves_in_the_Russian_Far_East_Competitive_Exclusion_Functional_Redundancy_and_Conservation_Implications
How in the world did they get loose there? Who goes to an untamed wilderness and thinks 'You know what I need to bring? A cat." A dog would make a lot more sense. By the way, I appreciate that you seem to be a real human narrator and not A.I. but check the pronounciation of archipelago again. Thank you for this informative video.
I just have to say that the occurrence of Ursus arctos east of the Mississippi River in most locations both in prehistoric and historical times in North America is hotly contested. In any case, it is interesting to see the American black bear taking advantage of the ecological gap left by the absence of it's larger relative.
After looking at many photos of wild dogs from Latin America and reading a news article from the 1890s, I believe that American dingoes inhabit Latin America down to Tierra del Fuego, even the Caribbean. American dingoes have inhabited the New World for about 9,000 years. I also believe that American dingoes outcompeted Argentine warrahs (Dusicyon avus), like how dingoes and New Guinea singing dogs outcompeted thylacines.
Actually the puma was extripated from Tierra Del Fuego in historical times. Therefore, pumas once roamed the landscape of Tierra Del Fuego.
Pumas have never been on Tierra Del Fuego.
@eclectic.explorations are you sure?
@@eclectic.explorationsMaybe they should be introduced as a dog-control measure. Once man starts "F-ing" with an ecosystem, everything goes haywire.
Thunder thunder thunder thunder Cats!
The tundra wolves would dominate these bears I call b.s.
Ripu malla was the king of the western Nepal (Present day katmandu which was later ruled by shah dynasty )and western Tibet, and Ripu malla was the King khasa kingdom which comes under Kshetri or chhetri or Newari ...it was in 14 century when Buddhist culture was introduced in Tibet, by MALLA dynasty ...that's the reason in Nepali we called Momo there is no word called momo existed in Tibetan dictionary dumplings are both different yet ... And that's how it was introduced the architech of Newari culture influence both china and Tibet..Nepali language is khas bhasha
I mean your regular house cats are also a pest to wildlife. They each kill dozens of small animals each year for no reason
I'm from Italy, there have been, over the years, many reports of "panthers" in remote areas of Tuscany, I believe it might be, again, ferals going gigantic to hunt wild boars, which Tuscany has plenty of.

Hmmm... Guess I will have to search for hard information. But thanks for making me aware of this interesting situation.
YOU ARE THE CREATURE FAR WORST THAN THOSE FERAL DOGS
They need hunters to remove them
Farmers on the island do actively hunt them, but keep it low key to avoid scrutiny from outsiders and also residents of the island’s few towns.
Australia: the only place on earth since guns were invented where people lost to the wildlife. what's the record now? +2 animals? -2 Australian army/govt./public?
anybody else wonder how the hell this guy got 6000 subscribers?
This behavior is more a return to norm vs evolution. Black bears were very present on the plains of North America before man pushed them out.
MORE PICTURES AND VIDEO OF THE FERAL DOG OF TIERRA DEL FUEGO PLEASE😮🤪🤔🤡
I say this in the most respectful manner, please stop recording in a wind tunnel.
The Argentine goverment once breeded a new dog bread meant to be adapted to antarctica, mixing breeds from canada and siberia. It was called the Argentine Polar Dog, which was a success, but the international community forced Argentina to euthanize the dogs, claiming they would eat the native seals and they were spreading the flue to them. Both were lies, as the polar dog clearly wasnt left unleashed to eat the seals or penguins, and the variant of the flue that affects dogs cant be transmitted to seals.
