Table 4. Positive (+) and negative (-) associations of the 14 identified daily diet types with supplementary categorical variables for season, sex, and species (χ2 tests) and supplementary continuous variables for body mass and GPS fix interval (t tests), Grand Teton National Park, Wyoming, USA, 2004–2006.

The number of symbols corresponds to P: single (0.01 ≤ P ≤ 0.05), double (0.001≤ P ≤ 0.01), triple (P ≤ 0.001).
