Data have been pooled across years and total sample sizes are shown on the columns. Green bars represent preferred mates and blue bars represent non-preferred mates. Intromission success (χ2=7.35, P=0.007); cub production (χ2=10.9, P=0.001); maternal rearing† (χ2=8.07, P=0.005). *indicates P≤0.05 for χ2 test. P values were obtained via χ2 tests for graphing purposes only. †Low sample sizes preclude statistical analysis in a GLMM for this variable.
