Could a Siberian tiger survive in Alaska?

Image
This is a hypothetical or theoretical question. Certainly, yes, Siberian tigers could easily survive in Alaska in terms of the seasonal temperatures. Alaska appears to be warmer on average than Siberia and Siberian tigers live in Siberia! It is just a question of whether there is sufficient prey animals in Alaska. And I think the second point is the one which would make it difficult for a Siberian tiger to survive in Alaska. And whether they'd be left alone and not persecuted or hounded as tourist attractions by humans. Siberian tiger. Image: Britannica. Around three quarters of Alaska is described as sub-Artic and therefore it lacks the habitat and prey animals required to sustain a Siberian tiger. If that is true, then the remaining quarter is acceptable in terms of supporting Siberian tigers and I'm sure that a quarter of Alaska is still a very large area! One person who commented on this topic said that Siberian tigers have an enormous area in which to live i.e. Siberia, bu...

What is the natural or ideal habitat of the tiger?

Tigers want and need access to large terrestrial animals as prey. Therefore what is good for these prey animals is good for the tiger. You'll find the highest density of tigers and the largest home range size where there is an abundance of large terrestrial prey.   What is the natural or ideal habitat of the tiger? A habitat that supports its ideal prey animal: large ungulates. This is related to habitat diversity and primary productivity. 'Primary productivity' refers to the rate at which energy from sunlight is converted to organic substances by photosynthesis.  This is a reference to the tiger food chain. Where the habitat is able to convert sunlight into an abundance of plants which feeds the herbivore prey animals of the tiger there will be an ideal and natural habitat for the tiger. In practical terms this is where 'grassland and forest form a mosaic; a mix of vegetation types supports a rich ungulate community'. Ungulates are hoofed mammals. Note: tigers a...

Why the tiger is endangered according to Dr Desmond Morris

In 1996 Dr Desmond Morris's book Cat World was published. Okay, that is 16 years ago and the stresses on tiger conservation since then have mounted because the four reasons for the fall in tiger populations listed below are still present and getting worse. Bengal tiger cooling off in water. Photo: Pixabay. Tigers are great swimmers. In 1996 the human population of Asia had more than doubled since 1950 to 3,000 million. It will be double that in another 30 years. The 'living space for the tigers is vanishing year by year'. Yes, it is a simple matter of space. Tigers need lots of it: hundreds of square miles (male: up to 300 square kilometres). Secondly he writes that sport hunting still exists. I disagree with this because nowadays when tigers are shot they are not shot for the entertainment factor, they are shot dead for their body parts which are very valuable in Chinese medicine. Yes, there is still some illegal trophy hunting of the tiger but sport hunting is scarce ...
