Results of the model of binomial logistic regression of the probability of the character of an individual of A. ordinarium being abnormal in relation to habitat quality (RBPs scores).
The estimated parameters are α = -1.22, SD = 0.18, P-value < 0.01; β = - 0.01, SD = 0.001, P-value < 0.01 (S1 Table).
