Table 4. GLMM results.
Five fecal glucocorticoid metabolite (FGM) measures were calculated in fishing cats (n = 24) during institutional transfers and breeding introductions that took place between 2010–2013. Mean and Peak mean FGM were both significant predictors of individuals exhibiting successful copulations.

Bold typing indicates statistically significant effects. In each model, breeding success was the dependent variable and the predictor was changed to a different cortisol measure with transfer, age and rearing as confounding variables.
