figure 6.5. Relationship between the Riney kidney fat index and the total kidney
fat index for mountain lion carcasses from the Black Hills. As expected, the two
indices were correlated (r^2 = 0.61) with each other and similar (P = 0.47) between
males and females.
Table 6.1. Mean (and standard error) total kidney fat indices of adult
and young mountain lions in the Black Hills
Period Age Mean SE N
1998–2003 <2.5 years 1 6 7. 59 1 7. 7 3 14
1998–2003 ≥2.5 years 161.21 20.01 11
2004–2005 <2.5 years 118.54 13.83 23
2004–2005 ≥2.5 years 114.18 19.15 12
Note: Total kidney fat is presented because Riney kidney fat indices did not differ (P > 0.05) among visual
ranks for abdominal fat.
Age × Year: P = 0.37

M = Moderate 132.45 11.23 22
H = High 215.89 1 7. 5 6 9
Notes: Lion carcasses were ranked low, medium, and high based on condition of abdominal fat.
Total kidney fat is presented because values for Riney kidney fat did not differ (P > 0.05) among visual
categories.
