Who is the "king" of tigers? - Bengal or Amur

[Master Chief]

I am sorry, but I have more more doubt about what you wrote. This is what I am dubious about your statement.
If you and your friends are true. Then it have already been changed in animal journal like more than 20 years ago.  
 
When I found about the guy who made those chart and comparison data. He graduated from university of Guatemela with agricultural economics and agricultural plant science degrees. I don't even see any of his research papers done by himself. Bascially, he doesn't have any of real life experience of big cats. I guess definitely not the tiger since tiger is only living in Asia.
After I read what you wrote, you don't look like you are actually studying or tracking real tiger in wild and zoo. You're definitely not a keeper in zoo. How do you even know about the pure Bengal or mixed Bengal in captive zoo around the world? I don't think you can prove like that by sending some emails to a few professor and reading some books and articles.


I know these people aren't 100% perfect. But this sentences came from the big cat rescue people who's actually interacting with big cat. (From Rishi)
"Scientists in Russia report that no tigers immobilized by the Russian team have weighed as much as those in Chitwan. It probably is a function of habitat quality. Siberian tigers have the potential for being the largest, and captive ones are larger than captive Bengals. But in the wild the prey base in Russia is not abundant enough for those tigers to realize their full potential. Prey is more scattered and the Russian tigers need huge territories to capture sufficient food, so much more energy is expended in the food que"


This is from the Association of Zoos & Aquariums of the USA.
"The Amur tiger is the largest big cat on earth. Though comparable in weight to Bengal tigers, with males averaging 176 kg (390 lbs) and females averaging 118 kg (260 lbs), Amur tigers’ bodies and fur tend to be longer."

I can say that today's Amur tiger in wild is lighter than Bengal tiger.
Nevertheless, prey is scarce in Russia.
I don't believe that Bengal tiger would grow that huge size as you mentioned if prey density in India is the same in Russia.
They are probably small and light just like current Amur tiger these days.

Amur tiger have almost no food intake in their home unlike the Bengal tiger or African lion. We don't know size of the Amur tiger if they are living in high prey density environment.


I remember I read one old paper in wildfact. It says that the majority huge records of the Bengal tigers were cattle killers. It was also said that the Bengal tiger average weight was lower than lion back in past. But they got heavier than Amur and African lion these days.
Bengal tigers would never be the same size in India and Nepal if they are living in Russia with low prey biomass. Reply
