1. "*" indicates scale was bottomed out.
2. No food adjustments as it's impossible to fairly adjust across the board. You already know my view on food adjustments based on the digestion process of a cat anyhow. Nagarhole figures are raw weights for this reason, also considering the photos don't show gorged specimens.

Guate, in terms of food adjustment, not touching either side is fair as even the old specimens would have food in them. Adjusting one side would create imbalance.

On old specimens being taken young, I agree. Tigers seem to grow for a quite a while, and easily put on weight until 7 or 8 I've noticed. Plus, the rate at which tigers were being killed doesn't bold well for a tiger getting to it's physical peak, and this probably skewed the results downward. I haven't been able to find any hunters distinguishing unfortunately, having that would create a better comparison. At the same time, I believe 3-4 year old specimens are scientifically considered fully grown, but in reality, this isn't the case. So this point may still be even in the end as well.

Like I said before, the P-value is fragile. Maybe if we start adding tigers from Central India and such we'll have a P-value of >0.05, thus not rejecting our null hypothesis.


 

Like I said, I appreciate very much your eforts. You are right in the point that if we adjust one group, then we should adjust the other group and we can't do it correctly as different populations of tigers have different food intakes. For example, Nepalese tigers eat between 14-19 kg in a single night (Sunquist, 1981), while those of Kanha were recorded to eat 18-27 kg in the same time (Schaller, 1967); no other reliable measurements are available in literature, just estimation of up to 40 kg for Amur tigers (Baikov, 1926), but like much of his data, this figures is unreliable. Dr Schaller (1967) estimated that the maximum food intake for a tiger, in 24 hours, is about 1/5 of they weight, which for a large male would be about 45 kg, however, in the reality, the largest food intake ever recorded was for a large male that gorge itself with 35 kg in a single night (McDougal, 1979).

I am still reading the book of Dr McDougal, so I have not found which male was the one that eat that figure. [img]images/smilies/huh.gif[/img]
 

 

I don't think food intake has anything to do with location, I think it has to do with size of the tiger.
Corbetts book that I am reading, the chapter about the Bachelor, he is reported to have the largest pug marks that any of these poachers and indian guides had ever seen, he was measured three times by corbett with a length of 10'7'' and he was reported to be able to devour most of a domestic buffalo in one sitting. I wonder if its possible to determine food intake by body weight %?
