ON THE EDGE OF EXTINCTION - A - THE TIGER (Panthera tigris)

THE RELATION BETWEEN HEEL WIDTH AND WEIGHT IN WILD MALE AMUR TIGERS IV (continuation of III)

g - Heel width of Amur tigers captured in the Sichote-Alin Biosphere Reserve 1992-2004

g1 - Two tables with information about the heel width and weight of male Amur tigers 

In 2005, 'Tigers in the Sichote-Alin Zapovednik: Ecology and Conservation' (Miquelle et al.) was published (in Russian only). The title of chapter 7 is 'Morphological Indicators of the Amur tiger' (Kerley et al.). It has a number of tables. Most of these were posted in AVA about a decade ago. 

The table below is from Chapter 7. It was used for this post, because it has information about the heel width of the tigers captured in the Sichote-Alin Zapovednik:

The table has no weights, but my guess is the tigers used for the table are the same as those featuring in another table and that table has specific information about all individuals captured in the Sichote-Alin Zapovednik in the period 1992-2004:

Table 7.3 is based on 12 male tigers, whereas the other table is based on 11 males. It's very likely that the 11 males in the last table were also used for Table 7.3. This means both tables can be used to get to get to conclusions on the relation between heel width and weight in the 11 male tigers used in both tables. 

Before starting on the conclusions, we need to know a bit more on the 11 tigers in the second table. 

g2 - Information about the 11 male tigers used in both tables 

From the top down: 

♂ 01 - no details available  
♂ 02 - weighed 3 times (range 170,1-201,8 kg.) 
♂ 03 - young adult (assumption)
♂ 04 - no details available  
♂ 05 - longest measured  
♂ 06 - no details available 
♂ 07 - young adult (assumption)
♂ 08 - no details available
♂ 09 - euthanized
♂ 10 - released from rehabilitation
♂ 11 - young adult (assumption)

g3 - Averages

1 - The 11 male tigers averaged 169,45 kg. (range 125-200)
2 - Without the euthanized 125 kg. tiger, the average of the remaining 10 male tigers is 173,9 kg. (range 146-200)
2 - The 3 young adults (without the euthanized 125 kg. tiger) averaged 149,33 kg. (range 146-155)
3 - The 7 adult tigers (without the euthanized 125 kg. tiger) averaged 184,43 kg. (range 170-200)

g4 - Conclusions

1 - The average heel width of 11 male tigers captured in the period 1992-2004 was 11,4 cm. (range 10,5-12,8)
2 - The average weight of these 11 tigers was 169,45 kg. (range 125-200) 
3 - The 11 male tigers captured in the Sichote-Alin Zapovednik in the period 1992-2004 averaged 169,45 kg. and 11,4 cm. in heel width 

h - The relation between heel width and weight in male brown bears in northeastern Siberia

The table below, posted by 'Warsaw' in AVA quite some time ago, was added for comparison. When I changed from Windows-7 to Windows-10 some months ago, vital information was lost. I'll try to find tre source of the table when I have time:
